Oral health status and indicators in children of Armenia based on the national surveys.

BACKGROUND: The aim of this study was to determine the dynamics and the structure of dental morbidity of the children population of the Republic of Armenia, in order to improve the system of methods of therapeutic and preventive measures. METHODS: In recommended children's key age groups, 5879 WHO assessment forms (1997) were analyzed. Calculated prevalence and intensity of dental caries, the Significant Index of Caries (SiC) and European dental health indicators, and the condition of periodontal tissues were determined with the help of the community periodontal index (CPI) and oral hygiene by OHI-S. The statistical analysis was performed within the SPSS 19 (SPSS Inc., Chicago, IL, USA). The obtained data were statistically processed in the STATISTICA 6.0 (StataCorp LLC, College Station, TX, USA) for Excel program (Microsoft Corp., Redmond, WA, USA). RESULTS: The prevalence of caries of temporary teeth was 91.7% on the average. In 12-year-old schoolchildren the average prevalence of caries of permanent teeth rate was 87.5%. The prevalence of periodontal lesions in children was 47.8% on the average. CONCLUSIONS: In Armenia there was an increase in dental morbidity during the 2009-2019 period, which presumably would be continued unless the factors affecting the development of diseases will be changed. To improve dental health at the population level not only specialists but also health authorities should make efforts introducing appropriate prevention programs.

Neurosensory alterations and Interleukins Cascade in SARS-CoV-2 Infection - Results from a Retrospective Cohort of COVID-19 Inpatients.

OBJECTIVE AND DESIGN: The aim of this study was to relate IL-6 and IL-1ß serum levels with the severity of olfactory disorders and with the type of unperceived odors. MATERIALS AND METHODS: 82 inpatients (45 men aged 62.3 ±14.2 and 37 women aged 57.1± 12.8) with only smell dysfunctions were divided into two groups. The evaluation of the smell disorder was carried out with a questionnaire to define which sensitivity is most compromised in COVID-19 patients. Cytokine levels were measured with chemiluminescence and ELISA assay. Statistical analyses were performed with the Wilcoxon Rank test, Welch's Welch's T-test, and Mann-Whitney test (p <0.05). RESULTS: Statistically significant differences in IL-6 and IL-1 ß levels were found in moderate disease patients when there was an impairment of trigeminal sensitivity (p <0.05) and trigeminal and olfactory sensitivity. CONCLUSIONS: The results obtained showed that in COVID-19 patients the impairment of trigeminal sensitivity in association with olfactory sensitivity was more prevalent in moderate than in mild forms.

Evaluation of qualitative and quantitative taste alterations in COVID-19.

A large percentage of coronavirus disease 2019 (COVID-19) patients have taste dysfunction. Interleukin 6 (IL-6) levels in mild and moderate COVID-19 patients with the type (quantitative or qualitative) of taste disorders were compared in this observational study. The 208 COVID-19 patients (118 men and 90 women) revealing only taste dysfunctions as prodromic symptoms were classified as mild and moderate patients. Survey results were used to evaluate the taste disorder. The IL-6 levels were measured using a chemiluminescence assay. Statistical analysis was conducted using the Wilcoxon rank, Welch's, and Mann-Whitney tests. The findings revealed that neither the presence of dysgeusia or phantogeusia nor the perception of sour and salty, differed statistically significantly between moderate and mild patients (P > 0.05). But between moderate and mild patients, there were statistically significant differences in how umami, bitter, sweet, and parageusia were perceived (P < 0.05). There was an impairment of multiple tastes up to ageusia in patients with high IL-6 levels. The findings demonstrated that parageusia and dysfunctions in umami, bitter, and sweet taste perception can be indicators of more severe forms of COVID-19.

Challenges in providing special care dentistry during COVID-19 pandemic: a survey of public dental care services in Italy.

