Micro-computed tomography or micro-CT is the non-destructive x-ray imaging of objects which provides a three-
dimensional (3D) view. The working principle is same as the one utilized in hospital CT scans, but on a very small scale. Many companies have even developed nano-CT with submicron spatial resolution. Micro-CT also known as high resolution imaging, does not require preparation of specimens, staining, or slicing. Recently micro-CT has become an integral part of research laboratories in academia as well as in commercial industries.
Micro-CT allows scanning of objects rotated through multiple directions (up to 360° rotation) using microfocal spot X-ray sources and high resolution detectors. Imaging softwares developed along with micro-CT provide 3D reconstruction of images and analyses at different levels. A major advantage of micro-CT is its non-destructive process. Once a specimen is scanned, internal features can be analyzed immediately as many times as needed and the specimen is still available for further testing and analyses. In dental research, micro-CT has gained popularity in recent years and a wide range of specimens such as teeth, bone, biomaterial scaffolds, dental materials (ceramics, polymers etc.), in-vivo small animals can be examined.
This paragraph gives a brief overview of the possible applications of micro-CT in dental research. This is neither an exhaustive list nor the limitations to applications of micro-CT. 1) Using micro-CT it is possible to determine the mineral concentration in enamel and dentin of deciduous and permanent teeth. It can be utilized in de- and remineralization studies of enamel. It is possible to calculate lost and regained amount of mineral content. 2) In endodontics, micro-CT can be used to examine the inner structures of teeth; perform qualitative and quantitative analyses of pulp cavities and root canal morphologies; evaluate root canal preparations and root fillings etc. 3) Using micro-CT a much more precise finite element model (FEM) of teeth and bones can be developed. This 3D model can be used to determine the influence of different techniques of cavity preparation, endodontic access and restorations on the stress distribution in teeth and supporting structures in restorative dentistry. 4) Micro-CT has proven to an extremely useful tool in tissue engineering particularly in the study of scaffolds and bone. It can be used for the characterization of scaffolds and in vitro evaluation of degradation and bone growth. Even the ability of bone substitute materials or different osteogenic cells can be compared in live animal models such as mouse. Non-destructive nature of micro-CT scanning process and absence of specimen preparation step, enables scanning of live animal at different time intervals to evaluate the bone healing or repair. 5) Micro-CT enables precise measurement of trabecular and cortical bone and this can be used to analyze the osseointegration in implant dentistry. Micro-CT can provide qualitative and quantitative measurement of bone integration at the implant surface up to few microns.
Research laboratory of the College of Dentistry has state of the art Micro-CT scanner. A number of research projects are currently running and most of them are related to a particular area of dentistry. Given the quality of the micro-CT scanner and its endless potential, other fields of dentistry should develop collaborative research projects and avail this opportunity to its maximum.

Canal Morphology of Mandibular First Premolars in an Emirati Population. Med Princ Pract. 2017;26(2):118-124.
Indexing Status: Scopus: Web of Science: PubMed:
Abstract
OBJECTIVE: To investigate variations in the root canal morphology of mandibular first premolars in a population
from the United Arab Emirates using micro-computed tomography (micro-CT) and conventional radiography.
MATERIALS AND METHODS: Three-dimensional images of 50 extracted human mandibular first premolars were
produced using a micro-CT scanner, and conventional radiography was also used to record the number of roots,
the root canal system configuration, the presence of a C-shaped canal system and lateral canals, intercanal
communications, and the number and location of apical foramina. The interpretations of micro-CT and
conventional radiography were statistically analyzed using Fisher's exact test. RESULTS: Variable root canal
configurations based on Vertucci's classification were observed in the teeth (i.e., types I, III, IV, V, and VII). The
examined teeth exhibited the following 2 additional root canal configurations, which did not fit Vertucci's
classification: type 1-2-3 and type 1-3. A C-shaped canal configuration was present in 14 (28%) cases, and lateral
canals were present in 22 (44%) cases. Apical deltas were found in 25 (50%) cases, intercanal communications
were seen in 6 (12%) cases, and apical loops were seen in 2 (4%) of the samples. Micro-CT and X-ray imaging
identified 39 (78%) and 34 (68%) apical foramina, respectively. A single apical foramen was detected in 33 (66%)
samples, and 2 or 3 apical foramina were detected in 14 (28 %) and 3 (6%) samples, respectively. In 18.5 (37%)
samples the apical foramina were located centrally, and in 31 (62%) they were located laterally. CONCLUSION: A complex morphology of the mandibular first premolars was observed with a high prevalence of multiple root canal
systems.

