successful treatment of a large implant periapical lesion (ipl) that caused paraesthesia and perimandibular abscess. ipl is a pathologic phenomenon that rarely involves implants. this event first described in 1992 with an incidence rate of 0.26–9.9% and the origin is not well known. the most likely suggested causes are presence of preexisting bone pathology, contamination of implant surface, bo...

introduction: bacterial infection of tooth pulp can progress into periapical diseases. root canal treatment has been established as the best treatment. in cases of failure, nonsurgical retreatment of teeth is preferred to surgical procedure and extraction. materials & methods: in this historical cohort study, 104 permanent teeth with apical lesion were treated during 2002-2008. all teeth showed...

paresthesia is a burning or prickling sensation or partial numbness, resulting from neural injury. the symptoms can vary from mild neurosensory dysfunction to total loss of sensation in the innervated area. only a few cases have described apical periodontitis to be the etiological factor of impaired sensation in the area innervated by the inferior alveolar and mental nerves. the aim of the pres...

In the oral cavity, extranodal non-Hodgkin's lymphoma can occur in the periapical region either in the maxilla or mandible. Also, it can mimic inflammatory lesions that arise around the teeth apices such as periapical granuloma, radicular cyst and osteomyelitis. Misdiagnosis of lymphomas in the jaws may reduce the chance of successful treatment and worsen the prognosis. Therefore, any growth of...

AIM To report a case of conservative nonsurgical management of periapical lesions. BACKGROUND Small periapical lesions of endodontic origin usually heal by conventional endodontic therapy alone. Larger periapical lesions presumed to be cystic may require additional treatment protocols to aid in regression. Conservative nonsurgical management of such lesions eliminates the possible complicatio...

AIM To present an additional case of intraosseous schwannoma involving the apical area in the mandibular alveolar bone mimicking an inflammatory periapical lesion. SUMMARY This article describes a case of schwannoma periapically located mimicking an inflammatory periapical lesion in the mandible of a 34-year-old female. Diagnostic and therapeutic problems can occur when this lesion is misinte...

Case Description: This tumour appeared in the anterior region of the left upper jaw of a 24year-old female, between left lateral incisor and canine. The lesion was painless and only a slight swelling of the hard palate mucosa was noted. Radiographically, a well-delimited peaklike radiolucent area promoting root divergence was observed. The lateral incisor failed in responding positively to the ...

The aim of this study was to quantify radiographically the periapical bone resorption in dogs' teeth contaminated with bacterial endotoxin (LPS), associated or not with calcium hydroxide. After pulp tissue removal, 60 premolars were randomly assigned to 4 groups and were either filled with LPS (group 1), filled with LPS plus calcium hydroxide (group 2) or filled with saline (group 3) for a peri...
