Sugar content in infant formula: Accuracy of labeling and conformity to guidelines.

BACKGROUND: Infant formulae are a primary source of nutrition during the first years of life, to which sugars are frequently added. This may contribute to adverse dental health problems if consumed excessively when coupled with prolonged and nocturnal feeding habits. AIM: To assess the amount and type of dietary sugars in commercially available infant formulae in the UAE. DESIGN: Sucrose, glucose, and fructose were measured in 71 different brands of commercially available infant formulae for retail sale in the UAE. Analysis was performed using high-performance liquid chromatography with refractive index detection. Sugar values were compared with the reported levels on the nutritional labels. A comparison between findings, product labels, and international standards for infant formulae was performed. RESULTS: Of the 71 samples, 23 had detectable sugar levels, varying between sucrose, glucose, and fructose. Ten samples were found to have sugars contributing to more than 5% of total energy intake ranging between 5.68% and 27.06%. All infant formula packages had carbohydrate levels mentioned on the labels, but very few mentioned the added sugar content. CONCLUSIONS: Many infant formula products tested contained sugars that exceeded the standard recommended intake. Tighter regulations that monitor the amount of sugar in infant formulae and guidelines for comprehensive labeling systems are required.

The Effect of Chlorhexidine on Bacterial Contamination of Hall Technique Elastomeric Orthodontic Separators and Gingival Health: A Pilot Study

ABSTRACT Objective: To study the effect of chlorhexidine on elastomeric orthodontic separators (EOS) bacterial-colonisation and gingival-health in Hall technique (HT) patients. Material and Methods: Prospective in-vivo pilot clinical study of EOS bacterial colonisation and primary-molar gingival health assessment in 20 patients (mean age 5.45±1.27 years) requiring bilateral HT crowns (40 teeth). One side received 1-minute 0.12% chlorhexidine-soaked-EOSs (Chx-EOSs), and the other side dry-EOSs (NoChx-EOSs). The EOSs were removed five-days later and underwent a bacterial enumeration technique. Plaque (PI) and Gingival (GI) indices were assessed pre-, five-days and three-months post-treatment. Wilcoxon-Signed-Rank/McNemar-Chi-square statistics were used (p<0.05). Results: Baseline unused/packaged EOSs' sterility check yielded zero colony-forming-units (CFU) per millilitre, but 100% of the used EOSs became colonised by oral-microorganisms. An overall trend of lower mean CFU count in Chx-EOSs (3.415± 0.78 x105 CFU/ml) compared to NoChx-EOSs (6.157±1.48 x105 CFU/ml) was observed (p=0.009). Both NoChx-EOSs and Chx-EOSs insertion sites showed evidence of gingivitis with no difference between PI and GI indices by site over time. Conclusion: There was a lower trend of bacterial colonization in chlorhexidine treated EOSs and an occurrence of gingivitis pre/post HT-treatment regardless of EOS type. The lack of difference in the gingival health may be inconclusive due to this pilot's low power suggesting the need for robust large scale studies.

Characteristics of Pediatric Dental Treatment Provided under General Anesthesia in Dubai, United Arab Emirates: A Retrospective Analysis.

Background: Dental general anesthesia (DGA) is a widely utilized technique in pediatric dentistry and is indicated for a variety of cases such as very young children and children with special healthcare needs (SHCN). In the United Arab Emirates (UAE), there is a paucity of studies relating to this subject. Objective: To analyze the characteristics of DGA treatment in special healthcare needs and healthy children in the only postgraduate dental hospital in Dubai, UAE. Materials and Methods: A retrospective analysis was conducted on the electronic records of all Dubai Dental Hospital (DDH) pediatric patients who underwent DGA in the period between January 1st, 2016, and 29th of February 2020. Results: The study population consisted of 98 children. A total of 26 children had a medical condition and were categorized as SHCN. The most common justification for DGA was dental caries and a lack of cooperation due to young age. SHCN patients received significantly more preventive measures and significantly fewer pulp therapies than healthy patients. Conclusion: We found that the services provided under DGA for healthy pediatric patients differ from those provided to SHCN patients. Frequently missing recall appointments following DGA increased the likelihood of the need for further restorative dental treatment. These results highlight the importance of robust prevention and follow-up programs for children treated under GA.

