The small tooth bottom center is the primary canine that has not fallen out because the permanent canine has become impacted in an abnormal direction. DiseasesDB ICD10 ICD10 K 01 k 00 ICD9 ICD9 520.6 ICDO OMIM MedlinePlus eMedicineSubj eMedicineTopic MeshID Impacted and embedded teeth are the two main types of unerupted teeth found in the mouth , and can sometimes be confused with each other. Deleted image removed File Xray of Four impacted teeth01.jpg thumb 250x right An orthopantomogram revealing four impacted Third molar Wisdom teeth . In cases of both impacted and embedded teeth, the teeth remain below the surface of the gingiva gum and sometimes bone , rather than erupting into an exposed position within the mouth however, the reason for the failure to erupt differs. Impacted teeth result from a situation in which an unerupted tooth is wedged against another tooth or teeth or otherwise directed so that it cannot erupt normally. In contrast, an embedded tooth is an unerupted tooth that is covered, usually completely, with bone . The former is physically blocked in its path of eruption, while the latter is compromised by its lack of eruptive force often without known etiology. Certain systemic and local pathologic conditions may be associated with both i.e., cleidocranial dysostosis . Impaction classifications There are numerous classification systems used to identify the specific manner in which a tooth is impacted. One of the most simple distinctions made is whether a tooth is impacted completely within bone or whether it has broken through the bony cortex and is partially or completely covered in gingiva gingival tissue the former would be termed bony impaction , while the latter would be termed soft tissue impaction , and both classifications may present as partial or complete. ref http www.animated teeth.com wisdom te ... more details

Merge to Orthopantomogram date January 2011 Panoramic radiographs were developed by dentists to visualize the entirety of the upper maxilla and lower mandible jaws including the teeth, maxillary sinuses, and nasal cavity. This imaging system however also has the capability to simultaneously demonstrate a portion of the neck and display atheromas calcifications in the carotid artery which are an indication of both local and generalized systemic atherosclerosis. Atherosclerosis of the coronary arteries leading to myocardial infarction heart attack , and atherosclerosis of the carotid artery leading to stroke are the number one and number three most common causes of death in the United States. ref name ref3 American Heart Association s Heart Disease and Stroke Statistics 2010 Update http www.americanheart.org downloadable heart 1265665152970DS 3241 20HeartStrokeUpdate 2010.pdf ref Dentists Historic Role in Cardiovascular Disease Detection During the past thirty five years, research activities have focused upon enhancing the ability of dentists to participate in cardiovascular disease detection programs beyond the historical limitations of screening for hypertension and offering assistance with smoking cessation.

The lower left wisdom tooth is horizontally impacted. The lower right wisdom tooth is vertically impacted unidentifiable in orthopantomogram . Impacted wisdom teeth i.e., those that have failed to erupt through the gum line fall into one of several categories Mesioangular impaction is the most common form 44 , and means the tooth is angled forward, towards the front of the mouth. Vertical impaction 38 occurs when the formed tooth does not erupt fully through the gum line. Distoangular impaction 6 means the tooth is angled backward, towards the rear of the mouth. Horizontal impaction 3 is the least common form, which occurs when the tooth is angled fully 90 degrees sideways, growing into the roots of the second Molar tooth molar .
