BackgroundRhythmic joint mobilizations (RJM) of the temporomandibular joint (TMJ) are employed to relieve pain and improve function in patients with temporomandibular disorders (TMD). However, the evidence on the immediate effects of RJM in patients with TMD is scarce. The aim of this study was to assess the immediate clinical and functional effects of RJM in patients with TMD.Materials and methodsThis was a one-group quasi-experimental before and after study. Thirty-eight patients with TMD were assessed by means of pain intensity (visual analogue score, VAS), pressure pain threshold (PPT, measured through pressure algometry on the masseter and temporal muscles), mouth opening (MO, measured with a ruler), and surface electromyographic activity of the masseter and temporal muscles (asymmetry index, AI). Measurements were performed before and after a single, 1-min session of RJM of each TMJ. All statistical analyses were performed using the SPSS version 20.0 statistical package.ResultsA statistical significant difference was found in pain intensity, PPT and MO after the intervention (p < 0.05). No difference was found in the AI. A large effect size was observed for pain intensity, PPT of the left and right masseter muscles and MO (d = 0.85–1.13), whereas for the left and right temporal muscles the effect size was moderate (d = 0.62) and small, respectively (d = 0.49).ConclusionIn this sample of patients with TMD, a single session of RJM of the TMJ seemed to be effective in reducing pain intensity, increasing PPT and improving MO immediately after the intervention, without differences in the AI.  相似文献

Severe pain experienced by patients with oral submucous fibrosis (OSMF) compromises their physiotherapy and negatively affects the surgical outcome and the patient’s compliance. The main aim of this study was to develop a protocol for pain control in the management of OSMF postoperatively. This was a prospective, parallel with active control, double-arm, triple-blinded, randomised control trial (RCT) with 48 OSMF patients, randomised into two groups - Group A (control, n = 25): received non-opioid analgesics (NSAIDs) and Group B (cases, n = 23): received transdermal fentanyl patches (TFP). Pain and interincisal opening were measured on postoperative days 1, 3, 5, 7, 9, and 15, and on the1st and 3rd postoperative months. Quality of Life (QoL) was assessed preoperatively, on the 15th day postoperatively, and 3rd month postoperatively, and compliance was documented postoperatively on the 9th day. The transdermal fentanyl patch was found to have statistically significantly more effect in controlling severe pain during active mouth opening exercises, and thus significantly increased the patients’ compliance. Although there was increased mouth opening and QoL in the fentanyl group, the differences were statistically insignificant. Our study recommends the use of TFP for better pain control and compliance in postoperative OSMF patients.  相似文献

Introduction: Human papillomavirus (HPV) causes the most common sexually transmitted infection (STI) in the world. It affects people regardless of gender and age, causing genital warts and cancer. Objective: To evaluate university students’ knowledge of HPV and its relationship with head and neck and oral cancers. Methods: This is a cross-sectional study using an online questionnaire administered to undergraduate students at a public university (n=335). Results: In total, 69.3% of the participants were unaware of the relationship between HPV and head and neck cancers and 34.6% claimed that HPV may not cause oral cancer.  The chances of knowing about the relationship of HPV with head and neck cancers were significant for participants who knew that HPV could be asymptomatic (OR = 9.9; p = 0.029), that might cause genital warts in men (OR = 4.0; p = 0.015), and those aged 24 years or older (OR = 1.9; p = 0.021). However, undergraduate students in the field of health and medicine (OR = 0.419; p = 0.002), who had sex at least twice a week (OR = 0.471; p = 0.017), and were unaware of the target public for the HPV vaccine (OR: 0.222, p<0.001) were less likely to know about the relationship. Students who knew of the relationship between HPV and female (OR = 3.6; p = 0.010) and male genital warts (OR = 3.0; p = 0.005) or were immunized (OR = 1.8; p = 0.020) were more likely to understand the viral interaction with oral cancer. Those who were unaware of the population eligible for HPV vaccine (OR = 0.493; p = 0.017) also showed gaps in their knowledge of this relationship. Conclusion: Our findings showed that there were limitations in the knowledge about HPV, its vaccine, and its relationship with head and neck and oral cancers.  相似文献

Objective: Considering that oral microbiota might modulate immune responses, we explored if customary oral care procedures might influence immune-driven diseases such as asthma. Methods: This was a retrospective, cross-sectional analysis of responses to a self-completion medical questionnaire applied to subjects entering into college and high school programs during 2006–2011. Results: Responses from 329?780 students aged 14–24 years (97.6% of the original population) were analyzed. The prevalence of lifetime asthma was 4.01%. Subjects with asthma were slightly older, taller and heavier than subjects without asthma, and these differences were equally present in males and females. Subjects currently having two or more decayed teeth had asthma less frequently than those with one or none decayed tooth, with an odds ratio (OR)?=?0.86 and 95% confidence interval (95% CI) 0.83–0.89. In contrast, asthma was reported more frequently among students having two or more missing or filled teeth [OR?=?1.1 (95% CI 1.04–1.17) and OR?=?1.05 (95% CI 1.01–1.09), respectively]. From 2008 onwards, subjects also responded questions about oral hygiene incorporated into the core questionnaire. In these subjects, the use of toothpaste as well as the frequency and duration of toothbrushing were unrelated to asthma; regular use of mouthwash was associated with asthma in women [OR?=?1.16 (95% CI 1.07–1.25)], but not in men [OR?=?1.04 (95% CI 0.96–1.13)]. Results of multiple logistic regressions were in line with these findings. Conclusions: Our results suggested that oral hygiene and dental status could be novel factors influencing asthma development, and thus further studies to confirm and clarify this association are warranted.  相似文献

IntroductionAdenoid cystic carcinoma is the most frequent malignant tumor of the submandibular gland and the minor salivary glands. It is a malignant neoplasm that, despite its slow growth, shows an unfavorable prognosis.ObjectivesThe aim of this study was to perform a systematic review of the literature on Adenoid cystic carcinoma in the head and neck region and its clinicopathological characteristics, with emphasis on the perineural invasion capacity of the tumor.MethodsA systematic search of articles published between January 2000 and January 2014 was performed in the PubMed/MEDLINE, SciELO, Science Direct, and Scopus databases.ResultsNine articles were selected for this systematic review. These demonstrated that the female gender was more often affected and that malignant tumors showed a high rate of distant metastasis, recurrence, and a low survival rate. The presence of perineural invasion ranged from 29.4% to 62.5% and was associated with local tumor recurrence.ConclusionAdenoid cystic carcinoma is commonly characterized by the presence of pain, high rate of recurrence, metastasis, and a low survival rate. Reporting studies with patient follow-up is of utmost importance for a better clinical-pathological understanding and to improve the prognosis of this pathology.  相似文献