Professionalism is a belief system about perfection in health care delivery while ethics is the study of moral
decisions and behaviours. In hidden curriculum, students learn by watching their instructors, but it leaves a lot to
chance to grasp essence of professionalism and ethics. This curriculum is introduced to empower hidden
curriculum and to develop a professionally sound graduate. The curriculum is divided into preclinical phase and
clinical phase. Interactive lectures, case-based learning, self-directed learning and video cases/clips are going to be
used in curriculum delivery. Various assessment methods will be used, either formative/internal assessment or
summative assessment. With the course content, objectives, competencies, teaching learning tools and assessment
tools having been outlined in this document, it is presumed that medical colleges in Egypt under the guidance of
the regulatory body will find it much easier to introduce and implement professionalism and ethics module in
declared curriculum, and we will encounter more professional physicians who are ethically strong.

Abstract
Macroscopic anatomy (gross anatomy) is the examination of human body parts merely using eyesight. Several methods were developed to deliver the scientific facts to healthcare students. Dissection of cadaver is one of the oldest methods. But due to lack of resources, previously prepared (dissected) cadaveric parts are delivered to the students during practical lessons, which are called prosection. In last few years, an innovative method emerges, which is now widely used in universities, i.e. virtual anatomy. The current debates about the use of cadaveric dissection and prosection versus the use of virtual anatomy software is the initiative to write this article. The author hopes that, at the end of reading, the reader come to a definite conclusion about the using virtual anatomy in teaching. 4.

Acta Odontol Scand. 2017;75(2):137-143. Indexing Status: Scopus: Web of Science: PubMed:
Abstract OBJECTIVE: The objective of this study is to investigate the association between oral health practices and similar practices adopted by parents, close friends and classmates in a group of Saudi male teenagers. MATERIAL AND METHODS: A cross-sectional study was conducted in Dammam, Saudi Arabia, in 2016 including 12-14-year-old intermediate school students (n = 478). A questionnaire assessed socioeconomic background, whether participants, their parents, close friends and classmates brushed twice daily, used tobacco, snacked on sugary foods or sugary drinks and perceiving a supportive classroom environment. Univariate and multivariate logistic regression models assessed the association of parents', close friends', classmates' practices and classroom support with participants' four practices, controlling for socioeconomic factors. RESULTS: The response rate was 93.9%. In multivariate regression, close friends' practices had a strong significant association with teenagers' tooth brushing (OR = 4.45; 95%CI = 1.09, 18.12), tobacco use (OR = 5.63; 95%CI = 3.44, 7.88), snacking on sugary foods (OR = 14.42; 95%CI = 7.89, 21.89) and sugary drinks (OR = 7.05; 95%CI = 5.97, 9.20). The percentages of classmates perceived to brush their teeth and use tobacco were significantly associated with the respective practices in teenagers (OR = 1.03 and 1.02). Fathers' snacking on sugary drinks was significantly associated with that of the teenagers (OR = 4.04; 95%CI= 1.03, 15.85). CONCLUSIONS: In early adolescence, four oral health practices of Saudi males were associated with those perceived to be adopted by their close friends. Fathers' use of sugary drinks was also significantly associated with that of teenagers. 5. Majeed A, AlShwaimi E. Push-Out Bond Strength and Surface Microhardness of Calcium Silicate-Based
Biomaterials: An in vitro Study. Med Princ Pract. 2017;26(2):139-145.
Indexing Status: Scopus Web of Science: PubMed:
Abstract
OBJECTIVE: This was an in vitro evaluation of push-out bond strength and surface microhardness of calcium silicate-
based biomaterials in coronal and apical root dentin. MATERIALS AND METHODS: Ninety sections (2 mm thick) of
coronal and apical root dentin were obtained from roots of 60 extracted teeth; the canals were enlarged to a
standardized cavity diameter of 1.3 mm. Sections were randomly divided into 6 groups (n = 15 per group), and cavities
were filled with Biodentine™, BioAggregate, or ProRoot mineral trioxide aggregate (MTA), according to the manufacturers' instructions. Push-out bond strength values were measured using a universal testing machine under a
compressive load at a speed of 1 mm/min. Samples were analyzed under a light microscope to determine the nature of
bond failure. Ten samples (2 mm thick) were prepared for all the materials, and Vickers microhardness was determined using a digital hardness tester. Data were analyzed using one-way analysis of variance and Tukey-Kramer multiple
comparison tests at a significance level of p < 0.05. RESULTS: Biodentine (42.02; 39.35 MPa) and ProRoot MTA (21.86;
34.13 MPa) showed significantly higher bond strengths than BioAggregate (6.63; 10.09 MPa) in coronal and apical root
dentin, respectively (p < 0.05). Biodentine also differed significantly from ProRoot MTA in coronal dentin. Bond failure
was predominantly adhesive in Biodentine and ProRoot MTA, while BioAggregate showed predominantly mixed failure.
ProRoot MTA (158.52 HV) showed significantly higher microhardness and BioAggregate (68.79 HV) showed the lowest
hardness. CONCLUSION: Biodentine and ProRoot MTA showed higher bond strength and microhardness compared to
BioAggregate.

