RESUMO
Endodontic microsurgery in tandem with advanced radiographic techniques has led to the emergence of guided surgeries. Preservation of the cortical bone to enhance the healing and stabilization of tissues surrounding the tooth of concern can now be facilitated by bone cement used in the field of orthopedics. This case report details a guided endodontic surgery technique in 17 years old where a traumatic infliction leads to a phoenix abscess. The technique elaborated emphasizes on the three-dimensional printing of a surgical template with the help of cone-beam computed tomography, followed using a medical-grade bone cement in the most minimal manner to reposition the buccal cortical bone. A 12-month-old follow-up revealed the patient to be asymptomatic with a flawless periapical region radiographically. This case testifies that the optimum use of available biomedical material in surgical endodontics can assure a predictable prognosis.
RESUMO
Pulse oximetry is an equipment that evaluates pulp vitality for concrete endodontic diagnosis and treatment plan. One of the treatment methods of oropharyngeal cancer is radiotherapy. Radiotherapy has some harmful effects on dental pulp that affects pulp vitality. The objective of study was to assess pulp vitality before, at the end of radiotherapy and six months after radiotherapy (RT) in oropharyngeal cancer patients undergoing radiotherapy. 25 patients who were diagnosed with oropharyngeal cancer having asymptomatic intact crowns were selected for the study. Pulp vitality was checked before the commencement of radiotherapy (PV1), immediately after radiotherapy (PV 2) and six months post radiotherapy (PV 3). Pulp vitality of first posterior tooth was selected of each patient and was checked with pulse oximetry. Paired t-test was used as statistical analysis. Statistically significant difference was observed when PV 1 and PV 2, PV 1 and PV 3 and PV 2 and PV 3 were compared amongst each other. There was reduction noted in mean SpO2 value when groups PV 2 and PV1 were compared. This was statistically significant. Statistically significant increase in mean SpO2 value was observed six months post radiotherapy (PV 3). Thus, it can be concluded that statistically significant reduction in mean SpO2 level post radiotherapy recovers after six months.
RESUMO
The aim of this study was to recognize the importance of canalis sinuosus in Endodontics. A 60-year-old male patient reported with the chief complaint of pain and swelling in upper front tooth region for 2 weeks with a history of trauma 21 years back. Clinical examination revealed fractured tooth 21 (maxillary left central incisor) with an associated sinus tract. Radiographic examination revealed diffuse periapical radiolucency in relation to tooth 21 and external resorptive defect in apical third of the root of tooth 11 (maxillary right central incisor). Cone-beam computed tomography advised to plan surgical treatment for the same disclosed the presence of an anatomic variation of canalis sinuosus. The location and course of this canal illuded as a resorptive defect, which is a very rare occurrence. This led to a change in diagnosis with relation to tooth 11 and treatment plan was formulated accordingly.
