Although both materials share similar esthetic properties but have different mechanical properties which could affect their mode of failures. Therefore, the aim of the study was to analyze the failure modes of zirconia versus PolyEtherEtherKetone custom made posts in anterior endodontically treated teeth. Materials and Methods: Thirty-six anterior maxillary incisors with similar dimensions were collected, decoronated, endodontically treated, and post space prepared. The teeth were divided according to material of post into two groups: group (1) PolyEtherEtherKetone post and group (2) zirconia post. PolyEtherEtherKetone posts were surface treated via sulfuric acid while zirconia posts were sandblasted by 50um aluminum oxide particles. All posts were cemented using dual cure self-adhesive cement. Thermocycling at 5,000 cycles was done to all samples. Three slices of 2mm thickness were obtained from each sample. The samples were loaded to failure via universal testing machine at a crosshead speed of 0.5 mm/min. Failure modes were evaluated using a scanning electron microscope under magnifications of 52x, 250x and 400x. Results: There was no statistically significant difference between failure modes of the two post material types at the cervical, middle as well as apical root levels (P-value = 0.070), (P-value = 0.580) and (P-value =","PeriodicalId":120858,"journal":{"name":"MSA Dental Journal","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139328799","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}

Methods: Thirteen edentulous patients received two implants each in the intra-foraminal region of the mandible, with SLA in the left side of the midline, laser-treated implants in the right side and ball stud attachments for the overdenture. The overdentures were early loaded after 6 weeks. Implants survival rate was evaluated over a12 months follow up period using image analysis software (Digora Optime, Soredex). The statistical software SPSS (Statistical Package for the Social Science; 22.0, IBM Corp, Armonk, NY, USA) was utilized for data analysis. Implant survival rates were calculated using the Kaplan-Meier analysis. Results: After 12 months follow up period, the implants survival rate was 92.3%. The overall mean survival times of the implants was 11.269 m. For the laser-treated implants and SLA the mean survival times were 11.308 and 11.231 months respectively.

Digital transformation in the orthodontic field fundamentally alters the way in which orthodontic treatment is perceived, delivered, and helps in creating individualized orthodontic appliances. Fully equipped orthodontic office with intraoral scanners and 3D printers enhances diagnostic procedures and treatment planning abilities through implementing digital photos digital models, digital cephalometric analysis, and virtual setups, ending up with dental monitoring software analyzing tooth movement using artificial intelligence, manufacturing of custom-made brackets, robotically bent wires, 3D printed appliances like 3D printed facemask, which makes the device more comfortable to the child’s face with sensors allows orthodontist to measure compliance, clear aligners, indirect bonding trays, and retainers.

Motivation to adopt the science of ergonomics correctly is still lacking among dental students. Methods: Dental students at Modern Sciences and Arts University were given a self-administered survey. In total, sixty-two people took part in this survey. Participants were asked to complete a structured online questionnaire containing 18 questions regarding their MSDs symptoms, intensity and frequency. The data was collected within two weeks starting from the 1st of January 2023 until the 14th of January 2023, to be analyzed and surveyed. Results: Lower back pain was the most frequently reported musculoskeletal disorder among all dental students, while workload had a significant impact on these conditions. Female dental students experienced a greater intensity of pain and increased pain sensitivity, even though both sexes experience it in the same areas of the body. There was a direct relation between physical activity and experienced chronic pain in the lower lumbar region of the back among dental students. Conclusions: The majority of students appear to work in environments that exacerbate musculoskeletal system disorders. It is advised to incorporate ergonomics principles into routine work and practice regular physical activity. To create a comfortable working environment; dental ergonomics should be taught to undergraduate students and strictly implemented in the clinics.","PeriodicalId":120858,"journal":{"name":"MSA Dental Journal","volume":"313 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123150846","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}
