Dental fluorosis has a very typical presentation in terms of tooth surface appearance and oral distribution. Overall, there is increasing clinical evidence for reducing the severity of fluorosis during adolescence for all permanent teeth and into early adulthood. The teenagers in Riyadh participated in this cross-sectional study. 383 kids were included through practical sampling after Riyadh's schools were contacted. Fluorosis was found to be 26% prevalent overall, according to the findings. The most frequent form of fluorosis was described as "very mild," and the least frequent form was described as "questionable." Fluorosis in the teeth is less common than it once was. The age of participants had no significant impact on the prevalence or severity of dental fluorosisAccording to Dean's index of fluorosis, 1% of people had uncertain dental fluorosis, 42% had very mild fluorosis, 25% had mild fluorosis, 17% had moderate fluorosis, and 15% had severe dental fluorosis (Figure 3). Additionally, age groups were used to compare the prevalence of dental fluorosis, but there was no statistically significant difference (p-value:.725). The overall prevalence of dental fluorosis is on the lower side. Prevalence as well as severity of dental fluorosis was not significantly associated with the age of participants.
