O objetivo do presente trabalho foi realizar uma revisão bibliográfica sobre os efeitos que o hábito de fumar pode ter sobre o periodonto e o peri-implante, para alertar a classe odontológica sobre os cuidados que deve pacientes fumantes, bem como contribuir para o esclarecimento da área jurídica, carente desses conhecimentos, na solução dos problemas eventualmente envolvidos na avaliação da responsabilidade civil profissional do cirurgião-dentista. Como decorrência da revisão da literatura e da discussão empreendida, concluiu-se que: o tabagismo tem efeito deletério sobre a saúde bucal, constituindo-se no maior fator de risco para as doenças periodontais conhecido na atualidade; os principais efeitos nocivos do hábito de fumar sobre o periodonto são: diminuição da vascularização, alteração na resposta inflamatória e imunológica, bolsas periodontais mais profundas, maior perda de inserção periodontal e interferência na cicatrização pós-terapias; no que concerne ao peri-implante, o tabagismo provoca: vasoconstrição sistêmica, redução do fluxo sangüíneo, maior probabilidade de desenvolver peri-implantite e interferência na cicatrização pós-cirúrgica; o cirurgião-dentista precisa verificar se o paciente é fumante ou não...

This study presents the findings of a record review that evaluated the prevalence of dental trauma in patients with cerebral palsy and evaluated its possible relationship with age, type of palsy, and epilepsy. The dental records of 2,200 patients with special needs admitted to the special care clinic of the School of Dentistry of Araçatuba/UNESP, Brazil, between 1998 and 2003 were reviewed. Of the records that were analyzed, 500 patients who had cerebral palsy were selected for this study. Information regarding age, gender, type of palsy and dental trauma was collected and statistically analyzed. It was observed that 10.6% of the subjects (n = 53) had sustained dental trauma. The number of traumatized teeth was 84. Enamel or enamel/dentin fractures were the most frequent types of traumatic injury (84.9%). The permanent maxillary central incisors were the most commonly affected teeth (50%). The frequency of traumatic injuries showed no significant correlation (p>.05) with the type of cerebral palsy or gender and they were more frequent in subjects between the ages of 0 and 12 years. Having epilepsy was not a statistically significant risk factor (p>.05) for dental trauma. © 2008 Special Care Dentistry.

Many methods based on biometrics such as fingerprint, face, iris, and retina have been proposed for person identification. However, for deceased individuals, such biometric measurements are not available. In such cases, parts of the human skeleton can be used for identification, such as dental records, thorax, vertebrae, shoulder, and frontal sinus. It has been established in prior investigations that the radiographic pattern of frontal sinus is highly variable and unique for every individual. This has stimulated the proposition of measurements of the frontal sinus pattern, obtained from x-ray films, for skeletal identification. This paper presents a frontal sinus recognition method for human identification based on Image Foresting Transform and shape context. Experimental results (ERR = 5,82%) have shown the effectiveness of the proposed method.

The clinical records correspond to a set of documents where all information of the patient is stored. When properly confectioned and filed by the dentist, it may serve as a tool for success in dental expertise. The aim of this paper is to present the importance of proper confection of dental records in human identification by means the presentation of a case of identification, occurred in a São Paulo state city. The notes present in the dental records of the alleged victim were very poor, even with a contradiction. However, having endodontic treatment been performed, the comparative analysis between the radiographs of the skull of the victim (postmortem) and the endodontic treatment of tooth 22 (antemortem) permitted to observe total coincidence between the details of such treatment, and anatomical features present in other dental elements. These important parameters of comparison indicated that the body was of the suspect and, due to the number of coincidences, it could not belong to another individual. Nevertheless, the clinical documentation provided was deficient, and presented contradictory data. Because of its fundamental importance for human identification, it is essential that dental professionals take the necessary care to ensure its proper confection and custody...

The aim of this study was to radiographically investigate the presence of root canal ramifications found after endodontic treatment, and to determine any relationship between their presence and the type of the auxiliary chemical substance used. The study evaluated 1,470 endodontic treatments performed by final year undergraduate students at the Dental School of Piracicaba, State University of Campinas (UNICAMP), SP, Brazil, during the period from 1998 to 2000. The X-rays taken during treatment were evaluated in order to establish the presence of ramifications of the root canal system. The initial X-ray did not show the presence of any canal ramifications. After filling, X-rays showed only 3 ramification types: 3.06% of lateral canals, 2.99% of apical deltas, and 0.1% of interradicular canals. The maxillary premolars showed the highest number of lateral canals (n = 13), followed by mandibular premolars (n = 10) and maxillary incisors (n = 10). Apical deltas were mostly found in mandibular molars (n = 14), followed by maxillary incisors (n = 9). Only mandibular molars had interradicular canals. The detection of ramifications increased with the use of EDTA. However, no statistically significant relationship was found between the type of auxiliary chemical substance used and the number of root canal ramifications detected after root canal filling. It was concluded that the frequency of root canal ramifications found radiographically was low in treatments performed by undergraduate students.

