Full textAbstract:
Sclerostin modulation is a novel therapeutic bone regulation strategy. The anti-sclerostin drugs, proposed in medicine for skeletal bone loss may be developed for jaw bone indications in dentistry. Alveolar bone responsible for housing dentition share common bone remodeling mechanisms with skeletal bone. Manipulating alveolar bone turnover can be used as a strategy to treat diseases such as periodontitis, where large bone defects from disease are a surgical treatment challenge and to control tooth position in orthodontic treatment, where moving teeth through bone in the treatment goal. Developing such therapeutics for dentistry is a future line for research and therapy. Furthermore, it underscores the interprofessional relationship that is the future of healthcare.

Full textAbstract:
The mesenchymal stem cells of dental pulp (DPSCs) were isolated and characterized for the first time more than a decade ago as highly clonogenic cells that were able to generate densely calcified colonies. Now, DPSCs are considered to have potential as stem cell source for orthopedic and oral maxillofacial reconstruction, and it has been suggested that they may have applications beyond the scope of the stomatognathic system. To date, most studies have shown that, regardless of their origin in third molars, incisors, or exfoliated deciduous teeth, DPSCs can generate mineralized tissue, an extracellular matrix and structures type dentin, periodontal ligament, and dental pulp, as well as other structures. Different groups worldwide have designed and evaluated new efficient protocols for the isolation, expansion, and maintenance of clinically safe human DPSCs in sufficient numbers for various therapeutics protocols and have discussed the most appropriate route of administration, the possible contraindications to their clinical use, and the parameters to be considered for monitoring their clinical efficacy and proper biological source. At present, DPSC-based therapy is promising but because most of the available evidence was obtained using nonhuman xenotransplants, it is not a mature technology.

In Lake Malawi cichlids, each tooth is replaced in one-for-one fashion every ∼20 to 50 d, and taste buds (TBs) are continuously renewed as in mammals. These structures are colocalized in the fish mouth and throat, from the point of initiation through adulthood. Here, we found that replacement teeth (RT) share a continuous band of epithelium with adjacent TBs and that both organs coexpress stem cell factors in subsets of label-retaining cells. We used RNA-seq to characterize transcriptomes of RT germs and TB-bearing oral epithelium. Analysis revealed differential usage of developmental pathways in RT compared to TB oral epithelia, as well as a repertoire of genome paralogues expressed complimentarily in each organ. Notably, BMP ligands were expressed in RT but excluded from TBs. Morphant fishes bathed in a BMP chemical antagonist exhibited RT with abrogated shh expression in the inner dental epithelium (IDE) and ectopic expression of calb2 (a TB marker) in these very cells. In the mouse, teeth are located on the jaw margin while TBs and other oral papillae are located on the tongue. Previous study reported that tongue intermolar eminence (IE) oral papillae of Follistatin (a BMP antagonist) mouse mutants exhibited dysmorphic invagination. We used these mutants to demonstrate altered transcriptomes and ectopic expression of dental markers in tongue IE. Our results suggest that vertebrate oral epithelium retains inherent plasticity to form tooth and taste-like cell types, mediated by BMP specification of progenitor cells. These findings indicate underappreciated epithelial cell populations with promising potential in bioengineering and dental therapeutics.

This paper reviewed of bruxism phenomenon that refers to the grinding or clenching of the teeth during awake ornight sleep. The prevalence of bruxism decreases with age from 14-18% in childhood, 8% of adult population and3% in the elderly. According to the existing literature, two groups of proposed etiological factors can bedistinguished: peripheral (morphological) and central (pathophysiological and psychological). At present, thebruxism is more often thought to be regulated centrally, not peripherally. Signs and symptoms of bruxism such astooth wear/dental attrition, abfractions, orofacial pain, change of periodontal ligament, mobility, tooth sensitivity,fractured teeth and fillings, earache, headache, tightness of jaw muscle, chewed tissue on the inside of your cheek,impact on the esthetic appearance of a smile. There have been many clinical approaches to the treatment ofbruxism. These can be categorized as acute, preventive and chronic management of bruxism, based on patient’ssigns and symptoms. In the case of acute symptoms with patients experiencing pain, pharmaco-therapeutics may berequired. Meanwhile, if tooth wear is present an occlusal splint and stress management are recommended. Dentistsand health professionals should be aware of increasing the phenomenon of bruxism.

