Effectiveness of Personalized Digital Oral Health Intervention in Patients With Fixed Orthodontic Appliances.
This study will evaluate whether personalized digital oral-health education delivered through WhatsApp messages can improve oral hygiene in patients aged 16-25 years who wear fixed orthodontic appliances (braces). A total of 66 participants will be assigned to two groups. The intervention group will receive weekly digital oral-health messages for 12 weeks, while the control group will receive conventional verbal oral-hygiene instructions. Both groups will receive the same antibacterial mouthwash. Oral hygiene will be assessed at the beginning of the study and after 12 weeks by measuring plaque and gingival health using the Plaque Index and Gingival Index. The findings will help determine whether digital education can support conventional oral-hygiene instructions for patients undergoing orthodontic treatment.

Comparison of Model-Based and Video-Based Toothbrushing Instruction in Children
Good toothbrushing is important for keeping children's teeth healthy. Dentists commonly teach children how to brush their teeth using dental models or instructional videos. However, it is not clear whether one method helps children clean their teeth more effectively than the other. The purpose of this study was to compare face-to-face toothbrushing instruction using a dental model with video-based instruction in children aged 7 to 9 years. Children were randomly assigned to one of two groups. One group watched a video showing how to brush teeth using a dental model, while the other group received a face-to-face demonstration using the same model and toothbrushing technique. After instruction, a plaque-disclosing tablet was used to make dental plaque visible on the children's teeth. Photographs were taken before and after the children brushed their teeth for two minutes. The researchers then compared how much plaque was removed in each group. The main question was whether the two teaching methods differed in helping children remove dental plaque immediately after instruction.

Essential Oil Mouthwash - Oral Hygiene
Background Inadequate oral health can further compromise general health, particularly in elderly patients who are more susceptible to tooth loss, periodontal disease, and oral infections. These conditions can impair nutrition and overall well-being and are associated with increased risks of systemic diseases, underscoring the critical need for effective oral care in this population. Essential oils and various plant extracts have attracted considerable attention as potential natural medicinal products due to their proven antibacterial, antifungal, antiviral, and antioxidant properties. However, the precise effects and underlying mechanisms through which essential oil mouthwashes promote oral health remain incompletely understood. Objective This study aims to evaluate the potential of a mouthwash formulated with a blend of tea tree, lemon, and bay laurel essential oils, which have long been recognized for their medicinal properties in alleviating inflammatory signs of intraoral mucosa and promoting both oral and gingival health, in comparison with/ without alcohol-based mouthwashes. Methods One hundred five community-dwelling elderly individuals were randomly assigned to one of three groups and used a designated mouthwash for oral care over 21 days. The study groups were as follows: 1. Essential oils mouthwash (tea tree, lemon, and bay laurel). 2. Chlorhexidine alcohol-free mouthwash. 3. Povidone-iodine alcohol-free mouthwash. Participants were instructed to use the assigned mouthwash for oral hygiene at least twice daily, in the morning and evening. Saliva samples were collected on day 1 (before using the mouthwash) and on day 21 to analyze oral microbiota and inflammation markers and assess oral health and the incidence of upper respiratory tract infections. Expected Results The treatment group of community-dwelling elderly individuals using the essential oil mouthwash is expected to show a significant reduction in oral bacterial load, improvement in gingival inflammation and periodontal symptoms, and a decreased risk of upper respiratory infections compared to the control groups using alcohol-free mouthwashes.

