RESUMO
OBJECTIVE: This study systematically reviews the evidence on the relationship between sense of coherence (SOC) and oral clinical conditions in adults and elderly people. METHODS: PubMed, Scopus, Web of Science, Latin American and Caribbean Literature in Health Sciences - Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Brazilian Dentistry Bibliography - Bibliografia Brasileira de Odontologia (BBO), Cochrane Library and grey literature were searched. Observational studies involving adults and elderly people that evaluated SOC with a valid instrument and investigated oral clinical measurements as outcomes were included. Two review authors independently assessed the studies for inclusion and extracted data. The quality of studies was assessed using the Downs and Black checklist. Meta-analysis used the random-effect inverse-variance method to obtain pooled odds ratios (OR) and 95% Confidence Intervals (CI) for each oral clinical condition. RESULTS: From a total of 872 identified studies, ten observational cross-sectional and one longitudinal study were included. Nine studies were judged of medium or high risk of bias. Meta-analyses showed that adults and elderly people with higher SOC were less likely to present dental caries (OR 0.84; 95%CI = 0.73-0.96), periodontal disease (OR 0.58; 95%CI = 0.30-0.85), gingivitis (OR 0.54; 95%CI = 0.18-0.90) or dental biofilm (OR 0.65; 95%CI = 0.43-0.86). CONCLUSIONS: Current evidence suggests that better SOC is positively related to better oral clinical status in adults and elderly people. Longitudinal and intervention studies are needed to confirm these findings.

AIM: To evaluate the effectiveness of five instruments used for irrigant agitation during the removal of calcium hydroxide [Ca(OH)2 ] paste in simulated internal root resorption (IRR) cavities created in extracted maxillary central incisors. METHODOLOGY: Seventy maxillary central incisors with a single canal were selected. The canals were accessed and instrumented with Reciproc R50, then the roots were split in the bucco-lingual direction and the halves separated. Simulated IRR cavities were created, in both halves of the roots, 5 mm from the apex with a spherical bur. The specimens were reconstructed with cyanoacrylate glue and allocated into seven groups: negative control - no treatment; positive control - filled with Ca(OH)2 without performing any irrigation protocol; the other groups were divided according to the instrument used for irrigant agitation, namely: Ultrasonic, EndoActivator® , EDDY® , XP-endo® Finisher and XP-endo® Shaper. The specimens were cleaved and analysed using optical microscopy and scanning electron microscopy, to compare the Ca(OH)2 remnants between them. Then, the IRR cavities created by the burs were cleaned and subjected to a protocol of demineralization with 20% nitric acid, the roots reconstructed, and the irrigant agitation methods, as well as the microscopic analysis was repeated. Analysis of the images of Ca(OH)2 remaining in the simulated IRR cavities after irrigation was performed by two calibrated examiners based on a previously established scoring system. The data were statistically compared by Kruskal-Wallis test, Mann-Whitney U-test and Wilcoxon tests, with the significance level set at 5%. RESULTS: There was a significant difference in the effectiveness of the instruments in relation to the cavity creation method (bur vs. bur/acid) and evaluation method (optical microscopy and scanning electron microscopy) (P < 0.05). The XP-endo® Finisher and EDDY® groups were associated with significantly more effective removal of Ca(OH)2 when the IRR cavities were created using the acid protocol and analysed by scanning electron microscopy. CONCLUSION: None of the instruments tested were able to completely remove the Ca(OH)2 paste from the simulated IRR cavities; however, the EDDY® and XP-endo® Finisher removed more Ca(OH)2 in the bur/acid cavity creation method analysed by scanning electron microscopy.

Introduction With the significant increase of women in dentistry, the profile of the dental professional has been altered.Aim To investigate the discourses of future dental surgeons, of both genders, from public and private universities of Curitiba, Paraná, Brazil, to detect whether gender profile differences can influence training and intended future practice.Methods The problem is approached using a qualitative design, with the strategy of collective interviews in focus groups followed by a discourse analysis.Results Women choose dentistry mainly because they like working with people and want to have formal employment in the future. Male discourses show a desire for professional status, worthy business prospects, and the flexibility of being self-employed. The analysis of the university education process revealed that men desire learning that is more technical, besides knowledge on business management, whereas women still complain of current prejudices in the personal relationships that exist with teaching staff and colleagues.Conclusion The teaching process, based on the technique-driven biomedical model, has not reached an ideal standard for the female gender in terms of training, which would be a model based on empathy and good relationships with human beings.
