Unintentional removal of a developing permanent premolar during primary molar extraction: a 10-year case report.

A 14-year-old girl underwent extraction of an ankylosed primary left second molar as requested by her orthodontist. The developing mandibular left second premolar (tooth 20) was unintentionally removed during extraction of the primary molar. Immediate measures were taken to reimplant tooth 20.

One-year clinical performance of a self-etching adhesive in class V resin composites cured by two methods.

This study evaluated the clinical performance of a self-etching adhesive for resin composites over one year. Thirty pairs of restorations of Pertac II, using the adhesive Prompt L-Pop, were placed in caries-free cervical erosion/abfraction lesions without tooth preparation. One of each pair was cured using "soft-start" polymerization, while the other was polymerized with high-intensity halogen light.
