Aim: Light units used for polymerization of resin composites are subject to deterioration with age, and frequent maintenance is required to maintain optimal efficacy. The aim of this study was to examine the efficacy of LED units in private dental offices in Baddi (H.P) for polymerization of resin composites. Materials and Methods: Twenty dental offices met all selection criteria and agreedto participate in the study. To measure light intensity, an analogue radiometer was used. The probe of each LED unit was placed and then measurements of light intensities were recorded for each light unit and the data was statistically analysed. Results: The light intensity of the individual units varied widely. The results revealed that there was error of 35% and a standard deviation of 155.76 among the intensities of various LED Units checked in the study. Conclusions: Light polymerization units in private dental offices displayed a wide rangein light intensity, and many had below-recommended levels. A positive linear relationship was found between light intensity and photoactivation effectiveness. Dentists should regularly monitor the condition of light units and replace deteriorating parts.

Successful management of furcation perforations poses a challenge for a clinician. The perforation can result from iatrogenic causes, caries or resorption. It is advisable to repair the perforation as soon as it is identified, since any delay allows the bacterial ingress leading to a complicated endodontic–periodontal lesion and ultimately in the treatment failure. This case report describes successful management of a furcal perforation in a mandibular first molar, which was repaired using Biodentine. The endodontic treatment was completed and the tooth was coronally restored with composite followed by full coverage restoration. Two years follow up of the case showing absence of pain; periradicular healing of the lesion, along with functional tooth stability indicated a successful outcome of endodontic treatment and sealing the perforation using Biodentine.

Aim: The purpose of this study was to determine current trends in irrigation practice among the practicing dentists in Himachal Pradesh. Methodology: A self prepared questionnaire comprising of 15 questions was e-mailed to 1970 members of the State Dental Council of Himachal Pradesh. The information gathered was the individual irrigant selection, irrigant concentration, smear layer removal, and use of adjuncts to irrigation. Results: A total of 544 replies were evaluated thus making the response rate of 27.6% for the study. Our data indicated that 38% of respondents primarily use sodium hypochlorite, with 61% of them using it at a concentration >5.0%. Only 21% of respondents aimed to remove the smear layer during endodontic treatment with only 7% using an adjunct to irrigation. Antibacterial activity was rated as the most important reason while selecting an irrigant. Conclusion: In spite of the crucial nature of the irrigation step in the endodontic therapy, the results of the study were not very satisfying especially when it comes to the use of adjuncts or newer irrigating systems. Thus there is need to regularly update and gauge the practices adopted by dental practitioners in the state.

Introduction: This study was conducted to evaluate clinical and radiographic findings induced by revascularization with and without platelet-rich plasma (PRP). Methods: Twenty patients with nonvital, immature anterior teeth were randomly categorized into 2 groups. Subsequent to minimal instrumentation of the root canal, disinfection was achieved with ledermix paste and followed by revascularization with and without PRP in groups 1 and 2, respectively. The cases were followed up clinically and radiographically at 6- and 12-month intervals. Results: Clinically, all cases were asymptomatic with complete resolution of signs and symptoms (except four cases which were considered as dropout). Radiographically, there was no significant difference in periapical healing, apical closure, and dentinal wall thickening in group I in comparison with group II. However, root lengthening was comparable for both of the procedures. Conclusions: Revascularization is a conservative and an effective method for inducing maturogenesis in nonvital, immature teeth. Supplementations with PRP can potentially improve the desired biological outcome of this regenerative procedure.

Purpose: Prevention and management of postendodontic pain (PEP) is an integral part of endodontic treatment. NSAIDs such as Ibuprofen, Ketorolac are the most common medications used for managing pain after root canal treatment. So the purpose of this study was to compare the effect of pain relief on regular versus on demand prescription of ibuprofen after single-visit root canal treatment in teeth with irreversible pulpitis. Materials & Methodology: The study was performed on twenty patients. Root canal treatment was performed and all the patients were given a ‘‘rescue bag’’ that contained 8 tablets of 400 mg ibuprofen and then divided into two groups. In the group 1- patients were instructed to use ibuprofen tablets if they felt pain and in the group 2- patients were instructed to take ibuprofen regularly after every 6 hours for at least three days. Patients were instructed to complete a form to rate their pain at 24 and 48 hours after the root canal treatment and were also asked to record the number of analgesic tablets they had taken. Records were collected and statistically analysed. Results: The patients’ pain levels in groups 1 and 2 were not significantly different at 24 and 48 hours after root canal treatment. The number of analgesic medications used by the patients in group 2 was significantly higher than the other group. Conclusion: Regular prescription of ibuprofen had no significant effect on postoperative pain compared with on-demand use of ibuprofen in teeth with irreversible pulpitis
