Orthodontic treatment in the adult is not new. Until lately, the challenges of treating the adult patient kept their numbers low. Over the last thirty years, however, there has been a steady increase in the prevalence of adults seeking orthodontic treatment. Many adults present with a mutilated dentition that often require a multidisciplinary approach for optimal treatment outcomes. Currently, guidelines for the evaluation of adult orthodontic treatment outcomes do not exist. The purpose of this study was to determine which factors are considered most important for the evaluation of the quality of adult orthodontic treatment outcome of patients with a mutilated dentition by practicing orthodontists, periodontists, and restorative dentists. In this study, orthodontists, periodontists, and restorative dentists examined the records of ten adult patients in the mutilated dentition who received orthodontic treatment at Temple University in the Department of Orthodontics. This study was approached from both a quantitative and qualitative perspective. Two surveys were used to collect the data. One survey used a visual analogue scale to measure the overall result, occlusion, buccal bone height, periodontal health, restorability, case difficulty, and the amount of influence of the American Board of Orthodontics (ABO) standards when judging the cases. A second survey was used to determine if the examiner was ABO certified and asked a series of open-ended questions related to orthodontic treatment outcome. Based on the data collected, the following conclusions were drawn: 1. Orthodontists, periodontists, and restorative dentists are consistent in their rating of orthodontic treatment outcome. 2. Periodontists and restorative dentists rate overall case finish and posttreatment occlusion higher than orthodontists. 3. When evaluating case finish, orthodontists tend to blend what is optimal as described by the guidelines of the American Board of Orthodontics with what is reasonably achievable for the patient. 4. Orthodontists, periodontists, and restorative dentists rate the following five factors to be most important when evaluating orthodontic treatment outcome: esthetics, occlusion, restorability, periodontal health, and stability. 5. Orthodontists, periodontists, and restorative dentists rate esthetics as the most important factor to use for evaluating orthodontic treatment outcome. The data suggest that adult patients with mutilated dentitions can pursue orthodontic treatment and achieve an excellent result. Teamwork among all dental specialists providing treatment is essential for multidisciplinary treatment. Treatment goals among all providers must be aligned to reach the ultimate treatment goals. / Oral Biology

Resumo: Estudos mostram que os traumatismos na dentição decídua são comuns, podendo trazer também comprometimentos aos dentes permanentes em desenvolvimento. O propósito desta pesquisa foi avaliar os traumatismos em dentes decíduos e as seqüelas nos dentes permanentes sucessores, em crianças atendidas no Pronto Atendimento da Bebê Clínica, da Universidade Estadual de Londrina, entre os anos de 1992 a 2002. Da análise de 1703 prontuários que apresentavam relato de traumatismos nos dentes decíduos, 864 atenderam os critérios de inclusão propostos para este estudo, sendo que 409 crianças foram localizadas e compareceram ao local de exame. Os prontuários destas crianças foram estudados a fim de se obter informações a respeito do trauma. O exame clínico e radiográfico foi realizado com o objetivo de verificar as seqüelas nos dentes permanentes em decorrência dos traumatismos nos antecessores decíduos. Para a análise destas seqüelas, a amostra foi dividida em 2 grupos, sendo o Grupo I constituindo as crianças com apenas uma ocorrência de traumatismo nos dentes decíduos e o Grupo II, aquelas com mais de uma ocorrência. A freqüência de injúrias traumáticas nos dentes decíduos foi de 31,9% no total dos 1703 prontuários avaliados. Das crianças examinadas, o gênero masculino foi o mais acometido (57%) e a idade da criança no momento do trauma entre 6 e 24 meses, a mais observada (38,4%). As quedas de uma forma geral, e entre estas, aquelas causadas pelo andar e correr foram os fatores etiológicos mais predominantes (37,8%). O tempo decorrido entre o trauma e a procura por atendimento foi mais averiguado no periodo de até 1 dia (43,5%). Dos 679 dentes decíduos avaliados, o incisivo central superior direito foi o mais afetado (42,0%) e a subluxação, o tipo de traumatismo mais prevalente ...(Resumo completo, clicar acesso eletrônico abaixo) / Abstract: Studies show dental trauma in primary teeth as common happening and the risk of compromising the permanent teeth in developing process. The purpose of this research was to evaluate the dental trauma in primary teeth and its sequelae in the successor permanent teeth in children attended at Pronto Atendimento da Bebê Clínica, State University of Londrina, from 1992 to 2002. From the analysis of 1703 children presenting cases of dental trauma in primary teeth, 864 attended the criteria of inclusion proposed to this study. From the total above 409 children were located and came to the examine place. The data of these children were studied in order to obtain precise information regarding trauma. The clinical and radiographic exams were carried out with the objective to verify sequelae in the permanent teeth due to traumas caused on the predecessor deciduous. For the analysis of these sequelae the sample was divided into 2 groups: Group I, consist of children with only one occurrence of trauma in the primary teeth and group II, of those with more occurrences. The frequency of traumatic injuries in the deciduous teeth was 31,9% in total of the 1703 cases evaluated. From the examined children, masculine gender was the most compromised (57%) and the age of the child in the moment of the trauma was between 6 and 24 moths (38,4%). Falls in general, among those caused by walking and runnings were the etiologic predominant factors (37,8%). The time between trauma and seeing the dentist was done in a period of a day (43,5%). From 679 deciduous teeth evaluated, the right maxillary central incisor was the most affected (42,0%) and the subluxation, type of trauma more frequent (32,5%). In regard to the treatment recommended to the primary teeth monitoring was the most used ...( Complete abstract click electronic address below) / Orientador: Robson Frederico Cunha / Coorientador: Antônio Ferelle / Banca: Farli Aparecida Carrilho Boer / Banca: Célio Percinoto / Banca: Robson Frederico Cunha / Mestre

