Wound healing responses of the tissues of the periodontium following periradicular surgery in rhesus monkeys were evaluated by light microscopy. Part II of this investigation reports the responses of mucoperiosteal and osseous tissues to blunt dissectional wounding resulting from the reflection of triangular or submarginal rectangular flaps. Healing of the dissectional wound is rapid, although ...

This study intended to examine histologically root canal-treated teeth evincing apical periodontitis lesions and correlate the findings with clinical observations. Specimens were obtained from 24 patients (12 asymptomatic and 12 symptomatic) by extraction or endodontic surgery and consisted of roots or root tips and the associated pathologic lesion. Specimens were processed for histologic analy...

AIM This randomized, controlled, clinical study was designed to evaluate the adjunctive effect of calcium sulphate grafts on the surgical treatment of through and through periradicular lesions. METHODOLOGY Twenty patients each with one tooth showing evidence radiologically of a periradicular lesion wider than 10 mm, with lack of both buccal and lingual cortical bony plates and an indication f...

AIM To analyse the healing response to gutta-percha and Diaket when used as root-end filling materials in periradicular surgery. METHODOLOGY Periradicular surgery was completed using the mandibular second, third and fourth premolar teeth from nine male mongrel dogs. The six roots on one side of the mouth were randomly allocated to one of the following groups: group A: a resected root end and ...

severe traumatic injuries to immature teeth often cause damage to periodontal ligament as well as dental pulp; pulp necrosis, root resorption and subsequent apical lesion are common consequences. this article reports the surgical management of an infected immature maxillary central incisor associated with a gigantic periradicular lesion and severe root resorption. the tooth had a history of tra...

The cyst in mixed dentition stage cause expansion of buccal cortex, displacement of teeth and may present as case of infection. The cyst in periradicular region of deciduous molar are of frequent occurrence. The differential diagnosis of this lesion is radicular cysts of deciduous molar: developmental or infammatory dentigerous cyst of corresponding unerupted premolar. After going through the a...

The purpose of this article was to illustrate an alternative approach to non-surgical management of teeth with failed surgical retreatment. The patient presented with complaint of severe pain after endodontic treatment of the maxillary right lateral and central incisors, which has not been reduce by periradicular surgery. Radiographic examination revealed the poor quality of both the endodontic...

reatment of molar radicular cysts is challenging and many olars may be removed if endodontic treatment is unsucessful. Conventional periradicular surgery of molars is not lways done, because of the technical difficulties and poor isualisation. Endoscopic periradicular surgery (EPS) has een introduced to avoid having to remove molars.1–3 If lling of the root canal is insufficient, we use EPS aft...

AIM The aim of this study is to determine the presence and distribution of Langerhans cells in periapical lesions, and correlate this with inflammatory cell infiltration and epithelial cell proliferation. MATERIAL AND METHODS Seventy chronic dental periradicular lesions, obtained during periapical surgery from 70 patients, were included in this study, including: 46 granulomas, 18 scar tissue ...

AIM A species-specific nested polymerase chain reaction (PCR) assay was used to investigate the occurrence of Campylobacter gracilis and C. rectus in primary root canal infections. METHODOLOGY Samples were collected from 57 single-rooted teeth with carious lesions, necrotic pulps and radiographic evidence of periradicular disease. Twenty-eight cases were diagnosed as chronic asymptomatic peri...