Abstract Background In 2016, an Orange County, California, pediatric dental clinic’s contaminated water system led to the largest outbreak of odontogenic NTM infections yet described. Methods Mandatory reporting and active case finding directed by County Public Health were conducted in collaboration with community Pediatric Infectious Disease physicians for patients who underwent pulpotomy at Dental Clinic A from January 1 to September 6, 2016. Confirmed cases were those with positive NTM culture. Probable cases were those with multiple pulmonary nodules on computed tomography (CT), necrotic bone or osteomyelitis seen at surgery, or pathology with positive acid-fast bacilli stain, granulomatous inflammation or chronic osteomyelitis. Clinical data was collected from medical records. Results Of 1,089 patients at risk, 71 cases (22 (31%) confirmed and 49 (69%) probable) (Figure 1) had been identified as of March 19, 2018 (Figure 2). Median case age was 6 years (range 2–11 years). Symptoms began a median of 85 days (range 1–409 days) after pulpotomy (Figure 3). Pain and/or swelling on admission were reported in 79%; 21% were asymptomatic. CT findings included 49/70 with abnormalities of the mandible or maxilla, 13/70 with lymphadenopathy, and 19/68 with pulmonary nodules. Only 6/60 had erythrocyte sedimentation rate >40 mm/hour. Of 71 cases, 70 were hospitalized and underwent surgical debridement, for an average of 8.5 inpatient days (range 1–60 days); 23 had >1 hospitalization and 26 required >1 inpatient surgery. Permanent teeth were lost in 45/65 (range of 1–6 teeth lost). Intravenous antibiotics were administered to 32 cases for a median length of 137 days (range 113–282 days). Clofazimine was obtained for 29/32 cases as part of the regimen. Medical therapy was complicated by peripherally inserted central catheter malfunction/replacement/infection (18/27), rash (2/27), neutropenia (12/27), and elevated creatinine (7/27). All treated children showed evidence of jaw healing with resolved or improving lung nodules at 1-year follow-up. Conclusion This is the largest outbreak of invasive NTM infections seen associated with a pediatric dental practice. While infections were indolent, patients suffered medical and surgical consequences of treatment. Enhanced national dental water quality standards are needed to prevent future outbreaks.

Full textAbstract:
The GH/IGF axis is a major regulator of bone formation and resorption and is essential to the achievement of normal skeleton growth and homeostasis. Beyond its key role in bone physiology, the GH/IGF axis has also major pleiotropic endocrine and autocrine/paracrine effects on mineralized tissues throughout life. This article aims to review the literature on GH, IGFs, IGF binding proteins, and their respective receptors in dental tissues, both epithelium (enamel) and mesenchyme (dentin, pulp, and tooth-supporting periodontium). The present review re-examines and refines the expression of the elements of the GH/IGF axis in oral tissues and their in vivo and in vitro mechanisms of action in different mineralizing cell types of the dento-alveolar complex including ameloblasts, odontoblasts, pulp cells, cementoblasts, periodontal ligament cells, and jaw osteoblasts focusing on cell-specific activities. Together, these data emphasize the determinant role of the GH/IGF axis in physiological and pathological development, morphometry, and aging of the teeth, the periodontium, and oral bones in humans, rodents, and other vertebrates. These advancements in oral biology have elicited an enormous interest among investigators to translate the fundamental discoveries on the GH/IGF axis into innovative strategies for targeted oral tissue therapies with local treatments, associated or not with materials, for orthodontics and the repair and regeneration of the dento-alveolar complex and oral bones.

Full textAbstract:
Background: Periodontal disease is a chronic inflammatory condition that affects supporting tissues around teeth, resulting in periodontal tissue breakdown. If left untreated, periodontal disease could have serious consequences; this condition is in fact considered as the primary cause of tooth loss. Being highly prevalent among adults, periodontal disease treatment is receiving increased attention from researchers and clinicians. When this condition occurs around dental implants, the disease is termed peri-implantitis. Periodontal regeneration aims at restoring the destroyed attachment apparatus, in order to improve tooth stability and thus reduce disease progression and subsequent periodontal tissue breakdown. Although many biomaterials have been developed to promote periodontal regeneration, they still have their own set of disadvantages. As a result, regenerative medicine has been employed in the periodontal field, not only to overcome the drawbacks of the conventional biomaterials but also to ensure more predictable regenerative outcomes with minimal complications. Regenerative medicine is considered a part of the research field called tissue engineering/regenerative medicine (TE/RM), a translational field combining cell therapy, biomaterial, biomedical engineering and genetics all with the aim to replace and restore tissues or organs to their normal function using in vitro models for in vivo regeneration. In a tissue, cells are responding to different micro-environmental cues and signaling molecules, these biological factors influence cell differentiation, migration and cell responses. A central part of TE/RM therapy is introducing drugs, genetic materials or proteins to induce specific cellular responses in the cells at the site of tissue repair in order to enhance and improve tissue regeneration. In this review, we present the state of art of gene therapy in the applications of periodontal tissue and peri-implant regeneration. Purpose: We aim herein to review the currently available methods for gene therapy, which include the utilization of viral/non-viral vectors and how they might serve as therapeutic potentials in regenerative medicine for periodontal and peri-implant tissues.

