Where are the narrowest bands of attached gingiva typically found?

The narrowest bands of attached gingiva are typically found in the buccal areas of the mandibular canines and first premolars. This area is characterized by a narrower width of attached gingiva compared to adjacent teeth because of the underlying anatomical structures, including the proximity to the mandibular vestibule. This anatomical feature can result in a reduction of keratinized tissue in these regions, which is crucial for maintaining the health and integrity of the gingival tissue. Understanding this aspect is vital in clinical practice, especially when considering periodontal assessments and surgical interventions like grafting, where adequate attached gingiva is a significant factor for successful outcomes.
