Which of the following is unlikely to occur if the biologic width is violated by a restoration?

When biologic width is violated by a restoration, several undesirable outcomes can occur due to the disruption of the supportive periodontal structures. The biologic width refers to the space on the tooth surface that is occupied by the junctional epithelium and connective tissue attachment. If this space is invaded or violated, it can lead to pathological changes.

Chronic pain and chronic inflammation are likely outcomes of such a violation. Pain often arises due to irritation of the surrounding periodontal tissues, which can become inflamed as they react to the abnormal positioning of the restoration and the potential for bacterial colonization. Inflammation can persist over time, leading to chronic conditions if the source of irritation is not addressed.

Additionally, unpredictable loss of alveolar bone may occur when the restoration encroaches upon the biologic width, leading to the breakdown of periodontal support. When the biologic width is not respected, tooth mobility and periodontal disease may ensue, which can ultimately result in bone loss.

In contrast, an enhanced crown to root ratio is unlikely to occur if the biologic width is violated. The crown-to-root ratio is a term used to describe the proportional relationship between the portion of the tooth seen above the gum line (crown) and the portion embedded in the bone
