Question: 1 / 1775

What does 'lacuna' refer to in dental terminology?

Type of dental cavity

Small open space in cementum

In dental terminology, 'lacuna' refers specifically to a small open space found within the cementum, which is the hard tissue that covers the roots of teeth. These lacunae serve as sites for osteocytes, which are bone cells, to reside and maintain communication with each other and with the surrounding mineralized tissue. Understanding the role of lacunae is essential, as they contribute to the health and maintenance of the periodontal ligament and cemental tissue, crucial components in tooth stability and overall oral health. This differentiation from types of dental cavities, enamel defects, or gum tissue is key in understanding both histological structures and their implications in dentistry.
