PreClinic Practice Test

The col area is particularly prone to periodontal disease due to its specific anatomical and biological characteristics. This region is located in the gingival tissue between the interproximal surfaces of adjacent teeth, where it usually forms a depression. The col area is more susceptible to plaque accumulation because it is often confined and difficult to clean effectively during daily oral hygiene practices.

Furthermore, the col area has a thinner layer of keratinized tissue compared to other areas of the gingiva, making it more vulnerable to inflammation and infection. In addition, this region can be affected by the anatomical alignment of teeth that may lead to contact points that trap food and plaque. As a result, periodontal pathogens can thrive here, which ultimately increases the risk of developing periodontal disease.

The other areas listed, such as the maxillary occlusal surfaces, mandibular anterior teeth, and facial surfaces of molars, are less prone to periodontal disease when compared to the col area due to their different tissue structures and cleaning accessibility. These locations may experience issues related to caries or calculus formation, but they do not present the same level of susceptibility to periodontal conditions as the col.
