Highcusp

Highcusp is a term used in dentistry to describe an unusually long or prominent cusp, a pointed projection on the chewing surface of a tooth. This elongation can occur on any of the cusps, but is most commonly observed on the lingual (tongue-side) cusps of maxillary (upper) premolars and molars. The specific causes of highcusp development are not fully understood but are thought to involve genetic predisposition and developmental factors.

Clinically, a highcusp can present several challenges. Its increased height can lead to premature contact with opposing teeth during chewing, a condition known as a high occlusion or occlusal interference. This can result in uneven chewing forces, potentially leading to tooth wear, sensitivity, or even fracture of the highcusp itself or the opposing tooth. It can also contribute to temporomandibular joint (TMJ) disorders due to the altered bite forces.

Diagnosis of a highcusp is typically made during a routine dental examination through visual inspection and palpation. Articulating paper is often used to identify the specific premature contact point. Treatment strategies vary depending on the severity of the highcusp and its impact on the patient's occlusion. In mild cases, selective grinding of the highcusp by a dentist can reduce the premature contact and restore a balanced bite. For more severe or symptomatic highcusps, more extensive restorative work, such as crowns, might be necessary to reshape the tooth and protect it from further damage. Regular dental check-ups are important for monitoring any potential issues associated with highcusps.
