Abstract

Background and aims: Monitoring oral diseases is needed to allocate resources, planhealth services and train dental workforce. Caries is one of the oral diseases most commonlyincluded in oral health surveillance systems. The present study assessed (1) caries data availabilityin the administrative regions of Saudi Arabia and (2) factors associated with this availability. Methods: We collected caries data in the period 2008–2018 in Saudi Arabia (outcome variable).The explanatory variables included region-level factors: (a) socio-economic indicators (percentageof individuals with university education, percentage of category A governorates, percentage ofowned houses, households with computers, internet and smart phones) and, (b) oral health researchpotential indicators (number of Dental Public Health (DPH) specialists, Ministry of Health (MoH)dentist to population ratio and number of dental schools). ArcGIS was used for data visualizationand logistic regression was used for analysis. Results: Twenty-two studies provided caries data for 46.2% of the regions which were inhabitedby 84.7% of the population. Region-level data availability was associated with the number of dental schools (OR = 1.63) with 61.5% of the regions correctly classified. More regions were correctly classified when population to MoH dentist ratio (76.9%) and the number of DPH specialists (92.3%) were included. Conclusions: Caries data were available for half of the administrative regions in Saudi Arabia and data availability was associated with higher number of dental schools. The presence of DPH specialist provided the critical mass to collect caries data. 2. Al-Ansari A, El Tantawi M, Mehaina M, Alhareky M, Sadaf S, AlHumaid J, AlAgl A, Al-Harbi F.

Comput Dent. 2019; 22(1):45-53.


Abstract AIM: To evaluate the marginal adaptation and internal fit of milled fiber post and cores using different scanning methods. MATERIALS AND METHODS: Thirty typodont tooth models (Nissin) with pulp cavity were endodontically treated and prepared to receive 30 fabricated fiber post and cores. Three different methods of scanning were used (n = 10): an intraoral scanner (IOS) (Trios 3; 3Shape) to directly digitalize the post space (Group T) and a laboratory scanner to indirectly digitalize the resin pattern (Group RP) and the silicone impression (Group S) of the post space. All the specimens were examined using an optical microscope for the measurement of the vertical marginal discrepancy (VMD), and five in each group were scanned using microcomputed tomography (µCT) for the assessment of the VMD, the internal fit at the corner (IFC), post apex (PA), and at four horizontal cross-sections (CS1-4) inside the canal. All data were analyzed using mixed-design ANOVA, followed by pairwise testing to identify the differences (α = 0.05). RESULTS: Statistical analysis revealed that Group T was associated with the smallest cement space compared with Group RP (P = 0.001) and Group S (P < 0.001) for VMD using µCT or direct microscopy (OM) (P < 0.001). Similarly, the cement space for Group T was smaller than that of Group S (P = 0.039) when measured at the IFC (µCT), and smaller than Group RP (P = 0.025) when measured at CS1-4 (µCT), with CS1 larger than CS3 (P = 0.015). There was no significant difference at PA (P = 0.271). CONCLUSION: Better adaptation was achieved with a complete digital workflow. Scanning the resin pattern or the silicone impression introduced more variables in the digital process or milling of a one-piece fiber post and core. 4.

Indexing Status: Scopus: Web of Science: PubMed: Abstract Tissue engineering and regenerative medicine are emerging as future approaches for the treatment of acute

and chronic diseases. Numerous clinical conditions exist today and include congenital disorders, trauma,

infection, inflammation, and cancer, in which hard and soft tissue damage, organ failure and loss are still not

treated effectively. Researchers are constantly developing new biomaterials and tissue-engineered

technologies to stimulate tissue regeneration. Various emerging approaches according to organ, tissue, disease

and disorder are identified. Irrespective, engineered biomaterials are required to regenerate and ultimately

reproduce the original physiological, biological, chemical, and mechanical properties. Biodegradable materials

have been used extensively as regenerative therapies. The selection, design, biological and physicochemical

properties of these materials are important and must be considered for stimulating tissue growth. In this

review, we critique recently developed biodegradable materials for tissue regeneration of some targeted

organs e.g., skin, nerves, blood vessels, heart, cornea, trachea, dental/oral structure and bones.

