Objective: The purpose of this study was to determine postoperative pain after root canal therapy performed with hand files versus R-Endo rotary instruments.
Methods: Eighty single-rooted teeth were included in this study. Patients without preoperative pain were randomized by minimization program into two groups. The standardized protocol for all teeth involved local anesthesia, isolation, access and irrigation with 2.5% NaOCl. Root canal fillings of the teeth in group 1 were removed by Headstroem files; and, in group 2 removal was performed via R-Endo rotary instruments. Both groups were medicated with calcium hydroxide and then closed with a temporary filling material. At 4, 8, 12, 24 hours and 2, 3, 4, 5, 6, 7 days, patients recorded postreatment pain levels. Data were statistically analyzed using the chi-squared and Fischer exact tests.
Results: There was a statiscal difference in postoperative pain incidance between the groups. Postoperative pain levels were significantly higher at 4th hour and 1st, 5th, 6th and 7th days in hand file group. There was no significant difference in the occurrence of flare-ups between the groups.
Conclusion: R-Endo rotary system was found to be effective in reducing postoperative pain in retreatment cases.

CASE REPORT
2. Management of non-vital anterior teeth with open apex: A report of two cases

Treatment of teeth with open apex requires careful handling and diligence in clinical practice. Prognosis of endodontic treatment in such cases is directly related to the quality of apical obturation. Previously, a calcified barrier using calcium hydroxide treatment was recommended as an approach for these cases however due to various drawback of this method, current management approach suggests apexification through an apical plug at the apical segment.This report describes two cases of apexification of upper left incisor using mineral trioxide aggregate plug. After two year follow up, both teeth are clinically and radiographically asypmtomatic and the healing of the apical area is visible.

Invasive cervical resorption (ICR) is a relatively uncommon form of external root resorption. The lesion is mainly detected on radiographs and exhibits no external signs. The radiographic appearance of ICR is an asymmetric radiolucent lesion with irregular margins and an unchanged root canal. Clinically, it usually begins on the cervical region of the root surface and may appear as asymptomatic pink discoloration of the tooth called “pink spot”. The most commonly reported predisposing factors include traumatic dental injuries, orthodontic treatment, orthognathic surgery, periodontal diseases and treatments, and intracoronal bleaching. This paper reports the management of maxillary right central incisor diagnosed with external ICR using Biodentine with a multidisciplinary approach.

4. Unusual variant of type 3 dens invaginatus in a maxillary lateral: A rare case report

Dens invaginatus is a developmental anomaly resulting from epithelial invagination into the dental papilla. The etiology of the dens invaginatus malformation remains undefined. The most commonly affected tooth is the maxillary lateral incisor followed by the maxillary central incisor. Endodontic treatment of teeth with dens invaginatus can be highly complicated due to anatomical challenges. Treatment options include nonsurgical treatment of the main canal and invagination, endodontic surgery, a combination of these techniques, intentional replantation and extraction. This case report presents the successful nonsurgical endodontic treatment of a maxillary right lateral diagnosed with an interesting type III dens invaginatus and communicated extensive periapical lesion. The results obtained after five years of clinical and radiographic follow-up demonstrated that conventional endodontic treatment is a clinically viable alternative in cases of type III dens invaginatus.
