Pages 129-133IntroductionSevere Acute Respiratory Syndrome Coronavirus 2 (SARS-COV-2) disease can be transmitted through direct or indirect contact of droplets. The aim of this study was rapid review of personal protective equipments in the field of dentistry against coronavirus.MethodThis study was a rapid review and cross sectional research. A search was performed in Scopus and PubMed. The key words was PPE) personal protective equipment( with "Corona virus "OR "Coronavirus" OR "Covid 19" as well as the combination of "oral health" and "dent" with "Corona virus" OR "Covid 19" OR "coronavirus". Finally, we selected 9 articles and excluded 545 unrelated articles. We reviewed these 9 studies in full text and excluded 2 of them being unrelated to the review of personal protective equipment.ResultsA study showed that patients with Covid-19 who do not yet have symptoms may seek emergency treatment. Two researchers concluded that dentists had good information about how the virus was transmitted but did not know its symptoms well. A study concluded that the use of filtering face piece respirators (FFRs) during the Covid-19 epidemic is essential to prevent the transmission of aerosols and droplets, as it has been shown to be more fluid-resistant and better than surgical masks which cause flooding around the mouth and nose.ConclusionThis study shows that to some extent a significant number of dentists do not have enough information about the disease and proper personal protective equipment. This may be due to the lack of precise operating instructions.Keywords: Personal protective equipment, PPE, Coronavirus, COVID-19, dentist

Taurodontism is an anomaly that can cause problems in dental treatment. It is essential for clinicians to accurately determine the prevalence of this anomaly. This study aimed to determine the prevalence of taurodontism and its associated anomalies in patients visiting clinics in Kerman in 2019.
MethodsThis cross-sectional study was conducted on 424 digital panoramic radiographs of patients who visited private clinics in Kerman in 2019. The panoramic radiographs were evaluated for the presence of taurodont molars and possible related anomalies such as microdontia, severe hypodontia, as well as enamel and dentin hypoplasia. The statistical analysis was performed using SPSS 21 and chi-square test. The significance level was set at 0.05.
ResultsThe findings of this study showed there were 82 taurodont teeth in 33 (7.78%) out of a total of 424 panoramicradiographs (6.6% in males and 9.0% in females with an age range of 18-52(. There was no significant relationship between sex and taurodontism (P=0.36). Of 82 taurodont molars, 34.1% were in the mandible and 65.9% in the maxilla. The most involved teeth were the mandibular second molars. There was no significant relationship between maxilla and mandible concerning the infected teeth (P=0.74). Taurodontism and hypodontia were observed simultaneously in only one man who had 4 taurodont teeth.
ConclusionThe prevalence of taurodont molars in this study was 7.78% and it was more common in second molars and in the mandible. Moreover, hypotaurodontism was found as the most common type of anomaly.

Patient waiting time is an important factor in the management of the health sector. This study aimed to develop a suitable queuing theory and simulation technique to optimize dental hospital management.
MethodsA descriptive-analytical study was performed in a dental hospital in Tehran, Iran. A sample of 3364 patients referred to the hospital was selected to calculate the patient flow and queuing system performance. After an initial data assessment, the dental hospital queuing system performance indicators were calculated for two shifts. The queuing system of the current situationwas modeled using ARENA software, and two scenarios were examined.
ResultsThe average number of patients waiting in the queuing system was 38 and 17 in the morning and evening, respectively. The average time patients spend waiting in the system was 110 and 49 minutes in the morning and evening, respectively. The two scenarios, based on the simulated queuing network model, showed that in the first scenario, by using two nurses (one male and one female) as triage clerks for filing requests, one clerk for managing financial records, and one information desk secretary, the average queue length and waiting time were reduced to 0.02 patients and 4 minutes, respectively. In the second scenario, by using two nurses (one male and one female) as triage clerks for filing requests and two secretaries (one male and one female) for financial record management and registration, the average queue length and the waiting time in triage were reduced to 0.03 people and 5 minutes, respectively.
ConclusionBased on the results, using queuing theory and simulation techniques can improve the queuing status of health centers without any changes in the number of staff and only by implementing a suitable rearrangement in staff duties, establishing parallel service lines in busy service-providing centers, and using nurses able to multitask.

The internet is an important tool; however, there are concerns about the quality and reliability of medicalinformation available online. This study aimed to evaluate the quality and reliability of internet information on fissure sealants with different toolkits.
MethodsThis study was conducted by searching the internet using the Google search engine with questions about fissure sealants. The first thirty websites in search results for each question were evaluated. Videos, duplicate websites, and advertisements were excluded. A total of 270 websites were evaluated by the Journal of American Medical Association (JAMA) Benchmark and Health on the Net Code of Conduct (HONcode) certification.
ResultsThe results revealed that 35.1% of the websites met JAMA authorship criteria, 19.3% met JAMA attribution criteria, 42.1% met JAMA disclosure criteria, and 19.3% of websites met JAMA currency criteria. The websites from the United States and Australian websites showed the highest JAMA authorship criteria scores, respectively. Moreover, 8.8% of websites met HONcode criteria. One information, two government, and two organization websites met the criteria of this certification. None of the private clinic websites met HONcode criteria.
ConclusionThis study showed that the quality and the reliability of web-based information on fissure sealants in pediatric patients are generally inadequate. Both physicians and website editors should be careful and attentive when sharing information on the Internet.