What is the effect of preterm birth on permanent tooth crown dimensions? A systematic review and meta-analysis.

BACKGROUND: The permanent tooth formation process may be disrupted in preterm infants with potential discrepancies in size and subsequent occlusal disturbances. OBJECTIVE: To systematically analyse and quantitively synthesize the available evidence regarding the impact of preterm birth on permanent tooth crown dimensions. SEARCH METHODS: Unrestricted searches in 6 databases and manual searching of the reference lists in relevant studies were performed up to March 2021 (Medline via PubMed, CENTRAL, Cochrane Database of Systematic Reviews, Scopus, Web of Science, ProQuest Dissertations and Theses Global). SELECTION CRITERIA: Observational studies investigating permanent tooth crown dimensions in preterm and control full-term born individuals. DATA COLLECTION AND ANALYSIS: Following study retrieval and selection, relevant data were extracted, and the Newcastle-Ottawa scale was used to assess the selection, comparability, and outcome domains. Exploratory synthesis and meta-regression were carried out using the random effects model. RESULTS: Three studies were located from the initially retrieved records and the assessments with the Newcastle-Ottawa scale identified issues regarding the selection and comparability domains. Overall, the mesiodistal and the buccolingual dimensions of the permanent teeth in both dental arches tended to be smaller in children born prematurely than full term children. Subgroup analyses showed statistically significant differences for the extremely preterm to control group comparisons for the incisors and the first molars. Meta-regression showed a modificatory effect of gestational age and racial background but not of birth weight and gender on tooth size. The quality of available evidence was rated at best as moderate. CONCLUSIONS: Premature birth could potentially be associated with reduced tooth-crown dimensions in some permanent teeth especially in children born extremely preterm. Although the results from these observational studies should be approached with caution until more information becomes available, the possible clinical implications in terms of diagnosis and treatment planning should be considered.

How Do Schoolchildren View Other Children Who Have Discolored Teeth?

OBJECTIVES: Facial look and expression affect how people are viewed by others. This study aimed to evaluate how schoolchildren in the Emirate of Sharjah, United Arab Emirates view their peers who have discolored teeth. MATERIALS AND METHODS: A cross-sectional study using randomized cluster sampling of Sharjah public schools was conducted. A previously developed and validated social attribute questionnaire was utilized to determine children's dental appearance-related judgments. Children aged 11-14 years were given photographs of subjects either with discolored teeth or without, and they were asked to rate them using six positive and five negative signifiers. The total attribute score (TAS) ranged from 11 (most negative) to 44 (most positive). A linear regression analysis and t-tests were performed to determine the effects of gender and age in mean TAS. RESULTS: TAS was significantly lower among discolored teeth photographs when compared with photographs without teeth discoloration (P = 0.004). TAS was found to be significantly higher with increased age (P = 0.035), but gender had no significant effect. CONCLUSION: Teeth discoloration resulted in more negative social judgment between Sharjah schoolchildren and their peers.

Changes in preschool children's oral health-related quality of life following restorative dental general anaesthesia.

Background Early childhood caries is the most common childhood disease in preschool children which often requires dental treatment under restorative dental general anaesthesia (RDGA).Aim To assess the effect of RDGA on preschool children and their families' oral health-related quality of life (OHRQoL).Methods A cross-sectional study using a RDGA pre- and post-operative survey to evaluate changes in OHRQoL. Parents completed the Early Childhood Oral Health Impact Scale (ECOHIS) survey before and after their children underwent specialist paediatric RDGA in the United Arab Emirates from 1 March 2017 to 28 February 2018. The ECOHIS and its effect size (ES) served to evaluate children's OHRQoL status and changes, and the Wilcoxon signed-rank and the Kruskal-Wallis tests were used for statistical analyses.Results The mean number of decayed, missing and filled teeth (DMFT) of the children (N = 173, mean age 4.6 years) before the treatment was very high (13.8 ± 3.07). Children's pain and eating problems, and parents feeling upset and guilty, were the most frequently reported impacts at baseline. The ECOHIS scores decreased significantly (p <0.001) after RDGA, revealing a large ES for the child (2.19) and family (2.79) sections of the ECOHIS.Conclusions Preschool children's RDGA resulted in significant improvement in all child and family physical, psychological and social aspects of OHRQoL.

