This equivalence, randomized, clinical trial aimed to compare the postoperative pain of root canal therapy (RCT) with pulpotomy with mineral trioxide aggregate (PMTA) or calcium-enriched mixture (PCEM) in permanent mature teeth. In seven academic centers, 550 cariously exposed pulps were included and randomly allocated into PMTA (n = 188), PCEM (n = 194), or RCT (n = 168) arms. Preoperative “Pain Intensity” (PI) on Numerical Rating Scale and postoperative PIs until day 7 were recorded. Patients’ demographic and pre-/intra-/postoperative factors/conditions were recorded/analysed. The arms were homogeneous in terms of demographics. The mean preoperative PIs were similar (P=0.998), the mean sum PIs recorded during 10 postoperative intervals were comparable (P=0.939), and the trend/changes in pain relief were parallel (P=0.821) in all study arms. The incidences of preoperative moderate-severe pain in RCT, PMTA, and PCEM arms were 56.5%, 55.7%, and 56.7%, which after 24 hours considerably decreased to 13.1%, 10.6%, and 12.9%, respectively (P=0.578). The time span of endodontic procedures was statistically different; RCT = 69.73, PMTA = 35.37, and PCEM = 33.62 minutes (P<0.001). Patients with greater preoperative pain, symptomatic apical periodontitis, or presence of PDL widening suffered more pain (P=0.002, 0.035, and 0.023, resp.); however, other pre-/intra-/postoperative factors/conditions were comparable. Pulpotomy with MTA/CEM and RCT demonstrate comparable and effective postoperative pain relief.

Introduction:Copper IUD is a long term and reversible contraception which equals tubal ligation in terms of sterilization. One of the barriers to using this contraception method is the fear and the pain associated with its insertion. Eutectic mixture of local anesthetics (EMLA) 5% is a local anesthetic that contains 25 mg lidocaine and 25 mg of prilocaine per gram. Application of topical analgesic cream to the cervix for laser surgery, hysteroscopy and hysterosalpingography is knownAims:this study aimed to determine the effect of EMLA on IUD insertion pain.Methods:This triple blind clinical trial was conducted on 92 women in a clinic in Hamedan in 2012. After applying the cream on the cervix, pain in three steps, after using Tenaculum, after inserting hystrometr and after inserting IUD and removing IUD insertion tube were assessed with visual analog scale and were compared in EMLA group and placebo groupStatistical analysis used to determine and compare the pain of independent t tests, Mann-Whitney U test and repeated measures analysis of variance and chi-square tests to determine the homogeneity of variables and Fisher’s exact test was usedResults:Insertion hystrometr was determined as the most painful IUD insertion. The mean pain at step 2 (inserting hystrometr) was (3/11±2/53) in EMLA group, (5/23±2/31) in placebo group. EMLA cream significantly reduced the pain after using tenaculum (P<0/001), pain inserting Hystrometr (P< 0/001) and pain at IUD insertion and removing insertion tube (P< 0/001)Conclusions:Topical Application of EMLA 5% cream as a topical anesthetic on the cervix before insertion IUD reduced the pain during this procedure.

The objective of the current study was to compare the anaesthetic efficacy of supplemental intraligamentary (IL) injection of 4% articaine with that of 2% lidocaine in the mandibular first and second molars with irreversible pulpitis after an ineffective inferior alveolar nerve block injection (IANB) using the same anaesthetic in a randomised triple-blind clinical trial. Seventy-six adult patients, who were diagnosed with irreversible pulpitis in the mandibular first or second molars, were divided into 2 groups and received IANB randomly. In patients with lip numbness, anaesthesia was evaluated with the cold and electrical pulp (EPT) tests, and if the reported number on EPT was below 100, supplemental IL injection was administered using the same anaesthetic. The teeth were retested after 5 minutes. The Heft–Parker visual analogue scale was used to evaluate pain after IANB and IL injections. Statistical analysis was performed using repeated measures ANOVA, chi-square, and independent-sample and paired-sample t-tests. The results showed that there was no significant difference in the success rates of supplemental IL and IANB injections between articaine and lidocaine. Furthermore, there was no significant difference in the success rates of supplemental IL injection with lidocaine between the mandibular first and second molars. However, there was a significant difference in the success rates of supplemental IL injection with articaine between the mandibular first and second molars. Moreover, supplemental IL injections indicated no significant difference in the anaesthetic efficacy between articaine and lidocaine; nevertheless, they were more effective in the mandibular second molars, especially with articaine.

Objective: Because of the significant prevalence of diabetes, disability of patients due to the complication of Diabeti Neuropathy (DN) has been increased. Physiotherapy is one of the methods for DN which can help control the symptoms through modalities such as infrared radiation, electrical stimulation and electromagnetic fields. Tecar therapy is a form of electromagnetic fields.This study investigated the effect of Capacitive Tecar therapy on pain and tactile sensation of the feet in type 2 diabetics with symptoms of peripheral neuropathy. Materials & Methods: This clinical trial was performed as pre-test and post-test with a control group. The samples consisted of 24 diabetics aged 17-78 years with symtoms of peripheral neuropathy allocated in the control and experimental group randomly. The patients of experimental groups participated in 10 sessions and received the Capasitive tecar therapy with 10%-30% intensity in addition to infrared radiatin; the controls received the same protocol with zero intensity of tecar. Pain and tactile sensation of the soles were evaluated before and after sessions. The collected data were analyzed by the Reapeted measure Analysis Of Variance (ANOVA). All statistical analyses were performed in SPSS V. 18. The significance level was set at P<0.05. Results: The results of Rearetd Measure ANOVA showed that there was a significant difference in the mean scores of pain and tactile sensation of soles in the post-test compared to the pre-test of two groups.(P<0.001).There was also a significant difference in the means of post-test scores of variable pain (P=0.002) and tactile sensation (P<0.001) between the two groups. The improvement of variables in experimental group was more than control group. Conclusion: The results of this study revealed that Tecar Therapy with infrared radiation can be an appropriate therapeutic program for improving pain and tactile sensation of soles in diabetic patients with symptoms of peripheral neuropathy.

Purpose: Developmental dysplasia of the hip (DDH) increases the risk of secondary degenerative changes and subsequent total hip arthroplasty. The postoperative quality of life in patients with DDH who have been born and grown with this disability and adapted to it during the life, is one of the most challenging issues. This study aimed to compare the quality of life of patients with DDH before and after total hip arthroplasty (THA) operation. Methods:This research has a quasi-experimental/interventional design. A group of 20 patients with DDH, who underwent THA operation in Akhtar and Shafa yahyaiyan hospitals, were evaluated before operation and 6 months after it using SF36 quality of life questionnaire. Results:Findings showed significant improvement in all SF-36 subscales scores, including physical function, role physical, role emotional, vitality, mental health, social function, bodily pain, general function, and general health as well as total score (P=0.002). SF-36 mean(SD) scores before and after surgery was 27.41(22.75) and 79.12(28.03), respectively. Conclusion:THA operation improves the quality of life of patients with DDH.
