title: Spatial distribuition of tooth loss in a population of adults

description: ABSTRACT Introduction: Although there has been an improvement in the oral health status of the population, tooth loss still aggravates the oral health of adults and is a matter of great relevance to dentistry. Aim: To determine the spatial distribution of tooth loss in adults and correlate this with the Social Exclusion Index and proximity to public dental services. Material and Method: This ecological study was based on epidemiological data of adults from Piracicaba municipality and from the Piracicaba Research and Planning Institute (IPPLAP). Data on dental evaluations were extracted from the Piracicaba epidemiological survey, which was a cross-sectional study with probabilistic sampling of 248 adults aged 20-64 years, representative of adults living in Piracicaba, Brazil. Oral examinations of the DMFT index were in accordance with the World Health Organization codes and criteria and were performed by a single examiner calibrated for this purpose. Data on social exclusion and the municipal health units that have dental services were extracted from IPPLAP. Georeferencing was performed of census tracts selected by draw, and the city health facilities that have dental services. For Spearman correlation analysis (p &lt;0.05), we used the mean value of teeth lost per district, the Social Exclusion Index (IEX), and proximity to public dental service categorized according to radius: &lt;500m, between 500-1000m, and &gt;1000m the census tract. Result: There was a correlation between tooth loss and higher IEX, and r=−0.51 (p=0.01), but no correlation with proximity to public dental services (p=0.42). Conclusion: Tooth loss in adults was distributed according to social exclusion, however, it was unrelated to proximity to the public dental services.

title: The clinical prevalence of actinic cheilitis among community health agents from the regional V subprefecture of Fortaleza

description: ABSTRACT Objective: The aim of this study was to evaluate clinically the prevalence of Actinic Cheilitis in community health agents from the Regional V subprefecture of Fortaleza. Methods: The sample consisted of 333 community health workers exposed to the sun on a daily basis. The community health agents were evaluated through a questionnaire (with information about the individual, their occupations and habits) and a clinical examination in the first stage of the study. In the second stage, the Actinic Cheilitis lesions were classified according to the degree of severity, monitored and treated as needed. Both stages were performed by just one examiner. The data were tabulated in an Excel spreadsheet and evaluated by means of the G-test. Results: The results showed that the prevalence of Actinic Cheilitis was significantly associated with age, race / color and use of lip balm. A total of 101 (30.3%) community health agents were found to have normal labial mucosa, 195 (58.5%) had a mild alteration in Actinic Cheilitis, 34 (10.2%) with moderate Actinic Cheilitis and in 3 (0.9%) severe change was identified. Conclusion: The study concluded that the prevalence of Actinic Cheilitis is high among the community health agents from the Regional V subprefecture of Fortaleza.

title: Incidental findings in patients evaluated with cone beam computed tomography for orthodontic treatment

description: ABSTRACT Objective: The aim of this retrospective study was to determine and quantify incidental findings in CBCT scans taken exclusively for orthodontic purposes. Methods: A total of 202 scans were evaluated by two examiners and classified into five different groups. Results: A total of 227 incidental findings were found in a sample of patients aged 5-58 years old. The highest number of findings was of dental origin (n = 157), followed by airway (N = 46), skull (N = 16) and ATM (n = 8). Scans with no incidental finding accounted for 20% of the examinations. Subjects having lower mean age were found in the group of airway findings. The prevalence of incidental findings in the current study was consistent with the literature, thus corroborating their high frequency. Orthodontists who make use of CBCT are responsible for assessment of all data. Conclusion: The precise evaluation of incidental findings may help in the early diagnosis, treatment and patient monitoring. Further studies should be conducted to assess the influence of these findings on the orthodontic treatment.

title: Oral hygiene, dietary habits and prevalence of dental caries in adolescents from rural and urban areas in Rio Grande do Sul, Brazil

description: ABSTRACT Objective: To determine the condition of oral hygiene, dietary habits and prevalence of dental caries in adolescents, listing these habits and comparing residents from rural and urban areas. Methods: Cross-sectional study involving of 623 adolescents of both sexes, aged 12 to 17 year old in Santa Cruz do Sul, Brazil. Data were collected through sociodemographic questionnaires and dental examination. We conducted a descriptive analysis of the exposure variables and outcome. A bivariate analysis was then performed using the Chi-square test. Results: The prevalence of caries was 63.6%, in which adolescents living in rural areas had a prevalence of 70.7% and 56.4% in the urban area. The level of mother’s education ≤4 years and socioeconomic class B1/B2 and C1/C2 showed statistically significant differences between the areas of residence. Among the demographic variables, the rural area showed a higher prevalence of caries. Conclusion: The results showed a high prevalence of dental caries among the adolescents studied and indicate a correlation between prevalence and the low level of mother’s education, socioeconomic status (low to medium) and residence in rural areas. It should be understood that, while the multifactorial nature and stratified caries actions are not taken into consideration, the actions implemented will continue to fail, frustrating the expectations set by government entities.

