A comparative microleakage evaluation of three different base materials in Class I cavity in deciduous molars in sandwich technique using dye penetration and dentin surface interface by scanning electron microscope.

Introduction: A major objective in restorative dentistry is the control of marginal leakage, which may occur because of dimensional changes or lack of adaptation of restorative material to the cavity preparation. Numerous techniques have been advocated to overcome polymerization shrinkage in composite restorations.

Aim And Objectives: This study investigated microleakage of three different bases under composite resin in sandwich technique using dye penetration and dentin surface interface using scanning electron microscope (SEM).

Compliance with supportive periodontal therapy among patients with aggressive and chronic periodontitis.

Compliance with supportive periodontal therapy (SPT) depends on many factors but is generally poor. We compared SPT compliance among patients with aggressive and chronic periodontitis. This single-center longitudinal observational study enrolled 101 patients with generalized aggressive periodontitis (GAP; n = 52) or generalized chronic periodontitis (GCP; n = 49) to compare SPT compliance.
