Resumen
Anodontia is a rare orofacial complex developmental malformation. In contrast to normal tooth germ with roundhypo echogenic structure arranged in an arch-like manner in alveolar bone, anodontia shows an arch-like hyper echogenic structure without any dental alveoli. Prenatal ultrasound is a reliable method for detecting anodontia inearly gestational age.

Resumen
Background / Aim. Data regarding tooth absence among Romania military personnel are lacking. The purpose of this study was to determine the prevalence of dental anomalies among military students at a military technical academy in Bucharest, Romania. Methods. A cohort of 318 military students enrolled the study. Each participant underwent an extensive evaluation of their oro-dental health status based on guidelines of the EGOHID II (European Global Oral Health Indicators Development II Project). Results. Anodontia was discovered in 6/318 participants (prevalence rate, 1.9%), namely 4 women (prevalence among women, 4.6%) and 2 men (prevalence among men, 0.87%). Five of the six patients were previously undiagnosed. The most commonly affected teeth were second premolars (n = 8), followed by first premolars (n = 4) and second permanent molars (n = 2). Premolar anodontia was equally common in the maxilla and the mandible; both instances of molar anodontia were in the mandible. None of the participants with anodontia had remaining temporary teeth. A brief overview of the case of two of the presently diagnosed patients, who presented with inferior bilateral second molar anodontia and quadruple canine inclusion and a quadruple second premolar anodontia, is included. Conclusion. Military students in Romania would benefit from systematic dental evaluation and long-term monitoring prior to the enrollment the Military Academy.

Resumen
ABSTRACT Ectodermal dysplasia (ED) is a heritable condition and represents a multifarious group of diseases comprising different clinical signs and symptoms. The ED occurs as a result of disturbances in the ectoderm of the evolving embryo. Agenesis of teeth or anodontia is also the result of disturbance in this process, which prevents the proliferation of tooth buds. In the present case, an 18-month-old child with history of congenital anomalies (CAs), severely delayed developmental milestones, and mental retardation presented with complete anodontia and ED. The CA included pulmonary stenosis, pulmonary valvar regurgitation, ventricular septal defect (VSD), absence of grips, absence of head-holding capacity, inability to sit, simian crease (R), visual impairment with corectopia, blepharitis, lagophthalmos with cortical visual impairment, telecanthus, hypotrichosis, hypertelorism, high philtrum, high arched palate, degenerated nails, and depressed third toes. Routine karyotyping via peripheral blood culture revealed a ring chromosome 18, which was confirmed de novo after parental karyotyping. Although a straightforward association between r(18) and anodontia is yet to be established, it is apparent that anodontia coupled with multiple CA and systemic complications was caused by chromosomal/genetic mutations in the present case, and thus, this report strongly recommends phenotypic and genotypic examination in dental management in such a complex scenario.

Resumen
Ectodermal dysplasia is a rare hereditary disorder with a characteristic physiognomy. The case of a 5-year-old child with hypohidrotic ectodermal dysplasia and complete anodontia is presented. Because of the anodontia and the need for treatment at an early age, the prosthetic management of such a young child can be difficult. Complete dentures were provided to encourage a normal psychological development and to improve the function of the stomatognathic system.

Resumen
Abstract Aim: This article is set on presenting various types of anodontia, the most frequent types found in a dental office and to bring awareness to parents and also the dentists on the signs of agenesis and its consequences in time. Material and method: for a year (1st September 2017 – 31th August 2018) various patients with different types and locations of anodontia were diagnosed correctly by an oral and radiological exam in a dental office. Results. Anodontia is found almost equally in both sexes without major differences between males and females. Real agenesis is most frequently found in the second premolars – study reports show that this is because of phylogenetic evolution. False agenesis is more frequent in the 3rd molars because they are most likely extracted. Third molars are usually extracted because they don’t have space to emerge on the maxilla or mandible or they emerge in a vicious position. Canine agenesis has a very low frequency. Conclusions: It is very important to do a thorough check-up and a correct case history followed by radiological investigations each time a suspicion of a possible anodontia exists. It can only be certainly diagnosed by having a full oral and radiological exam. Also a difference must be made between the real, false and pseudoanaodontia.

