Clinical trials

This clinical trial aims to evaluate if nano-hydroxyapatite (Nano-HA) toothpaste effectively treats children with Molar-Incisor Hypomineralization (MIH). It will also assess the safety of Nano-HA toothpaste. The main questions are: * Does Nano-HA toothpaste reduce caries incidence, improve tooth aesthetics, and decrease hypersensitivity? * How does Nano-HA compare to fluoridated toothpaste in terms of outcomes? Participants will: * Use Nano-HA or fluoridated toothpaste daily for 12 months. * Visit the clinic for checkups and evaluations every 1 to 3 months. * Record symptoms, brushing compliance, and sensitivity. The study will compare Nano-HA toothpaste to fluoridated toothpaste to determine its efficacy in managing MIH .

This study will be conducted at King Abdulaziz University Dental Hospital (KAUDH). Ethical approval was obtained from the Research Ethics Committee of the Faculty of Dentistry at King Abdulaziz University (32-03-25). Inclusion criteria will include healthy and cooperative children aged 4 to 12 years who are referred to the radiology department for two-bitewing radiographs. Children with a history of epilepsy or anxiety disorder will be excluded. The study's purpose, risks, benefits, and limitations will be explained to the parents or guardians of eligible children by trained dental interns. Those who agree to participate will be asked to sign an Arabic consent form before their involvement. Additionally, an assent form will be obtained from children aged seven and older. Subjects' age, gender, previous dental experience, and behavior during previous dental visits, as assessed by Frankl's behavior rating scale , will be recorded, along with whether they own or have prior exposure to a virtual reality device. Only children with cooperative and definitely cooperative behavior will be included. A randomization sequence with an allocation ratio of 1:1 will be generated using computer software and kept with a radiology assistant who is not involved in the study to ensure allocation concealment. Due to the nature of the study, neither the subject nor the radiologist will be blinded to the group allocation. However, the statistician will be blinded to which group each subject will be allocated. Before taking the radiographs, subjects will be asked to select a video from a list of popular cartoon shows or a video of their preference. In the test group, the subjects will wear virtual reality device goggles (LG 360 virtual reality \[VR\] headset, LG Electronics) connected to a mobile phone, and the chosen video will be played. In the control group, radiographs will be taken without the use of any distraction device. The sounds of the videos will be played on headphones. All bitewing radiographs will be taken by the same radiologist, following the As Low As Reasonably Achievable (ALARA) protocol and hospital guidelines. The procedure uses either size one or size two bitewing Photostimulable Phosphor digital sensors, along with a film holder and a rectangular collimator. While taking the radiographs, the Tell-Show-Do behavior management technique will be used with all participating children, and they will be recorded with a high-resolution camera. The camera will aim toward the face and the body. Later, two trained and calibrated evaluators will independently assess the participating children's behavioral pain using the face, legs, activity, cry, and consolability (FLACC) behavioral pain assessment scale. The FLACC scale ranges from 0 to 10, with 0 indicating no pain and 10 the worst possible pain. Additionally, the behavior during the BWS will also be recorded using Frankl's behavior rating scale classification. Training and calibration for the evaluators will involve watching videos of 20 randomly selected children during their dental treatment. A stopwatch will be used to measure the chair time required to take the radiographs. In the test group, the time needed to place the VR device will be included. Immediately after taking the BWS, the subjects will be shown the Arabic version of the Wong-Baker FACES pain rating scale. They will be asked to select the face that best describes their feelings during the procedure. Finally, the satisfaction with the use of VR during BWS taking will be assessed using a five-point Likert scale, where zero indicates 'not satisfied at all' and 10 means' very satisfied'. Subjects who require repeating any of the BWS will be excluded from the study

