ABSTRACT
Infection of the dental pulp occurs as a consequence of caries, operative dental procedures and trauma. These infections often cause total pulpal necrosis and subsequently stimulate an immune response in the periapical region. The latter is commonly referred to as a periapical lesion. The ultimate goal of endodontic therapy should be to return the involved teeth to a state of health and function without surgical intervention. All inflammatory periapical lesions should be initially treated with conservative nonsurgical procedures. Surgical intervention is recommended only after nonsurgical techniques have failed. Besides, surgery has many drawbacks, which limit its use in the management of periapical lesions. A nonsurgical approach should always be adopted before resorting to surgery. Periodic follow-up examinations are essential. Irrespective of the size of the lesion every attempt should be made to treat the periapical lesions with non-surgical endodontic therapy. The aim of this paper is to present two case reports of periapical radiolucent lesions, which were treated, non-surgically.
ABSTRACT
Avulsion of tooth or teeth is defined as displacement of tooth from its socket. An avulsed permanent tooth is one of the few real emergency situations in dentistry. Avulsion of teeth occurs most often in children between 7 and 9 years of age. It requires quick emergency intervention for favourable healing followed by evaluation and possible treatment at decisive times during the healing phase. Replantation is the first line of treatment for avulsed teeth when extraoral time is less and minimal damage to the PDL. It includes stabilization of teeth in its normal position which helps in reattachment and reorganization of the periodontal ligament. Every possible effort should be made to replant it in order to avoid esthetic, masticatory, phonetic difficulties and avoid arch length discrepancy.