The aim of this study was to investigate factors associated with caries experience in the primary dentition of one- to five-year-old children with cerebral palsy. A total of 266 dental records were examined, and caries experience was measured by dmft. The following variables were also analyzed: gender, oral hygiene, history of gastroesophageal reflux, use of medications for gastroesophageal reflux, gingival status, sugar intake and reports of polyuria, excessive thirst and xerostomia. For analysis purposes, the individuals were categorized as those with and without caries experience and subcategorized into the following age groups: one year; two to three years; and four to five years. After bivariate analysis, variables with a p-value < 0.25 were selected for incorporation into the Poisson regression models. Considering the limitations of the protocol, the level of oral hygiene perceived on the first appointment was the only factor associated with caries experience among two-to-fiveyear-old children with cerebral palsy.

Having recognized the differences in financial incentives between institutional providers and private practitioners participating in the Medicaid program, the New York State Health Department developed a streamlined mechanism of prior approval for 13 selected institutional providers of dental care. As part of the evaluation of this process, a retrospective audit of 316 dental records was conducted to assess the level of documentation present in the dental record. A followup audit was conducted 3 months after implementation of a plan to correct any deficiencies identified. More than 50 percent of the facilities were unable to present all the records requested at the time of the initial audit. Few of the audited records were free of deficiencies, and documentation of the results of the intra-oral examination was lacking in most facilities. The followup audit demonstrated statistically significant improvement in the level of record documentation. These results demonstrate that, even when good recordkeeping procedures were identified and agreed to by these institutional dental providers, performance was inadequate. However, the study also demonstrates that adequate records can be kept if sufficient incentives are provided. Efforts to evaluate retrospectively the delivery of dental care that are dependent on the dental record as a primary data source are unlikely to succeed unless incentives to encourage good recordkeeping are incorporated. Further research is needed to develop appropriate incentives that would operate in other practice settings.

Dental records consist of documents related to the history of present illness, clinical examination, diagnosis, treatment done, and the prognosis. A thorough knowledge of dental records is essential for the practicing dentist, as it not only has a forensic application, but also a legal implication with respect to insurance and consumerism. This article reviews the importance of dental records in forensics.

4 p. : il., tab.; Epidemiological studies can help in implementing programs to achieve optimal oral health for clefts individuals. The purpose of this study was to identify the dental treatment needs in patients with orofacial clefts in a population from Rio de Janeiro, Brazil. This study analyzed 176 dental records from individuals who born with cleft lip and palate, aged varied 0-61years, which receiving assessment at a public hospital reference of cleft rehabilitation, between 2006 to 2008. Chi-square test at a level of significance of 0.05 was used. Analysis enrolled 169 dental records after exclusion of seven dental records due to incomplete data. The sample consisted of 84 female and 85 male. The mean age was 19.7(±5.8). Forty patients had cleft lip(CL), 87 had cleft lip and palate(CLP) and 42 had cleft palate(CP). The majority of patients (85.2%) required invasive dental treatment needs, such as, restorative treatment, endodontic treatment, dental extraction and periodontal treatment. Patients with CLP presented a positive association with untreated dental caries than CL and CP (p=0.03). CLP patients were strongly associated with orthodontic treatment need when compared with CL and CP (p<0.05). We identified an extensive dental treatment needed in patients with CLP. A developing of an oral health programs is recommended for CLP individuals in this region.

Aim: Determine the prevalence of dental injuries (TDI) in primary teeth and the influence of predisposing clinical factors on their occurrence and analyze the prevalence of developmental sequelae in permanent teeth and determine the association between these sequelae and age, gender, injury type, injury recurrence and sequelae in primary teeth, in children under 7 years old who sought treatment at a private pediatric dental clinic in Goiânia, Goiás, over a period of 15 years. Methodology: A retrospective study which analyzed 2725 dental records. Three hundred and eight dental records with 412 traumatized primary teeth were selected. This constituted the sample used to determine the prevalence of injuries in primary teeth and their association with predisposing clinical factors (Article 1); of these, 241 primary teeth (148 dental records) were followed up until the eruption of the permanent successor teeth. This was the sample for the study of sequelae in primary and permanent teeth (Article 2). All the data were statistically analyzed using the frequency distribution, chi-square test and logistic regression analysis. The level of significance was 5%. Results: The prevalence of dental injuries was 11.3%, with the greatest frequency in the 13-36 month age group. There was no statistical difference between genders. The most frequently affected teeth were the maxillary central incisors (83.3%). The main location of inuries was the home (43.5%)...

