“…This suggests that mask contamination through an unexpected route may cause secondary infection. Therefore, it is recommended that masks that have undergone a photosterilization process 27 with the use of ultraviolet (UV) irradiation, 28 which is widely used in dentistry and does not cause damage to the mask or filter, be used.…”

Background. Many patients are clinically consulted in dental clinics, where aerosol-generating procedures are widely used. In our previous study, we evaluated the temperature, humidity and contamination rates on the inner layer of masks according to the mask-wearing time. However, it is important to assess the contamination rates on the outer layer of masks used in dentistry as well. Previously, while examining the contamination rates, we only identified the associated bacteria; no detailed analysis of bacterial species depending on the mask-wearing time was conducted. Furthermore, we did not evaluate factors that could contribute to the contamination of masks.Objectives. The present study was intended to supplement the limitations of our previous study. Material and methods.The used masks were collected. Thereafter, colony forming unit (CFU) quantification and 16S rDNA sequencing were performed to calculate the contamination rates and identify bacterial species. Data on the participants' medical and dental history was collected. The participants filled out a questionnaire and underwent saliva tests.Results. On the inner and outer layers of the masks, 3.3 × 10 8 and 8.5 × 10 8 CFUs were found, respectively. The contamination rates of the masks increased with the increasing mask-wearing time. There was no correlation between the contamination rate on the inner layer and other factors, such as the probing depth (PD) ≥4 mm, the bleeding rate, the calculus rate, and saliva characteristics. The inner layer contamination rate increased as the number of treated teeth increased, and as the saliva buffering capacity decreased. The outer layer contamination rate increased with the number of times the mask was touched.Conclusions. The contamination rates were higher on the outer layer than on the inner one, and the CFU count increased with the mask-wearing time. The following bacterial species were found on the masks: Staphylococcus epidermidis (S. epidermidis); Staphylococcus aureus (S. aureus); Staphylococcus capitis (S. capitis); Streptococcus oralis (S. oralis); and Streptococcus koreensis (S. koreensis). Oral health conditions may have affected the contamination of the inner layer. In addition, the number of times the mask was touched may have affected the contamination of the outer layer.

“…Since the use of rotary instruments has proven to be faster, obtaining well-filled canals and uniform results with respect to manual instrumentation, the need arises to assess which rotary instruments are more effective in primary dentition, achieving a better three-dimensional preparation, cleaning and obturation of the canals [ 25 ]. Although there is the possibility of using alternative therapies such as light-activated disinfection for cleaning temporary root canals, which would be widely accepted by children and parents, this study will focus on the analysis of the different current rotary systems [ 26 ].…”

The need to perform fast, effective and efficient pulpectomies has led to the development of numerous valid rotary systems. Its technical features allow the clinician to obtain good results in less working time. The objective of this study is to compare the characteristics of the different current rotary systems to favor a correct diagnosis and subsequent treatment. A systematic review of the literature has been carried out in accordance with the PRISMA recommendations. A search was carried out in PubMed, Embase Scopus, Cochrane and Web of Science databases, and was completed with a manual search. The following variables were extracted from the selected studies: author, year, sample, rotary systems used (length, diameter, taper, speed), obturation material and irrigant. From the initial electronic search of the five databases, 315 articles were identified. Once the duplicate articles were eliminated, a total of 233 remained. After reading both title and abstract, 200 articles were eliminated, leaving 33. On account of reading the full text, 22 were eliminated for not answering the research question or the inclusion criteria, leaving a total of 11 articles for the systematic review. Rotary systems which are able to adapt to the root anatomy of primary teeth and allow rapid and simple instrumentation, without producing excessive extrusion of debris at the root apex, will be the ones that provide the best results to the pediatric dentist during the performance of pulp treatment in primary teeth. Clinical success will only be achieved through proper prior diagnosis.

“…PAD (diode laser) in combination with NaOCl may be an alternative and a better option for root canal disinfection for endodontic pathogens [24] . Also, light-activated disinfection (LAD) can be used as a substitute or adjunct to conventional antimicrobial treatment regimens that are implemented to combat polymicrobial biofilms [25] . Within the methods of disinfection of the root canal system, the main irrigant is sodium hypochlorite, together with mechanical shaping of the root canals.…”

Introduction: Streptococcus gordonii is known as an opportunistic pathogen that can cause local or systemic diseases, such as apical periodontitis and infective endocarditis. Objective: To evaluate Streptococcus gordonii in relation to its prevalence, treatment, diagnostic methods, as well as its endodontic and systemic role. Methodology: A search for information was carried out in databases such as PubM ed, SCOPUS and Google Scholar, using logical operators AND, OR and NOT. We searched for the mention of Streptococcus gordonii bacteria related to the keywords: prevalence, treatment, identification methods, role in endodontics and systemic disease. Results: It is found in teeth with abscesses in 11.1% and in canals with apical periodontitis in 55%. In methods of treatment of the canal system we found that the main irrigant is sodium hypochlorite, lasers and photodynamic therapy. In diagnostic methods we found matrix-assisted laser desorption ionization, Next-Generation Sequencing analysis and PCR. In the cell wall of S. gordonii they act as virulence factors, forming biofilms that can cause apical periodontitis, endocarditis and pneumonia. Conclusion: This microorganism easily adheres to host tissues, forming biofilms that can cause apical periodontitis, endocarditis and pneumonia. It is of utmost importance to raise awareness of its role in order to select the best treatment.
