ABSTRACT
The consequences of injudicious use of orthodontic braces may vary from mild periodontal problems to severe loss of the attached periodontal tissues. In this case the patient had undergone orthodontic treatment. Though her appearance improved after the orthodontic treatment, but tooth # 16 which was banded and used for anchorage showed complete crestal and apical bone dehiscence in the buccal region. The patient came with the complaint of discomfort and inability to chew on the right side of maxilla. On intraoral examination, unusual calculus was seen deposited on the gums. X-ray showed resorption of buccal roots of tooth # 16. The patient was treated endodontically for the same tooth as it was grossly carious with exposed pulp chamber but incomplete root canal treatment. The buccal canals showing resorption were disinfected and overfilled to an extent that GP points became visible in the buccal sulcus. Raising the flap, the affected roots were cleaned and planed and the extruded GP cut and the roots resected and sealed with glass ionomer cement to encourage reattachment of periodontal apparatus. After 9-month of recall, patient is performing well with improved periodontal attachment and firmly standing tooth in the socket
ABSTRACT
This case report presents the management and follow-up of a 12-year old boy who had sustained trauma to his upper anterior teeth. The tooth 21 had an oblique fracture just above the cemento-enamel junction running from buccal to the palatal aspect of the root extending upto mid radicular area. Such fractures pose difficulty to treat them because of loosening of fractured coronal fragment. Clinicians have used various techniques to repair such fractures. In this case the coronal fracture was temporarily stabilized using orthodontic wire. Wires are used for immobilizing mandibular fractures and splinting loosened teeth. Their use for repair of fractured teeth has been described here as it is a simple procedure and wires are quite freely available in the dental clinics. This reporting will add to the already available options for saving and restoring teeth sustaining traumatic injuries. The wire was tightened circumferentially around the tooth at the cervical region. After thorough debridement and copious irrigation canal was filled. A prefabricated gold plated post was loaded with glass ionomer cement and inserted into the canal approximating the fragments close together. Subsequent to successful endodontic therapy, metal-ceramic crowns were provided as final restorations to the teeth. Clinical and radiographic examinations after 12 months revealed a perfect repair of the broken fragments with healthy peridontium

Post-operative pain and discomfort after endodontic treatment is an unwanted occasion for both the patient and the dentist. A flare up is a true complication characterized by the development of pain and swelling and requires emergency treatment. Certain factors such as pre-operative pain, numbers of appointments, use of intra-canal medication and tooth location, predispose to the development of post-operative pain and flare-ups. The purpose of this study is to analyze the incidence of post-obturation flare-ups in teeth following single visit and multiple visits Root Canal Treatment in Operative dentistry Department, Baqai Dental College, 2010 to 2011. To observe effect of: [1] skill and experience, [2] Single and multiple visits [3] Gender. Total 60 patients requiring endodontic treatment in single rooted teeth were identified and included in this study. The patients were randomly assigned and treated in the department of Operative dentistry, Baqai Dental College into two groups. The teeth of patients in group 1 were with vital inflamed pulp treated in single visit. Group 2 were with vital inflamed pulp treated in multiple visits. They were asked whether they had experienced any postoperative pain within 1 hr, within 24 hrs, within 48 hrs. Dental practitioners included in this study were fresh graduates [C1], graduates with 5 years [C2] and 10+years [C3] clinical experience. Data was analyzed statistically using the chi-square test, SPSS version 19. P-value was set at 0.001. 3 males and 5 females patients complained of pain within 24 hrs of obturation that was sharp in nature and spontaneous; no complaint of pain was reported after 24 hrs without medication. The flare-up incidence came out to be 13.3%. All patients in this study suffered irrereversible pulpitis in which 25 were obturated in single visit, 30 in multiple visits in which 5:3complained of pain after obturation within 24 hrs. Fresh graduates performed root canal therapy on 20 patients, 20 with 5+years and 20 with 10+years clinical experience and the flare-up ratio regarding clinical experience was found to be 4:3:1 respectively. It was concluded that the incidence of flare-up or post obturation pain is related to the number of visits, clinical experience of the dentist and gender of the patient
ABSTRACT
This is a case report of a lady who was worried about the presence of a small tooth like structure in the area adjacent to root treated left mandibular first molar. Intra-oral X-ray showed that it was an apically fractured part of the mesial root of the molar lodged in the buccal sulcus. The tooth was hemisected and mesial root was removed along with the dislodged part. A three unit bridge combining the hemisected root and adjacent second premolar was inserted which is successfully in service for more than a year

To assess the effect of alkaline versus acid surface treatment on bond strength of adhesives used for amalgam repair. Sixty cylindrical samples were prepared by condensing amalgam into plastic tubes 0/ 4mm diameter and 10mm length. Tubes were filled up to 5.0mm with admixed amalgam. They were allowed to set hard for three months. The samples were divided into Al, A2 andA3. Al and A2 had 25 samples each and A3 bad 10 samples. Flat exposed surfaces of the samples in Al were treated with 35% Phosphoric acid for 3 minutes. The samples in A2 were treated with 10% solution of Ca ['OH]2. A dentine adhesive containing 4-META, Amalgabond was applied on the treated surfaces. The adhesive-coated surfaces, with the help of a probe were pushed inside the tubes such that uncoated surfaces came in level with the margins of the tubes on the other end. Samples in A3 were not treated with acid or alkali and were kept as control group. Freshly mixed amalgam was packed against the coated surfaces to completely fill the transparent tubes. The samples were subjected to electromechanical testing machine at the crosshead speed of 10mm/minute to collect the data. Mean bond strength of the control samples was 3.0 MPa. It decreased with 35% phosphoric acid and increased with 10% Calcium Hydroxide in the range of 4.5 MPa. The results of the present study revealed that alkaline treatment brings more hardness to the sample surface, whereas acid softens the surface
