Which tooth type has a higher prevalence of furcation involvement?

Maxillary molars exhibit a higher prevalence of furcation involvement primarily due to their anatomical structure and position in the dental arch. These teeth typically have three roots, which increases the likelihood of periodontal disease affecting the furcation areas—the spaces between the roots—especially when plaque and calculus accumulate. The maxillary molars' furcation area is also more complex and challenging to clean effectively, making them more vulnerable to periodontal infection.

Additionally, because maxillary molars are positioned in the back of the mouth, they can be more difficult to access for proper oral hygiene compared to anterior teeth, contributing to a higher incidence of periodontitis and, subsequently, furcation involvement in these teeth. Understanding the unique characteristics of tooth morphology and their relationship to periodontal disease progression is crucial for effective diagnosis and treatment in periodontology.
