Moreover, measurement of the mean zones of inhibition was done.

An In-Vitro evaluation of resin infiltration system and conventional pit and fissure sealant on enamel properties in white spot lesions.

Background: Clinically appearing early caries are referred to as white spot lesions (WSLs). These lesions compromise esthetics and precede cavitation; therefore, they must be halted by effective materials.

Aim: To evaluate and compare the depth of penetration and effect of resin infiltration system (Icon) and other conventional pit and fissure sealants (Clinpro and Embrace) on enamel surface properties of WSLs.

A comparative evaluation of dental caries status and salivary properties of children aged 5-14 years undergoing treatment for acute lymphoblastic leukemia, type I diabetes mellitus, and asthma - .

Background: The subjective sensation of dry mouth, xerostomia, is a well-recognized problem in adults, however, relatively little attention has been paid to this issue in children. Xerostomia commonly occurs as an adverse effect of drugs in asthma and leukemia, which alter the composition and flow of saliva and systemic diseases, including diabetes. It decreases the oral pH and significantly increases the development of plaque and dental caries.

Effect of Casein Phosphopeptide-amorphous Calcium Phosphate and Calcium Sodium Phosphosilicate on Artificial Carious Lesions: An Study.

Aim: To compare new remineralizing agents calcium sodium phosphosilicate paste and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste with that of fluoridated toothpaste in remineralization of early carious lesions using scanning electron microscopy and energy-dispersive X-ray (SEM-EDX) analysis.
