This systematic review and meta-analysis assessed clinical, radiographic and functional retention outcomes in immature necrotic permanent teeth treated either with pulp revascularization or apexification after a minimum of three months to determine which one provides the best results. The literature was screened via PubMed/MEDLINE and Embase databases up to June 2017 to select observational studies that compared pulp revascularization and apexification treatments assessing clinical, radiographic and functional retention outcomes. Two reviewers independently performed screening and evaluation of articles. A total of 231 articles were retrieved from databases, wherein only four articles were selected for full-text analyses. After exclusion criteria, three studies remained in quantitative and qualitative analyses. Pooled-effect estimates were obtained comparing clinical and radiographic outcomes (‘overall outcome’) and functional retention rates between apexification and pulp revascularization treatment. The meta-analysis comparing apexification vs. revascularization for ‘overall outcome’ (Z=0.113, p=0.910, RR=1.009, 95%CI:0.869–1.171) and functional retention rates (Z=1.438, p=0.150, RR=1.069, 95%CI:0.976–1.172) showed no statistically significant differences between the treatments. All studies were classified as high quality. The current literature regarding the clinical, radiographic and functional retention outcomes in immature necrotic permanent teeth treated either with pulp revascularization or apexification is limited. Based on our meta-analysis, the results do not favor one treatment modality over the other.

Background Little is known about fluoride toothpastes effect on primary teeth submitted to erosive tooth wear. Objectives To evaluate the preventive effect of different toothpastes on surface loss (SL) after severe erosion/abrasion model and to compare this effect between permanent (PT) and primary teeth (pt). Design Enamel samples were randomly divided according toothpastes groups (n = 17). G1: placebo; G2: NaF; G3: AmF‐NaF‐SnCl2 anti‐erosion; G4: SnF2; and G5: NaF anti‐erosion for children. Samples were incubated in artificial saliva (1 hour), submitted to erosive challenge (3 minutes; 1% citric acid; pH3.6; at 25°C) and to toothbrush abrasion (2 minutes slurry immersion; 50 strokes; 200 g) during 30 cycles. Surface loss (μm; mean ± SD) was quantified by contactless profilometry. The effects of the two covariables “tooth” and “toothpaste” were analysed by non‐parametric ANOVA, variables with significant effects were tested by Wilcoxon tests. Results pt showed significantly higher surface loss than PT in all groups (P < 0.001). The mean values of SL of each group were: G1 PT 18.18(±3.98), pt 25.65(±9.21); G2 PT 14.76(±2.82), pt 18.11(±3.92); G3 PT 12.62(±5.29), pt 15.61(±6.70); G4 PT 17.12(±2.24), pt 23.41(±7.9); G5 PT 13.24(±1.29), pt 18.28(±8.96). Conclusions In permanent teeth, G3 showed the best preventive effect. In primary teeth, G1, G3, and G5 showed similar effect.

Impact of dental caries, malocclusion and oral habits on the oral health-related quality of life of preschool children Impacto da cárie dentária, maloclusão e hábitos orais na qualidade de vida relacionada à saúde oral em crianças pré-escolares

O presente trabalho avaliou os efeitos de um programa educativo sobre o conhecimento e comportamento de higiene bucal em adultos. Para isso foram selecionados cinqüenta pacientes. No programa aplicado, a educação e motivação foram realizadas através da orientação direta associada aos recursos audiovisuais e à escovação supervisionada. Para a análise do nível de conhecimento, foi aplicado um questionário em três fases, antes do programa, imediatamente após a sua aplicação e seis meses após a sua conclusão. A análise do comportamento de higiene bucal baseou-se na observação clínica dos procedimentos executados pelos pacientes, em duas fases, antes e seis meses após o programa. Os resultados mostram que houve considerável melhora no nível de conhecimento dos pacientes. O nível A passou de 12% antes do programa para 78% após o mesmo, o nível B diminuiu de 84% para 22% e o nível C caiu de 4% para zero. Observou-se também efeito positivo sobre o comportamento de higiene bucal. Antes do programa 36% dos pacientes utilizavam o fio dental de maneira correta e, seis meses após, 74% faziam-no adequadamente. Inicialmente a técnica de escovação de Stillman foi relatada por 40% e na avaliação final por 78%. Quanto à forma de execução da escovação, 28% e 70% realizaram-na corretamente, antes e após o programa, respectivamente. Os resultados obtidos permitem concluir que o programa proposto foi efetivo na melhoria do nível de conhecimento odontológico e comportamento de higiene bucal dos pacientes,mesmo após seis meses da sua aplicação.
