Healthcare wastes are those generated inside healthcare services, including dental clinics. Workers coming into close proximity to hazardous healthcare waste are potentially at risk. In an attempt to assess the knowledge and attitudes of workers dealing with infectious waste, a questionnaire was administered. The biological risk was investigated by evaluating the microbial load and screening some clinically relevant micro-organisms in the nasal mucosa, hands and coats of these workers. The results showed that 66.6% of the study population had incomplete primary education. Only two workers have had their blood tested to confirm anti-HBs levels. Microbial load evaluation on hand surfaces of morning workers showed statistically significant lower microbial loads after the workday when compared with the beginning of the work period. It is important to highlight that some clinically relevant bacteria, such as Pseudomonas aeruginosa and Klebsiella pneumoniae were isolated from worker’s hands. This study revealed the need for more training programmes regarding awareness of safe waste disposal protocols and also the necessity of discussing vaccination and its implications. Data regarding microbial loads of the worker’s hands, mostly at the beginning of the workday when handwashing is recommended worldwide, emphasise that hygiene measures should receive more attention during training exercises.

Objective: Owing to the habit of consuming ready food among the citizens of Malaysia a study was conducted to evaluate 20 samples of canned soya milk for the presence of possible microbial content. The samples were collected randomly from shopping malls, restaurants and kiosk in Ipoh Malaysia. Methods: All samples collected across Ipoh, were subjected to test for presence bacteria in nutrient agar, blood agar and macConkey media. The possible microbial load was swapped from surface and soya milk content with a sterile cotton and streaked on nutrient agar, blood agar and macConkey culture media. The streaked petri plates were incubated for 48 hours at 37oC. Results: The study revealed negative microbial growth in all except two samples from the surface and soya milk content collected from a restaurant in nutrient agar and blood agar medium. The presence of microbes was conformed as gram positive staphylococcus sp. through gram staining. The positive growth may be imputed to poor storage condition at the restaurant. Conclusion: It can be computed from the study that the majority of the samples were free from bacterial growth, suggesting strong in house quality control mechanism at the processing unit and exquisite storage conditions in malls and kiosk suggesting that soya milk available in malls and kiosk are fit for human consumption.

Background: Knowledge is considered to be essential for developing healthy practices and preventing the main oral diseases. In some developing countries, women were at higher risk to develop these diseases. This study was conducted to evaluate women’s dental knowledge and practices through a specific questionnaire and the relationship with patient’s educational level and the number of their children. Subjects and method: Women, aged from 25-35 years old, were selected to participate in the current study. They were attending dental clinics in the teaching hospital of Baghdad University. Each participant was instructed to answer questionnaire sheet which is previously prepared in Arabic language by the authors. The total number of women was divided into three groups according to women’s educational level and the number of their children. Results: The number of women that participated in the study was 150. Higher percent of them (58.7%) have received instruction on the use of dental floss but 60.0% had no information about fluoride. Dental floss was used by only 24.7% of women. Higher percent of women eat candies, chocolate bars and cookies in between meals. Significant association was reported between educational level and oral health information. Educational level didn’t influence patients’ health practices. Frequency of follow-up appointments and toothbrushes changes were higher among women with less number of children. Conclusion: The study revealed important gaps in oral health practices especially in diet control and the use of dental floss. There is a need for frequent dental educational programmes among women to promote the proper practices and to achieve good oral hygiene.

