Abstract

Background: A captivating smile is the epitome of aesthetic dentistry, heavily reliant on meticulous shade matching with natural teeth. However, achieving optimal shade matching necessitates a profound understanding of various factors influencing tooth color perception and the intricacies of shade selection methods. This study aims to determine the predominant tooth shades within the Hyderabad, Sindh population, shedding light on shade distribution trends across different age groups and genders. The primary goal is to equip local dentists with data-driven insights to refine their shade-matching skills, ultimately enhancing patient satisfaction and aesthetic outcomes.


Materials and Methods: A retrospective analysis of dental records from various clinics in Hyderabad, Sindh, Pakistan, was conducted. The study included 400 patients who underwent crown or bridge treatments. Data on age, gender, and tooth shade were collected and analyzed using statistical methods.


Results: The majority of treatments involved crown placements (71.0%), with the Vita Shade Guide exclusively utilized for shade selection. Patient satisfaction following cementation was high, with 48.0% reporting satisfaction and 52.0% reporting strong satisfaction. Significant associations were observed between tooth shade, age, and gender. A2 emerged as the most prevalent shade, with variations noted across age groups and genders.


Conclusion: A2 was identified as the predominant tooth shade in Hyderabad, Sindh, with notable associations between shade, age, and gender. Understanding these nuances is crucial for enhancing shade-matching accuracy and patient satisfaction in dental restorations. Further research is warranted to develop tailored shade selection protocols for diverse populations.
