Effectiveness of Seven Types of Sealants: Retention after One Year

Abstract

AimThe aim of this study is to determine the retention rate and pattern of different pit and fissure sealants placed on the occlusal surface of newly erupted first permanent molars after 3, 6, 9, and 12 months.Materials and methodsSeventy children were enrolled in this study. They divided into seven groups (m = 10) according to the type of the sealant. The four permanent first molars of each child were sealed. The sealant was applied according to the instructions from the manufacturer. A clinical evaluation was carried out at 3, 6, 9, and 12 months. The clinical observations were divided into three categories: total retention (TR), partial retention (PR), and total loss (TL).ResultsThe resin-based sealant performed better than the glass ionomer-based sealant except for the Ketac Molar Easymix. At 3 months, there was no significant difference among all the tested groups (p > 0.05), while at 6, 9, and 12 months, there was a highly significant difference (p < 0.001). The glass carbomer sealant showed the least retention rate at all intervals.ConclusionWith an exception of the Ketac Molar Easymix, resin-based sealers performed better than glass ionomer-based sealers.Clinical significanceA proper application of pit and fissure sealant will decrease the chance for caries development in newly erupted teeth.How to cite this articleHassan AM, Mohammed SG.

Comparison of the Success Rate of Filled and Unfilled Resin- Based Fissure Sealants: A Systematic Review and Meta-analysis

“…We obtained the full texts and appraised them in detail. Five studies [ 11 - 15 ] had more than one group comparing filled and unfilled sealants that were included in the meta-analysis. Figure 2 provides detailed information about the included studies.…”

“…In the included studies, the detection bias was low in seven studies because the assessors were blind when evaluating the outcomes [ 7 , 15 , 16 , 18 , 21 , 24 , 26 ] . We could not specify detection bias for 12 studies and assumed the detection bias for these studies to be unclear [ 11 , 12 , 27 , 28 , 13 , 14 , 17 , 19 , 20 , 22 , 23 , 25 ] .…”

“…In evaluation of the attrition bias, the investigators in one study did not explain the reasons for missing outcome data, thus, the risk of this bias was high [ 24 ] . Four studies had an unclear ROB since the number of samples was not disclosed [ 11 , 17 , 18 , 25 ] . All other studies had a low ROB because they had no missing data, or the investigators explained the reasons for the dropouts [ 7 , 12 , 23 , 26 - 28 , 13 - 16 , 19 - 22 ].…”

Are glass carbomer sealants more efficient in preventing carious lesions in children’s permanent molars when compared to other sealant materials? A systematic review and meta-analysis.

“…Forty papers were excluded after the reading of abstracts, resulting in 14 fulltext papers for assessment of eligibility. From these, six papers were excluded due to different reasons: in vitro studies, 24,25 non-randomized trial, 26 cost-effectivity study 27,28 prevention of carious lesions in permanent molars with micro-cavities in dentin. 29 One project of clinical trials, registered at the Dutch Trial Registration Centre (# 1441), resulted in 6 different papers [19][20][21][22]30,31 that showed data from distinct follow-up periods and outcomes.…”

Comparative effectiveness research of two glass ionomer cements for primary molar fissure sealing

“…Многие авторы сообщают о позитивных результатах применения различных СИЦ для герметизации фиссур, преимущественно, в постоянных молярах [8][9][10], о преимуществе СИЦ над другими методами профилактики фиссурного кариеса [11,12]. В то же время СИЦ уступают другим материалам для герметизации фиссур зубов по показателям ретенции [13][14][15]. Однако простота технологии применения, привлекательная стоимость и не уступающая традиционным силантам противокариозная эффективность позволяет СИЦ успешно конкурировать с другими материалами [16,17].…”
