Abstract:

Introduction : L’objectif de cette étude épidémiologique était d’évaluer le besoin de traitement orthodontique sur un échantillon d’adultes vivant en France. Matériels et méthodes : L’indicateur retenu était la composante dentaire IOTN (Index of orthodontic treatment need). Résultats : Sur les 258 adultes évalués, 37 % des patients avaient un besoin important et 21 % un besoin modéré; 29 % des 35 ans et moins avaient un besoin de traitement important contre 47 % des plus de 35 ans, le besoin de traitement augmentant avec l’âge. Les anomalies occlusales les plus fréquemment rencontrées étaient les migrations dentaires suite à un édentement non compensé (situation qui concernait 22 % des sujets). Il s’agissait de la seule anomalie occlusale dont la fréquence augmentait significativement avec l’âge. Parmi les patients ayant un édentement non compensé, deux tiers avaient des migrations dentaires nécessitant un traitement orthodontique. Discussion : Certes largement utilisé dans la littérature, l’indicateur IOTN est discuté : toutes les caractéristiques évaluées sont des éléments susceptibles de perturber la longévité, le fonctionnement ou encore l’esthétique de la denture excluant ainsi toute autre considération. Le besoin de traitement chez l’adulte en France serait donc supérieur au besoin chez l’adolescent et augmenterait avec l’âge essentiellement du fait des pertes dentaires non compensées.

Abstract:

Le défaut primaire d’éruption est une anomalie peu fréquente qui se traduit par un blocage d’éruption des dents postérieures en relation avec la mutation d’un gène déterminant pour l’éruption dentaire. Il peut être aujourd’hui dépisté précocement à l’aide de méthodes d’imagerie 3D innovantes et confirmé par des examens génétiques et histologiques qui permettent de valider le diagnostic et de préciser le pronostic défavorable. La surveillance de la croissance alvéolaire des autres secteurs sera privilégiée afin d’éviter l’installation d’une asymétrie structurale et fonctionnelle. Une analyse des possibilités diagnostiques et thérapeutiques à l’aide d’ancrages osseux est réalisée à travers le suivi à long terme d’une patiente présentant un défaut primaire d’éruption lié à une mutation du gène PTHR1.

Abstract:

Le succès est matérialisé par la pérennité d’un résultat thérapeutique esthétique et fonctionnel. L’insuccès occlusal «post-orthodontique» pourrait se traduire par une instabilité dentaire, un inconfort fonctionnel jusqu’à une plainte dentaire ou musculo-articulaire. L’analyse de l’occlusion recherche les anomalies occlusales à potentialités pathogènes répertoriées en anomalies de calage, anomalies de centrage, anomalies de guidage. La grande capacité de tolérance de l’appareil manducateur rend difficile la définition de la frontière entre physiologie et pathologie, mais il est nécessaire de disposer de repères que l’on peut résumer ainsi : – calage : contact occlusal de la cuspide mésio-linguale des premières molaires maxillaires (en classe I, II ou III) et contacts occlusaux entre les canines antagonistes; – centrage : absence de décentrage transversal entre OIM et ORC; – guidage : absence d’interférence postérieure, absence d’interférence antérieure (verrouillage).

Abstract:

Introduction. Dental impaction represents the group of isolated dental anomalies characterized by retention of a tooth with a fully formed root in the jaw bone, after the eruption period has passed. This anomaly may affect deciduous teeth, permanent or supernumerary teeth causing aesthetic and / or functional disorders. Case report. The case presents a clinical situation of a girl who presented two maxillary teeth impacted (a central incisor and a cuspid) who underwent surgical exposure and orthodontic treatment for their arch alignments. Conclusions. Impacted teeth may produce dental malpositions or root resorption of the adjacent teeth, cysts or chronic local infections, which carry out a surgical orthodontic treatment, complex and for a long term, depending on the clinical situation existing.

