Validation of ageism scale for dental students in India: (Ageism Scale for Dental Students- India) - a cross sectional study.

Background: Ageism persists in many different societies as it is innate and subconscious in nature. Negative effects such as loneliness, mistreatment, and occupational discrimination are frequently present due to ageism. The dental students in our study were wary of the possible benefits of expensive dental care because ageism is rife in their field. There is no validated and reliable ageism scale to assess how dental students perceive ageism in India. The current study was carried out to validate the ageism scale for dental students in the Indian context. METHODS: This was a cross sectional analytical study carried out among both males and females in Manipal College of Dental Sciences, Mangalore in which the instrument was 27-item Ageism scale for dental students. Content validity was done by six subject experts. The final version was administered to 213 students/Residents of dental school. The factorability of data was confirmed with KMO = 0.61 and Bartlett's Test of Sphericity resulting in p < 0.001. RESULTS: Final PCA model resulted in 15 items and six components that together accounted for 70.37% of overall variance. The six components had reliability ranging from marginal 0.51 (Component 6) to a high of 0.81 (Component 3). As per the gender differences by component females showed less ageism than men in "non-compliance" (-0.9(-1.66-0.14), p<0.05) and "practitioner perspective" (1.43 (0.84, 2.03), p<0.01). Statistical significance was seen in Barriers/concerns in dental treatment of elderly where residents showed reversed (1.4 (0.41, 2.38), p<0.01). Urban group showed more ageism for component 'time restraint' (-0.79 (-1.57, -0.02), p<0.05. CONCLUSION: Preliminary validation resulted in 15 item scale with six components with acceptable validity of the ageism scale and could be further tested in large samples. This scale will help recognize ageism in Indian context and provide necessary information to make changes in the curriculum as required.

Microplastic content of over-the-counter toothpastes - a systematic review.

Background: Microplastic particles are used as ingredients in personal care products such as face washes, shower gels and toothpastes and form one of the main sources of microplastic pollution, especially in the marine environment. In addition to being a potential pollutant to the environment, the transfer of microplastics to humans can become a severe threat to public health. This systematic review was conceptualized to identify evidence for the presence of and characteristics of microplastics in toothpaste formulations. Methods: The PICOS Criteria was used for including studies for the review. Electronic databases of Scopus, Embase, Springer Link, PubMed, Web of Science and Google Scholar were searched, as well as hand and reference searching of the articles was carried out. The articles were screened using the software application, Covidence® and data was extracted. Results: This systematic review showed that toothpastes from China, Vietnam, Myanmar and the UAE, reported no evidence of microplastics and those from Malaysia, Turkey and India reported the presence of microplastics. The shape of the microplastics present in these toothpastes were found to be granular, irregular with opaque appearance and also in the form of fragments and fibers and the percentage weight in grams ranged from 0.2 to 7.24%. Malaysia releases 0.199 trillion microbeads annually from personal care products into the environment and toothpastes in Turkey release an average of 871 million grams of microplastics annually. Similarly, in India, it has been reported that 1.4 billion grams of microplastic particles are emitted annually from toothpaste. Conclusions: The findings of this systematic review provide evidence that toothpastes, at least in some parts of the world, do contain microplastics and that there is a great risk of increase in the addition of microplastics to the environment by the use of toothpaste.

Effectiveness of Silver Diamine Fluoride for Early Childhood Caries Among Children Aged 24 to 72 Months: Protocol for a Randomized Controlled Trial.

