Assessment of the impact of temporomandibular disorders on maximum bite force.

Aim: Temporomandibular disorders (TMD) refer to functional disorders of the masticatory system, temporomandibular joint (TMJ) and masticatory muscles. The main objective of this study was to determine whether and to what extent temporomandibular disorders (TMD) affect the maximum bite force (MBF).

Methods: The present study included subjects with and without temporomandibular disorder.

Analysis of the mineral composition of hypomineralized first permanent molars.

Background/aim: Hypomineralization of molars and incisors (molarincisor hypomineralization--MIH) is defined as enamel hypomineralization of systemic origin of one or more of the four first permanent molars, which may be associated with changes in the maxillary, and less frequently in the permanent mandibular in cisors. The aim of this study was to investigate the mineral content in hypomineralized teeth as a contribution to understanding the origin of these changes, which will be important for effective restorative approach.

Methods: A total of 10 extracted first permanent molars diagnosed with MIH were used in the study as the experimental group, and intact first premolars extracted for orthodontic reasons were used as the control group.
