According to researches, premolar extraction and anterior teeth retraction result in temporomandibular joint disorder due to posterior position of mandible. The aim of this study was to evaluate the effect of premolar extraction on TMJ disorder. In this interventiond study, 4 groups (10 patients for each group) were treated.They were classified as 1- non extraction, 2- extraction of two upper first premolars, 3- extraction of four first premolars, 4- combined extraction groups. Helkimo scores were evaluated before treatment, after treatment, one and two years after treatment. The results were analyzed with ANOVA and paired t-test. At the end of the treatment and two years after treatment in comparison with before treatment, Helkimo score had Significant differentce in all groups (PO.001). In the second year after debanding in comparison with the first year after debanding, no significant differences were seen in each group. No significant difference was seen between the four groups in the final appraisal of TMD. It seems that extraction had no adverse effect on TMD.

  Background and Aims: Temporomandibular joint disorders are common problems among patients referring to dental schools and clinics. However appropriate treatment modalities are performed for the TMD patients in dental school, the results and success rate of these treatments are not studied distinctly. The aims of this study was to determine the treatment performed for temporomandibular patients at the TMJ department of Tehran University dental school in 2010-11 .

  Materials and Methods: In a descriptive cross-sectional trial, 85 TMD patients treated at the TMJ department of Tehran University dental school were examined at least 3 months after the treatments. The patients demographic data ,TMD signs and symptoms and the improvements occurred in TMD disorder were determined (complete, partial and no improvement). The patients satisfaction regarding the treatment results were investigated and data were analyzed regarding the presence of different TMD signs and symptoms before and after the treatment using Mann-Whitney U test .

  Results: TMJ pain (35 cases, 42.2%), click (33 cases, 39.8%) and muscle tenderness (26 cases, 31.3%) were the most prevalent obtained signs and symptoms. The mean age of the patients were 32.3 years old while females were the predominant group (72 cases vs.11 one). 44 individuals (53.0%) were treated by splint, 11 ones (13.3%) with anterior repositioning splint and 17 individuals (92.5%) were managed by physiotherapy plus splint. 65 patients (87.3%) were satisfied with the results and 16 ones (19.3%) were not. After the treatment, patients with TMJ pain (P<0.001) and muscle tenderness (P<0.001) showed significantly lower satisfaction than that of patients with no signs. No other significant differences were noted between patients satisfaction regarding the presence of TMD signs and symptoms (P>0.05) .

  Conclusion: The results showed that the treatments presented for the TMD patients at Tehran University dental school were successful and most patients received satisfactory treatment.

Background and Aims: Headache is among the most common complaints in patients suffering from temporomandibular joint disorders (TMD). Thus, it seems that evaluation of patients with headache in terms of temporomandibular joint (TMJ) disorders is necessary. In people with TMD, parafunctional activities play an important etiologic role. Considering the high prevalence of bruxism and TMDs in patients with headache, assessment the accuracy and severity of this association can play a key role in diagnosis and treatment of these two phenomena. The purpose of this study was to investigate the relationship between bruxism, TMD and headache, also assessment the efficacy of TMD conservative therapy with a special approach to self-management in treating patients with headache.
Materials and Methods: Motor searches of Cochrane, Medline and EMbase databases, PubMed, Google Scholar, Uptodate, BMJ clinical Evidence, MD consult and science direct by using of relevant key words were searched for article published between 2000 and 2015. A total of English language abstracts were reviewed, 80 full articles were obtained and among them, 30 relevant articles were reviewed in this study. Because of the high number of studies in this field, we divided the data into four group, bruxism and TMD, TMD and headache, bruxism, TMD and headache, treatment.
Conclusion: Bruxism and temporomandibular disorders are the two main contributing factors in initiation and perpetuation of headache. Treatment of these two phenomena would be effective in the treatment of headache.

Background and Aims: Temporomandibular joint disorders (TMDs) are one of the most common causes of the patient's referral to dental clinics. Considering the role of related factors in its creation, the purpose of this study was to investigate the relative frequency of factors related to temporomandibular disorders in patients aged 20 to 50 years referred to dental clinics in Isfahan in 1397.
Materials and Methods: In this descriptive and analytical study, 324 patients referred to Isfahan dental clinics in 1397 were randomly included. Factors related to TMD and demographic factors of patients were recorded with clinical examination by a trained dentist and self-declaration of patients in the data collection form. The frequency and relevance were analysed by SPSS 22 software and chi-square, fisher and logistic regression statistic tests.
Results: At least one of the TMD related factors was present in 40.7% of the subjects, which the most common factors related to TMD was posterior edentulousness (49.7%). History of jaw dislocation was more common in men (P=0.014) and the frequency of posterior edentulousness was more common in in women (P=0.003). As the age increased, the frequency of posterior edentulousness (P=0.000) and earache (P=0.009) increased. The frequency of posterior edentulousness was higher in housekeepers (P=0.000), the frequency of earache was higher in employees (P=0.005) and the history of jaw dislocation was higher in self-employed persons (P=0.047).
Conclusion: The high prevalence of TMD and related factors, such as a history of jaw dislocation, posterior edentulousness, earache, and clenching, requires attention to be identified and treat these problems.
