A case of an intranasal tooth associated with cacosmia in a 5-year-old patient with cleft lip and palate is reported. Several previous surgeries had been performed to correct the patient’s cleft. The patient was evaluated by computed tomography, and the tooth was removed from the nostril. The etiology of this phenomenon is discussed. Salvador

The aim of the present study was to compare postoperative effects of celecoxib (200 mg/day) and ibuprofen (1,800 mg/day) on trismus, swelling, pain and quality of life of patients subjected to extraction of third molars. A randomized double-blind clinical trial was conducted. Fifteen patients were submitted to extraction of impacted third molars, right and left, at different times. Oral dexamethasone (8 mg) was given preoperatively and for postoperative analgesia, celecoxib was administered for one side tooth extraction and ibuprofen for the other. Pain, swelling, trismus and quality of life were scored with a visual analogical scale (VAS), facial linear measurements and Oral Health Impact Profile questionnaire (OHIP-14). Trismus did not significantly differ between the groups. Angle of the mandible to the nasal border distance was significantly lower in the ibuprofen group at 0.5 h and 48 h. OHIP-14 total score was significantly lower in the ibuprofen group at 48 h, where differences occurred for functional limitation, physical pain and physical disability domains. No significant differences occurred at the other OHIP-14 times and domains. Pain VAS was significantly lower in the ibuprofen group at 4, 8, 24, 48 and 72 h. Swelling VAS was significantly lower in the ibuprofen group at 2, 6, 12, 72 and 96 h. Rescue medication was more often in the celecoxib group, but without significant difference considering the number of tablets used. Frequency of infection and duration of surgical procedure did not significantly differ between the groups. A extração de terceiros molares constitui procedimento cirúrgico frequente e de significativa morbidade durante o período pós-operatório. O presente estudo teve por objetivo comparar o efeito pós-operatório dos fármacos celecoxibe (200 mg/dia) e ibuprofeno (1.800 mg/dia) sobre os parâmetros trismo, edema, dor e qualidade de vida em paciente submetidos a exodontias de terceiros molares. Um estudo clínico randomizado duplo-cego foi conduzido, em que 15 pacientes foram submetidos a exodontias de terceiros molares, dos lados direito e esquerdo, em diferentes momentos. Os pacientes receberam 8 mg de dexametasoan por via oral no pré-opratório e, para analgesia pós-operatória, celecoxibe foi administrado para um lado das extrações e ibuprofeno foi administrado para o outro. Dor, edema, trismo e qualidade de vida foram avaliados por meio de escala analogica visual (VAS), medidas faciais lineares e pelo inventário Oral Health Impact Profile (OHIP-14). O trismo não diferiu significativamente entre os grupos. A distância ângulo da mandíbula-asa do nariz (Go-Al) foi significativamente menor para o grupo ibuprofeno nos períodos de 0.5 h e 48 h. O escore total do OHIP-14 foi significativamente menor no grupo ibuprofeno no período de 48 h, sendo verificadas diferenças significativas para os domínios limitação funcional, dor física, e incapacidade física. Não ocorreram diferenças significativas para os demais períodos e domínios do OHIP-14. A VAS de dor foi significativamente menor no grupo ibuprofeno nos períodos 4, 8, 24, 48 e 72 h. A VAS de edema foi significativamente menor no grupo ibuprofeno nos períodos 2, 6, 12, 72 e 96 h. A frequência de uso da terapia analgésica de resgate foi maior no grupo celecoxibe, mas sem diferença significativa para o número de comprimidos usados. A frequência de infecção e a duração da cirurgia não diferiram significativamente entre os grupos.

The study sample comprised 12 patients with complete unilateral pre-incisive foramen clefts treated at the Hospital de Reabilitação de Anomalias Craniofaciais (Universidade de São Paulo, Bauru). Films and scans were manipulated by software packages. Cleft area was calculated with each diagnostic modality, and cleft volume, by CBCT. Measurements were obtained from axial CBCT slices, 3 mm and 6 mm above the cementoenamel junction and at the level of the apex, for assessment of the thickness of the alveolar ridge adjacents to the cleft. Four measurements were obtained from the panoramic CBCTs for measurement of the length of cleft-adjacent roots and alveolar ridges. The results showed that CBCT was significantly superior to occlusal and panoramic radiographs for measurement of cleft area, with mean measured values of 803 mm2, 40. 36 mm2, and 50. 84mm2 respectively (p≤0,05, Student's t test), and 889. 9 mm3 for volume measurement. Mean root length of the teeth mesial and distal to the cleft was 9. 91 mm and 10. 56 mm respectively, and mean bony coverage of the roots, 73. 73% and 86. 38% respectively. We conclude that CBCT was able to reveal a significantly larger bone defect area than occlusal or panoramic radiographs; allowed measurement of root and bony ridge lengths in the areas adjacent to clefts, as well as more accurate measurement of bone thickness around the roots of teeth, enabling improved planning of the amount of bone required for secondary alveolar bone grafting procedures; and provided clearer, more faithful reproductions of the details of the cleft area, with no overlap of anatomical structures. A presente pesquisa avaliou as fissuras e as estruturas anatômicas adjacentes através das técnicas radiográficas oclusal e panorâmica e da tomografia computadorizada de feixe cônico (TCFC) por meio de uma análise descritiva e de mensurações lineares e volumétrica. Participaram do estudo 12 pacientes portadores de fissuras pré-forame incisivo unilaterais completas em tratamento no Hospital de Reabilitação de Anomalias Craniofaciais da Universidade de São Paulo – Bauru/SP. As imagens radiográficas e tomográficas foram manipuladas por softwares. As áreas das fissuras foram calculadas nas três modalidades diagnósticas e o volume na TCFC; foram realizadas medidas axiais nas tomografias nas alturas de 3mm e 6mm acima da junção cemento-esmalte e ao nível dos ápices dentários para análise das espessuras das cristas ósseas adjacentes às fissuras; quatro medidas na vista panorâmica das TCFCs para medição do comprimento das raízes e das cristas alveolares adjacentes às fissuras. Os resultados mostraram a superioridade da TCFC em relação as radiografias oclusal e panorâmica na determinação das áreas das fissuras com valores médios de 803mm2, 40,36mm2, 50,84mm2, respectivamente, apresentando diferença estatisticamente significativa (teste t-student, p≤0,05), e 889,9mm3 para as medidas de volume. Os dentes mesiais e distais aos defeitos apresentaram médias do comprimento radicular de 9,91mm e 10,56mm e da cobertura óssea radicular de 73,73% e 86,38%, respectivamente. Concluiu-se que a TCFC revelou um defeito ósseo significativamente maior que os observadas nas radiografias oclusal e panorâmica; possibilitou a mensuração da extensão das raízes dos dentes e suas respectivas cristas ósseas adjacentes às fissuras; permitiu a mensuração da espessura óssea ao redor das raízes dos dentes, possibilitando melhor planejamento da quantidade óssea a ser utilizada nas cirurgias de Enxerto Ósseo Alveolar Secundário; e reproduziu os detalhes da região da fissura com maior nitidez sem sobreposição das estruturas anatômicas.

The sample comprised 27 white patients, at ages ranging from 17 to 40 years, 12 females and 15 males. All patients were adults presenting deficiency in the transversal maxillary growth, they hadn’t been subjected to previous orthodontic treatment and needed SA-RME for their orthodontic treatments. Linear and angular measurements were obtained from lateral and posteroanterior cephalometric tracings and statistically analyzed in the early phase, shortly after the stabilization of the Hirax appliance and at 3 months of retention. The SA-RME promoted an increase in the in the widths of the apical bone base of the maxilla (p
