Anodized titanium abutments may improve color in esthetic regions when a ceramic abutment cannot be used. The study showed that the gold-colored titanium produced via anodization was better than other colors at producing a tooth-like color for implant-supported zirconia restorations. Also, by adjusting the color of zirconia restorations, the effect of the background could be altered using the zirconia sintering protocol.

To examine the marginal adaptation in enamel and dentin of mixed Class V saucer shaped restorations where cavities were prepared by two different lasers.

A handpiece-integrated ErYAG laser @ 4.5 W, 300 mJ, 15 Hz (LiteTouch III) and a novel CO2 laser @ 12.95 W, 19.3 mJ, 671 Hz (Solea 9.3 µm). Diamond bur preparation with a 25 µm diamond bur (Intensiv) in a red contra angle at high speed under water spray cooling served as the control. Eight cavities per group were readied and restored under simulation of dentin fluid with a one bottle universal adhesive (One Coat 7 Universal) and a nanohybrid resin composite (Everglow), applied in two layers. For every preparation technique, the adhesive system was applied in the selective-etch and the self-etch mode, resulting in six experimental groups. Marginal analysis was performed immediately after polishing and after simultaneous thermal (5-50°C, 2 minutes each) and mechanical (max. 49 N; 200,000 cycles) loading by using a SEM (x200 magnification).

Significant diftotal marginal adaptation showed results which were comparable to conventional bur preparation with selective-etch technique.
To investigate the effectiveness of different light activation methods for in-office bleaching agents in terms of color change durability and tooth sensitivity (TS).

80 subjects were randomly divided into four groups (n= 20). A bleaching agent (40% H2O2) was activated using a neodymiumyttrium-aluminum-garnet (NdYAG) laser, an 810-nm diode laser, a light-emitting diode (LED), and conventional (chemical) treatment. The CIE L*a*b* system and ΔE* values were used to measure color changes in the teeth using a spectrophotometer. TS was measured using the visual analogue scale (VAS). The measurements were performed before the treatment, immediately afterwards, and 2 weeks, 1 month, and 6 months later. A P< 0.05 was accepted as statistically significant.

The most statistically significant color change occurred in the 2nd week (⏊E2) in all groups (P< 0.05). However, the most color change in the 2nd week (ΔE2) occurred in the NdYAG group, yet there was no statistically significant result between NdYAG and L and cause minimum sensitivity.
To evaluate the efficacy, longevity, and bleaching sensitivity of in-office bleaching with 37% carbamide (CP) and 35% hydrogen peroxides (HP).

45 volunteers were enrolled in this randomized, double blind, controlled, split-mouth clinical trial with a 6-month follow-up. Left and right hemiarches were randomly selected to receive CP or HP in-office bleaching. Three 40-minute applications of both bleaching agents were performed once a week at the same time. Tooth shade and bleaching sensitivity were recorded before and after bleaching sessions, 1 to 7 days after bleaching sessions and up to 6 months after the last bleaching session using, respectively, a shade guide and Visual Analogue Scale (VAS). this website Color change, global immediate sensitivity - GIS (sum of sensitivity levels reported during three bleaching sessions), trans- and post-bleaching sensitivity were obtained and analyzed using paired Student t-test and two-way ANOVA/Tukey post-hoc tests (P< 0.05).

HP had statistically higher global immediate sensitivity than CP. CP showed statistically lower sensitivity levels during bleaching sessions and in two subsequent days than HP. CP and HP provided statistically similar tooth shade at the end of the last bleaching session and 3 and 6 months after the last bleaching session.

In-office tooth bleaching using CP resulted in less bleaching sensitivity than HP, without compromising efficacy and longevity over a 6-month follow-up period. The use of 37% carbamide peroxide in substitution for 35% hydrogen peroxide can promote an effective, long-lasting, and more comfortable in-office tooth bleaching for patients.

To conduct a clinical evaluation of calcium lactate and sodium fluoride mouthrinses in reducing sensitivity and efficacy of color change during in-office bleaching.

75 participants were selected and divided into three groups (n= 25), according to the type of desensitizing treatment tested calcium lactate mouthrinse prior to sodium fluoride mouthrinse before each bleaching session; daily mouthrinse with sodium fluoride; control (absence of mouthrinse). Each mouthrinse was used for 1 minute. Bleaching was performed following the same protocol in all groups, with 40% hydrogen peroxide (Opalescence Boost), in three 40-minute sessions, with a 48-hour interval between sessions. Clinical parameters such as sensitivity, gingival irritation and mouthrinse acceptability were assessed using Visual Analogue Scale (VAS) and clinical examination at two timepoints baseline (before any treatment) and 48 hours after the end of treatment. The color was evaluated with a spectrophotometer (VITA Classical scale guide, 3D Maste prevented its increase.
Although bleaching sensitivity during in-office bleaching treatment cannot be avoided, daily fluoridated mouthrinse or calcium lactate used prior to fluoridated mouthrinse prevented its increase.