This retrospective study aimed to investigate the distribution of root canal treatment (RCT) procedures performed on first permanent molars according to age, sex, mandible, maxilla, right jaw, and left jaw in a group of children.
MethodsThe records of RCT of a total of 6286 first permanent molar teeth of 5432 patients aged 8-16 years who visited the Department of Pediatric Dentistry, Faculty of Dentistry, Dicle University, Turkey from 2013 to 2018 were examined. Moreover, parameters such as age, gender, lower jaw, upper jaw, right jaw, and left jaw were evaluated. Frequency analysis and Pearson correlation test were used for statistical analysis and the level of significance was set at P<0.05.
ResultsThe results of this study indicated that most of the boys (31.97%) received RCT of the lower left first molar tooth and most of the girls (34.21%) received RCT of the lower right first molar tooth. The tooth most receiving RCT was the mandibular right first permanent molar (33.09%). The tooth least receiving RCT was the maxillary right first permanent molar tooth (16.59%). In general, RCT was performed on the maxillary jaw less than on the mandibular.
ConclusionRCT of first permanent molars showed variability according to age and position of jaws. RCT was performed more on the mandibular jaw than on the maxillary. It was observed that the incidence of RCT generally increased with age.

Dental trauma is highly frequent in children during school time and school teachers are often the first witnesses of the incident. This cross-sectional study aimed to assess the knowledge of school teachers about dental avulsion and its management.
MethodsThis cross-sectional questionnaire study was conducted on 782 primary and secondary school teachers in Malatya, Turkey. The questionnaire included three sections assessing (i) demographic characteristics, (ii), knowledge and attitudes about emergency management of avulsed permanent teeth, and (iii) teachers’ perspective on dental trauma education and selfevaluation of dental trauma knowledge. The correct answer scores were calculated according to section 2 (6 questions-17 items). Data were analyzed using Mann-Whitney U test, Kruskal-Wallis test, and multiple linear regression analysis.
ResultsThe correct answer score was calculated out of 17; the highest score was 13 and the mean score was 8.5. The level of knowledge on emergency management of avulsed teeth was higher among the teachers who had previously been trained on the subject.
ConclusionThe knowledge of Turkish school teachers about emergency management of avulsed teeth is limited. The findings obtained in this study indicated that an educational strategy for teachers is strongly required.

Dentine sensitivity presents as short, sharp pain due to exposed dentine. To keep ourselves abreast with thechallenging situation of increasing prevalence of dentine sensitivity within the country, this research was conducted to devise a better management strategy. The aim of this study was to evaluate the frequency and intensity of dentine sensitivity within patients reporting in Outpatient department (OPD) and to correlate good versus bad practices of dentine sensitivity patients with dentine sensitivity frequency.
MethodsA questionnaire based cross sectional study was carried out in three dental institutes of Lahore, Pakistan over a period of four months. A sample size of 300 individuals was selected by non-probability convenient sampling technique. Information collected included demographic data, participant’s oral hygiene practices and intensity of dentine sensitivity in them. A numeric rating scale was used to record the degree of dentine sensitivity and descriptive statistics were presented as frequency and percentage.
Results210 out of 300 patients reported dentine sensitivity (70%). Only 1/4th patients were highly qualified. 60% individuals were from low income group. 51% reported intensity as mild, 34% as moderate and 15% as severe sensitivity. Most common triggering factor was cold (36%). Good practices resulted in reduction in sensitivity.
ConclusionAccording to results, high frequency of dentine sensitivity is observed. More awareness needs to be created about factors leading to sensitivity focusing more on dietary patterns that cause erosive wear of enamel and reduction in aggressive brushing and parafunctional habits.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease can be transmitted through direct or indirect contact with droplets from the infected person’s respiratory system. The aim of this study was a rapid review of the use of personal protective equipment against coronavirus in the field of dentistry.
MethodsThis study was a rapid cross-sectional review and research. A search was performed in Scopus and PubMed. The key words were PPE) personal protective equipment) with “Corona virus” OR “Coronavirus” OR “Covid 19” as well as thecombination of “oral health” and “dent” with “Corona virus” OR “Covid 19” OR “coronavirus.” Finally, we selected nine articles and excluded 545 irrelevant articles. We reviewed these nine studies in full text and excluded two of them as they were unrelated to the review of personal protective equipment.
ResultsOne study showed that patients with COVID-19 who do not yet have symptoms might seek emergency dental treatment. Two researchers concluded that dentists had good information about how the virus was transmitted but did not know its symptoms well. One study concluded that the use of filtering facepiece respirators (FFRs) during the COVID-19 pandemic is essential to preventing exposure to aerosols and droplets, as it is more fluid-resistant and functions better than surgical masks, which cause flooding around the mouth and nose.
ConclusionThis study shows that many dentists do not have enough information about the disease and proper personal protective equipment. This may be due to a lack of precise operating instructions.