OBJECTIVES: To evaluate differences in students' performance in a dental morphology course after the
introduction of a 3D software-teaching program. Methods: This retrospective study took place at the College of
Dentistry, University of Dammam, Dammam, Kingdom of Saudi Arabia, from August 2013 to January 2016. The
study included 3 groups of students taking the course during 3 different academic years: group 1, 2013-14 control;
group 2, 2014-2015; and group 3, 2015-2016. The total sample size was 294 (n = 294; group 1 = 94; group 2 = 100;
and group 3 = 100). Group 1 =students did not receive teaching facilitated by a software program, but groups 2 and
3 students were provided with the program's CDs. The final examination grades of the students were statistically
analyzed, retrospectively. Results: The results demonstrated that the students who received software-facilitated teaching (groups 2 and 3) performed better than the students who did not receive it (group 1). Within the same
year for groups 2 and 3, the number of students achieving good grades (greater than 80%) was significantly higher
than the students who achieved average grades (less than 79%), with p-values of 0.012 for group 2 and 0.009 for
group 3. Conclusion: There is a positive correlation between the use of a teaching software program for students
and their performance in final examinations. The addition of computer-based learning, as one of the teaching
methods, could demonstrably boost students' learning.

Indexing Status: Scopus: Web of Science: PubMed:
Abstract
BACKGROUND: Postoperative pain is a potential adverse side effect of oral surgeries, and attempts should be
made to prevent or minimize it. This study compares efficacy of preemptive ibuprofen and dexamethasone
protocols for pain prevention or control after surgical implant placement. METHODS: This prospective, double-
masked, parallel-group, placebo-controlled, randomized clinical trial included 117 patients with planned dental
implant placement. Patients were assigned to receive one of three different protocols: 1) 600 mg ibuprofen 1 hour
before surgery and another 600 mg 6 hours after the first dose; 2) 4 mg dexamethasone 1 hour before surgery and another 4 mg 6 hours after the first dose; or 3) placebo. Rescue medication (1,000 mg acetaminophen) was made
available to each patient, and they were instructed to take it as necessary. Pain intensity was evaluated via a 101-
point numeric rating scale and a visual analog scale, and discomfort was evaluated using a four-point verbal rating
scale hourly for the first 8 hours after surgery and three times daily for the following 3 days. RESULTS: Ibuprofen
and dexamethasone significantly reduced pain (Kruskal-Wallis; P <0.05) up to 3 days after surgery and discomfort
(P <0.05) up to 2 days after surgery compared with placebo treatment. Both treatments reduced the number of
painkillers taken and increased time before the first painkiller was taken (P <0.01). CONCLUSION: Steroidal
dexamethasone is as effective as non-steroidal ibuprofen for preventing or controlling postoperative pain and

