“…Ezz Azzeh, Ezz Azzehand Mehmet Oguz stated that the conversion of laser light to heat can also threaten the vitality of the debonded teeth by damaging the tooth pulp. Selecting the appropriate laser, resin, and bracket combination can minimize risks and make debonding more efficient.Pilot studies and computer modeling suggest that for commonly used polycrystalline brackets debonded with the carbon dioxide laser, some form of mechanical assistance is needed during the lasing process to keep the intrapulpal temperature below the 5.5° C safety threshold [8,15,16].…”

Background: Debonding procedure is time consuming and damaging to the enamel if performed with improper technique. Various debonding methods include: the conventional methods that use pliers or wrenches, an ultrasonic method, electrothermal devices, air pressure impulse devices, diamond burs to grind the brackets off the tooth surface and lasers. Among all these methods, using debonding pliers is most convenient and effective method but has been reported to cause damage to the teeth. Recently, a New Debonding Instrument designed specifically for ceramic and composite brackets has been introduced. As this is a new instrument, little information is available on efficacy of this instrument. The purpose of this study was to evaluate the debonding characteristics of both "the conventional debonding Pliers" and "the New debonding instrument" when removing ceramic, composite and metallic brackets.

Laser-Aided Ceramic Bracket Debonding: A Comprehensive Review

Different techniques have been introduced for the removal of ceramic brackets. Since the early 1990s, lasers have been used experimentally for debonding ceramic brackets. The goal of this study is to give a comprehensive literature review on laser-aided ceramic bracket debonding. PubMed and Google Scholar databases were used to identify dental articles with the following combination of key words: Ceramic brackets, Debonding, and Laser. Sixteen English articles from 2004 to 2015 were selected. The selected studies were categorized according to the variables investigated including the intrapulpal temperature, shear bond strength, debonding time, enamel damage and bracket failure. Most articles reported decreased shear bond strength and debonding time following laser irradiation without any critical and irritating increase in pulpal temperature. There were no reports of bracket failure or enamel damage. Laser irradiation is an efficient way to reduce shear bond strength of ceramic bracket and debonding time. This technique is a safe way for removing ceramic bracket with minimal impact on intrapulpal temperature and enamel surface and it reduces ceramic bracket failure.

Debonding of the ceramic brackets with the aid of laser technology has become a certified technique in the field of orthodontics, as the use of a laser eliminates the problems of debonding that are associated with the traditional method. These problems may include enamel cracking and broken ceramic brackets, as well as the pain experienced by the patient during the removal of ceramic brackets [1]. Moreover, the use of a laser reduced the efforts and time needed for brackets debonding through thermal annealing of orthodontic brackets [2]. However, the effects of different lasers on the teeth and pulp tissue have not been fully determined. AbstractBackground. Deboning of ceramic brackets using a Er:YAG laser has become an acceptable method to facilitate the removal of such type of brackets. Therefore, research has been conducted to establish safer and more effective techniques. The pulse duration is one of the most critical parameters with respect to thermal effect on the pulp vitality. Objectives. The goal of the current research is to evaluate the thermal effect of different Er:YAG laser pulse durations in order to establish safe and effective protocols of debonding ceramic brackets. Material and Methods. The sample consisted of 45 premolars extracted for orthodontic purposes. A ceramic bracket was bonded to each tooth. The sample was divided into three groups: 15 teeth for pulse duration of 50 µs, 15 teeth for pulse duration of 100 µs, and 15 teeth for pulse duration of 300 µs. All the ceramic brackets were exposed to the Er:YAG laser for 6 s by laser scanning method, with the same air and water conditions, as well as the same pulse energy and repetition rate. The tooth temperature was monitored during debonding the brackets by a thermal camera, and the ceramic bracket was debonded after 18 s. Then, the samples were examined under a microscope to evaluate the presence of the adhesive material. Results. The results showed the absence of a statistically significant difference between the pulse duration of 50, 100 and 300 µs in relation to the rise in temperature of the tooth. However, a statistically significant difference was found in relation to the presence of adhesive materials between pulse duration 50 µs and both 100 and 300 µs, with no statistically significant difference between 100 and 300 µs. Conclusions. Within the limits of this study, both Er: YAG pulse durations of 100 and 300 µs are preferred during ceramic brackets debonding using the laser scanning method (Dent. Med. Probl. 2016, 53, 3, 352-357).
