In animal models, bone preservation has been demonstrated by a femoral bone preparation using a compaction technique. In terms of migration, epidemiological, and radiological results, there are no significant long-term differences between compaction and broaching techniques for primary total hip arthroplasty. Methods: A total of 28 patients were treated with one-stage bilateral THA with cementless femoral stems on a single patient. Overall, 13 patients were missing to the ten-year sequel, with 30 hips failing to be assessed in terms of stem migration, radiologic advancement, Harris Hip Score, Oxford Hip Score, and complications. Conclusion: Following the use of compaction and broaching techniques of the femur in a long-term follow-up, similar stem subsidence, radiological, and clinical outcomes were found.
This randomized clinical trial was intended to determine the 3-year survival rates of high viscosity glass ionomer restorations in primary molars using conventional cavity preparation and a traumatic restorative technique. Materials and Methods: In this RCT, 139 schoolchildren aged 6–9 years with dentinal caries in primary molars were randomly assigned to groups, i. e. Using a random number generator, the ART group and the conventional group are divided into two groups, as well as the conventional group. Both groups recovered after using standard techniques, but GC Fuji IX ART HVGIC was used as restorations. Conclusion: GIC restorations using GC Fuji IX ART HVGIC were extremely successful, according to a three-year follow-up, establishing the use of ART for the primary dentition in areas with high caries prevalence and poor access to dental services in areas with high incidence of dental care in areas with high prevalence and limited access to dental care.

Background Information The effectiveness of various types of teeth has yet to be determined, but the effectiveness of endodontics treatment has yet to be determined. This research aims to determine the reliability of three dimensional -printed endodontic guides for access cavity preparation in various types of teeth, as well as the ability of canal accessibility in ex vivo. Method Eighty-four extracted human teeth were mounted into six jaw models and categorized into three groups: anterior teeth, premolar, and molar. Tomography and surface scans were taken and matched using implant planning software, according to the Preoperative cone beam computed tomography and surface scans. In SPSS v20, the receiver operating characteristic curve was used to determine the predictive capability of angular and linear deviation for canal accessibility. After canal negotiations, the canals were open after canal negotiations, but they were not accessible after canal negotiations. A total of 117 guided access cavities were created, 23 of which were historic as canal inaccessibility, and 23 of them were set as canal inaccessibility, but all canals were accessible. The linear deviations of the AT and P groups were significantly lower than M group deviations at the coronal location, but there was no statistically significant difference between AT group and P group at the coronal position, but not significantly different between AT group and P group. Conclusions In conclusion, this review found that the accuracy of access cavity preparation with 3D-printed endodontic guides was acceptable. The M group had significant linear and angular deviations that were much higher than those in other groups, which could have been attributed to the mixing of the opposite teeth. The canal access capability of guided access cavity preparation was best represented by Angular difference.
