“…Unilateral chewing was reported by 22.2% of the total sample without significant difference among groups or association with TMJ pain/clicking. These results differ from the study of Yalçin et al, 30 that found a higher frequency (45.6%) of unilateral chewing with a significant association with TMD. Differences in methodologies may explain the divergence of the results: in the study of Yalçin et al, 30 presence, and not the frequency, of unilateral chewing was considered to establish the presence of the habit; in addition, no specific group of TMD was evaluated.…”

The present cross-sectional case-control study aimed to determine if there is an association between specific oral behaviors, sleep bruxism (SB), awake bruxism (AB), and painful temporomandibular joint (TMJ) clicking. Ninety individuals were dived into three groups; Group 1 (n = 30): painful TMJ clicking; Group 2 (n = 30): painless TMJ clicking; and Group 3 (n = 30): control group. The following clinical data were studied: oral behaviors (unilateral chewing, gum chewing, nail biting, foreign objects biting, leaning with jaw against the hand, and sleeping in a position that pressures the jaw), SB, AB (including the frequency in 10 days, evaluated by ecological momentary assessment), and malocclusions investigated based on clinical inspections (anterior open bite, posterior cross-bite, abnormal overbite/overjet, occlusal guidance, mediotrusive and/or laterotrusive interferences, retruded contact position to maximum intercuspation slide, missing posterior teeth). All statistical tests (Kolmogorov-Smirnov, chi-square, and one-way ANOVA) were performed with a 5% significance level. Group 1 had the highest frequency of and a significant association with leaning with jaw in the hand, sleeping position that pressures the jaw, gum chewing, nail biting, and AB (p<0.05). Gum chewing, nail biting, and AB were associated with Group 2 only when compared to Group 3 (p<0.05). No significant difference among groups was found for other behaviors (unilateral chewing and foreign objects biting), SB, and all malocclusions (p>0.05). It can be concluded that patients with painful TMJ clicking had a higher frequency of and a significant association with some specific harmful behaviors and AB.

“…A total of 90 patients who sought treatment of TMD in the department of stomatology at Chinese People’s Liberation Army General Hospital were randomly selected, and a written informed consent was obtained from each participant. The diagnose of TMD was made according to DC/TMD [ 19 ], the symptoms included unilateral joint pain, joint noise (clicking or crepitus) for more than 30 days. The exclusion criteria included masticatory muscle disorders, severe malocclusion, parafunction, traumatic injuries, congenital deformity, and a history of TMD treatment.…”

“…Chewing side preference (CSP) or unilateral chewing, observed in 45–98% of the population [ 15 ], have been viewed as one potential contributor of TMDs [ 16 – 18 ]. Firstly, people with CSP have a higher prevalence of TMDs and also a great majority of TMD patients show CSP [ 16 , 17 , 19 ]. Secondly, the preferred chewing side often is the symptomatic side of the joints in TMD patients [ 20 ].…”

Background Chewing side preference (CSP) has been proposed as one etiology of temporomandibular disorders (TMDs) as it can induce the structural changes of the temporomandibular joint. But its association with the inclination of the articular eminence (IAE) is unknown. This study aimed to compare IAE between patients with CSP and without CSP. Methods Cone-beam computed tomography images of 90 patients with TMD (mean age of 45.6 years, 69 with CSP, 21 without CSP) and 20 participants without TMD and CSP (mean age of 41.3 years) were measured to compare IAE and depth of the glenoid fossa (DGF) Results IAE and DGF showed a positive correlation among all the participants. Compared with the participants without TMD and CSP, the TMD patients without CSP presented a similar IAE but with a significantly higher value of DGF (p < 0.05); in contrast, the TMD patients with CSP presented a significantly greater IAE and DGF (p < 0.05). No bilateral differences in IAE and DGF were observed in all the participants. Except the male patients with CSP had a deeper fossa than did the female, no differences in IAE and DGF according to gender were observed. Conclusions TMD patients with CSP seem to have a deep glenoid fossa with steep eminence which might be considered one characteristic imaging feature.

“…Although mastication may be bilateral or may alternate involving both sides, it is thought that most people (from 45% to 98%) chew more on one particular side; that is, they have a preferred chewing side (PCS) . It has been reported that a unilateral masticatory pattern, or unilateral chewing, may be related to temporomandibular disorders, possible sleep bruxism, restricted mobility, lower oral health‐related quality of life and underweight . Bilateral mastication may have physiological advantages including enhancement of the rate of saliva production facilitating bolus formation, enhancement of flavour release and taste appreciation, and active food reduction on the contralateral side, resulting in higher efficiency …”

Objective This study assessed changes in masticatory laterality in patients with unilateral posterior missing teeth 3 months after treatment with an implant‐supported fixed partial prosthesis (ISFPP). Methods Thirty patients with unilateral posterior missing teeth participated in this prospective study. They were treated with one‐, two‐ or three‐unit ISFPPs. The control group comprised 10 healthy individuals with complete natural dentition. Each participant performed masticatory assays at baseline and at 3‐month follow‐up, chewing pieces of silicon inside a latex bag. Masticatory laterality was determined using three different methods: assessment of the first chewing cycle, of all cycles and application of a visual analogue scale. Data were compared using the Kruskal‐Wallis or the Mann‐Whitney U test as appropriate. Results Three months after treatment, a significant change in the asymmetry index towards the treated side and a significant reduction in the Unilateral Chewing Index were observed in the ISFPP group. No significant differences in masticatory laterality between groups were detected at 3‐month follow‐up, regardless of the method assessed. Conclusion Treatment with ISFPPs alters the masticatory laterality, moving it to the treated side and increasing the degree of bilateral chewing in patients with unilateral posterior missing teeth.
