Clinical Evaluation of Retention in Hydrophobic and Hydrophillic Pit and Fissure Sealants-A Two Year Follow-Up Study

Abstract

Objectives:The present in vivo study is done to compare and evaluate the retention of the traditional hydrophobic pit and fissure sealant with a hydrophilic resin-based sealant on first permanent molars and to compare the sealant retention in maxillary and mandibular first permanent molars. Materials and Methods: In this randomized clinical trial 212 permanent first molars from 76 subjects are considered in this study. Out of which 106 right side upper & lower first molars were sealed with Delton FS (Group I) and the remaining 106 left side upper & lower first molars were sealed with Embrace Wet Bond sealant (Group II). Clinical evaluation by both visual and tactile examination was carried out -immediately after sealant application, at 1,6,12,18 and 24 months using Simonsen's criteria. Results: At the end of two years 67.9% of permanent molars of group II showed completely retained sealants compared to 45.3% of permanent molars of group I. Conspicuously 56.6% upper teeth in group II retained sealant, whereas only 17% of upper teeth retained sealant in group I and is statistically significant (p=0.01). Conclusion: It can be concluded that hydrophilic sealant may be used as effective pit and fissure sealants especially in children with high risk of caries, excessive salivation, mentally and physically challenged, very young children, uncooperative child and partially erupted molars and community care programs.

“…Foods and dental plaque easily accumulate in these areas and cannot be removed effectively by the patient. Moreover, lack of saliva flow to the fissures and insufficient intake of remineralization agents do not compensate for a high incidence of occlusal caries 2) . Fissure sealants isolate pits and fissures from the bacteria and their by-products, provide a mechanical barrier, and avoid accumulation of dental plaque.…”

“…Yapılan çalışmalarda ise alt çenedeki dişlerde daha yüksek retansiyon oranı görüldüğü bildirilmiş; araştırmacılar bu sonucu, direkt görüş sonucu uygulamanın kolay olması ve üst çenedeki dişlerin alt çenedeki dişlere göre oklüzal streslere daha erken maruz kalması ile açıklamışlar-dır. 27,30 Bununla birlikte, alt çenedeki dişlerin üst çenedeki diş-lere göre daha uzun sürme periyoduna sahip olduğunu ve bunun da retansiyonu olumsuz etkilediğini bildiren araştırmacılar da bulunmaktadır. 6 Çalışmamızda, uygulanan fissür örtücülerin 15 ay sonunda sadece %24,2'sinde retansiyon kaybı gözlenmemiştir.…”

Ancak çalışmamızda, sürmekte olan dişlerde hidrofilik rezin içerikli fissür örtücü-ler, hidrofobik rezin içerikli fissür örtücülerden daha başarısız bulunmuştur.…”

“…A study was conducted to compare and evaluate hydrophobic and hydrophilic pit and fissure sealants where the two groups of children used hydrophobic and hydrophilic fissure sealants and it was concluded that the second group of sealants provided better results and was highly recommended to be used in children who were very young, high risk of caries, excessive salivation, mentally challenged and disabled, uncooperative and community care programs [2].…”
