Oral Healthcare Services Delivered During COVID-19 Lockdown: A Report from Eastern Mediterranean Region

ABSTRACT Objective: To describe oral healthcare services administered during the lockdown in the Eastern Mediterranean region and to investigate the role of socio-professional characteristics of dental practitioners or their self-reported COVID-19 infection. Material and Methods: A questionnaire was distributed to dental practitioners in all healthcare sectors in Jordan, Egypt, and Saudi Arabia. Results: There was a total of 335 participants, with the majority being females (N=225, 67.2%) and general practitioners (N=202, 60.3%). Cellulitis was the most common emergency encountered (N=108). The most common urgent procedures were for pulpitis, abscesses, and pericoronitis (N=191, 130, and 95, respectively). Country-specific significant associations were pulpitis in Egypt and Jordan, broken symptomatic teeth in Jordan, and biopsy in Egypt (p<0.05). The Ministry of Health was significantly associated with the management of dental infections, avulsion, and orthodontic emergencies, while university hospitals were significantly associated with advanced restorative procedures (p<0.05). Male practitioners performed significantly more procedures, particularly surgical emergencies (p<0.05). Conclusion: Dental infections were the most common complaints among dental patients during lockdown. Countryand sector-specific dental procedures are detected. Male gender seems to play a determinant role in performing a higher number of procedures, particularly for surgical emergencies (AU).

Getting to Know SARS-CoV-2: Towards a Better Understanding of the Factors Influencing Transmission

Abstract In November 2002, a virus known as SARS-CoV was identified in Guangdong, China, and it was implicated as the etiology of severe acute respiratory syndrome. Seventeen years later, in the same month of November, a similar disease with more dramatic outcomes was identified in neighboring Wuhan. It has been six months since the identification of first cases of COVID-19 pandemic; however, unveiling clinical characteristics and modes of transmission of the disease are taking longer than expected. This overview aims to highlight some important points regarding the mode of transmission for which continuously surprising facts are being revealed every day. We also raise some vital questions to alert the scientific community to find the right answers and minimize the drastic fatal outcomes of this disease. It can be stated that SARS-CoV-2 could be transmitted as aerosol infection as well as through contacting infected surfaces. The possible role of abdominal gases as a route of spread of the virus should be considered and a fecal sample might be a useful diagnostic tool. Moreover, medical face masks are not protective from virus transmission during treating COVID-19 patients in settings where aerosol-generating procedures are performed. Doffing of PPE for healthcare workers needs more attention as this might be a source of infection unless additional measures of PPE disinfection are employed before doffing.

Knowledge and Attitudes Towards Antibiotic Prescribing Among Dentists in Sudan

Objective: To evaluate antibiotic prescribing practices of dentists working in a major teaching hospital in Sudan, and to assess the need for establishing education programmes to enhance dentists' awareness of antibiotic use. Material and Methods: A cross-sectional study was carried out by distributing an anonymous self-administered questionnaire to a convenience sample of dental practitioners at major teaching hospital in Khartoum/Sudan. The questionnaire investigated knowledge and attitudes of participants in relation to antibiotic prescribing in dental practice. Results: One hundred out of 135 dental practitioners working at the hospital participated in the survey with 48 males and 52 females. Most of the participants (N=44) did not specify their preferable drug reference, while 32 participants specified British National Formulary, and the practice was significantly associated with a higher professional rank (p<0.001). Metronidazole was the most frequently cited antibiotic for dentofacial infections (N=73) and Acute Necrotizing Ulcerative Gingivitis (N=56), while amoxicillin was the most frequently cited antibiotic for dento-alveolar infections and infective endocarditis prophylaxis (N=88 and N=47, respectively). Conclusion: Undergraduate, as well as postgraduate courses,, are required in Sudan to provide up-to-date orientation on antibiotic use, and to increase awareness of dentists about antibiotic prescribing.

Antibiotic Self-Medication for Oral Conditions: Characteristics and Associated Factors

Objective: To investigate the prevalence and contributing factors of antibiotic selfmedication for oral conditions in dental patients. Material and Methods: A questionnaire was distributed to 501 patients attending Taibah University Dental College and Hospital, Al Madinah, Saudi Arabia during late 2016. Questions were on socio-demographic characteristics, and pattern of antibiotic self-medication for oral disease. Statistical analysis was performed using IBM SPSS software version 21. Statistical significance level was set at p ≤.05. Results: Age range was 15-64 years (29.08±9.32 years) with 297 females (59.3%) and 204 males (40.7%). 135 patients (27%) self-medicated with antibiotics for oral disease. This practice was statistically significantly associated with the older adults (p=0.001), lack of medical or dental insurance (p=0.014 and 0.007, respectively), and poor dental attendance (p=0.021). A number of 26 (25.7%) perceived analgesics as antibiotics. Amoxicillin-clavulanic acid was the most commonly cited antibiotic by 18 patients (17.8%). Dental pain was the most frequently reported oral condition. Pharmacists were the most common source for antibiotic prescription cited by 58 (57.4%). Conclusion: Antibiotic self-medication for oral disease is associated with the use of broad-spectrum antibiotics for non-indicated clinical oral conditions. The practice was encouraged by lenient behavior of pharmacists, lack of health insurance, and poor dental attendance.