Assessment of Paediatricians' Oral Health Knowledge, Behaviour, and Attitude in the United Arab Emirates.

AIM: Paediatricians' oral health knowledge is essential for early detection of disease, appropriate advice, and proper referral. Therefore, this study aimed to evaluate the knowledge, behaviour, and attitude of paediatricians practicing in the United Arab Emirates (UAE) regarding children's oral health. Study Design. Cross-sectional survey. METHODS: A questionnaire consisting of 16 questions was completed after piloting by a sample of randomly selected registered UAE paediatricians. Scores of knowledge (out of 9), behaviour (out of 4), and attitude (out of 3) were calculated. Statistical analysis was performed using Shapiro-Wilk, Mann-Whitney U, and Kruskal-Wallis tests. Statistical significance was set as P < 0.05. RESULTS: A total of 185 surveys were completed. Nearly half of the paediatricians (95 (51.4%)) identified the appropriate age for child's first dental visit; while 88 (47.6%) believed that the appropriate age to start brushing was after the eruption of the primary molars (2-3 yrs), and 132 (71.4%) believed that the ideal time to give sugary snacks is in between meals. 123 (66.5%) participants said that they would prescribe antibiotics to treat local dental sepsis without fever. Experienced paediatricians and those trained in Western countries had significantly better knowledge about oral health (P values 0.040 and 0.031 consecutively). The scores of attitude, behaviour, and knowledge were correlated, and a positive relationship between the scores of knowledge and behaviour was found (r = 0.241, P=0.001) and between scores of attitude and behaviour (r = 0.197, P=0.007). CONCLUSIONS: The results demonstrated a general lack of knowledge of oral health aspects by UAE paediatricians. Furthermore, continuous education in the subject is recommended.

Knowledge of dental faculty in gulf cooperation council states of multiple-choice questions' item writing flaws.

Multiple-Choice Questions provide an objective cost/time effective assessment. Deviation from appropriate question writing structural guidelines will most probably result in commonly ignored multiple-choice questions writing flaws, influencing the ability of the assessment to measure students' cognitive levels thereby seriously affecting students' academic performance outcome measures. To gauge the knowledge of multiple-choice question items writing flaws in dental faculty working at colleges in Gulf Cooperation Council (GCC) countries. A cross-sectional short online Survey MonkeyTM multiple-choice questions-based questionnaire was disseminated to dental faculty working in GCC countries during the academic year 2018/2019. The questionnaire included five test incorrect (flawed) multiple-choice questions and one correct control question. The participants were asked to identify flawed multiple-choice question items from the known 14 items writing flaws. Out of a total of 460 faculty, 216 respondents completed the questionnaires, 132 (61.1%) were from Saudi Arabia, while numbers of participants from United Arab Emirates, Kuwait and Oman were 59 (27.3), 14 (6.5%) and 11 (5.1%) respectively. Majority of participants were male (n = 141, 65.9%) compared to 73 females (34.1%). Eighty percent of the participants possessed more than five years of teaching experience. Assistant professors constituted the majority (43.3%) of the academic positions participating in this study. The overall fail rate ranged from 76.3% to 98.1% and almost 2/3rds of the participants were unable to identify one or more of the flawed item(s). No significant association was observed between the demographics (age, region, academic position and specialty) and knowledge except that of participant's gender (p < 0.009). GCC dental faculty demonstrated below average knowledge of multiple-choice question items writing flaws. Training and workshops are needed to ensure substantial exposure to proper multiple-choice question items construction standards.

A single-centre investigator-blinded randomised parallel-group study protocol to investigate the influence of an acclimatisation appointment on children's behaviour during N2O/O2 sedation as measured by psychological, behavioural and real-time physiological parameters.