and frequency of anterior loop in Saudi population. A retrospective CBCT study. Saudi Dent J. 2017;29(1):29-35.
Indexing Status: Scopus: Web of Science: PubMed:
Abstract
OBJECTIVES: To determine the position of mental foramen (MF) and frequency of anterior loop (AL) using dental
cone beam computed tomography (CBCT). MATERIALS AND METHODS: The study involved the evaluation of 302
CBCT scans (196 males, 106 females). The position of MF was determined with respect to adjacent teeth, nearest
root apex of adjacent teeth and mandibular borders. MF position was also assessed based on gender and age. In
addition, prevalence of anterior loop was evaluated by categorizing the inferior alveolar canal (IAC) patterns into
linear, perpendicular and anterior looping. RESULTS: The study revealed that the most common position of MF
was below the apex of 2nd premolar accounting for a total of 52.8% of scans whereas, only 29.6% observed MF
between 1st and 2nd premolar (p > 0.05). 38.7% of MF were located at a distance of 1-3 mm from the nearest root
apex (2nd premolar), followed by a distance of less than 1 mm in 17.05 of cases. 63.2% of foramen on left side of
the mandible were observed below the apex of 2nd premolar in females (p = 0.023). Statistically significant
findings were observed with regards to position of MF in different age groups (p < 0.05). The most common IAC
pattern observed was linear in nature which accounted for 46.2% of cases followed by perpendicular pattern
(38.6%). AL was found only in 15.2% of cases. CONCLUSIONS: Our sample population most commonly exhibited
MF below the apex of 2nd premolar with linear IAC pattern. AL was regarded as the least common pattern in Saudi
population.

Abstract
Purpose: To investigate the efficacy of Ivoclean as a ceramic cleansing agent, by assessing shear bond strength of
pre-etched lithium disilicate (LD) ceramic to resin cement. Materials and Methods: Seventy LD discs (10 × 10 × 4
mm) were fabricated and etched using 5% hydrofluoric acid (HF) for 20 s. Ten specimens were not exposed to
saliva and silicone disclosing medium (negative control). The other 60 specimens, divided into six groups (n = 10),
were exposed to saliva for 20 s and silicone disclosing medium for 3 min. Following contamination, 10 specimens
were not cleansed (positive control). The remaining five groups were exposed to one of the five different cleansing
agents: 96% isopropanol, 37% phosphoric acid-30 s, 5% HF acid- 20 s, 5% HF acid- 120 s, and Ivoclean paste-20 s.
All specimens were treated with primer and bonded to a self-curing resin cement. Before shear bond strength
testing, all specimens were thermocycled (3000 cycles; 5–55°). Results: Contamination of pre-etched LD ceramic
specimens significantly reduced the shear bond strength values from 22.39 ± 0.38 MPa (negative control) to 6.54 ±
0.90 MPa (positive control) (p < 0.05). Cleansing of contaminated ceramic specimens with 5% HF acid [20 s (19.28
± 1.06 MPa) and 120 s (20.04 ± 1.09 MPa)] and Ivoclean (18.30 ± 0.97) provided significantly higher bond strength
values than other cleansing methods with 37% phosphoric acid and 96% isopropanol (p < 0.05). Conclusion:
Ivoclean and 5% HF acid were found to be effective in cleansing of LD ceramic surface by demonstrating maximum
increase in shear bond strength values as compared to contaminated LD ceramics.

