RESUMO

Child abuse and neglect (CAN) have significant consequences for children's health and well-being. Dentists play an important role in identifying and reporting CAN cases. This study aimed to assess knowledge and attitudes toward CAN among dental students. A cross-sectional study was conducted among dental students, comparing second-year (preclinical) and fifth-year (clinical) students, both male and female, in the College of Dentistry at King Saud University during the first semester of the 2022/2023 academic year, using a questionnaire with 23 multiple-choice questions and an electronic link. The results revealed that most dental students (96%) were aware of CAN, with social media being the most utilized source of information (85%). However, the dental college was noticed as the least utilized source (50%). Most dental students recognize the significance of CAN in dentistry and expressed an intense interest in learning how to effectively deal with such cases. Only a small proportion, 16%, of dental students reported experiencing incidents of CAN in their clinical practice. In general, there were statistically significant differences between preclinical and clinical students, but there were no significant differences in awareness between female and male students when the source of information and role in dealing with CAN were taken into consideration. Both preclinical and clinical dental students were aware of CAN, although there were concerns about their ability to cope with it. The results emphasize the importance of comprehensive education and training programs across the dental curriculum about CAN.

RESUMO

The potential to generate variable pore sizes, simplistic surface modification, and a breadth of commercial uses in the fields of biosensors, actuators, drug loading and release, and the development of catalysts have unquestionably accelerated the usage of nanoporous gold (NPG)-based nanomaterials in research and development. This article describes the process of the generation of hierarchical bimodal nanoporous gold (hb-NPG) by employing a step-wise procedure involving electrochemical alloying, chemical dealloying techniques, and annealing to create both macro- and mesopores. This is done to improve the utility of NPG by creating a bicontinuous solid/void morphology. The area available for surface modification is enhanced by smaller pores, while molecular transport benefits from the network of larger pores. The bimodal architecture, which is the result of a series of fabrication steps, is visualized using scanning electron microscopy (SEM) as a network of pores that are less than 100 nm in size and connected by ligaments to larger pores that are several hundred nanometers in size. The electrochemically active surface area of the hb-NPG is assessed using cyclic voltammetry (CV), with a focus on the critical roles that both dealloying and annealing play in creating the necessary structure. The adsorption of different proteins is measured by solution depletion technique, revealing the better performance of hb-NPG in terms of protein loading. By changing the surface area to volume ratio, the created hb-NPG electrode offers tremendous potential for biosensor development. The manuscript discusses a scalable method to create hb-NPG surface structures, as they offer a large surface area for the immobilization of small molecules and improved transport pathways for faster reactions.

RESUMO

Introduction The first permanent molars (FPMs) are the first permanent teeth to emerge in the oral cavity, which have an important role in dentition, dental development, and occlusion. FPMs are the most susceptible teeth to caries due to early eruption. There are many adverse consequences related to losing FPMs. Many of the previous studies focused on younger age groups. To the best of our knowledge, there needs to be more newly updated data reported in the literature regarding the status of FPMs in adults in Saudi Arabia. The study aimed to assess the status of permanent first molars among adults in a sample of patients in Riyadh. Methods A cross-sectional retrospective study was conducted from the records of patients in the Dental University Hospital, College of Dentistry, King Saud University (KSU), after obtaining ethical approval. Panoramic images of 810 patients ages 18 and above who were seen at KSU, College of Dentistry, were examined to assess the status of FPMs. A panoramic examination was undertaken for various dental reasons in the time between the years 2017 and 2022. Patients were divided into three age groups: 18-30, 31-50, and >50 years. Data were collected in a particular form and analyzed. The prevalence of missing teeth, as well as restored and carious teeth, were recorded. In addition, further information regarding the type of restoration was recorded. Correlations of the findings regarding age, gender, side, and jaw were determined for all cases and were performed using the chi-square test. P-values less than 0.05 were considered statistically significant. Results A total of 810 patients' panoramic radiographs were studied. Panoramic male study subjects were 382 (47.2%), and females were 427 (52.8%). Three-hundred thirty-nine (339; 41.9%) of them were of less than 30 years of age, 327 (40.4%) were in the age group of 31-50 years, and the remaining 144 (17.8%) were above 50 years of age. The prevalence of missing first molar teeth was 145 (17.9%) for teeth 16, 147 (18.1%) for teeth 26, 207 (25.5%) for teeth 36, and 188 (23.2%) for teeth 46. No statistically significant association was found between the age groups and gender and the first molar missing teeth (p=0.848 & p=0.159). Nineteen point thirteen percent (19.13%) of patients had only one missing FPM, 12.3% of patients had two, and 6.29% of them had three missing FPM teeth. Five point fifty-five percent (5.55%) of patients had four missing FPMs. A total of 56.8% (242) radiographs in the overall sample did not show any missing teeth. The mandibular FPMs (35.2%) were found missing more frequently than their maxillary counterparts (14.8%), and the left mandibular quadrant showed a slightly higher rate of missing FPM (25.55%). Statistically, a significant association was seen between the number of missing FPM among different age groups, p-value <0.0001. The most restored, carious, and replaced tooth was the mandibular left molar, and tooth-color restoration was the most commonly used restoration. Conclusion A high prevalence rate of missing first permanent molars (FPMs) was found in this study population. This calls for more awareness and preventive measures to preserve such significant teeth, therefore reducing the need for complex procedures. Further prospective studies on a larger population are needed to comprehensively evaluate the status of FPMs.

