Abstract
Objectives: To evaluate the shade selection accuracy of male dental students according to the three dimensions of color: value, hue, and chroma, using visual and instrumental shade selection methods under different lighting conditions.
Methods: This comparative cross-sectional study was instigated amongst 70 male 4th, 5th, and 6th years BDS students of the Dental Clinics Complex at King Faisal University, Saudi Arabia for a duration of two months. First, the principal investigator determined the shade of tooth 11 and 46 on patient utilizing the spectrophotometer after calibration. In the next step, students were asked to select the shade of same tooth 11 and 46 using VITA 3D-Master shade guide under clinic lightening condition and corrected light. The characteristics of the color such as hue, chroma and value were recorded. The Kruskal-Wallis test was applied to find the significant difference in shade selection between visual and instrumental methods with respect to academic years.
Results: The mean of the value of instrumental shade selection of tooth # 46 was slightly higher among 4th year students (4.41±0.73), than that of 5th year (3.72±1.02), and 6th year students (3.83±0.83), with a statistically significant difference among them (p= 0.024), indicating 6th year students selected darker shades. Additionally, a statistically significant relationship was noticed among 4th, 5th, and 6th year students with respect to the means of the chroma of 2.18 ±1.29, 2.92±1.11, and 3.13±1.10, respectively (p= 0.025).
Conclusion: The selection of posterior teeth shades was notably influenced by academic years, employing both instrumental and visual methods, while considering color parameters.
期刊介绍:
It is a peer reviewed medical journal published regularly since 1984. It was previously known as quarterly "SPECIALIST" till December 31st 1999. It publishes original research articles, review articles, current practices, short communications & case reports. It attracts manuscripts not only from within Pakistan but also from over fifty countries from abroad.
Copies of PJMS are sent to all the import medical libraries all over Pakistan and overseas particularly in South East Asia and Asia Pacific besides WHO EMRO Region countries. Eminent members of the medical profession at home and abroad regularly contribute their write-ups, manuscripts in our publications. We pursue an independent editorial policy, which allows an opportunity to the healthcare professionals to express their views without any fear or favour. That is why many opinion makers among the medical and pharmaceutical profession use this publication to communicate their viewpoint.
