Symptoms and signs of temporomandibular disorders among elderly Vietnamese

Abstract

Background: To assess the prevalence of the symptoms and signs of temporomandibular disorders (TMDs) and determine the prevalence of TMDs among elderly Vietnamese aged 65-74 years old. Methods: A cross-sectional study was conducted among 258 participants aged 65-74 years old (128 females and 130 males) using two strategies for TMD diagnosis: a clinical examination of the temporomandibular joint and its associated structures using the Diagnostic Criteria for Temporomandibular Disorders Axis I; and a set of 14 questions regarding TMD symptoms to obtain anamnestic data. Results: The prevalence of TMD symptoms was: headache 49.6%; temporomandibular joint noise 28.0%; orofacial pain 25.2%; jaw locking 3.1%; 62.5% of participants had at least one TMD symptom. Headaches were more prevalent in females than males (p=0.009) and rural than urban residents (p<0.001). The most frequent signs were temporomandibular joint crepitus (50.4%), clicking (48.1%) and mouth-opening deviation (37.6%). Temporomandibular joint crepitus and mouthopening deviation were more frequent among rural than urban (p=0.024 and p<0.001, respectively). TMD was found in 56.6% of the total sample. Of the TMD sufferers, 37.6% were diagnosed with disc displacement, 34.9% with degenerative joint disease, 3.5% with myalgia and 1.2% with arthralgia. Conclusions: More than half of elderly Vietnamese have at least one TMD symptom. TMD sounds were the most common clinical sign of TMD. There were no differences between the genders or place of residence and TMD diagnosis. Disc displacement and degenerative joint disease were most prevalent among elderly Vietnamese.

Association between temporomandibular disorder symptoms and demographic, dental and behavioral factors in the elderly: a populationbased cross-sectional study

“…TMD symptoms and had similar characteristics to other studies that used FAI, both in home-based studies 11,15 and in others developed in universities or coexistence centers 19,20,33 , in which there is a prevalence around 50%, regardless of severity. Likewise, cross-sectional studies using other tools and/or clinical exams also reported similar prevalences 20,22,[34][35][36] . In general, regardless of the study design and tools used, the prevalence of TMD was high among the elderly.…”

Effect of Prolonged Endodontic Treatment on Temporomandibular Joint and Masticatory Muscles

“…[36][37][38][39] However, in the present study, it was found that patients who were over 50 years of age were affected more than patients <50 years. Nguyen et al 21 also reported high prevalence of TMDs among an elderly Vietnamese population and TMD symptoms occurred among 62.5% of the sample. This result was much higher compared with elderly populations in Sweden (18%), 40 Brazil (35.8%), 41 and Nigeria (17.4%).…”

“…The assessment of TMD is also based on the clinical sign of the mouth opening pattern. Nguyen et al 21 in a study reported a mouth-opening deviation occurred in 37.6% of the elderly and 9.7% had a limited mouth opening. A similar study finding showed that 7.9% of elderly Japanese exhibited restricted mouth opening, 22 and another study has reported that the elderly have impaired maximal jawopening capacities compared with other age groups.…”

“…Muscles of mastication and articular ligaments during such procedures are stressed out for a longer period of time and this causes muscle contractions, pain, and discomfort with limited mouth opening. 18 A study conducted by Nguyen et al 21 found that muscle tenderness occurred more often in the temporalis, masseter, and lateral pterygoid muscles than in the posterior mandibular and submandibular regions. This finding was expected because the hyperactivity of the main masticatory muscles often causes tenderness and has been associated with TMD.…”

Comparison of Dental Status and Oral Function Between the Elderly With and Without Temporomandibular Disorders

“…The total sample comprised 258 volunteer participants aged 65-74 years in Danang City, Vietnam. Based on clinical examination of TMD according to DC/TMD axis I [15], our previous study revealed that 56.6% (n = 146) of the total sample were diagnosed with TMD (TMD group) and 43.4% (n = 112) were free of TMD (non-TMD group) [2]. In the current study, the participants of both groups were invited to examine dental status and evaluate oral function.…”
