Background We investigated the efficacy of hyperbaric oxygen (HBO), low-intensity laser (LIL), and platelet-rich plasma (PRP) in the management of medication-related osteonecrosis of the jaws (MRONJ). Methods A literature search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Two examiners independently assessed eligibility and risk of bias and extracted data. Results There was improvement in 75.6% of the 41 patients submitted to HBO, with positive effects on pain relief and decreased size and number of lesions at a faster rate, with better effects when the drug was discontinued. For LIL, 158 (64.2%) of the 246 patients/sites improved the symptoms and 98 (39.8%) healed completely. Fourteen (17.3%) of the 81 patients treated with PRP significantly improved the symptoms and 65 (80.2%) completely healed. Conclusions These therapies served as safe and effective adjuvant modalities for MRONJ treatment. The lack of randomized clinical trials evidences the need for more high-quality investigations on the subject.

Objective: The aim of this study was to evaluate the diagnostic capability of dentists in the identification of suggestive images of calcified carotid artery atheroma (CCAA) on panoramic radiographs (PRs) before and after using a problem-based learning method (PBL). Methodology: Five dentists (no specialists in oral and maxillofacial radiology) analyzed 102 digital PRs divided into: PRs with suggestive images of CCAA (n=51) and without suggestive images of CCAA (n=51). After the first analysis, the examiners attended an activity on soft tissue calcifications using the PBL method. Afterwards, they analyzed the 102 PRs again. The results of the analysis were calculated using the Cohen's Kappa Test and the Receptor Operational Characteristic Curves (ROC). Results and Discussion: Regarding examiners’ performance before and after the activity, the intra-examiner test showed reasonable Kappa coefficients (0-0.40). For inter-examiner agreement after the activity, the Kappa coefficient was almost perfect (> 0.80). When comparing examiners’ performance after the activity with a template performed by an experienced radiologist, the Kappa Coefficient was > 0.80 with significant agreement (p 0.80) Al comparar el desempeño de los examinadores después de la actividad con un modelo realizado por un radiólogo experimentado, el coeficiente Kappa fue > 0.80 con concordancia significativa (p 0,80). Ao comparar o desempenho dos examinadores após a atividade com um gabarito realizado por um radiologista experiente, o Coeficiente Kappa foi >0,80 com concordância significativa (p