Abstract Background: Denture with antimicrobial activities is desirable to prevent Candida albican adhesion subsequently decreasing the susceptibility of denture stomatitis incidence. Azadirachta Indica, commonly known as Neem powder has antimicrobial effect but the effect of its addition to acrylic denture base on C.

albicansadhesion has not been investigated. The aim of this study was determine whether adding neem powder

to acrylic denture base materials could reduce Candida albicansadhesion. Material and Methods: One hundred

and twenty acrylic resin denture specimens were fabricated and divided into heat-polymerized (n=60) and

auto-polymerized (n=60) groups. Each group was further divided into 6 groups (n=10) based on the neem

concentration: 0, 0.5, 1, 1.5, 2 and 2.5 wt% of the polymer. After polymerization, the specimens were polished,

stored in distilled water, sonicated, sterilized, submerged in artificial saliva containing C. albicans, and finally,

placed in an incubator at 37°C. Slide counting and direct culture methods were used to assess the antifungal

effects of the neem addition. An analysis of variance and post hoc Tukey’s test were performed for the data

analysis (p≤0.05 was statistically significant). Results: Based on the results, the neem addition significantly

decreased the C. albicans count when compared to the control group (p≤0.05). Moreover, the count decreased

as the neem concentration increased (lowest count with 2.5 wt%). Conclusions: The results suggest that adding

neem powder to acrylic resin denture base materials reduces the adhesion of C. albicans; therefore, the

incorporation of neem could be a possible denture stomatitis prevention method.

Association with Carious Lesions in Other Permanent Teeth. J Clin Diagn Res. 2019;13(1).


Abstract

Introduction: Dental caries is most prevalent in first permanent molars and it is bilaterally distributed in

permanent maxillary and mandibular molars. It is assumed that dental caries in first permanent molar is

related to caries in other permanent teeth possibly due to its infectious and transmissible nature. However,

there is limited data about a relationship between caries in first permanent molar and other permanent teeth.

Aim: To assess the association between dental caries in first permanent molar and other permanent teeth in

school children. Materials and Methods: This cross-sectional study was conducted on male intermediate

school children (12-15 years) in Dammam, Saudi Arabia in 2016. A sample of 1250 children was randomly

selected. Data collection involved clinical examination of caries using the World Health Organisation (WHO)

criteria and a pilot-tested questionnaire. Training and calibration of examiners were conducted (k =0.6).

Statistical analyses involved descriptive statistics, univariate and multivariate logistic and linear regressions

using SPSS software. Results: Of 1250 children invited, 1109 participated with a response rate of 88.7%. The

first permanent molars had the highest percentage of dental caries among all permanent teeth (50.4%) with a

mean of 1.08 carious molars. This was followed by second permanent molars (prevalence=14.7%, mean

number of decayed molars=0.25). The canines had the lowest prevalence of dental caries (1.8%) and the mean

number of carious canines was 0.02. Logistic regression showed that caries in first permanent molars were

significantly associated with higher odds of caries in incisors (OR=4.87), second molars (OR=4.26) and

premolars (OR=3.57). It was found that a unit increase in the number of carious first molars was associated

with a significant increase in the number of carious incisors, premolars and second molars. Conclusion: The

study found associations between caries in first permanent molar with caries in other permanent teeth.

School-based oral health promotion programs should start early to target young school children when first

permanent molars start to erupt.

Abstract Development of a guided occlusive biodegradable membrane with controlled morphology in order to restrict the ingrowth of epithelial cells is still a challenge in dental tissue engineering. A bilayer membrane with a non-porous upper layer (polyurethane) and porous lower layer (polycaprolactone and bioactive glass composite) with thermoelastic properties to sustain surgery treatment was developed by lyophilization. Morphology, porosity, and layers attachment were controlled by using the multi-solvent system. In vitro and in vivo biocompatibility, cell attachment, and cell proliferation were analyzed by immunohistochemistry and histology. The cell proliferation rate and cell attachment results showed good biocompatibility of both surfaces, though cell metabolic activity was better on the polycaprolactone-bioactive glass surface. Furthermore, the cells were viable, adhered, and proliferated well on the lower porous bioactive surface, while non-porous polyurethane surface demonstrated low cell attachment, which was deliberately designed and a pre-requisite for guided tissueregeneration/guided bone regeneration membranes. In addition, in vivo studies performed in a rat model for six weeks revealed good compatibility of membranes. Histological analysis (staining with hematoxylin and eosin) indicated no signs of inflammation or accumulation of host immune cells. These results suggested that the fabricated biocompatible bilayer membrane has the potential for use in periodontaltissue regeneration 8. Jaber L, Fatani H, Aldhahri SF. Absence of human papillomavirus in oral cavity squamous cell carcinomas

