BACKGROUND: Adenomatoid odontogenic tumors (AOT) and calcifying odontogenic cysts (COC, Gorlin's cyst) are rare benign specificities of odontogenic tumors. Most odontogenic tumors are lesions of embryonic odontogenic tissue. Radiographically, odontogenic tumors may mimic an odontogenic follicular cyst. CASE REPORT: This paper describes the case of an 11-year-old female patient with a remarkable combination of these two entities. The lesions were found at the site of a retained first premolar and a persistent deciduous tooth 84 of the right lower jaw. Without clinical symptoms the tumor had expanded the vestibular cortical bone of the premolar region. Radiographically, the lesion appeared as a typical follicular cyst. During the operation, excochleation of the cyst was performed and the premolar was extracted. Finally, the epithelium of the cyst was treated by curettage. The histologic specimen revealed the diagnosis of an adenomatoid odontogenic tumor (AOT) in a calcifying odontogenic cyst (COC). DISCUSSION: The described case shows that symptoms of odontogenic tumors are usually nonspecific. For that reason one should always take a biopsy for histological investigation when patients present atypical cysts of the jaw. In rare cases even malignant odontogenic neoplasms could occur.
Ekman-Westborg and Julin [1974: Oral Surg 38:217-222], described multiple macrodontia and multituberculism affecting the teeth without other anomalies (E-WJ). We describe a Chilean case in a 12-year-old with the typical dental alterations and with histopathologic findings that include absence of predentin layer and prominent reduced enamel epithelium. E-WJ is not a syndrome and we propose "multiple macrodontic multituberculism" as a better name for this anomaly of uncertain etiology affecting only the crowns of the teeth.
BACKGROUND: The proportion of dental causes of maxillary sinusitis is estimated between 10% and 40%. The mechanisms are manifold and originate from the close relation of the side teeth and the maxillary sinus. In the past, the transantral approach was commonly used by maxillofacial surgeons as their first choice. PATIENTS AND METHODS: Between 01/1999 and 10/2001 38 patients underwent endoscopic surgery controlled via the fossa canina. Apart from the mandatory treatment of the dental focus and the mucosal pathologies, a fenestration to the middle meatus of the nose was performed in 7 cases. RESULTS AND CONCLUSION: The dental medical history, OPG, CT scans in coronary plane, endoscopic findings, and histology showed the commonly "silent" course of dental sinusitis. Typical findings in CT scans are unilateral basal maxillary opacities adjacent to the molar and premolar teeth. In 20% of the cases there was also a blockade of the infundibulum. All patients were reexamined 6-12 months postoperatively. The patients are free of symptoms, but sometimes suffer from headaches. An exact diagnosis and the clear separation of rhinogenic causes are vital points for the therapy of dental sinusitis. In cases of unilateral sinusitis, a comprehensive investigation by the maxillofacial surgeon should be recommended. Video-assisted endoscopic sinus revision is preferable to the transantral approach and is especially suitable for the treatment of mucosal retention cysts, the removal of foreign bodies, endoscopically controlled resections of apical roots, elevations of the sinus floor, and dental implants. If the ethmoidal infundibulum and maxillary ostium are open, no fenestration is needed. In cases of blockade, fenestration to the middle nose canal is indicated.
