Summary Mandibular jaw opening was related with general joint mobility in a non‐patient adolescent group. The angular rotation of the mandible at maximum jaw opening was slightly larger in females than in males and significantly larger in hypermobile individuals. No significant relationship between linear measuring of maximal mandibular opening capacity and peripheral joint mobility was found either at active (AROM) or at passive range of mandibular opening (PROM). PROM was strongly correlated to the mandibular length. Clinical signs in the great jaw closer muscles could not be associated to decreased AROM. The mean value of the difference between PROM‐AROM (DPA) was 1.2mm. Frequent clenching and/or grinding was correlated to increased DPA only in hypermobile adolescents ( r =0.49***). Those with DPA exceeding 5 mm had all reciprocal clicking.
