RESUMO
Ameloblastic carcinoma (AC) is an uncommon malignant odontogenic tumor, with about 200 cases published in the literature. Here, we report a case of AC occurring in the maxilla - at the same anatomical location of an ameloblastoma 8 years earlier. A 23-year-old woman with maxillary swelling of 6-month duration was referred to our service. Extraoral examination revealed a swelling over the right side of the face, lifting her lip and nose. Intraorally, a firm, reddish, nodular swelling involving the right maxilla was observed. Computed tomography showed a hypodense image invading the right maxilla, maxillary sinus, and nasal fossa. An incisional biopsy was performed, followed by histopathologic examination and an immunohistochemical panel, which led to the diagnosis of AC. The lesion was treated with partial maxillectomy followed by immediate rehabilitation. Neither local recurrence of the tumor nor distant metastasis was observed during a 4-year follow-up. AC is a highly malignant lesion which requires aggressive therapy. Its diagnosis should be based on combined clinical, imaging, and pathological manifestations in order to improve diagnostic accuracy.

PURPOSE: The purpose of this study was to verify the influence of prebrushing mouthwashes on dental plaque removal in children. METHODS: This study had a double-blind, randomized, controlled, crossover, 25-day experimental design, including 38 12- to 14-year-olds. Four solutions were used as prebrushing mouthwashes (Colgate Plax Magic, Listerine Cool Blue Agent, water and dye, and water) by each participant with seven days' washout. The plaque index was evaluated before and after tooth-brushing during the experimental period. RESULTS: Intergroup comparisons showed no significant differences in plaque reduction among evaluated solutions (Friedman test, P>.78). Significantly more plaque was present before vs. after tooth-brushing (Wilcoxon rank test, P<.001), independent of the surface (buccal or lingual/palatal). CONCLUSION: Use of prebrushing mouthwashes by children does not influence plaque removal by tooth-brushing.
