Amelogenesis imperfecta: therapeutic strategy from primary to permanent dentition across case reports.

Background: Hereditary enamel defect diseases are regrouped under the name "Amelogenesis Imperfecta" (AIH). Both dentitions are affected. Clinical expression is heterogeneous and varies between patients.

Phase III, randomized, double-blind, placebo-controlled trial of topical 2 % lidocaine for the prevention and treatment of oral mucosal pain in children.

Objectives: The aim of this study was to assess the efficacy in pain reduction of topical 2 % lidocaine compared to a placebo cream in children with oral mucosal lesions due to trauma or aphthous ulcers or in the prevention of clamp placement pain.

Materials And Methods: The design was a double-blind, randomized, placebo-controlled, four-center trial on 64 patients. Pain intensity and relief were measured using a 100-mm visual analog scale (VAS).
