Frequency of Non-Bacterial Tooth Loss in the Millennial Generation of Rawalpindi and Islamabad, Pakistan
Objective: This study aimed to assess the prevalence of non-bacterial tooth loss mainly attrition, abrasion,
abfraction, erosion and acute trauma in the Millennial generation.
Materials and Methods: The study comprised 500 subjects divided into two groups, namely Group I (23-
31 years) and Group II (32-39 years) who were examined in the region of Islamabad and Rawalpindi from
September 2019 till January 2020. All subjects were examined with dental mirrors and torchlight to observe
tooth wear patterns that included attrition, abrasion, abfraction, erosion and acute trauma. The extent of tooth
wear was assessed according to the Smith and Knight Tooth Wear Index (1984) and acute trauma with the help of Classification by McDonald (2004).
Results: The prevalence of non-bacterial tooth loss observed was higher in Group I (45 individuals) than in
Group II (15 individuals). It was also found to be more significant in females than in males. The percentage of
tooth wear patterns observed was as follows: Attrition (9.6%), Abrasion (2%), Abfraction (0.2%), Erosion
(0.6%) and acute dental trauma (4.2%).
Conclusion: Out of all the tooth wear patterns examined attrition was the most commonly found, mainly in
subjects belonging to the underprivileged class. Other tooth wear patterns were not as significant.
