Aim: The primary objective of any pulp therapy is to maintain the integrity and health of a tooth and its supporting tissue as well as to maintain arch length and space maintenance. The aim of this case is to a probate and popularizes the technique of vital pulpotomy in primary teeth with biodentin. Update Dent. Coll. j: 2015; 5 (2): 57-62

This case report describes a case of avulsed left maxillary central incisor tooth which was replanted in the dental office. The tooth was gently rinsed of any debris and placed in normal saline during the examination and preparation of the replantation socket. The tooth was replanted and functionally splinted. The following week the tooth was opened for pulp extirpation and placement of calcium hydroxide. Two weeks later, the root canal was filled with gutta-percha and zinc oxide eugenol sealer, and the access cavity was restored with a bonded composite restoration; the splint was removed. Two year clinical and radiological follow up of the case showed ankylosis and infraocclusion of the replanted tooth Update Dent. Coll. j: 2015; 5 (1): 30-34

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.

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 re-attachment, good aesthetics and healthy periodontium.

Background: The greatest threats to developing teeth are dental caries and traumatic injury. If pulpal exposure occurs, then a pulpotomy procedure aims to preserve pulp vitality to allow for normal root development. Historically, calcium hydroxide has been the material of choice for pulpotomy procedures. Recently, an alternative material called mineral trioxide aggregate (MTA) has demonstrated the ability to induce hard-tissue formation in pulpal tissue. Objectives: This prospective study was conducted to observe the clinical and radiological findings of pulpotomies done with Mineral Trioxide Aggregate (MTA) &Calcium Hydroxide{Ca(OH)2} and to evaluate success rate of MTA in maintaining pulpal health in teeth with carious lesion. Materials and Methods: In this clinical trial study, 40 primary molars were treated by a conventional pulpotomy technique. They all fulfill the inclusion criteria and gave consent regarding this study. All selected teeth were evenly divided into 2 test groups. In group 1, the MTA pulpotomy (experimental) was performed, whereas in group 2, the conventional Ca(OH)2 pulpotomy (control) was done. The teeth of both groups were finally restored by Glass Ionomer Cement (GIC). The children were recalled for clinical and radiographic evaluations after 3, 6, and 12 months. Result: The follow-up evaluations revealed failure due to pain and swelling detected at 6 and 12 months postoperative evaluations in only 3 teeth treated with Ca(OH)2 and one treated with MTA. The remaining 36 teeth appeared to be clinically and radiographically successful 12 months postoperatively. Calcific metamorphosis was a radiographic finding in 4 teeth treated with MTA and 2 teeth treated with Ca(OH)2. Conclusion: Based on this clinical and radiographical evaluation study of 3, 6, and 12 months follow-up, MTA could be used as a safe material for pulpotomy in cariously and mechanically exposed primary molars and seems to be a suitable alternative to calcium hydroxide. Further research, however, is required to clarify this conclusion. DOI: http://dx.doi.org/10.3329/updcj.v3i1.17981 Update Dent. Coll. j: 2013; 3 (1): 24-31

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 non-surgical endodontic treatment. The tooth was functional without any complication on the basis of regular clinical and radiological evaluation. DOI: http://dx.doi.org/10.3329/updcj.v2i2.15534 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.
