Abstract

 Modes of transmission of the COVID-19 virus are still unclear. The virus could spread through direct routes, including aerosols and saliva, and indirect transmission through contaminated surfaces. Dental practitioners produce airborne infectious particles especially when using rotary instruments during treatment. Oral fluids, blood, and oral mucosa are also sources of infection, so dentists are exposed to coronavirus more than other medical staff. Indeed, designing appropriate protocols and prevention strategies are highly important. In this review paper, we will explain and review the transmission pathways of the coronavirus, clinical signs of infected patients, dental office infection control, and dental treatment considerations.

Abstract

     Background and purpose: Respiratory function of patients is a major part of orthodontic diagnosis and treatment planning. It is affected by the dimensions of the pharyngeal airway. In this study, these dimensions were compared in patients with different skeletal patterns.
Materials and methods: This cross-sectional descriptive-analytical study was performed studying the cephalograms of patients attending the Orthodontic Clinic affiliated with Mazandaran University of Medical Sciences 2016-17. After tracing, 144 cephalograms were divided into three groups: class I, II, and III (n= 48 per group) based on the ANB angle. The nasopharyngeal, oropharyngeal, and hypopharyngeal dimensions were measured. Data were analyzed using SPSS V24.
Results: The highest mean dimensions amongst nasopharyngeal, oropharyngeal, and hypopharyngeal spaces were found in class I (21.25mm), III (10.49mm), and III (15.89mm), respectively. There was no significant difference between class I and II in the nasopharyngeal space (P=0.108). There were significant differences in the mean dimensions of all three spaces studied between class I and III and class II and III (P <0.05).
Conclusion: Airway dimensions seem to vary among different classes of sagittal malocclusion. The dimensions of oropharyngeal and hypopharyngeal airways decrease with increase in ANB angle, but the dimensions of the nasopharyngeal airway are not associated with the changes in ANB angle and are higher in people with class I skeletal occlusion.

Abstract

 
Background and purpose: In many universities, the physical presence of dental students is required to learn the theoretical sciences and clinical skills. These students are at a high risk to get infected with Coronavirus disease 2019 (COVID-19) because aerosol production and close contact with patients is inevitable. In this review study, the challenges in educating dental students during the COVID-19 pandemic and related solutions are discussed.
Materials and methods: MEDLINE, Scopus, Ovid, and Google scholar databases were searched for relevant articles published in English until September 7, 2020. Articles with the target population of specialty/general dentistry students were included and studies associated with graduate dentists or other pandemics were excluded. After quality assessment, 49 studies were included in current review.
Results: The COVID-19 pandemic caused disruption in traditional face-to-face dental education which was replaced by synchronous learning. This type of learning is faced with some challenges, including lack of sufficient facilities and lack of familiarity of involved people. In this situation, teaching and assessment of theoretical modules should continue virtually with high quality. Clinical units should also be organized by grouping students in smaller numbers and more shifts while adhering to new infection control protocols. Research can also be continued on animal models and COVID-19-related subjects.
Conclusion: Improving the structure of theoretical and clinical education in dentistry is recommended to deal with similar crises in the future.

Abstract

 Background and purpose: Candidiasis is an opportunistic infection caused by Candida species which occurs following the host´s immunological weakness. Restrictions in treatment of fungal diseases such as drug resistance and side-effects increased interest towards exploring new drugs, especially herbal medicines. The objective of this study was to compare the antifungal effects of methanolic extract of Rhus Coriaria and nystatin on Candida albicans strains.
Materials and methods: In this experimental-in vitro study, the antifungal effect of Sumac methanolic extract on Candida alicens strains was assessed by minimum inhibitory concentration (MIC) test and broth microdilution method. In addition, MIC was performed on these strains using nystatin.
Results: The methanolic extract of Rhus Coriaria did not show the ability to inhibit Candida albicans strains at5 low concentrations.  It exerted its inhibitory effect at least at 512 mg/L, while the effective range of nystatin was 0.016-0.125 mg/L. In addition, results of MIC, MIC50, MIC90, and G mean revealed lower values which indicated the higher inhibitory potency of this drug.
Conclusion: Methanolic extract of sumac exhibited inhibitory effect on Candida albicans at high concentrations and could be used in traditional medicine more broadly against Candida albicans yeast. However, the effect is weaker than that of nystatin.

