In young adults, an obtuse gonial angle is associated with a tendency towards what?

Deep overbite
Open bite
Crossbite
Underbite

The correct answer is: Deep overbite

In young adults, an obtuse gonial angle refers to the angle formed by the intersection of the mandibular plane (the line connecting the lower teeth to the chin) and the ramus (the vertical part of the jawbone). An obtuse angle in this area is commonly associated with a deep overbite, which is when the top front teeth significantly overlap the bottom front teeth. This is due to the fact that an obtuse gonial angle can lead to a longer lower face height and a higher mandibular plane angle, both of which are factors in developing a deep overbite. The incorrect options, open bite, crossbite, and underbite, are associated with different angles or patterns of teeth alignment and do not directly relate to the gonial angle.
