Project Abstract

This study investigates a multi-faceted set of interventions across dentistry to evaluate preventive, therapeutic, and restorative outcomes in diverse populations, integrating clinical trials, in vitro analyses, and digital workflow assessments. The first objective compares the caries-preventive efficacy of glass ionomer cement (GIC) versus composite resin sealants on first permanent molars in school-aged children, focusing on occlusal caries incidence, sealant retention, and secondary caries over a 24-month follow-up. A randomized, controlled, split-mouth design will minimize confounding factors, with standardized etching, placement protocols, and recall intervals, and will assess patient-reported outcomes and sealant longevity under routine masticatory loads. The second objective evaluates 3D-printed implant-guided surgical templates for single-tooth rehabilitation, emphasizing implant placement accuracy, time efficiency, and postoperative comfort. A prospective cohort will compare template-guided surgeries against freehand protocols using post-operative imaging, computer-assisted planning metrics, and patient satisfaction surveys. The third objective examines bioactive glass–based root canal sealers, assessing their impact on dentin bond strength, sealing ability, and resistance to bacterial penetration through push-out and electrochemical tests, complemented by confocal microscopy to visualize sealant penetration into dentinal tubules. The fourth objective explores salivary biomarkers for the early detection of periodontitis via point-of-care testing, evaluating sensitivity, specificity, and correlation with conventional clinical indices in diverse adult populations. The fifth objective compares minimally invasive nonsurgical therapy with ultrasonic activation to conventional scaling for chronic periodontitis, measuring extraction of subgingival pathogens, probing depths, clinical attachment levels, and patient-reported discomfort. The sixth objective conducts a comparative analysis of whitening agents, measuring safety and efficacy of hydrogen peroxide versus carbamide peroxide on enamel microhardness, surface roughness, and color stability using spectrophotometric and nanoindentation techniques. The seventh objective develops and validates a digital workflow for implant prosthodontics, spanning intraoral scanning, digital design, and CAD/CAM fabrication, assessing fit, marginal adaptation, processing time, and patient satisfaction. The eighth objective investigates LED-accelerated photopolymerization effects on cure depth and marginal adaptation of direct posterior composites under controlled curing protocols. The ninth objective analyzes the periodontal impact and microbial shifts associated with orthodontic clear aligners, monitoring gingival parameters, plaque indices, and microbiome changes over treatment duration. The tenth objective evaluates nanohydroxyapatite–based varnishes for remineralization of early white-spot lesions in adolescents, assessing lesion remineralization depth and surface characteristics via microhardness testing and imaging. The eleventh objective assesses diode laser therapy as an adjunct to scaling and root planing in chronic periodontitis, evaluating clinical outcomes and microbial reductions. The twelfth objective investigates palatal rugae patterns as forensic identifiers in individuals with craniofacial anomalies, validating pattern stability over time and against radiographic landmarks. The thirteenth objective examines intracanal medicaments for smear layer removal and bacterial eradication through in vitro and ex vivo models, including scanning electron microscopy and culture assays. The fourteenth objective conducts a longitudinal study on palatal fissure sealing techniques and caries incidence in high-risk pediatric populations, analyzing retention and clinical outcomes. The fifteenth objective compares tooth whitening outcomes using natural remineralizing agents versus conventional chemical bleaches, evaluating enamel integrity and color change over time. Methodologies integrate randomized controlled trials, in vitro assays, ex vivo analyses, imaging-based assessments, microbiological profiling, and digital workflow validation, with robust statistical analyses to determine non-inferiority, superiority, or equivalence across interventions. Ethical approvals, informed consent, and standardized protocols will ensure reproducibility, while cross-disciplinary collaboration will facilitate translation to clinical practice.

Project Overview

What This Project Is About

---

A final-year project that compares different dental sealants, imaging templates, and materials to improve prevention and treatment outcomes in dentistry. It also covers how new methods for detection, whitening, and restoration could work in real clinical settings. Topics range from simple sealants to advanced digital workflows and laser therapies. If you’re new to the field, this gives a broad view of practical questions dentists face daily.
