Photodynamic therapy of oral lichen planus.

Oral lichen planus (OLP) is a chronic inflammatory and immune-mediated disease affecting the oral mucosa.

Eating, drinking and oral hygiene procedures may be painful resulting in reduced quality of life (QOL).

Five-minute Apgar score ≤ 5 and Molar Incisor Hypomineralisation (MIH) - a case control study.

Background: The aetiology of molar incisor hypomineralisation (MIH) is unclear. The asymmetric distribution of MIH in the dentition may indicate that an insult of short duration that affects ameloblasts at a vulnerable stage could be a causative factor. Apgar ≤ 5 at 5 min may indicate asphyxia (hypoxic-ischemic insult) during birth.
