Eruption cysts are benign cysts that appear on the mucosa of a tooth shortly before its eruption. They may disappear by themselves but if they are hurt, bleed, or are infected, they may require surgical treatment to expose the tooth and drain the contents. Here we present a clinical case of a 12-year-old child with an eruption cyst in mandibular right second molar treated using diode laser. No hemorrhage, swelling, infection or postoperative pain was observed. Treatment of eruption cysts with this technique facilitates obtaining a cooperative behavior from pediatric patients and makes behavior management easier.

  Introduction Top

Eruption cysts are benign cysts that appear on the mucosa of a tooth shortly before its eruption. [1] They are considered as dentigerous cyst or follicular cyst, but are recognized as separate clinical entity since they appear only in soft tissue. [2] Eruption cyst produces a smooth, fluctuant painless swelling over the erupting tooth of either the color of normal gingiva, or pale blue. It may either impede tooth eruption or may disappear on their own. [1] However, the highest percentage has been associated with eruption of permanent teeth between ages of 6 and 11. [2]

This article presents a clinical case of an eruption cyst in left second mandibular molar treated using a diode laser.

  Case Report Top

A 12-year-old child with a swelling that evolved 7 days back in alveolar ridge in left mandibular region at the level unerupted permanent mandibular second molar complained of pain during palpation and mastication [Figure 1].

Clinical examination revealed a bluish area on the gingiva above the unerupted permanent mandibular right second molar. It was bright and soft to touch. Radiographically, no significant alterations were observed, confirming the clinical diagnosis of an eruption cyst.

Topical anesthesia, 2% lignocaine spray was applied for 2 minutes after drying the mucosa on the cyst. An incision was made using diode laser on the level of alveolar ridge of nonerupted second molar. An output of 1.6 watts was used as recommended by manufacturer for soft tissues. Bleeding was very minimal. Once tooth was uncovered the bloody fluid inside the cystic cavity oozed out. Postoperatively patient was advised mild analgesics if required along with topical application of Vitamin E thrice daily for 4 days. There was no hemorrhage, swelling, infection or postoperative pain [Figure 2]. A week later, no postsurgical complications were observed [Figure 3].

  Discussion Top

Conventional treatment for eruption cysts was marsupialistion. Incision or partial excision of the dome of the cyst was done to uncover the crown of the tooth involved followed by draining the liquid content of the cyst. [2] Other treatment options included simple incision to uncover the tooth and drain the cystic fluid. [3] This facilitates the eruption of the involved tooth.

The diode laser system is an excellent tool since it eliminates the need for local anesthesia in most cases, which is an advantage in treatment of eruption cysts. The painless character of laser has been attributed to its transitory anesthetic effect due to the blocking of the nervous conduction in Na/K pump. [4]

Lasers do not produce heat or friction. [5] The patient is comfortable, not noticing the sensation of vibration or observing the contact of the laser handpiece with the mucosa. [4] Due to lack of use of local anesthesia, the possibility of complications, toxicity, allergic reactions are eliminated.

The diode laser has bactericidal and coagulative effects. Compared with conventional scalpel there is mild bleeding and better visibility of working area. [6] When laser cutting is in progress, small blood and lymphatic vessels are sealed due to the generated heat, thereby reducing or eliminating bleeding and edema. Clinically, during 48-72 hours postsurgery, this layer becomes hydrated from saliva, swells, and eventually disintegrates to later reveal an early healing bed of new tissue. [7]

Tissue healing followed by laser is better and faster than tissues treated with conventional surgery, with reduction in scar tissue retraction, bleeding, edema and post-operative pain. [6]

  Conclusion Top

The treatment of eruption cysts with laser technique facilitates obtaining the cooperation of pediatric patients and makes behavior management by the pediatric dentist easier. It can be used for a variety of procedures which are routinely carried out in a modern dental practice, including a multitude of soft tissue procedures, such as soft tissue surgery, periodontal therapy as well as being an efficient tool for use in implantology, endodontics, and tooth whitening but the lack of knowledge in dentists and price of the laser are the major limitations for its use in clinical practice.