AbstractThe objective of this study was to investigate the reproducibility of the International System for the Detection and Evaluation of Caries (ICDAS) for the diagnosis of caries by students of the Master's Degree in Dentistry (n = 25). The occlusal surfaces of human third molars (n = 14) were evaluated by twenty-five (n = 25) students using the ICDAS index and later a questionnaire was applied on demographic and professional context data. The dental crowns were sectioned in mesial to distal direction to obtain slices of 1mm in thickness which were observed in a stereomicroscope (40X) to identify the greatest extension of caries lesion. Data were analyzed by the Chi-Square, Fisher's Exact and Spearman's Correlation Coefficient at a significance level of 5%. There was an influence in the diagnosis of caries among students and teeth, where the majority of those who declared themselves to be safe missed the diagnosis. There was variability between the diagnosis and the proposed treatment for caries, with a better diagnosis for tooth VII and less for X; greater fit for treatment of teeth XIII, XIV and lower for IV, VI. The histological cut showed that the teeth were more affected by caries than the ICDAS. It was concluded that the ICDAS reproducibility was partially satisfactory when the occlusal surface was evaluated by the master’s degree students. Keywords: Dental Caries.

ResumoEste trabalho teve o objetivo de investigar a reprodutibilidade do Sistema Internacional de Detecção e Avaliação de Cárie (ICDAS) para o diagnóstico da cárie, por estudantes de curso de Mestrado em Odontologia (n=25). As superfícies oclusais de terceiros molares humanos (n=14) foram avaliadas por vinte e cinco (n=25) estudantes, utilizando o índice ICDAS, e posteriormente foi aplicado questionário sobre dados demográficos e de contexto profissional. As coroas dentárias foram seccionadas no sentido mésio distal para obter fatias de 1 mm de espessura, que foram observadas em estereomicroscópio (40X) para identificar a maior extensão da lesão de cárie. Os dados foram analisados pelos Testes Qui-Quadrado, Exato de Fisher e Coeficiente de Correlação de Spearman, em nível de significância de 5%. Houve influência do grau de instrução dos estudantes no diagnóstico da cárie em relação ao dente avaliado e a maioria que se declarou segura errou o diagnóstico. Houve variabilidade entre o diagnóstico e o tratamento proposto para a cárie, com maior acerto para diagnóstico do dente VII e menor para o X; maior acerto para tratamento dos dentes XIII, XIV e menor para IV, VI. O corte histológico mostrou que os dentes estavam mais comprometidos pela cárie que o ICDAS. Concluiu-se que a reprodutibilidade do ICDAS foi satisfatória quando a superfície oclusal foi avaliada pelos mestrandos. Palavras-chave: Cárie Dentária. Técnicas e Procedimentos Diagnósticos.

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.

