title: Cephalometric analysis: concordance between software

description: ABSTRACT Objective: To evaluate the agreement between cephalometric measures obtained from two different software programs: Dolphin Imaging 11.7® and Radiocef Studio 2® . Methods: 30 digital lateral teleradiographies (200 dpi, 2100 x 2092 pixels) were analyzed on each of the software programs through demarcation of 11 cephalometric points by a single calibrated examiner. Then, the generated cephalometric magnitudes were statistically correlated by means of the intraclass correlation coefficients (ICC). Then 10 randomly selected radiographies were retraced on each of the programs in order to evaluate the intra-examiner concordance after a time interval of 08 days. Results: The SNB and Pog-NB magnitudes showed strong concordance between the software, while the SNA, ANB, 1-NA, 1-NB, 1.NB, 1.1 and Go-Gn.SN magnitudes unveiled moderate concordance. Only the 1.NA magnitude showed weak concordance. Conclusion: The software can be interchangeably applied in clinical practice.

title: Work process of an oral health team according to the dentists

description: ABSTRACT Objective: The aim of this study, conducted with the participation of the dentists of public service of Campinas, Dental Hygienist Technicians (TSBs) and Oral Health Assistants (ASBs), was to investigate the adequacy of the work process relative to the legal duties and professional limits. Methods: All the 180 dentists linked to the public service in 2014 were invited to take part in the study. Structured and self-administered questionnaires were sent to the these professional and they focused on vocational training and the allocation of functions in routine health care based on the provision of Law 11.889/2008. Results: Considering the respondents, the post-graduation period was 22.1 ± 7.4 years and they had a mean number 16.2 ± 8.9 years of public service. The majority of dentists worked with assistants (82.8%) during the period of study. Regarding the functions delegated to assistants, of the 36 functions identified, it was noted that 14 (38.9%) of the functions delegated diverged from their legal attributes, for most respondents; of these 35.7% (5) denoted extrapolation of ASBs functions, 28.6% (4) extrapolation of TSBs functions and 35.7% (5) underutilization of assistants, in particular TSBs. Conclusion: The authors concluded that most actions were being delegated in a manner consistent with the legal provisions, however, there were still situations of extrapolation of assistant's functions and underutilization of TSBs.

title: Prevalence of dental caries in patients with intellectual disabilities from the Association of Exceptional Children’s Parents and Friends of Southern Brazil

description: ABSTRACT Objective: This study was conducted to determine the prevalence and severity of dental caries, missing and restored teeth (DMFT) and the efficiency of oral health programs for patients with intellectual disabilities, from age 11 to 38, who attended at the Association of Exceptional Children’s Parents and Friends (APAE) in Passo Fundo, southern Brazil. Methods: The prevalence of dental caries was assessed by DMFT in 109 patients. The mean and standard deviation were evaluated by One-way ANOVA with 5% significance level. Results: 47 of the evaluated students were female and 62 male, with moderate mental disability, Down syndrome, cerebral paralysis and epilepsy. The DMFT average was 3.93 for 11-14 years, 3.47 for 15-19 years, 4.74 for 20-30 years and 5.68 for the group 31-40 years. There were no significant differences among the DMFT index, gender and intellectual disability for the groups. Conclusion: Patients had acceptable oral hygiene within their limitations, suggesting that prevention and dental care program developed in APAE-PF/RS could be used as a model for health care for patients with intellectual disabilities in other institutions and other cities.

title: What is the clinical applicability of regenerative therapies in dentistry?

description: ABSTRACT Regenerative therapies have been widely developed in dentistry and it is important to incorporate dentists’ knowledge of these new therapies into the dental clinic routine. This study reviewed the literature on regenerative therapies and clinical applications. Tissue engineering has contributed to changes in the paradigm of restorative health sciences. Its pillars underpin the techniques of tissue and organ regeneration. Despite the majority of studies in this field being in vitro, a range of preclinical studies and methodologies has been formed using these principles and they are already being used on humans. The use of platelet-rich plasma and platelet-rich fibrin in surgery as natural scaffolds for the reestablishment of bone and periodontal tissue are often reported in the literature and clinical trials using this approach have shown promising results. Stem cells from autologous dental pulp have been successfully applied in bone tissue regeneration using natural collagen scaffold in humans. In addition, revascularization of the root canal already appears in the literature as a promising alternative to apexification. The principle behind this therapy is the use of the blood clot as a scaffold and the migration of stem cells of the apical papilla to regenerate the dental pulp organ. Final considerations: Although still in the early stages, regenerative therapies can now be used in dental practice. Knowledge of the principles governing these therapies should be understood by the dentist for use in clinical practice.

title: Effect of CPP-ACP on enamel eroded extrinsically: in vitro study

description: ABSTRACT Objective: The aim of this study was to evaluate the remineralization effect of CPP-ACP on tooth enamel that is eroded extrinsically. Methods: Sixty freshly extracted bovine teeth were stored in a solution of thymol (0.1%), cut into enamel blocks (6x6mm), abraded with silicon carbide sandpaper (600, 800 and 1200 grit) and polished with felt. The specimens were randomly divided into 4 groups (n=15), varying the immersion medium , deionized water or citric acid, and the optional use of CPP-ACP. (G1: deionized water; G2: citric acid; G3: deionized water + CPP-ACP; G4: citric acid + CPP-ACP). The samples were subjected to 4 cycles of erosion every day, comprising 5 minutes immersion in one medium and 2 hours of immersion in artificial saliva, for 5 consecutive days. After each erosive cycle, 20 uL of the MI Paste was applied for 5 minutes on one half of the samples and washed with deionized water. Before and after the erosive cycling, the measurements of Vickers hardness and surface roughness were taken. Results: The results were evaluated through statistical testing. The final hardness and roughness values showed no statistically significant difference between G2 and G4. The paste in G4 did not promote an increase in hardness values nor a decrease in roughness values. Conclusion: It was concluded that CPP-ACP was unable to remineralize enamel subjected to extrinsic erosion, being ineffective in preventing erosion of enamel and in the remineralization of the eroded enamel.

title: Vesiculobullous autoimmune diseases with oral mucosa manifestations: retrospective and follow-up study

description: ABSTRACT Objective: To conduct a retrospective study on a series of cases of PV and BMMP with manifestations in the oral cavity in order to ascertain prevalence, sociodemographic characteristics, diagnostic maneuvers, treatment and follow-up. Methods: This is a retrospective, descriptive study in which clinical data were collected from the medical records of all cases of PV and BMMP registered and diagnosed, between 1995 and 2015, in the Oral Diagnostic Service of the UFRN Department of Dentistry. Results: The mean age of the total sample (n = 36) was 41.64, with females the most frequent (n = 26; 72.22%) and the cheek mucosa being the site most affected (n = 20; 27.40%). Eight patients (22.22%), including 5 cases of PV and 3 BMMP, were clinically reevaluated. All patients exhibited lesions at the time of follow-up. Prednisone (n=7; 87.5%) and clobetasol propionate (n=8, 100%) were the most widely used drugs in the systemic and topical treatment, respectively. The follow-up period ranged from 5 months to 5 years. Conclusion: The clinical profile of patients in this study was similar to that evidenced in the literature. However, it was found that the oral lesions were more resistant to the treatment used on the patients evaluated.
