Abstract
Objectives: This study aims to assess the self-perception of female
dental students of their dental aesthetics regarding their satisfaction, its effect
on their quality of life and felt need for treatment.
Materials and Method: This is a descriptive study for 1st, 2nd and 3rd year
dental students (n=110) in the College of Dentistry at Princess Nourah
University (PNU). The survey was distributed via link "Google form". A 20
item questionnaire was prepared and tested before on seven students for
clarity. Questions were regarding how students feel about their dental
aesthetics and what they desire for treatment. Whether they felt their teeth
affected their attractiveness, confidence and quality of life. Data was entered
in SPSS for statistical analysis.
Results: With a response rate of 94.5% majority (89.4%) of students felt
their teeth affected the attractiveness of their faces. Almost one third (30.8%)
have tried to hide their smile. Around half (51%) were not satisfied with their
tooth colour. Almost two thirds of students (61.5%) felt their quality of life is
affected by the appearance of their teeth. ‘Tooth whitening’ was selected by

almost two thirds of students (64.4%) followed by almost half (46.2%) the
students wanting ‘orthodontic treatment’.
Conclusion: Dental aesthetics is rated highly among female dental
students.The majority of the students felt that their teeth affected the
attractiveness of their face and influenced their quality of life. Students
desired teeth whiteneing followed by orthodontic treatment as their
perceived need for aesthetic dental treatments.

Introduction
Dental factors play an important role in the physical perception of an
individual (Lopez 2013). The Face is one of the most important part of the
body to show physical beauty (Subait et al 2016).The dental appearance of
an individual is an important feature in determining the attractiveness of a
face (Qualtrough and Burke 1994) and plays a key role in human social
interactions (Lopez 2013, Kershaw et al 2008, Qualtrough and Burke 1994).
Dental appearance also plays an important role for boosting self-confidence
(Tin-Oo, et al 2011, Manipal 2014). The main determinant factor for
improving dental appearance is a person’s own deisre influencing one’s selfconciousness about their smile, self confidence and self esteem (Yi et al
2016). Perception towards dental appearance is determined by cultural
factors and individual preferences varying between individuals and cultures
and changes over time (Qualtrough and Burke 1994).
The smile plays an important role in the evaluation of facial
attractiveness and in the overall assessment of a smiling person’s
attractiveness (Otta et al 1996). Beall (2007) showed that the smile has a
major impact on the physical attractiveness of the person. Aesthetic dentistry
is characterized primarily by the smile which serves as the primary means of
emotional expression (Talarico 2006). Dentists have cited media coverage as
the main reason for the increase in demand for aesthetic dental procedures
(American Academy of Cosmetic Dentistry 2004). Among the significant
factors affecting overall dental appearance are tooth colour, shape, and
position; quality of restoration; and the general arrangement of the dentition,
especially of the anterior teeth (Qualtrough and Burke 1994) with tooth
colour being one of the most important factors determining satisfaction with
dental appearance (Qualtrough and Burke 1994, Van der Geld et al 2007).
Treatments improving dental aesthetics have been found to increase
patient quality of life and psychological status (Al-Zarea 2013, Grossmann et
al 2007, John et al 2004,). Tooth whitening treatments, anterior teeth
restoration, labial veneers crowns, and orthodontic treatment are frequently
172

demanded by patients who are interested in improving their dental
appearance (Samorodnitzky-Naveh et al 2007). Manipal et al (2014) found in
their study on dental students that with respect to psychological aspects,
mental depression shows more significance as students feel more deprived
due to their unaesthetic appearance. Nazir et al (2014) assessed the
psychosocial impact of dental aesthetics and self-perceived orthodontic
treatment in dental students showed a strong association between subjects
perceiving the need for orthodontic treatment and their psychosocial
wellbeing.
There have been very few studies in Saudi Arabia to document dental
students perception of dental esthetics. (Al-Zarea 2013, Al Shahrani 2014,
Bilal.R & Subait et al 2016). Therefore the aim of this study is to assess the
self-perception of female dental students of their dental aesthetics regarding
their satisfaction, its effect on their quality of life and felt need for treatment.
Materials and Method
This was a descriptive study conducted in College of Dentistry,
Princess Nourah University (PNU), Riyadh, Saudi Arabia. The study
population consisted of all the female students (n= 110) studying in the
Dental College at the time of the study with first (n=44), second (n=35) and
third (n=31) year female dental students only. Prior approval was obtained
from the Institutional Review Board, College of Dentistry, PNU. The ages of
students ranged from 17-22 years in all classes from first to third year dental
students D-1, D-2, D-3 respectively. A modified 20 item close ended
questionnaire was constructed after taking some questions used in Tin-Oo
study (2011) and adding more questions in it . The questions in Table 1,2 and
3 were mainly regarding students' satisfaction with their dental aesthetic
appearance, whether they felt their teeth affected their attractiveness,
confidence and quality of life and the desired aesthetic dental treatment they
wish to have. It was tested on 7 students randomly before the start of the
study to check if it was clear and then corrections were made accordingly.
The questionnaire was then distributed via link "Google form" to all the
students (n= 110) with a short explanation of the study and their answering
the questionnaire was taken as their consent. An Ivostar® Gnathostar® shade
guide image by Ivoclar Vivadent. Inc. was incorporated within the
questionnaire regarding the preferred shade selection by the students.
Choices with shade number from lightest to darkest were given for the
answers in the drop down answer options menu. Students picked the tooth
shade option they would like to have. Statistical analysis using SPSS was
done for percentages.

