The scope of this study was to identify the prevalence of oral manifestations in HIV+/AIDS patients at the DIA Pediatric Hospital of Maputo. All 90 patients were included in the research. Data on dental caries (dmft/DMFT index), soft tissues and saliva flow were analyzed. Information on diet and hygienic habits was obtained in a semi-structured questionnaire. The t- student and chi-square tests were used for statistical assessment. The most frequent oral lesion was candidiasis (5.5%) and upon further oral examination the prevalence of parotid enlargement was 23.0%. The mean dmft 2.6 (SD 3.6) was considerably higher in relation to DMFT of 0.6 (SD 1.6), and the differences between them were statistically significant (P<0.05). The occurrence of mucosal lesions was higher in children who did not take antiretroviral therapy (ART) (p = 0.026). The use of ART is associated with reduced prevalence of oral lesions in HIV+ patients; however, rampant caries were highest in this group. Primary dentition of HIV+ patients should be considered high risk for caries.
The aim of this study was to identify the impact of oral disease on the quality of life of morbid obese and normal weight individuals. Cohort was composed of 100 morbid-obese and 50 normal-weight subjects. Dental caries, community periodontal index, gingival bleeding on probing (BOP), calculus, probing pocket depth, clinical attachment level, dental wear, stimulated salivary flow, and salivary pH were used to evaluate oral diseases. Socioeconomic and the oral impacts on daily performances (OIDP) questionnaires showed the quality of life in both groups. Unpaired Student, Fisher’s Exact, Chi-Square, Mann-Whitney, and Multiple Regression tests were used (p<0.05). Obese showed lower socio-economic level than control group, but no differences were found considering OIDP. No significant differences were observed between groups considering the number of absent teeth, bruxism, difficult mastication, calculus, initial caries lesion, and caries. However, saliva flow was low, and the salivary pH was changed in the obese group. Enamel wear was lower and dentine wear was higher in obese. More BOP, insertion loss, and periodontal pocket, especially the deeper ones, were found in obese subjects. The regression model showed gender, smoking, salivary pH, socio-economic level, periodontal pocket, and periodontal insertion loss significantly associated to obesity. However, both OIDP and BOP did not show significant contribution to the model. The quality of life of morbid obese was more negatively influenced by oral disease and socio-economic factors than in normal weight subjects.
The periodontal disease increased in severity and P. gingivalis increased after GBS. A systemic inflammation resolution due to bariatric surgery in obese subjects does not seem to affect the course of periodontal disease.
The established importance of Forensic Dentistry for human identification, mainly when there is little remaining material to perform such identification (e.g., in fires, explosions, decomposing bodies or skeletonized bodies), has led dentists working with forensic investigation to become more familiar with the new molecular biology techniques. The currently available DNA tests have high reliability and are accepted as legal proofs in courts. This article presents a literature review referring to the main studies on Forensic Dentistry that involve the use of DNA for human identification, and makes an overview of the evolution of this technology in the last years, highlighting the importance of molecular biology in forensic sciences.
In published studies, it has been suggested that dental wear is associated with gastroesophageal reflux disease (GERD). This systematic review was carried out to evaluate the association of GERD, dental erosion, and halitosis and to compare the indices adopted in epidemiological surveys. The Medline database (until October, 2011) was searched systematically to identify studies evaluating the prevalence of oral alterations, such as dental erosion and halitosis, in patients with GERD symptoms. Two reviewers analyzed all reports and the selected studies were evaluated according to the quality of evidence, using the validated Newcastle-Ottawa Quality Assessment Scale. Full-text copies of a total of 32 publications were obtained in duplicate. Sixteen publications were identified among the citations in the Bibliographic lists of studies that fulfilled the exclusion/inclusion criteria and quality of evidence. The relationship between dental erosion and GERD patients was significant in only seven studies. According to three studies, halitosis could be one of several extraesophageal symptoms or manifestations in GERD patients. In one study, it was found that the mucosa of GERD patients was significantly more acidic in comparison with that of the control group. This systematic review showed that there is a relationship between GERD and oral diseases (dental erosion and halitosis). The epidemiological surveys used different indices to analyze GERD and dental erosion. Further research could investigate the best method for assessing the two diseases.
Objectives:The aim of this study was to identify the prevalence of dental caries, periodontal diseases and tooth wear in bariatric patients, and relate the oral health conditions to saliva flow.Methods:Fifty-two patients who had undergone bariatric surgery (Roux-en-Y gastric bypass) and 50 severely obese patients indicated for bariatric surgery were submitted to clinical examinations with regard to dental caries (DMFT index), periodontal condition (CPI index), dental wear (DWI index – Dental wear index) and saliva flow. The data were statistically analyzed by the Student’s-t, Mann-Whitney, Spearman Correlation and Chi-square (χ2) tests at 5% significance level.Results:The DMFT index was 16.11±5.19 in the surgical group and 16.06±6.29 in the control group (P>.05). The mean CPI was 3.05±0.84 for the operated group and 2.66±1.25 for the obese patients with no significant difference between them (P>.05). There was statistically significant difference between the groups for the presence of periodontal pockets (P=.021). All the patients presented some degree of tooth wear, however, with no significant difference between the two groups (P=.82). The mean saliva flow values of the surgical group and control group were 0.64±0.46 mL/min and 0.66±0.49 mL/min, respectively. There was no significant difference in saliva flow and all oral conditions analyzed (P>.05).Conclusion:The prevalence of oral diseases was similar in severely obese patients who were candidates for bariatric surgery and in patients who had been submitted to bariatric surgery. Nevertheless, there was higher prevalence of periodontal pockets in the operated group.
ResumoObjetivo: O objetivo deste estudo foi realizar uma revisão sistemática da literatura sobre a associação entre o Diabetes Mellitus e as manifestações bucais. Método: Os métodos aplicados incluíram estratégia de busca na literatura e critérios de inclusão e exclusão para a seleção dos artigos a serem adotados. As bases de dados incluídas foram PubMed, SciElo, BBO e LILACS, até setembro de 2011. Os artigos selecionados investigaram a associação ou não do Diabetes Mellitus com manifestações bucais, excluindo a doença periodontal. Resultado: De 1164 artigos encontrados, 30 deles estavam de acordo com os critérios de inclusão, podendo permanecer no estudo. As manifestações bucais foram associadas com Diabetes Mellitus em 20 estudos. Os desfechos relacionados foram candidíase, hipossalivação, líquen plano bucal, estomatite por dentadura e lesões linguais. Conclusão: Os pacientes portadores de Diabetes Mellitus estão mais predispostos a apresentar candidíase e hipossalivação, podendo agravar muito determinadas condições de saúde bucal. Descritores: Diabetes Mellitus; doenças da boca; manifestações bucais.