AIMS AND OBJECTIVES: To describe a study protocol of a randomised control trial (RCT) assessing the effectiveness, in reducing dental anxiety, of an acclimatising nitrous oxide sedation (N2O) session prior to actual dental treatment with N2O. MATERIALS AND METHODS: A single-centre investigator-blinded parallel-group RCT conducted in a postgraduate dental hospital in Dubai, United Arab Emirates (UAE). Anxious children requiring N2O (aged 5-15 years) will be randomly assigned to; a study group: children who will have a preparatory N2O trial experience or; a control group: children who will only have N2O explained to them. Treatment with N2O for both groups will start at the second visit. The following outcomes will be recorded: completion of dental treatment, anxiety scores at baseline and after treatment (using the Modified Child Dental Anxiety Scale faces), behaviour of the child (using Frankl Rating Behaviour Scale) and the acquisition of real-time physiological anxiety-related parameters (using E4® electronic wrist devices). RESULTS: The data will be analysed statistically. DISCUSSION: There is a paucity of research regarding dental N2O acclimatising appointments. This RCT will supplement existing literature. CONCLUSIONS: This RCT will report whether prior acclimatising of a child to N2O sedation is effective, or not, in improving dental treatment behaviour.

Use of the Hall technique by specialist paediatric dentists: a global perspective.

Background The Hall technique (HT) is popular with UK paediatric dentists (PDs). Global PDs perception/use of HT is unknown.Aim To investigate global PDs opinions/use of HT.Materials and methods A cross-sectional questionnaire of 26 questions was sent to specialist PDs across the globe.Results Responses of 709 PDs from six continents were obtained. The majority (n = 654, 92.32%) had heard about HT but only 50.6% (n = 358) used it, with wide country variations. Respectively, 37.5%, 31.5% and 31% were neutral, against or supportive of HT when they initially heard about it. Only 17% of HT users said it was always the treatment of choice for non-pulpal asymptomatic carious primary molars (NPACPMs), 62% would take a pre-operative radiograph, 65% would consider using high speed drills before HT, 63% would never consider HT under general anaesthesia, 56% would use HT under N2O sedation. Finally, in a clinical scenario of a NPACPM in a cooperative 6-year-old, 75% of PDs would choose conventional restorative methods over the HT.Conclusion The HT is recognised, but not used, by an outright majority of PDs across the globe. Identifiable barriers such as lack of training, perception as substandard dentistry and perceived lack of evidence reduced its use.

Hall technique crowns and children's masseter muscle activity: A surface electromyography pilot study.

BACKGROUND: Hall technique crowns (HTCs) alter the occlusion temporarily, potentially affecting jaw muscles, particularly the masseter - the primary jaw-closing muscle. AIM: To assess masseter muscle activity (MMA) in children treated with a unilateral HTC. DESIGN: In 12 children treated with a single HTC, bilateral MMA was recorded with surface electromyography (sEMG) for ten cycles of Rest Position (RP) and Maximum Voluntary Clenching (MVC) over 20 seconds immediately pre-HTC cementation (Pbase ), immediately post-HTC cementation (Pimmed ), at 2 weeks post-HTC cementation (P2w ) and at 6 weeks post-HTC cementation (P6w ). t test, ANOVA and post hoc statistics were used (P < .05). RESULTS: As expected, MMA was low at rest and increased during maximal jaw clenching (P < .0001). MMA (mean ± SD) increased significantly (P < .001) between RP and MVC at: Pbase [from 1.60 µV·s (±0.96) to 5.40(±2.30)]; Pimmed [1.57(±1.15) to 3.75(±1.87)]; P2w [1.39(±0.54) to 5.54(±1.45)] and finally P6w [1.46(±0.56) to 6.45(±2.56)]. Rest MMA at Pbase , Pimmed , P2w and P6w remained unchanged (P = .18) whereas Pbase clench MMA reduced by a third at Pimmed (P < .001), returned to and exceeded baseline levels at P2w (P = .822) and P6w (P < .001), respectively. CONCLUSIONS: This pilot study showed that Hall technique crowns may affect masseter muscle activity in children. Clench MMA was reduced immediately post-treatment but returned to and later exceeded baseline levels at 2 and 6 weeks, respectively. Rest MMA remained unchanged.

Enamel defects and caries prevalence in preterm children aged 5-10 years in Dubai.

