Abstract

Introduction: Endemic fluorosis resulting from high fluoride concentration in groundwater is a major public health problem. India is among the numerous nations, where fluoride sullied groundwater is creating wellbeing issues. Safe drinking water in rural areas of India is predominantly rely on groundwater sources, which are exceptionally contaminated with fluoride.

Aim: To investigate the association of temporomandibular joint Signs & Symptoms with Dental Fluorosis & Skeletal Manifestations among people living in Dad, Bokersal & Deotalab villages of Dungarpur District, Rajasthan, India.

Materials and methods: The study group consisted of 750 subjects who were born & brought up in Dad, Bokersal & Deotalab villages of Dungarpur District, Rajasthan. Temporomandibular joint & Dental fluorosis was assessed by performing type III clinical examination according to WHO guidelines (1997). For the assessment of skeletal manifestations, participants were asked to perform three diagnostic tests: (1)Touching the toes without bending the knees; (2) Touching the chest with the chin; (3) Stretching the arms sideways & folding the arms to touch the back of the head. Chi Square test & Multiple Logistic Regression were applied for statistical analysis.

Results: Among the 750 (462 males & 288 females) who participated in the study, 53% had moderate grade of dental fluorosis. The most prominent symptom suggesting Temporomandibular Joint Disorder was the clicking sound affecting 21.4% population.(p>0.001). TMJ Signs & Symptoms were prominent in the age group of 45-54 years & males were highly affected than females.

Conclusion: Clinical examination of TMJ in Dental Fluorosis & Skeletal Fluorosis subjects showed a significant association with Dental Fluorosis & Skeletal Fluorosis.

Keywords: Dean’s fluorosis index; Skeletal fluorosis; TMJ.
