Evaluation of perception of dental color by students and professors of dentistry

Abstract

AIM: To evaluate visual perception of dental color carried out by students and professors of Dentistry area. MATERIAL AND METHODS: For this study, 64 people were selected to respond a personal questionnaire and a color selection questionnaire. The respondents also perform, using the color scale VITAPAN classical, the choice of healthy human tooth color, maintained humid and in an acrylic resin cylinder developed especially for this research. RESULTS: Only 6.25% of respondents answered correctly the natural tooth color. CONCLUSION: According to the color verification through a spectrophotometer, only 6.25% of respondents have carried out correctly the color selection. In this way, for the good aesthetical result, the criteria need to be standardized and pre-stablished in order to perform the color selection correctly, observing the variables which can interfere on its choice.

Tooth Color as a Predictor of Oral Health‐Related Quality of Life in Young Adults

“…In the literature, a frequently noted factor in this context is tooth color, which can act as a predictor for satisfaction with dentofacial appearance . This aspect can be defined as the psychophysical subjective, individual perception of the individual observer, where the perceived color depends on the object, its surface, and the individual's perception . Illumination also has had an important role when assessing tooth color.…”

Tooth color assessment

“…Kako bi se smanjio problem zbog pojave metamerizma poželjno je koristiti standardne izvore svjetlosti pri postupku određivanja boje zuba. Tako se izbjegava različit stupanj apsorpcije ili refleksije svjetlosti od određenog objekta, a samim time ostvaruju se pogodni uvjeti za korektnu procjenu boje 21 .…”

“…Njihovo korištenje ima brojne prednosti kao što su točnost, ponovljivost, objektivnost, brzina odabira i lakoća reproduciranja boje 11,28,29 . Pomoću uređaja za instrumentalno određivanje boje možemo točno i objektivno odabrati boju, bez obzira o uvjetima u okolini kao što su osvjetljenje, boja zidova ordinacije, bez obzira na promatrača, njegovu dob, treniranost oka, optičke fenomene i ostale fenomene koji se događaju pri gledanju i percepciji boje koji mogu utjecati na naš odabir 2,21,29 . Pomoću spektrofotometra, jednog od najtočnijih uređaja za odabir boje u dentalnoj medicini, boja se određuje tako da se senzor prisloni na zub kojem želimo odrediti boju, a uređaj refleksiju svjetlosti prenosi u električne impulse, te rezultate dobivamo u digitalnom obliku na ekranu.…”
