Aim:The aim of our study is to evaluate the changes in quality of life among patients treated for maxillary midline diastema by fixed orthodontic appliances.Materials and Methods:This prospective longitudinal study consists of 40 patients of age group 20-30 years who underwent orthodontic correction of midline diastema. The patient's quality of life is evaluated using 22-item orthognathic quality of life questionnaire. They were evaluated prior to appliance therapy, 1 month after appliance fixation, 4th and 8th month during treatment and 1 month after treatment.Results:Our results showed moderate improvement in quality of life as early as at the start of orthodontic therapy. The response was equal among both sexes. The quality of life experience improved only mildly during the orthodontic treatment. However, the condition specific quality of life at the end of appliance therapy improved by nearly 50% when compared with prior to treatment.Conclusion:Our study has concluded that the correction of midline diastema has improved the quality of life among young people by nearly 50%. The acceptance to orthodontic therapy and patient perception toward fixed appliance has demonstrated remarkable improvement in quality of life during the treatment. Our study calls for additional patient counseling and motivation during the course of fixed appliance therapy.

Background: Nutrient foramen is an opening over which the nutrient artery enters and supplies the shaft of the long bones. The nutrient foramen usually lies near the soleal line and transmits a branch of the posterior tibial artery. The posterior tibial artery is a branch from the popliteal artery. The nutrient vessel may also arise at the level of the popliteal bifurcation or as a branch from the anterior tibial artery.Methods: The present study was conducted on 200 dry human tibia bones of unknown sex and age. The tibia bones were observed for nutrient foramen macroscopically.Results: In our study the right sided 7 tibia bones and 6 left sided tibia bones have double nutrient foramen. The position of the nutrient foramen in the upper 1/3 rd is observed in 77.47% tibia and in the middle 1/3 rd in 17.84% of the tibia.The direction of the nutrient foramen is downwards in all the tibia bones Conclusions: The tibia is the most commonly fractured long bone and contributes significantly to the fracture care worldwide. Fracture of the tibia through the nutrient canal disrupts the blood flow in the nutrient artery, thus contributing delayed union and non-union of the bone. Knowledge of the blood supply and location of nutrient foramen is important in the treatment and planning of surgery in fractures.

Introduction: The best treatment for the deeply carious tooth that cannot be restored is by the root canal therapy. This method has saved many patients from the loss of tooth. The common practice is either to deliver a full crown or close the access cavity with restoration. Hence in this study, the clinical longevity of the routine practice is tested for by analyzing the fracture toughness and the survival of the teeth that were restored endodontically with various materials. Materials and Methods: The hospital records were retrospectively evaluated from 2000 to 2010 for a decade. The demographics as well as the survival and the failure rates noted and compared for the various types of the restorations. The number of the walls of the teeth was also compared. Results: Thousand teeth were considered in the study. Less than 7% of teeth had coronal fractures. Of the 93% teeth that had survived, the most common restoration was Individual post (+ crown) followed by GIC, amalgams, and crowns. The mean survival of the crown+ bridge & gold restoration was highest. The mean survival was 10 ± 2 years for the restored teeth without any fractures at the coronal level. The failure was greatest for the GIC followed by amalgam, and the variations when compared with other restorations were significant. There was no significant difference for the number of the walls on the crown; however, the number of walls present was proportional to the survival rate. Conclusion: The teeth that were covered with a crown were comparatively fracture resistant and had a better survival rate compared to other restorations. GIC showed highest fracture, and the post core with crown had the best survival. Restoration of the lost crown architecture and the reinforcement are the best methods that can be followed for the survivals.
