Psihološke dimenzije u procjeni kvalitete života povezane s dentalnom estetikom
Ciljevi istraživanja su slijedeći : prevesti i testirati pouzdanost Upitnika psihosocijalnog
utjecaja dentalne estetike (PIDAQ) i Upitnika oralnog utjecaja na dnevne aktivnosti (OIDP);
istražiti povezanost između dobi, spola, stupnja stručne spreme, parodontološkog i dentalnog
statusa te stupnja pacijentova zadovoljstva izgledom, bojom i položajem zuba te izgledom
zubnog mesa; usporediti pacijentov dojam izgleda gornjih prednjih zuba i zubnog mesa s
kliničkim pregledom doktora dentalne medicine; utvrditi koliko su želje pacijenata u smislu
poboljšanja izgleda povezane sa stvarnim stanjem parodontološkog i dentalnog statusa (boja,
oblik, kompresija, vidljivost); utvrditi koliko su svi dosadašnji dentalni zahvati povezani s
pacijentovim zadovoljstvom izgledom zuba te ispitati koji su od svih izmjerenih parametara
(boja, oblik, veličina zuba, vidljivost...) značajni prediktori pacijentova zadovoljstva izgledom

The psychological dimension in the quality of life assessment in association with dental
The purpose of this study was to translate and test the reliability and validity of the PIDAQ
and OIDP questionnaires; to explore the relationship between age, gender, education level,
periodontal and dental status, and degree of patient satisfaction with appearance, color and
position of the teeth and gingival tissue; to compare the patient's impression of maxillary
anterior teeth and gingival tissue appearance with clinical examination for dentists; to
determine how the patients’ desires matched the actual state of periodontal and dental status
(color, shape, compression, visibility) in terms of improving the appearance; to determine
how all previous dental procedures associated with patient satisfaction of tooth appearance; to
examine which of the measured parameters (color, shape, tooth size, visibility ...) were
significant predictors of patient satisfaction regarding the tooth appearance, as well as to
examine which of the psychological, social and functional dimensions mostly discriminated
the people who are happy with their dental aesthetics from the dissatisfied ones.
Patients and Methods
The sample consisted of 700 participants of both genders who were scheduled for dental
treatment at the Clinic of Dental Medicine, Clinical Hospital Center Rijeka. The study
consisted of completion of the Aesthetic questionnaire specially constructed for this purpose,
as well as completion of two psychological measuring instruments - (Psychosocial Impact of
Dental Aesthetic Questionnaire - PIDAQ) and (Oral Impact on Daily Performances - OIDP ).
The hypothesis was confirmed. Participants who wanted a fixed prosthetic appliances on the
front teeth were significantly older (M = 48.24 years) compared to those who did not want
them (M = 43.63 years, p = 0.001). Factor analysis of the Aesthetic questionnaire indicated
that the assessment scale created for this purpose and based on an assessment of the five
elements of satisfaction was one-dimensional, e.g. it measured the overall level of
satisfaction. Reliability of such scale defined by internal consistency was high (Cronbach α =
Pearson correlation indicated that there was no statistically significant correlation between
age and patients’ satisfaction with their teeth regarding either the individual aspects or the
general level of satisfaction. There are statistically significant effects of tone and intensity of
color, and border interactions and color tone and intensity to the satisfaction of the color of
teeth. The participants with darker teeth give lower estimates of satisfaction teeth.
Negative predictors of the overall satisfaction with tooth appearance were plaque index and
tooth fracture, in contrast to the tooth visibility when smiling which was proven as the
satisfaction predictor of tooth appearance.
The most common dental procedures performed in the investigated population were
professional tooth cleaning and root canal treatment; the fewest had dental implants or
undertook tooth whitening procedures. Subjects with composite fillings commonly expressed
the desire for general improvement in tooth appearance, orthodontic therapy, placement of
crowns and tooth whitening.
Factor analysis of the PIDAQ instrument indicated that factors 2, 3 and 4 which correspond to
the Psychological impact of dental aesthetics, Social impact of dental aesthetics and Dental
self-confidence have sufficient confidence of the average correlation coefficient (r = 0.56-
0.76) and coefficient of internal consistency (α Cronbach 0.88-0.95), while the first factor
(dimension of aesthetic concern) had a low average correlation and internal consistency (r =
0.32 and α = 0.58). Particles of the OIDP questionnaires showed high internal consistency
reliability (Cronbach α = 0.79), and the average correlation between the particles was 0.36
(from 0.16 to 0.84).
We performed a regression analysis to examine the extent to which the results of the PIDAQ
and OIDP questionnaires affected the overall satisfaction with dental aesthetics, but we can
say that the deciding factor of the PIDAQ and OIDP questionnaires does not predict the
patients’ satisfaction with tooth appearance (F5, 531 = 0.43, p =0.82).
Aesthetic questionnaire specifically designed for this study showed an extremely high degree
of consistency (Cronbach α = 0.86), which gives us the possibility to register the same quality
level as the readout in future scientific research.
Patient satisfaction with tooth appearance is associated with the visibility, color and shape of
the teeth, level of education, amount of plaque on the teeth, the presence of fractures of the
teeth and some dental surgery in the anterior segment.
The procedure most frequently desired by the patients was tooth whitening.
Furthermore, the research confirmed the hypothesis that the older participants preferred fixed
prosthetic works unlike the younger ones who were satisfied with composite fillings.
We validated the reliability of the PIDAQ and OIDP instruments, whereby we came to the
conclusion that in the Croatian language the 4 dimensions of the PIDAQ instrument would
probably be better interpreted if reduced to two dimensions, with the Aesthetic concerns
posing as one dimension, and the remaining three should be consolidated into the second
dimension. OIDP questionnaire also had a high degree of consistency (Cronbach α =0.79)
