Comparison of Different Methods of Enamel Preparation Before Pit and Fissure Sealants

Not Applicable

Completed

• Conditions: Enamel Lesions; Dental Caries
• Interventions: Procedure: air abrasion; Procedure: dental bur; Procedure: sono abrasion

• Registration Number: NCT02594020
• Lead Sponsor: Centre Hospitalier Universitaire de Nice

Brief Summary

This study concerns the prevention of dental caries by sealing pits and fissures of permanent molars with a photopolymerizable resin. It must compare these three techniques Microdentisty (air abrasion, abrasion and sound using small cutters) usually used to prepare micro cavities in the enamel and / or the outer third of the dentin. These three commonly used techniques have never been compared by retaining as endpoint retention of sealant. These techniques are painless and do not require local anesthesia.

Primary Outcome Measures

Name	Time	Method
observation of quality of treatment	2 years	Compare enamel preparation techniques of air abrasion and sound abrasion technique enameloplasty (pits and fissures extended to the dental bur) the more conventionally used to identify the most effective as using endpoint retention of material sealing of pits and fissures.