Abstract
The high prevalence of dental caries in children worldwide is a major oral health problem which requires
early intervention. Dental caries is mainly caused by the action of acids produced by bacteria in addition
to many other factors. Recent genetic studies have reported that a number of genes are associated with
the susceptibility to dental caries. The majority of these genes are associated with inflammation,
increased susceptibility to infection, and dentine matrix formation. Using the TaqMan assay and direct
DNA sequencing, the prevalence of 6 single-nucleotide polymorphisms (SNPs) in MMP9, MBL2, MMP2,
and TIMP2 genes was determined in 102 children with caries and in 100 age-matched caries-free
controls. Out of the 6 SNPs tested in the 4 selected genes, only rs11003125 in the MBL2 gene was shown
to be associated with a high prevalence of caries in our cohort. In addition, haplotype analysis of the 6
SNPs tested revealed that certain haplotypes, namely GT of rs11003125G and rs7501477T and GT of
rs7096206G and rs7501477T, were found to be associated with a high prevalence of dental caries in our
cohort, while haplotype AG of rs17576A and rs7501477G was found to have a protective effect
against dental caries. In conclusion, the data indicate that rs11003125 in the MBL2 gene was shown to be
associated with a high prevalence of caries in our cohort, and 2 haplotypes are also involved in the
increased susceptibility to dental caries.

Abstract
Objective: To investigate an association between the awareness about the effects of tobacco consumption on oral
health and the likelihood of smoking among male schoolchildren. Materials and Methods: A cross sectional study
was conducted using a multistage random sampling technique. The participants (ages 15–19 years) were recruited
from male public high schools in Greater Dammam in Saudi Arabia. A pretested questionnaire inquired
participants' awareness about the effects of smoking on oral health. SPSS (Released 2013, IBM SPSS Statistics for
Windows, Version 22.0. Armonk, NY: IBM Corp) was used to calculate unadjusted and adjusted odds ratio (OR) and
95% confidence interval (CI). Multiple logistic regression and interaction analyses were performed to identify the
factors associated with the probability of smoking behavior among children. Results: More than 69.9% (n = 277) of
participants were aware of the adverse effects of tobacco consumption on oral health which included poor oral
health, bad taste and breath, periodontal disease, dental caries, oral ulcers, and oral cancers. The odds of smoking
were 22%–47% lower among schoolchildren who were aware of the consequences of smoking on oral health than
those who were unaware of these complications. The students who believed that smoking can cause oral ulcers and
negatively affects oral health had a lower probability of smoking (OR: 0.414; CI: 0.201–0.50) and (OR: 0.433; CI:
0.194–0.965), respectively in comparison with those who thought that smoking had no such negative impacts.
Conclusions: Schoolchildren with increased awareness of smoking effects on oral health were less likely to smoke.
Educating students about the complications of smoking on oral health should be the part of smoking cessation
programs and policies.

Abstract
In the current investigation, the potential alleviating effects of tianeptine against bone loss induced in
ovariectomized (OVX) rats was determined. Two weeks following a bilateral ovariectomy operation, tianeptine
treatment (12.5 and 25mg/kg/twice/d) was initiated and continued for twenty-eight consecutive days. Changes in
serum and urinary bone turnover biomarkers and osteoclastogenesis-inducing factors were estimated. The femoral
bone mineral content was estimated using inductively-coupled-plasma mass spectrometry. Morphometric
alterations of distal femoral bones were observed in the cortical and trabecular structures using micro-CT. Finally,
femur bones were assessed for histopathological changes. The lack of estrogen significantly increased the levels of
bone turnover biomarkers and inflammatory mediators. Mineral concentrations in the femoral bones were
reduced in the OVX group. Furthermore, the femoral bone micro-architecture determined using micro-CT and
histopathology were significantly altered by estrogen deficiency. Tianeptine, particularly the higher dose, corrected
the elevated levels of bone metabolic products and pro-inflammatory cytokines. Tianeptine also improved mineral
concentrations in femoral bones and the disturbed morphometric and histopathological features in OVX rats. In
conclusion, tianeptine alleviated the osteoporotic changes in OVX animals, which may be via inhibition of the
hypothalamic-pituitary-adrenal axis stress and osteoclastogenesis-provoking factors, suggesting attenuation of
bone matrix degradation and osteoclast stimulation.
