👉 The Barry fluid, also known as the Barry's exudate or fluid from the Barrington's gland, is a clear, viscous secretion found in the oral cavity, particularly around the tongue and floor of the mouth. It is primarily composed of water, proteins, electrolytes, and mucins, and serves as a protective barrier against microbial invasion and mechanical damage. This fluid plays a crucial role in maintaining oral health by lubricating the oral tissues, facilitating speech and swallowing, and contributing to the overall balance of the oral microbiome. Its presence can be indicative of various conditions, including oral infections or inflammatory processes, making it a valuable diagnostic marker in dentistry and oral medicine.