RESUMO

Objective: To evaluate the patient's willingness to declare their medical history to their dentists against demographic and medical information. Methods: A self-administered structured questionnaire regarding common chronic condition and pregnancy awareness and attitude toward medical information disclosure to their dentists was designed employing a five-point Likert-type scale. The questionnaire was distributed to among sample of adults. Data were collected and statistically analyzed using descriptive statistics, t-tests, ANOVA, and P values. Results: A total of 573 questionnaires were completed. Only 61.3% were willing to share their medical history with the dentist and 76.1% will disclose previous complications of their condition in the dental office. Two third 71.9%of the sample will disclose about medications and 76.1% will disclose pregnancy month. There was lack of education regarding health conditions, 73.3% did not receive any information about their medications. While 72.8% did not receive any information regarding complications of their disease and 76.3% were not told what to do if complication arises. Conclusion: The population's willingness to reveal their medical information in the dental office is crucial. Though was within acceptable limit but still deficient. Age, education, occupation and marital status have a significant effect on disclosing and awareness. Educating patients and raising their awareness may aid in reducing emergencies, errors, and legal issues in the dental office.

RESUMO

Background: Efforts to evaluate physicians' awareness and attitude toward dentists' comprehensive role in OSA management are relatively negligible. Therefore, this study aimed to assess physicians' awareness and attitude toward the role of dentists in OSA management in Saudi Arabia. Methods: In a multi-center cross-sectional study, a total of 358 physicians in Saudi Arabia were subjected to an e-questionnaire composed of three sections: (1) physicians' demographic data, (2) physicians' general and specific knowledge of OSA and its management [using 29 factual statements to be responded by "True, False, or I don't know" responses], and (3) physicians' attitude towards dentists' role in OSA management [using 12 attitude statements to be responded by a Likert scale of "Never, Rarely, Sometimes, Usually, Always" responses]. A scoring system was applied for both knowledge and attitude, total and percentage mean scores (PMS) were calculated, and knowledge and attitude levels were categorized accordingly. Predictors of correct knowledge and favorable attitude were identified using multiple regression analyses. Results: Physicians had an overall average knowledge level (PMS = 56% ± 19.4%), with 35.5% and 5.9% reporting good general and specific knowledge levels, respectively (χ2 = 143.0, p < 0.001). Physicians had an overall neutral attitude level (PMS = 64.4% ± 17.5%), with about one-half reporting a neutral attitude level (48.9%) and only one-fourth reporting a positive attitude level (27.7%). Higher levels of knowledge were a significant predictor of favorable attitudes (t = 5.71, p < 0.001). Higher training levels were a significant predictor of correct knowledge (t = 3.60, p < 0.001) and favorable attitude (t = 3.15, p = 0.002). Conclusions: Physicians showed insufficient knowledge about OSA and a less than favorable attitude towards dentists' role in its management. Enhancing medical curricula and clinical protocols and guidelines on the dentists' role in OSA management is recommended.
