Multiple roots give molars a decreased/increased periodontal disease | increased |
Why are molars lost to periodontal disease more than single rooted teeth? | because of the presence of furcations |
Long root trunks are more found more on the first molar or second? | Second Molar |
Molar furcations are too narrow for access by instruments resulting in? | Prognosis to see if periodontally involved. |
