Clinical trials

This clinical study aims to evaluate the effectiveness of patient-specific 3D-printed titanium facial implants in the reconstruction and aesthetic correction of facial defects. The study will include patients presenting with congenital, traumatic, or post-surgical facial deformities requiring reconstructive intervention. Eligible participants will undergo preoperative clinical assessment and radiological imaging to design customized implants using computer-aided design (CAD) and 3D printing technology. The implants will be fabricated from medical-grade titanium and surgically placed according to standardized maxillofacial reconstructive protocols. Postoperative follow-up will assess functional outcomes, implant stability, complication rates, and aesthetic improvement over a defined observation period. Outcome evaluation will include clinical examination and patient-reported satisfaction measures. The objective of this study is to determine whether patient-specific 3D-printed titanium implants provide reliable functional restoration and improved aesthetic outcomes in facial reconstruction compared to conventional reconstructive techniques.

Frontal hyperhidrosis is a form of primary focal hyperhidrosis that significantly impairs patients' quality of life due to excessive visible sweating in the forehead region. Conventional treatment options often show limited efficacy or may be associated with undesirable side effects. This study aims to evaluate the efficacy and safety of intradermal injections of Botulinum Toxin Type A in patients with primary frontal hyperhidrosis. Clinical outcomes will be assessed using Minor's iodine-starch test, the Hyperhidrosis Disease Severity Scale (HDSS), and patient satisfaction scores. Participants will be followed up one month after treatment to evaluate therapeutic response and potential adverse effects.

This randomized clinical study aims to evaluate the efficacy and pain response of two local anesthesia techniques in pediatric dental treatment using an electronic syringe: ligament anesthesia and inferior alveolar nerve block (IANB). The study applies both techniques to the same sample, where each child undergoes pulpectomy for two different teeth, each under the influence of a different anesthesia technique, during two separate visits. This study comes in the context of technological advancements in dentistry, which led to the development of computerized syringes as an alternative to traditional syringes. These devices are characterized by precise control of the anesthetic flow rate, as well as containing musical and auditory systems aimed at distracting the child and reducing feelings of fear and anxiety associated with dental treatment. Additionally, computerized syringes provide audible indicators showing the amount of anesthetic injected and support multiple injection modes such as rapid injection, slow injection, and ligament injection, allowing for more efficient and comfortable anesthetic delivery. Pain intensity will be assessed during three stages of the treatment procedure: during anesthesia administration, during placement of the rubber dam, and during opening of the pulp chambers. Post-procedure pain will also be evaluated using an age-appropriate validated pain scale, along with assessing the satisfaction level of both the children and their parents regarding the use of the electronic syringe as an alternative anesthesia tool. These combined measures aim to provide a comprehensive understanding of the child's experience during dental treatment and contribute to improving anesthesia practices in pediatric dentistry.

TTN is the most common respiratory disorder in the perinatal period, causing 40% of cases of respiratory distress after birth. Lung fluid absorption is initiated by beta-adrenergic agonists, such as endogenous steroids and Catecholamine, which increase during labor. Delayed absorption of fluid from the lungs is thought to be the primary mechanism of transient tachypnea of the newborn (TTN). The accumulation of fluid within the lungs impairs gas exchange, leading to increased respiratory effort. Tachypnea develops to compensate for this, and hypoxemia develops due to impaired alveolar ventilation . The main objective of the study: To study the effectiveness of salbutamol in improving signs of respiratory distress according to the modified Downes score during the first 72 hours of life in infants with transient tachypnea of the newborn (TTN). Secondary objectives: Duration of tachypnea (time to resolution of respiratory distress) Reducing the duration of the need for oxygen support Reducing the length of hospital stay

This clinical trial seeks to investigate a promising new approach to enhance the effectiveness and duration of Botulinum Toxin A (BTX-A) for the treatment of hyperactive masseter muscles. By investigating the role of oral zinc supplementation, this study could provide a cost-effective, sustainable solution for patients suffering from both aesthetic concerns and functional limitations associated with MMH and bruxism. The findings of this study will expand the clinical applications of BTX-A, offering longer-lasting relief and reducing the need for frequent injections, which could revolutionize the management of MMH in clinical practice.

The aim of this study is to compare the clinical and radiographic success of stainless steel crowns placed using the Hall Technique versus the conventional method in the restoration of permanent first molars in children, and to evaluate their effects on occlusal relationships, crown adaptation, and patient satisfaction. Study Outcomes The primary outcome of this study was to evaluate the clinical and radiographic success of stainless steel crowns placed on permanent first molars using the Hall Technique in comparison to the conventional crown placement method. The secondary outcomes included assessment of the marginal fit and adaptation of preformed crowns using both techniques, analysis of changes in occlusal relationships-specifically the vertical dimension of occlusion and overbite-and evaluation of patient satisfaction. Patient satisfaction was measured using a five-point Likert scale at multiple time points: immediately post-treatment, and at one, three, and six months.

Objectives: to compare aesthetic effectiveness of resin infiltration with/without using sodium hypochlorite in managing opacities of MIH on incisors, and to compare parent's satisfaction with results of both application protocols. Methods: Twenty-four teeth with yellow/ brown opacities of MIH, will be diagnosed according to EAPD diagnostic criteria, will be randomly allocated to test or control group. In the test group, the investigators will be applied sodium hypochlorite 5.25% by using cotton wad before treatment, then after the first and second etching cycles (application of the Icon-Etch (ICON® -Etch; DMG, Hamburg, Germany) and Icon-dry (ICON® -Dry; DMG, Hamburg, Germany) according to the manufacturer's recommendations) as irrigation step and following the third -Etch etching cycle Icon-infiltrant (ICON® -Infiltrant; DMG, Hamburg, Germany) will be applied . In control group, the investigators will be applied the same protocol of test group but without using sodium hypochlorite. The masking efficacy will be analyzed using the Lab System to calculate the color difference (ΔE) between the opacity and the adjacent enamel in Adobe Photoshop 2024. The infiltration proportion of opacity will be measured using Image J software and the infiltrated area will be expressed as a percentage. The satisfaction of the parents with the results of both application protocols will be compared using Likert scale.

This clinical research aims to Evaluate Crowns Designed by Artificial Intelligence Versus Crowns Designed by Traditional Design Software The research will be conducted on a sample of patients with an indication for crowning of the first lower molar. Ten dental crowns will be prepared. After obtaining written consent from patients who meet the inclusion and exclusion criteria, 10 dental crowns will be prepared. Measurements will be taken using silicone impressions and then converted into digital format. The digital impression will be sent to the selected dental restoration design software used in the study. The same parameters will be adjusted in all software programs for each crown. After the design is completed, the designs will be sent to the milling unit. For each case, three crowns will be designed and milled from polymethyl methacrylate (PMMA). The crown will be clinically examined and evaluated according to specific criteria. Marginal fit, proximal contact quality, and occlusion will be assessed. The best crown will be milled from zirconia and delivered to the patient.
