Objective: The aim this study was to check the accuracy of paper point technique for final working length measurement after canal preparation. Study Design: Randomized controlled trial Place and Duration: Study was performed in department of operative dentistry, Liaquat University of Medical & Health Sciences, Jamshoro for one year duration from January 2017 to December 2017. Methodology: This study was performed on 78 patients divided equally into two groups. In one group working length was established by using electronic apex locator while in second group working length was established by using electronic apex locator with paper point technique. To check the working length master apical gutta percha point (GP point) was inserted into canal and radiograph were taken by paralleling angle technique. Results: There were 34 (43.6%) males while 44 (56.4%) patients were females. Mean age of patients was 30.5±8.9 years. Mean tooth number was 28.8±11.0. Group A is concerned that was treated only with Electronic Apex Locator showed lesser number of acceptable length than group B. on the other hand, group B was treated with electronic apex locator and paper point technique showed higher acceptable length of respondents with a difference of 4 frequencies or 7% in excess. A less value of chi-square test showed relationship between observed and expected data; whereas, significance value indicated no significant difference between group A and B. Conclusion: Paper point technique is as reliable as other techniques for final working length measurement. Key Words: Electronic Apex Locator, Paper Point Technique, Endodontic Working Length
Objective: To assess the effect of 5% sodium fluoride (NaF) varnish application in prevention of caries in mixed dentition rural Jamshoro school children over the course of 6 months. Methods: children with lower stage caries aged 7 to 10 years were included. Students were equally divided in two groups. In Group-A students, 5% fluoride varnish was applied. While in children of control group necessary instructions were given to the student about dietary control. After 3 months, varnish applied teeth on both group’s children were examined again and the rate of caries were documented by using DMFT. After 3 months fluoride varnish was applied to both groups using same method and same directives. Dental caries was examined using the DMFT score after six months of application of fluoride varnish in both groups. All the data was recorded in the proforma. Results: In this study total 108 children were studied, there was no significant difference according to age and brush frequency among both groups p-value 0.146 and 0.088 respectively. Most of the children were using brush among both groups. A starting of the trail mean of DMFT was 1.22+0.24 in group A and 1.39+0.56 in group B. After 3 months it was almost equal among both groups as, while on six months assessment DMFT was raised in control group in contrast to test group p-value 0.012 Conclusion: It was concluded there was significant preventive effect/impact of fluoride varnish on dental caries. DMFT was raised in control group during 6 months rather than test group. Keywords: Children, Dental caries, Fluoride varnish
Objective: To compare the clinical efficacy of 2.5% non-heated sodium hypochlorite and 2.5% heated sodium hypochlorite as irrigation to control postoperative pain in single visit root canal treatment. Study Design: Comparative analytical study Place and Duration: Operative dentistry department of Liaquat University of Medical and Health Sciences, Jamshoro for 6 months duration from March 2017 to September 2017. Material and Methods: A total of 60 patients with single rooted maxillary and mandibular permanent teeth were randomly allocated into two groups. 30 patients were in group A and treated with non heated sodium hypochlorite solution and 30 patients in group B were treated with 2.5% heated sodium hypochlorite solution. In both groups, the level of pain was measured postoperatively after 48 hours by using Heft Parker visual Analog Scale of 10 and information was collected on Performa. Results: The average age of the patients was 28.62±6.06 years. There were 40(66.7%) male and 20(33.3%) female. Pain was reduced in both groups but there were no significant difference in reduction of pain between groups (p=0.640). Conclusion: Severity of pain was not statistically significant between groups. At 48 hours, Pain was reduced in both groups but there were no significant difference in reduction of pain between groups. Heated sodium hypochlorite to relieve postoperative pain, it should be new trend for recommendation for treatment of irreversible pulpitis in single visit root canal treatment. Key Words: Root canal, Heated sodium hypochlorite, Postoperative pain.
