| AIMS: Three cases of chronic periapical periodontitis including focal areas with malakoplakia changes are reported. methods AND RESULTS: These areas included both von Hansemann-type macrophages and periodic acid-Schiff-positive, iron- and calcium-containing concretions. Some concretions corresponded to spherules with a targetoid configuration, thus fitting the morphological criteria for classical Michaelis-Gutmann bodies. CONCLUSION: The vast majority of the cases of malakoplakia that have been reported in the literature corresponded to a characteristic, fairly homogeneous lesion, but a few instances of focal malakoplakia have been described in various chronic conditions. These considerations support the opinion that the local conditions for the production of Michaelis-Gutmann bodies may occur focally in diseases characterized by macrophage accumulation. ( info) |
2/115. An endoscopic technique for endodontic surgery. Modern endoscopy has been in existence for > 100 yr. As the desire for increased visualization in endodontic surgery continues, there is a constant search for better instruments and techniques to meet this demand. endoscopy provides the surgeon with outstanding vision and ease of use. This study refines the endoscopic technique for endodontic surgery. ( info) |
3/115. A case of an odontogenic cutaneous sinus tract. CASE REPORT: A 22-year-old female presented with a draining sinus tract on her left cheek. The tooth responsible was examined clinicopathologically. On clinical examination, the mandibular left first molar tooth was restored with an amalgam filling. Radiographic examination revealed base or pulp capping material below the restoration and a radiolucent periapical lesion surrounding the distal root apex. Conservative non-surgical root canal treatment was performed; 10 months later, the sinus had healed completely and the periapical lesion had resolved. Histopathological examination of pulp tissue recovered during treatment revealed foreign bodies, made up of capping material and amalgam, associated with chronic inflammation. These findings suggested that chronic inflammation in the pulp tissue had resulted in a draining sinus tract. ( info) |
4/115. Successful treatment of pulpal-periodontal combined lesion in a birooted maxillary lateral incisor with concomitant palato-radicular groove. A case report. Palato-radicular groove (PRG) is a common developmental anomaly of maxillary incisors, whereas PRG associated with a birooted maxillary incisor is relatively infrequent. The clinical significance of PRG is related to the incidence of localized periodontitis with or without pulpal pathosis, depending on the depth, extent, and complexity of the groove. Successful treatments of PRG in single-rooted incisors have been reported in the literature. However, treatment of PRG in birooted incisors has often been ineffective. This case report describes a pulpal-periodontal combined lesion occurring on a birooted maxillary left lateral incisor with concomitant PRG in a 13-year-old boy which was successfully treated by conventional endodontic therapy in combination with periodontal treatment including accessory root resection, radiculoplasty and bone grafting. Seven-year follow-up is included in this report. The basis of a successful result is accurate diagnosis and elimination of inflammatory irritants and contributory factors. awareness of the existence of this abnormality by the clinician is important.

5/115. Repairing iatrogenic root perforations. BACKGROUND: Post preparation is an integral part of restoring endodontically treated teeth in indicated cases. Iatrogenic perforation of the root can result from preparing post space and can severely compromise the prognosis of the tooth. CASE DESCRIPTION: Two years after a patient's maxillary lateral incisor was restored with a post-retained composite resin, he went to a dental school emergency clinic with a chief complaint of soft-tissue swelling adjacent to the tooth. The authors took a periapical radiograph that revealed evidence of a circumscribed radiolucent lesion associated with the distal midroot area and a periapical radiolucency. Based on the radiograph, the authors suspected that the canal preparation for the post and the post placement had perforated the root at the base of the post. CLINICAL IMPLICATIONS: The authors used a combined surgical and orthograde approach with a biocompatible restorative material and a clear, plastic light-transmitting post to repair the iatrogenic perforation.

6/115. Unusual case of bilateral talon cusp associated with dens invaginatus. CASE REPORT: This paper presents a rare case of bilateral talon cusp in permanent maxillary central incisors, one on the labial and another on the lingual surface of each tooth. The condition was associated with dens invaginatus in a maxillary permanent lateral incisor, but no developmental syndrome was identified. The left central incisor required no treatment because the aesthetic appearance was satisfactory and neither occlusal interferences nor caries were present. After careful investigation of the right lateral incisor, a sealant was applied. Root canal treatment was indicated for the right central incisor that had a wide open apex with thin, weak, divergent walls, and an apical radiolucency. ( info) |
7/115. Delayed apical healing after apexification treatment of non-vital immature tooth: a case report. We report the endodontic treatment of a non-vital permanent immature tooth in which unexpected complications such as exacerbation of apical periodontitis followed by external root resorption occurred after that the initial stages of the healing process were clinically and radiographically evident. After continued treatment stable repair was obtained. ( info) |
8/115. Endodontic considerations of the nasopalatine duct region. Although rare, anomalies of the nasopalatine region have been reported in the literature mimicking pathoses of endodontic origin. The purpose of this article is to present a case of a patent nasopalatine duct that was originally diagnosed as a sinus tract and referred for endodontic therapy. A review of the anatomy of the nasopalatine region is also discussed. ( info) |
9/115. Accessory branch of the mental nerve. This case report presents a surgical case in which an accessory branch of the mental nerve exited the mandible distal and slightly superior to the mental foramen. Careful manipulation of the surgical site allowed proper identification of the mental nerve, and the accessory branch and permanent nerve damage was avoided. ( info) |
| The vitality of teeth adjacent to dental implants should be considered in the treatment planning of dental implants. Both the restorability of an endodontically treated tooth and the risk of infection of the adjacent implant are important factors in planning for success. Given the illustrated difficulties and difficulties associated with resolving periapical infections of teeth and implants, it is essential to define the vitality of teeth by careful pulp testing and to consider the integrity of existing questionable, endodontically treated teeth before implant treatment. The risk of periapical infection at teeth adjacent to implants must be minimized. ( info) |