among Saudi patients. Clin Exp Dent Res. 2019; 5:38–43.


Abstract

This study aimed to examine the possible association of human papillomavirus (HPV) with oral cavity squamous cell carcinomas (OCSCCs) in Saudi Arabia. Forty-five paraffin-embedded tumor blocks that represent different subsets of OCSCCs between 2010 and 2014 were retrieved and histologically evaluated. The presence of high-risk HPV (16, 18, 31, and 33) was assessed by p16-immunohistochemistry followed by DNA detection using in situ hybridization technique. Twenty-four patients were male with the mean age of 59.3 years, and 21 patients were female with the mean age of 61.2 years. Forty-one cases were positive for p16 immunostaining, and the remaining four cases were negative. However, none of the 45 cases showed DNA-expression for any HPV subtypes (16, 18, 31, and 33). High-risk HPV appears not to be involved in the etiology of OCSCCs in older Saudi patients, but further studies with cross section of a younger age group are still required. 9.

Objectives: Light-cured resin-based composites (RBCs) are the preferred option to restore teeth. Dental light-

curing units (LCUs) should deliver adequate light energy to ensure good mechanical properties, dimensional

stability, and biocompatibility of the RBC. The aim of this study was to determine the types of LCUs and their

intensity output in private dental clinics. Methods: A form was developed to record information related to the

type of curing lights and their intensity output. A total of 400 curing devices were evaluated using a digital

radiometer in 58 private dental clinics. For each device, three separate 10-s readings were taken and the

average was calculated. For quartz tungsten halogen (QTH) units, a light intensity below 300 mW/cm2 was

considered unsatisfactory, whereas for light-emitting diode (LED) units, a reading below 600 mW/cm2 was

considered unsatisfactory. Results: Out of 400 curing lights, 354 were LEDs and 46 were QTH units. A total of

13% of the lights were considered unsatisfactory. Of the LED units, 12.4% had a light intensity of less than

600 mW/cm2, whereas QTH had 17.3% units with an intensity of less than 300 mW/cm2. Conclusion: The

frequency of LCUs showed a trend towards LED units in private dental clinics, whereas the mean intensity

value from the LED was higher than that from QTH units. Overall, the radiometer is a good tool to assess the

intensity output of LCUs.

Kingdom of Saudi Arabia. J Family Community Med. 2019, 26(1):45.


Abstract

OBJECTIVE: The purpose of this study was to investigate students' perception of the educational climate in a medical school in Dammam, Kingdom of Saudi Arabia (KSA). The difference in the perception of preclinical year students and clinical year students was also evaluated. MATERIALS AND METHODS: This cross-sectional study was conducted among 2nd to 6th year students at the medical college of ImamAbdulrahman Bin Faisal University. "Dundee Ready Educational Environment Measure" (DREEM) was used to evaluate the educationalenvironment. RESULTS: Out of 518, 238 students participated in the study; participation rate of 45.9%. The average DREEM score was 112.38 with a SD of 22.4. Students' perception of atmosphere got the highest score (27.1 ± 6.7) of the five DREEM subscales. The 3rd year had the highest DREEM score compared to students of other levels, while the DREEM score of preclinical students was significantly higher than that of the clinical year students. CONCLUSION: Perception of medical students about the educational climate was more positive than negative. Although the DREEM score and its subdomains showed a positive educational environment, students still mentioned some problematic areas that need to be addressed. Findings of this study could encourage other medical colleges in the KSA to focus on weak areas and address the issues raised by students, especially clinical year students.

