For a patient needing osseous resective surgery, which condition would make the procedure most suited?

  1. Late-stage periodontitis with extensive bone loss

  2. Early to moderate bone loss with periodontitis

  3. Gingival recession with no bone loss

  4. Acute necrotizing ulcerative gingivitis

The correct answer is: Early to moderate bone loss with periodontitis

Periodontitis is an inflammatory disease that affects the gums, periodontal ligaments, and bone that surrounds and supports the teeth. If left untreated, it can lead to gum recession and bone loss, making the teeth lose and eventually fall out. This condition is progressive and it is important to address it as early as possible to prevent extensive damage. Therefore, the procedure of osseous resective surgery is most suited for cases where there is early to moderate bone loss along with periodontitis. This means that the bone loss is not yet extensive, allowing for successful surgical intervention without compromising the integrity of the remaining bone and teeth. As such, none of the other options are the most suited because A, C, and D do not involve periodontitis and therefore, do not require osseous resective surgery.
