Children and adolescents with good oral hygiene behaviours are likely to grow into adults with the same behaviours. This study assessed the frequency of using various oral hygiene methods among children and adolescents from different countries and individual, familial and country-level factors associated with the use of these methods. Methods A multi-country online survey collected data from caregivers of children in 2020-21 about children's use of oral hygiene methods including toothbrush, fluoridated toothpaste, mouthwash, dental floss and miswak using selfadministered, close-ended questions. Adjusted multilevel logistic regression models were used to assess the relationship between each of the five oral hygiene methods (dependent variables) and the independent factors: sex, age, and history of dental visits (individual factors), mother's education and area of residence (familial factors) as well as country income and region (country-level factors). Results A total of 4766 parents/caregivers were included from 20 countries (77.4% Eastern Mediterranean-region and 41.6% lower middle income countries). The most frequent oral hygiene methods were using toothbrush and toothpaste (90% and 60.3%). The use of oral hygiene methods differed by age, sex and history of dental visits as well as mother's education and area of residence (P < 0.05). In addition, children from low income countries had significantly lower odds of using mouthwashes and dental floss than those from high income countries (AOR = 0.55, 95% CI 0.31, 0.98 and AOR = 0.34, 95% CI 0.12, 0.97) whereas children from the European region had higher odds of using mouthwash (AOR = 2.82, 95% CI 1.27, 6.26) and those from the region of the Americas had higher odds of using dental floss (AOR = 3.84, 95% CI 1.28, 11.52) than those from the Eastern Mediterranean region. Conclusions The use of various oral hygiene methods is associated with individual, familial and country-level factors. Oral health promotion programs should be developed taking into account these influences.

A multi-country cross-sectional survey collected data from caregivers of children from August 2020 to February 2021. The questionnaire was developed guided by the framework of the Andersen's model of factors (predisposing, enabling and need). Multilevel logistic regression was used to assess the association between access-to-dental care problem and predisposing, enabling and need factors. A total of 4,843 caregivers from 20-countries reported on their children (52.3% males, mean age = 8.4 years) with 29.2% having access to care problem. A significantly greater percentage of caregivers from lower-middle-income countries (LMICs) than low-income countries (LICs), upper-middle-income countries (UMICs) and highincome countries (HICs) reported an access-to-dental care CONTACT Heba Mohamed Elkhodary

Methods This was a secondary analysis of data collected from adults in Nigeria between July and December 2020. The variables extracted included change in sexual activity, alcohol consumption and use of other psychoactive substances, COVID-19 preventive behaviors (wearing face masks, washing hands, physical distancing), anxiety, depression, post-traumatic stress disorder (PTSD) and sociodemographic variables (age, sex, education, HIV status, employment status). Multivariable logistic regressions were conducted. A model was run to regress depression, anxiety, PTSD, increased alcohol consumption, and increased use of other psychoactive substances, on increased sexual activit...

The aim of the study was to assess the relationship between emotional stress (COVID-19 related fear, anger, frustration, and loneliness) and the use of coping strategies among adults in Nigeria during the COVID-19 pandemic. Methods Data from adults aged 18 years and above were collected through an online survey from July to December 2020. The dependent variables were COVID-19 related fear (fear of infection and infecting others with COVID-19), anger, frustration, and loneliness. The independent variables were coping strategies (use of phones to communicate with family and others, video conferencing, indoor exercises, outdoor exercises, meditation/mindfulness practices, engaging in creative activities, learning a new skill, following media coverage related to COVID-19) and alcohol consumption. Five logistic regression models were developed to identify the factors associated with each dependent variables. All models w...

Hence, more studies are needed to better determine the efficacy and clinical outcomes of these systems. This study aimed to assess radiographic bone gray-scale values changes around the newly-designed compressive implants after immediate loading. A prospective clinical study was carried out. 10 compressive implants were placed in patients having missing teeth in the posterior region of the mandible. Cone-beam computed tomography (CBCT) was used to follow-up patients immediately, 6 months, and 12 months postoperatively. Grey-scale values from the CBCT images were implemented as indicators for bone density around dental implants. Changes in grey-scale values around the implants were evaluated from the buccal, lingual, mesial and distal implant sides. An increase in the average values of bone density around implants was observed throughout all studied periods, and these findings were more significant after 6 months post-surgically. In conclusion, the compressive threads and tapered design of compressive dental implants allowed forming a highly dense bone around the implant, and high primary stability was achieved, which in turn contributed to the overall success of these implants in immediate loading.

This cross-sectional survey reports on factors associated with an increase in alcohol drinking and tobacco use during the COVID-19 pandemic. METHODS An online survey conducted in 2020, generated data from 14899 adults residing in 105 countries. Dependent variables were changes in alcohol drinking and tobacco use. Independent variables were age, sex, education level, job loss, lost or reduced wages, investment/retirement benefits, interrupted substance addiction care, and income level of the countries. Multilevel logistic regression analysis was computed to explore the associations between dependent and independent variables in adjusted models using the backward stepwise method. The probability of including or excluding a covariate was set at p(in)<0.05 and p(out)>0.1, respectively. RESULTS Of the regular alcohol consumers (N=4401), 22.9% reported an increase in their alcohol drinking. Of the regular tobacco users (N=2718), 31% reported an increase in their tobacco use. Job loss (Alcohol: AOR=1.26; Tobacco: AOR=1.32) and lost/reduced wages (Alcohol: AOR=1.52; Tobacco: AOR=1.52) were associated with higher odds of increased alcohol drinking and tobacco use. Many interruptions to addiction care (AOR=1.75) were associated with higher odds of increased alcohol drinking. Whereas no interruption to addiction care was associated with lower odds of increased alcohol drinking (AOR=0.77). Also, none (AOR=0.66) or some (AOR=0.70) interruptions to addiction care were associated with lower odds of increased tobacco use. CONCLUSIONS This global survey alludes to the unintended consequences of the current COVID-19 pandemic on alcohol drinking and tobacco use. It is critical that the strategies for emergency responses should include support to ameliorate the impact of financial distress and disruption in substance dependence treatment services.

