Retention of resin‐based pit and fissure sealants: a systematic review

Abstract

The aim of the present study was to perform a systematic review on the retention of resin-based sealants (RBSs) according to the material used and the clinical procedure. An electronic search in MEDLINE, EMBASE, Cochrane library and SCOPUS was completed by a hand search in conference proceedings. One hundred and twenty-four studies were identified, 31 of which were included. The retention rate of auto-polymerized and light-cured RBSs did not differ significantly. Light-cured RBSs had a significantly higher retention rate than fluoride-containing light-cured RBSs at 48 months (RR = 0.80, 95% CI: 0.72-0.89) and more. Concerning the clinical procedure, the scarcity of well-conducted studies made judgement difficult, except for the isolation stage. If using a rubber dam did not affect retention of auto-polymerized RBSs, it did for fluoride-containing light-cured RBSs (RR = 2.03, 95% CI: 1.51-2.73).

Wear and morphology of infiltrated white spot lesions

“…Nonetheless, success in a sealing protocol is highly dependent on the retention of the sealant, which has reportedly been high in prospective clinical trials for pit and fissure sealants. 14,[41][42][43] Macroscopic voids, as shown in the investigated bovine enamel substrates, might arise from natural enamel cracks that are present in bovine as well as in human enamel. However, the artificial demineralisation process using the Buskes solution might preferably demineralise along those enamel ''pre-cracks'', thereby creating larger voids.…”

A System of Calibrating Microtomography for Use in Caries Research

“…Delton (Dentsply Professional, York, Pa., USA) is a resin marketed as a light-cured pit and fissure sealant [Muller-Bolla et al, 2006]. It displays good wettability of enamel fissure surfaces in vivo, leading us to expect that it might offer good miscibility with HAP in vitro.…”

Avaliação dos selantes de fossas e fissuras aplicados por estudantes de Odontologia

“…Esses autores verificaram que não há relação entre o tipo de operador e falhas na aplicação de selantes de fossas e fissuras, tendo sido comparados selantes aplicados por estudantes de Graduação e residentes de um programa de Odontopediatria. De forma similar, em alguns estudos que avaliaram o desempenho de selantes de fossas e fissuras aplicados por cirurgiões-dentistas e técnicos de higiene bucal, verificou-se que não houve diferença estatisticamente significante entre estas duas categorias profissionais 21,22,25,30 . Neste estudo, não havia a intenção de realizar comparações, mas sim avaliar os procedimentos que foram realizados por estudantes de Graduação em Odontologia que haviam tido contato recente com este tipo de procedimento.…”

“…Os índices de retenção de selantes de fossas e fissuras são variáveis, mas tendem a permanecer por longos períodos de tempo, independentemente do profissional que realiza a aplicação 4,12,[22][23][24][25] . Em vários estudos, verificou-se que selantes aplicados por assistentes de profissionais apresentaram índices de retenção tão significativos quanto aqueles aplicados pelos cirurgiões-dentistas 22,23,26,30 .…”
