Which type of bone loss is most commonly associated with periodontitis?

Horizontal bone loss is characterized by a uniform reduction in bone height along the alveolar ridge, which is commonly seen in patients with periodontitis. This type of bone loss typically affects the bone surrounding the teeth symmetrically and is often the result of plaque accumulation, leading to inflammation and subsequent bone resorption.

In the context of periodontitis, the disease progresses in a manner that can result in horizontal bone loss, often observed in numerous teeth across an arch. This type of loss not only affects the structural integrity of the bone but can also influence the overall health of the periodontium and the stability of the teeth. While vertical bone loss, localized, and generalized bone loss can occur and may be associated with periodontal disease in specific situations, horizontal bone loss is more prevalent and characteristic in typical cases of periodontitis, making it the correct choice in this context.
