Abstract Objective This study compares three types of esthetic crowns in fracture resistance force (FRF) and failure type: (1) polymethylmethacrylate (PMMA) milled by computer-aided design/computer-assisted manufacture (CADCAM), (2) resin-based material via three-dimensional (3D) dental printer, and (3) direct composite celluloid crowns technique in primary molars. Material and Methods Thirty lower second primary molar were randomized into three experimental groups consisting of ten molars for each: group A:CADCAM crowns using PMMA blocks; group B: 3D dental printer to fabricate crowns using glycidyl carbamate photopolymer resin; group C: Selected teeth crowned using direct resin composite celluloid crowns. The three groups (A, B, and C) were stored in water at 37°C for 30 days. The FRFs for the experimental crowned teeth were measured using a universal test machine (Testometric) until fracture and the values compared with the mean maximum bite force of children in the primary dentition. FRFs and failure types were recorded and statistically analyzed. Results One-way analysis of variance (ANOVA) revealed significant differences among the groups in FRF testing. Bonferroni test was used for multiple-correction comparison in comparing force needed to fracture the specimens in the three groups. A significant difference was noticed between groups B-C (p = 0.000) and groups A-C (p = 0.000). No significant statistical differences were noted between groups A-B (p = 0.325) in FRF scores. In failure type, no statistical differences were noted when comparing groups, A and B, groups B and C, but comparing groups A and C showed statistical differences in chi-square statistical test. Conclusion The three tested esthetic crowns exceeded the mean maximum bite force of children in the primary dentition; thus, they can be expected to perform well clinically. Even though using an indirect technique (CADCAM milling and 3D printer) showed a higher score in FRF, direct composite celluloid crowns technique can be beneficial since it is easier to repair and still is a useful modality.

Abstract Objective Oral health reflects the physical and mental health of the individual as it is the first line of entrance of bacteria into the body. Knowledge regarding oral health is an essential component for dental as well as medical faculty as they are responsible for maintenance of health of the individual in clinical and nonclinical practices. Therefore, the aim of the study was to determine the predominance of oral hygiene with dental brushing, flossing, smoking, usage of mouthwash, and frequency of dental visits. Materials and Methods To achieve the aim of the study, a questionnaire was created to access the awareness of oral hygiene status among medical and dental faculty. The study was conducted at Sir Syed College of Medical Sciences and all the faculty staff from senior faculty to junior staff was included in the study. Results A total of 200 participants participated in the study of which 125 were females (62.5%). The results specify that the female faculty members have a better oral hygiene knowledge as compared with male faculty members. Single faculty members or staff visit a dentist more as compared with married faculty members or staff as single staff has more time and less responsibilities at home. Knowledge regarding oral hygiene care of overall participants is satisfactory. Conclusion In conclusion, the oral health care and knowledge is far better in dental faculty member as compared with medical faculty member as the oral care is the substantial component of the dental core curriculum.

Abstract Dental caries is the most prevalent disease in primary, mixed, and permanent dentition. Many preventive and treatment strategies were used in the last decades. Silver diamine fluoride (SDF) is a promising nontoxic material which proves to be a turning point concerning conservative dentistry if the patient and dental practitioners are adequately educated regarding it. Several advantages have been reported related to the use of SDF, including the procedure being pain-free and drill-free, patient- and doctor-friendly caries control strategy, and management of dentinal hypersensitivity.

Abstract Objective To assess the patient’s level of awareness of dental implants as an option to replace missing teeth and willingness to accept dental implant is lacking in a small city (Chitwan) Nepal. Materials and methods A cross-sectional survey was conducted on patients attending the prosthodontic, oral medicine and radiology clinics of Chitwan Medical College, Chitwan, Nepal. A self-administered questionnaire was used after pretesting through a pilot survey. The data analysis was done using SPSS version 20 (IBM Company, Chicago, USA). Statistical Analysis Various parameters were compared using Two-Sample Independent T-Test. The level of significant was set at p value = 0.05. Results A total of 84 subjects responded to the study. Only 47.6% of the participants have knowledge on dental implants. Majority of the participants (72%) considered the costs to be affordable and equal number of the participants replied that they were ready for treatment with dental implant. Majority of the participants received information from their dentists (53.1%) and from the friends and acquaintances (31.3%). The patients in Chitwan have moderate awareness of dental implants. Majority of the participants are aware and willing to consider dental plant treatments. Conclusions The patients in Chitwan have moderate awareness of dental implants. Majority of the participants are aware and willing to consider dental plant treatments. Proper information on dental implants should be provided to the patients so that they can accept the dental implant treatment.

Abstract Objective This study aimed to assess the perception of factors affecting studies and well-being among students of the Bibi Aseefa Dental College, Larkana, Sindh, Pakistan. Materials and Methods Students of the Bibi Aseefa Dental College of various professional years were asked to respond to an online-based survey (Google Forms), which was then evaluated by SPSS 16.0 (SPSS Inc.; Chicago Illinois, United States) using the analysis-of-variance test. The study sample consisted of stratified random sampling. Inclusion criteria included students from year 1 to year 4 of their undergraduate studies during the study period of June 2019 to August 2019. Descriptive statistics including frequency and distribution regarding gender, year of study, age, external factors (stress, sleep, health, hobbies, financial, friends, paid work, voluntary work), reasons for choosing dentistry, and how these factors affecting the study were created. Results The results showed that 97 students chose Bachelor of Dental Study (BDS) as a career because they were not selected in Bachelor of Medicine and Bachelor of Surgery (MBBS). Overall, 52.41% students agreed that external factors are affecting their studies, 46.8% stated that they were stressed due to studies in past 12 months, 48.4% students agreed that their disturbed sleep due to academic assignments is affecting their studies, 29.9% stated that their health disturbance affected their studies in the past 12 months, and 48.4% responded that their own hobbies and sports work were affecting their academic grades. Conclusion This study revealed that extracurricular factors were a cause of stress among dental students. The main cause of stress among the student was confusion about the syllabus of their academic year, resulting in a lack of sleep during the examination year, and favoritism among teachers for the students.
