Bridging the Gap: Dental Students' Attitudes toward Persons with Disabilities (PWDs).

BACKGROUND: Persons with disabilities (PWDs) face significant barriers in accessing dental care, resulting in poorer oral health outcomes compared to the general population. To reduce dental healthcare disparities, dental professionals must develop positive attitudes and acquire the necessary skills to treat PWDs effectively. This study aimed to assess the experiences, education, training levels, and attitudes of dental students and interns toward PWDs, and to explore the relationships between their exposure to PWDs, their education/training regarding managing PWDs, and their attitudes toward PWDs. METHODS: Participants were recruited using convenience sampling. From May to June 2023, a pretested, validated online questionnaire (developed based on existing survey instruments and modified to fit the study context) was distributed to 98 eligible dental students and interns at King Faisal University. Descriptive and analytical statistics were used for analysis. RESULTS: The response rate was 88.78%. There was a statistically positive correlation between students' exposure to PWDs and their attitudes (p < 0.05). Statistically significant relationships were found between students' education/training and their attitudes towards educational experiences and instructors (p < 0.01) and interpersonal interactions with PWDs (p < 0.05). No statistically significant relationship existed between the year of study and future encounters with PWDs (p = 0.176). Additionally, 42.5% of students felt inadequately prepared to treat PWDs, and 88.5% expressed a desire for further education. Notably, 20.7% reported no training on PWDs, while 70.1% preferred clinical education. CONCLUSIONS: The study underscores the importance of exposure and training in shaping dental students' attitudes toward PWDs. Dental schools should prioritize structured teaching, greater contact with the disabled community, and hands-on experiences to ensure dental professionals are both well prepared and positively inclined to treat PWDs. These findings have significant implications for improving dental education curricula.

Oral health of individuals with cerebral palsy in Saudi Arabia: A systematic review.

OBJECTIVE: This systematic review aimed to comprehensively summarize and critically assess studies conducted on oral health outcomes among individuals with cerebral palsy (CP) in Saudi Arabia. METHODS: This study followed the Participants, Exposure, Control and Outcomes (PECO) framework to formulate a focused research question. We conducted an extensive literature search across multiple databases, including PubMed, Medline, Scopus and Embase, in addition to clinical trial registers. Inclusion criteria encompassed clinical studies conducted in either English or Arabic, focusing on CP as defined by the International Classification of Diseases 10 (ICD10), and examining various oral health conditions and parameters. Nonclinical studies, commentaries, other systematic reviews and letters to the editor were excluded. Data extraction included comprehensive information about the study characteristics, oral health outcomes (dental, oral or periodontal disease; changes in standardized indices; dental trauma and other types of oral diseases) and an assessment of the risk of bias using the Appraisal Tool for Cross-Sectional Studies (AXIS). RESULTS: The initial search yielded a total of 879 articles, ultimately resulting seven studies that met our stringent inclusion criteria. All of these studies were conducted as cross-sectional investigations in different cities within Saudi Arabia. The sample sizes ranged from 46 to 400 participants, all falling within the age range of 2-18 years. Notably, the prevalence of dental caries among individuals with CP in these studies varied significantly, with rates ranging from 52.9% to as high as 98.6%. Additionally, a substantial portion of CP patients exhibited poor oral hygiene, with figures ranging between 34.6% and 66.2%, and dental trauma was reported in 47.5% of the cases. Moreover, these studies underscored the influence of motor function and intellectual disabilities on the oral health status of CP individuals. Furthermore, various secondary outcomes, including periodontal parameters and oral health-related quality of life, were also assessed. However, it is essential to acknowledge that several sources of bias were identified within these studies, raising questions about the generalisability of their findings. CONCLUSION: In conclusion, the systematic review revealed a concerning pattern of high dental caries prevalence and other oral health issues among individuals with CP in Saudi Arabia. Nevertheless, the need for comparative studies between CP patients and those without CP is evident to establish a definitive understanding of the oral health status of CP individuals. Initiating early interventions such as oral hygiene education, preventive dentistry programs, and orthodontic interventions could potentially contribute to improved oral health outcomes for individuals with CP in Saudi Arabia.

Oral Health Status, Oral Health Behaviors, and Oral Health Care Utilization among Persons with Disabilities in Saudi Arabia.