Abstract

Background and purpose: Removable prostheses made of polymethyl methacrylate are susceptible to Candida-dependent denture stomatitis and Candida albicans is considered to be the first common cause. The aim of the present study was to investigate the antifungal effect of acrylic resin modified by zinc oxide nanoparticles.
Materials and methods: In this laboratory study, 72 disks (10*4 mm) made of polymethyl methacrylate (Acropars, Marlic, Iran) were divided into three groups (n= 24). Concentrations of zinc oxide nanoparticles (ZnO NPs) were 1 (group A), 0.5 (group B), and 0 (group C, control) mg/ml. Samples were studied in laboratory using Candida albicans strains (ATCC 10231) according to CLSI M27-A3 and M27-S4 documents. For data analysis, one-way ANOVA and Scheffe's post-test were performed using SPSS V24.
Results: There were significant differences in mean numbers of fungal colonies in study groups. The amount of fungal colonies in group A was lower than those in group B and in group B was lower than those in group C (P<0.05).
Conclusion: Considering the limitations of this study, findings showed that zinc oxide nanoparticles have antifungal activity, which increases by increase in concentration of nanoparticles.

Abstract

 Obstructive sleep apnea (OSA) is a sleep-related respiratory disorder that has a relatively high prevalence among children and adults. OSA has several anatomical and pathophysiological etiologies and is characterized by recurrent periods of narrowing of the pharynx and airway, increased resistance to airflow, and decreased or interrupted airflow during sleep. This disease has several complications which lead to decreased quality of life. Once diagnosed, orthodontists are able to prescribe various methods to treat the disease. The aim of the present study was to review effective orthodontic treatments and their advantages and disadvantages in treatment of OSA. PubMed, Scopus, Web of Science, and Cochrane Library databases were searched for relevant articles published in English until April 30, 2022. Articles on orthodontic treatments in patients with OSA were included. After assessment of studies, 60 articles were included in current review. Findings showed that treatment with oral appliances is effective in OSA patients. Due to the unwanted dental and skeletal side effects of oral appliances in long-term use, it seems better to have this treatment performed by an orthodontist to regularly monitor the occlusion of the teeth and, if necessary, to change the settings of the appliances. In patients with severe OSA, it is better to evaluate the effectiveness of appliance therapy and, if needed, perform surgical treatments.

Abstract

 Background and purpose: Thyroid gland disorders are the second most common disorders of the endocrine system which can affect oral health and patients' health-related quality of life. The aim of this study was to evaluate the oral health-related quality of life (OHRQOL) in patients with thyroid disorders.
Materials and methods: In this case-control study, 43 patients and 43 healthy people were asked questions about demographic information, systemic conflicts, alcohol consumption, oral dryness, OHRQOL, years of illness, and medication (in case group). Then, patients were clinically evaluated and oral health indicators such as gingival index, plaque index, bleeding from gingival salicylate, and DMFT were assessed on Ramford teeth. Unstimulated salivary samples were taken in both groups and weight measurement was performed. Data analysis was performed in SPSS V24 applying independent T-test and Mann-Whitney U test.
Results: Significant differences were found between the two groups in quality of life related to oral health ADD-OHIP-14 (P=0.015) and unstimulated saliva flow rate, GI, SBI, and DMFT (P<0.05). Among quantitative variables, only DMFT in case group was found to have a significant positive correlation with OHRQOL (r=0.318, P=0.038).
Conclusion: Lower quality of life linked to oral health in patients with thyroid disorders requires more attention and follow-up programs in order to solve their periodontal and dental problems.