Nanodiamond Addition on Flexural Strength, Impact Strength, and Surface Roughness of PMMA Denture Base.

J Prosthodont. 2019, 28(1): e417-25.

Indexing Status: Scopus: Web of Science: PubMed: Abstract Purpose: To assess the effect of addition of different concentrations of nanodiamonds (NDs) on flexural

strength, impact strength, and surface roughness of heat‐polymerized acrylic resin. Materials and Methods:

120 specimens were fabricated from heat‐polymerized acrylic resin. They were divided into a control group of

pure polymethylmethacrylate (PMMA; Major.Base.20) and three tested groups (PMMA‐ND) with 0.5%wt,

1%wt, and 1.5%wt of added ND to PMMA. Flexural strength was determined using the three‐point bending test.

Impact strength was recorded by using a Charpy type impact test. Surface roughness test was performed using

a Contour GT machine. One‐way ANOVA and Tukey's post‐hoc analysis (p ≤ 0.05) were used for statistical

analysis. Results: Acrylic resin reinforced with 0.5% ND displayed significantly higher flexural strength than

the unreinforced heat‐polymerized specimens, acrylic resin reinforced with 1% ND and the 1.5% ND (p <

0.0001). The impact strength of unreinforced heat‐polymerized specimens was significantly higher than all

nano‐composite materials (p < 0.0001) with no significant difference between 1% ND and the 1.5% ND (p >

0.05). The addition of 0.5% ND and 1% ND significantly decreased the surface roughness in

comparison to both control and the 1.5% ND groups (p < 0.0001) while no significant differences between 0.5% ND and 1% ND (p > 0.05) were reported. Nano-composite material (0.5% ND) showed significantly lower surface roughness when compared to other specimens. Conclusions: The addition of NDs to acrylic denture base improved the flexural strength and surface roughness at low concentrations (0.5%), while the impact strength was decreased with ND addition.

Abstract The aims of this study were to assess the perceived levels and sources of stress for Libyan dental students living in a war zone and to compare the results of those students with students living in conflict-free areas in the same country. Eight hundred randomly selected students from three Libyan dental schools in conflict-active and conflict-free regions were invited to participate in a survey in 2016. The survey instrument was the validated Dental Environment Stress (DES) questionnaire translated into Arabic. Responses to the 41 items were on a five-point scale from 0=not stressful at all to 4=very stressful. The response rate was 84.4% (675/800). The results showed that the respondents' overall mean score of stress perception was 2.5 (SD 0.6). There was a statistically significant difference in overall perceived stress between the two groups (p

226(5):354-357.


Abstract

Introduction: Dental plaque is a major aetiological factor in the development of periodontal disease; thus, it is

essential to remove dental plaque to maintain good oral health. We used a simple method to visually evaluate a

patient's dexterity to assess their oral care efficiency. The aim of this study was to evaluate dexterity and the

effect it has on plaque control. Materials and methods: A total of 80 patients, aged between 18 and 60 years,

participated in this study. Participants were asked to pick up peas using chopsticks, and transfer them from one

box (box A) to an empty box (box B), within one minute. The numbers of peas in box B were then counted. The

plaque index score was recorded before and after standardised oral hygiene instructions (OHI) were given to

each participant. Age, sex, dominant hand, and the result of the dexterity test were compared.

Results: Dexterity was the only significant predictor of improvement in oral hygiene after the OHI. All other

variables were included in the model but none were reliable predictors. Conclusion: Dexterity might be a good

predictor of improvement in oral hygiene. We conclude that dexterity should be assessed in order to provide

tailored instructions to each individual.

formation by salts solutions intended for mouthrinses. Restor Dent Endod. 2019, 44(1):e4.


