1/24. Delayed eruption of premolars with periodontitis of primary predecessors and a cystic lesion: a case report.

    Apical periodontitis after pulp therapy in a primary tooth can cause delayed eruption of the permanent successor. A case of bilateral delayed eruption of mandibular premolars is presented. The patient. a 13-year-old girl, was referred by her dentist. Oral findings showed that the right first and left second primary molars were retained. Other premolars had erupted. An orthopantomogram revealed apical periodontitis, affecting both retained primary molars. The right first mandibular premolar was impacted against the alveolar bone and root of the second premolar, and there was a large cystic lesion in close association with the left second mandibular premolar. Both primary molars were extracted, and the cystic lesion was treated by marsupialization. Fenestration and traction were performed on the right first premolar. Correct tooth alignment was achieved with orthodontic appliances. If the problem had been detected earlier, treatment of the premolars might have been easier. Clinical and radiological follow-up, therefore, of primary teeth that have undergone pulp therapy procedures should be performed until eruption of succedaneous teeth.

2/24. Case report: a large radicular cyst involving the entire maxillary sinus.

    cysts of the maxillary sinus of odontogenic origin have been well-documented in the literature. Most of these lesions involve the apex of the offending tooth and appear as a well-defined periapical radiolucency. Presented here is a case of an unusually large lesion, which involved the entire maxillary sinus and extended into the floor of the nose. The lesion also caused paresthesia on the affected side. The lesion was removed with conservative treatment without any postoperative complications.

3/24. Paradental cyst mimicking a radicular cyst on the adjacent tooth: case report and review of terminology.

    A distinctive form of paradental cyst can occur on the buccal and apical aspects of erupted mandibular molars. This cyst has peculiar clinical and radiographic features, although the microscopic findings are the same as those of odontogenic inflammatory cysts. Diagnostic and therapeutic problems can occur when this lesion is misinterpreted as a radicular cyst. The purpose of this paper is to present an additional case of a paradental cyst in the buccal and mesial aspects of a mandibular second molar involving the apical area of a mandibular first molar. The difficulty of diagnosis, treatment, and controversies regarding terminology are also discussed.

4/24. plasmacytoma of anterior maxilla mimicking periapical cyst.

    An unusual case of plasmacytoma mimicking a large periapical cyst in the anterior maxilla is described. Of the involved teeth, 22 was discoloured and had an open, immature apex, a feature strongly suggestive of the lesion being of pulpal origin. The case was treated by a conservative endodontic approach, but failed to show any improvement. Apical surgery comprising complete enucleation of the cystic lesion and extraction of the involved tooth was carried out. The unexpected histopathological finding was a plasmacytoma.

5/24. radicular cyst associated with endodontically treated deciduous tooth: a case report.

    This article presents a case report of radicular cyst associated with an endodontically treated deciduous second molar causing displacement of the permanent successor, with accompanying buccal expansion. Cystic sac was removed surgically along with the involved tooth under general anesthesia. Healing was uneventful. Histopathologically the cystic sac was consistent with the features of radicular cyst. Unusual amorphous, eosinophilic, atubular material incorporated within the cystic epithelium was observed.

6/24. infection-related inferior alveolar and mental nerve paresthesia: case reports.

    Nerve injury can be related to mechanical, chemical, and thermal factors. infection-related paresthesia is usually related to mechanical pressure and ischemia associated with the inflammatory process. Another cause of paresthesia could be the toxic metabolic products of bacteria or inflammatory products released following tissue damage. This article presents cases of inferior alveolar and mental nerve paresthesia caused by an infected impacted tooth, an infected cyst, and periapical infection. The possible pathophysiologic mechanism of nerve injury, therapy, and prognosis for recovery are also discussed.

7/24. Combined endodontic and surgical treatment of a three-rooted maxillary first premolar.

    A case is reported in which endodontic treatment of a maxillary first premolar was complicated by the fact that the tooth had three roots. One of the roots was completely calcified and therefore could not be negotiated with endodontic files. There was a large periapical lesion associated with the tooth and this was surgically removed. During the surgical procedure a retrograde cavity was prepared on the calcified root using ultrasonic instruments and this was filled using Super EBA cement. Twelve months later the tooth was asymptomatic and the periapical tissues had completely healed.

8/24. Endodontic management of dens evaginatus of maxillary central incisors: a rare case report.

    Dens evaginatus is a disturbance in tooth development that produces a tubercle of hard tissue on the surface of the tooth. While prophylactic pulp capping is recommended for vital teeth, teeth with necrotic pulps require endodontic therapy or extraction. This rare case of a 24-yr-old Indian male with affected maxillary central incisors demonstrates the clinical consequences of dens evaginatus.

9/24. Unicystic ameloblastoma: a possible pitfall in periapical diagnosis.

    AIM: To report a clinical case of unicystic ameloblastoma previously misdiagnosed as radicular cyst. SUMMARY: A 49-year-old white male was referred to a private practitioner complaining of an asymptomatic bony hard swelling of the left posterior mandible. The patient's dental history indicated that his left mandibular first molar had been extracted approximately 10 years previously. At that time, preoperative radiographic examination demonstrated a radiolucent area of 1.5 cm diameter with well-defined margins involving the distal root of tooth 36. The lesion was diagnosed as cystic and surgery for its removal was advised, but not performed. At presentation, radiography demonstrated a well-defined 3 cm diameter radiolucency extending from the second premolar to the second molar. The lesion was enucleated and histopathological examination confirmed a diagnosis of unicystic ameloblastoma. KEY learning POINTS: *Despite a clinical diagnosis of periapical disease of endodontic origin, a nonendodontic lesion may be present. *Unicystic ameloblastoma located on the periapical area of a tooth can lead to a pulp-periapical misdiagnosis, and should be considered in differential diagnosis. *All tissue specimens recovered in apical surgery should be submitted to histopathological analysis.

10/24. Complications following replantation of a primary incisor: a cautionary tale.

    The replantation of avulsed primary incisors is contra-indicated. This case describes an 8-year-old child who six years previously had avulsed and had replanted a primary central incisor. At presentation, this tooth was retained, the permanent successor had failed to erupt and appearance of the adjacent lateral incisor was notably delayed. Investigation revealed a radicular cyst in relation to the replanted deciduous incisor together with severe displacement of the permanent tooth, which could not be saved.
