Traumatic injuries commonly affect the anterior teeth leading to slow death of the pulp. This may give rise to a periapical or radicular cyst which results from the proliferation of cell rests of Malassez following pulpal necrosis of a nonvital tooth. This condition is usually asymptomatic but can result in a slow-growth tumefaction in the affected region. On radiography the lesion can be seen ...

In teeth with periapical lesions and defective root canal seals non-surgical retreatment is usually preferred. Sometimes, however, such treatment may not be feasible and periapical surgery must be performed. The present study investigated a technique of retrograde root canal treatment as an alternative to the more conventional types of surgical procedure. The material consisted of 35 teeth whos...

This paper describes and discusses the multidisciplinary treatment involving a permanent maxillary lateral incisor fused to a supernumerary tooth, both presenting pulp necrosis and periapical lesion. A 15-year-old male patient sought treatment complaining of pain, swelling and mobility on the maxillary right lateral incisor. After clinical and radiographic examination, root canal preparation wa...

OBJECTIVE To explore the relationship between cone beam computed tomography (CBCT) measurements and direct measurements during the surgery to correct intrabony defects. METHODS Forty-four patients with 44 intrabony defects who finished initial periodontal therapy and were considered for periodontal surgery were recruited. Digital periapical radiography and CBCT was performed before the surger...

Conventional nonsurgical endodontic treatment has a high degree of clinical success, but in certain cases surgical intervention becomes necessary. This is the case report of a patient presenting with bilaterally separate periapical lesions in the maxillary anterior region. One lesion was managed by periapical surgery using a novel and safe method of separating the soft tissue mass of the periap...

The new Apexum procedure (Apexum Ltd, Or-Yehuda, Israel) is based on a minimally invasive removal of periapical chronically inflamed tissues through a root canal access. Apexum procedure (a novel method that allows for the removal or debulking of periapical tissues without using scalpels, periosteal elevators, or sutures) results in significant less postoperative discomfort or pain than convent...

Large periapical defects may adversely affect the success rate of endodontic surgery. Use of regenerative therapy may enhance the prognosis of such teeth. A case of traumatized upper anterior teeth with infected radicular cyst and associated sinus tract reported to the dental hospital. A periradicular surgical procedure was performed to remove the nonhealing pathological tissue. To augment the ...

Background: Pulp necrosis is a common detrimental consequence of dental traumatic injuries. Early management of such cases is mandatory in order to prevent subsequent pathological changes that could further complicate the treatment. Pulp necrosis, chronic and cystic apical periodontitis can be the fate if these teeth are left untreated. Despite these serious complications, root canal treatment ...
