Evaluation of the Color Change of the Laser and Chemical Vital Whitening Method in the Teeth

Summary

Having an aesthetic smile has become very common among patients today. Recent studies have shown that people aged 18-49 want to have whiter and brighter teeth. The demand for whitening has increased by 300% in the last 5 years. New materials and equipment have been developed to meet this demand, and various whitening techniques have been developed for use at home and in clinical practice. Determination of color in dentistry; It can be divided into two categories with the help of visual and computer-aided devices. Eye color determination is the most widely used method during the construction of a indirect restoration. The evaluation of tooth color by eye is quite subjective. Physiological variables such as external light source, experience, age and human eye fatigue, color blindness cause inadequate results. Due to interpersonal detection differences during color perception, the lack of standardization in the determination of tooth color can be improved with the use of computer-aided devices such as spectroradiometer, spectrophotometer, colorimeter and with the help of film-based photographs and digital photographs. Spectrophotometric approach; the point of view is interesting, as it allows for an objective application, regardless of the practitioner's experience. The color selection made with the use of these devices provides a potential advantage over the color selection made with the eye. Because these measurements are objective, can be counted and can be obtained faster. Although widespread uses of computer aided colorimeters and spectrophotometers have been reported in dental studies, most devices are not suitable for routine clinical use. Color analysis with these computer-aided devices may cause inaccurate results especially in the evaluation of translucent objects such as teeth. Therefore, a combination using both eyes and devices should be used.

Conditions

• Color; Change Teeth, Posteruptive

Interventions

PROCEDURE

Laser Bleaching

Content; There are 35% hydrogen peroxide, potassium nitrate, sodium fluoride, sodium hydroxide, thickener, glycol derivative. The way of application; Gingival protection is applied. The gel is applied to the labial surfaces of the teeth with a thickness of 1-2 mm. The use of laser increases the effectiveness of the gel. Operator and patient use protective glasses during laser application. The gel shows its effectiveness in about eight minutes. Then the gel is removed with the help of saliva absorber. The procedure is repeated until the desired degree of whitening is achieved. Then it is checked with a color scale.

PROCEDURE

Chemical Bleaching

"Total Blanc Office Teeth Whitening System (H35)" will be used as chemical whitening agent. Content; There are 35% hydrogen peroxide, thickener, plant extracts, amide, release agent, glycol, paint and water. Method of Application; Gingival protection is applied. A 1 mm thick layer of gel is applied to all of the labial surfaces of the tooth. The whitening agent remains on the tooth surface for 20 minutes. At the end of this period, the gel is removed with saliva absorber and the surface is cleaned with a moist gauze.
