Reattachment of a fractured fragment to the remaining tooth is challenging but one of the best treatment protocol in regards to aesthetics, function as well as patients acceptance. This case report presents a 20 years old male with an oblique complicated crown fracture of maxillary left central incisor tooth. The procedure used to repair the fracture regarding this case included flap surgery with endodontic treatment. The root canal was filled with a root canal sealer and gutta-percha. After root canal obturation, fragments were reattached with duel cure composite resin using a glass fibre post. After 12 months evaluation, clinical and radiographic examinations showed a stable reattachment, good aesthetics and healthy periodontium.
Objective: To evaluate the clinical and radiological outcome of MTA in nonvital teeth with open apices. Methods: Twenty-five non-vital teeth with open apices were treated with MTA apexification procedure. Standard endodontic procedures were followed and an apical plug of at least 5 mm was created by using MTA after a calcium hydroxide intra-canal dressing for at least 1 week. Final obturation was done after 24 hours by vertical compaction technique using gutta percha. Patients were recalled at 3, 6, 9 and 12 months interval. Clinical outcome was evaluated by assessing pain, tenderness, mobility and sinus tract. Blind to the treatment record, two examiners assessed the pre-treatment and post-treatment radiographs. Each radiograph was scored with the Periapical Index (PAI) and the size of the apical lesion was measured. The presence of an apical bridge over MTA was also noted. Results: Clinically 92% success rate was found whereas radiologically absolute success rate was 84%. Before treatment the mean PAI was 3.6 and mean size of the lesion was 3.24 mm. But, after 12 months follow up, the mean PAI was 1.36 and the mean lesion size was 0.68 mm. An apical barrier over MTA was distinguishable in 5 cases. Conclusion: Apexification using MTA can be considered as a predictable treatment option than calcium hydroxide apexification. DOI: http://dx.doi.org/10.3329/updcj.v3i2.17994 Update Dent.

Background: The presence of a single root canal in mandibular first premolar cannot be assumed always. The variability in canal morpholohy of root canal includes the number & shape of the canal as well as pathways of the canals. Methods: In this study, 100 mandibular first premolar teeth were evaluated by clearing technique. Collected teeth were cleaned and merged with 5.25% NaOCl for 48 hours. Then the teeth were decalcified with 5% nitric acid for 72 hours followed by dehydrated sequentially with 80-100% alcohol. After dehydration, Indian Ink was injected into the canal through the previously prepared access cavity. Finally the teeth were made transperent by 98% methylsalicylate and examined. Results: Out of 100 mandibular first premolar teeth, 89 were single rooted, 10 with double rooted and only 1 was triple. On evaluation of canal configuration according to Weine classification, mandibular first premolars had 64% type I, 5% type II, 22% type III and 9% type IV. Apical delta was found incase of 8% mandibular first premolar tooth. Conclusion: Based on this study, mandibular first premolar teeth of Bangladeshi population have multiple roots and canals and variable canal configurations.

The aim of this report is to discuss a case about a traumatized upper left central incisor presented with chronic periapical pathology with unusual presentation. In this case, the apical area of the tooth was exposed for a long period and the apex was open due to loss of affected tooth materials and its surrounding bone and soft tissue loss. The apical area was corrected with apical curettage and retrograde filling with Mineral Trioxide Aggregate (MTA) as well as soft tissue managed with pedicle flap design. The discolouration and mild shortening of the crown due to intrusive effect was managed by lamination of cosmetic restorative material. After 12 months follow up, the offending tooth was accepted both functionally and aesthetically. DOI: http://dx.doi.org/10.3329/updcj.v3i2.17998 Update Dent. Coll. j: 2013; 3 (2): 39-42
Background: Root canal Therapy is one of the procedures for the management of nonvital tooth with periapical lesion. The principle of this therapy is the complete sterilization of the total pulp canal space thereby healing of the periradicular lesion.
Objectives: This experimental study assessed the clinical and radiological outcome of root canal treatment for nonsurgical management of nonvital teeth with periapical lesion.
Materials and Methods: A total number of 40 infected teeth with periapical lesion were treated by conventional root canal treatment. Irritants from the root canal system was removed by mechanical instrumentation( Crown down Technique), chemical irrigation with NaOCL and by using Calcium Hydroxide as intracanal medicaments and fluid tight obturation both apically and coronally resulting repairs of inflamed periradicular tissues. The protocol for follow up examination will be 3, 6 and 12 months post operatively. At the time of follow up examination a standard follow up chart will be maintained.
Results: Among 40 cases 32 cases could be treated as acceptable as their responses were good both clinically and radiologically and 5 patients came back with some complications among them 3 cases were uncertain and 2 cases were unacceptable.
Conclusion: It was concluded that conventional root canal treatment reduced clinical signs and symptoms successfully in teeth with periapical lesion and radiologically.

Palato-gingival groove is a developmental anomaly often affecting the maxillary lateral incisor. The aim of this presentation is to describe the clinical management of a maxillary lateral incisor tooth with a palato-gingival groove with perio-endo lesion having immature apex. Despite complex anatomy, this case was managed by using Mineral Trioxide Aggregate plug technique with as a nonsurgical endodontic treatment. The tooth was functional without any complication on the basis of regular clinical and radiological evaluation.
IntroductionThe region in which the lateral incisors are located is considered to be an area of embryological risk.
