ABSTRACT

Lamina dura is also known as the lining of the tooth socket made of a thin layer of dense bone and in some cases its
significance is a controversial issue. According to some dentists, in cases of complete or partial loss of lamina dura,
systemic conditions such as osteoporosis, hyperparathyroidism, Cushing's syndrome, Peyer's leukemia and some
other periapical diseases can be detected. Others believe that a radiographic increase in dural density may indicate
hypercementosis, osteopetrosis, or occlusal trauma. Dentists are therefore advised to study other signs and
symptoms, including the integrity of the lamina dura, when diagnosing disease or infection. Therefore, this article
mainly focuses on the importance of lamina dura in diagnostic purpose.
