ABSTRACT:

Tempero Mandibular Disorders (TMD) has multifactorial aetiologies with various initiating factors (trauma, parafunctional habits), predisposing factors (systematic, genetic, structural, psychological) and perpetuating factors (metabolic factors, muscle stress). Occurrence of sign and symptoms of TMD disorders in all age groups with low prevalence among adolescents. The range of symptoms occurring in adolescents are considered to be mild in nature. Non nutritional oral habits like lip biting, nail biting being associated with TMD among adolescents. Hence it is necessary to make the adolescents aware about the harmful oral habits that could lead to TMD.

AIM: To find whether harmful oral habits are associated with sign and symptoms of TMD among adolescents

MATERIALS AND METHODS: A cross sectional study is carried out among 100 adolescents as well as questionnaire filled to find out whether harmful oral habits are associated with signs and symptoms of TMD among adolescents.

RESULTS: The results revealed that 60 out of 80 participants had atleast mild subclinical symptom of TMD. 75% of patients had atleast one harmful/parafunctional habit. The great majority among them were lip biting, nail biting.

 

KEYWORDS: Temperomandibular disorder, adolescents, harmful habits.

 

 

 

 

INTRODUCTION:

Temporo mandibular disorder (TMD) is a heterogenous group of psychophysiological disorders commonly characterised by orofacial pain, chewing dysfunction or both. Various Epidemiological studies had shown occurrence of TMD in all age groups including children.TMD has multifactorial aetiologies with various initiating factors like trauma, parafunctional habits and predisposing factors like systematic, genetic, structural, psychological and perpetuating factors like metabolic factors, muscle stress [1,2].

 

It initially manifests as quintessential triology of sign and symptoms in which patient usually experience joint pain, clicking sound and difficulty in mouth opening [1]. Other commonly occurring sign and symptoms are soreness of muscles of mastication, attrition of teeth ,mobility of teeth, headaches in the temple, pain in forehead and eyes, pain in the back of the head , fullness in the ears, tinnitus, pressure on the eyes, sensitivity to light, lack of concentration [3].

 

MATERIALS AND METHODS:

A descriptive cross-sectional study was conducted in saveetha dental hospital, 100 adolescents were randomly selected. Sign and symptoms of TMD and parafunctional habits were analysed by using the questionnaire, which consisted of ten questions with yes/no response along with patient history and detailed clinical examination. According to guidelines of AAOP, three or more ‘Yes’ responses indicate TMD [1].

RESULTS:

Study population comprised of 58 male and 42 females age between 10-18. Twenty adolescents reported no sign or symptoms of TMD. Thirty four adolescents responded yes to atleast one statement of AAOP questionnaire and a total of 80 adolescents responded yes to three or more questions. Total number of twenty five participants had no harmful oral habits while 40% and 35% participants had presence of two, three or more habits respectively. Statistically significant association was found between nail biting, biting lip / objects, grinding of teeth with sign and symptoms of TMD (p ≤ 0.05).Top three symptoms of TMD reported by study population were headache, neck pain, toothache (48%), pain in mouth opening (35%) and jaw sounds (37%). [Table-1] describes the detailed description of sign and symptoms of TMD reported by the study population. There is a statistically significant association was found between patients with TMD and sign and symptoms like headache, pain in mouth opening, sounds from joint etc

DISCUSSION:

This study was aimed to find association between parafunctional habits and sign and symptoms of TMD among adolescent residing in Chennai. In present study there was statistically significant association between harmful oral habits like nail biting object/lip biting; grinding of teeth and sign and symptoms of TMD which was accordance to study done by Lauriti et al.,[5]. Lobbezoo et al., and Respetro C et al. was conducted a study on “bruxism, clenching/grinding of teeth, nail biting, object biting, forward thrust of mandible as parafunctions” [4,6]. In present study statistically significant association was found between Nail biting and TMD]. These parafunctional habits should be considered as risk factor for TMD as they act as triggering point for appearance of TMD due to its effect on stomatognathic system. Headache, neck pain, toothache (48%), sounds in the joint (37%) and pain in mouth opening (35%) were top three sign and symptoms of TMD, similarly Motta et al., was conducted among Brazilian adolescents [1]. Three sign and symptoms are considered as classic triad of TMD disorder occurring in a sequential pattern. Questionnaire can be used for screening and diagnosis of individuals with TMD disorders. These questionnaires can help in identification of individuals having sign and symptoms of TMD.

 

CONCLUSION:

This study says that there was an association between parafunctional habits and sign and symptoms of TMD. Non nutritional oral habits like lip biting, nail biting being associated with TMD among adolescents. Hence it is necessary to make the adolescents aware about the harmful oral habits that could lead to TMD.