Comparision of Enzymatic and Active Salt Toothpaste
Dental plaque is a major etiological factor in the development of gingivitis. Mechanical plaque control through toothbrushing is essential for maintaining oral hygiene, while toothpaste formulations containing active ingredients may provide additional benefits in controlling plaque accumulation and gingival inflammation. Enzymatic toothpaste containing the lactoperoxidase system and salt-containing toothpaste incorporating sodium chloride and sodium bicarbonate have been investigated for their potential effects on plaque control and gingival health. This randomized, prospective, double-blind, parallel-group clinical study evaluated and compared the efficacy of enzymatic toothpaste, active salt toothpaste, and standard fluoridated toothpaste in reducing dental plaque and gingival inflammation following non-surgical periodontal therapy (NSPT). The study was conducted in the Department of Periodontology, Uttar Pradesh University of Medical Sciences, Saifai, Etawah, Uttar Pradesh, India, from July 2021 to December 2022. The study protocol received approval from the Institutional Ethics Committee of Uttar Pradesh University of Medical Sciences (approval number: 222/2020-21). Written informed consent was obtained from all participants before study procedures. A total of 93 eligible participants with mild to moderate gingivitis were enrolled and randomly allocated to three groups. All participants initially received non-surgical periodontal therapy and used standard fluoridated toothpaste for a four-week pretreatment period. Following the pretreatment period, baseline clinical assessments were performed, and participants received the toothpaste assigned to the respective study group. Group I received enzymatic toothpaste (Curaprox Enzycal 950), containing amyloglucosidase, glucose oxidase, lactoperoxidase, and potassium thiocyanate. Group II received active salt toothpaste (Colgate Active Salt), containing sodium chloride and sodium bicarbonate. Group III received standard fluoridated toothpaste (Colgate Strong Teeth), containing calcium carbonate and sodium monofluorophosphate. Participants were instructed to brush their teeth for two minutes twice daily using the allocated toothpaste for 12 weeks. The use of mouthwashes, interdental aids, and other antiplaque products was restricted during the pretreatment and intervention periods. Clinical assessments were performed at baseline, following the four-week pretreatment period, and after the 12-week intervention period, as specified in the study protocol. The clinical parameters included the Turesky-Gilmore-Glickman modification of the Quigley-Hein Plaque Index (TQHPI), the Gingival Index (GI), and probing pocket depth (PPD). The collected data were analyzed using SPSS software, version 20.0. Within-group and between-group comparisons were performed using appropriate parametric and non-parametric statistical tests. Statistical significance was set at p less than 0.05.

Smartphone App Versus Verbal Motivation for Oral Hygiene in Fixed Orthodontic Patients
This study looked at whether a smartphone app can help patients with fixed braces keep their teeth cleaner than usual spoken advice alone. Fixed braces make plaque harder to remove, which can harm the teeth and gums, so good brushing habits matter. Fifty patients aged 14 to 22 were divided at random into two groups. One group used a purpose-made app ("iTeeth Orthodontics") that sent brushing reminders, timed brushing, and kept a brushing log. The other group received the usual spoken oral-hygiene motivation. Both groups used the same brushes, toothpaste, and rinse, and followed the same cleaning routine. Plaque was measured from photographs at 10 days and at 1, 2, and 3 months, using a computer to calculate how much of each tooth surface was covered by plaque. The two groups were then compared.

Chlorhexidine vs Essential Oil Mouthwash for Plaque Control
Dental plaque is a sticky film of bacteria that forms on teeth and can lead to gum disease if it is not removed regularly. Brushing and flossing help control plaque, but many people also use a mouthwash to help clean areas that are hard to reach. This study compares two common types of mouthwash to see which one works better at reducing plaque: a mouthwash containing chlorhexidine (a medicated antibacterial ingredient) and a mouthwash containing essential oils (natural plant-based ingredients). Both are widely used, but they work in different ways and may cause different side effects. Sixty patients between the ages of 15 and 25 who had gum inflammation (gingivitis) took part. Half of the patients used the chlorhexidine mouthwash twice a day, and the other half used the essential oil mouthwash twice a day, for three months. Researchers measured the amount of plaque on each patient's teeth at the start of the study and again after three months, using a standard scoring method. They also recorded how well patients stuck to the mouthwash routine and any side effects they experienced, such as changes in taste, staining of the teeth, or a burning feeling in the mouth. The goal of this study is to help patients and dental care providers understand the benefits and drawbacks of each mouthwash, so they can choose the option that best fits their needs - whether that is stronger plaque control for a short period of time, or a milder option that may be more comfortable for longer-term use.

Effectiveness of Dental Health Education Methods on Oral Hygiene, Oral Health Care Self-Efficacy and Self-Esteem of Young Orphans
Background: Orphan children are at higher risk of developing oral diseases, compared to non-orphans. They also face various emotional, social, and psychological distresses which affect their general as well as oral health. Aim: To evaluate the effectiveness of three methods of dental health education; namely peer group and game-based health education methods on oral hygiene behavior, oral health care self- efficacy and self-esteem level of a group of institutionalized orphans in Alexandria, Egypt, as compared to conventional health education. Materials and methods: A three-arm randomized controlled clinical trial was compared between peer group based dental health education, game-based dental health education, and conventional dental health education. The study recruited 264 Orphans from non-governmental orphanages in Alexandria, Egypt. Apparently healthy orphans between 7 and 12 years old whose responsible guardians gave consent to allow them to participate in the study will be included. The primary outcome was the improvement in oral hygiene behavior measured by changes in OHI-S and gingival index and the secondary outcome was the change in orphans' self-esteem measured by the Child version of Rosenberg Self-Esteem Scale and the change in orphans' oral health care self-efficacy measured by oral heath behavior self-efficacy questionnaire.
