fa Case Series: Conditions Inhibiting Eruption of Permanent First Molars کودکان Pediatric Dentistry پژوهشي Research <p> <strong>Purpose:</strong></p><p>  The purpose of this study was to evaluate the radiological and histopathological findings of 11 patients with unerupted first molars to verify the factors obstructing spontaneous eruption. </p><p> <strong>Methods:</strong></p><p>  The patients' clinical, radiological, and histopathological data were evaluated retrospectively to determine histopathological diagnosis, radiographic findings, methods of surgical management, and postoperative course. </p><p> <strong>Results:</strong></p><p>  This study involved 4 male and 7 female patients (mean age=9.5 years old). Nine cases involved the mandible. The patients' histopathological diagnoses included 3 odontogenic tumors, 2 odontogenic cysts, and 6 hyperplastic dental follicles. Radiographically, 10 cases showed characterless enlargement of the follicular space, while only 1 displayed radiopaque bodies. One patient with a tumor underwent enucleation, and 1 with a cyst underwent cystectomy and tooth extraction. The others underwent wide excision or partial excision of the surrounding tissue at the top of the impacted tooth. Tumor relapse was observed in 3 cases. </p><p> <strong>Conclusion:</strong></p><p>  Surgeons should perform aggressive treatment for patients with unerupted teeth because spontaneous eruption is rare in cases involving non-neoplastic lesions such as hyperplastic dental follicles. </p><hr><p></p><p> <strong>Source: </strong>Journal of American Academy of ‍ Pediatric Dentistry</p><p><a href="http://www.ingentaconnect.com/content/aapd/pd/2013/00000035/00000001/art00013jsessionid=u5n10ezntvyo.alexandra" target="_blank"><font color="#0000ff"> Full Text</font></a></p> IMPACTED; MOLAR; ODONTOGENIC CYCTS; ODONTOGENIC TUMORS; UNERUPTED 0 0 http://idai.ir/browse.php?a_code=A-10-32-2528&slc_lang=fa&sid=1 Hidenobu Matsuzaki 100319475328460012024 100319475328460012024 Yes Department of Oral Diagnosis and Dentomaxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan Yoshinobu Yanagi 100319475328460012025 100319475328460012025 No Department of Oral Diagnosis and Dentomaxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan NAoki Katase 100319475328460012026 100319475328460012026 No Departmentof Oral Pathology and Medicine, Drs., Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan Hitoshi Nagatsuka 100319475328460012027 100319475328460012027 No Departmentof Oral Pathology and Medicine, Drs., Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan Marina Hara 100319475328460012028 100319475328460012028 No Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan Masakazu Ashida 100319475328460012029 100319475328460012029 No Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan Teruhisa Unetsubo 100319475328460012030 100319475328460012030 No Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan Akiko Sato 100319475328460012031 100319475328460012031 No Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan Mariko Fujita 100319475328460012032 100319475328460012032 No Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan Toshihiko Takenobu 100319475328460012033 100319475328460012033 No Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan
