Platelet Rich Fibrin in Management of Complex Endoperio Cases.

Endo-perio lesions have been a dilemma to the dental practitioner. Both tissues share the same anatomical origin. Sometimes exact etiological passage of disease process cannot be traced; nevertheless traditional and newer treatment modalities must be employed to ensure best treatment possibilities. Patient reported with pain and pus exudates in upper left anterior region. Past dental history revealed no history of trauma. Initial examination revealed draining sinus with respect to 22. However, no Caries and pockets could be detected. Tooth was nonresponsive to vitality test. Patient symptoms did not relieve even two months after completion of RCT. Apical surgery was planned. Apicectomy was done and osseous defect was filled with PRF coagulum. Patient was followed up every three months and showed complete resolution of all symptoms. Radiographs showed complete resolution of osseous defect in nine months. PRF can be used to enhance bone augmentation in treatment of periapical defects as a potential treatment alternative for faster healing.

Dental exarticulation.

Tooth exarticulation or avulsion refers to the complete displacement of the tooth out of its socket. It is a complex injury, requiring immediate intervention for optimal results. Literature indicates that prolonged dry time and improper handling may be associated with increased risk of failure. Immediate replantation of the tooth allows for immediate restoration of esthetics and phonetics. This case report presents the management of an avulsed mature tooth in a young boy, with a two-year follow-up, which had been preserved in milk after around 15-20 minutes of injury and transplanted after two hours at a dental hospital. Timely modified endodontic therapy prevented subsequent inflammatory root resorption.

Chronic cutaneous draining sinus of dental origin.

Extra oral sinus of odontogenic origin occurs when the purulent by-products of dental pulp necrosis spread along the path of least resistance from the root apex to the skin on the face. Patients presenting with cutaneous sinus usually visit a general physician or dermatologist first, as the lesion can mimic various dermatologic pathologies, ranging from an infected sebaceous cysts to a basal cell carcinoma. Despite systemic antibiotics, symptoms often persist causing further confusion, and at times leading to unnecessary surgical interventions. The location of this sinus in the head and neck region should lead the physician to seek a dental opinion in order to avoid misdiagnosis.
