Distribution patterns of enamel fluorosis in permanent dentition.

Purpose: To describe the different patterns of the intraoral distribution of enamel fluorosis in permanent dentition.

Materials And Methods: This cross-sectional analysis was conducted in Nalgonda district of Andhra Pradesh, India. A group of 1000 school children aged 13-15 years were selected by stratified cluster sampling from four different areas with different levels of naturally occurring fluoride in the drinking water.

Fracture resistance of microhybrid composite, nano composite and fibre-reinforced composite used for incisal edge restoration.

Traumatized anterior teeth need quick, aesthetic and functional repair. Along with aesthetics, the physical properties of restorative material should also be considered for long-lasting restoration. Fibre reinforcement has been tried as a newer technique to improve the physical properties of composite materials.
