Indiana University-Purdue University Indianapolis (IUPUI) / This investigation served as a follow-up of the unilateral and bilateral cleft lip and palate patients who underwent primary alveolar bone grafting at James Whitcomb Riley Hospital of the Indiana University Medical Center. The sample consisted of 18 patients, 15 males and three females, who received primary alveolar grafts between September 7, 1983 and March 5, 1985. Thirteen had complete unilateral clefts, and five had complete bilateral clefts of the lip and palate. The mean age of the group was 8 years, and none had received orthodontic treatment. The statistical analysis of the lateral cephalometric radiographs revealed significant differences in maxillofacial growth between the Riley sample population and the non-cleft, age-matched patients in the University of Michigan Growth Study. The Riley data were, overall, statistically and proportionately smaller than the normal population. These findings are due to the smaller skeletal size of the Riley group. Arch symmetry measurements indicated that at 8 years of age there were significant differences from ideal or perfect symmetry. Due to existent dental development and scarring from the palatal procedure, these findings were expected. Ideal symmetry may not be a realistic achievement for the cleft patients. Palatal surface area values were visually analyzed through graphs. The growth patterns of the Riley population were similar to those of the normal and non-grafted cleft groups in a study from the University of Miami. The data supports the theory that primary alveolar bone grafting, as performed at James Whitcomb Riley Hospital, does not result in growth attenuation.

Background   Decision-making within the dental field is an essential factor that influences every aspect of the profession. It is of absolute importance for patients to receive the most suitable treatment for their individual situation. Aim The aim of this study was to examine whether dentists in the county of Västerbotten, Sweden, made suitable therapy choices when faced with teeth with diseases in the dental pulp or in the periradicular tissues. Methods  This was executed by analyzing data from patient journals and deciding whether the chosen treatment was the optimal one or if considered questionable. When faced with questionable treatment choices, the aim was to determine if there was a common denominator between these cases.  Factors taken in consideration when analyzing the journals were the patient’s sex and age, the tooth treated, the total number of teeth including wisdom teeth, x-ray images, cause of the treatment, sex of the dentist responsible and a description of case. In total, 360 patients were analyzed, and 51 were excluded. Result  The result showed that 95% of the analyzed patient cases had a suitable treatment. Conclusion The conclusion was that dentists in Västerbotten make good treatment choices and that it is not possible to draw any conclusions regarding the questionable treatments.

Objectives: This study aims to examine malocclusion traits of a racially diverse population to determine the validity of the malocclusion prevalence reported in the NHANES III survey. Additionally, the cephalometric database from the American Association of Orthodontists Foundation Legacy Collection (AAOF-LC) was used for skeletal malocclusion prevalence. The sample used data collected at the Temple University orthodontic screening clinic (TUKSoD) from 2012-2020.Methods: Malocclusion prevalence of the TUKSoD population (n=7713) was compared to the NHANES III (n=7000) and AAOF-LC (n=1198) for dental and skeletal traits respectively. The TUKSoD population is 51.5% Black, 38% Hispanic, 2.7% White, 1.1% Asian, 0.2% American-Indian, and 1.1% other; age range 6-78 (mean 21.05±10.47), 60.4% females/39.6% males. The AAOF-LC is comprised primarily of Caucasian patients; age range 1-47, 48% females/52% males. The NHANES III survey included Black, Caucasian, and Mexican-American participants, with results weighted to represent American population demographics. Traits were compared in the transverse (dental), vertical (dental/skeletal), and sagittal (dental/skeletal) planes. Prevalence was recorded as percentage of the total population. Results: Significant differences were found for all dental comparisons: Sagittal (Class-I,II,III; p=8.59E-7), Vertical (Open-bite/Deep-bite; p=1.53E-13), and Transverse (crossbites). Significant differences were found for all skeletal comparisons: Sagittal (Class-I,II,III; p=5.38E-6), and Vertical (Open-bite/Deep-bite; p=8.89E-5). Conclusion: TUKSoD serves a diverse patient population which has significantly different skeletal and dental malocclusion prevalence compared to the control populations. These differences are likely the result of the genetic influences underlying the demographics. As the NHANES III and AAOF-LC represent common standards, comparison to genetically heterogenous contemporary populations is challenging, underscoring the need for more personalized approaches to determining malocclusion demographic characteristics. / Oral Biology