Abstract. Title of the paper: Genetic analysis of congenital hypotrichosis with anodontia in cattle In three male German Holstein calves, black and white spotted, congenital hypotrichosis and nearly complete anodontia was observed. The pedigree of the probands being maternal halfsibs and grandmatemal grandsons supports a monogenic, X-linked recessive inheritance. Chromosomal Xq-deletions were not detected. Similar congenital anomalies are known in tabby mice and in humans as anhidrotic ectodermal dysplasia (EDI, EDA). The human gene causative for EDI and the Tabby gene are located on the X-chromosome. Therefore, the moleculargenetic marker analysis in our material was restricted on the X-chromosome. Using identical by descend mapping based on 20 microsatellites, we were able to identify an exclusively Joint genomic region on the long arm of the X-chromosome among the affected calves. The putative location of the gene locus for congenital hypotrichosis with anodontia maps into the region of the marker BM4604 on position 76.5 cM of the X-chromosome.

Resumen
Le Cuivre (Cu) appartient aux métaux majeurs contaminant les écosystèmes dulcicoles européens. Les bivalves sont des filtreurs qui bioaccumulent fortement les métaux lourds comme le Cu, lequel, en excès cause de graves troubles métaboliques, et physiologiques. Le but de cette thèse est d'étudier les mécanismes de toxicité et de détoxication du cuivre chez Anodonta cygnea et Anodonta anatina, bivalves largement répandus dans les eaux continentales. L'effet du Cu a d'abord été étudié sur le transport cellulaire du calcium (Ca). Le Ca intervient dans de nombreux processus biologiques et le métabolisme calcique est connu pour être perturbé par le Cu chez les mollusques. L'inhibition par le Cu de l'activité de la Ca2+-ATPase de la membrane plasmique (PMCA) a été observée après 4 jours d'exposition. La récupération totale de l'activité enzymatique a été notée dans les reins et les branchies, après 7 jours d'exposition à concentration environnementale, mais pas à plus forte concentration. L'inhibition des PMCA pourrait entraîner des perturbations de l'osmorégulation et de la réabsorption rénale du calcium chez les moules et conduire à une carence. La récupération de l'activité enzymatique suggère l'induction de mécanismes de détoxications. Les composés riches en thiol, impliqués dans l'homéostasie et la détoxication des métaux ont donc été étudiés dans une seconde étape. Nos résultats montrent la présence d'un peptide riche en cystéine, différent du glutathion, et détecté dans la glande digestive et les branchies des bivalves exposés ou non au Cu. Ce peptide, augmente significativement dans les branchies, après exposition au Cu suggérant son implication dans sa détoxication
Copper (Cu) belongs to the major metals causing environmental contamination in European fresh water ecosystems. Filter feeding bivalves have a high bioaccumulation potential for heavy metals as Cu, which at high concentration can cause serious metabolic, physiological impairments. The objectives of this thesis are to acquire knowledge about toxic effects and detoxification mechanisms of Cu in Anodonta cygnea and Anodonta anatina, two mussels species widely distributed in continental waters. Because calcium (Ca) plays a fundamental role in numerous biological processes, Cu effect was studied first on cellular calcium transport which is known to be disturbed by Cu in molluscs. In a second step, investigations have been carried out on Cu detoxification mechanisms by thiol compounds known to be involved in homeostasis of essential trace metals and in metals cell detoxification. Cu inhibited plasma membrane Ca2+-ATPase (PMCA) activities upon 4 days of exposure was obtained. Total recovery was observed at day 7 in kidneys and gills under exposure to environmental Cu concentration but not at higher level of exposure. PMCA inhibition may entail disturbance of osmo-regulations and calcium renal re-uptake in mussels and lead to continuous under-supply of Ca. Recovery of the enzyme function suggests that metal-detoxification is induced. Our results showed the presence of a cysteine-rich peptide different from glutathione, detected in the digestive gland and the gills from controls and Cu exposed bivalves. This peptide, observed in absence of metal exposure in both organs, increased significantly in gills after Cu exposure suggesting its implication in Cu detoxification mechanisms

