Clinical Performance of Two HEMA-Free Universal Adhesive Systems

This randomized controlled clinical trial aims to compare the 12-month clinical performance of two HEMA-free universal adhesive systems for restoring anterior cervical carious lesions. Participants will be randomly allocated (1:1) to receive restorations using either a two-bottle HEMA-free universal adhesive (G2-Bond Universal) or a one-bottle HEMA-free universal adhesive (BeautiBond Xtreme), both applied in self-etch mode. The primary outcome is restoration retention, while secondary outcomes include marginal adaptation, marginal discoloration, and postoperative sensitivity, evaluated at baseline (24 hours), 6 months, and 12 months using the modified USPHS criteria.

Glass Ionomer Restorations With SMART Versus Conventional Treatment in Elderly Cancer Patients

This study will evaluate the clinical performance of glass ionomer cervical restorations placed using the Silver-Modified Atraumatic Restorative Technique (SMART) compared with conventional restorative treatment in elderly cancer patients with cervical carious lesions. The trial is a 12-month randomized clinical trial with four parallel arms and a 1:1 allocation ratio. Two SMART arms will receive 38% silver diamine fluoride (SDF) and potassium iodide followed by either high-viscosity glass ionomer cement (HVGIC) or resin-modified glass ionomer cement (RMGIC), while the conventional arms will receive standard tooth preparation followed by HVGIC or RMGIC without SDF. The primary outcome is retention of the restoration, assessed using USPHS criteria. Secondary outcomes include postoperative hypersensitivity, marginal integrity, recurrent caries, average duration of treatment, anatomic form, color match, surface roughness, marginal discoloration, and patient satisfaction (VAS). Patients will be followed at baseline, 3, 6, and 12 months. The study aims to determine whether the minimally invasive SMART approach offers comparable clinical performance to conventional treatment while reducing chair time and discomfort in a medically vulnerable elderly cancer population.

Clinical Evaluation of Self-Adhesive Flowable Giomer With and Without Selective Enamel Etching

This randomized clinical trial is to evaluate the clinical performance of the self-adhesive flowable Giomer with and without selective enamel etching compared to flowable Giomer using standard bonding protocol in class V cavity restorations over a period of 18 months.

18-Month Clinical Evaluation of Self-Adhesive Flowable Giomer Compared to Conventional Flowable Giomer in Carious Cervical Lesions: A Randomized Clinical Trial

The material under investigation will offer the patient a high strength and high durability restoration with the advantage of having anti-bacterial properties.

The Effectiveness RMGI and Giomer, Individually and Combined Anterior Cervical Caries

This study compares the effectiveness of three dental materials for restoring anterior cervical caries in high-risk patients: resin-modified glass ionomer (RMGI), Giomer, and a combination technique where RMGI is veneered with Giomer. The 18-month randomized clinical trial will assess 75 patients (25 per group), primarily evaluating secondary caries formation, with additional measurements of restoration integrity, appearance, and sensitivity at baseline, 6, 12, and 18 months.

Clinical Performance of ARS Containing Universal Adhesives in Carious Cervical Lesions

Evaluation of composite restorations done in carious cervical lesions restored by a conventional universal adhesive in comparison to a universal adhesive that contains and resistant silane coupling agent according to the Modified United States Public Health Service (USPHS) criteria over 18 months.

Clinical Evaluation of Self-Adhesive Bulk-Fill Composite Versus Conventional Nano-hybrid Composite in Cervical Cavities

The aim of this randomized clinical trial is to compare the six months clinical performance of the self-adhesive bulk-fill composite with the conventional nano-hybrid composite in the cervical lesions of teeth in the esthetic zone. In addition, to evaluate patient's satisfaction towards the self-adhesive bulk-fill material and its total operatory time.