Abstract:

Introduction : La disjonction intermaxillaire (DIM) ou expansion rapide maxillaire (ERM) est couramment utilisée par les orthodontistes pour la correction des déficits transversaux maxillaires chez les enfants et les adolescents présentant des anomalies transversales de l’occlusion dentaire et une voute palatine profonde. Cette insuffisance maxillaire transversale est souvent associée à des anomalies squelettiques antéro-postérieures de classe II ou de classe III, à des anomalies verticales et à des troubles fonctionnels, notamment de la ventilation. Elle consiste à séparer, en deux à trois semaines, les deux maxillaires droit et gauche, à l’aide d’un dispositif d’expansion fixé sur un appui dentaire ou osseux. Curieusement, les orthodontistes qui emploient souvent des dispositifs d’expansion utilisent de façon très inégale cette méthode, bien qu’elle soit le seul traitement efficace de la véritable insuffisance transversale maxillaire (ITM). Le diagnostic clinique des ITM est difficile à établir, ce qui ne permet pas de poser l’indication de la DIM avec précision. Matériels et méthodes : À partir de l’observation de la sémiologique clinique et radiologique, et de traitement de très nombreux patients, pendant plus de 45 années, il est possible de proposer un indice de diagnostic qui précise les indications de cette thérapeutique. Résultats : Cet indice de diagnostic, de maniement facile et rapide, est utilisable aisément en pratique quotidienne. Composé de quatre groupes d’items, il permet de prendre en compte tous les éléments nécessaires à la pose de l’indication médicale de la disjonction intermaxillaire. Il permet également d’évaluer son efficacité en comparant les scores avant et après traitement. Discussion : Bien que perfectible, il n’existe pas actuellement d’outil diagnostique comparable. Cet indice a pour objectif de préciser l’indication médicale de cette méthode et de réduire les disparités d’emploi de cette thérapeutique.

Abstract:

Introduction : Le rôle des amygdales palatines obstructives dans la genèse des anomalies des relations des arcades dentaires est largement évoqué dans la littérature orthodontique mais reste controversé. Les données fournies sur la probable relation entre l’hypertrophie des amygdales et l’existence de ces anomalies sont subjectives. L’objectif de cette étude est de rechercher une association entre les amygdales palatines obstructives et des anomalies des relations d’arcades. Matériels et méthodes : Il s’agit d’une étude transversale réalisée chez des enfants âgés entre 6 et 12 ans. Les sujets sont divisés en deux groupes (A et B) selon le caractère obstructif des amygdales palatines. Sur chaque enfant, des mensurations intra- et inter-arcades ont été réalisées. Un test t et un chi2 ont respectivement été réalisés pour comparer les variables quantitatives et qualitatives selon le caractère obstructif des amygdales. Lorsque le nombre de cas était faible, le chi2 a été remplacé par le test exact de Fisher. La signification est fixée à p = 0,05. Résultats : La profondeur d’arcade est significativement plus marquée dans le groupe B. Le groupe A présente les plus grands diamètres transversaux d’arcades. Le groupe B a significativement tendance aux rapports molaires de classe II, à l’infraclusion antérieure et à une occlusion croisée postérieure avec une latéro-déviation mandibulaire. Conclusion : Une évaluation précoce des enfants présentant une hypertrophie des amygdales permettrait de prévenir les effets sur les arcades dentaires. Ainsi, seront évités les traitements tardifs et plus agressifs qui ne sont pas toujours aussi efficients que lorsqu’ils sont effectués pendant l’enfance.

Abstract:

Le syndrome de Brodie unilatéral est une forme rare de malocclusion, souvent accompagnée d’une asymétrie faciale de sévérité variable. Les anomalies du sens transversal chez l’adulte sont très difficiles à traiter en particulier dans les cas incluant aussi un chevauchement des molaires dans le sens vertical. Ce rapport de cas illustre l’utilisation de mini-vis orthodontiques pour le traitement d’un syndrome de Brodie unilatéral chez un adulte d’âge moyen. Un ancrage absolu et des dispositifs orthodontiques linguaux fixes permettent de traiter efficacement les anomalies dentaires, alvéolaires et fonctionnelles associées au syndrome de Brodie unilatéral. Les documents colligés chez ce patient avant et après le traitement et la période de contention prouvent l’efficacité et la stabilité des résultats du traitement, avec peu d’effets secondaires indésirables.

