Oral Hygiene, Oral Health

This randomized controlled trial aims to evaluate the effectiveness and implementation of a Just-in-Time Digital Learning Platform designed to improve teachers' oral health literacy and support the delivery of oral health education in schools. Teachers play an important role in promoting healthy behaviors among children, but many have limited access to structured oral health training. Digital microlearning approaches may provide a scalable and cost-effective solution for strengthening teacher capacity in school-based oral health promotion. Teachers assigned to the intervention group will receive access to a digital learning platform that delivers short, interactive, and evidence-based oral health training modules through mobile devices. The platform will provide educational content, reminders, quizzes, feedback, and progress monitoring. Teachers in the control group will receive standard information or routine training practices. The study will assess changes in teachers' oral health literacy, knowledge, attitudes, and confidence in delivering oral health education. It will also evaluate implementation outcomes, including acceptability, feasibility, adoption, fidelity, reach, and engagement with the digital platform. In addition, the study will examine whether improvements in teacher training lead to better oral health knowledge, behaviors, and clinical oral health outcomes among students.

In Bangladesh, over 95% of pregnant women suffer from gum disease (gingivitis or periodontitis), yet oral health is rarely included in standard pregnancy check-ups. This study tests a new "Integrated Oral Health Promotion Package" to see if teaching oral hygiene during routine prenatal visits can improve the health of mothers. Pregnant women (ages 18-45) will be divided into two groups. The intervention group will receive two face-to-face education sessions with a dental assistant, learn a specific tooth-brushing technique, and receive weekly SMS text reminders to brush their teeth. The control group will receive the standard pregnancy care currently offered in Bangladesh. Researchers will track the participants for 12 weeks to see if the education and reminders lead to better brushing habits (twice-daily) and cleaner teeth and gums compared to the standard care group.

The goal of this observational study is to evaluate and compare a 3D intraoral scanner-based, computer-assisted approach for assessing dental biofilm/plaque accumulation on natural teeth and restorative surfaces with a conventional clinical plaque index (Turesky modified Quigley-Hein Plaque Index, TMQHPI) in systemically healthy adults. The main questions it aims to answer are: * How well does the plaque-covered surface measurement derived from 3D intraoral scanner data agree with TMQHPI scores after plaque disclosure? * How sensitively do the two methods detect changes in plaque levels after supervised toothbrushing? * Do plaque accumulation patterns differ between natural tooth surfaces and restorative materials (direct composite restorations and indirect ceramic veneers), and where are plaque-retentive areas most frequently located? Participants (≥18 years) will receive routine professional mechanical plaque removal as part of standard clinical care. They will then be asked to avoid mechanical and/or chemical plaque control for 4 days. At the follow-up visit, participants will undergo: 1. An intraoral scan and standardized photographs of the full dental arch, 2. Plaque disclosure followed by repeat scanning/photography and TMQHPI scoring by a periodontist, 3. Supervised toothbrushing using the modified Bass technique for 2 minutes, followed by a final scan and photographs. Digital models will be used to quantify plaque-covered surface measures and to generate 3D maps of plaque-retentive areas.

The goal of this study is to learn if educational videos sent through WhatsApp can improve dental health knowledge, healthy habits, and attitudes in primary school children aged 10 to 12 years in Cairo, Egypt. The main questions it aims to answer are: * Do children who receive dental health videos through WhatsApp have better knowledge about caring for their teeth after 8 weeks compared to children who do not receive the videos? * Do children who watch the videos brush their teeth more often and correctly, and make healthier food choices? * Do children who watch the videos feel more positive about taking care of their teeth and visiting the dentist? Researchers will compare children in Grade 5 who receive 6 short dental health videos through WhatsApp (one video per week for 6 weeks) to children in Grade 6 who continue their normal school activities to see if the videos lead to better knowledge, healthy habits, and more positive attitudes about dental health. Participants will: * Answer questions about their dental health knowledge, tooth brushing and eating habits, and feelings about dental care at the start of the study (takes about 15 to 20 minutes in a private room at school) * Children in Grade 5 will join a WhatsApp group and receive one short video (2 to 5 minutes) each week for 6 weeks about topics like why teeth are important, how to brush teeth correctly, which foods are goo

The goal of the ORACLE study is to evaluate the impact of implementing a standardized oral hygiene bundle on outcomes in critically ill, mechanically ventilated patients. The primary objective is to determine whether this bundle can increase the number of ventilator-free days compared to the standard of care.

This randomized controlled trial aims to evaluate the effectiveness of artificial intelligence-generated WhatsApp reminders on improving oral hygiene practices among individuals aged 20-40 years visiting the periodontal clinic at El-Qasr El-Ainy Dental Hospital. Participants will be randomly assigned to either receive health education followed by AI-generated WhatsApp reminders over a 3-month period or to a control group receiving health education only. The primary outcome is the presence of white spot lesions, assessed using the modified Gorelick White Spot Lesion (WSL) index. Secondary outcomes include the presence of dental plaque, measured by the Plaque Index (PI). This study seeks to determine whether AI-generated reminders can enhance oral hygiene adherence compared to standard health education alone.