Background: Enamel defects (EDs) are commonly reported dental findings in preterm/low birthweight children. EDs potentially increase caries susceptibility.Aim: To assess the prevalence of EDs and dental caries in a group of preterm children (aged 5-10 years) in Dubai, United Arab Emirates (UAE).Methodology: A retrospective cohort study of medical records of 62 preterm children (mean age 8.1 ± 1.54) and 62 full-term children (mean age 8.1 ± 1.73) of both genders born in a UAE children's hospital were studied. These children were dentally assessed for EDs and caries by a calibrated examiner.Results: EDs were 4.34 times more prevalent among preterm children [odd ratio (OR) = 4.338, CI 95% [2.010-9.366]. The prevalence of EDs in the pre-term group was 58.15%, significantly higher (P < 0.01) than the full-term control group (24.2%). Birth weight, intubation and type of delivery were statistically significant factors contributing to EDs. In the primary dentition, the mean dmft was 4.61 ± 4.30, while in the permanent dentition DMFT was 0.38 ± 0.99. There was a statistically significant difference in permanent teeth caries experience amongst pre-term children compared to the full-term control as measured by DMFT (P = 0.008).Conclusion: EDs and dental caries in permanent dentition in the pre-term group were significantly higher than the full-term group.

Evaluating the Quality of Multiple Choice Question in Paediatric Dentistry Postgraduate Examinations.

OBJECTIVES: This study aimed to evaluate the quality of multiple choice question (MCQ) items in two postgraduate paediatric dentistry (PD) examinations by determining item writing flaws (IWFs), difficulty index (DI) and cognitive level. METHODS: This study was conducted at Mohamed Bin Rashid University of Medicine and Health Sciences, Dubai, UAE. Virtual platform-based summative versions of the general paediatric medicine (GPM) and prevention of oral diseases (POD) examinations administered during the second semester of the 2017-2018 academic year were used. Two PD faculty members independently reviewed each question to assess IWFs, DI and cognitive level. RESULTS: A total of 185 single best answer MCQs with 4-5 options were analysed. Most of the questions (81%) required information recall, with the remainder (19%) requiring higher levels of thinking and data explanation. The most common errors among IWFs were the use of "except" or "not" in the lead-in, tricky or unfocussed stems and opportunities for students to use convergence strategies. There were more IWFs in the GPM than the POD examination, but this was not statistically significant (P = 0.105). The MCQs in the GPM and POD examination were considered easy since the mean DIs (89.1% ± 8.9% and 76.5% ± 7.9%, respectively) were more than 70%. CONCLUSION: Training is an essential element of adequate MCQ writing. A general comprehensive review of all programme's MCQs is needed to emphasise the importance of avoiding IWFs. A faculty development programme is recommended to improve question-writing skills in order to align examinations with programme learning outcomes and enhance the ability to measure student competency through questions requiring higher level thinking.

A single-centre investigator-blinded randomised parallel group clinical trial to investigate the effect of probiotic strains Streptococcus salivarius M18 and Lactobacillus acidophilus on gingival health of paediatric patients undergoing treatment with fixed orthodontic appliances: study protocol.

BACKGROUND: There is limited data on the beneficial effects of probiotics on the gingival health of patients undergoing treatment with fixed orthodontic appliances. This study aims to compare the effect of probiotic tablets combined with regular oral hygiene versus regular oral hygiene alone on gingival status in these patients. The effect of probiotic intake on plaque formation and salivary microbiome composition will be also assessed. METHODS AND ANALYSIS: This is a 3 month single-centre, single blind (clinical and laboratory examiners), parallel group randomised controlled two arm superiority trial. Fifty paediatric patients attending the Postgraduate Orthodontic Clinic at the Hamdan Bin Mohammed College of Dental Medicine (HBMCDM), Mohammed Bin Rashid University of Medicine and Health Sciences (MBRU), Dubai, United Arab Emirates, who meet the eligibility criteria will be recruited. Block randomisation with 1:1 allocation and concealment of allocation will be carried out. The treatment group will receive probiotic tablets containing Streptococcus salivarius M18 and Lactobacillus acidophilus together with regular oral hygiene versus the control group on regular oral hygiene alone. Clinical examination and collection of saliva for microbiome assay will be carried out at baseline and end of study. Self-reporting by patients will be used to document acceptability and adverse effects. Statistically significant decrease in gingival bleeding on probing in the treatment group will be classified as primary outcome of treatment success. Statistically significant reduction in Plaque Index, Gingival Index and shift in the composition of the oral microbiome in favour of beneficial bacteria are secondary outcomes indicative of efficacy of probiotic intake. ETHICS AND DISSEMINATION: Ethical approval for the study has been granted by the HBMCDM, MBRU, Institutional Review Board (Reference #: MBRU-IRB-2018-015). Study findings will be disseminated via publication in peer-reviewed journal. TRIAL REGISTRATION NUMBER: ISRCTN95085398.