This split-mouth randomized clinical trial will be conducted at the Department of Pediatric Dentistry, King Abdulaziz University Dental Hospital (KAAUDH). The inclusion criteria will include healthy, non-anxious, cooperative children aged six to 12 who require non-urgent dental treatment involving at least one pair of contralateral maxillary molars needing buccal infiltration anesthesia with no previous dental history or experience. The children will be screened for eligibility, and a single trained dental intern will approach the parents or guardians of eligible children. Those who agree to be screened for participation in the study will be asked to sign an Arabic consent form. Before the scheduled screening appointment, children's anxiety levels will be assessed using a high score on the Abeer Children Dental Anxiety Scale (ACDAS) in the waiting area. During the appointment, a single trained dental intern will perform the dental examination and prophylaxis, while two trained and calibrated dental interns will assess children's behavior using the Frankl Behavior Rating Scale. Children found to be non-anxious based on their ACDAS score and cooperative or definitely cooperative based on the Frankl Behavior Rating Scale will be considered eligible for the study. Two treatment appointments will be scheduled for them, and consent and assent forms for participation in the study will be obtained. Computer randomization will be performed to determine the treatment sequence (DentalVibe intraoral vibration device followed by Buzzy Bee® extraoral vibration device, or vice versa) and the site (right or left). Randomization will be performed before the first scheduled treatment appointment. The subjects will be seated in the dental chair for five minutes to acclimate to the environment. To measure the physiological changes of the participating subjects, a pulse oximeter device (OxyWatch, ChoiceMMed, Hamburg, Germany) will be applied, and a trained dental intern will record the baseline heart rate (HR). During the treatment, HR will also be recorded. The tip of the DentalVibe intraoral vibration device will be gently placed on the mucobuccal fold above the tooth to be anesthetized. In contrast, the Buzzy Bee® extraoral vibration device will be positioned externally above the buccal infiltration site. During maxillary buccal infiltration, all subjects will be videotaped using a high-resolution camera, focusing on the face and body. Later, two trained and calibrated evaluators will independently assess the child's behavior during the procedure using the Face, Legs, Activity, Cry, Consolability Scale (FLACC) Immediately after administering anesthesia, the subjects will be positioned upright, and the same trained dental intern will introduce the face version of the Visual Analogue Scale (VAS). Finally, after completing both procedures, the subjects will be asked about their future preference for the vibration device. Due to the study's design, both the investigator administering the maxillary buccal infiltration and the subjects will not be aware of which group they belong to.

Molar-Incisor Hypo mineralization (MIH) was first described in 2001 as a developmental enamel defect . It is a condition in which the enamel of at least one first primary molar is affected with a qualitative defect causing abnormal translucency appearing as demarcated opacities; The permanent incisors and second primary molars can also be affected . MIH has adverse consequences on the oral health and child's quality of life. It increases the risk of caries, discomfort and teeth sensitivity . MIH management comprises a variety of treatment options ranging from total caries removal to the polar opposite treatment option of no caries removal and non-invasive methods used to prevent caries progression . Dental caries prediction and prevention are now more important than dental caries diagnosis and treatment. Recently, the reasons for repairing dental cavities have been narrowed, and caries prevention is being used to reduce caries . Salvadora persica, commonly known as Miswak was used as a toothbrush for many years among many countries . It was reported to have a significant effect on oral health and caries prevention .Other studies have found a consistent link between the use of Miswak and a reduction in oral bacteria. However, a comprehensive assessment of using Miswak in the treatment and control of MIH among young children has yet to be conducted. Therefore, the aim of this clinical trial is to assess the effect of SalvadoraPersica and fluoridated toothpaste on controlling hypersensitivity and preventing caries among children with MIH in primary schools. Additionally, this trial will evaluate the shade of the hypo-mineralized enamel before and after using SalvadoraPersica and fluoridated toothpaste

This study aims to evaluate the effect of water floss in reversing peri- implant mucositis around dental implants

This study is a randomized controlled clinical trial with a split-mouth design to evaluate the effect of Advanced Platelet-Rich Fibrin (A-PRF) application on socket healing following dental extractions in smokers. In the split-mouth design, each participant serves as their own control, minimizing inter-subject variability and controlling for potential confounders such as smoking habits, oral hygiene, and systemic health conditions. Bilateral tooth extractions will be performed for each participant, with one extraction site randomly assigned to receive socket preservation using an A-PRF plug, while the contralateral site will be left to heal naturally without intervention. The study will be conducted at the Faculty of Dentistry and the University Dental Hospital, King Abdulaziz University, Jeddah, Saudi Arabia. Recruitment began in December 2025 and will continue until the targeted sample size is achieved.

The goal of this clinical trial is to test if children aged between 6 and 14 years who are receiving a dental injection will feel less pain by using a vibration device applied to the injection site during the injection compared to vibrating the lip using only the researcher's hands without using the vibration device. It will also test if this device makes them feel less anxious during the injection. The main question it aims to answer is: Does using the Vibrasthetic device make dental injections more comfortable for children? Researchers will compare the effect of using this vibration device versus using their hands for manual vibration of the lip in the same child. Participants will: * Experience one method of vibration during their visit to the dentist (either the vibration device or manual vibration). * then after 2 weeks they will go to the same dentist again and experience the other method of vibration. * Receive the dental treatment they need in both visits. Participants will be asked to rate the pain they felt after the injection. This will be done by the participants choosing one of 6 pictures we will show them. Each picture explains the level of the pain they felt, and each picture has a score. We will score the pain the participants felt by looking at which picture they chose to describe their pain from the injection.