Abstract:

We have previously described hypomorphic reelin (Reln) mutant mice, RelnCTRdel, in which the morphology of the dentate gyrus is distinct from that seen in reeler mice. In the RelnCTRdel mutant, the infrapyramidal blade of the dentate gyrus fails to extend, while the suprapyramidal blade forms with a relatively compact granule neuron layer. Underlying this defect, we now report several developmental anomalies in the RelnCTRdel dentate gyrus. Most strikingly, the distribution of Cajal-Retzius cells was aberrant; Cajal-Retzius neurons were increased in the suprapyramidal blade, but were greatly reduced along the subpial surface of the prospective infrapyramidal blade. We also observed multiple abnormalities of the fimbriodentate junction. Firstly, progenitor cells were distributed abnormally; the “neurogenic cluster” at the fimbriodentate junction was absent, lacking the normal accumulation of Tbr2-positive intermediate progenitors. However, the number of dividing cells in the dentate gyrus was not generally decreased. Secondly, a defect of secondary glial scaffold formation, limited to the infrapyramidal blade, was observed. The densely radiating glial fibers characteristic of the normal fimbriodentate junction were absent in mutants. These fibers might be required for migration of progenitors, which may account for the failure of neurogenic cluster formation. These findings suggest the importance of the secondary scaffold and neurogenic cluster of the fimbriodentate junction in morphogenesis of the mammalian dentate gyrus. Our study provides direct genetic evidence showing that normal RELN function is required for Cajal-Retzius cell positioning in the dentate gyrus, and for formation of the fimbriodentate junction to promote infrapyramidal blade extension.

Abstract:

Object The CT modality plays a central role in the diagnosis of cervical spine fractures. In childhood, radiolucent synchondroses between ossification centers can resemble fractures, and they can be the sites of fractures as well. Recognition of cervical spine fractures in children requires familiarity with normal developmental anatomy and common variants as they appear on CT scans. Methods A convenience sample of 932 CT scans of the cervical spine accessible on the picture archiving and communications system (known as PACS) at a single children's hospital was examined. Scans were excluded from further analysis if they did not include the atlantoaxial region or were otherwise technically unsatisfactory; if the patient carried the diagnosis of a skeletal dysplasia; or if there were developmental lesions noted at other levels of the spine. No more than 1 scan per patient was analyzed. Synchondroses were graded as radiolucent, not totally radiolucent but still visible, or no longer visible. Their locations and symmetries were noted. The presence or absence of the tubercles of the transverse ligament was noted as well. Results After exclusions, 841 studies of the atlas and 835 studies of the axis were analyzed. The 3 common ossification centers of the atlas arose in the paired neural arches and the anterior arch, but in as many as 20% of cases the anterior arch developed from paired symmetrical ossification centers. The 5 common ossification centers of the axis arose in the paired neural arches, in the basal center, in the dentate center (from which most of the dentate process develops), and in the very apex of the dentate process. The appearance of each synchondrosis was noted at sequential ages. The tubercles for the transverse ligament generally did not appear until the ossification of the synchondroses of the atlas was far advanced. Anomalies of the atlas included anterior and posterior spina bifida, absence of sectors of the posterior arch, and anomalous ossification centers and synchondroses. Anomalies of the axis were much less common. What appeared possibly to be chronic, incompletely healed fractures of the atlas were discovered on review for this analysis in 6 cases. No fractures of the axis were discovered. Conclusions There is substantial variation in the time course and pattern of development of the atlas, and anomalies are common. Some fractures of the atlas may escape recognition without manifest sequelae. Variation in the time course of the development of the axis is notable as well, but anomalies seem much less common.

Abstract:

ZusammenfassungViele kieferorthopädisch relevante Anomalien können nicht allein durch den Kieferorthopäden behandelt werden, sondern bedürfen der Unterstützung der weiteren Fachdisziplinen der Zahnheilkunde, allen voran der Mund-, Kiefer- und Gesichtschirurgie. Die Schnittstellen beider Disziplinen sind dabei vielfältig und breit gefächert – sie umfassen nicht allein das Spektrum der Dysgnathie-Operationen im Erwachsenenalter zur Korrektur skelettaler transversaler, vertikaler und sagittaler Lageanomalien der Kiefer, dem natürlich der größte Anteil zukommt, sondern auch oralchirurgische Eingriffe, welche in Zusammenhang mit kieferorthopädischen Maßnahmen erforderlich werden. Hierzu zählen die Entfernung überzähliger und aus Platzgründen zu extrahierender bleibender Zähne, als auch die chirurgische Freilegung verlagerter und retinierter Zähne. Im Rahmen von Nichtanlagen stellen oftmals implantat-prothetische Versorgungen nach entsprechender Pfeilerverteilung und Lückenöffnung eine gute Versorgungsmöglichkeit zur oralen Rehabilitation der Patienten dar, was eine enge interdisziplinäre Planung zur optimalen Vorbereitung der notwendigen Insertion dentaler Implantate erfordert. Im folgenden Artikel soll ein Überblick über die vielfältigen Schnittstellen zwischen der Kieferorthopädie und der Mund-, Kiefer- und Gesichtschirurgie anhand ausgewählter Patientenfälle gegeben werden sowie die besonderen Erfordernisse in der interdisziplinären Therapieplanung.

