The emergence and spread of SARS-CoV-2 has increased environmental disinfectant usage to reduce the transmission of this virus. Ethanol 70-90% and 5% sodium hypochlorite have the highest consumption for disinfection of various environmental surfaces during the COVID-19 pandemic. Dental unit waterlines (DUWLs) are more susceptible to microbial contamination due to their particular structure. This study aimed to investigate the effect of increasing the use of disinfectants during the COVID-19 pandemic on the bacterial contamination of DUWLs.

During November (before the COVID-19 pandemic) and December (during the COVID-19 pandemic), a questionnaire was used to assess the frequency of disinfection of unit surfaces and other environmental surfaces and the type of disinfectants used. The water samples were collected from different parts of DUWLs. The gram staining method followed by the biochemical method was used to identify the desired bacteria.

The results showed that the frequency of disinfection of dental units increased 8 times in December compared to November. There is a significant inverse relationship between the frequency of disinfection of dental units surfaces and the bacterial contamination of dental unit waterlines.

The microbial load in different parts of the DUWLs was less than 200 CFU/mL. The American Dental Association (ADA) recommended and indicated the allowable microbial concentration and the appropriate quality and water used in these units.

The dental clinic has for a long time been considered as a risky place for infection dissemination. Due to aerosol generating procedures, the risk of cross-transmission in dental clinics has recently risen. Open dental clinics should undergo present-time reassessment concerning infection control, in particular, to consider the implications of the SARS-CoV-2 pandemic for today’s advanced technological and medical practices. It might be necessary to make urgent and appropriate modifications to the design of air circulation systems in the dental environment to prevent microbial transmission.

In order to minimise cross-transmission in multi-chair dental operatories, we have designed two model ventilation systems with 12 and 36 air change/hour capacities and with laminar airflow direction. The conditioned air directly blows into the dental treatment units, especially into the aerosol generating area, where the contamination is more concentrated. We hypothesise that these new designs could serve to isolate dental treatment units to function separately like closed dental operatories while keeping them open to each other.

Thorough physical and biological investigations will be required to determine how these designs can be applied effectively in terms of the required spatial separation of dental treatment units in the open multi- chair dental operatories.

Self-medication with antibiotics may increase the risk of inappropriate use and development of antibiotic-resistant bacteria. The aim of this study was to determine the prevalence of self-medication with antibiotics amongst dental outpatients in Iranian population.  Methods and Materials: One thousand and two hundred of dentistry patients, who were referred to dental school clinics in ten major provinces of Iran, participated in this study. A valid self-administered questionnaire regarding self-medication with antibiotics in case of dental pain was used to collect data. Data were analysed using descriptive statistics and Logistic regression analysis.

In our study population, the prevalence of self-medication was 42.6%. Amongst the Iranian cities, the highest prevalence of self-medication with antibiotics belonged to the city of Bandar Abbas (64%) and the lowest was seen in the city of Kerman (27.3%). Men were more likely to take antibiotics. Amoxicillin was the mostly used antibiotic. Severe pain, previous self-medications and high costs of dental visits were the most common reasons for self-medication with antibiotics in the investigated population. In addition, the present study showed that marriage, acceptable financial status and high level of education could decrease self-medication with antibiotics.

In the current investigation, an alarming fact was that self-medication for dental problems seemed very common amongst the studied population. One of its most important consequences was bacterial resistance. Therefore, there should be plans to promote and prioritize public health awareness and encourage general public’s motivation to reduce the practice of self-medication.Keywords: Antibiotics; Dental Clinics; Prevalence; Self-medication

Becoming completely edentulous is a major concern of dentists and other health care providers. It mostly targets aged population and has numerous comorbidities. An old-fashion but currently used treatment plan for edentulism is the complete denture method. In this study, we aimed to investigate the time when older people in Iran are in need of complete dentures and the reasons for tooth loss in this country. 

The medical records of 200 patients were collected from Shahid Heidari dental clinic for the study. Patients were completely edentulous and treated with complete dentures for the first time. Their systemic disease, periodontitis and smoking status were analyzed at a significance level of P<0.05.

The Mean±SD age for becoming edentulous was 52.1±1.07 years. Most populated age group was 45-50 and 55-60 years. Systemic disease and periodontitis was reported more in younger patients, while most of those who smoke aged more than 52 years.

It can be concluded that  the mean age of becoming edentulous in Iran is significantly lower than in other countries and more studies are required to assess the current status of edentulism in Iran. There is also a need for implementing an enhanced dental care plan for Iranian elderly population.