Full textAbstract:
Background: A number of systematic reviews provide the basis for decision-making in treatment planning of the reconstruction of mutilated dentitions. This includes identifying teeth difficult to treat/save and decisions on replacement such teeth if extracted.
Aims:
1) To assess attitudes of general dental practitioners (GDPs) in a community where provision of dental implants is a widely practiced treatment; and to determine variations in attitudes with respect to dentists’ factors, training factors and implant-provision factors (Study 1): and
2) To determine treatment decision making with respect to maintaining periodontally compromised teeth among dentists with and without postgraduate qualifications in implant dentistry (Study 2).
Methods:
Study 1:A cross-sectional survey was conducted on a random sample of registered dentists in Hong Kong regarding their attitudes towards implant dentistry with respect to (1) perceived superiority, (2) perceived outcomes, (3) perceived complications and maintenance issues and (4) placement issues. In addition, information was collected on dentists’ factors, training factors and implant provision factors. Variations in attitudes towards implant dentistry were explored.
Study 2: A series ofpatient scenarios with varying degrees of periodontal disease levels was presented to selected dentists. Information on their decision-making outcomes, and their intention to retain compromised teeth was analysed in bivariate and regression analyses; accounting for postgraduate implant training, gender, years in dental practice and implant placement experience.
Results:
Study 1: Among eligible practitioners (n=246), the response rate was 46.3%. Most dentists’perceived implants to be superior to conventional prostheses for the replacement of a single missing posterior tooth (80%) and likewise, for the replacement of a single missing anterior tooth (67%). Variations in attitudes existed with respect to dentists’ factors: years in practice (p<0.05), place of graduation (p<0.05); implant training factors (p<0.05), number of days of training (p<0.05) and implant experience factors (p<0.05).
Study 2:This study involved 30 dentists with postgraduate implant qualifications (GDPP), 33 dentists without postgraduate implant qualifications (GDP) and 27 dentists undergoing postgraduate training for implant qualifications (GDPT). Variations in treatment decision-making were evident between the three groups (p<0.05). Differences in treatment approaches to retaining compromised teeth were apparent(p<0.05). Furthermore, variations in rehabilitation of extracted scenarios existed in terms of use of implants and number of implants needed for rehabilitation. Accounting for dentist and practice factors in regression analyses, compared to GDP, GDPP/GDPT were three times as likely to retain periodontally compromised upper molars with painwith pain (OR 3.08, 95%CI 1.09, 8.14 p=0.03), or without pain (OR 3.10, 95%CI 1.04, 10.62 p=0.04).
Conclusions:
Study 1:In a community where provision of dental implants is widespread the attitudes of GDPs are not wholly in line with evidence-based knowledge. Variations in their attitudes exist with respect to dentist factors, training and experience issues.
Study 2: Variations in treatment decision making with respect to retaining periodontally compromised teeth exist between dentists with and dentists without postgraduate training in implant dentistry. Furthermore, there are differences in their management approaches.<br>published_or_final_version<br>Dentistry<br>Master<br>Master of Philosophy

Previous issue date: 2005<br>Resumo: O objetivo do presente estudo foi avaliar a ação de uma solução de iodo povidine (PVP-I), associada à raspagem e alisamento radicular, no tratamento de lesões de bifurcação. Foram selecionados 44 pacientes com pelo menos um molar com lesão de bifurcação classe II, em face livre, profundidade de sondagem ³ 5 mm e sangramento à sondagem. Os pacientes foram divididos aleatoriamente em 2 grupos: grupo controle - raspagem e alisamento radicular com ultra-som e água destilada como solução refrigerante; grupo teste - raspagem e alisamento radicular com ultra-som e PVP-I 10% como solução refrigerante. Foram avaliados os seguintes parâmetros clínicos: índice de placa (IP), sangramento à sondagem (SS), posição da margem gengival (PMG), nível clínico de inserção relativo (NICr), profundidade de sondagem (PS) e nível clínico de inserção horizontal relativo (NICHr). A avaliação bioquímica da atividade de enzimas tipo tripsina no biofilme subgengival foi feita pelo teste BAPNA. Os parâmetros descritos acima foram avaliados antes do tratamento, 1, 3 e 6 meses após. Ambos os grupos apresentaram médias semelhantes de redução da PS, ganho de NICr e de NICHr. Aos 6 meses, esses valores foram, respectivamente, 2,31 mm, 1,17 mm e 1,00 mm no grupo controle e 2,31 mm, 1,23 mm e 1,02 mm no grupo teste (p>0,05). Diferença estatisticamente significante também não foi observada entre os grupos quanto ao número de sítios que ganharam 2 mm ou mais de inserção. Aos 6 meses, os grupos controle e teste apresentaram, respectivamente, 45,16% e 30,77% das áreas com ganho de inserção = 2 mm. Na comparação entre os grupos quanto ao SS das lesões de bifurcação aos 6 meses e à quantidade de áreas que exigiram retratamento no 3° mês foi encontrado p=0,06, favorecendo o grupo teste. O teste BAPNA não detectou diferença entre os grupos, entretanto, foi observada diferença intra-grupo, indicando redução na atividade de enzimas do tipo tripsina.