Resumo: Fissuras do lábio e/ou palato (FL/P) representam a anomalia congênita mais comum em humanos. FL/P podem estar associadas a outras malformações, caracterizando uma síndrome, ou apresentar-se de forma isolada, recebendo a denominação não-sindrômica (FL/PNS). A etiologia das FL/PNS é complexa e envolve a participação de inúmeros genes, os quais estão sobre a influência de fatores ambientais. Alguns estudos demonstraram uma frequência elevada de anomalias dentais em pacientes com FL/PNS, sugerindo um defeito genético único para essas duas alterações. Os objetivos deste estudo foram: 1) verificar se polimorfismos nos genes responsáveis por síndromes que apresentam FL/P em seu espectro clínico, incluindo TP63, MID1, PVRL1, RUNX2 e TBX1, podem contribuir para a etiologia das FL/PNS, e 2) determinar a frequência de anomalias dentais em pacientes com FL/PNS. Sete regiões polimórficas foram genotipadas por PCR-RFLP (reação em cadeia da polimerase associada à análise de polimorfismo de fragmentos de restrição enzimática) em amostras de DNA provenientes de 367 pacientes afetados por FL/PNS (grupo experimental) e de 413 indivíduos clinicamente normais (grupo controle). Para determinar a frequência de anomalias dentais em pacientes com FL/PNS, 296 pacientes com idade entre 12 e 30 anos, sem história de extração dental e tratamento ortodôntico prévio e que apresentavam documentação radiográfica foram avaliados. Dos 7 prováveis polimorfismos, apenas 3 foram confirmados em nossa população. Após correção para múltiplas comparações pelo teste de Bonferroni, apenas o polimorfismo rs28649236 do gene TBX1 demonstrou diferença significante entre os grupos. O alelo G e os genótipos AG e GG ocorreram em uma frequência significantemente maior no grupo controle que no grupo experimental, e na presença do alelo G um efeito protetor para o desenvolvimento de FL/PNS foi observado (p=0,0002; OR: 0,41; IC 95%: 0,25-0,67). Anomalias dentais foram identificadas em 57,7% (n=296) dos pacientes com FL/PNS e pacientes com FL foram significantemente menos acometidos por anomalias dentais comparando-se com pacientes com FP ou FLP (p=0,004). Agenesia dental foi a mais frequentemente identificada entre os tipos de fissura, principalmente em pacientes com FLP e FP que em pacientes com FL (p=0,03). O presente estudo demonstrou que o polimorfismo rs28649236 do gene TBX1 apresenta um efeito protetor para o desenvolvimento de FL/PNS em uma população brasileira e que o risco de pacientes com FLP ou FP apresentar anomalias dentais é significantemente maior que o de pacientes com FL. Em adição, este estudo corrobora com evidências prévias que demonstraram a influência de genes responsáveis por síndromes contendo FL/P na etiopatogenia das FL/PNS.
Abstract: Cleft lip and/or cleft palate (CL/P) is the most common congenital anomaly in humans. CL/P may be associated with other malformations, featuring a syndrome, or present itself in an isolated form, denominated nonsyndromic (NSCL/P). NSCL/P etiology is complex and involves the participation of numerous genes, which are under the influence of environmental factors. Some recent studies have demonstrated a high frequency of dental anomalies in patients with NSCL/P, suggesting a common genetic defect for these two alterations. The objectives of this study were: 1) to verify whether polymorphic variants of genes responsible for syndromes that have CL/P in their clinical spectrum, including TP63, MID1, PVRL1, TBX1 and RUNX2, may contribute to the etiology of NSCL/P, and 2) to determine the frequency of dental anomalies in patients with NSCL/P. Seven polymorphic regions were genotyped by PCR-RFLP (restriction fragment length polymorphism-polymerase chain reaction) in DNA samples from 367 patients affected by NSCL/P (experimental group) and 413 clinically normal subjects (control group). To determine the frequency of dental anomalies in patients with NSCL/P, 296 patients aged between 12 and 30 years without history of tooth extraction and orthodontic treatment and with radiographic documentation were evaluated. Out of 7 probable polymorphisms, only 3 were confirmed in our population. After correction for multiple comparisons by Bonferroni test, only rs28649236 TBX1 polymorphism showed significant difference between groups. The allele G and the AG and GG genotypes occurred in a significantly higher frequency in controls than in the experimental group, and in the presence of the G allele a protective effect against NSCL/P was observed (p=0.0002; OR: 0.41; 95% CI: 0.25-0.67). Dental anomalies were identified in 57.7% (n= 296) of patients with NSCL/P and patients with CL were significantly less affected by dental anomalies compared with patients with CP or CLP (p=0.004). Dental agenesis was the most frequently identified among the cleft types, especially in patients with CLP and ICP than in patients with FL (p=0.03). The present study demonstrated that rs2864923 TBX1 polymorphism has a protective effect in NSCL/P development in a Brazilian population, and patients with CLP or CP are frequently more affected by dental anomalies than patients with CL. In addition, this study corroborates with previous evidences demonstrating the influence of genes related to syndromes containing CL/P on etiopathogenesis of the NSCL/P.