BACKGROUND: The aim of this paper was to assess COVID-19 pandemic impact over the public health care services (HCS) involved in special care dentistry (SCD). METHODS: Customized questionnaire was sent to 45 HCS involved in SCD. Healthcare personnel (HP) on duty, safety of HCS, time of suspension and reduction of routine dental practice in special needs patients (SNP), kind of SNP mostly penalized during pre-COVID period/T1, lockdown (phase 1/T2) and post pandemic reopening (phase 2/T3) were analyzed by statistical means (P<0.05). RESULTS: 21 questionnaires were returned. A significant decrease of median number of HP during T2 was observed. Prevalence of COVID-19 infection among HP was not significantly different between T2 vs. T3. Medical surveillance of HP during T2 was significantly lower than during T3. Patients with lack of cooperation were the most disadvantaged during both phases dental procedures were significantly lower between T1 and T2 and between T1 and T3 as well. Patients with lack of cooperation and/or living in residential care homes were the most disadvantaged in relation to access to dental care during both phases. CONCLUSIONS: COVID-19 pandemic determined significant restrictions in daily access to routine oral care resulting in reduction of preventive evaluations and decline of oral health in a population which is already at a higher risk of oral pathologies. Our data reveal that reduction of dental procedures, healthcare professionals and days of suspension of clinical activity were still considerable also in T3 with respect to T1 and in some cases not significantly different from T2.

Relationship between oral lesions and severe SARS-CoV-2 infection in intensive care unit patients.

OBJECTIVE: Oral lesions received increased attention as likely new signs or secondary manifestations of COVID-19. Therefore, we clinically examined oral cavity of patients with COVID-19 and investigated oral lesions and patient comorbidities as possible risk factors of COVID-19 disease outcome. METHODS: From January to March 2022, a prospective study was conducted by recruiting all COVID-19 patients admitted to the Intensive Care Unit and Respiratory Intensive Care Unit of Maxi-Emergencies Hospital in Bari, Italy. RESULTS: From the enrolled 103 COVID-19 patients, 46.6% were females and 53.4% were males. Findings show that risk of presenting with severe COVID-19 disease was higher in patients who developed oral lesions related to COVID-19 than those with no oral lesions (RR = 7.998, p = .002). Next, patients with concomitant autoimmune diseases were at higher risk of a negative COVID-19 disease outcome than those without comorbidities (OR = 8.838, p = .026). CONCLUSIONS: COVID-19-related lesions of oral mucosa should not be ignored as they can be early and easily detectable signs of severe COVID-19 disease condition, thus, serving as a prevention measure for any potential unfortunate event. Findings of this study, without implying causation, offer a direction for future investigations that aim to confirm the presence of specific oral lesions in COVID-19 patients as signs of severe disease progression.

Application of the Extracts of Uncaria tomentosa in Endodontics and Oral Medicine: Scoping Review.

BACKGROUND: The main purpose of endodontic treatment is to eliminate the bacteria that are responsible for the contamination and infection of the internal surfaces in order to resolve any pulp or periapical pathology. In fact, some bacteria, such as Enterococcus faecalis, can escape the action of root canal irrigants by aggregating into a biofilm and penetrating deeply into the dentinal tubules. Uncaria tomentosa is a plant belonging to the Rubiaceae family and also commonly known as cat's claw due to the shape and position of the spines; it is a traditional Peruvian medicinal plant of Amazonian origin. Applications in the dental field have been described both in the prevention and treatment of stomatitis and as an antibacterial and anti-inflammatory agent; it has also been investigated as an additive in irrigants and specifically as gels in endodontic cements. The aim of this scoping review is to summarize all the scientific evidence on the possible applications of Uncaria tomentosa extracts in endodontics and, more generally, in oral medicine, in order to understand whether the active ingredients extracted from Uncaria tomentosa can bring a real advantage in endodontics, in the reduction of endodontic failures and in the onset of recurrent endodontic lesions. METHODS: The scoping review was carried out strictly following the PRISMA-ScR checklist; the search was carried out on five databases (PubMed, Scopus, Science Direct, EBSCO and Web of Science) and a register (Cochrane library). RESULTS: The research produced a number of bibliographic sources totaling 2104. With the removal of duplicates, 670 were obtained; potentially eligible articles amounted to 23, of which only seven in vitro studies (four microbiological studies), five clinical studies (three randomized trials) and a case report were included. CONCLUSIONS: From the data in the literature, it can be stated that the active ingredients present in Uncaria tomentosa could represent an interesting product to be used in the endodontic field, both in endocanalary cements and as a gel.

