<p>Diagnosis and treatment of altered passive eruption: esthetic, restorative and hygienic concerns<br>Lieutenant Gregory L. Koontz, DC, USN and Commander Anthony J. Opilka, DC, USN<br><br>Introduction<br>In the military dental practice, every effort is made to address the dental needs of active duty members. However, due to deployments, training commitments, and at times a patient’s dental anxiety, esthetic issues may be left untreated. One such issue which may not be addressed until later in a patient’s career is short clinical crowns. Common causes of short clinical crowns include coronal destruction due to traumatic injuries, caries, or incisal attrition as well as from altered passive eruption. Normally when young recruits enter the military service eruption of their dentition is often complete. However, some patients may present with short clinical crowns above the gingiva making restorative and fixed prosthodontic dentistry challenging. In certain cases, excess gingival tissue may interfere with oral hygiene and plaque accumulates, resulting in gingival inflammation. This update will address the role of altered passive eruption in causing short clinical crowns, provide proper diagnostic information, highlight the essential clinical points to be observed, and present different treatment options for the restorative dentist.