Resumen
Av Sveriges åtta stormusselarter är tre (Margaritifera margaritifera, Unio crassus och Pseudanodonta complanata) hotade (Lundberg & Tapper 2005). Om de övriga fem är kunskapen knapp (Gustavsson 2007) men studier som har gjorts i bl.a. Västra Götalands län tyder på att det råder underskott av individer i de yngre åldersklasserna och av juveniler i musselpopulationerna. Detta kan leda till att musselpopulationer kommer att dö ut (Bergengren & Lundberg 2008). Faktorer som stör musslorna och som gör att de minskar i antal är bl.a. eutrofiering, parasiter och försurning. Allmän dammussla (Anodonta anatina) är den vanligaste arten av stormusslor och den hittas i större delen av Sverige (Bergengren et al 2002). Denna art är mest tålig och klarar av att leva i de flesta vatten utom de mest näringsfattiga (Eckhard & Weber 2005). Detta arbete har utförts under april och maj 2009 vid Östads badplats i Bullarebygden i Norra Bohuslän. Platsen har tidigare (2008) inventerats av länsstyrelsen och då lades det en provyta på 30 kvadratmeter där musseltillgången var synbart god (Ingvarsson et al 2009). Det hittades då 33 individer av arten allmän dammussla och viss föryngring förekom. Under 2009 undersöktes 150 kvadratmeter och då inte enbart områden där tillgången på musslor var synbart god. Detta beroende på möjligheten att juvenila individer kan uppehålla sig på andra platser än adulter. Inventeringen utfördes på tre olika djup ( 20 cm, 60 cm och 100 cm) med hjälp av vattenkikare och sedimentprovtagare. Endast musslor av arten allmän dammussla hittades. För att föryngringen av musslorna skulle räknas som god krävdes det att 10 % av populationen var juvenil. Fanns det juveniler med andelen var färre än 10 % bedömdes populationen ha viss föryngring. För att musslorna som påträffades skulle räknas som juveniler fick de vara högst 50 mm. Antalet musslor som hittades i provrutorna var 60 varav de flesta påträffades på 100 cm. De flesta juveniler befann sig dock på 60 cm. På 20 cm fanns det inga musslor. Ett överskott på individer i de äldre åldersklasserna kunde ses medan det rådde brist på yngre musslor. Endast 8 % av musslorna var juveniler vilket innebär att det fanns viss föryngring. Risken att musselpopulationen vid Östads badplats ska dö ut är dock ganska stor då reproduktionen är sämre än vad den behöver vara för att musselbeståndet ska vara livskraftigt. De juvenila individer som hittades befann sig i anslutning till de adulta. Att juvenilers habitatval skiljer sig från adulters är alltså inget som kan styrkas av denna studie.