BACKGROUND Gingivitis is a non-painful, inflammatory condition that can be treated with home remedies. Left untreated gingivitis can lead to tooth loss. Periodic dental examinations are important for early diagnosis and treatment of gum diseases. In order to contain the spread of the corona virus, governments, including in Israel, have restricted movements of their citizens which has caused routine dental checkups to be postponed. OBJECTIVE This study aimed to examine the ability of an mHealth app- iGAM to reduce gingivitis. METHODS A prospective observational cohort study was performed, 160 unpaid participants were divided into 2 equal groups and downloaded the iGAM app. Group 1 photographed their gums weekly for eight weeks. Group 2 photographed their gums at the time of recruitment and 8 weeks later. After photo submission, the participants received the message "It is recommended to read the information contained within the app regarding maintaining oral hygiene habits". A single blinded researcher examined the images and scored them according to the Modified Gingival Index (MGI). RESULTS The average age of group 1 was 26.77 (S.D. ± 7.43), and 28.53 (S.D. ± 10.44) for group 2. The majority were male (74.7% in group 1 vs. 66.7% in group 2), most participants described themselves as "secular", most were "single", non-smokers (74.7% vs. 78.4%) and did not take medications (85.3% vs. 78.4%). 126 subjects completed the study. A statistically significant difference (P <.001) was found in the dependent variable (MGI) in a linearly negative manner. As time passed, the gum condition improved, there were significantly lower gingivitis scores in group 1 (M = 1.16, S.D. ± 1.18) compared to group 2 (M = 2.16, S.D. ± 1.49), after eight weeks. Those with more recent dental visits had a lower MGI (p = .037). No association was found between knowledge and behavior, most participants were familiar with the recommendations for maintaining oral health, yet they only performed some. CONCLUSIONS A dental selfie taken once a week using an mHealth app (iGAM) reduced the signs of gingivitis and promoted oral health. During the current pandemic where social distancing recommendations may be causing people to avoid dental clinics, this app can remotely promote gum health. CLINICALTRIAL The protocol was approved by Hadassah research ethics committee (IRB, 0212-18-HMO)

Few studies have evaluated gender differences in young dentists’ career focusing on career breaks and return to work. We created a cohort dataset for dentists registered in 2006 using the national survey between 2006–2016 (men, 1680; women, 984), and examined the work setting of dentists by gender 10 years after registration. The proportion of dentists on career break increased each survey year, and was more pronounced in women than in men (2006 to 2016, men, 11.2% to 14.2%; women, 7.9% to 31.0%). The proportion of those who had career breaks between 2006–2016 was 44.8% in men and 62.9% in women. In the multiple logistic regression for examining the associations between those who returned to work compared to those working continuously, in women, the odds ratios (OR) were significantly higher in those working in dental clinics (owner, OR: 5.39; employee, OR: 3.10), and those working part-time (OR: 2.07); however, in men, there was no significant association with part-time work. These results suggest during early career phase, female dentists are more likely than males to take career breaks and choose part-time on returning. These gender differences should be considered for ensuring adequate workforce in dentistry in the future.

AbstractIn the past few decades, there have been remarkable advances in our knowledge of gold nanoparticles (AuNPs) and synthesizing methods. AuNPs have become increasingly important in biomedical and industrial applications. As a newly implemented method, AuNPs are being used in nanopackaging industries for their therapeutic and antibacterial characteristics as well as their inert and nontoxic nature. As with other NPs, AuNPs have privileges and disadvantages when utilized in the food sector, yet a significant body of research has shown that, due to the specific nontoxic characteristics, AuNPs could be used to address other NP flaws. In this mini review, we present synthesizing methods, food industry applications, and mechanisms of action of gold nanoparticles. Regarding the investigations, gold nanoparticles can play a major role to reduce microbial load in foodstuff and therefore can be implemented in food packaging as an effective approach.

The novel corona virus, Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), and the disease it causes, COVID-19 (Coronavirus Disease-2019) have had multi-faceted effects on a number of lives on a global scale both directly and indirectly. A growing body of evidence suggest that COVID-19 patients experience several oral health problems such as dry mouth, mucosal blistering, mouth rash, lip necrosis, and loss of taste and smell. Periodontal disease (PD), a severe inflammatory gum disease, may worsen the symptoms associated with COVID-19. Routine dental and periodontal treatment may help decrease the symptoms of COVID-19. PD is more prevalent among patients experiencing metabolic diseases such as obesity, diabetes mellitus and cardiovascular risk. Studies have shown that these patients are highly susceptible for SARS-CoV-2 infection. Pro-inflammatory cytokines and oxidative stress known to contribute to the development of PD and other metabolic diseases are highly elevated among COVID-19 patients. Periodontal health may help to determine the severity of COVID-19 infection. Accumulating evidence shows that African-Americans (AAs) and vulnerable populations are disproportionately susceptible to PD, metabolic diseases and COVID-19 compared to other ethnicities in the United States. Dentistry and dental healthcare professionals are particularly susceptible to this virus due to the transferability via the oral cavity and the use of aerosol creating instruments that are ubiquitous in this field. In this review, we attempt to provide a comprehensive and updated source of information about SARS-CoV-2/COVID-19 and the various effects it has had on the dental profession and patients visits to dental clinics. Finally, this review is a valuable resource for the management of oral hygiene and reduction of the severity of infection.