Abstract

Background and purpose: Hyperdontia is defined as supernumerary teeth (ST) in deciduous or permanent dentitions which can cause a variety of dental, occlusion, and cosmetic problems. This study aimed to evaluate the prevalence and location of ST in different classes of malocclusion in a population of orthodontic patients attending a private orthodontic clinic in Sari, North of Iran between 2006 and 2021.
Materials and methods: In this cross-sectional study, the records of 4873 patients were reviewed. ST characteristics and malocclusion classes were studied using panoramic radiography, lateral cephalometry, and intraoral photographs. Data analysis was performed in SPSS ver.26 applying Chi-square, Mann-Whitney, Kruskal-Wallis, and Fisher's exact test.
Results: Out of 4873 records, 36 (0.74%) patients had ST. These included 21 (58.3%) women and 15 (41.7%) men with a mean age of 23.39±10.76 years. The prevalence of ST was not significantly associated with sex, classes of malocclusion, and the type of teeth (P= 0.317, 0.02, and 0.18, respectively). However, significant correlations were found between the incidence of ST and the direction (unilateral or bilateral), malocclusion, and type (maxilla or mandible) and direction (left or right) of the jaw (P<0.001).
Conclusion: Distribution of ST is significantly associated with the direction, malocclusion, and left or right jaw. Nevertheless, additional studies are required in order to offer the best treatment.

Abstract

Background and purpose: Plaque-induced gingivitis is the most common form of gingivitis caused by the accumulation of bacterial plaques. Chlorhexidine mouthwash is one of the oldest and most effective treatments for this disease. Considering the adverse effects of chemical mouthwashes and turning to plant extracts, this study compared the anti-inflammatory effects of Lippia citrodora and chlorhexidine mouthwashes in patients with plaque-induced gingivitis.
Materials and methods: In this single-blind randomized clinical trial, 72 patients with plaque-induced generalized chronic gingivitis were randomly divided into three groups of 24 patients receiving Lippia citrodora, chlorhexidine, and placebo mouthwashes. Gingival (GI), plaque (PI), and bleeding on probing (BOP) indexes were measured for the Ramfjord teeth of each patient on days 0, 7, and 21 and inputted to SPSS software (Version 22). Comparisons before and after interventions in each group were performed by paired t-test or its non-parametric equivalent for GI and PI, as well as the McNemar test for BOP. An intergroup comparison was performed by independent t-test, one-way analysis of variance (ANOVA) for GI and PI, and chi-square for BOP. Moreover, a comparison of treatment results between different measurements was carried out by repeated measures ANOVA for GI and PI, as well as the Cochran test for BOP.
Results: During all study periods, GI, PI, and POB significantly decreased in all three groups (P<0.001). The highest and lowest decreases of these indexes occurred in chlorhexidine and placebo groups, respectively (P<0.001).
Conclusion: Lippia citriodora mouthwash is not more effective than chlorhexidine; however, considering their slight difference, it can replace chlorhexidine in the treatment of gingivitis.

Abstract

 Background and purpose: Condensing osteitis is the local reaction of bone to a pulp inflammatory stimulus with low intensity and long duration and is the most common radiopaque pathogen lesion in the jaw. The aim of the present study was to evaluate the frequency of condensing osteitis in apex of teeth with deep caries and restorations in panoramic radiographs.
Materials and methods: This cross-sectional study evaluated panoramic radiographs of 2039 patients attending Sari Dental School clinic for dental treatments during 2018-19. Demographic information, including age and sex were recorded. All panoramic radiographs were taken with Cranex D (soredex, Finland) panoramic device and Ortho CP-G Plus films. Lesions in the area of teeth with extensive restoration or deep caries (condensing osteitis) were examined in both jaws. Data were analyzed in SPSS V21 using Kolmogorov-Smirnov test, Fisher's exact test and Chi-square.
Results: According to findings, 364 panoramic radiographs had condensing osteitis. The frequency of radiopacity at the apex of teeth with condensing osteitis was significantly higher in women than men (P=0.042). But there was no significant association between condensing osteitis and border, shape, jaw type, tooth type, and age (P<0.05).
Conclusion: This study showed a relatively high prevalence of condensing osteitis in our patients in dental clinic at Mazandaran University of Medical Sciences. Current findings support the theory that condensing osteitis lesions may form a reaction associated with severely decayed, restored, or pulpitized teeth.

