Background and Aim: Generation defines as a group of people who were born in a same interval of year and shares similar life events at critical developmental stages, values, behaviors, and significant reactions. The aim of this clinical study was to assess self-awareness of dental health of X, Y, and Z generations in Turkey. Materials and Methods: Total of 239 individuals were divided into three homogenous groups X Generation (X Gen; n = 80), Y Generation (Y Gen; n = 80), and Z Generation (Z Gen; n = 79) by their date of birth 1965-1980; 1981-2000; 2001-2013, respectively. Self-rated caries status, frequency of tooth brushing, frequency of dental visits, and actual caries status were recorded. Self-awareness was calculated as the extraction of the numbers of actual caries and self-rated caries and coded as o Caries. Results: Mean Dental caries status was recorded using the number of decayed, missing or filled teeth (dft/DMFT) was 4.92 for X Gen; 4.68 for Y Gen; 3.66/3.51 for Z Gen individuals, respectively. Actual caries and self-rated caries were significantly incompatible with each other in all study groups (<0.001). oCaries were insignificant in X, Y, and Z Generations (>0.05); nevertheless, self-awareness (self-rated caries = actual caries) of Z Gen were found numerically more (23%) compared to other groups. Tooth-brushing habits of all individuals were mostly once-a-day (>0.05). Mean frequency of dental visits were once in a 3.5; 2.9; 1.5 years for X, Y, and Z Gens, respectively. Conclusion: There is no significant correlation between frequency of dental visits and self-awareness measures. Oral health education should urgently point out for all generations by dental professionals, media, and governmental authorities including preventive methods, oral hygiene instructions all aimed at preventing caries and raising self-awareness.
