REVIEW ARTICLE
Supernumerary teeth: A review on a critical endodontic challenge
Hany Mohamed Aly Ahmed, Jojo Kottoor, Ahmed Abdel Rahman Hashem
January-April 2018, 7(1):1-6
DOI

Supernumerary teeth are developmental anomalies that might require endodontic treatment for functional and/or esthetic reasons. A review of literature was conducted using appropriate key words (“Supernumerary” OR “Supplemental” OR “Rudimentary” AND “Tooth,” “Mesiodens” OR “Paramolar” OR “Distomolar”) in major endodontic journals (Australian Endodontic Journal, Dental Traumatology, International Endodontic Journal, Journal of Endodontics, and Oral Surgery, Oral Medicine, Oral Pathology) to identify available reports describing the clinical and radiographic landmarks of different forms of supernumerary teeth and discussing the implications of such anatomical variation on root canal treatment procedures. In addition, this article highlights the potential indications of supernumerary teeth for intentional replantation and autotransplantation treatment procedures.

CASE REPORT
Open bite, root resorptions, midline deviation, and bilateral crossbite malocclusion
Oscar Mario Antelo, Thiago Martins Meira, Laís Cristina Giacobbo, Ariel Adriano Reyes Pacheco, Orlando Motohiro Tanaka

There has been a progressive increase in demand for orthodontic treatment for adult patients. A 40-year-old female came to the orthodontic clinic complaining of overcrowding and midline deviation. Clinical examination showed facial asymmetry and midline deviation due to the extraction of the maxillary and mandibular first premolars of the right side. A periapical radiograph showed a severe root resorption in the maxillary central and lateral incisors. The treatment objectives were to correct the midline deviation, close the open bite, correct the bilateral posterior crossbite, and obtain a Class I relationship for the molars and canines on both sides. This case report shows a treatment approach that was effective in correcting all problems of malocclusion that the adult patient presented. The treatment results have established a new functional and stable occlusion with improvement of facial esthetics, and the roots were no shorter than before treatment.

ORIGINAL ARTICLES
Self-reported differences in oral health attitudes and behaviors of health-care students at a University in Malaysia
Jia Ven Ng, Tahir Yusuf Noorani, Nik Rozainah Nik Abdul Ghani, Imran Alam Moheet
January-April 2018, 7(1):7-13
DOI
:10.4103/ejgd.ejgd_85_17
Background:
Oral health is a vital part of general health. An individual's perception on oral health is reflected by their oral health attitudes and behaviors.
Aim:
To determine and compare the oral health attitudes and behaviors of dental, medical, and nursing students at Universiti Sains Malaysia (USM).
Methods:
A modified version of Hiroshima University– Dental Behavioural Inventory (HU-DBI)-based questionnaire consisting of 20 items was distributed to all health-care students (
n
= 1166) of USM. HU-DBI score was calculated using responses to 12 HU-DBI items in the questionnaire. HU-DBI scores of the three groups were compared using one-way ANOVA complemented by Bonferroni test. Scores among preclinical and clinical levels were compared using independent
t
-test. Chi-square test was used to evaluate the differences in distribution of all items in the HU-DBI survey.
Results:
Dental students had the highest mean HU-DBI score (7.79 ± 1.58), followed by their nursing (6.99 ± 1.46) and medical (6.42 ± 1.58) counterparts. The mean HU-DBI score for all clinical students (7.04 ± 1.75) was significantly higher than those in their preclinical years (6.64 ± 1.56). Among the 12 HU-DBI items that were used to calculate the HU-DBI scores, items 2, 6, 8, 9, 10, 15, 16 and 19 show significant difference between the distributions of responses within the 3 groups (
P
< 0.05).
Conclusion:
Dental students demonstrated better oral health attitudes. However, all our future health-care provider needs to have better attitudes toward oral health. Hence, comprehensive oral health awareness programs need to be incorporated to all health-care students throughout their study programs.

Evaluation of the bonding strength between yttrium-stabilized zirconia and coating ceramics with three-point flexural Test: The surface treatment effect
Anderson Fernandes Felipe, Walace Henry Miranda Coimbra, Geraldo Alberto Pinheiro Carvalho, Simone Kreve, Aline Batista Gonçalves Franco, Sergio Cândido Dias
January-April 2018, 7(1):14-18
DOI
:10.4103/ejgd.ejgd_100_17
Aim:
This study aimed at evaluating with the three-point flexural test, the bonding strength of tetragonal zirconia polycrystalline stabilized by yttria zirkonzahn (Y-TZP) and two coating ceramics (Ice e Vision Zircon), with two surface treatments (treated and untreated).
Materials and Methods:
Forty Y-TZP bars were divided into four groups (
n
= 10): vision zircon/without treatment (VZ/woT), vision zircon/with treatment (VZ/wT), ice/without treatment, and ice/with treatment (I/wT). The flexural strength assay was conducted using a 50 N load cell and 1 mm/min speed. Results were analyzed with one-factor ANOVA, two-factor ANOVA, and Tukey's test (α = 0.05).
Results:
The treatment surface of Y-TZP affected significantly the bonding strength (
P
= 0.019), with higher values in VZ/woT group in comparison with the groups VZ/wT (
P
= 0.027) e I/wT (
P
= 0.034). The variable “coating ceramic” was not statistically significant (
P
= 0.138), on the other hand, the variable “surface treatment” significantly decreased the strength values when vision zircon ceramics was used (
P
= 0.018).
Conclusion:
This study concluded that the use of the evaluated ceramics did not influence the bond strength and the surface treatment decreased strength depending on the coating ceramics.