Various studies have indicated that persons with special needs may face several barriers to dental treatment, which increases the prevalence of oral diseases in this population. Moreover, these studies suggested that Saudis with special needs have a higher prevalence of oral diseases, such as dental caries and periodontal disease. The aim of this review is to synthesize evidence regarding the current status, trends in oral health behaviors, and oral health care utilization among these individuals, as well as to assess the quality of the literature. Furthermore, this review seeks to recommend directions for future research and oral health care policymaking. An electronic search was conducted using the following databases and registers: PubMed/Medline, Embase, ISI Web of Science, Scopus, ClinicalTrials.gov, and CENTRAL. Gray literature, which included conference proceedings and unpublished literature, was searched via the library services and Google/Google Scholar, and the quality of studies was assessed using the AXIS scale for cross-sectional studies. A total of 38 studies were included in this review, with the majority of the studies graded as 'low'. Within the limitations of this study, it can be concluded that individuals with special needs have limited access to oral health care, poor oral health status, and a general lack of awareness in regard to oral health. Therefore, nationwide surveys should be carried out to ascertain the actual extent of the oral inequities among individuals with special needs.

The Impact of Autologous Platelet Concentrates on the Periapical Tissues and Root Development of Replanted Teeth: A Systematic Review.

INTRODUCTION: In many cases, the replanted teeth may undergo resorption or ankyloses. Recent studies show that autologous platelet concentrates (APCs) may improve the outcomes of tooth replantation. The aim of this systematic review was to summarize and critically appraise the currently available literature on the use of APCs before tooth replantation. METHODOLOGY: An electronic search was conducted on the following research databases: PubMed/MEDLINE, ISI Web of Science, EMBASE and Scopus. The following medical subject heading (MeSH) keywords used were: ((tooth replantation) OR (replanted tooth) OR (teeth replantation) OR (replanted teeth)) AND ((autologous platelet concentrate) OR (platelet-rich plasma) OR (platelet-rich fibrin) OR (autologous platelet)). The studies' data was extracted, and the research' quality was rated using the CARE and ARRIVE protocols. RESULTS: Ten case reports and three animal studies, one cell study and one study, which included both animal and in vitro experiments, were included in this review. In majority of the studies, APCs improved the outcomes of tooth replantation. However, there were various sources of bias in the most of the research, which may have influenced the results. CONCLUSIONS: Although majority of the studies indicate that APCs may improve outcomes of tooth replantation, majority of the studies contained numerous sources of bias. Additionally, the sample size of the included subjects is inadequate to predict the clinical efficacy of APCs in management of replanted teeth. Large-scale, multi-center and long-term studies are required to ascertain the efficacy of APCs in improve the outcomes of tooth replantation.

The Top 100 Most Cited Articles Published in Dentistry: 2020 Update.

This bibliometric review is aimed to analyze the top 100 most-cited publications in dentistry and to compare its outcomes. A literature search was performed using Elsevier's Scopus, without any restriction of language, publication year, or study design. Of 336,381 articles, the top 100 were included based on their citation count, which ranged from 638 to 4728 citations (Feijoo et al., 326 to 2050). The most productive decade was the 2000s, with 40 articles on the list (Feijoo et al., 1980s: 26). Marx RE (7%) was the major contributor in this study (Feijoo et al., Socransky SS: 9%), and almost half (48%) of articles were from the USA. Of the top 100 articles, 26% focused on periodontology (Feijoo et al., periodontology: 43%), while 17% of the total were published in the Journal of Dental Research (Feijoo et al., Journal of Clinical Periodontology: 20%). Most of the publications were narrative reviews/expert opinion (36%), (Feijoo et al., case series: 22%), and were within the evidence level V (64%) (Feijoo et al., 54%). The citation count that a paper secures is not necessarily a reflection of research's quality, however, the current analysis provides the latest citation trends in dentistry.

Evaluation of 2% Chlorhexidine and 2% Sodium Fluoride as Endodontic Irrigating Solutions on Root Dentine Microhardness: An In Vitro Study.

