Where does bunching occur on the dental dam during application?

On the occlusal side
On the buccal side
On the lingual side
On the incisal edge

The correct answer is: On the lingual side

Bunching on the dental dam occurs on the lingual side during application due to the way the dam is placed over the teeth. When the dam is stretched and placed, especially in areas where teeth are closely positioned or if there is an irregularity in tooth alignment, it can lead to excess material gathering or bunching on the lingual side. This is primarily because the dam is being pulled taut over the arch of the teeth, and any extra material needs to accumulate somewhere. In many cases, dental professionals may observe that as the dam is placed, the lingual side has to accommodate that excess material, leading to the bunching that can impact visibility and access for procedures being performed. Being aware of where this occurs is important for ensuring a proper application and minimizing disruption during dental work.
