When the caries become near the pulp in primary molars, the treatment will be the pulpotomy to remove the involved coronal portion of the pulp, preserving the vitality and function of the remaining radicular portion. Formocresol, Glutar-aldehyde, F erric sulphate, AMT, Laser application and Electro surgery may used in primary teeth pulpotomy.
The purpose of this study was to evaluate the success of Formocresol pulpotomy compared with Ferric sulfate and Electro coagulation and Laser pulpotomy in primary teeth. Fourty seven primary second molars of children aged 5-8 years, were divided r andomly into four groups: 10 Formocresol , 13 Ferric sulfate , 13 Electro coagulation, 10 Laser. All teeth were filled with ZOE and sealed with Compomer, and S.S.Crown as final restoration. The success rate was 90 % - 84.6 % - 84.6 % - 83.3 % respectively. These differences were not statistically significant p=0.05), but there were a relation between the pretreatment physiologic resorption of roots and the type of hemorrhage during the amputation procedure. This study revealed that Ferric sulfate, and Electro coagulation, and Laser pulpotomy are good alternative to Formocresol pulpotomy.
Fear of a painful dental injection specially in children is significant barrier to regular visits to the dentist, so the aim of this study was to assess the efficacy of primary maxillary second molars anesthesia using lidocaine 10% nasal spray during restorative cavity preparation.
Few researchers have made a comprehensive study of the morphology of the root canals of the primary molars. Thorough knowledge in internal anatomy of the primary molars is useful in reducing the problems of endodontic therapy arising due to the ana tomical variation in root canals, which are clinically difficult to be detected. Exploration the root canals of primary molars with regard to its number, variations, and accessory canals in the furcation region. the complication of the internal anatomy of primary molars causing complication in endodontic treatment so the results of this study suggest avoiding pulpectomy in primary molars where ever possible.