Background: Pulp stones are discrete calcified bodies found in the dental pulp. The aims of this study were to calculate the prevalence of pulp stones in young Australian adults using radiographs, and to report any associations between occurrence of pulp stones and sex, tooth type, dental arch, side and dental status. Methods: From 217 undergraduate dental students, comprising 123 males and 94 females aged between 17-35 years, 3296 teeth were examined under 2x magnification on bitewing radiographs. Pulp stones were scored as present or absent, and associations with sex, tooth type, dental arch, side and dental status noted. Results: Pulp stones were found in 100 (46.1 per cent) of the subjects and 333 (10.1 per cent) of the teeth examined. Occurrences were rare in premolars (0.4 per cent) but significantly higher in molars (19.7 per cent). Pulp stones were significantly more common in first molars than in second molars, and in maxillary first molars than in mandibular first molars. Carious and/or restored maxillary right first molars and maxillary left second molars displayed higher prevalences of pulp stones than unrestored and intact molars. Conclusion: Pulp stones may provide useful forensic information when examining dental records to identify deceased persons.; S Ranjitkar...

Background: Comparisons between monozygotic (MZ) co-twins have tended to focus on the similarities between their dentitions rather than differences. The aim of this study was to determine the prevalence of discordant expression for simple hypodontia and supernumerary teeth in MZ twin pairs and to explain how phenotypic differences might occur despite their similar genotypes. Methods: Records of 278 pairs of MZ twins, including dental casts and radiographs, were examined and the prevalences of discordant expression for missing upper lateral incisors (ULI) or second premolars (PM2), and of mesiodentes, were determined. Zygosities were confirmed by comparisons of blood markers and DNA. Results: There was evidence of at least one missing ULI or PM2 in 24 of the 278 MZ pairs (8.6 per cent), with 21 of these 24 pairs (87.5 per cent) showing discordant expression. Nine of the 278 MZ pairs (3.2 per cent) displayed evidence of mesiodentes, with eight of these nine pairs (88.9 per cent) being discordant. Conclusion: Our findings show that differences in the expression of missing or extra teeth occur often between MZ co-twins whose genetic make-up predisposes them to simple hypodontia or mesiodentes. We postulate that minor variations in epigenetic events during odontogenesis may account for these distinct differences.; GC Townsend...

Background: Longitudinal patterns of public dental service use may reflect access issues to public dental care services. Therefore, patterns of dental service use among South Australian adult public dental patients over a 3½-year period were examined. Methods: Public dental patients (n = 898) initially receiving a course of emergency dental care (EDC) or general dental care (GDC) at baseline were followed for up to 3½ years. Patient clinical records were accessed electronically to obtain information on dental visits and treatment received at those visits. Results: Some 70.7 per cent of EDC and 51.3 per cent of GDC patients returned for dental treatment post-baseline. EDC patients returned within a significantly shorter time period post-baseline, received significantly more courses of care and were visiting more frequently than GDC patients. A greater proportion of EDC patients received oral surgery, restorative, endodontic and prosthodontic services, but fewer received periodontic services. EDC patients received significantly more oral surgery and fewer preventive services per follow-up year, on average, than GDC patients. Large proportions of EDC (52.4 per cent) and GDC (63.8 per cent) patients who returned sought emergency care post-baseline. Conclusions: Patients appeared to be cycling through emergency dental care because of lack of access to general care services...

Background: Conditions in utero and early life underlie risk for several childhood disorders. This study tested the hypothesis that the Apgar score predicted dental caries in the primary dentition. Methods: A retrospective cohort study conducted in 2003 examined associations between conditions at birth and early life with dental caries experience at five years. Dental examination data for a random sample of five-year-old South Australian children were obtained from School Dental Service electronic records. A questionnaire mailed to the parents obtained information about neonatal status at delivery (five-minute Apgar score, birthweight, plurality, gestational age) and details about birth order, weaning, and behavioural, familial and sociodemographic characteristics. Results: Of the 1398 sampled children with a completed questionnaire (response rate = 64.6%), 1058 were singleton term deliveries among whom prevalence of dental caries was 40.1%. In weighted log-binomial regression analysis, children with an Apgar score of <=8 relative to a score of 9–10 had greater probability of dental caries in the primary dentition after adjusting for sociodemographic and behavioural covariates and water fluoridation concentration (adjusted PR = 1.47...