Arabic Coffee as a Potential Alternative to Black Coffee in the Post- Bleaching Period: An in-vitro Study

Objective: To investigate the effect of Arabic coffee on bleached teeth in comparison to black coffee. Material and Methods: Forty teeth (sound maxillary or mandibular premolars with no carious lesions) were randomly selected into 4 groups (A, B, C and D). One group (A) did not receive bleaching and was incubated in saline. The second group (B) was bleached and then incubated in saline. The last two groups were bleached and were immersed in either Arabic coffee (C) or black coffee (D). Color recording of the samples was always carried out as near to their mid-buccal surfaces as possible using VITA Easyshade Advance System. Color measurements were carried out using a digital spectrophotometer at baseline and after short-term and long-term immersion. Data were subjected to two way ANOVA and T-test. The level of significance was set at was set at 0.05. Results: Results show that immersion in Arabic coffee resulted only in significant reduction in the b* color value upon long-term immersion (i.e. a reduction in the yellow hue). Black coffee on the other hand resulted in significant: reduction in lightness, increased red tint and increased yellow hue altogether. Conclusion: The use of Arabic coffee did not deteriorate color, with the only significant change being the reduction of yellowish hue. Arabic coffee could be an alternative to black coffee after bleaching.

The mental foramen II: radiographic study of the superior-inferior position, appearance and accessory foramina in Iraqi population / El foramen mental II: estudio radiográfico de la posición superior-inferior, aspecto y forámenes accesorios de una población Iraquí

Accurate information regarding the vertical location and appearance of the mental foramen, and the presence of accessory foramina, can have clinical significance, such as reducing complications that may occur during many oral surgical procedures involving the mental area. Geographic variations were reported in these variables. The aim was to evaluate the above-mentioned variables in an Iraqi sample. Five hundred eighteen panoramic radiographs of a random Iraqi sample (257 males, 261 females, average age= 46.5 years) were evaluated with regard to the above-mentioned variables, as well as the symmetry of the foramen regarding these variables. The area below the apices of mandibular premolars, and the continuous type were the most frequent vertical location and appearance of the mental foramen, respectively. Age advancement was found to be associated with an increase in the frequency of more inferior positioning and continuous appearance. The vertical position and appearance were asymmetrical in 16.2 % and 20.1 % of cases, respectively. Symmetry in the vertical location was statistically significant between sexes (P= 0.035), and young and old ages (P= 0.000). Symmetry in the appearance was found statistically significant (P= 0.025) only between the two age groups. Accessory foramina were recorded in 7.3 % of cases. The most common vertical location and appearance of the mental foramen on panoramic radiographs in this group are below the apices of mandibular premolars, and continuous type, respectively. This is in consistence with the findings of previous studies on other populations. The mental foramen usually has symmetrical vertical location and appearance. Accessory foramina are recorded in a percentage lower than that recently reported in some regional countries.

La información precisa acerca de la localización vertical, apariencia del foramen mental y la presencia de forámenes accesorios, puede tener importancia clínica, como la reducción de las complicaciones que pueden ocurrir durante muchos procedimientos quirúrgicos orales relacionados con el mentón. Las variaciones geográficas fueron reportadas en estas variables. El objetivo fue evaluar las variables anteriormente mencionadas en una muestra iraquí. Fueron evaluadas 518 radiografías panorámicas de una muestra aleatoria de Irak (257 varones, 261 mujeres, edad media = 46,5 años) con respecto a las variables antes mencionadas, así como la simetría del foramen con respecto a estas variables. El área por debajo de los ápices de los premolares mandibulares y el tipo continuo, fueron la localización vertical y apariencia del foramen mental más frecuentes, respectivamente. La edad avanzada se asoció con un aumento en la frecuencia de posicionamiento más inferior y de apariencia continua. La localización vertical y la apariencia fueron asimétricas en 16,2 % y 20,1 % de los casos, respectivamente. La simetría en la localización vertical fue estadísticamente significativa entre sexos (p= 0,035), y entre jóvenes y viejos (P= 0,000). La simetría en apariencia sólo fue estadísticamente significativa (p= 0,025) entre los dos grupos de edad. Se registró presencia de forámenes accesorios en un 7,3 % de los casos. La localización vertical del foramen mental más común en las radiografías panorámicas de este grupo están por debajo de los ápices de los premolares mandibulares, y respecto a la apariencia, el tipo continuo fue el más común. Esto está en coherencia con los resultados de estudios anteriores en otras poblaciones. Los forámenes mentales tienen una localización vertical y apariencia que suelen ser simétricas. Los forámenes accesorios se registran en un porcentaje inferior al informado recientemente en algunos países de la región.

