Lower lip mucocele treated with an erbium laser.

Mucoceles are benign lesions of the minor salivary glands that are common in children. The most frequent localizations of these lesions include the lower lip and the cheek mucosa. Such mucoceles are caused by traumas, the rubbing of orthodontic devices, or biting habits. The purpose of this article was to describe the case of a 4-mm extravasation mucocele located on the lower lip of a 9-year-old girl. This mucocele was removed with an erbium loser after perilesional infiltration with 12 mg of 2% lidocaine and epinephrine 1:100,000. The histopathological report confirmed the presurgical diagnosis. The wound healed excellently and rapidly without sutures. No relapse was observed a year ofter the surgery. Lasers apply modern technology and are useful for soft tissue surgery in pediatric dentistry, as operations are rapid and wounds heal well without sutures.

Erbium laser treatment of an impacted first mandibular premolar: a case report.

Dental impaction defines a tooth that, instead of erupting to occupy its functional position, is partially or totally retained and remains within the bone. Retained teeth can be placed in the normal arch position through a combination of orthodontics and conventional surgical techniques, or a combination of orthodontics and laser surgery, as in the case here presented of a 14-year-old boy with an impacted first mandibular premolar, covered by bone, and with complete root formation and an erupted second premolar. The impacted premolar was surgically exposed using an Er,Cr:YSGG laser and at the same time an orthodontic bracket was bonded to provide traction to move the first premolar into its arch position.

Laser treatment of an oral papilloma in the pediatric dental office: a case report.

Squamous cell papilloma is a benign proliferation of the stratified squamous epithelium. It is typically an exophytic lesion smaller than 1 cm. Its appearance varies from cauliflower-like to fingerlike, while the base may be pedunculated or sessile. This article describes the case of an 11-year-old girl who presented with an asymptomatic whitish lesion of papillomatous appearance in the oral mucosa distal to the maxillary left permanent first molar. The lesion was removed using an Er,Cr:YSGG laser. For anesthesia, 10 mg of 2% lidocaine with epinephrine 1:100,000 was infiltrated around the lesion. No pain medication was required after surgery, and wound healing was excellent and rapidly achieved. The oral pathology report confirmed the presurgical clinical diagnosis. Laser dentistry is a modern technology that can be used by dental clinicians to treat these kinds of oral lesions and should be considered as an alternative to conventional surgery.

Laser-assisted treatment of a dentigerous cyst: case report.

Dentigerous cysts are benign maxillary odontogenic cysts associated with the crown of an unerupted tooth. They can expand the cortical bone to such an extent that they cause displacement of teeth and root resorption in the adjacent teeth. The purpose of this report was to describe the clinical case of a dentigerous cyst in a mandibular permanent molar of a 6-year-old child. The cyst caused the displacement of the bud of the permanent second molar and root resorption of the primary second molar. The cyst was treated by: (1) mucous fenestration using an erbium laser: (2) drainage of the fluid content; and (3) curettage of the bone cavity. The injury was successfully resolved in just 5 months with: (1) bone regeneration; (2) the repositioning of the displaced bud; and (3) correct eruption of the affected tooth.