The presence of toxic and pathogenic agents in the dental waste products has made it to be classified as “hazardous waste.”
To assess dental waste production rate and composition and approaches used to manage these waste products in 2017 in Birjand, Iran.
48 dental clinics were evaluated in two months of 2017. Sampling was performed from each clinic 3 times a week. Samples were manually divided into 5 categories of chemical-pharmaceutical, infectious, semi-household, sharp and cutting materials, and toxic waste products, and weighed. A checklist containing 25 questions was used to evaluate the aspects of waste management in dental clinics.
The total amount of waste products generated in dental clinics was 7848.02 kg/ year in which semi-household waste had the highest quantity (4263.411 kg/year) and toxic waste had the lowest quantity (9.275 kg/year). Components with the highest amounts in dentistry waste products were nylon gloves (16.7%), paper and cardboard (13.4%), latex gloves (10.8%), and pharmaceuticals (10.2%). Waste separation was restricted to sharp and cutting waste. More than half (57%) of dental units were equipped with amalgam filter. Fixing solutions were directly discharged to sewage in 48.6% of clinics. There was no program to reduce waste generation in 54% of the clinics. Autoclave was the main tool for sterilizing dental instruments.
This study showed a remarkable share of recyclable materials in the composition of dental waste and lack of special approach to manage waste in dental clinics. It is necessary to plan for minimizing generation of, separating, and recycling waste at source.

The expansion of activities and performance areas of organizations, modern management issues mean that organizations are no longer satisfied with success in only a limited number of indicators. Mathematical models thus formed and gradually are developed for the assessment of organizations and provide the right tools. This study is conducted to provide a model for improving the quality of dental services in uncertain settings.
The study population in this study consists of two groups. The first group consisted of all the patients with at least one visit to the dental clinic of Guilan University of Medical Sciences in Rasht, 422 of whom were randomly selected through convenience sampling. These data were used for the IPA. The second group of experts consisted of 20 organizational directors and senior experts selected for the localization of the quality of services the dental clinic and the ISM. This applied descriptive-analytical study uses the Fuzzy Delphi method for selecting the components of the quality of services, the Importance-Performance Analysis (IPA) for identifying the strengths and weaknesses of these components, and the Interpretive-Structural Modeling (ISM) for improving the components of the quality of services by prioritizing the effectiveness of the factors.
The dental clinic of Guilan University has to pay immediate attention to including providing services as promised, the delivery of services with care, timely responding, the personnel’s greater efforts for solving the patients’ problems, a consistent quality of services, the speed of services, in order to improve the quality of its services.
The ISM showed that there are six levels of influential factors, with the two variables of “providing services as promised” and “equipment and technology” acting as the cornerstone of the model that should be emphasized first and foremost for the system to begin functioning.

Medical consultations have an important role in dental diagnosis and treatment planning, and are indicated for patients with uncertain medical histories. The purpose of the present study was to evaluate the medical consultations conducted for a group of patients in need of dental treatments. in this cross-sectional study, 173 medical consultation requests were reviewed at the diagnosis and oral medicine department of the dental school of Kerman University of Medical Sciences during 2014-2015. The demographic data, reasons for consultation, and medical precautions were descriptively analyzed. The mean age of the patients was 37.3±6.5 years, and 64.2 % of the subjects were females. The main reasons for medical consultations were hypertension (28.9 %) and cardiovascular assessment (19.7%). The main dental concerns included the need for preoperative antibiotic prophylaxis (7.5%) and the use of local anesthesia without epinephrine (19.7%). Medical consultations reduce the medical risks associated with dental procedures and unnecessary antibiotic prophylaxis. Good communication between dentists and physicians is essential for satisfactory patient care

Evidence-Based Dentistry (EBD) is very limitedly known in Iran, and has been defined as an approach to oral healthcare that requires the judicious integration of systemic assessments of clinically relevant scientific evidences, related to patient’s history and oral and medical conditions, with dentist’s clinical expertise and patient’s treatment needs and preferences. (1-5) The EBD is a popular medical field worldwide, involving the utilization of the results of clinical dental research that improves decision-making procedures to render the best treatment available to patients, determining the highest-quality treatment methods.

 The purpose of this study was to investigate the composition of dental waste coming from six dental health services in Isfahan, Iran. 

 From 45 public dental clinics in Isfahan, six public dental health services were selected (three dental clinics and three dental centers). Waste collection took place from October to December 2011. During this period, three samples were collected from each dental clinic and were divided to pre-determined groups manually. 

 In dental centers, the amount of infectious, non-infectious and domestic-type waste accounting for 45.07%, 12.15% and 42.78%, respectively. Whereas in dental clinics the production rates of infectious, non-infectious and domestic-type waste accounting for 52.2%, 8.58% and 39.22%, respectively. 

 Overall, according to the results it can be said that integration of infectious and hazardous waste with general waste leads to the amount of infectious waste appears much greater than it actually is. The collection and disposal of amalgam and other hazardous dental solid waste should be regulated as soon as possible and to decrease the costs of dental waste management the uncontaminated recyclable items, which contained approximately 33% of total dental waste should be recycled or reused if possible.
