on the results of endodontic treatment. Knowledge of these changes is essential in order to design treatment strategies that allow aging people a life with constant dental health. Objective: The objective of this study sought to perform an analysis of the histological changes that occur within dental pulp as a result of aging. Study Design: This is a cross-sectional study. Duration and Place of the Study: This study was conducted at Department Anatomy of General Hospital and Research Centre, Peshawar, from 3rd November 2022 to 2nd December 2023. Material and Methods: A total of 220 patients aged between 20-80 years, were admitted to this survey. According to age, they were classified into 20-29 years (n=41), 30-39 years (n=39),40-49 years (n=48), 50-59 years (n=45 ) and 60 -80 years( n=47). Extraction of dental pulp samples Pulp tissues were harvested from teeth that had been extracted for non-dental reasons. Histological analysis for cellularity, vascularity and fibrous content of the pulp tissue. Results: A total of 220 patients aged between 20 and 80 Years were included in this study. The biggest group of people was participants 40-49 years old (21.8%), and the smallest one is for 30-39-year-olds with (17.7%). The study found that Participants of the age groups 20–29 years showed a mean cellularity (1500 cells/mm²), with standard deviation of ±200, while those in the 60-80 years group had the lowest mean cellularity at 800 cells/mm² with a standard deviation of ±160. Conclusion: The histological changes in dental pulp with ageing have as consequences implications on endodontic treatment.
