In what population percentage is the palatine torus considered "normal abnormality"?

The palatine torus is considered a common anatomical variation that can be found in the oral cavity. It occurs in the midline of the hard palate and is generally recognized as a normal abnormality due to its prevalence in certain populations. When discussing the prevalence of palatine tori, studies indicate that around 20% to 30% of the population exhibits this condition, confirming that a significant portion of individuals can have it without it being indicative of any health issue.

The choice indicating 30% is noteworthy as it aligns with the findings from various dental studies and literature, establishing the palatine torus as relatively commonplace among anatomical findings in the oral cavity. Understanding this phenomenon is important for dental assistants, as it helps them recognize variations in oral anatomy and informs their approach to patient assessments and dental hygiene practices.

Other percentages listed do not fully encapsulate the general consensus in the literature regarding the frequency of palatine tori, which is why they are not as representative of the characteristic's prevalence.