Forty-four patients presenting at least one class II furcation involvement that bled on probing, in bucal or lingual surfaces, with probing pocket depth ³ 5 mm were recruited. Patients were stratified into 2 treatment groups: subgingival instrumentation by an ultrasonic device using PVP-I (10%) as the cooling liquid (test group); identical treatment using distilled water as the cooling liquid (control group). The following clinical outcomes were evaluated: plaque index, bleeding on probing (BOP), position of the gingival margin, relative attachment level (RAL), probing pocket depth (PPD) and relative horizontal attachment level (RHAL). BAPNA test was used to analysis the trypsin-like activity in dental biofilm. The clinical and biochemical parameters were evaluated at baseline and 1, 3 and 6 months after therapy. Both groups had similar means of PPD reduction and RAL and RHAL gain. At 6 months, these variables were, respectively, 2.31 mm, 1.17 mm and 1.00 mm in the control group and 2.31 mm, 1.23 mm and 1.02 mm in the test group (p<0.05). No differences were observed in terms of the frequency distribution of sites demonstrating RAL gain ³ 2 mm. The comparison between groups on BOP of the furcation sites, at 6 months and on the number of sites referred for re-treatment at 3 months showed better values in the test group (p=0.06). The results of BAPNA test failed to demonstrate significant differences between groups.

Full textAbstract:
A radiografia panorâmica e a tomografia computadorizada por feixe cônico (TCFC) são métodos de imagem amplamente utilizados na Odontologia, pois fornecem uma visão geral do complexo dentomaxilofacial, sendo importantes no diagnóstico e tratamento de lesões que acometem esta região. A radiografia panorâmica é considerada um procedimento de baixa dose e a TCFC apresenta doses inferiores quando comparada à tomografia computadorizada (TC). Apesar de baixas, as doses provenientes destes exames expõem órgãos radiossensíveis, como tireoide e glândulas salivares, aos riscos da radiação ionizante. Conhecer os níveis de radiação à que estes órgãos estão expostos é importante para a escolha adequada do método de imagem e parâmetros de exposição a serem utilizados, reduzindo os riscos associados à radiação ionizante, conforme o princípio de radioproteção ALARA (As Low As a Reasonably Achievable - tão baixo quanto razoavelmente exequível). O objetivo deste estudo foi avaliar as doses absorvidas por estes órgãos radiossensíveis durante a realização de radiografias panorâmicas e exames de TCFC, utilizando diferentes parâmetros de exposição. Dosímetros termoluminescentes (TLDs - Thermoluminescent Dosimeters) foram inseridos em um phantom antropomórfico Alderson Radiation Therapy (ART) para identificar as doses absorvidas pela tireoide e glândulas salivares, em um equipamento de radiografia panorâmica e dois equipamentos de TCFC, com diferentes protocolos. As doses absorvidas variaram de 0,01 a 0,22 mGy na tireoide e de 0,26 a 2,96 mGy nas glândulas salivares. Na TCFC as doses variaram de acordo com o protocolo selecionado, porém foram superiores às doses de uma radiografia panorâmica. Os protocolos de TCFC que utilizaram longos tempos de exposição, considerados como protocolos de alta resolução, resultaram em doses superiores quando comparados aos protocolos que utilizaram baixos tempos de exposição. Protocolos que utilizaram campos de visão (FOVs - Fields Of View) maiores, expuseram a tireoide a níveis mais altos de radiação. Diante dos resultados obtidos, pode-se concluir que a TCFC somente deve ser solicitada caso a informação diagnóstica não possa ser obtida através da radiografia panorâmica, sendo a escolha adequada dos fatores técnicos imprescindível para reduzir a dose de radiação durante a realização de exames de TCFC.<br>Panoramic radiograph and cone beam computed tomography (CBCT) are imaging methods widely used in dentistry because they provide an overview of dentomaxillofacial complex, being important in the diagnosis and treatment of lesions that affect this region. Panoramic radiograph is considered a low-dose procedure and CBCT presents lower doses when compared with computed tomography (CT). Although low, the doses from these imaging methods expose radiosensitive organs, such as thyroid and salivary glands, to the risks of ionizing radiation. Knowing the levels of radiation these organs are exposed is important to select the appropiate imaging method and exposure parameters to be used, reducing the risks associated with ionizing radiation, according to the principle of radioprotection ALARA (As Low As a Reasonably Achievable). The aim of this study was to evaluate the absorbed doses by these radiosensitive organs during the course of panoramic radiographs and CBCT examinations, using different exposure parameters. Thermoluminescent dosimeters (TLDs) were inserted into an anthropomorphic phantom Alderson Radiation Therapy (ART) to identify the absorbed doses by the thyroid and salivary glands, in a panoramic x-ray unit and two CBCT units with different protocols. Absorbed doses ranged from 0.01 to 0.22 mGy in the thyroid and 0.26 to 2.96 mGy in the salivary glands. Doses in CBCT varied according to the selected protocol, but were higher than the dose of a panoramic radiograph. The CBCT protocols that used long exposure times, considered as high-resolution protocols, resulted in higher doses compared to protocols that used low exposure times. Protocols that used fields of view (FOVs) higher, exposed the thyroid at higher levels of radiation. Based on the results obtained, it can be concluded that CBCT should only be requested if the diagnostic information can’t be obtained through the panoramic radiograph and the appropriate choice of technical factors essential to reduce the radiation dose during examinations CBCT.

