“…Many publications have concluded malocclusion is not an underlying cause of TMD, but actually may result from TMD [17][18][19] . Parafunctions such as bruxism and excessive gum chewing have also been linked to increasing the risk of TMD [20,21] . This correlation is likely due to the increased loading of the TMJ as evident by finite element analysis [22] .…”

Tissue engineering potentially offers new treatments for disorders of the temporomandibular joint which frequently afflict patients. Damage or disease in this area adversely affects masticatory function and speaking, reducing patients' quality of life. Effective treatment options for patients suffering from severe temporomandibular joint disorders are in high demand because surgical options are restricted to removal of damaged tissue or complete replacement of the joint with prosthetics. Tissue engineering approaches for the temporomandibular joint are a promising alternative to the limited clinical treatment options. However, tissue engineering is still a developing field and only in its formative years for the temporomandibular joint. This review outlines the anatomical and physiological characteristics of the temporomandibular joint, clinical management of temporomandibular joint disorder, and current perspectives in the tissue engineering approach for the temporomandibular joint disorder. The tissue engineering perspectives have been categorized according to the primary structures of the temporomandibular joint: the disc, the mandibular condyle, and the glenoid fossa. In each section, contemporary approaches in cellularization, growth factor selection, and scaffold fabrication strategies are reviewed in detail along with their achievements and challenges.

“…This correlation is likely due to the increased loading of the TMJ as evident by finite element analysis [22] . Trauma due to fracture or whiplash has also been evaluated as a contributing factor for TMD, and both of these injuries are correlated with an increased risk of TMD [21,23,24] .…”

“…These two OBs were also associated with painless TMJ clicking, but only when compared to the control group (Table 1). Gum chewing was one of the most prevalent OB (42.2% of the entire sample), and its association with painful TMJ clicking and with painless TMJ clicking was not surprising, since a higher incidence of TMJ clicking and arthralgia in individuals with the habit of chewing gum had already been reported, 22,23,24 being a potential contributing factor for these conditions. 22 Possibly, the high compressive forces within the joint due to the constant chewing contribute to squeeze the disc off the condyle and increase the sensitivity of retrodiscal tissues.…”

Oral behaviors, bruxism, malocclusion and painful temporomandibular joint clicking: is there an association?

et al. 2021

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.

“…Their overall results should read "The comparison between the two follow-up evaluations (12 and 24 months from baseline) showed no statistically significant differences between the two groups" but xylitol gum chewing showed slightly lower dental caries experience in the severe-caries group. However, gum chewing may be contraindicated in older adults to avoid temporomandibular dysfunction [Tabrizi et al, 2014;Nguyen et al, 2018].…”