OBJECTIVES: The aim of this study was to evaluate the effects of 2% chlorhexidine gluconate (CHG) and 2% sodium fluoride (NaF) as endodontic irrigants on microhardness of root dentin. MATERIALS AND METHODS: In this in vitro study, access cavity and root canal preparations were done on 24 freshly extracted anterior teeth. After sectioning into 24 dentin discs using hard tissue microtome in 2 mm thickness, all samples were immersed in solutions of 17% ethylenediamine tetra-acetic acid (EDTA) (2 minutes) followed by 2.5% of sodium hypochlorite (NaOCl) (10 minutes). Then samples were randomly divided into three groups based on the irrigant used: Group I: saline (control group); Group II: 2% NaF; Group III: 2% CHG for two minutes each. Dentin microhardness was measured before (pretreatment), during (after treatment with 17% EDTA and 2.5% NaOCl), and after the experimental period (after treatment with saline, 2% NaF, and 2% CHG) using a Vickers indenter. Statistical evaluation of the data was done using one-way analysis of variance (ANOVA) and the Student's t-test, and the values are tabulated. RESULTS: Specimens rinsed in 2% CHG showed a significant increase in Vickers hardness number (VHN) values (p < 0.05), as compared with EDTA and NaOCl groups, whereas saline and 2% NaF groups showed no significant difference. CONCLUSIONS: NaF did not show any significant effect on microhardness of the root dentin. CHG as an irrigant was seen to have a strengthening effect on dentin microhardness in comparison to NaOCl and EDTA, which has decreased the strength of root dentin.

Salivary IgA as a Useful Biomarker for Dental Caries in Down's Syndrome Patients: A Systematic Review and Meta-analysis.

The objective of this systematic review and meta-analysis is to critically analyze and summarize studies reporting association of salivary immunoglobulin A (IgA) levels as a biomarker for dental caries in Down syndrome (DS) patients. Using the keywords salivary [All Fields] AND IgA [All Fields] AND ("down syndrome" [MeSH Terms] OR ("down"[All Fields] AND "syndrome" [All Fields]) OR "down syndrome" [All Fields]), an electronic search was conducted via PubMed and Scopus databases by two authors, H. H. and Z. K. independently. Retrieved studies were screened against the predefined exclusion and inclusion criteria. To estimate the risk of bias, quality assessment of included studies was carried using the Newcastle-Ottawa quality assessment scale for observational studies. Primary search resulted in 10 articles from PubMed and 13 articles from Scopus. Ten studies fulfilled the defined selection criteria and evaluated the salivary IgA (sIgA) level in DS patients with dental caries. Five articles were further analyzed in a quantitative synthesis presented in the meta-analysis. Due to a modified lifestyle and compromised oral hygiene in DS patients, understandably, it is still postulated in the literature that the presence of sIgA can have a protective effect on the occurrence of dental caries as compared with healthy counterparts. As indicated by the present meta-analysis, no conclusions can be drawn as to definitively label sIgA as a biomarker for dental caries. Further, well-designed longitudinal clinical studies and translational research are therefore required before the benchmarking of sIgA as a useful biomarker for dental caries in DS patients with preferable molecular insights.

Common misconceptions regarding COVID-19 among health care professionals: an online global cross-sectional survey / Conceptos erróneos comunes sobre COVID-19 entre los profesionales de la salud: una encuesta transversal global en línea

Background: The COVID-19 pandemic has taken the world by storm, with cases continuously increasing by the hour and with a shortage of information regarding the virus available to the general public. Despite the availability of trusted online sources, there are still misconceptions relating to the virus floating around. This study aimed to find out the level of misconceptions among healthcare professionals (HCPs) worldwide about the ensuing COVID-19 pandemic. Materials and Methods: A descriptive cross sectional study was conducted through a global online survey. The self-administered questionnaire was designed and registered at an online website (Kwiksurveys). A total of 652 participants from 35 different countries across the world responded. Statistical analysis was performed using SPSS version 23. Socio-demographic and discipline characteristics were compared with the help of the chi-square test and univariate and multivariate logistic regression to find significant relationships. Results: Among all HCPs, general physicians (61.2%) were the most common respondents. The responses from females (63.3%) almost doubled those of men, and nearly half of the participants were working in private institutes (49.2%). Additionally, the major source of information used by HCPs about COVID-19 was social media (55.4%). Regarding misconception assessment, 71.6% of participants had correct concepts regarding COVID-19. However, 28.4% had incorrect information. Female HCPs were 1.49 times more likely to have correct concepts compared to males (OR=1.49, 95% CI=1.04-2.14). Conclusions: The majority of the HCPs were keeping themselves up-to-date with current information concerning the knowledge, prevention, and hygiene practices of COVID-19 infection. However, some misconceptions are deeply rooted in the mindsets of HCPs worldwide and need to be addressed by the continuous professional development of HCPs. The availability of reliable sources of information on the pandemic should be encouraged, with adequate explanations also available to the general public in simple terms.

