Sir,

In the ugly duckling stage, the teeth will have a physiological mobility due to the lack of complete root; whereas in adults, the tooth mobility may be associated with changes that occur during orthodontic tooth movement. In either case, iatrogenic avulsion may happen if proper care has not been taken during the intubation or application of teeth retaining retractors. The use of mouth guard appliance during anesthesia for the patient is essential to prevent iatrogenic avulsion of teeth during any intraoral procedures such as tonsillectomy and cleft palate repair procedures. Recently, Gaudio et al. reported that in intubation procedures without using the protective devices dental subluxation/luxation occurred in 55% of patients, dental avulsion in 43%, and exfoliation in 2%. [1] Hence, the surgeons who do endoscopy under general anesthesia should have a comprehensive awareness of root formation of teeth.

Accidental intraoperative avulsion of teeth is common in intraoral procedures, with teeth retaining retractors, which are performed in maxillofacial, otolaryngology, and anesthesia. [2] Minimizing dental injuries begin with the assessment of the patient's dentition and intraoral tissues. Bak has recently reported a case of accidental tooth avulsion during tonsillectomy. [3] The upper left incisors were involved most frequently at the time of tracheal intubation. [4] Therefore, intraoral instrumentation for procedures associated with the application of tooth attached retractors often gives adequate access to the surgical field as well as keeps the tongue out of the working field [Figure 1]. Exercising cautionary measures during events, such as laryngoscopy and tracheal extubation, can aid in the prevention of dental trauma. Apart from all these precautions, any mishaps such as slipping of retractors can occur during the procedures, and an iatrogenic injury may dislodge the vulnerable tooth. [5] This can be prevented by placing a flexible, thin, and easily placed mouth guard appliance, on the teeth, during the procedure [Figure 2]. The patients with mouth guards had significantly lower incidence of dental injury compared with those without mouth guards (0.06% vs. 0.37%). [4] Apart from its therapeutic purposes, the mouth guards are commonly used by patients with a habit of bruxism. Mouth guards are made of a heat-cured acrylic resin. Soft acrylic or light cured composite, or vinyl splints may be made more quickly and cheaply, but are not as durable and are more commonly made for short-term use. They generally cover all the teeth of the upper or lower arch. Soft splints are also used for children. The mouth guard appliance can be placed safely during the procedure in maxillofacial, otolaryngology, and anesthesia to prevent the injuries to teeth.
