Abstract:
Osteopoikilosis (OPK) is a rare benign bone dysplasia characterized by the presence of multiple radiodense patches scattered throughout the skeleton's trabecular bone. It presents as small well-demarcated bone lesions of variable sizes and of a sclerotic nature. OPK is a benign bone pathology that requires no treatment but monitoring and management of possible symptoms. This case highlights the incidental finding of an asymptomatic OPK in the mandible of a patient seeking orthodontic treatment; OPK manifestation in the mandible was rarely reported before. Radiologic and clinical diagnoses, along with the family history, confirmed the differential diagnosis of OPK. Such a differential diagnosis includes a range of serious conditions such as osteoblastic metastasis and tuberous sclerosis, making the correct diagnosis of OPK essential for overtreatment prevention. Treatment consisted of patient education, follow-up, and anti-inflammatory drugs in case of symptomatic flare-ups. This article reports on a case of OPK presenting lesions in the mandible as well as in other bones of the skeleton; such a manifestation of OPK in the cranium and specifically in the mandible is considered extremely rare.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
The Hyoid Bone
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
Oral Cavity
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
