# Increased caries risk in a Xerostomic patient with Darier disease: a case report of incipient and advanced carious lesions

## TL;DR

A patient with Darier disease showed increased dental caries risk due to xerostomia and oral manifestations.

## Contribution

Highlights the link between Darier disease and dental caries through a case report with clinical management strategies.

## Key findings

- Xerostomia in Darier disease patients increases caries risk.
- Oral lesions and salivary gland involvement are common in Darier disease.
- Fluoride mouthrinse and restorative care are effective treatments for carious lesions in these patients.

## Abstract

Darier disease is a rare autosomal dominant inherited skin disorder, caused by mutations in the ATP2A2 gene. Oral manifestations can include mucosal lesions, salivary gland involvement, and xerostomia, that can significantly increase the risk of dental caries.

A 58-year-old female with a confirmed diagnosis of Darier disease presented with oral manifestations, including recurrent sublingual blisters, xerostomia, and carious lesions. The intraoral examination revealed white spot carious lesions and cavitated caries, particularly in the cervical areas of several teeth. Dental treatment included fluoride mouthrinse, oral hygiene instructions, and restorative care for the cavitated teeth. The patient was also advised on preventive and symptomatic measures for xerostomia.

Dentists should be aware of these potential issues and provide appropriate preventive, etiologic and symptomatic care. Regular follow-ups are essential to monitor the progression of dental lesions and manage oral health in patients with Dd.
