Aim: The rate of healing of periapical lesion after the antibacterial dressing with triple antibiotic paste and calcium hydroxide was assessed. Materials and Methods: Case reports which used triple antibiotic paste and calcium hydroxide as the intracanal dressing was searched in PubMed, Google Scholar and Cochrane Oral Health's Trials Register up to August 2020, without language and period restriction. Two authors independently reviewed all identified titles and abstracts for eligibility. Tables were generated to summarize the included studies. Results: Sixteen ( n = 16) articles met the eligibility criteria. Nonsurgical endodontic treatment was carried out in eleven cases with triple antibiotic paste and in nineteen cases calcium hydroxide was used. Results of the study after analyzing the case reports indicate that both triple antibiotic paste and calcium hydroxide are equally effective as intracanal medicament. In cases where calcium hydroxide failed to eliminate symptoms, triple antibiotic paste was found to be effective. Conclusion: As far as the effect on the healing of the periapical lesions is concerned, all the studies showed a high success rate. Available scientific data indicates nonsurgical treatment can be adopted as a routine measure to conservatively treat large periapical lesions of endodontic origin.

BACKGROUND: The cytotoxicity of Sodium hypochlorite has always been a concern when used as an endodontic irrigant. Quest for an equally effective, but less toxic substitute has led to researches on Calcium hypochlorite (Ca(ClO)2 ) solutions. But it has been proven that 10% Calcium hypochlorite solution at room temperature (250 C) demonstrated slower rate of tissue dissolution than Sodium hypochlorite. Aim: This study was performed to assess if preheating enhanced the tissue dissolution capacity of 10% Ca(ClO)2 . MATERIALS AND METHODS: Human pulp tissue was obtained from freshly extracted single rooted mandibular premolars. The tissue weight was standardized to 9.5mg. The test groups consisted of freshly prepared Ca(ClO)2 solutions at room temperature (250 C), 450 C and 600 C. Ten specimens were assigned to each group with each specimen immersed in 2ml of the test solution. Five specimens immersed in normal saline made the control group. Every five minutes the tissue was retrieved, blotted dry, weighed and immersed back in fresh 2 ml of solution. This was continued for 60 minutes or till complete dissolution. The percentage difference in weight at each interval was calculated. The values obtained were statistically analyzed using one –way ANOVA. Intergroup comparison at different time intervals was done using Bonferroni test. RESULTS: Ca(ClO)2 solution at 600 C dissolved the tissue significantly faster than other solutions. The tissue dissolution rate of solution at 450 C was greater than that at 250 C. (P< 0.05) CONCLUSION: Within the limitations of this study, it can be concluded that preheating 10% Ca(ClO)2 solution significantly enhanced its tissue dissolution capacity.

Introduction: Low level lasers have an average output power range between 5 and 500 mW. Low level lasers have shown nonthermal, and bio-stimulatory effects. The most common complication of single visit endodontics is a flare-up that results in pain and swelling. Aim:The aim of this clinical study was to evaluate the effect of Low Level Laser Therapy in pain management after single visit endodontic treatment pain. Materials and methods: Thirty subjects with symptomatic apical periodontitis in their lower premolars were divided randomly into 3 groups. Group A was administered Low level Laser for 5 minutes prior to the procedure at the apex of the tooth through buccal mucosa and into the canal after pulp space preparation. Group B was given 600 milligrams of ibuprofen half an hour prior to the start of the treatment and given Low level Laser just prior to the treatment and into the canal after the completion of pulp space preparation. Group C was kept as a control group which was neither given analgesics nor laser preoperatively.Intensity of pain after treatment was noted down on a visual analog scale at four hour, eight hour,twelve hour and twenty four hour interval. Results: Results were obtained after statistical analysis. Conclusion: LLLT group showed less pain levels than the control group after single visit endodontics.
