Comparative evaluation of retention and caries incidence of three different pit and fissure sealants using “CCC†evaluation system- A Double Blinded Randomized Controlled Clinical Trials

The dental council of India National Oral Health Survey from 2002-2003 revealed the prevalence of dental caries is 49.8% with a mean decayed, missing and filled teeth (DMFT) index of 2.5 among 12 years old individuals and 3.4 among the 15 years old individuals. With this picture in mind, the public health dentist has a moral obligation to spread awareness on oral diseases and to promote oral health ultimately leading to a better quality of life. In alignment with the principle of “prevention is better than cureâ€, in depth research on pit and fissure sealants can prove to be a valuable tool in reduction of mean DMFT rate in a community. In consequence, a double blinded randomized controlled clinical trial will be done using three different pit and fissure sealant among 12 to 15 year old young adolescents in rural Tamil Nadu with the follow up of 1 year where the evaluation will be done every 3 months interval. A total of 246 participants were randomly allocated to three groups (n=82).

VOCO twinky star flow (Compomer) , Ionoseal (Flowable GIC), and Ultraseal XT hydro (Hydrophilic sealant) are the three different types of sealants that will be used in the trial.. A single operator will perform the sealant application in the allocated tooth during the single visit.

The followup examination and evaluation of the pit and fissure sealant will be performed by the primary investigator who was blinded to interventional groups. At 3, 6, 9 and 12 month intervals, the sealants will be evaluated using the CCC evaluation system.