Resumen
Blötdjur (Mollusca) tillhör en av de mest hotade taxonomiska grupperna i världen och musselpopulationer (Bivalvia) har drastiskt setts minska. Den avtagande tillväxten hos musselpoulationen kan bero på faktorer så som minskning av värdfisken, försurning, invasiva arter, föroreningar och igenslamning av bottnar. Alla arter av stormusslor (Unionoida) är känsliga för eutrofiering och fysiska förändringar av deras livsmiljö och kan därmed användas som indikatorer för höga naturvärden eller som indikator på vattnets kemiska kvalitet. För att en musselpopulation skall vara livskraftig krävs en föryngring på mellan 10 till 20 procent. Med föryngring menas andelen juvenila i populationen. I Västra Götalands län visar endast hälften av 33 tidigare  undersökta populationer upp en tillräcklig föryngring. Men när är egentligen musslan juvenil och när övergår den till adult? Idag finns få studier gjorda på stormusslor gällande ålder vid könsmognad. Oftast används uppskattade värden eller andra arters ålder vid könsmognad. Detta arbete syftar till att undersöka tillväxttakten för den allmänna dammusslan. Tillväxten mättes som differenserna av avståndet mellan årsringarna på musselindividernas skal. Med hjälp av den årliga tillväxten kunde en exponentiell tillväxthastighet räknas fram vilken indikerade när tillväxten hos de flesta individer avtog. Brytpunkten som indikerar att tillväxten avtar räknades fram med hjälp av Von Bertalanffys tillväxtmodell som visar tillväxt över tid. Genom att veta i vilken ålder tillväxten avtar kan en slutsats om eventuell könsmognad dras då individen börjar fördela mängden tillgänglig energi till fler funktioner än tillväxt, där reproduktion är den troligaste. Det är viktigt att veta i vilken ålder en art blir könsmogen i bevarandesyfte då en mussla anses vara mycket känslig i sina juvenila år. Resultaten i denna studie visar att tillväxten avtar vid en ålder av 4 år för en av de undersökta sjöarna. I de övriga 2 avtog tillväxten innan musslan uppnåt en ålder av 3 år. Att åldern då tillväxten avtar skiljer sig mellan sjöarna kan bero på att livsförutsättningarna i sjöarna är olika gynnsamma.
Molluscs (Mollusca) belong to one of the most threatened taxonomic groups in the world and mussels (Bivalvia) have been observed to drastically decrease. The reduced growth of the mussel population may depend on factors such as decrease of the host fishes, acidification, invasive species, pollution and siltation of the seabed. All species of large mussels (Unionoida) are sensitive to eutrophication and physical changes in their habitat and can thus be used as indicators of territories with high conservation value or as an indicator of the chemical quality of the water. For a mussel population to be viable it requires a mean the proportion of juveniles (rejuvenation) in the population between 10 to 20 percentages. In Västra Götaland country only half of the previously 33 studied populations show satisfactory rejuvenation. When a mussel is considered to be a juvenile or adult is contentious. Today there are few studies on age at maturity of unionid mussels. Most often estimated values or knowledge of other species age at maturity is used. This work aims to investigate the growth of Anodonta anatina. Growth was measured as the differences in the distance between growth rings on each of the mussel individuals shell. With the annual growth rings an exponential growth rate was calculated that indicated the year in which most of the individuals slowed their growth. The breaking point was found using Von Bertalanffys growth model which indicates growths over time. Knowing the age at which most mussels slows their growth can give us a conclusion of possible age when sexual maturity occurs. The conclusion can be made upon the knowing that an individual starts to allocate the amount of energy available to more features than growth, where reproduction is the most likely. It is important to know the age at which spices reaches sexual maturity due to conservation purposes. A clam is considered very sensitive in its juvenile years. The result in this study shows that growth is slowing at the age of 4 years for one of the studied lakes. In the other two studied, the growth slowed before the mussel attained the age of 3 years. The age at which growth slows differ between lakes and may due to that natural conditions in lakes are various favorable.
