Lip hyperpigmentation is an issue with the young adults when the dark brown patch on the lips makes an unsightly appearance. The laser energy is selectively absorbed by the melanin that causes pigmentation. This causes a photothermal ablation of melanocytes which leads to its disruption and subsequent removal by the body's immune system. It generally takes one to three treatments to lighten or remove unwanted pigmentation with laser. With most laser lip pigmentation removal, the pigmentation becomes darker for approximately 1 week and then flakes off. The treatments are spaced at least 1 month apart. There is also usually some redness and mild swelling in the treatment areas for a few days after treatment. The previous studies reported 100% clearance of pigmentation of the lips with a single laser treatment, and recurrence was not observed even after 6 months. This article highlights the use of 940 nm diode dental lasers for lip depigmentation procedure. Dental diode lasers have become a universal alternative tool for esthetic corrections of the oral cavity.

Pyogenic granuloma was first described in 1897 by two French surgeons, Poncet and Dor, who named this lesion botryomycosis hominis. Pyogenic granulomas and hemangiomas of the oral cavity are well-known benign lesions. Although, pyogenic granuloma is known to show a striking predilection for the gingiva and capillary hemangioma for lips, cheek and tongue, palatal occurrence of these lesions is extremely rare. The clinical diagnosis of such an uncommon occurrence can be quite challenging, as they sometimes may mimic more serious lesions such as malignancies. The purpose of this article is to report an unusual case of benign tumor occurring on hard palate, which was clinically diagnosed as pyogenic granuloma and histopathologically as capillary hemangioma. The treatment options available are conventional surgical excision; electrocautery and lasers-erbium or diode. This article highlights the use of 940 nm diode laser in surgical excision of oral pyogenic granuloma enumerating its advantages over the conventional available treatment options.

Ossifying fibroma mostly occurs in the craniofacial bones and is generally categorized into two types, namely, central and peripheral ossifying fibroma. The peripheral type occurs solely on the soft tissue overlying the alveolar process and is 'nonneoplastic'. It is a common gingival growth that usually arises from the interdental papilla. The etiology and pathogenesis of peripheral ossifying fibroma (POF) is unclear. It is thought to arise from the cells in the periodontal ligament. Trauma or local irritation, such as dental plaque, calculus, ill-fitting dental appliances and poor-quality dental restorations are all known to precipitate in the development of POF. Clinically, differential diagnosis includes peripheral giant cell granuloma, pyogenic granuloma, fibroma and peripheral fibroma. Treatment of POF consists of elimination of etiological factors, scaling and root planing of involved teeth and total aggressive surgical excision. Another option available in place of the conventional surgical excision is the excision using lasers. A new addition to this generation of lasers is Er,Cr:YSGG laser. The aim of this paper is to analyze the effectiveness of Er,Cr:YSGG laser in the treatment of POF. The outcome in this case was painless experience to the patient, minimal intraoperative bleeding in the surgical field and excellent healing of the operated area in 1 week period, concluding as one of the best treatment option available for excision of POF.

Neurofibroma is an uncommon benign tumor of the oral cavity derived from the cells that constitute the nerve sheath. The cases of oral cavity involvement by a solitary and peripheral plexiform neurofibroma in patients with no other signs of neurofibromatosis is uncommon. Sporadic cases have been reported in the submandibular gland, tongue and on the periosteum at the mental foramen. The World Health Organization (WHO) has subdivided neurofibromas into two broad categories: dermal and plexiform. The dermal neurofibromas arise from a single peripheral nerve, while the plexiform neurofibromas are associated with multiple nerve bundles. The aim of this paper is to analyze the effectiveness of diode laser in the treatment of neurofibroma of a solitary lesion on the tongue. The advantages of using lasers in this case report was a bloodless and painless experience for the patient with excellent healing of the operated site after a period of 1 week.
