Chlorhexidine mouthwash as an anticaries agent: A systematic review.

OBJECTIVE: To evaluate the effectiveness of chlorhexidine mouthwashes on the reduction of cariogenic bacteria on patients with moderate to high risk for dental caries. DATA SOURCES: A systematic review of the literature was performed using Cochrane Library, Embase, PubMed, Scopus and Web of Science. The search was limited to articles in English, Spanish, and Portuguese, published until January 2017. The research question was formulated following the PICO strategy. The risk of bias was evaluated using the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. CONCLUSION: All the authors found statistically significant differences in Streptococcus mutans levels during and after the use of a chlorhexidine mouthwash. Although the results are suggestive, there is a clear need for the development of new studies with higher quality and with longer follow-ups, in order to assess whether the results translate into less development of dental caries and, consequently, whether or not these products should be incorporated into prevention protocols.

Therapies for White Spot Lesions-A Systematic Review.

INTRODUCTION: The first sign of dental caries is denoted by white spot lesions (WSLs) which can be defined as a demineralization of the enamel surface and subsurface, although these lesions can be reversed and do not form cavities. The aim of this systematic review was investigate which remineralization agents are effective for the treatment of WSLs. MATERIALS AND METHODS: For this systematic review a literature search was conducted on Pubmed, Cochrane Library and ScienceDirect. RESULTS: The initial search resulted in 273 references. After elimination of duplicate articles, 236 references remained. After reading titles and abstracts, all non-relevant results were excluded, resulting in 45 potentially relevant studies. After reading the full text, 13 references were included. CONCLUSION: More studies are required for scientific evidence in order to reach a conclusion of the most suitable therapeutic method for the treatment of surface and subsurface demineralization of the enamel.

Portuguese Dentists' Attitudes Towards Their Role in Addressing Obesity.

PURPOSE: To determine Portuguese dentists' role in addressing obesity. MATERIALS AND METHODS: For this pilot study, the original version of the Dentists' Role In Addressing Obesity questionnaire was translated from English into Portuguese and validated to ensure that it was culturally adapted for Portuguese dentists. The questionnaire was distributed to a random sample of 400 Portuguese dentists. SPSS Statistics 20 was used to analyse the survey sampling design and assess respondents' attitudes and opinions, outcome expectations and self-efficacy both as ordinal and dichotomised variables. The analysis was a descriptive statistic based on frequencies, without symmetry test. RESULTS: In all, 141 dentists responded. Overall, 22.0% of respondents offered a form of counseling services and 58.9% reported that they were interested in offering obesity-related services. A paucity of trained personnel (58.9%) was cited by the respondents as a major barrier, followed by patients' rejection of weight-loss advice (32.6%) and fears of offending patients (29.1%). 92% of respondents agreed that dentists would be more willing to intervene if obesity were linked to oral disease. CONCLUSION: Healthcare providers must coordinate prevention and interventional efforts for maximum effect. Given the positioning of dentists willing to assist in such an effort, it appears reasonable for experts in obesity intervention in conjunction with dental educators to develop intervention models to be implemented within the scope of the dental practice.
