Which statement regarding biological width and the dentogingival complex is false?

The statement regarding mean dimensions from Gargiulo et al. reporting inconsistent findings regarding sulcus depth is identified as false because Gargiulo and his colleagues provided specific and consistent measurements related to the dimensions of biological width, which includes the sulcus depth as a critical component. Their research established that the average sulcus depth is around 0.69 mm. This data has been widely referenced in dental literature and is considered reliable, thereby dismissing the assertion of inconsistency.

In contrast, the other statements are accurate. Biologic width, defined as the space between the base of the gingival sulcus and the alveolar bone, is indeed the dimension of attached soft tissue situated above the bone, essential for periodontal stability. The relationship between restoration overhangs and the severity of bone loss is well-documented, indicating that improper restoration can contribute to periodontal issues. Additionally, crown lengthening can indeed be achieved through both surgical procedures and orthodontic methods, allowing for adequate tooth structure exposure while respecting biological width and health of the surrounding tissues.