Approved for public release; distribution is unlimited.; All Naval dental treatment facilities (DTF) worldwide are required to submit monthly reports containing dental records of treatments provided and overall dental readiness to COMNAVMEDCOM, in Washington, D.C. These reporting requirements are standardized to meet not only the requirements of the Navy, but also as input to the DOD mandated Medical Expense and Performance System (MEPERS). At many commands, this data collection storage and reporting effort is currently performed manually, adding unnecessary additional administrative burden. This thesis develops a computerized database system providing increased accuracy and productivity, and capable of meeting the NAVMED reporting requirements. The Dental Information Retrieval System (DIRS) developed will record all treatments provided for each beneficiary category described in NAVMEDCOMINST 6600.1B, and will facilitate internal external daily, weekly, monthly and annual reporting requirements. An important design consideration is providing the DIRS developed with the requisite capabilities specified by the DTF's, without imposing additional hardware requirements. NAVDENCLINIC Long Beach, CA>, is the sponsoring activity for DIRS, and will serve as the test sited for system implementation. If the system is successful...

The use of fluoride involves a balance between the protective effect against caries and the risk of having fluorosis. Fluorosis in Australian children was highly prevalent in the early 1990s. Policy initiatives were introduced to control fluoride exposure so as to reduce the prevalence of fluorosis. Objective: The study aimed of describing the prevalence, severity and risk factors for fluorosis, and to escribe the trend of fluorosis among South Australian children. The study also aimed of exploring the effect of the change in fluoride exposure on dental fluorosis and caries. Methods This research project was nested in a larger population-based study, the Child Oral Health Study (COHS) in Australia 2002-2005. The parent study's sample was chosen using a multistage, stratified random selection with probability of selection proportional to population size. Fluoride exposure history was retrospectively collected by a parental questionnaire. This nested study sample (n=1401) was selected from the pool of South Australian (SA) COHS participants. Children were selected by year of birth to form three birth cohorts: those born in 1989/90; 1991/92; and 1993/94. Children were approached in two further stages: a dental health perception questionnaire...

Background There is limited evidence of the influence of psychosocial factors and health beliefs on public dental patient's patterns of service use in Australia. The research aims were to examine associations between dental attitudes and beliefs of public dental service users and dental visiting intention and behaviour using the Theory of Planned Behaviour. Methods 517 randomly selected adult public dental patients completed a questionnaire assessing dental attitudes and beliefs which was matched with electronic records for past and future dental service use. A questionnaire measured intentions, attitudes, subjective norms and perceptions of behavioural control and self-efficacy in relation to visiting public dentists. A measure of dental attendance at public dental clinics was obtained retrospectively (over 3 1/2 years) and prospectively (over a one year period following the return of the questionnaire) by accessing electronic patient clinical records. Results Participants had positive attitudes, subjective norms and self-efficacy beliefs towards dental visiting but perceived a lack of control over visiting the dentist. Attitudes, subjective norms, self-efficacy and perceived control were significant predictors of intention (P < 0.05). Intentions...

BACKGROUND: Forensic odontologists provide an important service to the community by identifying unknown deceased people, allowing both legal outcomes and family closure. Non-visual identification may be achieved by comparison of post-mortem data with ante-mortem dental records provided by oral health practitioners. Success is dependent largely on the accuracy and adequacy of data in the dental records. METHODS: An online self-administered questionnaire evaluated Australian dentists' knowledge and behaviours relevant to forensic odontology. Reported record keeping practices were assessed for detail, legibility, accessibility and retention. Behaviours were classified according to the frequency of response. RESULTS: Dentists reported overall reasonable awareness of the major applications of forensic odontology. Personal information and details of restorative treatment were recorded at high levels, while tooth anomalies, photography, additional patient details and denture marking were recorded inadequately. Legible tooth coding was reported at a high level, while other key legibility practices were recorded inadequately. Few of the behaviours related to retention or to maximise accessibility were recorded at a high level. CONCLUSIONS: Australian dentists have high expectations of the forensic value of their dental records; however many practices that would enhance the diagnostic...

Dental records are essential for dentist and patient protection, and its maintenance is considered an ethical and legal obligation of the dentist: Ethical, because it satisfies the duty of care that the dentist has toward his patient and legal, as it is an investment for future protection against medico-legal complications. In addition to its legal and ethical role, the dental fraternity in India is slowly waking up to its importance in forensic dentistry. Dentists could play a vital role in assisting forensic investigators in providing information that would help in the identification of perpetrators or victims of crime and natural or manmade disaster situations. This information would be easily available and accessible through well-maintained patient records under dental care.
