RESUMO

The purpose of this study was to analyze the volume and area of sphenoid sinuses of Brazilian individuals' cone-beam computed tomography (CBCT) images using the beta version of the DDS-Pro™ 2.14.2_2022 software (DPP Systems, Czestochowa, Poland), to assess a potential correlation to sex, age, skin color, and nutritional status, and to evaluate differences between the right and left sides. Three-dimensional volume and area measurements were made with the software using CBCT images of 113 living Brazilian individuals of both sexes (67 females and 46 males). TEM, rTEM, and R were used to assess the reproducibility of inter- and intra-examiner measurements. The measurement means were estimated with 95% confidence intervals according to sex and age group. There were no significant differences between the left and right sides for both volume and area and between the sexes and black and white individuals. Volume and area were significantly higher in 18 years or older (p < 0.05) and in individuals with normal body mass index (BMI) (p < 0.05). The obtained results do not allow indicating the use of sphenoid sinuses volume and area measurements to estimate sexual dimorphism, and the same occurred for skin color. However, such measures can help to estimate age. Further studies are suggested with a larger sample, especially for the nutritional status variable.

RESUMO

BACKGROUND: Age is important in forming the uniqueness of individuals. When chronological age is not available, age estimation is required, particularly in court cases. The mineralization chronology of permanent teeth is a valuable tool for age estimation of subadults. This study aimed to evaluate the mineralization stages of permanent teeth of Brazilian subjects from imaging exams, using the classification by Moorrees et al. modified by the authors, to verify the existence of correlation between the chronology of mineralization stages and sex and to prepare numerical tables of the chronology of dental mineralization stages for Brazilian individuals. METHODS: Digital panoramic radiographs of 1100 living Brazilian individuals of both sexes, aged between 2 and 25 years, born between 1990 and 2018, from the image bank of a Dental Radiographs and Documentations clinic located in the city of Araraquara, SP, Brazil. The images were evaluated according to the level of crown and root development and classified according to the stages proposed by Moorrees et al. (Am J Phys Anthropol 21: 205-213, 1963) adapted by the authors. All analyses were performed in the R software. Descriptive and exploratory analyses were performed on all data. For intra- and inter-examiner analyses, the rate of agreement and Kappa statistics at a 95% confidence interval were used. Kappa was interpreted according to Landis and Koch. RESULTS: Only upper and lower canines showed significant differences between the sexes (p < 0.05), with higher average ages for men. The findings were presented in tables, as well as age estimates with 95% confidence intervals for each mineralization stage and each tooth. CONCLUSION: In the present study, we evaluated the mineralization stages of permanent teeth of Brazilian subjects from digital panoramic radiographs and found no correlation between the chronology of mineralization stages and sex, except for canines. From the obtained results, numerical tables of the chronology of dental mineralization stages were prepared.

RESUMO

OBJECTIVE: To perform three-dimensional measurements (volume and area) of the maxillary sinus, from cone-beam computed tomography (CBCT) images, and to assess potential differences between the left and right sides and a correlation of the measurements to sex, age, skin color, and nutritional status. DESIGN: CBCT images of 161 living Brazilian subjects of both sexes (89 women and 72 men) were used, and three-dimensional measurements of volume and area were made with the beta version of the DDS-Pro™ 2.14.2_2022 software (DPP Systems, Czestochowa, Poland). The inter- and intra-examiner reproducibility of measurements was evaluated with TEM, rTEM, and R. RESULTS: Both maxillary sinus volume and area did not show significant differences between the left and right sides and between the sexes. Volume and area were significantly lower in the age group from 6 to 11 years than in the other two groups (p < 0.05). The measurements obtained for maxillary sinus volume and area were significantly higher in white individuals (p < 0.05), but they did not show significant differences (p > 0.05) regarding nutritional status (considering the body mass index - BMI). CONCLUSION: There were no statistically significant differences between the sexes, which does not allow recommending the use of maxillary sinus volume and area measurements to analyze sexual dimorphism, and the same occurs for BMI. However, such measures can help to estimate the age and skin color of individuals.

