Effectiveness of Educational Videos Comparing Single Versus Multiple Topics: A Cluster Randomized Controlled Trial.

Background Dental caries and gingivitis are preventable diseases that remain highly prevalent among children globally and, while transmissible through the transfer of oral bacteria typically from mother to child, differ from communicable diseases that are spread through direct contact, air, or vectors. Unlike communicable diseases, dental caries and gingivitis can be effectively prevented through proper oral hygiene practices and dietary modifications. Oral health education (OHE) intends to improve oral hygiene practices and reduce oral health problems. However, evidence of the impact of multiple topics in OHE on preschool children is lacking. This study aimed to examine the effects of single- versus multiple-topic OHE delivered via video presentations on the plaque and gingival status of preschool children. Methods A parallel five-arm cluster randomized controlled trial was conducted on healthy preschool children aged five and six years. Children with chronic illnesses, disabilities, or conditions that could affect their oral health or ability to participate in the OHE intervention were excluded. OHE interventions were given to children from eight of the 10 classes assigned as intervention groups, while two classes served as the control group and received no intervention. The intervention groups received one, two, or three oral health topics using specially developed animation videos, in Malay language: toothbrushing technique (T), toothbrushing technique and the effects of sugar consumption on oral health (TS), toothbrushing technique and pathogenesis of dental caries and gingivitis (TP), and toothbrushing technique, the effects of sugar consumption on oral health, and pathogenesis of dental caries and gingivitis (TSP). Plaque and gingival scores, along with oral health knowledge, attitude, and skills (KAS), were recorded before and after the intervention. The CONSORT guidelines were followed in reporting. The analyses included descriptive statistics, one-way ANOVA, effect sizes, and multivariate analysis of covariance (MANCOVA) at a 5% significance level. Results A total of 160 participants were equally distributed into five groups (n = 32). There were no baseline differences in plaque or gingival scores. All groups showed significantly lower plaque and gingival scores post-intervention (p < 0.05), with effect sizes ranging from -1.1 to -0.7. No changes in oral health (KAS) were observed. The intervention groups had significantly lower plaque and gingival scores compared to the control group (p < 0.05), but no differences were found between them after adjusting for baseline KAS (p > 0.05). Conclusions This study suggests that including multiple topics in OHE programs for preschool children may not necessarily improve oral health outcomes. Simplified OHE may be more advantageous in terms of time, cost, human resources, and organization.

Do nanofillers provide better physicomechanical properties to resin-based pit and fissure sealants? A systematic review.

The purpose of this study was to systematically review the impact of nanofillers on the physicomechanical properties of resin-based pit and fissure sealants (RBS). This review included in vitro studies with full-length English-language articles reporting on the physicomechanical properties of nanofilled RBS until February 2023. PubMed, Web of Sciences, Scopus, and LILACS databases were accessed for literature searches. The review was formulated based on the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines and used the Consolidated Standards of Reporting Trials (CONSORT) guidelines and risk of bias Cochrane tool for quality assessment. The search resulted in 539 papers, of which 22 were eligible to be included in the review. Inorganic, polymeric, core-shell, and composite nanomaterials were used to reinforce the studied RBS. The inherent nature of the nanomaterial used, its morphology, concentration, and volume used were the primary parameters that determined the nanomaterial's success as a filler in RBS. These parameters also influenced their interaction with the resin matrix, which influenced the final physicomechanical properties of RBS. The use of nanofillers that were non-agglomerated and well dispersed in the resin matrix enhanced the physicomechanical properties of RBS.

Pulp Therapy of Primary Dentition; its Relevance despite Insufficient Histological Evidence: A Review.