Abstract. Osseous anomalies/pathologies in the Late Cretaceous cryptobranchid salamander Eoscapherpeton asiaticum from the Turonian Bissekty Formation of Uzbekistan are analyzed using gross morphological description, microCT, and histologic analysis. These pathologies result from trauma (fractured and subsequently healed dentary and femora; hematoma on femur), possible infection due to trauma (prearticular with exostosis and necrotic cavities; anterior trunk vertebra and fused vertebra with pathological enlargements formed during reactive periosteal growth) and congenital disorders (hemivertebra and fused vertebrae with shortened asymmetrical centra and abnormal arrangements of transverse processes). The origin of the pathologies of two atlantal specimens (enlargement of transverse processes) is unclear. Our report of hemivertebra in Eoscapherpeton is the first occurrence of this congenital pathology in a fossil lissamphibian. The occurrence of several traumatic femoral pathologies in Eoscapherpeton could be a result of intraspecific aggressive behavior. Bone pathologies are described for the first time in fossil salamanders.

Introduction : Actuellement, 1 sur 900 adultes âgés de 16 à 44 ans est un survivant d’un cancer de l’enfance. Le taux global de survie pour tous les types de cancers de l’enfance approche des 80 % et les progrès dans le traitement et les soins continuent à offrir des résultats prometteurs. Des années après leur traitement, ces enfants, malgré leurs problèmes de santé chronique, aspirent à avoir, dans la mesure du possible, un accès aux soins orthodontiques à l’instar des enfants en bonne santé. Objectifs : Pour répondre à cette nécessité et aux difficultés thérapeutiques que rencontrent les orthodontistes face à ces patients, nous avons mené une étude transversale épidémiologique au Centre anticancéreux Léon Bérard à Lyon. L’objectif était de recenser les besoins de traitement orthodontique des enfants de plus de 7 ans ayant reçu un traitement antinéoplasique par radiothérapie de la région cranio-cervico-faciale. Résultats : Notre étude conclut que les enfants ayant reçu une irradiation de la région cranio-faciale présentent des retards de croissance, une dissymétrie faciale dans 74 % des cas, un recouvrement et surplomb incisifs augmentés dans respectivement 70 % et 61 % des cas. Les anomalies de développement dentaire sont retrouvées chez 83 % des patients et représentées par des microdonties, des fermetures apicales prématurées et des hypoplasies. Nous retrouvons des troubles trophiques tels que l’hyposialie. Enfin, le besoin de traitement est avéré pour 61 % des patients, modéré dans 17 % des cas; il est lié à l’absence ou rétention de dents et à l’augmentation du surplomb incisif.

Abstract:

<p>As fissuras labiopalatinas correspondem às malformações craniofaciais mais prevalentes na espécie humana. É indispensável durante o processo reabilitador destas anomalias, a existência de condições adequadas de saúde bucal para a realização das cirurgias reparadoras primárias e secundárias. Considerando que nas crianças os órgãos e tecidos estão em desenvolvimento, apresentando peculiaridades fisiológicas e farmacocinéticas, a prescrição medicamentosa pediátrica deve ser uma prática cautelosa; além do mais, o uso de antibióticos pode acarretar alterações na microbiota normal do trato gastrintestinal. Por sua vez, o HRAC/USP utiliza cefazolina endovenosa para tratamento profilático nos procedimentos cirúrgicos reparadores em crianças com fissuras. O uso de antimicrobianos de ação sistêmica pode causar sérias reações adversas incluindo distúrbios gastrintestinais, erupções cutâneas e em casos mais graves, choque anafilático. Desse modo, as infecções dentais neste grupo infantil, quando possível, devem ser tratadas sem o uso de antibióticos, limitando sua administração apenas aos casos mais graves associados a comprometimentos sistêmicos.</p>

