Preventive and Therapeutic Proximal Sealants

It is of clinical importance to arrest the development of approximal caries at an early stage. The potential for initial caries to develop into manifest lesions has motivated studies on the use of sealants to arrest the progression of caries on both occlusal and approximal tooth surfaces. Therefore, the aim of the present study was to follow-up and examine after 3.5 years, the efficacy of sealing caries-free or non-cavitated mesial surfaces of first permanent molars abutting lesions on the distal surfaces of second primary molars. The null hypothesis tested here was that preventive and therapeutic sealants do not prevent the development or slow the progression of dental caries over a period of 3.5 years in comparison to non-sealed control surfaces.
