Summary
Mandibular cortical bone in healthy children varies by gender and age, with girls showing smoother bone margins. Dental status did not impact bone morphology or thickness.
Area of Science:
- Paediatric dentistry
- Oral and maxillofacial radiology
- Human anatomy
Background:
- Mandibular cortical bone changes are known in children with chronic diseases.
- Limited data exists on mandibular cortical bone in healthy children.
Purpose of the Study:
- To qualitatively and quantitatively assess mandibular cortical bone in healthy children aged 6-18 years.
- To evaluate the influence of dental status on mandibular cortical bone characteristics.
Main Methods:
- Dental panoramic radiographs (DPTs) of 660 children were analyzed by two blinded examiners.
- Mandibular Cortical Index (MCI) for qualitative assessment and Mandibular Cortical Width Index (MCW) for quantitative assessment were used.
- Statistical analysis included Fisher's exact test, chi-square test, and correlation analysis.
Main Results:
- Significant gender differences in bone morphology were observed; girls had more even endosteal margins, while boys exhibited semilunar defects.
- Bone erosion and thickness increased with age.
- A positive correlation between bone thickness and mixed dentition was noted.
- No correlation was found between bone morphology/thickness and dental status.
Conclusions:
- Mandibular cortical bone quality and quantity exhibit significant variation based on gender and age in healthy children.
- Dental needs and treatment characteristics did not appear to influence mandibular cortical bone parameters.

01:27Compact Bone
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
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...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
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 grinding food.
