What is bimanual palpation in dental examination?

Bimanual palpation in dental examination refers to the technique where a clinician uses both hands, specifically employing the fingers and thumbs from each hand, to examine the intraoral or extraoral structures. This method enhances the ability to assess the size, shape, and consistency of tissues, as well as to identify any abnormalities more effectively than using just one hand or a single finger. By applying pressure with one hand while stabilizing with the other, the clinician can gain more comprehensive feedback about the anatomical structures being examined. This approach improves the palpation process by allowing for a more thorough evaluation and is especially useful in assessing lymph nodes, salivary glands, and other soft tissues in the head and neck region.
