1/36. 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.- - - - - - - - - - ranking = 1keywords = periodontitis, alveolar (Clic here for more details about this article) |
2/36. 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.- - - - - - - - - - ranking = 32.198936623485keywords = periapical (Clic here for more details about this article) |
3/36. Adenomatoid odontogenic tumor mimicking a periapical (radicular) cyst: a case report.The adenomatoid odontogenic tumor (AOT) is a benign (hamartomatous), noninvasive lesion with slow but progressive growth. A rare subvariant of the extrafollicular type of AOT may mimic periapical disease radiographically. We report on a 15-year-old girl with a periapical radiolucent lesion affecting teeth 7 and 8 initially suspicious of periapical disease, although clinical findings seemed to indicate a nonendodontic lesion. An exploratory surgical approach was chosen, and the final diagnosis of the removed noncystic tissue mass was microscopically confirmed to be an AOT.- - - - - - - - - - ranking = 225.39255636439keywords = periapical (Clic here for more details about this article) |
4/36. The treatment options of dens invaginatus complications in children: report of 3 cases.PURPOSE: The authors described 3 cases of dens invaginatus accompanied by different periapical complications in children, as well as the therapy methods they used. methods: The 3 children were between the ages of 12 and 16 years. The type of dens invaginatus was classified according to Schulze and Brand. RESULTS: All 3 cases had dens invaginatus on their permanent teeth in the maxilla. The complications occurred while the teeth were growing, and they were accompanied by swelling in the region of the dens invaginatus. CONCLUSIONS: The periapical complications required early diagnostic and endodontic treatment to prevent further difficulties at a later stage.- - - - - - - - - - ranking = 64.397873246969keywords = periapical (Clic here for more details about this article) |
5/36. 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.- - - - - - - - - - ranking = 160.99468311742keywords = periapical (Clic here for more details about this article) |
6/36. Periapical radiolucency mimicking an odontogenic cyst.AIM: To present a clinical case of a giant cell lesion located in an unusual site, initially misdiagnosed and treated as an odontogenic cyst. SUMMARY: Periapical radiolucencies often suggest the presence of odontogenic pathosis, usually inflammatory granulomas or cysts. The high frequency of such lesions tends to lead clinicians to arrive at a diagnosis without completing a comprehensive assessment of the patient or carrying out the full range of available diagnostic tests. A case report of a giant cell lesion, which was misdiagnosed and treated initially as an odontogenic lesion because of its unusual location, is presented. KEY learning POINTS: Clinical signs and radiographic appearance are usually sufficient to reach a diagnosis of periapical pathosis. When traditional treatment does not lead to success, a biopsy should be considered to ascertain the diagnosis and allow the correct treatment to be provided. Histological examination of soft tissue removed during endodontic surgery is essential.- - - - - - - - - - ranking = 32.198936623485keywords = periapical (Clic here for more details about this article) |

8/36. 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.- - - - - - - - - - ranking = 32.202043307424keywords = periapical, alveolar (Clic here for more details about this article) |
9/36. 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.- - - - - - - - - - ranking = 64.397873246969keywords = periapical (Clic here for more details about this article) |
10/36. 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.- - - - - - - - - - ranking = 225.39255636439keywords = periapical (Clic here for more details about this article) |
