Temporomandibular disorder (TMD) is a universal term referred to herein to collectively denote a series of functional disorders of orofacial structures, the temporomandibular joint (TMJ) and the masticatory muscles in particular.

The aim of our study was to determine the prevalence of temporomandibular disorders within the observed sample population of the northern part of Kosovo and Metohija, as well as the frequency of signs and symptoms of this type of disorder.

The study involved a sample of 300 subjects, aged 18-30 years. The sample comprised the target student population attending the University of Pristina, Kosovska Mitrovica. A random sample, intended for sampling without replacement, was drawn from the target population. All subjects underwent the Helkimo clinical dysfunction index analysis. Results of the analysis were quantified and expressed numerically, based on severity, as the Helkimo anamnestic dysfunction index (Ai) and the clinical dysfunction index (Di) with specific values assigned thereto accordingly.

The prevalence of temporomandibular disorders within the observed sample population totaled 50.7% (Di> 0). In the majority of patients a mild form of TMP (67%) was reported. Temporomandibular disorders were more common in women than in men, who appear to be three times as likely to develop the respective condition, demonstrating the ratio of 3:1. The most common TMD signs and symptoms implied mandibular kinetics disturbances (46%) and TMJ sounds (45%). The prevalence of pain during mandibular movements amounted to 9%, the palpable TMJ sensitivity to 20% and the palpable sensitivity of masticatory muscles 18%. Headache and otalgia were represented with 13%, that is, 3% in the observed sample.

Temporomandibular disorder analysis demonstrates high incidence in the population of the northern part of Kosovo and Metohija. These findings indicate the need for an extensive prevention, control and treatment of this type of disorder.
