Abstract
|
|
|
Hypercementosis is an excessive deposition of secondary cementum on the root of a tooth. It is mostly presented as a solitary lesion or in rare cases as a generalized type, but which is seldom recognized; typically it is discovered during regular dental X-ray. Increased thickness of cementum is not uncommon but generalized hypercementosis on impacted permanent teeth which may cause delayed eruption is rarely reported.
This case report discusses a patient with cerebral palsy, epilepsy and mental retardation that presents multiple hypercementosis with delayed eruption. On intraoral examination, multiple retained primary molar teeth were found. As there was no any further symptoms, regular dental checkup had been done for several years. In 2015, a surgical opening was performed in the second molar area, but there was no specific change. Panoramic view showed multiple impacted permanent teeth with increased thickness of roots due to excessive deposition of cementum. Hypercementosis was also observed in the root of the erupted tooth. Several laboratory test results including hormone, urine, complete blood count test were reviewed. The patient was also diagnosed with subclinical hypothyroidism, impaired fasting glucose and had been taken valproic acid(Orfil®) for 10 years. However, none of them clearly explained generalized hypercementosis or delayed eruption. The patient is now 24 years old and regular dental checkups and radiographs are taken to confirm that there is no change in the lesion.
