Diode laser removal of lower lip mucocele: a case report.

Mucocele is a common benign cyst pathology of minor salivary glands of the oral mucosa. The most common location for these lesions is the lower lip. It mainly occurs due to chronic trauma or habit of lip biting or sucking. Such parafunctional habits lead to the alteration of minor salivary glands and mucous accumulation. This case report presents a patient with lower lip mucocele resulting from a lip-sucking habit due to the presence of maxillary central incisor midline diastema. The mucocele removal was performed with a diode laser, and the midline diastema was closed with composite in order to eliminate the parafunctional habit of lip sucking and prevent a possible relapse.
