ABSTRACT
Background: Apicoectomy conceptualizes surgically maintaining a tooth with an endodontic lesion that cannot be resolved by conventional endodontic (re?) treatment. To achieve this, continuous improvement in surgical techniques, materials and instruments is being done to enhance the outcome of periapical endodontic surgeries. The purpose of this study was to compare, radiographically, the healing kinetics of platelet?rich fibrin (PRF) and mineralized freeze?dried bone allograft (FDBA) in patients undergoing apicoectomy. Materials and Methods: Nineteen patients (aged 18–40 years) were included in the study and randomly assigned to groups A or B, where they received PRF or FDBA, respectively. Following apicoectomy, PRF gel and FDBA graft were prepared and placed in the osseous defect followed by placement of PRF membrane for graft stabilization and flap closure. Radiographic follow?up was done at the 1st, 3rd, 6th and 12th months for evaluation of healing using Molven’s criteria. Statistical analysis was done with Pearson’s and McNemar’s Chi?square tests. Results: A highly significant difference (P = 0.002) in radiographic healing was observed at 6 months. Complete healing was observed in 50% of cases in Group A whereas in Group B, none of the cases presented with complete radiographic healing. However, at the end of 12 months, complete radiographic healing was observed in both groups. Conclusion: Our data suggest that PRF accelerates bone healing as compared to FDBA and is both time and cost?efficient.
ABSTRACT
A patent urachus is one of the spectrums of congenital urachal anomalies. It has been termed as "urachal fistula" when the lumen of intra-embryonic portion of allantois persist abnormally. Persisting urachal fistula is a rare condition mostly diagnosed during childhood or in autopsies. Here we report a very rare case of urachal fistula of a young male. We present a case of 22 years male with intermittent periumbilical pain and sero-purulent discharge from umbilicus since birth. On examination sero-purulent discharging umbilical sinus with granuloma was present. Surgical excision of whole of the urachal fistulous tract was done with repair of bladder. Patient did well during post-operative period. Persisting urachal fistula in adult is rare entity and difficult to diagnose because of low incidence and non-specific symptoms. So a high index of suspicion is required in order to make the early diagnosis of urachal anomalies.
ABSTRACT
LASER (Light Amplification by Stimulated Emission of Radiation) is a powerful source of light, which has innumerable applications in all the fields of science including medicine and dentistry. It is one such technology that has become a desirable and an inseparable alternative to many traditional surgical procedures being held in the field of dentistry, and orthodontics is no exception. The current article describes the uses of a diode laser as an indispensable tool in an orthodontic office.