Absrtact

OBJECTIVES: Biofilm formation is critical to dental caries initiation and development. The aim of this study was

to investigate the effects of nicotine exposure

on Streptococcus mutans (S. mutans) biofilm formation concomitantly with the inhibitory effects of sodium

chloride (NaCl), potassium chloride (KCl) and potassium iodide (KI) salts. This study examined bacterial growth

with varying concentrations of NaCl, KCl, and KI salts and nicotine levels consistent with primary levels of

nicotine exposure. MATERIALS AND METHODS: A preliminary screening experiment was performed to

investigate the appropriate concentrations of NaCl, KCl, and KI to use with nicotine. With the data,

a S. mutans biofilm growth assay was conducted using nicotine (0-32 mg/mL) in Tryptic Soy broth

supplemented with 1% sucrose with and without 0.45 M of NaCl, 0.23 M of KCl, and 0.113 M of KI.

The biofilm was stained with crystal violet dye and the absorbance measured to determine biofilm formation.

RESULTS: The presence of 0.45 M of NaCl, 0.23 M of KCl, and 0.113 M of KI significantly inhibited (p <

0.05) nicotine-induced S. mutansbiofilm formation by 52%, 79.7%, and 64.1%, respectively. CONCLUSIONS:

The results provide additional evidence regarding the biofilm-enhancing effects of nicotine and demonstrate

the inhibitory influence of these salts in reducing the nicotine-induced biofilm formation. A short-term

exposure to these salts may inhibit S. mutans biofilm formation.

in rabbits. Br J Oral Maxillofac Surg. 2019, 57(2):157-163.


Abstract Patients with cancer have recently been treated with more advanced targeted chemotherapies that have

greater specificity towards the cancer cells and fewer side effects. However, the periods of treatment take

longer than those of traditional cytotoxic treatments. The aim of this study was to examine the effect

of antiangiogenic targeted chemotherapy on the osseointegration of titanium implants. Fourteen white New

Zealand rabbits were allocated randomly into two groups of seven: the placebo control group and

the Avastin® group. Animals in the Avastin® group had five doses of bevacizumab intraperitoneally

(3 mg/kg/week). The first was given two days before the implant was inserted and the remaining four were

given weekly for four weeks. One titanium implant was inserted in the right distal femoral condyle of each

rabbit. Osseointegration of the implants was measured using microcomputed tomography (CT) and

histomorphometric evaluation. Both of these showed less osseointegration in the Avastin® group than in the

controls. The pharmacological inhibition of angiogenesis by bevacizumab may negatively affect the

osseointegration of titanium implants in rabbits.

Abstract Talon cusp’ is a developmental dental disturbance characterised by a cuspal projection in the cingulum area or

cementoenamel junction, with normal enamel and dentin containing varying degrees of pulp tissue. The

prevalence of talon cusp varies with race, age and the criteria used for diagnosis. It has been reported in the

maxillary and mandibular arches of both the deciduous and permanent dentitions. The prevalence of the talon

cusp in the deciduous dentition is reported to be 2.1% in Saudi Arabian subjects. The purpose of this paper is to

report the rare bilateral presence of talon cusps on the deciduous maxillary central incisors of a 4-year-old

female patient with a family history of consanguineous marriage.

preference to receive oral health information using social media. Acta Odontol Scand. 2019, 77(3):213-218.


Abstract Objectives: To assess (1) adolescents’ preference to use social media (SM) to receive oral health information (OHI) and (2) factors associated with this preference. Materials and methods: A cross-sectional survey was conducted in 2016, Eastern Province, Saudi Arabia including male middle school students. A questionnaire assessed explanatory variables including background, previous OHI seeking practices, internet use purposes, convenience of using SM for OHI and perceived usefulness of obtained OHI. The outcome variable was respondents’ preference to use SM to receive OHI. Simple and multiple logistic regression models were used for statistical analysis. Results: The response rate was 91.2% (456/500). Of those, 57.5% preferred using SM to receive OHI. The odds for this were significantly associated with being Saudi (OR = 3.12, 95%CI = 1.36, 7.18), previously using Twitter (OR = 4.59, 95%CI = 1.77, 11.89) and Instagram for OHI (OR = 2.60, 95%CI = 1.51, 4.45), frequent use of the internet to obtain OHI (OR = 1.25, 95%CI = 1.02, 1.54) and ease of obtaining OHI using the Internet (OR = 2.69, 95%CI = 1.5, 4.39). Conclusion: Most adolescents preferred using SM to receive OHI. This was associated with previous OHI seeking practices and convenience of using SM. These findings have implications for designing SM-based health education campaigns targeting adolescents.

