Feldspathic ceramic (Vita Triluxe Forte), hybrid resin ceramic (Vita Enamic), and lithium disilicate glass-ceramic (IPS e.max CAD) were used in this study. A CAD/CAM system and 81 (27 of each material) samples of ceramic blocks were used. All samples were immersed in black coffee for 15 days, and the coffee was changed twice per day. Using a spectrophotometer probe, samples on a grey background were scanned, and physical properties like surface hardness and depth were measured using interferometry and a 3D non-contact surface metrology. After 30 days of application of oral hygiene tools, instruments were used to measure various physical, mechanical, and optical properties. Vita Triluxe had the highest average color variation values (ΔE 00) after 15 and 30 days of immersion in coffee in both regular and electronic toothbrushes. Moreover, IPS e.max CAD had the least ΔE 00 values with no significant differences among the groups. The surface roughness (Ra) of the Vita Enamic ceramic increased when using a regular toothbrush, and the surface height (Rz) for the Vita Enamic ceramic increased when an electronic toothbrush was used. IPS e.max CAD had the greatest modules of elasticity forces, and Vita Triluxe Forte had the lowest when used with a regular toothbrush. The ΔE 00 values of the tested materials were minimally increased or decreased after 30 days of cleaning, and all were clinically acceptable. Ra and Rz were the highest for Vita Enamic in comparison to the other groups. The highest percentage in IPS e.max CAD was associated with a type 1 fracture, whereas type 3 was predominantly observed with Vita Enamic, and type 2 in the Vita Triluxe group without significant differences.

Materials and Methods: A cross-sectional questionnaire-based study was conducted among a convenient sample of 320 parents/guardians. All the parents/guardians willing to participate in the study and whose children visiting the dentist for the first time were included in the study. Children's behavior was assessed using Frankl's scale. Results: Majority (29%) of the children visited the dentist for the first time at the age of 3–6 years, while the least percentage (8%) visited the dentist for the first time at the age of 0–1 year. A statistically significant difference was found between the responses (P ≤ 0.05). Most (72.67%) of the children were being accompanied by parents during their first dental visit. About 40.33%...

Research paper thumbnail of Treatment of Cases with Different Grades of Fluorosis by Lithium Disilicate Glass-Ceramic CAD/CAM Materials: A Case Report of Two Cases

Dental fluorosis is considered to be the most common color disorders of the enamel. It presents with different clinical signs on the enamel of the patients. The diagnosis of dental fluorosis is very challenging in the clinical practice since the enamel defects could be confusing. This case report presented two cases and their treatment for different grades of dental fluorosis to improve the esthetic appearance of the teeth.

Material/Methods: PubMed, ScienceDirect, Scopus, Wiley Library, and Web of Science databases were searched using keywords and Medical Subject Headings. Identified studies were in English, published between 2008 and 2022, measured the burnout of healthcare workers and students by using CBI and MBI, and observed adverse patient outcomes. Results: A total of 38 studies were included in the current review. All included studies assessed and evaluated subjects and participants by observing clinical measures, personal and demographic data, countries where the study was conducted, and study type used. Fifty percent of CBI papers were conducted in Saudi Arabia and other Arab countries, whereas the majority of MBI papers (10) were conducted in Europe, followed by 9 studies conducted in Saudi Arabia and other Arab countries and 6 studies conducted in the USA and Canada. The overall percentage of burnout in CBI studies (53%) was higher than that in MBI studies (35%). Also, the types and domains in CBI were marginally higher than those in MBI. Conclusions: Studies that used CBI scales recorded higher burnout compared with studies that used MBI. Females, higher education levels, and marriage status of the tested subjects showed higher CBI and MBI scale scores in comparison to their counterparts. Higher significant differences percentages in burnout types and genders were recorded in CBI than in MBI.

Research paper thumbnail of The Effect of Intraradicular Multiple Fiber and Cast Posts on the Fracture Resistance of Endodontically Treated Teeth with Wide Root Canals

The endodontically treated teeth (ETT) with thin remaining radicular dentin thickness are predisposed to fracture; hence it requires the diligent selection and the execution of endodontic post treatment. The objective of the study was to evaluate the reinforcing effect of both multiple fiber reinforced composite (FRC) and Ni-Cr cast metal posts at anterior and posterior regions. Material and Methods. Forty recently extracted root canal treated canine and single rooted premolar teeth were used for the study. They were randomly divided into four groups (n=10) as: Group 1, single FRC post; Group 2, multiple FRC posts; Group 3, single Ni-Cr metal post, Group 4, multiple Ni-Cr posts. The posts were cemented with self-adhesive resin cement and subsequently restored with full veneer metal crown. The compressive static load at 1300 for canine and 450 for premolar was applied with the cross-head speed of 0.5mm/minute until the fracture. The obtained data was analyzed using the ...

Research paper thumbnail of An Anthropometric Study of Cranio-Facial Measurements and Their Correlation with Vertical Dimension of Occlusion among Saudi Arabian Subpopulations

The improper VDO compromises the aesthetics, phonetics and functional efficiency of the prosthesis. Various methods are suggested to determine the accurate VDO, including the facial measurements in the clinical situations with no pre-extraction records. The generalisation of correlation between the facial measurements to VDO is criticised due to gender dimorphism and racial differences. Hence, it is prudent to verify the hypothesis of facial proportion and correlation of lower third of the face to remaining craniofacial measurements in different ethnic groups. The objective of the study was to evaluate the correlation of craniofacial measurements and OVD in the Saudi-Arabian ethnic group.METHODOLOGY: Total of 228 participants from Saudi-Arabian Ethnic group were randomly recruited in this cross-sectional study.

The posts were cemented with self-adhesive resin cement and subsequently restored with full veneer metal crown. The compressive static load at 130 0 for canine and 45 0 for premolar was applied with the cross-head speed of 0.5mm/minute until the fracture. The obtained data was analyzed using the Kruskal-Wallis and Pairwise comparison tests with SPSS. Results. The results indicate that multiple FRC post restored canine had the maximum fracture load (1843.80±7.13 N), followed by cast multiple posts (1648.99±26.84 N), single fiber post (1623±40.31 N), and cast metal single post (1493±27.33 N). A similar trend was observed in premolar with higher max fracture load with multiple FRC posts at 1920.86±20.61 N and multiple cast metal posts at 1735.43±6.05 N. Conclusion. The restoration of ETT with larger canals by multiple FRC and metal posts provides substantially higher fracture resistance in comparison to wider single post.
