We observed capsules of impacted teeth and follicular cyst walls with light microscope and electromicroscope. Further we compared the components of capsules with cyst walls by IR which lead to the conclusion that they are similar in morphological observation and components. Therefore there is a possibility that impacted teeth having capsules include the first stage of follicular cyst.
When impacted teeth have capsules, we can diagnose correctly using X-ray and histomorphological observation better than solely by X-ray.
