[Effect of molar incisor hypomineralization on oral health-related quality of life in children and adolescents: a systematic review].

Introduction: Hypersensitivity, altered dental appearance and fractures are common problems in molar incisor hypomineralization that generate functional and socio-emotional problems.

Objective: to evaluate the effect of MIH on oral health-related quality of life in children and adolescents.

Materials And Methods: A systematic bibliographic search was carried out in electronic databases (Pubmed, Epistemonikos, Dentistry & Oral Sciences Source and Virtual Health Library).

Clinical comparison of pain perception rates between computerized local anesthesia and conventional syringe in pediatric patients.

The purpose of this study was to evaluate pain perception rates in pediatric patients by comparing computerized injection device and traditional injection procedure. In a clinical trial, by using a crossover design, sixty-four patients were randomly assigned to receive, in consecutive sessions, dental anesthetic techniques with either traditional or computerized device. Visual Analogue Scale qualification and heart rate monitoring as physiologic indicator of pain response were used for the evaluation.