It provides a broad observation of the maxillomandibular complex at a lower cost and radiation dose. But cone-beam computed tomography (CBCT) examination, after panoramic radiograph evaluation, can produce a change in the diagnostic thinking of maxillofacial surgeons leading to alterations in treatment plans. Objective: We aim to report a case with incidentally discovered radiographic findings where diagnostic changes were caused by switching from panoramic to CBCT imaging. Conclusion: Radiographic assessment of the position and angulation of screws by panoramic x-ray should be approached with extreme caution. The image of choice is CBCT if nerve injury is suspected.

There is, however, little known about oral diseases associated with COVID-19 in adolescents and young adults (AYA). Therefore, the aim of this study was to assess oral lesions’ association with COVID-19 infection in AYA; and to identify if sex and age will modify these associations. Methodology Data was collected for this cross-sectional study between August 2020 and January 2021 from 11-to-23 years old participants in 43-countries using an electronic validated questionnaire developed in five languages. Data collected included information on the dependent variables (the presence of oral conditions- gingival inflammation, dry mouth, change in taste and oral ulcers), independent variable (COVID-19 infection) and confounders (age, sex, history of medical problems and parents’ educational level). Multilevel binary logistic regression was used for analysis. Results Complete data were available for 7164 AYA, with 7.5% reporting ...

Methodology: Participants with anterior mandibular fractures were randomly assigned into the two groups of this partially-blinded randomized clinical study. The mandibular fractures were managed via standard technique. Simvastatin-loaded gelatin sponge was locally applied along the fracture line after open reduction and internal fixation and before suturing in the study group. Only saline with gelatin sponge was used as a placebo in the control group. Participants were radiographically followed up after 1 week, 2 months, and 4 months. CBCT images were used to measure grey-scale values, and to indicate fracture union at the 2-month and 4-month follow-ups. Results: 24 anterior mandibular fractures (n=24) were included in all stages of this study. Mean participants age was 30.8 (± 11.7) years. Comparisons showed significant differences in mean grey-scale values at 2-month (P=0.022) and 4-month (P=0.009) follow-ups between the simvastatin and control groups. Differences regarding fracture union between the simvastatin and control groups were insignificant after 2 months (P=0.273), but significant after 4 months (P=0.003). Conclusion: It can be concluded that local application of 10mg simvastatin with gelatin sponge carrier along the fracture lines may hasten the bone healing in mandibular fractures.

The complex etiopathogenesis of the temporomandibular disorders (TMDs), and the variability of symptoms make it difficult to adopt standardized therapeutic protocols. Recently, platelet-rich plasma (PRP) injections have been applied into the TMJ in patients with TMJ osteoarthritis. On the other hand, arthrocentesis has received a widespread acceptance, as a minimally-invasive surgical procedure for TMDs. This study aimed to assess and compare the effect of each of these protocols (arthrocentesis, PRP injection, combination of them) in the management of TMJ osteoarthritis. Methods A single-blinded randomized clinical trial was conducted on a sample of 33 participants with limited mouth opening, pain on function and joint sounds due to TMJ osteoarthritis. Participants were assigned randomly into three groups: Arthrocentesis with PRP group; PRP group; Arthrocentesis group. Maximum mouth opening (MMO), pain and joint sounds were re-evaluated during a six-month observation period. Intra-and inter-group comparisons regarding these variables were performed. Results Participants in all study groups showed statistically significant improvement in terms of MMO and pain during the six-month postoperative period (p<0.05), and showed no significant improvements regarding joint sounds (p>0.05). Pain evaluations showed better outcomes in arthrocentesis with PRP group in comparison to arthrocentesis or injectable PRP alone after six months of follow-up (p<0.05). There were no significant differences in the outcomes of MMO and joint sounds evaluations between the three groups after six months. Conclusions Within the limitations of this study, it can be concluded that the three assessed treatment protocols were effective in improving limited mouth opening and pain in patients with TMJ osteoarthritis. A combination of TMJ arthrocentesis and PRP intra-articular injections showed the best outcomes regarding pain symptoms. None of the tested treatment protocols showed improvement in terms of articular sounds.

Methods This survey collected data electronically between June 29 and December 31, 2020 from a convenient sample of 5050 adults 18 years and above living in 12 West African countries. The dependent variables were: social distancing, working remotely, difficulty obtaining face masks and difficulty washing hands often. The independent variables were self-reported depression, having a health risk for COVID-19 (high, moderate and little/no risk), living with HIV and COVID-19 status (SARS-CoV-2 positive tests, having COVID-19 symptoms but not getting tested, having a close friend who tested positive for SARS-CoV-2 and knowing someone who died from COVID-19). Four binary logistic regression models were developed to model the associations between the d...
