1/3. Cutaneous draining sinus tract of odontogenic origin: unusual presentation of a challenging diagnosis.A 44-year-old woman presented with a chronically draining lesion on her cheek just lateral to the nasofacial sulcus. The lesion was refractory to treatment with oral antibiotics. physical examination revealed poor dentition, and a panoramic radiograph demonstrated periapical abscesses in the maxillary right lateral incisor and canine. A diagnosis of cutaneous fistula of odontogenic origin was made, and the patient was treated with tooth extraction. The cutaneous fistula subsequently resolved. Intraoral examinations and radiographs are critical for making the diagnosis of cutaneous draining sinus tract of odontogenic origin. Many patients undergo unnecessary surgical therapies before having the correct diagnosis made, but root canal therapy or surgical extraction is the treatment of choice. A dental origin must be considered for any chronically draining sinus of the face or neck.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/3. Histological observations of periradicular healing following root canal treatment.The purpose of this study was to observe histologically the sequence of events leading to resolution of periradicular tissues, with a view to advancing the perception of periapical healing. Our material consisted of periapical specimens obtained from 15 single-rooted, endodontically treated teeth of patients aged 25-40 years. All the teeth required extraction because of complicated crown-root fracture following trauma, iatrogenic aetiology (cervical root resorption following bleaching) or extensive carious lesions. The patients were informed that, based on their clinical condition, surgical procedures should be performed under flap reflection in order to extract the fractured root. informed consent, which was necessary for the surgery, was obtained in all cases. A small block section containing the apical root tip and surrounding periapical tissues was removed prior to root extraction. The results of histological examination revealed osteoblastic activty and osteoid bone formation six days after the root canal instrumentation. periapical tissue healing was observed despite the presence of overfilled material. The lining epithelium was infiltrated with chronic inflammatory cells and surrounded by collagen bundles and newly formed bone.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/3. The buccal bifurcation cyst: in non-surgical treatment an option?The mandibular buccal bifurcation cyst (BBC) was first described by Stoneman and Worth in 1983. It is a lesion with a specific location, classically the buccal surface of the mandibular first molar and less frequently the mandibular second molar. There have been numerous reports in the literature describing the BBC and its treatment. Treatment advocated thus far includes extraction of the involved first molar, marsupialization and enucleation of the cyst. In their most recent article, Pompura, Sandor and Stoneman reported on the successful treatment of 44 cysts with enucleation without tooth extraction. This article will describe the diagnostic features of the BBC and present three cases with a total of five cysts, which were treated non-surgically and ultimately resolved. The authors, therefore, propose that a more conservative non-surgical approach to these lesions may be considered.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