A study protocol of a single-center investigator-blinded randomized parallel group study to investigate the effect of an acclimatization visit on children's behavior during inhalational sedation in a United Arab Emirates pediatric dentistry postgraduate setting as measured by the levels of salivary Alpha Amylase and Cortisol.

INTRODUCTION: Inhalation sedation is a proven safe method for reducing children's dental anxiety and has been used worldwide for decades. There is controversy regarding the use of acclimatization or familiarization visits for dental sedation treatment pathways for children. This may increase acceptance to the treatment based on desensitization and acclimatization principles underpinning many behavior management techniques. This study aims to identify whether, an inhalation sedation acclimatization visit is effective in reducing the stress level in anxious children as measured by salivary Alpha Amylase and Cortisol levels. METHODS: The study is a single-center, single blinded, parallel group 2 arm clinical trial. Children in need of inhalation sedation aged 5 to 15 years from September 2019 through March 2020 attending the Postgraduate Pediatric Clinic at the Hamdan Bin Mohammed College of Dental Medicine, in Dubai, will be allocated randomly and equally to either:At the initial visit a salivary sample will be collected at the beginning of the visit and the sedation need score will be recorded using the pediatric indicator of sedation need. Treatment for both groups will commence at the second visit. Salivary samples will be collected 15 minutes before the start of the treatment and 15 minutes after the conclusion of the treatment. The following outcomes will be recorded: completion of dental treatment, anxiety scores at baseline and after treatment using Frankl rating behavior scale and physiological anxiety related changes will be recorded using salivary Alpha Amylase and Cortisol levels. Mean changes of physiologic anxiety levels and corresponding 95% confidence intervals will be determined to compare the 2 treatments (sedation with familiarization and sedation without familiarization). DISCUSSION: This is will be the first study to measure the effect of the acclimatization visit of nitrous oxide inhalation sedation on the level of physiological anxiety and the behavior of the pediatric patients during treatment.

Oral Health Status among Children with Down Syndrome in Dubai, United Arab Emirates.

OBJECTIVES: The purpose of this study was to assess the oral health status in Down syndrome (DS) children in Dubai, United Arab Emirates. MATERIALS AND METHODS: A total of 106 DS children (mean age = 9.3 ± 2.8) and 125 healthy children (mean age = 11.7 ± 4.4) were recruited from both special needs centers and private/public schools in Dubai. A dental examination for decayed-missing-filled teeth (DMFT) in deciduous dentition/DMFT in permanent dentition indices, simplified oral hygiene index, calculus index (CI), were carried out. In addition, occlusal, dentofacial, soft-tissue abnormalities, and erosion were assessed. Statistical analysis was conducted using SPSS for Windows, version 20.0 (SPSS Inc., Chicago, IL, USA). RESULTS: The mean number of DMFT in DS children was significantly higher than that in healthy children. DS children in the primary dentition group had higher restorative index and Met Need Index scores than the control group. On the other hand, CI was found to be significantly higher among children with DS compared to healthy controls (P < 0.004). DS children had a significantly higher proportion of open bite and other occlusal problems. Class III molar angle malocclusion was significantly higher in DS (66%) compared to controls (11.2%). Erosion was significantly higher among DS children compared to healthy control (34% vs. 15.3%). CONCLUSIONS: DS children in Dubai had higher caries rate compared to healthy children. DS group received more restorations and dental treatment compared to the control group. More to add, DS children had significantly more calculus, erosion, and malocclusion problems.

Knowledge of Management of Traumatic Dental Injuries of Emergency Department Physicians and Residents in the United Arab Emirates.

