1/3. Formation of a cyst-like area after a connective tissue graft for root coverage.BACKGROUND: Many techniques have been developed to obtain root coverage. There have been few complications reported with these techniques. This case report chronicles the development of a cyst-like area after a connective tissue partial-thickness double pedicle graft was used to obtain root coverage. methods: The root coverage procedure was performed as previously reported. Postoperatively, in the surgical area, the patient developed occasional swelling. It was possible to express a white material from the area. A biopsy was taken to determine the cause of the clinical findings. RESULTS: Histological evaluation revealed the development of a cyst-like area. CONCLUSION: The development of cysts does not seem to be a common event. However, this case report demonstrates that they are a possible complication of root coverage procedures.- - - - - - - - - - ranking = 1keywords = connective (Clic here for more details about this article) |
2/3. Mandibular infected buccal cyst or a paradental cyst?: Report of a case.The mandibular infected buccal cyst occurs on the buccal and distal aspects of the roots of the partially or newly erupted first permanent molar. It typically affects children between the ages of 6 to 10 years and the associated first permanent molar is vital. The cyst is lined with a non-keratinised squamous epithelium with inflammatory cell infiltrate in the connective tissue. Most clinical and histological features are similar to those reported for paradental cysts.- - - - - - - - - - ranking = 0.2keywords = connective (Clic here for more details about this article) |
3/3. Pigmented lateral periodontal cyst and other pigmented odontogenic lesions.OBJECTIVE: To report a case of lateral periodontal cyst (LPC) with marked melanin pigmentation in a 38-year-old Black male and to discuss the phenomenon of melanin pigmentation in odontogenic cysts and tumors. RESULTS: Histologically, the epithelial lining of the LPC contained an abundant amount of melanin granules throughout the entire epithelium. Ultrastructurally, epithelial cells contained mature melanosomes (stage IV melanosomes). Melanophages containing aggregates of melanosomes were identified in the connective tissue cyst wall. Perusal of the literature revealed that melanin pigmentation in odontogenic lesions is uncommon. Melanin has been reported in calcifying odontogenic cyst (18 cases), odontogenic keratocyst (8 cases), adenomatoid odontogenic tumor (3 cases), ameloblastic fibroma (3 cases), odontoma (2 cases), and ameloblastic fibro-odontoma, odonto-ameloblastoma, and odontogenic fibroma (1 case each). CONCLUSIONS: Almost all pigmented odontogenic lesions; occurred in Blacks and Asians; they are almost non-existent in Whites. Thus, racial pigmentation probably plays an important role in such lesions.- - - - - - - - - - ranking = 0.2keywords = connective (Clic here for more details about this article) |
