Following anthropometry and oral examination, maximum occlusal force, lip-closing strength, maximum tongue pressure, and masticatory performance were measured in all participants. The Rohrer Index and body mass index (BMI) were calculated using height and weight measurements, and these scores were grouped into underweight/severely underweight, normal weight, and overweight/obese categories.</p></div><div><h3>Results</h3><p>In males, maximum occlusal force, lip-closing strength, maximum tongue pressure, and masticatory performance increased with age. In females, maximum occlusal force, maximum tongue pressure, and masticatory performance peaked during the teenage years.

Oral functions in females typically reached their peak earlier than in males, with most functions peaking during the teenage years.
