Likewise, it has to witness the dynamic changes in its diagnosis method and treatment planning. The field of orthodontics has witnessed many revolutionary techniques and evolved enormously in terms of benefiting the patient. CAD/CAM is one promising methodology that has shown a significant impact in modern dentistry and surpassed some of the challenges an orthodontist has been facing all these years. It has changed the view through which we see the patient’s condition. The application of 3D technology allows the practitioner and patient to utilize virtual treatment planning software to better identify case objectives and visualize treatment outcomes. CAD/CAM has many applications in orthodontics, which include aids for diagnosis and treatment planning, clear aligner treatment, customized lingual appliances, customized brackets with patient-specific torque, machine-milled indirect bonding jigs, robotically bent archwires, indirect bonding systems, customization of orthodontic appliances like distalization appliance etc., Acceleration of orthodontic treatment (OT) has received growing attention in recent years, especially in adult patients.Digital workflow is the current trend in orthodontic practice and has speckled every aspect of orthodontics in terms of documentation, study casts, analysis of dental malocclusion, smile designing, treatment planning and fabrication of orthodontic appliances. The current article aimed to establish a narrative description of the digital workflow and applications of the CAD/CAM process in Orthodontics.","PeriodicalId":132317,"journal":{"name":"International Journal of Dental Materials","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129243382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the key elements that makes up the smile frame is tooth size. The maxillary front teeth are the most noticeable in the smile arch, therefore choosing the right tooth size and positioning it in the maxilla improves both aesthetics and treatment outcomes.Aim:This study aimed to compare the dimensions of maxillary anterior teeth measured with vernier callipers and CHU proportion gauge with facial proportions such as intercanthal distance, interalar width and bizygomatic width.Materials and Methods:On a sample of 100, Facial proportions, mesiodistal width, and height of maxillary anterior teeth were recorded using digital callipers and a Chu proportion gauge. The recorded data were subjected to statistical analysis. Mean comparisons of each width were done using a t-test, ANOVA and Tukey’s Post-hoc test considering a p-value less than 0.05 to be statistically significant. Results:Mean values of the combined width of anteriors calculated using Chu gauge was 45.08, and that calculated using Vernier Callipers was 45.85. Multiplying the factor 1.47 to Inner canthal width and 1.42 to Interalar width results in the combined width of the maxillary anterior teeth. A mean difference of 0.02620 ± 0.91777 and 0.4988 ± 0.91777 exists between Inner canthal and Combined Chu’s width with a 0.04% and 0.34% error in younger and elder age populations, respectively. A mean difference of -11.4775 ± 0.91777 and -11.6039 ± 0.91777 exists between Combined mesiodistal width obtained by using Chu’s width and bizygomatic width witha 0.01% error in younger and elder age populations, respectively.Conclusions:This study reported a negligible 0.7 difference in the means of the combined width of anteriors calculated using Chu gauge and Vernier Callipers. Hence, these two methods can be used as alternatives to calculate the width of anterior teeth","PeriodicalId":132317,"journal":{"name":"International Journal of Dental Materials","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133265649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dental plasters exhibit poor mechanical properties. Aim: This study aimed to evaluate the physico-mechanical properties of dental plaster modified with various concentrations of pulverized acrylic waste. Materials and Methods: A total of 120 specimens were fabricated using dental plaster and were divided into four groups of 30specimens each to evaluate setting time, one-hour compressive strength, 24-hour compressive strength, and surface reproducibility. Each group was subdivided into five groups of six specimens (n=6), each with the incorporation of various concentrations of pulverized acrylic powder. The specimens incorporated with various concentrations of pulverized acrylic powder (0.5 wt%, 1.0 wt%, 5.0 wt% and 10.0 wt%) were considered as modified groups and the dental plaster with no additives was considered as a control group. The initial and final setting times were measured using a Gillmore needle apparatus, the compressive strength was measured using a universal testing machine, and the surface reproducibility was analyzed using a stereo microscope. The obtained data were subjected to statistical analysis using one-way ANOVA and post hoc analysis. Results: The incorporation of 0.5 wt% resulted in more final and initial setting times. The one-hour and 24-hour compressive strengths of the dental plaster increased with increasing concentration of acrylic waste. Poor surface details were observed with an increase in the concentration of acrylic waste. Conclusions:The addition of acrylic waste resulted in an increase in the one-hour and 24-hour compressive strengths, decreased initial and final setting times, and poor surface reproducibility.","PeriodicalId":132317,"journal":{"name":"International Journal of Dental Materials","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127359792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PMMA has been widely used in a range of dental applications because of its specific features, including its low density, aesthetics, cost-effectiveness, ease of manipulation, and flexible physical and mechanical characteristics. Despite having many advantageous qualities, it has a lot of cons like weak flexural strength, poor wear resistance, polymerization shrinkage, and poor durability etc., The emergence of nanotechnology has allowed for the improvement of the afore-mentioned drawbacks through the use of different nanoparticles. Silver nanoparticles have been used in dentistry due to their antimicrobial, and antifungal properties. They also enhance the mechanical properties of materials leading to improved outcomes. Gold nanoparticles are available in different sizes and concentrations to exhibit their beneficial outcomes.

During such repairs, these cements are invariably exposed to irrigating solutions.Aim:This study aimed to understand the effect of irrigating solutions on the hydration of calcium silicate cements. Materials and Methods:Sixty extracted teeth were taken and horizontal sections of 2mm were obtained. These samples were randomly divided into two groups viz. Biodentine and BioMTA Plus groups later these cements were condensed into the canal spaces and allowed to set until their setting time. These samples were further subdivided and allowed to encounter three irrigating solutions viz. Normal saline, 17% EDTA, and 2% Chlorhexidine for 5 minutes. These were allowed to mature in an incubatorfor seven days and subjected to Scanning Electron Microscopy and Energy Dispersive X-ray analysis.Results: The SEM analysis of the Biodentine/control group displayed a petal-like appearance, with a Ca/Si ratio of 2. Whereas, the Biodentine/Normal saline,Biodentine/17% EDTA and Biodentine/2% Chlorhexidine group displayed crumbled paper-like appearance. The Ca/Si ratios for the Biodentine/Normal saline, Biodentine/17% EDTA and Biodentine/2% Chlorhexidine were 2.72, 1.6, and 4.21,respectively. In the BioMTA Plus group, all the SEM analyses displayed round crystalline structures in all groups. The Ca/Si ratio of BioMTA Plus/Control,BioMTA Plus/17% EDTA and BioMTA Plus/2% Chlorhexidine were25.5, 17.42, 24.1, and 39.4, respectively.Conclusion:The study concluded that the irrigating solutions did not affect the hydration mechanism of Biodentine and BioMTA Plus despite the variations in the Ca/Si ratios and surface morphology.","PeriodicalId":132317,"journal":{"name":"International Journal of Dental Materials","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114675082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
