Clinical threshold of the translucency parameter of maxillary central incisors

The aim of this in vivo study is to describe the clinical threshold and relative factors associated with translucency maxillary central incisors. Bilateral incisors were measured 106 individuals using a digital colorimeter against black white backings. parameters (TP) difference TP (?TP) between left right same individual was calculated. mean value 8.22. There significant effect age on (p<0.05). females higher than that males absolute ?TP 1.33. two can be used as reference for translucency.
