this paper reports multidisciplinary treatment of a dental trauma case to achieve a favorable prognosis. a healthy 14-year-old girl reported avulsion of teeth 11 and 21 which had occurred three months earlier. the initial treatment consisting of replantation with a semi-rigid splint was performed in hospital. at presentation, the patient was still using the semi-rigid splint. the clinical exami...

survivorship of the immature stage of anopheles culicifacies in damar district were studied through sampling larval and pupal stages from stream bed pools and rice fields during may and august 1993. the duration of each larval instar and the pupal stage was also determined in the laboratory for preparing the survivorship curves and the construction of the life tables. mortality from egg to adul...

Objective: This study aimed to evaluate the effect of bleaching discolored teeth after regenerative endodontic treatment on fracture resistance. Methods: Forty human maxillary incisors were selected for and divided into four groups (n=10). Group 1 was called positive control group, no applied. In 2; root canals enlarged size 6 peezo reamer bur mimic an immature tooth. The disinfection protocol ...

Introduction: The endodontic management of necrotic permanent immature teeth is a challenge for the practitioner. These are treated by apexification. However, because complications associated with this treatment, researchers have developed other therapies. Currently, new technique called pulp revascularization has emerged. This allows continuation root completion thanks to healthy tissue newly ...

The purpose of the present study was to investigate whether fluoride (F) ions are really capable of the repair (remineralization) of damaged crystals and useful for reinforcing the quality (i.e. modify the crystal structure) of tooth enamel using transmission electron microscopy and Raman microprobe analysis. Additionally, carbonic anhydrase activity was measured in immature enamel tissue to co...

Introduction: Complicated crown fractures involve enamel, dentin, and pulp and occur in 0.9 to l3% of all dental injuries. If left untreated, will always result in pulp necrosis but, if it handled correctly, prognosis of the pulp following a traumatic crown fracture can be favorable. Case Report: The present case report describes an apexogenesis report of a 9-year old boy referred to department...

fusion is a developmental anomaly defined as the :union: of two normally separated tooth buds or the partial splitting of one tooth bud into two buds. depending on the stage of development, fusion may be either complete or incomplete. the significance of this particular case was that this fusion occurred in a posterior permanent mandibular tooth, while such a manifestation is more reported in m...

Traumatized tooth rendered nonvital (pulpal necrosis) before the final stage of the root development results in a short root with a wide canal that can be either divergent or parallel. Although the root canal therapy is the choice of treatment for a nonvital tooth, the above mentioned abnormal root anatomy does not permit a predictable outcome. Mainly, it is not feasible to achieve a good apica...
