Angular bone resorption is most commonly associated with periodontosis, which is often characterized by the loss of bone and periodontal attachment due to an inflammatory response. This condition leads to the breakdown of the normal supporting structures around teeth, particularly in advanced stages, resulting in angular defects in the bone around the teeth.

In periodontosis, the constant presence of plaque and calculus can cause a chronic inflammatory reaction, which affects the bone around the teeth. The pattern of bone loss tends to be more pronounced in areas where the periodontal attachment is weakened, leading to the characteristic angular defects.

On the other hand, while occlusal traumatism, food particle retention, and gingivitis can lead to different types of periodontal issues or localized inflammation, they do not specifically result in the angular bone resorption seen in periodontosis. Occlusal traumatism typically leads to bone resorption in a more general pattern without the specific angularity observed in periodontosis, while food particle retention is more associated with localized plaque accumulation rather than widespread bone loss. Gingivitis primarily causes inflammation of the gums without direct bone loss, making periodontosis the clear association with angular bone resorption.