Education during the COVID-19 pandemic: the perception of Italian dental and medical students.

BACKGROUND: During COVID-19 pandemic many dental and medical students continued their education from home. From several studies it emerges that students prefer face-to-face teaching, due to the better interaction with teachers, the least number of distractions and due to the negative effect of social isolation on the psychological aspect. The aim of this study was to evaluate the perception of Italian dentistry and medicine students about teaching and training in this scenario. METHODS: Two online questionnaires were sent to medical and dental students of all Italian universities to investigate the limits and advantages of distance learning and the experience regarding the internship. A chi-square test was used to assess the association between gender, year of the course and region of residence (P<0.05). RESULTS: One thousand one hundred thirty-eight students answered the first survey, and 292 the second one. Most students preferred face-to-face teaching due to the difficult to maintain attention during online lessons. Many students reported that the online internship was not adequate for their education. CONCLUSIONS: Distance learning disadvantages are the greater number of sources of distraction, low level of interaction, and absence of the relationship with the patient during the practical training. Furthermore, isolation has strongly affected psychosocial balance of the students. The advantages are the greater comfort, the reduction of transport costs, the decrease in pollution, and the possibility of reviewing the lessons. Most Italian students considered appropriate to provide distance learning during the pandemic but believed that the best teaching method was teaching in presence.

SARS-CoV-2 Infection and Taste Alteration: An Overview.

Since the worldwide spread of SARS-CoV-2 infection, the management of COVID-19 has been a challenge for healthcare professionals. Although the respiratory system has primarily been affected with symptoms ranging from mild pneumonia to acute respiratory distress syndrome, other organs or systems have also been targets of the virus. The mouth represents an important route of entry for SARS-CoV-2. Cells in the oral epithelium, taste buds, and minor and major salivary glands express cellular entry factors for the virus, such as ACE2, TMPRSS2 and Furin. This leads to symptoms such as deterioration of taste, salivary dysfunction, mucosal ulcers, before systemic manifestation of the disease. In this review we report and discuss the prevalence and socio-demographics of taste disturbances in COVID-19 patients, analysing the current international data. Importantly, we also take stock of the various hypothesized pathogenetic mechanisms and their impact on the reported symptoms. The literature indicated that COVID-19 patients frequently present with gustatory dysfunction, whose prevalence varies by country, age and sex. Furthermore, this dysfunction also has a variable duration in relation to the severity of the disease. The pathogenetic action is intricately linked to viral action which can be expressed in several ways. However, in many cases these are only hypotheses that need further confirmation.

COVID-19: The Patients' Perceived Impact on Dental Care.

OBJECTIVES: The present study aims to investigate the effect of the COVID-19 pandemic on people's mental and physical balance, oral hygiene habits, type of diet, perceived safety of returning to the dentist, and aesthetics with the use of masks. MATERIALS AND METHODS: An online questionnaire was submitted to the Italian population between December 2020 and January 2021. It was sent via online platforms and included 21 questions. STATISTICAL ANALYSIS: Differences in rates were calculated by using the Chi-square test. The level of significance was set at p <0.05. RESULTS: A total of 1,008 individuals completed the questionnaire. About 72% of participants were not concerned about returning to the dentist. Approximately 45% of the individuals intensified their oral hygiene and preventive rules. About 38% of participants increased their carbohydrate intake, while 28% increased their fat consumption. Furthermore, 75% of the participants felt that the mask did not diminish the beauty of their smile. CONCLUSIONS: Most participants felt comfortable returning to the dentist but only for more urgent treatment. However, most people reported that they had not stepped up their home oral hygiene measures. The biggest changes in the population's eating habits involved increased carbohydrate and fat consumption. Finally, most participants responded that mask use did not compromise their aesthetics.