title: The impact of hospitalization on periodontal health status: an observational study

description: ABSTRACT Objective To evaluate the impact of hospitalization on the periodontal status of patients admitted to a private hospital. Methods A sample of 41 patients answered a questionnaire on oral hygiene habits before and after hospitalization. An examiner measured the Periodontal Screening and Recording ratio (PSR) within 24 hours after hospitalization (T0), after five (T1) and after ten days of hospital admission (T2). Results 47 patients were examined at T0, 37 at T1 and 21 at T2. Between T0 and T1, the periodontal condition of 32.4% of patients worsened (p = 0.001). The score of ten patients changed from PSR = 0 to PSR = 1 and the score of two changed from PSR = 1 to PSR = 2, after 5 days of hospitalization. At T2, 38% of patients had deteriorated (p = 0.005) with 4 developing gingival bleeding and 4 presenting calculus. 19% of patients (p=0.046) declined between T1 and T2, and 4 patients presented calculus. None of the patients received any guidance on oral hygiene by hospital staff. Conclusion The periodontal condition of hospitalized patients deteriorated over the course of the stay in hospital and, consequently, there was an increased need for treatment. This draws attention to the importance of oral hygiene care in hospital.

title: Monostotic fibrous dysplasia: a case report with cone-beam computed tomography findings

description: ABSTRACT Fibrous dysplasia is a benign fibrous-osseous lesion in which normal bone is replaced by fibrous connective tissue and immature bone, affecting only one (monostotic) or several bones (polyostotic) and mainly occurring in children and young adults. When present in facial bones, the maxilla is more frequently involved than the mandible, which can cause facial asymmetry in addition to dental complications. In the image exams, the main characteristic of fibrous dysplasia is its unpolished glass appearance. Computed tomography is the ideal method for evaluating this lesion and its relationship with adjacent structures. The use of conventional radiography, due to the overlapping of anatomical structures, makes it difficult to delineate the extension of the lesion. The present study is aimed at guiding dentist-surgeons on the main imaging characteristics of fibrous dysplasia by describing a case of a female 10-year-old patient presenting with this lesion in the maxilla.

title: Smoking, alcohol consumption and oral cancer among healthcare academics

description: ABSTRACT Objective To evaluate if dental students with the habit of smoking exhibit alterations in the epithelial cells of the cheek mucosa on the nuclear area (NA), cytoplasmic area (CA) or in the nucleus/cytoplasm ratio (NA/CA), when compared to non-smokers. Methods This is a descriptive, experimental study using a control group. The sample comprised 40 dental undergraduates (20 smokers and 20 non-smokers). Individuals who smoked at least 5 or 6 cigarettes a day were deemed to be smokers, while non-smokers were those who reported having no experience of any form of smoking. The samples of epithelial cells were obtained from the oral mucosa using the liquid-based exfoliative cytology technique. The slides were processed in the laboratory, stained using the Papanicolau technique and were analyzed via an image analysis system (analySIS getIT). A structured questionnaire was applied with the aim of measuring independent variables related to personal characteristics, health and lifestyle behavior. Results The values obtained in the group of smokers were as follows: NA (169.4 µm² ± 17.0), CA (1240.1 µm² ± 128.9) and NA/CA ratio (0.1375 ± 0.01743). The results did not evidence significant differences when compared to the control group: NA (170.7 µm² ± 20.0), CA (1255.3 µm² ± 174.5) and NA/CA (0.1380 ± 0.01436). Conclusion It was not possible to observe significant cell alterations in the NA, CA or the NA/CA ratio of epithelial cells of the oral mucosa. Other risk factors associated with tobacco should be studied, principally the length of exposure to the properties of the causative agent.

title: Mesenchymal stem cells in periodontics: new perspectives

description: ABSTRACT Tissue engineering is a contemporary field of science, which aims to create conditions based on principles of cell and molecular biology, bioengineering and biomaterials to regenerate tissues. Mesenchymal stem cells present high proliferation rates and are able to differentiate into multilineages under certain conditions, suggesting that they have great potential to act in regeneration field. Tooth derived stem cells are a suitable alternative source of mesenchymal cells once they are easily accessible and have poor morbidity to the donor. Studies showed that they have been isolated and characterized from diverse tissues such as dental pulp, exfoliated deciduous teeth, periodontal ligament, gingiva, dental follicle and apical papilla. However studies show that there is heterogeneity among these populations and there is no standard method to select the most appropriate tooth derived stem cells for regenerative procedures. The aim of this review is to present the current perspective of the multiple types of tooth-derived stem cells and to discuss the basis for their use in periodontal tissue engineering.

title: Dental trauma in contact sports

description: ABSTRACT Objective Investigate the prevalence of dental traumas in participants of two contact sports (Judo and Taekwondo) and characterise some related factors. Methods Cross-sectional pilot study of observational nature, conducted by observing and collecting data and information. The sample consisted of 60 individuals of both genders aged between 5 and 15 years old, participants of Judo or Taekwondo. The statistical analysis involved descriptive and inferential statistical measures. Results The prevalence of dental trauma in the studied sample was of 38,3%, with the majority occurring outside the practice of sport (82,6%). Only 4 children suffered trauma whilst playing their sport, corresponding to a prevalence of 6,67%. In addition, all 4 cases pertained to the practice of Judo. The most affected teeth were the primary maxillary central incisors followed by the permanent maxillary central incisors, with only one injured tooth in most cases. The lips were the soft tissue with greatest number of registered traumatic lesions. A statistically significant relationship was observed between risk factors and the occurrence of trauma. Conclusion A high prevalence of dental trauma in the studied population was found. Despite no record of traumatic lesions in Taekwondo, this prevalence was particularly noticeable in Judo.
