Objective: To evaluate the changes in dimensional accuracy of dental gypsum casts after immersion in stable chlorine dioxide (SCD) disinfectant solution.
Methods: Each of 90 specimens was made of type III,type IV and type V dental stone, respectively,which were further divided into 9 groups (n=10). The gypsum casts were immersed in 3.71,7.41 and 11.12 mmol/L SCD disinfectant solution for 5, 10 and 15 min, respectively. The dimensional accuracy of dental gypsum casts were measured with outside diameter in micrometer before and after immersion. The data were analyzed using analysis of variance (ANVOA) at 95% confidence level.
Result: There were no significant changes in dimensional accuracy of all dental gypsum casts treated by same concentration of SCD solution for 5, 10 and 15 min. And the dimensional accuracy of all dental gypsum casts treated with different concentrations of SCD for the same duration did not change.
Conclusion: SCD disinfectant solution has no impact on dimensional stability of dental gypsum casts.

Evaluation of the accuracy of a simplified hybrid method versus the traditional digital method for measuring palatal volume.
J Oral Biol Craniofac Res
November 2024
Ramaiah University of Applied Sciences (RUAS), Bengaluru, India.
Objective: This study aimed to compare a direct conventional 3D digital technique vis a vis a hybrid method in measuring palatal volume.
Materials And Methods: Thirty maxillary casts were obtained from the records of patients undergoing orthodontic treatment and pre-conceived boundaries of the palatal vault were marked. Sample was categorised into Group I (Volume estimation using CBCT scan) and Group II (Volume estimation using hybrid method).
Assessment of Iatrogenic Damage to Adjacent Teeth After Applying Different Prevention Methods: A Cross-Sectional Study.

Aim: This study aimed to assess the iatrogenic damage to adjacent dental surfaces when using different prevention methods.
Methods: Fifty gypsum casts were evaluated in this cross-sectional study, and a total of 50 posterior teeth that required full crown preparation to receive fixed prostheses were included in this study. The casts were assigned into two groups.
Calcium sulfate-based load-bearing bone grafts with patient-specific geometry.

The treatment of bone defects with complex three-dimensional geometry presents challenges in terms of bone grafting and restoration. In this paper, we propose a rapid and effective method that uses 3D printing, ceramic casting, and the incorporation of mesh reinforcement to create load-bearing bone grafts with patient-specific three-dimensional geometry. Using two types of facial bones as examples, we show that this fabrication method has a high degree of geometrical fidelity.

Statement Of Problem: Prosthetic screw loosening is a common mechanical complication of implant-supported fixed dental prostheses. Although techniques for detecting screw loosening in single implant-supported fixed dental prostheses have been reported, studies on the screw stability for splinted implant-supported fixed dental prostheses are lacking.
Purpose: The purpose of this in vitro study was to determine whether acoustic resonance frequency analysis using a newly developed system could detect prosthetic screw loosening in splinted implant-supported fixed dental prostheses.