Background:Alcohol exposure during development has detrimental effects, including a wide range of physical, cognitive and neurobehavioural anomalies known as foetal alcohol spectrum disorders. However, alcohol consumption among pregnant woman is an ongoing latent health problem.Aim:In the present study, the effects of trichostatin A (TSA) on emotional and cognitive impairments caused by prenatal and lactational alcohol exposure were assessed. TSA is an inhibitor of class I and II histone deacetylases enzymes (HDAC), and for that, HDAC4 activity was determined. We also evaluated mechanisms underlying the behavioural effects observed, including the expression of brain-derived neurotrophic factor (BDNF) in discrete brain regions and newly differentiated neurons in the dentate gyrus (DG).Methods:C57BL/6 female pregnant mice were used, with limited access to a 20% v/v alcohol solution as a procedure to model binge alcohol drinking during gestation and lactation. Male offspring were treated with TSA during the postnatal days (PD28–35) and behaviourally evaluated (PD36–55).Results:Early alcohol exposure mice presented increased anxiogenic-like responses and memory deterioration – effects that were partially reversed with TSA. Early alcohol exposure produces a decrease in BDNF levels in the hippocampus (HPC) and prefrontal cortex, a reduction of neurogenesis in the DG and increased activity levels of the HDAC4 in the HPC.Conclusions:Such findings support the participation of HDAC enzymes in cognitive and emotional alterations induced by binge alcohol consumption during gestation and lactation and would indicate potential benefits of HDAC inhibitors for some aspects of foetal alcohol spectrum disorders.

Abstract:

Objectives: The temporomandibular joints (TMJs) play a fundamental role in mastication, deglutition, speech, and even respiration. Thus, temporomandibular disorders (TMDs) can affect the quality of life, especially if they become chronic. Considering the controversy regarding the etiology of the TMDs, this study aimed to assess the relationship of TMDs with dental malocclusion. Materials and Methods: Totally, 885 dentate patients between 18 years and 60 years with complete dental records and no condylar ankylosis, history of trauma, bruxism, clenching, or congenital TMJ anomalies participated in this study. Tenderness on palpation, clicking, crepitus, pain, deviation on mouth opening, open bite, deep bite, cross bite, and class of malocclusion (I, II or III) were recorded for all patients. Results: Of patients, 60.2% were males and 39.8% were females. Gender had no correlation with TMDs. Patients had a mean age of 34.8 years. Age had no correlation with TMDs. Of TMD symptoms, clicking had the highest frequency (23.3%) followed by deviation on mouth opening (10.6%), pain at the mouth opening (2.9%), tenderness on palpation (1.4%), trismus (1.2%), and crepitus (1.1%). Of patients, 76.7% were Class I, 13.8% were Class II, and 6.2% were Class III. Less than 2% of patients had deep bite, open bite, or cross bite. Conclusion: TMDs had a relatively high prevalence (35%) in our study population. Age, gender, and class of malocclusion had no correlation with TMDs; however, Class II malocclusion was slightly more prevalent among TMD patients, which needs to be taken into account by patients and orthodontists.

Abstract:

L'action carioprotectrice du fluor par voie topique est reconnue depuis plus d’une cinquantaine d’année. Ce dernier est devenu aujourd’hui, l'un des piliers de la prévention de la maladie carieuse. Toutefois, l’ingestion excessive de cet oligo-élément durant les premières années de la formation des dents peut entrainer l’apparition d’une fluorose dentaire. Il s’agit d’une anomalie de structure acquise pré-éruptive caractérisée par un aspect polymorphe variant en fonction de la sévérité d’atteinte. Elle peut engendrer, dans certains cas, en fonction de son impact sur la couleur et l'aspect de surface de l'émail dentaire, un préjudice esthétique et fonctionnel majeur. Pour pallier cette problématique, la dentisterie moderne propose un vaste champ thérapeutique allant de l’éclaircissement aux restaurations prothétiques. L’objectif principal est d’adopter une thérapeutique adaptée selon chaque situation tout en étant le moins invasif possible. C’est dans cette optique que ce travail se propose de présenter la gestion thérapeutique d’une fluorose dentaire chez une patiente âgée de 14 ans. Le traitement a consisté en la combinaison de deux méthodes : la micro-abrasion et l’éclaircissement externe ambulatoire ce qui a permis d’obtenir un résultat très satisfaisant pour la patiente, tout en respectant le principe d’économie tissulaire.

