Correlation Between Posterior Crossbite and Risk of Obstructive Sleep Apnea

This randomized clinical trial aims to evaluate the clinical and radiographic success of NeoPutty MTA compared to formocresol in vital pulpotomy of mandibular primary molars in children aged 4 to 9 years. Participants will be randomly allocated into two groups (1:1) to receive pulpotomy using either NeoPutty MTA or formocresol, followed by restoration with stainless steel crowns. Clinical and radiographic outcomes will be assessed during follow-up visits.

This in vitro study aims to evaluate the accuracy of an Artificial Intelligence (AI)-based automatic design system for fixed dental prosthesis (FDP) compared with conventional computer-aided design (CAD) software. Digital scans of teeth requiring fixed dental prosthesis will be collected and used to generate prosthetic designs using two approaches: human-designed CAD restorations and AI-generated restorations. The primary outcome is design accuracy assessed using 3D superimposition and Intersection over Union (IOU) percentage. Secondary outcomes include margin detection performance measured using F1 score, precision, and recall. A total sample size of 438 scans will be analyzed. The study will determine whether AI-generated prosthesis designs demonstrate comparable accuracy to conventional digital designs.

This randomized controlled clinical trial aims to compare the clinical and radiographic outcomes of Zinc Oxide Eugenol (ZOE) and Iodoform-Calcium Hydroxide (Metapex) as root canal filling materials in primary molars prepared using either rotary or manual instrumentation techniques. Forty-four teeth from children aged 5-8 years indicated for pulpectomy will be randomly allocated into four equal groups based on the combination of instrumentation method and filling material. Clinical parameters-pain, mobility, and sensitivity-will be assessed using standardized scales, while radiographic outcomes, including root resorption and bone density, will be evaluated using Cone Beam Computed Tomography (CBCT) at baseline, 6 months, and 12 months. The study seeks to determine which obturation material and canal preparation technique yield superior healing, adaptation, and resorption compatible with the physiological process of primary tooth exfoliation. Findings are expected to inform evidence-based selection of endodontic materials and instrumentation methods in pediatric dentistry.

This randomized controlled clinical trial aims to evaluate and compare the effectiveness of lavender essential oil and bitter orange essential oil aromatherapy in reducing dental anxiety and pain in children during the administration of local anesthesia. Children aged 6-12 years undergoing dental procedures requiring local anesthetic infiltration will be randomly assigned to lavender aromatherapy, bitter orange aromatherapy, or placebo (empty inhaler). Dental anxiety will be assessed using pulse rate and blood pressure measurements, while pain will be evaluated using the FLACC behavioral pain scale. The findings are expected to provide evidence on the role of aromatherapy as a non-pharmacological, safe, and cost-effective behavior guidance method in pediatric dentistry.

Early childhood caries is a major public health problem affecting preschool children worldwide. Silver Diamine Fluoride is a well-established non-invasive treatment for arresting caries; however, it causes black discoloration of treated lesions. Nano-Silver Fluoride has been introduced as an alternative that may arrest caries without discoloration. This randomized clinical trial aims to compare the efficacy of Silver Diamine Fluoride and Nano-Silver Fluoride in arresting active dentin caries in primary teeth and to assess discoloration, post-operative pain, and parental satisfaction over a 12-month follow-up period.

This randomized, triple-blinded clinical trial aims to evaluate the effect of preemptive analgesia using ibuprofen on pain perception and anxiety during restorative treatment of first permanent molars in children diagnosed with molar-incisor hypomineralization (MIH). MIH-affected teeth often present with hypersensitivity, difficulty in achieving adequate anesthesia, and increased dental anxiety, which complicates dental treatment. Participants aged 6-12 years with MIH will receive either ibuprofen syrup or placebo 30 minutes before treatment. Pain will be assessed using the FLACC Behavioral Pain Scale and Wong-Baker FACES scale, and anxiety will be evaluated through heart rate and oxygen saturation. The results will determine whether preoperative ibuprofen reduces intraoperative pain and improves anxiety control in this population.

This randomized controlled clinical trial aims to compare the effectiveness of virtual reality (VR) eyewear used as a distraction method in combination with the Show-Do (SD) technique versus the traditional Show-Do technique alone in managing dental anxiety and improving behavioral responses among Egyptian children with different levels of hearing impairment during a dental prophylaxis procedure. The study will evaluate dental anxiety using pulse rate and the PJS-Pictorial Scale, while behavior will be assessed using the Frankl Behavior Rating Scale. The trial seeks to provide evidence-based guidance on the implementation of VR technology as an adjunctive non-pharmacological tool for children with communication barriers in pediatric dentistry.

The goal of this (study type: RCT) is to learn if the use of the non-submerged de-epithelized FGG will result in better esthetic outcomes in adults. The main questions that it aims to answer are: * Does this procedure increase the width of keratinized tissue? * Does this procedure increase the depth of the vestibule? Researchers will compare this technique with the gold standard using the FGG to evaluate which technique provides better esthetics.

Despite the benefit of formocresol, there are toxic effects allergic reactions and local soft and hard tissue necrosis have been reported when such formaldehyde compounds were used clinically, however, the adverse effect of the clinically used of this compound are not widely reported. It has been stated that it has a side effect on the permanent successor although it results as a successful technique for the treatment of the primary teeth

Endocrowns are preferred over the post-retained crown, especially at a young age for many reasons; they allow better gingival health and care due to placement of the supragingival margin, have greater fracture resistance limiting the risk for root fracture, thus improving the long-term prognosis of ETMs and has a superior ability to restore ETMs with short crowns, calcified root canals, and thin roots. Furthermore, using CAD/CAM technology facilitates Endocrowns preparation making it simpler with less invasive techniques that can be prepared, fabricated, and cemented in a single visit. The high demand for permanent, esthetic, and conservative restorations has directed clinicians to restore permanent ETMs at a young age with Endo crowns as final coronal restorations. In addition, Biomimetic dentistry leverages modern materials to replicate the biological and mechanical functions of natural teeth, presenting a distinct approach that minimizes the need for extensive tooth reduction and post-placement, particularly advantageous for endodontically treated teeth. Utilizing fiber-reinforced composites, this technique aims to strengthen the dentin-resin bond and evenly distribute occlusal forces across the restoration. By closely adhering to the intact tooth's natural contours and functionality, biomimetic restorations not only preserve more of the natural tooth structure but also reduce stress and strain within the restored tooth. This approach enhances longevity and minimizes the risk of bond failure, with any necessary repairs being straightforward and contributing to the restoration's sustainability. This study explores the application of fiber-reinforced composites within a biomimetic framework for restoring endodontically treated teeth, aiming to achieve durable and biologically compatible outcomes.

Conventional behavior management techniques, namely: verbal communication and tell-show-do were used in the operatory for the participating children (Group A). The children allocated in intervention group (Group B) received a costume-designed storybook explaining the diagnosis and procedures of occlusal composite restoration
