Objectives: An umbrella review is a systematic review of systematic reviews, which provides a tertiary level of evidence. This umbrella review of systematic reviews and meta‐analysis (SR‐MA) aimed to determine the proportion of oral cancer (OC) development in oral submucous fibrosis (OSF) patients. Materials and Methods: We searched electronic databases including PubMed, Scopus, Web of Science, Cochrane and grey literature. Two reviewers independently screened abstracts and assessed for eligible papers. The methodological quality of SR‐MA was evaluated using AMSTAR2, and we also checked the quality of evidence of the included papers. Results: Out of 454 papers identified in the primary search, 105 underwent eligibility screening. Inclusion criteria were met by four SR‐MA. OC ratios ranged between 4.2% and 6% for OSF. Substantial heterogeneity was observed for this outcome in all four MA (I2 = 71.31% to 86.37%). None of the SRs assessed the quality of evidence, and half of them were judged to be of critically low methodological quality. Conclusion: There is lack of quality of evidences and critically low methodological quality among SRs and MA leading to substantial heterogeneity. However, due to potentially malignant nature, OSF patients should be monitored carefully for early detection of OC. [ABSTRACT FROM AUTHOR]

Objective: According to findings from the previous studies, quitting smoking can significantly reduce mortality from all causes and is linked to better treatment results. Even though quitting smoking has many benefits, little is known about the evidence supporting the particular quit services offered to smokers after a cancer diagnosis. Methods: To find the articles related to area in question, different electronic databases including PubMed/Medline, Google Scholar, and EBSCO were searched on April 1st, 2023. All full text randomized controlled trials with one or more intervention and control groups that assessed the outcomes of smoking cessation interventions were included. Participants of included studies were adults diagnosed with head and neck cancer (HNC) and current smokers or those who had recently quit. There were interventions (pharmacological and/or pharmacological) that aimed to help patients with HNC succeed in quitting smoking. Results: We identified 15352 papers from the initial search from different electronic databases, 2560 remained after excluding duplicates. After screening titles and abstracts for relevance, 2345 articles were removed. Full text articles of remaining 215 papers were assessed in depth by two reviewers for their eligibility, amongst which, 210 articles were excluded. Finally, we included five papers that met the inclusion criteria in the present systematic review. Conclusion: According to the findings of this review, a multi - component strategy might very well benefit patients with HNC who smoke cigarettes after diagnosis. More studies with high methodological quality and standardized outcome measures must be conducted in this population to inform the development of smoking cessation program. [ABSTRACT FROM AUTHOR]

Background: Pregnancy is a time of increased susceptibility in terms of dental health due to typical physiological changes. Pregnant women with better oral health are less likely to experience pregnancy-related dental disease problems. Methodology: This cross-sectional study was conducted at college of dentistry, Qassim university, Qassim province of Saudi Arabia. A piloted tested self-administered questionnaire was used to collect data which was available in Arabic and English languages. Data collection was done through social media platform among pregnant women. Pearson's chi-square test was used to analysehe difference of opinions among different trimester of pregnant women's. Result: In the present study, 208 pregnant women's responded to online forms through social media platform, with mean age of participants was 33.10 ±8.11. Significantly, higher number of second trimester woman reported dental problem and majority of them attended private dental clinic. The majority of women's were dissatisfied about the instruction given by gynecologist for dental care. But surprisingly, significantly higher number of women were aware about the aware about eruption time of baby tooth and harmful effect of bottle-feeding. Conclusion: Saudi women's oral health knowledge and practices need to be improved in order to prevent dental and oral diseases and to motivate them to receive routine dental care in order to ward off additional illness.

Background: There is a lack of information in the few studies reporting on the use of three-dimensional (3D) Printing for Patient Management. However, few studies have been found about recent advances in 3D printing technology, and biomaterials are revolutionizing medicine. The purpose of this study is to evaluate the knowledge and attitude of new generation dentist towards 3D printing and its application in various aspects in the field of Prosthodontics. Materials and Methods: A cross-sectional study on dental practitioners/Prosthodontist throughout Saudi Arabia using a self-administered questionnaire, which had items to assess the knowledge attitude and practices of study participants toward the use of 3D printing in dental management. Results: It was observed 17.5% of our participants had complete information and 10.5% had no information about 3D printers in the field of dental medicine. When assessed, male dentists had complete information about 3D printers (17.5%) than females (0%). 43.9% of our participants "strongly agreed" for 3D printers to be implemented in dentistry, 40.4% had "no idea" regarding the experience of 3D prints. Conclusion: Very few dentists have knowledge of 3D printing application in dentistry. Hence we strongly recommend organizing continuing dental education programmed on 3D printing either with hand on workshops, conferences and regular updates on the use of this technology.

Dense Ba1-xPbxTiO3 (x = 0–0.20) samples (>90% TD) were fabricated through a solid-state reaction route involving wet ball milling for 24 h and calcination at 1150°C for 4 h, followed by sintering at 1300°C for 4 h. XRD results for all the samples revealed a tetragonal perovskite (P4mm) crystal structure. Increased substitution of Pb caused monotonic growth in the tetragonality character of the perovskite phase. Although, the value of εrʹ dropped from an initial value of 3000 for x = 0 (pure BaTiO3) to 400 for x = 0.20 samples, the losses (tanδ) interestingly declined almost to half. A substantial increase in the Curie temperature from 120°C for x = 0°C to 180°C for x = 0.15 samples was noted. P-E loop analysis revealed an increase in the saturation polarization by almost 1.5 times, moreover, in the remnant polarization by six times with Pb-substitution. The d33 values demonstrated an increase from 95 pC/N for pure BaTiO3 samples to 220 pC/N for x = 0.15 samples. [ABSTRACT FROM AUTHOR]
