28 I I industry report _ professional home bleaching satisfied because he expected a more evident ef- fect and did not want to extend the treatment. With regard to motivation, all of them showed a huge satisfaction, especially for how the kit had been introduced, considering it as very inno- vative, handy and with no limits of use. For the result details of this comparative analysis, please see Tables 1 and 2. _Clinical cases The case report in the pictures shows a 30- year-old male with an apparently optimal health condition,whowasunhappywiththediscoloura- tion on the central and upper- and lower-lateral teeth near the cervical area. After an objective ex- amination of the oral cavity, the subject showed a normalgingivalbiotype,goodgingivalhealthand good oral hygiene. For the verification of the ini- tial and final colour (hue and croma) I used the VITA shade guide, starting from A3 (Fig. 2). After a session of professional prophylaxis I proposed to the patient the bleaching treatment Ena White 2.0 and advised him to perform it after his oral hygiene routine in the morning and in the evening. When he realised how easy the system was to use, he immediately accepted the treat- ment that I explained, as shown in the pictures. First of all you show the patient how to open the toothbrush by unscrewing the cap (Fig. 3a). Then the head of the brush must be unscrewed too (Fig. 3b) to remove the seal from the base of the toothbrush (Fig. 3c). After screwing the final partofthetoothbrushonthedispenseragain(Fig. 13d), you must rotate the ring on the base of the toothbrush anti-clockwise towards the direction ‘UP’ until the bleaching gel comes out (Fig. 13e). For the first application, a couple of rotations are required, until the tube is filled up to the bristles. Explain to the patient that for the following ap- plications it will be sufficient to rotate the ring of 2–3 marks to obtain the needed quantity of gel, likeasmalllentil,asshowninthepicture(Fig.13f). Show the patient how to proceed with brushing: make a horizontal movement for about 30 sec- onds (Fig. 13g), avoiding brushing the gums as much as possible; the blunted shape of the bris- tles helps the patient to avoid this contact, which does not cause irritations anyway, considering theshortapplicationperiod.Atthispointitisnec- essary to rinse the toothbrush with water (Fig. 13h) and brush the teeth again for a further 30 seconds (Fig. 13i). In this way the residual gel on the teeth is diluted before the final rinse. You can notice the evolution of the bleaching action in pictures from Fig. 4 to Fig. 11, where you can appreciate the final result of the treatment Fig. 4_Check after 4 days.
