This article presents non-surgical resolution of an extensive periapical lesion of endodontic origin associated with the maxillary left lateral incisor. Clinical examination revealed an asymptomatic bony hard swelling confined to the palate, while radiographic analysis showed a lesion measuring 22 mm in diameter and nearly 389 mm(2) in area. Through apical patency, 4 ml of intracanal exudate wa...

The implant periapical lesion is the infectious-inflammatory process of the tissues surrounding the implant apex. It may be caused by different factors: contamination of the implant surface, overheating of bone during drilling, preparation of a longer implant bed than the implant itself, and pre-existing bone disease. Diagnosis is achieved by studying the presence of symptoms and signs such us ...

AIM To test the ability of periapical radiography (PA) and cone-beam computed tomography (CBCT) to determine the presence/absence of periapical lesions and examine the reliability of volumetric measurements of periapical lesions on CBCT scans. METHODOLOGY After tooth extractions in human mandibles, bone defects were cut at the base of extraction sockets to mimic periapical bone lesions. The t...

Periapical diseases are induced as a result of the direct or indirect involvement of oral bacteria. The etiologic factor being the degenerating pulp tissue. A periapical lesion is formed within an area of apical periodontitis which cannot form by itself and is inflammatory in origin. If the microbial etiology of periapical lesions and in the root canal is removed by nonsurgical root canal thera...

b a u c g picoectomy involves the surgical management of tooth with a periapical lesion which cannot be esolved by conventional endodontic treatment root canal therapy or endodontic retreatment). ecause the term “apicoectomy” consists of only ne aspect (removal of root apex) of a complex eries of surgical procedures, the terms “periapical urgery” or “periradicular surgery” are more approriate. ...

Implant periapical lesions are infectious-inflammatory alterations surrounding an implant apex, and can be caused by a number of situations--including contamination at instrumentation, overheating of bone, and the prior existence of bone pathology. The diagnosis is based on the clinical manifestations and radiological findings, where a radiotransparency can be seen at periapical level. The lesi...

Periapical disease caused by the colonization of microrganisms in the root canal system. Microbiology implicated in endodontic disease is diverse and varied. Mircobial testing of periapical lesions can be traced back to 1890. The changes in balance of the microbiota along with other factors host resistance and viral infection can also affect the periapical disease. The various microbiology invo...

This article reports non-surgical endodontic retreatment of two patients with persistent or recurrent periapical lesions, who had previously undergone surgical and non-surgical endodontic therapy respectively. It further discusses and reviews the relevance of classification of periapical lesions, the explanation behind healing of periapical lesions by endodontic therapy alone, causes of persist...

The purpose of the study was to histologically analyse transition from pulpitis to periapical periodontitis on dog's teeth. Pulps of mandibular premolars (37 roots) were exposed using a low-speed handpiece. Teeth were left open to the oral environment for 20, 35, 50 and 65 days. After the experimental period animals were sacrificed. Undemineralised teeth with surrounding bone, embedded in methy...

During the past few decades several authors have perpetuated the notion that nearly half of all periapical lesions are radicular cysts. A few studies, based on meticulous serial sectioning of periapical lesions retrieved in toto, have shown that the actual incidence of radicular cyst is only about 15% of all periapical lesions. Equally significant was the discovery in 1980 and recent confirmati...
