Temporomandibular disorders and parafunctional oral habits: an anamnestic study

Abstract

Objective: To assess the frequency and severity of the signs and symptoms of temporomandibular disorders (TMD), the frequency of parafunctional oral habits and the correlation between the variables by means of the patients' perception regarding their problem. Methods:One hundred patients diagnosed with TMD, through a clinical examination of their masticatory system, answered the questions of a previously published protocol concerning the signs and symptoms most frequently reported in the literature.Results: According to the results from the non parametric statistical analysis, the frequency for the following signs and symptoms was significant: Fatigue and muscle pain, joint sounds, tinnitus, ear fullness, headache, chewing impairment and difficulty to yawn (p<0.01) and otalgia (p<0.05). As to the parafunctional oral habits, there was a significant presence of teeth clenching during the day and night (p<0.01) and teeth grinding at night (p<0.05). The variable correlation analysis showed that there was a positive correlation between symptom frequency and severity; age was correlated with the presence of otalgia, cervical pain and teeth sensitivity, besides being correlated with muscle and joint pain severity. Habit frequency was negatively correlated with age. TMD duration was also positively correlated with the symptoms of tinnitus, ear fullness, muscle and joint pain. Conclusion:The study results showed that the anamnestic assessment using ProDTMMulti can predict the severity of the TMD case.

Prevalence of malocclusion, oral parafunctions and temporomandibular disorder‐pain in Italian schoolchildren: An epidemiological study

“…Moreover, some studies have reported that the amount, frequency, intensity and duration of habits can determine the severity of signs and symptoms of TMD. 10 The prevalence of oral parafunctions in children ranges from 7% to 15.1%, 11 with girls reporting higher frequencies. 12 Frequently encountered oral parafunctions in children are bruxism, nail biting and non-nutritive sucking, 13 and the persistence of these activities might have detrimental effects on the oro-facial structures.…”

“…It is believed that oral habits can be considered as an important aetiologic factor of temporomandibular disorders (TMD), as they lead to a traumatic dental occlusion that may affect the teeth and the masticatory muscles and temporomandibular joints, causing the disruption of the functional balance of the stomatognathic system, or worsening the already present TMD. Moreover, some studies have reported that the amount, frequency, intensity and duration of habits can determine the severity of signs and symptoms of TMD . The prevalence of oral parafunctions in children ranges from 7% to 15.1%, with girls reporting higher frequencies .…”

“…Segundo a literatura, a DTM é uma patologia comum, cujos sinais e sintomas clínicos e subclínicos chegam a afetar em torno de 50% da população geral, sendo mais prevalente em mulheres, entre as idades de 20 e 40 anos (Cordeiro & Guimarães, 2012;Dugashvili et al, 2013;Oliveira et al, 2012). Os estudos demonstram que a DTM está relacionada a fatores psicológicos, emocionais, fi siopatológicos e comportamentais (Melchior et al, 2012;Sydney & Conti, 2011). No entanto, não existe consenso entre os pesquisadores acerca da etiologia exata da DTM.…”

“…A intensidade da dor referida pelos indivíduos com DTM e mensurada com base em uma escala de autorrelato constatou média total de 5,75 pontos, de acordo com a Tabela 2. Dessa forma, verifi ca-se que a intensidade da dor apresentou-se em nível moderado, o que pode estar relacionado à procura por atendimento odontológico (Conti et al, 2012;Melchior et al, 2012;Oliveira et al, 2012;Rollman et al, 2013). O período de tempo em que os 20 pacientes com DTM manifestaram dor variou de 12 a 240 meses; no entanto, a média permaneceu em 87 meses.…”

“…O período de tempo em que os 20 pacientes com DTM manifestaram dor variou de 12 a 240 meses; no entanto, a média permaneceu em 87 meses. A análise do grupo com DTM apontou que não há correlação entre o tempo e a intensidade da dor relatada (p=0,080), confi rmando os achados da literatura (Melchior et al, 2012).…”
