Brief summary
Traditional approaches for preventing proximal lesions such as flossing and rinsing with fluoride usually have limited success as they rely heavily on patients’ compliance (Alm et al. 2007). More recently, treatment of proximal caries has been focussed on arresting initial caries by sealing these lesions with low viscosity resins (Ekstrand et al. 2010). Although early success has been reported using this technique, there is a need to gain access to the proximal lesions which requires physical separation of the teeth. As this technique usually involves two appointments, it is not practical for young children. A more conservative alternative would be to seal the teeth while it is possible to gain access to the proximal smooth surfaces before the contacts with adjacent teeth are established. There are a few stages in the development of the primary and permanent dentitions which provide windows of opportunity to gain such access to specific proximal surfaces of the posterior teeth. HYPOTHESIS We hypothesize that smooth surface sealants (SSS) placed prior to establishment of the proximal contacts can prevent proximal caries in teeth. AIMS Therefore the aims of the study are to: (1) Determine the caries incidence in sealed surfaces of primary and secondary teeth compared to unsealed surfaces in the same teeth in other quadrants of the mouth. (2) Evaluate the cost effectiveness of smooth surface sealants in preventing caries
Interventions
Application of smooth surface sealant on proximal and occlusal surface of first permanent and primary molars
The sealant to be used is a commercially available and TGA approved product named "G-Coat Plus" manufactured by GC, Tokyo, Japan
The sealant will be applied once at the start of the trial according to standard protocol for clinical application of sealant (eg: clean surface, apply G Coat Plus then set it with a light source)
