Investigation of Adolescents With Nocturnal Bruxism
The aim of this study is to examine the effects of bruxism on mandibular movement capacity, cervical proprioception, posture and quality of life in adolescents diagnosed with nocturnal bruxism (clenching and grinding teeth while sleeping) between the ages of 13-18 and to compare them with healthy adolescents.

Method: A total of 40 adolescents, 20 with nocturnal bruxism and 20 healthy, will be included in the study. Mandibular movement capacity will be evaluated with a caliper and ruler, cervical proprioception with a CROM device, posture with the New York Posture Scale, and quality of life with the PedsQL 13-18 age scale.

Hypotheses:

H1: Nocturnal bruxism reduces the movement capacity of the mandible in adolescents.

H2: Nocturnal bruxism reduces cervical proprioception in adolescents. H3: Posture disorder increases in adolescents with nocturnal bruxism. H4: Nocturnal bruxism affects the level of daily life quality in adolescents.
