Utjecaj učestalosti oralnih parafunkcija na terapijski učinak u pacijenata s temporomandibularnim poremećajima

Introduction: Since oral parafunctions are considered one of the possible risk factors for temporomandibular disorders (TMD) the purpose of this study was to determine whether the frequency of oral parafunctions would affect treatment response. Materials and Methods: Forty‐five participants, randomly assigned into treatment groups [physical therapy+education (PTE), stabilisation splint (SS) and thin thermoplastic foil as control therapy (CT)], were divided into “high‐frequency parafunction” (HFP) and low‐ frequency parafunction” (LFP) group according to the Oral Behavior Checklist score. The participants’ primary (pain intensity and range of opening) and secondary outcomes (anxiety symptoms, quality of life, perceived stress and global functional limitation) were followed for six months. The difference and interaction between groups was tested using ANCOVA and differences within groups were tested using ANOVA. Results: Participants with HFP presented significantly greater levels of anxiety (3rd month: p = .009 ; 6th month: p = .041) than participants with LFP. Within‐group analyses showed significant improvement of anxiety, but also the decrease of perceived stress and improvement of global limitation for the HFP group (p anx .= .015 ; p stress = .005 ; p limit = .001), but not for the LFP group. No interactions between type of treatment and a frequency of oral behaviors on treatment outcomes were found. Conclusion: When evaluating the effect of therapy, it is important to consider the presence of parafunctional behaviour. The therapeutic efficacy in participants with high-frequency parafunction, reflected as a significant reduction of anxiety, stress and functional limitation was present regardless of applied treatment. These results might indicate that the psychological factors, which are commonly associated with both TMD and oral parafunctions, respond well to used therapy.
