6 General bleaching procedure 6.1 Preparations 6 General bleaching procedure 6.1 Preparations 6.1.1 Select the bleaching gel The bleaching effect and possible side-effects depend on the selected bleaching gel and the teeth that are treated. Consult the manufacturer's information for the bleaching gel for instructions CAUTION Increasing the output setting This can cause hyperthermia in the pulp. Do not perform bleaching at a higher output. KaVo accepts no liability for damage arising from the bleaching procedure. Important factors for selecting the bleaching gel: The bleaching gel must be suitable for use with the GENTLEray 980 diode laser at a wavelength of 980 nm (see manufacturer's instructions concerning the bleaching gel). 6.1.2 Preparing the teeth Requirement The teeth must be carefully cleaned for bleaching to be successful (the plaque and residue must be completely removed). Clean with pumice. Do not use polishing pastes since they contain oil. Follow the bleaching gel manufacturer's instructions exactly. 24/27
6 General bleaching procedure 6.2 Bleaching 6.2 Bleaching The general bleaching procedure with the bleaching handpiece 982 will be describe in the following section. These instructions can vary depending on the bleaching gel. The instructions of the bleaching manufacturer are authoritative when in doubt (see the safety data sheet). Identify the tooth discoloration. This can be done using colour gradation or digitally with suitable software. All of the people in the room must wear the provided protective goggles. Apply gingiva protector and let it harden. 25/27
6 General bleaching procedure 6.2 Bleaching Apply bleaching gel. First apply the bleaching gel on the upper or lower front teeth. Remove any bubbles in the gel when applying the bleaching gel. With multicomponent bleaching gels, following the manufacturer's instructions for use. To activate to the bleaching gel, each tooth must be irradiated for a maximum of 30 seconds. Settings of 1 W to 1.6 W are usual; this depends on the bleaching gel used and must be agreed with the manufacturer of the bleaching gel. These parameters are already preset when selecting the indication "Bleaching (single tooth)" in the indication menu of the GENTLEray 980. Depending on the software version for the GENTLEray 980, the set output can vary. Comply with the manufacturer's instructions for using the bleaching gel, failing which use a maximum output of 1.6 W. The beam diameter is about 5 mm. A distance between the tooth and instrument of 3 cm to 8 cm is recommended. The output of the laser beam remains about the same in this region and enables the best bleaching. The suction off the gel, carefully rinse and dry. Compare the tooth brightness and repeat if necessary. Depending on the bleaching gel, the process should be performed three to four times a session. Depending on the bleaching gel, two to three sessions are required (at least one week apart). The maximum total exposure time for the bleaching gel should be 15 minutes hen not otherwise indicated by the gel manufacturer. Remove the gingiva protector and apply fluoride gel. Irradiate each tooth with 1 W for 10 seconds. 26/27
6 General bleaching procedure 6.2 Bleaching Record the initial status and end result with pictures to clarify and confirm the success of the treatment. These parameters are already preset when selecting the indication "Bleaching (fluoridation)" in the indication menu of the GENTLEray 980. 27/27