Results
The response rate was high (94.5%) as the questionnaire was
completed by 104 female dental students from a total of 110 targeted for the
study from the Dental College, PNU at the end of the academic year of 2015.
Dental students’ self-evaluation of their dental aesthetics in Table
1 shows almost two thirds (62.5%) of students felt they had an attractive
face. The majority (89.4%) felt their teeth affected the attractiveness of their
faces. Around three-quarters (76%) were satisfied with the way their gums
look. Just over half (57.7%) were satisfied with the general appearance of
their teeth. Around half (51%) were not satisfied with their tooth colour.
Around one quarter (26.9%) felt their teeth were crowded or poorly aligned.
Non aesthetic restoration in their front teeth was reported by 15.4% of
students. A fractured front tooth was reported by 9.6%. Tooth wear was
reported in 19.2% of students.

person’s face? (Figure 1). Just over half (56.7%) answered ‘teeth and gums’
followed by ‘look at the face in general’ by 26.9%.
Three quarters (71.2%) of students reported looking at teeth of
celebrities in social media and wishing to have pretty smiles like them.

Discussion
In our modern society dental appearance is an important feature in
determining the attractiveness of a face and plays a key role in human social
interaction (Tin-Oo, Saddki and Hassan 2011). In this study almost all the
students agreed that at the present time in Saudi Arabia people consider
dental aesthetics more important than they did 10-15 years ago. They also
felt that dental aesthetics is important for their quality of life. Almost twothirds of students felt their quality of life is affected by the appearance of
their teeth whereas in Manipal et al (2014) study in India dental students
reported a much lower percentage (19.5%) for females. These differences
may be due to cultural, religious or racial factors (Tin-Oo, Saddki and
Hassan 2011, Al-Zarea 2013).
It was also found in this study that students reported having enough
knowledge of the available aesthetic dental treatment options. Al-Shaharani
(2014) quoted that dental students become more aware of dental aesthetics
during their education and this can affect their perception of facial
attractiveness. Bilal (2016) also showed that as the dental students
progressed to senior years they became more aware of their own dental
esthetics owing to critically aprasing themselves with their increased dental
knowledge. Just over half of the students in this study reported that when
looking at a face of a person for the first time they look first at the teeth and
gums rather than the other parts of the face like the lips, eyes, nose or face in
general. This suggests these students place great importance to a person’s
dental aesthetics.
Almost two thirds of students in this study felt they had an attractive
smile and a great majority of students felt their teeth affected the
attractiveness of their face which implies teeth are very important for them to
feel attractive. Around two-thirds of students felt confident about their smile
however almost a third reported they try to hide their smile. Manipal et al
(2014) showed a higher percentage (86.2%) of females were satisfied with
their smile. As for non-aesthetic restorations both this and Al-Zarea (2013)
study had similar results for students reporting of having a non-aesthetic
restoration in their front teeth (15.4% and 16.4% respectively).
Almost a third of our students were not satisfied with the general
appearance of their teeth. A higher percentage (50%) of university students
(including dental students) were found not to be satisfied as Al-Zarea
reported in 2013, along with Tin-Oo, Saddki and Hassan (2011) showing
similar results (52.8%). The differences found in these studies may be due to
use of different measures to evaluate satisfaction, cultural factors, religion,
and racial factors as well as dental appearance is affected by individual
characteristics, compliance, or unrealistic expectations (Al-Zarea 2013).
178
European Scientific Journal January 2017 edition vol.13, No.3 ISSN: 1857 – 7881 (Print) e - ISSN 1857- 7431
When students were asked about the choice of restorative dental
material for a posterior tooth almost three-quarters reported they preferred
having composite restorations rather than amalgam although amalgam is
considered a stronger dental material for posterior teeth. This again suggests
that students care a lot about how teeth look aesthetically. As for tooth
whitening it was strongly desired in this study and almost two thirds of
students wanted it. Similar results were shown by Subait et al (2016), yet this
is less than what was reported by Al-Zarea (2013) and Bilal (2016) where it
was wanted by a higher majority (80.9% and 87.9% respectively).
As for the their satisfaction with colour of their teeth only 38.4% of
the students were satisfied with the colour of their teeth which is similar
(34.1%) to Al-Zarea (2013) study of university students in Saudi Arabia and
Tin-Oo, Saddki and Hassan (2011) study in Malaysia that also reported
similar results (43.8%). However in the study of Manipal et al (2014) in
India it was reported that the majority (86.2%) of females were satisfied with
the colour of their teeth. Again these differences may be due to the fact that
dental appearance is affected by individual characteristics, compliance, or
unrealistic expectations (Al-Zarea 2013).
The majority of students in this study desired tooth shade guide
colours lighter than the natural colours of A1 and B1 as their preference for
tooth whitening. This could be due to the effect of the media of exaggerating
the whiteness of teeth and making it attractive and appealing to the public.
Again this is emphasized in this study where almost three-quarters of
students look at teeth of celebrities in the media and wished they had smiles
like them. These celebrities usually have very white and straight teeth.
Besides these students wanting white teeth they also wanted straight teeth.
Almost half the students wanted orthodontic treatment which was similar to
Al-Zarea (2013) study (51.8%). Just over one-quarter (26.9%) of our
students felt their teeth were crowded or poorly aligned which was similar to
that found by Al-Zarea (2013) where one quarter reported crowding. TinOo, Saddki and Hassan (2011) also reported similar results (26.4%) for
crowding.
Conclusion
Dental aesthetics is rated highly among female dental students. Just
under half the students were not satisfied with the general appearance of their
teeth and around half were not satisfied with their tooth colour. The majority
of the students felt that their teeth affected the attractiveness of their face and
influenced their quality of life. Majority of students also wished they had
smiles like celebrities. Students desired teeth whitening followed by
orthodontic treatment as their perceived need for aesthetic dental treatments
