Ineffectiveness of ozone therapy in nonsurgical periodontal treatment: a systematic review and metaanalysis of randomized clinical trials

Objective: This systematic review (SR) aimed at assessing the adjunctive clinical effect of ozone therapy (OT) on nonsurgical periodontal treatment. Materials and methods: Articles published prior to September 2019 were electronically searched in four databases without any other date or language restrictions and manually searched in regular journals and in gray literature. This review was performed according to the PICO format. The eligibility criteria comprised randomized controlled trials (RCTs) that analyzed the adjunctive effect of OT on nonsurgical periodontal treatment. Results: Twelve studies published between 2010 and 2019 were included in this SR. A metaanalysis of ten reports showed that there was no statistically significant difference in the periodontal parameters analyzed when scaling and root planing (SRP) plus sulcus irrigation with ozonated water or sulcus insertion of ozonated gas were used when compared to SRP alone. Additionally, there was no significant difference when the effect of SRP plus ozonated water was compared with SRP plus 2% chlorhexidine gluconate (CLX). No studies reported significant microbiological differences when the use of ozone was compared with SRP alone. Conclusions: The results of this SR do not support the use of OT for nonsurgical periodontal treatment. However, due to the potential heterogeneity across the studies, the presence of confounding factors, and the short follow-up of some included RCTs, these results should not be considered definitive. Clinical relevance: The current evidence indicates that ozone has antimicrobial activity and good biocompatibility with periodontal cells and gingival fibroblasts. However, no evidence was found for a positive effect of OT as an adjunct to scaling and root planing.No Full Tex

Saúde bucal no contexto do Programa Saúde da Família: práticas de prevenção orientadas ao indivíduo e ao coletivo Oral health in the context of the Family Health Program: preventive practices targeting individual and public health

As práticas profissionais refletem a estruturação dos serviços de saúde, relacionando-se aos princípios norteadores do modelo de atenção vigente. Nesse sentido, objetivou-se conhecer as práticas preventivas e educativas em saúde bucal realizadas pelos dentistas do Programa Saúde da Família de Natal, Rio Grande do Norte, Brasil. Realizou-se entrevista estruturada com 80 dentistas e análise documental no SIA-SUS (Sistema de Informações Ambulatoriais do SUS) e no Sistema de Informação de Atenção Básica. As atividades individuais de orientação de higiene bucal e de aplicação tópica de flúor, entre todos os entrevistados, corresponderam a 87,5% e 95%, respectivamente. Em âmbito coletivo, todos que atuavam nas escolas (91,2%) realizavam aplicação tópica de flúor, enquanto 86,2% desenvolviam ações educativas. Nos registros do SIA-SUS, as atividades preventivas representaram 41% do total de procedimentos. Dentre essas, aplicação tópica de flúor gel por sessão correspondeu a 24,4% e escovação supervisionada, a 31%. Quanto às atividades educativas, 57,4% realizaram-se no estabelecimento de saúde e 42,6%, na comunidade. Diante dos resultados, constatou-se que as práticas preventivas direcionam-se à cárie dentária, com maior atenção aos escolares, sendo necessária ampliação para diferentes problemas bucais, grupos e espaços sociais.<br>Professional practices reflect the structuring of health services and are related to the underlying principles of the prevailing health care model. This study focused on preventive and educational practices by dentists in the Family Health Program in Natal, Rio Grande do Norte State, Brazil. A structured interview was held with 80 dentists, in addition to analysis of documents from the Outpatient Database of the Unified National Health System (SIA-SUS) and the Primary Care Database. Individual activities involving orientation for oral hygiene and topical application of fluoride were reported by 87.5% and 95% of dentists, respectively. At the collective level, all the dentists that worked in schools (91.2%) performed topical fluoride application, while 86.2% conducted educational activities. According to SIA-SUS records, preventive activities accounted for 41% of all procedures. Among these, topical application of fluoride gel per sitting and supervised brushing accounted for 24.4% and 31%, respectively. As for educational activities, 57.4% were held in the health care unit and 42.6% in the community. The findings indicate that the preventive practices focus on dental caries, particularly in schoolchildren, and that they need to be expanded to include other oral health problems
