OBJECTIVE: To investigate mastication and swallowing disorders in patients with severe TMD referred to surgery. MATERIALS AND METHODS: Clinical and experimental study involving ten individuals with TMD submitted to deglutition videofluoroscopy. These patients did not have posterior teeth, mastication pain and food replacement in favor of pasty consistence food. The assessment of the oral and pharyngeal phases approached the following aspects: side of onset and preferential side for chewing, premature escape, remains of food residues in the oral cavity or in the pharyngeal recesses, number of necessary swallowing efforts, laryngeal penetration and/or tracheal aspiration. RESULTS: During mastication and the oral phase we observed tongue compensatory movements upon chewing (n = 7; 70%), premature escape (n = 4; 40%), food remains in the cavity after swallowing (n = 5; 50%) and an excessive number of deglutition efforts (n = 5; 50%). On the pharyngeal phase we observed food remains in the valleculae (n = 6; 60%), in the pyriform sinuses (n = 4; 40%); laryngeal penetration (n = 1; 10%) and tracheal aspiration (n = 4; 40%). CONCLUSION: TMD patients may have alterations in their chewing and swallowing patterns, with laryngeal penetration and/or tracheal aspiration. The study indicates the need for a multidisciplinary assessment because of dysphagia in TMD patients.
- ItemSomente MetadadadosCorrelação entre o limiar de dor à pressão e a intensidade de dor em individuos com disfunção temporomandibular submetidos a tratamento conservador(Universidade Federal de São Paulo (UNIFESP), 2014-12-18) Lalue, Monique [UNIFESP]; Alonso, Luis Garcia Alonso [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Pain is a sensation or unpleasant emotional experience associated with actual or potential tissue damage, which features the most prevalent clinical symptoms in individuals with temporomandibular disorders (TMD). However, its quantification is still precarious regarding existing methods, because although they are well established are not very reliable to assess the clinical course of patients. Objective: To measure at different times, with a digital pressure algometer accuracy, the threshold of pain on pressure in masseter and temporalis muscles of TMD patients, who underwent conservative treatment. Methodology: To date were evaluated 27 individuals who had possessed DTM and tenderness in the masseter and temporalis muscles. After diagnostic measurements were performed pain threshold to pressure of these muscles on both sides of the head and the lateral pole of the temporomandibular joint, by placing the pressure algometer in the region being evaluated. For each individual, was established as a conservative treatment that included therapeutic and thermal therapy exercises. These individuals were reevaluated after 15 days and new measurements were obtained. Also will be evaluated after 45 and 75 days of starting treatment. Results: A total of 21 (77.8%) patients adhere to treatment. The Wilcoxon test to evaluate the improvement of the pain threshold to pressure in the first 15 days of treatment in each measured region, both on the right as on the left side of these patients showed statistically significant differences in the measurements. Right masseter Z = 2.24 (p = 0.0250), right temporal Z = 2.13 (p = 0.0325), for the right side Z = 2.55 (p = 0.0106), left masseter Z = 2.74 (p = 0.0060), left temporal Z = 2.27 (p = 0.0228) and left lateral pole Z = 3.43 (p = 0.0006). Conclusion: Based on these results we can infer that the imposition of a conservative treatment in patients with TMD shows positive results in increasing the pressure pain threshold.
- ItemSomente MetadadadosPolimorfismos dos genes nr3c1, chrm2, tph1 e mc1r e sua correlação com marcadores de ancestralidade e fatores biopsicossociais em indivíduos com disfunção temporomandibular(Universidade Federal de São Paulo (UNIFESP), 2015-05-28) Ferreira, Mariana Brandao [UNIFESP]; Alonso, Luis Garcia Alonso [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Objectives: To assess a sample of 105 patients with temporomandibular joint dysfunction (TMD) and 210 controls (control group) for the following Research Diagnostic Criteria (RDC) Axis II biopsychosocial factors: depression, pain grades, and unspecific physical symptoms with and without pain, and to determine whether certain genetic polymorphisms increase susceptibility to these factors. Methods: RDC Axis I was used for diagnosing myofascial pain in the cases. Cases and controls answered the RDC Axis II questionnaire. The DNA of cases and controls was collected and quantified. Ancestry-informative markers were identified followed by polymorphism analysis of the genes NR3C1, CHRM2, TPH1, and MC1R using TaqMan Low Density Array (TLDA) personalized cards. Results: Polymorphisms of the genes NR3C1, CHRM2, TPH1, and MC1R were not associated with depression, pain, unspecific physical symptoms with and without pain, ancestry-informative markers, or TMD. Conclusions: The multifactorial polygenic mechanism of susceptibility is based on the idea that each gene contributes with small, additive, and relatively equal effects. Hence, it is possible that the study genes have more effective interrelations with other predisposing and regulatory genes, but in isolation they do not have enough biological and statistical consistency to explain TMD. By extension, the small number of Blacks, Natives, and Asians in this sample also corroborate to the weak association between these ethnicities factors and genetic polymorphisms. Larger studies, such as the ones currently being conducted by our group, can elucidate the associations postulated above more clearly.