Purpose: To investigate knowledge of emergency department physicians and residents (ED-Drs) about management of traumatic dental injuries (TDI) in the United Arab Emirates (UAE).
Methods: A cross sectional study of ED-Drs was conducted using a questionnaire and a score of TDI knowledge (TDI-K) was created (maximum of six). Statistical analysis was performed using chi-square, Fisher's exact, Mann-Whitney U, and Kruskal-Wallis tests, and significance was set as P <0.05.
Results: One hundred fifty-five physicians participated, with one-third reporting they encountered TDI more than once a week. Sixty percent of ED-Drs had received TDI education, of which a significantly higher proportion (84.4 percent) were Western-trained (P =0.007). Consultants and specialists had the highest knowledge scores (P =0.001). ED-Drs with five to 10 years' experience scored significantly lower (3.07±1.65) than those with less than five years of experience (3.86±1.36) and those with more than 10 years of experience (3.83±1.36, P=0.034). Only 38.2 percent of general practitioners (GPs) were confident placing sutures intraorally, compared to 80.6 percent of the consultants and specialists and 57.1 percent of the residents.
Conclusion: Overall knowledge of TDI and their management among ED-Drs across the UAE is inadequate. GPs had the lowest knowledge and confidence to manage TDI. (J Dent Child 2019;86(1):24-31)

Emergency Management of Traumatic Dental Injuries: Knowledge of Dubai School Nurses

Abstract Objective: To assess the knowledge of school nurses in Dubai, United Arab Emirates, about the emergency management of Traumatic Dental Injuries (TDIs) at schools. Material and Methods: A cross-sectional questionnaire survey was conducted amongst 68 school nurses (SN) prior to inviting them to an educational workshop on the emergency management of TDIs. The educational workshop covered all the topics in the questionnaire and provided basic necessary information to the SN regarding the emergency management of TDIs. Descriptive statistics were used to describe the characteristics of the sample; the Kolmogorov-Smirnov test was used to test normality for the score of knowledge and Mann-Whitney U test to correlate score of knowledge with different demographical variables (p<0.05) Results: An overall lack of knowledge about the emergency management of TDIs was observed. The overall average for the score of knowledge for all the participants was 10.75 out of a total of 16 correct answers. Female participants had significantly higher scores of knowledge compared to males (p=0.02). None of the other demographic variables were significantly associated with the score of knowledge Conclusion: More training programs are essential for school nurses to improve their knowledge and awareness for better future handling of traumatic dental injuries.

Referral Patterns of Pediatric Oral Surgery Cases: A Pilot Survey of United Arab Emirate Dentists

Objective: To assess the referral patterns of General Dental Practitioners (GDPs) and Pediatric Dentists (PDs) when faced with a range of Pediatric-Oral Surgery (POS) cases. Material and Methods: Eighty-two dentists treating children [51.2% GDPs (n=42) and 48.8% PDs (n=40)] were shown clinical photographs or radiographs of twelve common POS cases. Opinions on whether to "manage it yourself", "refer to a/another pediatric dentist", "refer to an oral surgeon (OS)", "refer to a multidisciplinary clinic (MDC)", or "do nothing" were sought. Statistical analysis was carried out using SPSS software with Chi-square test (p≤0.05). Results: Both GDPs and PDs reported significantly higher referrals to OS of: 1) lower lip mucoceles (50%, 52.5% respectively), 2) exposure of impacted maxillary canine (64%, 51.3%) and 3) dento-alveolar trauma cases (73.8%, 65%). A majority of GDPs and PDs reported self-managing of: 1) removal of multiple deciduous carious teeth (81%, 97.5%), 2) odontogenic infections with facial swelling (57.1%, 92.5%), 3) removal of ankylosed submerged primary molars (66.7%, 95%) and 4) dental trauma (71.4%, 100%). PDs reported self-managing primary herpetic gingivostomatitis (PHGS, 95%) compared to 45.2% of GDPs. GDP referral of PHGS to the PDs was 42.9%. There were no significant differences between both groups regarding removal of a mesiodens, release of a tongue-tie, a labial frenectomy, or a lip laceration, but the majority would refer to oral surgeons in these cases. Conclusion: Whilst United Arab Emirates dentists sampled referred some pediatric-oral surgery cases to oral surgeons, general dental practitioners were reluctant to refer pediatric-oral surgery cases to pediatric dentists, preferring to self-manage them.
