简要总结

Compare by clinical observation, photographs and fluorescence the efficacy of sodium fluoride, silanofluoride and thiefenfluoride in treating white spots.

详细描述

This in vivo study will be a randomized experimental clinical trial to be carried out in the Department of Pediatric Dentistry of the International University of Catalonia. Patients between the ages of 3 and 12, who attend the dental university clinic of the International University of Catalonia, will be part of the study.

Parents or legal guardians will be informed of the treatment procedure with a patient information sheet and informed consent will be given. Once signed, the patient will be assigned to one of the 3 study groups.

Accepting an alpha risk of 5% and with a power of 80% in a bilateral contrast, 15 subjects in each group are required to detect a minimum difference of 4 points between two groups, assuming that there are 3 groups and a standard deviation of 4.9. a follow- up loss rate of 10% has been estimated. The total number of children will be 45 by 15 for each group.

In order to analyze the degree of agreement of one examiner, 15 children will be evaluated twice, with a separation of one month.

结局指标

主要结局

tactile examination

时间窗: 6 MONTHS

Tactile examination. An exploratory probe will be used by moving it over the examination surfaces without applying pressure. The data will be recorded as follows: 1. Smooth surface, 2 Rough surface, based on a modification of the criteria of Ekstrand et al.

fluorescence

时间窗: 6 MONTHS

Using the quantitative light fluorescence method using a VistaProof device (Dürr Dental), the use of which significantly improves the quality of the diagnoses. The results will be evaluated by recording the indications of fluorescence intensity before and after treatment. The fluorescence chamber will be positioned up, parallel to the buccal / buccal surface. The software (DBSWIN, Dürr Dental) will digitize the video signal to create buccal / buccal surface images of 720 × 576 pixels with 3 × 8 bit RGB channel intensities and a resolution of 72 pixels / inch14,15. This software will quantify the fluorescence emitted from green (wavelength of approximately 510 nm) to red (wavelength of approximately 680 nm), and will assign a numerical value of 0 to 3, which corresponds to the severity of the injury according to the manufacturer's instructions.

photography

时间窗: 6 MONTHS

Photography. To standardize photographic conditions, the camera will always be placed at the same distance from the tooth surface. To exclude the influence of moisture on the tooth color, the tooth surfaces will be dried with compressed air for 30s. Clinical photographs will be taken with a digital camera (EOS 5d Mark II camera; Canon, Tokyo, Japan), macro lenses (SP AF100 mm F ⁄ 2.8 Di 1: 1 Macro lenses; Canon, Tokyo, Japan) and flash (MT Twinlight 24- EX; Canon). The camera settings will be as follows: shutter speed 1 ⁄ 125, F29, ISO 200 and automatic white balance. The photographic evaluation will be carried out by the same examiner; Photographs will be randomly designated to avoid measurement bias and will be measured using the L \* a \* b \* scoring method of the Commission Internationale de l'E 'clairage.

visual examination,

时间窗: 6 MONTHS

Clinical examination, using ICDAS criteria for the visual diagnosis of caries. The visual inspection will be carried out using the ICDAS criteria. Selected sites will be examined with direct visualization under light illumination and a three-in-one air syringe, without probing. Wet teeth will be evaluated first, and then dried after 5 s. Visual examination will be coded as follows: (0) healthy tooth surfaces, with no evidence of caries after prolonged air drying (5 s); (1) white or brown stain visible on dry enamel; (2) white or brown stain visible on wet enamel. Teeth with codes from 0 to 2 will be included in the study.