RESUMO

As alterações alveolares após a exodontia de um elemento dental desafiam a Implantodontia na busca por técnicas e materiais que devolvam ao rebordo alveolar os tecidos perdidos com previsibilidade e menor morbidade ao paciente. Este relato de casos clínicos mostra a instalação de implantes imediato ou tardio, associados ou não ao procedimento de carga imediata utilizando o enxerto misto da tuberosidade maxilar como alternativa viável para essas reconstruções, tendo como objetivo principal a redução do número de procedimentos cirúrgicos e a previsibilidade no período pós operatório. O osso da tuberosidade maxilar é composto por uma fina camada de osso cortical externo e medular interno que apresentam alta capacidade de revascularização e integração à área receptora. A vantagem em se manter o periósteo entre o enxerto corticomedular do túber e o tecido conjuntivo é conter a reabsorção óssea periosteal na região cervical e melhorar a qualidade do tecido mole. A limitação do uso da tuberosidade maxilar está relacionada a sua dimensão, que pode permitir a reconstrução de um ou dois dentes por área doadora ou, em alguns casos, pode não haver área doadora disponível. As características únicas da tuberosidade maxilar de fornecer osso corticomedular e tecido conjuntivo subepitelial permitem a sua associação no enxerto misto de túber e mostra grande versatilidade para a reconstrução dos tecidos duros e moles, permitindo técnicas refinadas capazes de solucionar casos complexos em um único procedimento cirúrgico...

Alveolar alterations after extraction constitute a challenge and lead to the search for techniques and materials to reconstruct the lost tissues with previsibility and less morbidity to the patients. These case report shows the placement of immediate implants, delayed implants, with or without the immediate loading procedure and maxillary sinus lift with immediate implant placement using the maxillary tuberosity mixed graft as a viable alternative to these reconstructions aiming to reduce the number of surgical procedures and improve predictability in the post-operative period. The tuberosity jaw bone consists of a thin outer layer of cortical bone and inner medullary bone that have a high capacity of revascularization and integrating into the receiving area. The advantage of keeping the periosteum between tuberosity corticomedular graft and the connective tissue is to contain the periosteal bone resorption in the cervical area and improve the quality of the soft tissue. Limitation to the use of maxillary tuberosity is related to their dimensions that may allow the reconstruction of one or two teeth per donor area or, in some cases, it may not be available. The unique characteristics of the maxillary tuberosity to provide corticomedular bone and subepitelial connective tissue allow their association in the maxillary tuberosity mixed graft and show great versatility for the reconstruction of hard and soft tissue, allowing refined techniques to solve complex cases in a single surgical procedure...

RESUMO

Era abril de 1996, na cidade de Campinas, em São Paulo. Dizia-se que aquele era o primeiro curso de especialização em Implantodontia do Brasil — na época, coordenado pelos Profs. Vicente de Souza Pinto e Carlos Alberto Dotto. A turma estava repleta de colegas dos quatro cantos do país, todos radiantes com a oportunidade de termos sido aprovados em uma seleção com mais de 80 candidatos para 12 vagas. Tínhamos um objetivo comum: desvendaros mistérios da nova especialidade que ora se apresentava. Vivíamos em um tempo no qual a cirurgia, em osseointegração, ainda não conhecia os princípios do planejamento protético, e o aumento ósseo alveolar era um procedimento distante. A literatura sobre o assunto, ainda com característica embrionária e incipiente, forçava-nos a conceber o manual Clinical decision making and treatment planning in osseointegration (Engelman MJ, 1996) como‘best-seller’ internacional. Esse grupo tinha um colega especial: José Scarso Filho. Especial,porque ele era especial: discreto e educado, parecia entender a ansiedade e as inseguranças dos companheiros. Era jovem mas comportava-se como uma pessoa vivida. Preferia não estar em evidência — por timidez, talvez —, mas não conseguia. Tinha carisma, inteligência e uma habilidade manual descomunal. Era um cirurgião bucomaxilofacial refinado e experiente, mas gostava de conversar sobre resinas compostas e preparos protéticos. Não podia ver instrumentais cirúrgicos de qualidade, e não fazia contas nem economia ao adquiri-los. Na verdade, não podia ver nada bom que, imediatamente, queria usar, fosse na fotografia, informática ou na Odontologia. Tinha sede de conhecimento e parecia não ter limite em “querer aprender”. Autodidata, parecia humildemente “tudo saber”. O resultado foi que, em bem...