Pulp treatment in primary dentition is generally divided into vital and non-vital pulp therapies and assists in the preservation of pulpally involved primary teeth in the dental arch until the affected tooth naturally exfoliates. The success of pulp therapies depends on several factors; e.g. proper case selection, accurate diagnosis and good coronal seal. To date, studies on the success and failure rates of pulp treatments are based on clinical signs and symptoms, radiographic findings and histological analysis. However, the clinical and radiographic evidence may not completely portray the true status of the dental pulp. Histological evidence remains the gold standard in the assessment of pulp condition, whether it is in a healthy or adverse state. The aims of the current research were to summarise the treatment outcomes of pulp therapy in primary dentition based on clinical, radiographic and histological criteria, and to support its relevance in the presence of limited histological evidence to measure authentic treatment success. An electronic database search of dental literature from 1990 to 2022 was carried out using the MEDLINE, i.e. PubMed, database. Current dental literature showed that the success rates of primary tooth pulp therapy are high. The obtained results were based largely on clinical and radiographic studies with narrow histological investigations to assess the treatment outcome(s) of pulp therapy in primary dentition. Despite the scarcity of histological evidence, pulp therapies in primary teeth are still practical due to their statistically empirical success compared to their failure. Consequently, pulp therapy of primary dentition is still relevant, and should continue to be indicated as an important treatment option.

Sequencing analysis of exons 5 and 6 in RUNX2 in non-syndromic patients with supernumerary tooth in Kelantan, Malaysia.

OBJECTIVE: The aim of this study is to do a sequencing analysis of RUNX2 in non-syndromic patients with supernumerary tooth. MATERIALS AND METHODS: Fifty-three patients with supernumerary tooth were identified retrospectively from 1,275 radiographic reviews who attended the Hospital Universiti Sains Malaysia (USM) Dental Clinic. Informed consent was obtained from the patients prior to the study. Blood samples were collected from 41 patients and DNA extractions were performed out of which 10 samples were chosen randomly for PCR amplification using designated primers for RUNX2 followed by DNA sequencing analysis. RESULTS: This study involved 28 male patients (68.3%) and 13 female patients (31.7%) with a gender ratio of 2.2:1 and mean age of 15.9 ± 6.2 years. DNA extraction yielded ~ 40 ng/µl of concentrated DNA, and each DNA sample had more than 1500 bp of DNA length. The purity ranged between 1.8 and 2.0. DNA sequencing analysis did not reveal any mutations in exons 5 and 6 of RUNX2. CONCLUSION: This study did not reveal any mutations in exons 5 and 6 of RUNX2 in non-syndromic patients with supernumerary tooth. CLINICAL RELEVANCE: Analysis of mutations in RUNX2 is important to enhance the understanding of tooth development in humans.

The association of smartphone addiction, sleep quality and perceived stress amongst Jordanian dental students.

INTRODUCTION: Smartphone addiction has been associated with sleeping problems and psychological anxiety. However, little is known about the association of smartphone addiction, sleep quality and perceived stress amongst university students particularly in dentistry. This study investigated the association of these variables amongst dental students in a Jordanian dental faculty. MATERIALS AND METHODS: A sample of 420 undergraduate dental students enrolled for academic year 2017/2018 at the Jordan University of Science and Technology participated in this study. They were given a set of self-administered questionnaires which consisted of questions regarding demographic information, characteristics of smartphone use, assessment of smartphone addiction, sleep quality as well as perceived stress. RESULTS: The mean Smartphone Addiction Scale (SAS) score amongst Jordanian dental students was high (109.9 ± 23.8). The correlation between SAS and Global Pittsburg Sleep Quality Index (PSQI) score was significant (r = 0.137, P =0.005) indicating that the higher the smartphone addiction level, the poorer the quality of sleep. Similarly, a significant correlation was found between Perceived Stress Scale-10 (PSS-10) score and Global PSQI score (r = 0.348, P < 0.001) which implied that students who have higher perceived stress experienced poorer sleep quality. Year 3 students (clinical year), smartphone addiction and perceived stress were determinants of sleep quality. CONCLUSIONS: Dental students who have high levels of smartphone addiction or high perceived stress levels experienced poor sleep quality. Identifying smartphone addicts amongst students as well as stressors are imperative measures to allow timely assistance and support in the form of educational campaigns, counselling, psychotherapy and stress management.