The goal of this clinical trial is to learn whether using three dimensional (3D)-printed anatomical models improves the informed consent process for participants undergoing orthognathic surgery. The trial also explores how these models affect participants understanding, anxiety, satisfaction, and communication with the surgeon. The main questions it aims to answer are: * Do 3D-printed anatomical models improve participants understanding of their jaw condition and the surgical procedure? * Do they reduce participants anxiety before surgery? * Do they enhance overall participants satisfaction and the physician-patient relationship? Researchers compares participants who received standard two dimensional (2D) imaging and verbal explanations with those who received the same information plus 3D-printed jaw models. Participants: * Scheduled for double- or triple-jaw orthognathic surgery * Randomly assigned to receive either traditional 2D education or the 3D-printed model intervention * Complete a validated questionnaires assessing understanding, anxiety, satisfaction, and doctor-patient communication

Title of Study: Assessment of the Impact of Art-Based Pain Assessment Tool on Pain Communication, Joint Function, and Anxiety in Patients with Temporomandibular Disorders (TMD): A Randomized Controlled Trial Location: King Abdulaziz University Dental Hospital (KAUFD), Jeddah, Saudi Arabia What Is This Study About? This study examines how an art-based tool can help improve communication and understanding of pain among patients with jaw joint disorders (TMD). It compares two groups: * Standard care: Routine diagnostic and therapeutic procedures * Intervention: Standard care plus a guided art-based tool using paintings to express and discuss the TMD experiences What Is the Art-Based Tool? This novel method, called the Artistic Pain Exploration (APE), uses paintings to help patients describe their pain that relates to TMD and its effect on their quality of life: 1. Participants will be shown three paintings (e.g., The Scream by Edvard Munch) 2. Participants will choose the one that best resonates with them 3. A guided discussion follows, exploring how the image relates to their physical and emotional pain as well as the effect of pain on their daily activities Research Questions: 1. Does using the APE method help participants better communicate and understand their pain? 2. Does it improve jaw function and reduce anxiety more than standard assessment? Who Can Participate? Participants may be eligible if they: * Are 18 years or older * Have early-stage TMD (not needing surgery) * Can give informed consent Participants cannot participate if they: * Require jaw surgery * Have severe mental illness (e.g., psychosis or bipolar disorder) * Take narcotic pain medications regularly What Will Happen During the Study? * Participants are randomly assigned to one of the two groups. * Each participant will complete a standardized questionnaire before and after two weeks to assess the level of anxiety. * All participants will be screened for depression via a standardized questionnaire before the first visit. * All will undergo a clinical exam to assess the TMJ pain and function and receive appropriate medications and lifestyle instructions. * Some participants (intervention group) will also discuss their pain using the artwork. * All participants will be seen for a follow up in 2 weeks to assess the TMJ function and pain. Potential Risks and Discomforts Participants may experience: * Emotional discomfort while discussing pain * Mild anxiety during interviews or questionnaires If needed, a psychiatrist on the research team will provide support or referrals. Potential Benefits * A better understanding of pain * Improved communication with care provider * Possible improvement in pain and jaw function Costs There are no costs to participate.

What is the antimicrobial effect of silver diamine fluoride in oral microbial inhabitants? Researchers will compare silver diamine fluoride (SDF)only and silver diamine fluoride+ potassium iodide(SDF+KI) to see which materials substantially affect on dental caries and oral microbial inhabitants Participants/Parent will: The parent will fill out a comprehensive data sheet for the child (childhood and current dental and medical history) Visit the dental clinic to Receive one of 2 (SDF or SDF+KI) treatment applications once Visit the clinic a 2nd time for a 2-4 week Treatment Follow-up Go through the sample collection process twice( pre- and 2-4 weeks post- Treatment) Sample collection including (Saliva- Biofilm and caries tissue sample)

The frequency of oxygen desaturation during emergency intubation is not uncommon. However, the significance and clinical sequalae of hypoxia during emergency intubation in critically ill, non-trauma patients is not known. Therefore, the aim of this study is to evaluate neurologic function post-intubation of critically ill, non-trauma patients. Providing knowledge on whether the degree of hypoxia during emergency intubation is associated with worse neurologic outcomes, will guide clinical practice to ameliorate that level of hypoxia