Antecedentes: la pandemia de COVID-19 ha asolado al mundo, con casos que aumentan continuamente y con una escasez de información sobre el virus disponible para el público en general. A pesar de la disponibilidad de fuentes confiables en línea, todavía hay conceptos erróneos relacionados con el virus. Este estudio tuvo como objetivo dilucidar el nivel de ideas erróneas entre los profesionales de la salud (PS) en todo el mundo sobre la pandemia de COVID-19. Material y Métodos: Se realizó un estudio descriptivo de corte transversal a través de una encuesta global en línea. El cuestionario autoadministrado fue diseñado y registrado en un sitio web en línea (Kwiksurveys). Respondieron un total de 652 participantes de 35 países. El análisis estadístico se realizó con el programa SPSS versión 23. Las características sociodemográficas y disciplinarias se compararon con la ayuda de la prueba de chi-cuadrado y la regresión logística univariada y multivariada para encontrar relaciones significativas. Resultado: Entre todos los profesionales de la salud, los médicos generales (61,2%) fueron los que más respondieron. Las respuestas de las mujeres (63,3%) casi duplicaron las de los hombres, y casi la mitad de los participantes trabajaban en institutos privados (49,2%). Además, la principal fuente de información utilizada por los profesionales de la salud sobre COVID-19 fueron las redes sociales (55,4%). En cuanto a los conceptos erróneos, el 71,6% de los participantes tenían conceptos correctos con respecto a COVID-19. Sin embargo, el 28.4% poseía información incorrecta. Los profesionales de la salud mujeres tenían 1.49 veces más probabilidades de tener conceptos correctos en comparación con los hombres (OR = 1.49, IC 95% = 1.04 2.14). conclusión: La mayoría de los profesionales de la salud se mantuvieron actualizados con la información actual sobre el conocimiento, la prevención y las prácticas de higiene de la infección por COVID-19. Sin embargo, algunos conceptos erróneos están profundamente arraigados en la mentalidad de los PS en todo el mundo y deben abordarse mediante el continuo desarrollo profesional de los PS. Se debe alentar la disponibilidad de fuentes confiables de información sobre la pandemia, con explicaciones adecuadas también disponibles para el público en general en términos simples.

Human Saliva: Non-Invasive Fluid for Detecting Novel Coronavirus (2019-nCoV).

The breakthrough of novel coronavirus (2019-nCoV) in Wuhan, a city of China, has damaged the status of health and quality of life. In the sequel of this epidemic or contagious disease, the patient experiences fever, chest paint, chills, a rapid heartbeat, breathing difficulties, pneumonia, and kidney failure. It has been suggested that this disease can spread through human-to-human transmission or by super spreading. By the help of the non-invasive fluid "saliva", it is easy to detect the virus. This can help with the comfort of the patient as well as healthcare personnel. Under this perspective, we discuss the epidemic situation of 2019-nCOV and its relationship with human saliva.

Extent of Awareness Regarding Oral Health and Dental Treatment Needs among Individuals with Hearing and Speech Impairments in Saudi Arabia.

OBJECTIVE: This study aims to evaluate the awareness level of the individuals with hearing and speech impairments (deaf and dumb individuals), in relation to their oral health and dental treatment needs. MATERIALS AND METHODS: The approach of stratified randomization method of sampling was used for the selection of participants. About 240 people with hearing and speech impairments (deaf and dumb) were selected from four cities of Saudi Arabia, which includes AlKharj, Riyadh, Dammam and Abha. A questionnaire of two sections was distributed among the participants for collecting data. A simple descriptive analysis was done, and the data were expressed in terms of frequencies and percentages. Microsoft Excel has been used for compilation of data and execution of graphs. Moreover, the questionnaire data were subject to SPSS data analysis (IBM SPSS Statistics for Windows, Version 22.0, Armonk, IBM Corp. NY). RESULTS: Most of the participants were not aware of the importance of oral health. Majority of the participants described that they did not visit qualified dentists in the past and many of them did not know the right way of doing tooth brushing. Hence, deaf and dumb individuals lack basic knowledge about oral health and dental treatment needs. CONCLUSION: The study concluded that the awareness level of oral health and dental treatment needs is low among individuals with hearing and speech impairments (deaf and dumb) in Saudi Arabia.