April, 1996, Campinas, São Paulo. The first specialization course on Implantodontics tookplace in Brazil under the coordination of Profs. Vicente de Souza and Carlos Alberto Dotto.The class was made up of students coming from all over the country, all of which were over joyed for being approved in a selection process involving more than 80 applicants applying for 12 vacancies. All of us shared a common objective: Solve the mysteries of the new specialty. At that time, osseointegration surgery had not met the principles of prosthetic planning, and alveolar bone augmentation was a remote procedure. The literature was germinal and incipient, forcing us to conceive the “Clinical decision making and treatment planning in osseointegration”(Engelman MJ, 1996) as the international best-seller. This group had a special guest: José Scarso Filho. And he was indeed special: discreet and polite, he seemed to understand the feelings of anxiety and insecurity shared by his colleagues. He was young, but behavedas an experienced man. He would rather not be in the spotlight, perhaps for being shy, buthe could not help it. He was charismatic and intelligent, and had extraordinary manual dexterity.At that time, he was an accurate and experienced oral and maxillofacial surgeon whoenjoyed talking about composite resin and prosthetic preparation. He was eager to acquirehigh-quality surgical instruments and made no savings when doing so. In fact, as soon as hewas introduced to an innovation, be it in photography, information technology or Dentistry,he was keen to use it. He had a thirst for knowledge and had no limits in learning. A selftaughtperson, he humbly seemed to know everything. The end result was that, in no time, he...

RESUMO

OBJETIVO: Verificar o comportamento biológico de um sistema de placas e parafusos de procedência nacional. METODOLOGIA: Foram utilizados 6 cães adultos, mestiços, machos, com peso corporal variando entre 8 e 11 kg, onde sob anestesia geral foi realizada a implantação de uma placa com quatro parafusos 2,0 mm na mandíbula direita, com proservação por um período de 60 dias. Após este período, os tecidos foram enviados para análise histológica. RESULTADOS: Os resultados evidenciaram uma reparação óssea ao redor do parafuso de titânio com formação de tecido ósseo de padrão lamelar, e em algumas regiões do tecido esponjoso, uma delgada camada de fibras colágenas recobrindo partes do parafuso. Observou-se sobre a placa uma espessa camada de tecido fibroso, e, na superfície em contato com a estrutura óssea foi observado reabsorção óssea com substituição por tecido conjuntivo fibroso. CONCLUSÃO: O material testado apresenta biocompatibilidade; há a formação óssea em contato com os parafusos

RESUMO

A finalidade deste estudo foi verificar a capacidade de osseoindução do complexo BMP, em 6 coelhos brancos (New Zealand) que foram divididos em 2 grupos: grupo de enxerto de osso autógeno e grupo de BMP. Foram utilizados um total de 12 implantes de titânio puro, 2 em cada metáfise proximal da tíbia esquerda. Foram confeccionados defeitos ósseos de 2,5 x 4mm expondo as roscas dos implantes, que foram preenchidos com os 2 tipos de materiais estudados (osso autógeno e BMP). Os animais foram sacrificados 42 dias após a implantação e os espécimes foram processados para análise histológica. A substituição do material de enxerto e a neoformação óssea foram observadas em ambos os grupos. Concluiu-se que tanto o enxerto ósseo autógeno como o complexo BMP apresentam muito bom comportamento biológico, induzindo a neoformação óssea ao redor do implante.

The aim of this study was to verify the capacity of osseoinduction of the 6 white rabbits BMP complex (New Zealand) that were divided in 2 groups: group graft of autogenous bone and group of BMP. It was used a total of 12 implants of pure titanium, 2 in each proximal metaphysis of the left tibia. It was confectioned bone defects of 2.5 x 4mm exposing the threads of the implants, which were filled with the two types of the materials studied (autogenous bone and BMP). The animals were sacrificed after 42 days of the implantation, and the specimens were processed to histologic analysis. After 42 days substitution of the grafted material and bone neoformation were observed in both groups. It was concluded that both autogenous bone graft and BMP complex present a very good biological behavior, inducing bone neoformation around the implants.