Abstract

 Background and purpose: This study investigated the relationship between oral health related quality of life and hyposalivation and dry mouth in patients with chronic renal failure (CRF) undergoing hemodialysis.
Materials and methods: This descriptive-analytical study was conducted in 200 patients with CRF undergoing hemodialysis attending the dialysis department in Sari Imam Khomeini Hospital, 2021. Patients completed oral health-related quality of life questionnaires (OHIP-14) with additive and simple count assessment methods. To diagnose dry mouth, unstimulated saliva was collected and patients were asked nine questions, of which five positive answers indicated dry mouth. Data analysis was done in SPSS V18. Pearson's or Spearman's correlation coefficient were applied to investigate the association between quality of life score and unstimulated salivary flow, and t-test or Mann-Whitney test were used to compare the quality of life scores between the groups with and without dry mouth.
Results: Hyposalivation was observed in 66 patients (33%). The OHIP-14 score was significantly higher in both additive and simple count methods in patients with dry mouth and hyposalivation (P<0.05). Comparing different variables, the findings showed that 66.7% of the patients with hyposalivation were older than 58 years of age (P=0.007). In addition, 60.6% of patients with dry mouth had diabetes (P=0.01).
Conclusion: Dry mouth and hyposalivation reduce the quality of life in patients with CRF undergoing hemodialysis. Also, dry mouth and hyposalivation were relatively common problems in these patients. The treatment of these problems is necessary because of their impact on patients' quality of life.

Abstract

Background and purpose: The purpose of this study was to investigate the state of anxiety as one of the indicators for determining the mental health of Sari dental students during the COVID-19 virus epidemic.
Materials and methods: This cross-sectional study was conducted in the year 1400 among all incoming students from 95 to 97, selected by census method, including 143 people in the Faculty of Dentistry of Mazandaran University of Medical Sciences in Sari City. The tools for collecting the required information are a demographic questionnaire and a researcher-made questionnaire on anxiety caused by COVID-19. Based on the score obtained by the participants in this questionnaire, they were divided into three anxiety levels, which included low, medium, and high. Data analysis was done with a chi-square test in SPSS software.
Results: 143 people, including 47 (32.9%) people from the 2016 entry, 55 (38.5%) people from the 2017 entry and 41 (28.7%) people from the 2018 entry participated in this study. 73 (51%) of the participants were women. The results of this study showed that 50.3% of students experience a low level of anxiety, 46.9% experience a moderate level of anxiety, and 2.8% experience a high level of anxiety. Also, a significant relationship between the academic year and the level of anxiety was observed so that the students of the newer year showed a higher level of anxiety. There was no significant relationship between gender and place of residence with anxiety level (P>0.05).
Conclusion: There is a significant relationship between the level of anxiety and the academic year of the students. In this way, the stress level is higher in the newer entries. To reduce the anxiety level of students, there is a need to revise the management of infection control, improve the work environment, and learn how to deal with patients to protect everyone, as well as education and support from academic institutions.

Abstract


Background and purpose: The sudden outbreak of the 2019 coronavirus (COVID-19) in Wuhan, China, has led to a public health crisis. To prevent COVID-19 transmission, dentists and dental students should use personal protective equipment (PPE) and implement cross-contamination prevention methods while performing dental work. Therefore, the purpose of this study is to examine the use of personal protective equipment among dental students at Mazandaran University of Medical Sciences.
Materials and methods: In this cross-sectional study, 143 dental students at Mazandaran University of Medical Sciences were included in 2020 using the census method. Information, including the year of admission to the university, age, and gender, along with items related to the use of protective gowns, masks, gloves, shoe protectors, and eye protection, was collected from the participants. Data were collected using a researcher-made demographic questionnaire consisting of 33 questions related to the use of PPE against COVID-19. Data analysis was performed using the Pearson and Spearman correlation coefficients in SPSS version 24. The significance level was set at P< 0.05.
Results: During this study, 143 dental students, including 67 men (46.9%) and 76 women (53.1%), were studied. The findings showed that there was a statistically significant relationship between age, year of admission, and marital status with the use of PPE (P<0.05). However, no significant relationship was found between the use of PPE and students' gender or place of residence.
Conclusion: According to the findings, the level of compliance with personal protective principles was moderate in more than half of the students. However, it is necessary to provide additional training to students who are in direct contact with these patients to prevent viral diseases, including COVID-19.
