Summary
Keratocystic odontogenic tumor (KOT) is a common oral lesion, frequently occurring in the jaw. Recurrence rates are lower in males, with the mandible being the most common site.
Area of Science:
- Oral and Maxillofacial Surgery
- Pathology
- Oncology
Background:
- Keratocystic odontogenic tumor (KOT) is a developmental odontogenic cyst with a high recurrence rate.
- Understanding KOT epidemiology is crucial for effective management and treatment planning.
Purpose of the Study:
- To determine the frequency of KOT at the Oral Surgery Service (OSS) of HUCFF/UFRJ.
- To analyze KOT recurrence rates, gender distribution, age at recurrence, and lesion location.
Main Methods:
- Retrospective review of clinical records and histopathological reports of KOT patients from 2002 to 2012.
- Patients were categorized into recurrence-positive (n=6) and recurrence-negative (n=19) groups.
Main Results:
- KOT was the second most frequent lesion observed.
- The mandible was the most common location for KOT.
- Recurrence rates were lower in males, with equal gender distribution in the recurrence-positive group.
Conclusions:
- KOT is a significant oral pathology with a predilection for the mandible.
- Male patients exhibit lower recurrence rates.
- The findings contribute to understanding KOT behavior and risk factors.

Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the...

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...

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.

The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
