To answer a clinical research question: 'is there any association between features of dental occlusion and temporomandibular disorders (TMD)?' A systematic literature review was performed. Inclusion was based on: (i) the type of study, viz., clinical studies on adults assessing the association between TMD (e.g., signs, symptoms, specific diagnoses) and features of dental occlusion by means of single or multiple variable analysis, and (ii) their internal validity, viz., use of clinical assessment approaches to TMD diagnosis. The search accounted for 25 papers included in the review, 10 of which with multiple variable analysis. Quality assessment showed some possible shortcomings, mainly related with the unspecified representativeness of study populations. Seventeen (N = 17) articles compared TMD patients with non-TMD individuals, whilst eight papers compared the features of dental occlusion in individuals with TMD signs/symptoms and healthy subjects in non-patient populations. Findings are quite consistent towards a lack of clinically relevant association between TMD and dental occlusion. Only two (i.e., centric relation [CR]-maximum intercuspation [MI] slide and mediotrusive interferences) of the almost forty occlusion features evaluated in the various studies were associated with TMD in the majority (e.g., at least 50%) of single variable analyses in patient populations. Only mediotrusive interferences are associated with TMD in the majority of multiple variable analyses. Such association does not imply a causal relationship and may even have opposite implications than commonly believed (i.e., interferences being the result, and not the cause, of TMD). Findings support the absence of a disease-specific association. Based on that, there seems to lack ground to further hypothesise a role for dental occlusion in the pathophysiology of TMD. Clinicians are encouraged to abandon the old gnathological paradigm in TMD practice.

“…Observation of the occurrence of symptoms such as: tooth wear (TW), linea alba, tongue indentations, and gingival recessions may indicate the performance of parafunctional activities like teeth clenching, bruxing, or buccal mucosa chewing (Ferreira et al., 2014; Feu et al., 2013; Owczarek et al., 2020). In the conducted study, TW was the most common symptom of parafunctions among physiotherapists.…”

“…Numerous researchers have described positive association between stressful life events and the performance of multiple oral parafunctions (Emodi-Perlman et al, 2012;Owczarek et al, 2020;Stocka, Kuc, Sierpinska, Golebiewska, & Wieczorek, 2015;Wieckiewicz et al, 2014). Across previous years, many studies contributed to the statement that oral parafunctional activity is associated with temporomandibular disorders (TMD) signs and symptoms-having an influence on its development (Ferreira, Simamoto-Júnior, Novais, Tavares, & Fernandes-Neto, 2014;Ohrbach et al, 2013;Panek et al, 2012;Więckiewicz, Paradowska-Stolarz, & Więckiewicz, 2014).…”

Aims:The purpose of this study was to assess the multifactorial etiology of temporomandibular disorders (TMD). To this end, prevalence of occlusal factors and parafunctional habits was investigated and correlated in two groups: patients with TMD (case group) and patients without TMD (control group).Methods: Prevalence of 7 static and 4 dynamic malocclusion features, and some parafunctional activities (nail biting, teeth grinding, teeth clenching, lips and cheeks biting, pens chewing, mandibular jaw moves habit…) were recorded in the two groups. Case group consisted of 30 patients with a diagnosis of myofascial pain, with or without limited opening, and/or disk displacement with or without reduction. Control group consisted of 30 patients without TMD. Univariate and multivariate analysis were used to identify the significant associations between occlusal variables, oral parafunctions and temporomandibular disorders.Results: All patients in case group, and 93.3% in control group had at least one malocclusion, and a statistically significant association between TMD and three malocclusions (two dynamic malocclusion features: mediotrusive interferences, laterotrusive interferences, and one static malocclusion: overbite >4 mm) was shown. Regarding parafunctional activities, all patients in case group, and 93,3% in control group had at least one parafunction, and the mean number of parafunctions per patient was significantly higher in case group than in control group. Besides, an association between TMD and some parafunctions was shown. Conclusion:Given the multifactorial nature of TMD, a behavioral reeducation to reduce parafunctional activities could be the first phase of the care for TMD patients and could prevent TMD development. Besides, special attention should be given to normocclusion criteria. These criteria must be fulfilled for any dental care.
