Aim: There is an increased awareness for aesthetically pleasing restorations among patients in current practice. Due to variability in the natural tooth colour, shade selection becomes an intricate procedure. The aim of this study is to determine which of the three named methods is more accurate for shade selection in aesthetic dentistry.
Materials And Methods: Two VITAPAN classical shade guides were used for this study. Nine shades were selected from the first shade guide (A1, A2, A3.5, B1, B2, B3, C1, C2, C3) and the number was concealed. Ten selected participants were asked to identify each concealed shade with the second shade guide. Canon 5D camera with ISO 200, shutter speed 1/100 sec, F22 was used for capturing images of the second shade guide. Photoshop CS3 Software was used for developing the digital shade guide. The participants were asked to match the shades from the first shade guide with the prepared digital shade guide. The third photographic shade guide was prepared using a polarised filter on the Canon 5D camera with the same settings. The participants were asked to match shades with the prepared photographic shade guide.
Results: Total observations made during the study were 270. Cross table statistical analysis (Chi-square test) done using SPSS 20.0 showed statistically significant difference between conventional and digital photography (P = 0.049). Analysis between digital photography and polarizing filter photography did not reveal a significant association (P = 0.181).
Conclusion: Digital photographic method was most accurate among the three shade selection methods. It can be used to obtain aesthetic results.

Background: This single-blind, noninferiority trial evaluated whether 10% carbamide peroxide (CP) applied for 2 or 4 hours daily is noninferior to 8 hours.
Methods: A total of 120 healthy adults, with teeth shade A2 or darker, were randomly allocated to 3 groups (n = 40). All participants used 10% CP gel in a bleaching tray for 2, 4, and 8 hours daily for 14 days, with the option to extend treatment if they were dissatisfied.

Objectives: The study aimed to assess the percent correct shade identification of four intraoral scanners (IOS) and a spectrophotometer, focusing on how reliably each device selects the correct tooth shade compared to a visual observer's selection. The research question addresses how much clinicians can trust the device-selected shade without visual verification.
Materials And Methods: Sixteen participants with natural, unrestored teeth were included.

Objectives: This study aimed to compare the efficacy of two non vital whitening techniques, In-office and Walking Bleach, using 35% hydrogen peroxide. The primary research question was to determine which technique achieves greater tooth color improvement.
Materials And Methods: Fifty non-vital anterior teeth with discoloration were randomly assigned to either the In-office (n = 25) or Walking Bleach (n = 25) groups.

Objective: To provide guidelines and means for optimal coverage and distribution of computer models with 1-10 clusters, designed based on an in vivo extensive dental colorimetric database and compare the findings with some reputable shade guides.
Materials And Methods: The Fuzzy C-Means (FCM) algorithm was used to optimize the tab position in the CIELAB color space, while MATLAB Fuzzy Logic was used to implement the codes. A minimization process was performed to fine-tune the cluster centers, minimizing Coverage Error (CE) and Maximum Error (ME).
