Relationship Between Self-assessed Quality Of Mastication, Occlusion Dynamics And Masticatory Function
Objectives: To determine to what extent is self-assessment of masticatory function related to the objective quality of mastication and clinical assessment of mandibular dynamics.
Methods: A total of 26 examinees were included in the pilot research, of which 15 women aged 17-34 years (median 24). Patients fulfilled self-assessment Chewing function questionnaire (CFQ), while clinical evaluation and function analysis included The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) protocol. Patients chewed on a bolus made of silicone (Optosil®)(r=5mm) during 20 seconds. Bolus was analyzed with photo scanner (Image 1.49p, Wayne Rasband, National Institute of Health, USA). For the purpose of assessment of mastication efficiency mean range of Feret diameter of masticated particles was used (distance of the tangent drawn to the opposite side of the particles) together with their total area.
Results: Increased self-assessed disruption of masticatory function (CFQ) was found more frequently in women (r=0.618) and correlated with poor oral health (r=0.510; p<0.05). In addition, the increased pain intensity, reduced unassisted and assisted mouth opening (r=-0.443-(-0.635)), and increased frequency of disrupted everyday activity (r=0.899; p<0.05) were more pronounced in patients with lower self-assessment of masticatory function. Greater surface and Feret diameter suggested poorer quality of mastication of silicone bolus, which was connected with an increased self-assessment disruption of masticatory function (r=0.460-0.541; p<0.05).
Conclusions: Self-assessed masticatory function may be positively correlated with objective situation. Patients with temporomandibular symptomatology have lower masticatory function efficiency.