Oral health knowledge and attitude among caregivers of special needs patients at a Comprehensive Rehabilitation Centre: an analytical study.

AIM: To evaluate knowledge and attitude of caregivers/healthcare workers regarding oral health of special need patients, at a comprehensive rehabilitation centre. MATERIAL AND METHODS: A validated self-administered structured questionnaire was used in an interview style among 120 caregivers at a comprehensive rehabilitation centre. The first part of questionnaire collected demographic information (age, gender, experience, literacy). The other part of the questionnaire was related to the knowledge and attitude of caregivers regarding importance of oral health including oral hygiene practices, cause of tooth decay, significance of fluoride, common oral problems and need for oral health education. Comparison between oral health knowledge and oral health attitude of caregivers was done using one-sample t Test. The level of significance was set as p=0.005*. RESULTS: Adequate oral health knowledge was found to be among 59.2% and favourable attitude of caregivers towards oral health care was found among 48.3%. The results indicate that though majority among caregivers had adequate knowledge but their attitude towards oral health was inadequate. CONCLUSION: Caregivers showed a deficiency in the proper oral health attitude. To improve oral health attitudes of caregivers, dental education plus training programs should be given high priority.

Bactericidal Efficacy of Photodynamic Therapy Against Periodontal Pathogens in Periodontal Disease: A Systematic Review.

OBJECTIVE: The aim of this study was to assess the bactericidal efficacy of antimicrobial photodynamic dynamic therapy (aPDT) as an adjunct to scaling and root planing (SRP) against periodontal pathogens. BACKGROUND DATA: SRP followed by laser therapy has better clinical outcomes than conventional SRP alone. MATERIALS AND METHODS: The question addressed was "Does aPDT as an adjunct to SRP exhibit better bactericidal effect against periodontal pathogens than the use of SRP alone in periodontal disease?" MEDLINE(®)/PubMed, Embase, Scopus, Web of Science, and Google Scholar databases were searched from 1977 to December 2015, using different combinations of key words. Review articles, in vitro and experimental studies, and articles in languages other than English were excluded. RESULTS: Seventeen clinical studies were included. Laser wavelengths and duration of irradiation ranged between 470 and 810 nm and 60 and 300 sec, respectively. All studies showed that aPDT application was effective in reducing the counts of periodontal microbes at follow-up. Four studies showed significantly reduced bacterial counts for aPDT as an adjunct to SRP compared with SRP alone. Thirteen studies showed comparable reduction in the counts of periodontal bacteria when aPDT alone or as an adjunct to SRP was compared with SRP alone. CONCLUSIONS: The bactericidal efficacy of aPDT as an adjunct to SRP against periodontal pathogens in periodontal disease remains debatable.

Efficacy of honey in comparison to topical corticosteroid for treatment of recurrent minor aphthous ulceration: a randomized, blind, controlled, parallel, double-center clinical trial.

BACKGROUND: Recurrent aphthous ulceration represents a very common mucosal disorder that general dentists may encounter on a daily basis, and for which there is no curative treatment. The best treatment that can be achieved is to avoid local traumatic precipitants, lessen the pain and duration of ulceration by suppressing the local immune response, and prevent secondary infection. OBJECTIVE: The objective of this study was to clinically determine the efficacy of honey as a topical treatment of recurrent minor aphthous ulceration in a Saudi cohort. METHOD AND MATERIALS: A randomized, blind, controlled, parallel, double-center clinical trial was carried out. Honey was applied by patients four times a day for 5 days. Clinical parameters (ulcer size, pain scale, and degree of erythema and healing) were recorded both at baseline and during the follow-up period. RESULTS: There were 94 subjects, with 180 minor recurrent aphthous ulcerations. The ulcers were distributed as 67, 57, and 56 ulcers for honey, topical corticosteroid, and Orabase treatment, respectively. There was a statistically significant difference between the honey group and the other two groups in terms of reduction of ulcer size, days of pain, and degree of erythema. No side effects were reported in any group. CONCLUSION: Honey was found to be effective and safe in reducing minor aphthous ulcer pain, size, and erythema in a Saudi cohort.
