Abstract

Introduction: Conditions of the temporomandibular joint (TMJ) are affected by changes in movement and load during the joint’s function, which can cause morphological changes in hard tissues, such as the condyle. Panoramic radiographs can provide an indication of changes in hard tissues in TMJ. Objectives: The aim of this study was to determine whether there was any correlation between mandibular condyle shapes as seen on panoramic radiographs and TMJ conditions in adult female participants. Methods: The participants of this study were 75 adult female patients who underwent a panoramic radiograph examination conducted at the Maranatha Dental Hospital Radiology Unit. The patients were clinically examined based on the Research Diagnostic Criteria for Clinical Temporomandibular Disorder (RDC/TMD) questionnaire and also their panoramic radiographs. The data from the patients were categorized into four groups according to the RDC/TMD: normal, muscle disorders, disc displacement, and other joint diseases. Next, the radiographs were analyzed by two observers to determine the condyle shapes. Condyle shapes were classified into four groups: ovoid, flat, erosion, and osteophyte. Result: This study showed that of 75 patients, the right TMJ was normal in 34 patients, 2 patients had muscle disorders, 24 demonstrated disc displacement, and 15 had other joint diseases. For the left side of the TMJ, 22 radiographs were normal, 2 revealed muscle disorders, 35 identified disc displacement, and 16 showed other joint diseases. There was a strong agreement between the two observers in determining the right (κ=0.681) and left condyle shapes (κ=0.652). All participants’ findings indicated that condyle shapes and TMJ conditions are highly correlated for both the right (η2=0.889) and left condyle (η2=0.762). Conclusion: This study concluded that mandibular condyle shapes seen on panoramic radiographs and TMJ conditions in adult female participants were highly correlated.

Abstract

Introduction: Tooth loss is one of the essential factors of oral health status, which affects individual quality of life and social factors. It is also a common oral health problem in adults and elders. A prolonged period of tooth loss, followed by an immediate replacement with dentures, can cause changes in occlusion due to the teeth' unsustainability; tooth position shift followed by extrusion leads to occlusion pattern disruption, resulting in gingival movement difficulties. This research analyses the correlation between posterior tooth loss and temporomandibular joint disorders in elders. Methods: Analytic observational with cross-sectional study. The sampling technique was simple random sampling, identifying a population of 39 people aged 60 to 75, consisting of 12 males and 27 females. The sample size was determined by the overall population size, calculated through the minimum single sample size formula incorporating the correlation coefficient (r). The primary data was obtained by completing the questionnaires and the respondents' clinical examination with the Helkimo index. Results: The findings showed that most respondents were female, 27 compared to 12. In terms of dysfunctional index data for tooth loss, the "Mild symptoms" were found to be predominant over "No symptoms", with the (HG) ≤ 4; while the (HG) ≥ 4, showed that the "No symptoms" were less common. Similarly, in the anamnesis index data, the "Mild symptoms" were the most common, with the (HG) ≤ 4; while the (HG) ≥ 4 showed that the "No symptoms" was predominated, with fewer cases of the "Mild symptoms" and the "Severe symptoms". The Spearman Correlation Rank test analysis showed that the r (coefficient of correlation) = 0,944, with p = 0.000. Conclusion: There is a relationship between posterior tooth loss and temporomandibular joint disorders in elders.