Full textAbstract:
Occlusal splints are used to protect teeth, relieve orofacial pain, and preview the patient response to a simulated occlusal correction. This chapter outlines proper occlusal splint fabrication that employs T-Scan analysis to verify a therapeutic occlusion. The T-Scan provides objective relative occlusal force and timing data that guides the refinement of a splint's occlusal scheme. Therefore, this chapter explains adjusting an occlusal splint's contact pattern with ink ribbon followed by the T-Scan. It also addresses the controversy regarding the existence of, or lack thereof, a relationship between occlusal interferences and masticatory muscle dysfunction. The author postulates that the research studies that argue against the existence of a relationship are absent of occlusal measurement and lack a scientific basis to deny a relationship exists. Lastly, recommendations are made to include the T-Scan in Temporomandibular Disorder treatment studies with both occlusal splints and natural teeth, so that researchers might resolve this controversy for dental clinicians.

Full textAbstract:
Advanced therapies hold substantial promise for the treatment of periodontal conditions. Gene therapy has the potential to transfer “therapeutic” genes, which express proteins such as bone morphogenetic proteins, osteoprotegerin, and tissue nonspecific alkaline phosphatase, which is deficient in patients with hypophosphatasia, a condition that affects mineralization of teeth and bone. Transferred genes may also express platelet-derived growth factor, which modulates the growth of periodontal tissue and the alveolar bone. As regards cell therapy, several clinical trials have shown that mesenchymal stem cells, when used with different kinds of scaffolds to enable the required three-dimensional environment, possess a bone regeneration potential that is particularly useful in such disorders as osteoporosis and osteonecrosis, or for regenerating alveolar bone (osseointegration) prior to placing a dental implant. However, much work is still required before these new therapies become true alternatives in routine clinical dental practice. Medical advances require investments, which are usually influenced by the priorities of both politicians and society at large. This will contribute to promoting innovation, efficient treatments, medium- and long-term savings, and a higher quality of life.

Full textAbstract:
Chapter 4 described caries control measures for everybody, a whole population approach. The emphasis was on oral hygiene, regularly disturbing the biofilm with fluoride toothpaste. The mode of action of fluoride was discussed in some detail to show that this therapeutic agent acts topically to interfere with the deand remineralizing processes and delaying lesion development. The relevance of minimizing sugar intake was discussed. The metabolism of sugar, by microorganisms in the biofilm, creates the acidic environment for demineralization. However, what more should be done for those presenting with active lesions? This chapter will consider how to find out why these patients are developing lesions. The chapter will then explore further oral hygiene measures that might be useful. It will question how fluoride might be boosted and their diet modified. Specific groups, such as babies and young children, those with erupting teeth, patients undergoing orthodontic treatment, and patients with dry mouths will be individually discussed. Finally, a section will discuss the difficulties of advising carers on helping those who can no longer care for themselves, either though illness, disability, old age, or dementia. The caries activity of any patient, child, or adult, is assessed at the first visit of the patient by noting how many lesions judged as active are present (both cavitated and non-cavitated) and where they are located (see Chapter 3). Please note, this assessment is mainly based on clinical assessment. Some companies produce a battery of chairside salivary tests, such as microbiological counts of specific microorganisms, but these are not needed. If the patient is coming for a regular check-up, a history of recent caries activity is available (number of lesions and fillings over the last 1–3 years). This information is most valuable. A yearly increment of one or more lesions detected clinically, would indicate a high rate of lesion formation and progression. Once a dentist has assessed an individual patient’s caries activity as high, an attempt should be made to identify the relevant risk factors for this patient. It is possible to interfere with and modify many of these factors, and thus arrest ongoing active lesions, or slow down the disease activity and diminish the rate of progression.
