The purpose of this study was to evaluate the effects of aminoguanidine (AG) as a selective inhibitor of inducible nitric oxide synthase (iNOS) on the degree of inflammatory response in periapical lesions in the canine teeth of cats. Root canals from 52 cat canine teeth were exposed to the oral cavity and sealed after 7 days. One day before pulp exposure, cats were administered either AG (exper...

Many studies have been reported on radiographic lesion sizes of periapical lesions. However no studies have been reported on prevalences of subjective radiographic features in these lesions except for the early assumption that a periapical cyst usually exhibit a radiopaque cortex. This study is conducted to evaluate the prevalences of several subjective radiographic features of periapical cysts...

background and aims. accurate differential diagnosis between radicular cysts and periapical granulomas cannot be made from radiographs alone. histological prevalence studies, therefore, assume special importance and may aid the clinician in making judgments regarding therapy. the incidence of radicular cysts has ranged with wide discrepancies in data. the purpose of this study was to evaluate r...

Calcium hydroxide is used extensively as an intracanal medicament in endodontics for many years. It is used in various clinical situations such as to promote apexification, to repair perforation, to enhance healing of periapical lesions, to control root resorption, and to control exudation in teeth with persistent periapical inflammation. This paper presents a case report in which Ca(OH)2 was u...

Endodontic surgery aims at the resolution of a periapical inflammatory process by surgical access followed by enucleation of the lesion and root-end filling to curb any potentially noxious agent within the physical confines of the affected root. Guided bone regeneration could be associated to endodontic surgery aiming to enhance periradicular tissue regeneration. The objective of this paper was...

The case reports describes non surgical healing in periradicular lesions.A conservative approach with 5.25% sodium hypochlorite was used for irrigation, and calcium hydroxide was used for the intra-canal dressing and 2% chlorohexidine as a final irrigant. Periapical healing was observed 1 month after obturation and continued in the 12-month recall. This report confirms that the large size of a ...

D entists are repeatedly confronted with the problem of diagnosing and treating periapical lesions. Ordinarily, a nonsurgical cndodontic approach is used in treating lesions that are thnnght to be periapicul granulomas, whereas surgical therapy often is used if the lesion is believed to bc cyst,ic. Thus, choice of treatment usually depends on the clinical assessment of the lesion. Accurate difl...