Indexing Status: Scopus: Web of Science: PubMed: Abstract Aim: To assess the prevalence of self-medication for non-oral and oral conditions and associated factors. Study Design: Cross-sectional study. Place and Duration: The outpatient clinics of Alexandria University teaching hospital, Alexandria, Egypt in 2015. Methodology: Visitors responded to a pilot-tested Arabic questionnaire that collected information about medical and dental histories, self-medication and its reasons. The study outcomes were the most frequent non-oral and oral conditions for which antibiotics self-medication was used. Regression analysis was used to assess the association with independent variables and the relationship between the two outcomes. Results: The response rate was 94.3%. The prevalence of antibiotics self-medication for non-oral and oral conditions was 31.6% and 19.4%. The most frequent non-oral and oral conditions where antibiotics self-medication occurred were common cold and toothache (26.3% and 18.2%). Perceiving the condition as non-serious and leftover medications were associated with higher odds of antibiotics self-medication for common cold and toothache (OR= 1.99, 1.99 and 2.84, 1.81). Antibiotics self-medications for the two conditions were strongly associated (OR= 52.00). Conclusions: Self-medications for

17

foral and non-oral conditions are associated and related to modifiable factors including how serious the patients

perceive their condition to be and if they have access to left-over medication.

Abstract OBJECTIVE: Enhancement of CS-GA-PCL-NPs (Glycyrrhizic Acid-encapsulated-chitosan-coated-PCL-Nanoparticles) bioavailability in brain. METHODS: Double emulsification solvent evaporation method in order to develop CS-PCL-NPs (Chitosan-coated-PCL-Nanoparticles) followed by characterization of particle size and distribution, zeta potential, encapsulation efficiency and drug release (in vitro). To determine drug-uptake and its pharmacokinetic profile in brain as well as plasma, UHPLC (triple quadrupole Q-trap) MS/MS method was developed and optimized for CS-GA-PCL-NPs as well as to follow-up examined effective role of optimized NPs in reduction of all brain injury parameters after MCAO through the grip strength, locomotor activity, inflammatory cytokines levels, measurement of infarction volume and histopathological changes in neurons with safety/toxicity after i.n. in animals. RESULTS: The developed NPs showed an average particle size, entrapment efficiency with PDI (polydispersity index) of 201.3 ± 4.6 nm, 77.94 ± 5.01% and 0.253 ± 0.019, respectively. Higher mucoadhesive property for CS-GA-PCL-NPs as compared to conventional and homogenized nanoformulations was observed whereas an elution time of 0.37 min and m/z of 821.49/113.41 for GA along with an elution time of 1.94 min and m/z of 363.45/121.40 was observed for hydrocortisone i.e. Internal standard (IS). Similarly, %CV i.e. inter and intra assay i.e. 0.49-4.41%, linear dynamic range (10-2000 ng/mL) and % accuracy of 90.00-99.09% was also observed. AUC0-24 with augmented Cmax was noted (**p

Nanoparticles: A Literature Review. Int J Biomater. 2019. Article ID 6190610.

https://doi.org/10.1155/2019/6190610.


Abstract Titanium dioxide nanoparticles (TiO2NP) have gained interest in the dental field because of their multiple uses in addition to their antimicrobial effect. One of the applications in dentistry involves the incorporation into poly methyl methacrylate (PMMA) resin. However, there is a lack of evidence on their effects on the behavior of the resulting nanocomposite. Therefore, the present review aims to screen literatures for data related to PMMA/TiO2 nanocomposite to figure out the properties of TiO2 nanoparticles, methods of addition, interaction with PMMA resin matrix, and finally the addition effects on the properties of introduced nanocomposite and evidence on its clinical performance. Regardless of the latest research progress of PMMA/TiO2 nanocomposite, the questionable properties of final nanocomposite and the lack of long-term clinical evidence addressing their performance restrict their wide clinical use. A conclusive connection between nanoparticle size or addition method and nanocomposite properties could not be established.
