Abstract
Background/objectives: The aim of this study was to examine if a person's preferred chewing side (PCS) corresponds to his/her hemispheric body laterality (HBL) or is dominated by the dental state.
Methods: After ethical approval, 82 volunteers were recruited. Asymmetry of bite force (ABF) was tested using an occlusal force-meter (GM-10) on both sides separately. The occlusal contact area (OCA) was observed using a pressure-indicating film (GC Fujifilm Prescale). The PCS was evaluated using an asymmetry index (ASI) or a visual analogue scale (VAS). Both tests were repeated. For the HBL, participants underwent four different tests to assess handedness, footedness, earedness and eyedness, respectively. Statistical analysis comprised kappa agreement for HBL tests and their repetition, as well as paired Wilcoxon tests for intraoral parameters.
Results: Hand, eye and ear showed a substantial reproducibility, while foot produced moderate agreement (kappa = 0.58, p < 0.001). No correlation was found between a participant's PCS and HBL, with the exception of EAR with VAS (kappa = 0.29, p = 0.001). There was a significant correlation between ABF and the number of residual teeth (NNT) both for PCS (p < 0.01; r2 = 0.29) and NPCS (p < 0.01; r2 = 0.18). There was no significant difference between PCS and NPCS for OCA (p = 0.13). The results revealed a significantly higher number of residual posterior teeth on the participant's PCS (for VAS p < 0.0001; ASI p < 0.03).
Conclusion: Masticatory laterality does not correspond to body hemispheric laterality. Rather than HBL, the number of residual teeth seems to determine on which side a person prefers to chew.
期刊介绍：
Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function.
Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology.
The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
