Koirala Institute of Health Sciences, Dharan, Nepal ** Bacteriologist, Govt Medical College and Hospital, Patiala, Punjab, India INTRODUCTION Periapical pathosis is considered as an endogenous infection caused by oral microflora. Bacterial infection of dental pulp results in pulpal destruction and subsequently stimulates an inflammatory cel...

Periapical tissue from 58 cases requiring periapical surgery was examined histologically and cultured for the presence of microbes. Twenty-nine had a possible oral cavity communication and 29 did not. Approximately one-half of each biopsy was submitted for culture while the other portion was examined histologically. Cultures were positive for the presence of bacteria in 51 of 58 cases while bac...

Dental traumatic injuries may affect the teeth and alveolar bone directly or indirectly. Pulpal necrosis and chronic and apical periodontitis with cystic changes are the most common sequelae of the dental traumatic injuries, if the teeth are not treated immediately. This case report focuses on the conventional and surgical management of mandibular central incisors. A twenty-four-year-old male p...

Odontogenic infections can result from several conditions, such as pulp necrosis, periodontal disease, pericoronitis, trauma, or surgery.  The three types of odontogenic dental abscesses are endodontal periapical, periodontal, and pericoronal, depending on where the infection first developed. Periodontal abscesses, which particularly common in people with untreated disease patients during ...

A referred patient presented with a lesion of endodontic origin located at the apex of tooth #27. The tooth had been endodontically treated and re-treated. A periapical radiograph revealed a close relationship between the lesion and the maxillary sinus. A cone-beam computed tomography scan confirmed that the lesion had invaded the sinus cavity. The treatment plan consisted of periapical surgery...

Periapical lesions of endodontic origin may develop asymptomatically and become extensive. Treatment options to manage such lesions range from non-surgical root canal treatment and/or apical surgery to extraction. A high percentage of complete and partial healing of extensive perapical lesions following conventional endodontic therapy has been reported. The case reports in this article describe...

Objective: The aim of this study was to report a case of an endodontic re-treatment in a patient submitted to orthognathic surgery, using computed tomography to aid the diagnosis and treatment plan. Methods: The patient was referred for endodontic evaluation of anterior teeth with a history of orthognathic surgery on the maxilla and rigid internal fixation with miniplates for osteosynthesis in...

A case is reported of a chronic periapical lesion involving maxillary central incisors with a history of traumatic injury eight years previously and subsequent development of a painful swelling that occasionally caused partial blockage of the nasal cavities. Retrograde surgery for removal of the suspected cystic lesion was scheduled. As a temporary measure before surgery, the necrotic pulp exud...