The mental foramen I: radiographic study of the anterior-posterior position and shape in Iraqi population / Foramen mental I: estudio radiográfico de su posición antero-posterior y forma en población iraquí

Accurate information regarding the horizontal location and shape of the mental foramen can have clinical significance, such as reducing complications that may occur during maxillofacial surgical procedures involving the mental area. Geographic variations were reported in these variables. The aim was to study the horizontal position and shape of the mental foramen, as seen on panoramic radiographs of an Iraqi sample, to assess difference in these variables between sexes and age groups, and to assess symmetry of the mental foramen. 518 panoramic radiographs of a random Iraqi sample (257 males, 261 females, average age=46.5 years) were evaluated with regard to the horizontal location, shape and symmetry of the mental foramina. The area between the long axes of the two mandibular premolars, and the round type were the most frequent horizontal location and shape of mental foramen, respectively. Age advancement was found to be associated with an increase in the frequency of more posterior positioning and irregular shape. The horizontal position and shape were asymmetrical in 21.6% and 31.6% of cases, respectively. The Symmetry in horizontal location and shape of mental foramina were found statistically significant between sexes (P=0.041), and between young and old age groups (P=0.001), respectively. The most common horizontal location and shape of the mental foramen on panoramic radiographs in this group are between the two premolars, and the round type, respectively. This is in consistence with the findings of previous studies on other populations. The mental foramina have usually symmetrical horizontal locations and shapes.

Información precisa sobre la ubicación horizontal y forma del foramen mental puede tener importancia clínica en la reducción de complicaciones durante procedimientos quirúrgicos maxilofaciales que involucran el área mental. Fueron reportadas variaciones geográficas en relación a estas variables. El objetivo fue estudiar la posición horizontal y forma del foramen mental, a partir de 518 radiografías panorámicas de una muestra aleatoria en sujetos de Irak (257 varones, 261 mujeres; edad media= 46,5 años), quienes fueron evaluados con respecto a la posición horizontal, forma y la simetría de los forámenes mentales. En individuos de edad avanzada se encontró una asociación con un aumento en la frecuencia de un posicionamiento posterior y con forma irregular. La posición horizontal y forma del foramen fueron asimétricos en 21,6% y 31,6% de los casos, respectivamente. La diferencia hallada en relación a la simetría en posición horizontal y forma de los forámenes mentales fue estadísticamente significativa entre sexos (p=0,041), y entre los grupos de edad jóvenes y mayores (P=0,001), respectivamente. Se encontró con mayor frecuencia la posición horizontal entre los ejes longitudinales de los dos premolares mandibulares, y la forma circular, en relación a la posición antero-posterior y forma del foramen, respectivamente. Estos fueron resultados similares a estudios anteriores sobre otras poblaciones. Los forámenes mentales son simétricos, respecto a su ubicación horizontal y su forma.

The Use of Unconventional Substances and Tools in Narghile Smoking; a Pilot Study in Jordan.

Aims: Narghile smoking may be associated with a number of unconventional practices that need to be thoroughly investigated for their potential health problems. We investigated the prevalence and pattern of unconventional practices related to narghile smoking including the use of medications, fruits, and alcohol, among a sample of café patrons. Place and Duration of Study: A few cafés at Amman, Jordan during July 2011. Methodology: This was a cross-sectional survey whereby a pre-prepared questionnaire was distributed to a sample of café patrons. Questionnaire included demographic information, history of tobacco use, pattern of narghile smoking including unconventional practices and lastly health awareness and attitudes towards cessation. Results: Out of 96 café patrons, 61 (63.5%) agreed to participate with 42 males and 19 females. Age range was 16-64 years (mean=27.5±9.2). About 47.5% used fruits as the narghile head and 16.4% used fruits as water tank. Equal proportions (9.5%) of the sample added either milk/soft drinks to tank or added drugs to tobacco mix or the liquid contents of the tank. Conclusion: Narghile smoking may be associated with unconventional practices like the use of psychoactive drugs and alcohol. Further research is needed to explore the reasons behind this trend, and the associated potential health hazards.
