Backgrounds: Intentional replantation (IR) is a reliable and predictable treatment option for cases with failed non-surgical root canal treatment. The success of IR is found to be 52–95%. The current case is of 35years old female who presented with severe pain and swelling in lower right first mandibular molar with previously initiated non-surgical root canal treatment that resulted in instrument separation in mesio-buccal canal. Periapical radiograph showed rarefactions at furcation area, mesial and distal root apices. It was decided to complete the non-surgical root canal treatment followed by intentional replantation and retrograde filling with MTA. The tooth was found to be asymptomatic after two years follow up and periapical radiographs depicted complete healing. Intentional replantation with careful case selection is a successful, easy and reliable treatment option for hopeless cases. Atraumatic extraction, minimum extra-alveolar time and aseptic techniques during the procedure are the key factors for success of the procedure.

Most common form of dental trauma in children are the fractures of crown mainly in anterior teeth. A case of complicated crown fracture treated with Cvek pulpotomy using MTA followed by fragment re-attachment with careful follow-up is presented here. Tooth fragment re-attachment provides feasible conservative alternative approach to restore esthetics and tooth function. Successful outcomes have been shown by the long term follow up of the treatment with the preservation of pulp vitality and continued development of root. Clinical results have also shown good esthetics and functional results of presented technique.

OBJECTIVES: To correct dental origin anterior crossbite by placement of Glass Ionomer cement occlusal stops on mandibular first permanent molars for maximum of two weeks. METHODOLOGY: 16 patients (age: 7-11 years) with dental anterior crossbite were treated by placement of Glass Ionomer cement occlusal stops on mandibular first permanent molars for maximum of 2 weeks to create 1mm anterior open bite. The patients were then recalled after 1 month, 3 months and 6 months for follow up visits. Fisher’s exact test applied using SPSS version # 25. RESULTS: 13 out of 16 patients were treated successfully within two weeks of placement of occlusal stops. Follow-up at six months showed no relapse in any of the corrected cases. CONCLUSION: Placement of glass ionomer cement occlusal stops for two weeks on mandibular first permanent molars is an easy approach to correct dental anterior crossbite.

Background: Improving our clinical skill and training through the scientific evidence is essential so that one can provide the highest quality of care to the patients. In both, endodontic and restorative procedures, proper isolation is very essential prerequisite for its long term success. Rubber dam is considered as a gold standard for isolation in dentistry hence its preclinical training to dental students is of uttermost importance. Aim: To evaluate the knowledge and attitude of dental students in regard to placement and usage of rubber dam Methodology: This is a questionnaire based descriptive cross-sectional study that was conducted on the third, fourth and fifth year undergraduate dental students at Qassim University College of Dentistry. The questions were based on knowledge and attitude of participants regarding the practicality of rubber dam use. Data was organized and analyzed by utilizing Statistical Package for the Social Sciences (SPSS) version 23.0. Results: Overall response rate was 59.5%. Around 97.7% of the students agreed upon the importance of using rubber dam. 92% gave positive response regarding use of rubber dam in future restorative and operative cases while 72.7% were willing to gain knowledge about rubber dam through workshops and seminars. Conclusion: This study reaffirms the need for educational methods to be formulated to improve the attitude of dental students towards the used of rubber dam during undergraduate training and after graduation KEYWORDS: Attitude, Knowledge, Dental Students, Rubber dam
