“…This parameter is least affected by environmental factors and the pathological process. [6181920] It also shows symmetrical distribution on both sides of the jaws. [1821] Furthermore, translucency can be assessed macroscopically on intact teeth, although tooth sections provide better detail.…”

Background:Dentin translucency is best suited for age estimation not only in terms of accuracy but also in terms of simplicity. Conventionally, translucency has been measured using calipers. Computer-based methods have been proposed for the same, although these required the use of custom-built software programs.Objectives:The objectives of the study were to use a simple digital method to measure dentinal translucency on sectioned teeth and to compare digital measurements to conventionally obtained translucency measurements.Materials and Methods:Fifty extracted permanent teeth were collected and were sectioned to 250 μm. Translucency measurements were obtained using the digital method and compared with those obtained using a caliper.Results:Correlation coefficients of translucency measurements to age were statistically significant for both methods (P < 0.001), and marginally higher for the conventional approach (r = 0.4671). Application of derived linear regression equations on an independent sample (n = 10) revealed a similar ability of both the methods to assess age to within ±5 years of the actual age.Conclusion:The translucency measurements obtained by the two methods were very similar, with no clear superiority of one method over the other. Hence, further studies on a large scale are warranted to determine which method is more reliable to estimate the age.

“…All of the measurements were carried out on nonsectioned teeth. Once the measurements (in millimeters) of periodontal attachment loss, root length, and translucency for each dental element were obtained, the equations proposed by Lamendin et al (21) and Prince & Ubelaker (20) and from Singhal et al (22) were applied to estimate age. A statistical analysis using linear regression models was then carried out with the aim of evaluating the correlations between known age and dentinal translucency ( Fig.…”

Age estimation of nonliving subjects plays a very important role in identifying human remains. When adult remains are in question, this process becomes even more complex. Among the numerous dental methods that exist for adults aging, the evaluation of root translucency is one of the most useful. This study studies the correlation between age and root translucency by investigating monoradicular teeth affected by pathological processes using the equations proposed by Lamendin, Prince & Ubelaker and from Singhal et al. The average age values calculated according to the three methods were compared with the values of known age. Age estimation using the Student's t-test resulted as more accurate in the methods by Singhal et al. and by Prince & Ubelaker, with respect to that of Lamendin. Age estimation based solely on the percentage of radicular dentinal translucency has been found to be more accurate when diseased teeth are involved.

“…Data recommended for use as reference in the development of esthetic restorative materials and clinical shade matching were presented using both CR and TP determinations . Ground 400‐μm sections of root dentin stained with 1% methylene blue were visually assessed for a relationship between root translucency and the subject's age . Vital natural unrestored teeth were analyzed by a digital imaging and shade analysis device, which was used to indicate areas of visually noticeable tooth translucency …”

The method of specifying the translucency of esthetic dental materials may be based on clinical appearance requirements of the patient, on technical demands of optimizing the setting of underlying material, or on both. The method or methods used to describe translucency may provide clinically relevant information in order for the clinician to select the optimum material to satisfy these requirements.