Background: Dental trauma occur in childhood and adolescence with consequences in time and costs for both patient and family. The scientific knowledge of these matters is scarce. For some individuals, dental trauma will result in long, time-consuming and costly treatments in childhood which will continue into adulthood. Aim: The thesis aimed to increase the knowledge of incidence, risk, treatment, time and costs spent on dental traumas to primary and permanent teeth in children and adolescents. Material and method: The material for the studies emanated from the county of Västmanland, Sweden, and the municipality of Copenhagen, Denmark, and from a Swedish nation-wide material (Folksam). The material was collected from accident reports, dental files, dental trauma forms, questionnaires and telephone interviews. Descriptive, prospective and analytical methods were used. A classification of uncomplicated and complicated dental traumas was presented. Results: The incidence of dental trauma to boys was higher, compared to girls, in the county of Västmanland in almost all age groups. For both sexes, the first years in life and the first years in school were the most accident prone periods with incidence twice as high as the average incidence for all children and adolescents in the county. Every third trauma was complicated with injuries to the pulp or periodontal ligaments. Every second patient with a dental trauma to permanent teeth suffered from multiple dental trauma episodes (MDTE) during a period of 12 years. In almost every second patient with MDTE, at least one of the affected teeth had sustained repeated trauma episodes. The risk of sustaining MDTE increased when the first trauma episode occurred in the age interval of 6-10, compared to 11-18 year olds. During a 12-year period, treatment times for complicated traumas were 2.0 and 2.7 times higher for primary and permanent teeth, respectively, compared to corresponding values for uncomplicated traumas. On average, direct time (treatment time) represented 11% and 16% of the total time, while the direct costs (health are service, transport, loss of personal property and medicine) represented 60% and 72% of the total costs of traumas to primary and permanent teeth, respectively, during a 2-year period for cases of a nation-wide material. Conclusion: Dental traumas are frequent and some individuals are injured several times. Besides treatment time, efforts from the family are substantial in time and costs. Parameters such as degree of severity, access to treatment and place of injury are of major importance to both patient and family and should be considered when calculating time and costs of dental trauma in children and adolescents.

Dental morphology and tooth shape have been used to recreate the dietary adaptations for extinct species, and thus dental variation can provide information on the relationship between fossil species and their paleoenvironments. Variation in living species with known behaviors can provide a baseline for interpreting morphology, and behavior, in the fossil record. Tooth occlusal surface outlines in hominins and non-hominin primates, and other mammals, have been used for assessments of taxonomic significance, with variability often considered as being primarily phylogenetic. Few studies have attempted to assess how diet might influence the pattern of variability in closely related species. Here the occlusal surface shape variability in anterior and postcanine maxillary dentition in primates is measured to assess whether the relationship between diet and variability is consistent. Data were collected from five non-hominin primates in a range of dietary categories, as well as two hominin species, including the derived Paranthropus robustus and a gracile australopith. Mapping a series of 50 sliding semilandmarks based on 2-D photographs using tpsDig software, occlusal surfaces were outlined. Thereafter, outline shapes were quantified using Elliptical Fourier Functional Analysis, and principle components and multivariate analyses were preformed to explore the pattern of intra and interspecific variability in occlusal outlines.These results suggest that there is not a clear relationship between dietary feeding adaptations for all categories examined and selection for larger premolars and molars, as well as smaller incisors, led to less variation in both anterior and post-canine teeth of the fossil hominin Paranthropus robustus.
