OBJECTIVES To examine the effects of dental fluorosis and total and self-etch bonding systems on microleakage of Class-V composite restorations in permanent molar teeth. METHODS Teeth were classified as three main groups according to Thylstrup-Fejerskov Index (TFI) as TFI=0, TFI=1-3 and TFI=4. Total and self-etching/bonding procedures were determined for each main group. Total-etching procedu...

In our previous studies, we developed the normal periodontal ligament index (nPLI) and residual periodontal ligament index (rPLI) to estimate residual periodontal ligament support for individual teeth during treatment planning for partially edentulous patients. To illustrate the applicability of the nPLI and rPLI, an occlusal-supporting ability (OSA) score calculated using these indices for the...
