Thesis Abstract

Abstract
The quest for whiter and brighter smiles has led to an increasing demand for teeth whitening procedures. This study aimed to assess the efficacy of different whitening agents on dental enamel. The research involved a comprehensive literature review to understand the various whitening agents currently available and their mechanisms of action. A total of 100 participants were recruited for the study, and their teeth were randomly assigned to different whitening agents, including hydrogen peroxide, carbamide peroxide, and charcoal-based products. The methodology included the measurement of baseline tooth shade using a spectrophotometer, application of the whitening agents as per manufacturer instructions, and subsequent shade measurements at regular intervals over a period of four weeks. In addition, enamel microhardness and surface roughness were evaluated before and after the whitening treatments to assess any potential adverse effects on dental enamel. The findings revealed varying degrees of efficacy among the different whitening agents, with hydrogen peroxide demonstrating the most significant improvement in tooth shade. However, this was accompanied by a slight reduction in enamel microhardness, which was not observed with carbamide peroxide or charcoal-based products. Surface roughness analysis showed minimal changes after treatment, indicating the overall safety of the whitening agents on enamel. The study highlighted the importance of considering both the efficacy and safety profiles of whitening agents when determining the most suitable option for patients. The results contribute to the existing body of knowledge on teeth whitening procedures and provide valuable insights for dental practitioners in recommending appropriate whitening agents based on individual patient needs and preferences. In conclusion, this research underscores the significance of evaluating the efficacy of different whitening agents on dental enamel to ensure optimal outcomes while minimizing potential risks. Further studies are warranted to explore long-term effects and patient satisfaction following teeth whitening treatments.

Thesis Overview

The project titled "Assessment of the Efficacy of Different Whitening Agents on Dental Enamel" aims to investigate and compare the effectiveness of various whitening agents on dental enamel. This research project is significant in the field of dentistry as it addresses the growing demand for teeth whitening procedures and the need to understand the impact of different whitening agents on dental health. The research will begin with a comprehensive literature review to explore existing studies on teeth whitening agents and their effects on dental enamel. This review will provide a solid foundation for the research by highlighting key findings, methodologies, and gaps in the current knowledge. The methodology chapter will outline the research design, sample selection criteria, data collection methods, and analysis techniques to be employed in the study. The research will involve conducting experiments on extracted teeth samples using various whitening agents commonly used in dental practice. The enamel changes will be assessed through visual inspection, colorimetry, and scanning electron microscopy to evaluate the efficacy of each whitening agent. The discussion of findings chapter will present and analyze the results obtained from the experiments. The research will compare the effects of different whitening agents on enamel color change, surface texture, and microstructure. The findings will be interpreted in relation to the existing literature and implications for dental practice will be discussed. Finally, the conclusion and summary chapter will summarize the key findings of the research and provide recommendations for future studies and clinical practice. The project will contribute to the understanding of how different whitening agents affect dental enamel and help dentists make informed decisions when recommending teeth whitening treatments to their patients. Overall, the research project "Assessment of the Efficacy of Different Whitening Agents on Dental Enamel" will provide valuable insights into the effects of whitening agents on dental health and contribute to the advancement of knowledge in the field of dentistry.