Abstract:

Foi estudada a influência da droga antimitótica 5-fluoruracil (5-FU), administrada a ratas prenhes sobre a formação do germe dental de ratos recém nascidos. Foram utilizadas 125 fêmeas com 90-100 dias de idade e 15 machos adultos (Rattus rattus norvaegicus, albinus, Wistar). A droga foi injetada por via intraperitoneal a ratas grávidas, em doses únicas, aos 9º, 10º, 11º , 12º ou 13 º dias de gestação. Os animais foram divididos em quatro subgrupos de acordo com a dose administrada: 10, 20, 30 e 40 mg/kg. Os resultados mostraram que nessas doses, o 5-FU não teve efeito tóxico nas ratas prenhes, alem de perda de peso com doses mais elevadas (30-40 mg/kg), enquanto causou anomalias dentais nos embriões, bem como malformações externas. A proporção de tais anomalias foi, alem de dose dependente, influenciada pelo dia de gestação no qual antimitótico foi administrado às mães: foi observada maior sensibilidade ao 9º dia e menor ao 10º dia. Doses mais elevadas (30-40 mg/kg) causaram freqüentemente morte do embrião e reabsorção fetal. Agenesia do germe dentário foi freqüentemente observada. Abstract It was studied the influence of the antimitotic drug 5 - fluorouracil (5-FU), administered to pregnant rats, on dental germ formation of newborn rats. A total of 125 female aged 90-100 days and 15 male adult rats (Rattus rattus norvaegicus, albinus, Wistar) were used. The drug was injected intraperitoneally in single doses to females at the 9th, 10th, 11th, 12th and 13th days of pregnancy. The animals were divided in four groups according to the doses administered: 10, 20, 30 and 40 mg/kg. Results show that the drug induced no toxicity to mothers, other than loss of body weight with higher doses (30-40 mg/kg), but caused in the fetuses dental germ anomalies and body external malformations. The proportion of such anomalies were, besides dose dependent, influenced by the day of pregnancy when the drug was administered to the mothers: there was a greater sensitivity at the 9th day and a lesser one at the 10th day. Higher doses (30-40 mg/kg) caused frequently embryonic death or fetal uterine reabsorption. Agenesia of the dental germ was frequently found.

Abstract:

O aparecimento de um ou mais dentes que excedam a quantidade normal na arcada dentaria é denominado de supranumerário. Estes dentes podem ser encontrados nas dentições decídua e permanente, podendo ocorrer de varias formas, tamanhos e em diferentes locais do arco dentário. Os dentes supranumerários que irrompem entre os incisivos são chamados de mesiodens, após o 3° molar são os distomolares e entre molares e pré-molares são os paramolares ou pré-paramolares. Ocorre com maior prevalência na maxila e o mais comum é o mesiodens. O objetivo desse trabalho é relatar um caso de supranumerário mandibular em localização atípica. Paciente do sexo feminino, 22 anos queixa-se da presença de uma estrutura pequena e endurecida entre os dentes inferiores. O exame clínico e os recursos de imagens revelaram a presença de um dente supranumerário localizado entre os dentes 46 e 47 cujo diagnóstico foi de um paramolar. A literatura revela que esta anomalia dentária é rara, principalmente entre o 1° e 2° molar mandibular. Atualmente, os recursos imaginológicos são imprescindíveis para o correto diagnóstico, pois em alguns casos os dentes estão fusionados o que dificulta a sua remoção; e se a imagem não for bem detalhada pode induzir o profissional ao erro.

Abstract:

Introdução: Agenesia é uma anomalia do desenvolvimento dentário frequente no ser humano, e é representada pela ausência de um ou mais dentes, fato relacionado com problemas estéticos e de maloclusão. Objetivo: Investigar a presença de agenesia dental, por meio de radiografias panorâmicas. Materiais e métodos: Foram avaliadas radiografias de pacientes atendidos em três clínicas odontológicas de Presidente Prudente (SP), relacionando a frequência da agenesia com o gênero, quadrantes e grupos dentários afetados. Os critérios de exclusão foram idade e perdas dentais por extrações ou outros motivos. A avaliação das tomadas radiográficas foi executada por dois avaliadores, utilizando negatoscópio em ambiente escuro para possibilitar a análise. Resultados: Foram avaliadas 600 radiografias panorâmicas de pacientes na faixa etária entre 9 e 16 anos. Foram encontrados 171 casos de agenesia; destes, 82 casos foram observados no gênero masculino e 89, no feminino. Quando avaliado o tipo de dente, os terceiros molares apresentaram maior frequência de agenesias (65%), seguido dos segundos pré-molares (5,8%), incisivo lateral (4,8%), primeiro pré-molar e incisivo central (0,6%) em todos os quadrantes, sendo mais frequente no quadrante superior e no gênero feminino. Conclusão: Há prevalência de agenesias no arco superior, com destaque para a do terceiro molar em relação ao de outros dentes. Adicionalmente, sugere-se que o gênero não é um fator predisponente para presença de agenesia.

Abstract:

Abstract Purpose Only a few but conflicting results have been reported on the association between malocclusions and caries. We investigated this association using data from the population-based cross-sectional Study of Health in Pomerania (SHIP). Methods Sagittal, vertical and transversal intermaxillary relationship, space conditions and sociodemographic parameters of 1210 dentate subjects (median age 30 years, interquartile range 25–35 years) were collected. Caries was assessed with the Decayed-Missing-Filled Surfaces index but analyzed as ordered outcome (four levels: sound, enamel caries, caries, tooth loss) in ordinal multilevel models, taking into account subject, jaw, and tooth level simultaneously. Results Anterior open bite ≤3 mm (odds ratio [OR] = 2.08, 95% confidence interval [CI]: 1.19–3.61), increased sagittal overjet of 4–6 mm (OR = 1.31, CI: 1.05–1.64), distal occlusion of ½ premolar width (OR = 1.27, CI: 1.05–1.53) and distal 1 premolar width (OR = 1.31, CI: 1.06–1.63) were associated with adjusted increased odds for a higher outcome level (caries). Anterior spacing (OR = 0.24, CI: 0.17–0.33), posterior spacing, (OR = 0.69, CI: 0.5–0.95), posterior crowding (OR = 0.57, CI: 0.49–0.66) and buccal nonocclusion (OR = 0.54, CI: 0.33–0.87) were associated with a lower outcome level (caries). Conclusion The results from this population-based study suggest that a connection between caries and malocclusion exists to a limited extent in young adults. The associations with caries are contradictory for several malocclusion variables. Distal occlusion (OR = 1.31, CI: 1.06–1.63) and related skeletal anomalies displayed positive associations with caries whereas crowding did not. Orthodontic treatment of anterior crowding would probably not interfere with caries experience. These aspects should be considered for patient information and in treatment decisions.

Abstract:

Abstract Background A horseshoe kidney is a congenital malformation involving the fusion of the bilateral kidneys and is often accompanied by anomalies of the ureteropelvic and vascular systems. When performing resection of colorectal cancer in a patient with horseshoe kidney, damage to the ureter or excessive renal arteries should be avoided. To achieve this purpose, comprehensive preoperative anatomical assessments and surgical planning are important. Here, we report a case of a laparoscopic abdominal perineal rectal resection for lower rectal cancer with a horseshoe kidney. Case presentation A 79-year-old woman presented with bloody stool and was diagnosed with advanced lower rectal cancer, immediately above the rectal dentate line, without metastasis. A preoperative computed tomography (CT) scan revealed a horseshoe kidney, while a three-dimensional CT (3D-CT) angiography revealed aberrant excess renal artery from the aorta to the renal isthmus. The left ureter ran in front of the isthmus of the horseshoe kidney and presented calculus formation. Laparoscopic abdominal perineal rectal resection was performed with D3 lymph node dissection. During the operation, we mobilized the sigmoid colon mesentery via a medial approach and preserved the left ureter, the left gonadal vessels, and the hypogastric nerve plexus in the retroperitoneum in front of the horseshoe kidney. Conclusions We report a rare case of rectal cancer surgery in a patient with a horseshoe kidney. We discuss the anatomical peculiarities of a horseshoe kidney, such as excess renal arteries, inferior vena cava, ureter, gonadal vessels, and nerves, that should be preserved according to the literature. We suggest that preoperative 3D-CT angiography is both useful for revealing the relationship between the vascular system and a horseshoe kidney and helpful when performing laparoscopic surgery for a left-sided colon and rectal cancer to avoid intraoperative injury.
