Contact area is in incisal/occlusal 1/3 in which tooth:
- A- Mandibular incisors.
- B- Mandibular molars.
- C- Maxillary molars.
the correct answer is: B- Mandibular molars.
The statement "Contact area is in incisal/occlusal 1/3" refers to the location of the area where teeth touch each other on their biting surfaces. Here's the breakdown of the options:
a. Mandibular incisors:
The contact area on mandibular incisors is typically located in the middle third of the incisal/occlusal surface, not the incisal/occlusal 1/3.
b. Mandibular molars:
In mandibular molars, the contact area is indeed located in the incisal/occlusal 1/3 of the surface. This is because molars have a larger occlusal surface compared to incisors, and the contact points are located further towards the biting edge.
c. Maxillary molars:
Similar to mandibular molars, the contact area on maxillary molars is also located in the incisal/occlusal 1/3 of the surface.