BACKGROUND: Dental caries is a serious public health issue globally. It is one of the most prevalent chronic disease in children worldwide. An important public health concern is the existence of one or more decayed, missing, or filled tooth surfaces in any primary teeth of preschool children. Early childhood caries (ECC) can be halted with the use of silver diamine fluoride (SDF) solution. Previous research has indicated that it may have a preventive impact in the treatment of ECC. It is well known that 38% silver diamine fluoride (SDF) is helpful at preventing dental caries. On the other hand, there is not enough evidence on SDF's ability to prevent caries in primary teeth. To date, no well-planned clinical study has been carried out to investigate SDF's impact on caries protection. OBJECTIVE: The study's objective is to evaluate and compare the efficacy of 12%, 30%, and 38% silver diamine fluoride in preventing ECC in children aged 24 to 72 months in Mangaluru Taluk. METHODS: This is a single-center, randomized, active-controlled, parallel-group pragmatic trial. Children attending preschool in Mangalore Taluk aged 24 to 72 months will be included in the study. There will be three study groups: group 1 will receive 12% SDF semiannually; group 2 will receive 30% SDF semiannually; and group 3 will receive 38% SDF semiannually. After 6 and 12 months, the principal examiner will conduct a clinical examination of the teeth with a visual and tactile assessment. The effectiveness of the various concentrations of SDF will be determined after 12 months. RESULTS: The research was funded in September 2020, and data collection started in September 2022. As of February 2023, 150 participants have enrolled in the study. The project is still underway, and it is expected to be completed in December 2023. CONCLUSIONS: Uncertainty surrounds the efficacy of 38% SDF in preventing ECC. Consensus-Based Clinical Case Reporting (CARE) guidelines recommending the use of SDF for ECC prevention will be modified if the findings are as expected. Additionally, since the findings will be broadly disseminated, more nations will implement the use of SDF, easing the burden of ECC on the entire world. Future research on the treatment and prevention of ECC will benefit from the study results. If SDF is successful in preventing caries in a classroom or community context, it will mark an important turning point for preventive dentistry.

Comparative Evaluation of Salivary Sialic Acid Levels Among Beedi Rollers and Tobacco Users in Mangalore, South India.

INTRODUCTION: According to World Health Organization, the global cancer burden is estimated to have risen to 18.1 million new cases and 9.6 million deaths in 2018. Tobacco use is a leading cause of cancer and of death from cancer. Beedis are the most popular smoking form of tobacco in India. Thirty-four percent of the tobacco produced in India is used for making beedis. The beedi sector is agroforestry-based and the second largest industry in India with approximately 4.4 million full-time beedi workers in India. Toxic constituents present in tobacco are released into the ambient air during the processing of beedis. METHODS: A descriptive cross-sectional study was conducted to assess and compare salivary sialic acid levels among beedi rollers, tobacco smokers, smokeless tobacco users and individuals with no tobacco exposure. The study sample comprised of 140 individuals who were 30 to 60 years old, who attended dental screening and treatment camps in rural and urban areas in Mangalore, conducted by the Department of Public Health Dentistry, Yenepoya Dental College and patients who visited the Department of Oral Medicine and Radiology of Yenepoya Dental College. Saliva was collected by passive drool method into a sterile container. Biochemical analysis of salivary sialic acid was done using the acidic ninhydrin method. Continuous variables are expressed in terms of mean and standard deviation. Categorical variables are expressed in terms of frequencies and percentages. To compare salivary sialic acid levels between the groups ANOVA was used. The Chi-square test was used to compare categorical variables between the groups. RESULTS: A total of 140 participants, 35 beedi rollers, 35 smokers, 35 smokeless tobacco users and 35 individuals with no tobacco exposure participated in the study. Among the 140 participants, 90 participants were males and 50 participants were females. There was a statistically significant difference in the mean salivary sialic acid level between the different groups (p<0.001) with smokeless tobacco users having the highest (10.60 mg/dL) mean salivary sialic acid level. It was found that the mean salivary sialic acid level reduced as the age progressed, even though there was no statistically significant difference. There was a statistically significant difference in the mean salivary sialic acid level between the different groups (p=0.010) with participants with 11 to 20 years of exposure to tobacco having the highest (8.67 mg/dL) mean salivary sialic acid level and participants with no tobacco exposure having least (3.06 mg/dL) mean salivary sialic acid level. CONCLUSION: The salivary sialic acid level was more in beedi rollers than individuals with no tobacco exposure, even though the difference was not statistically significant. The results showed elevated levels of salivary sialic acid in smokeless tobacco users followed by tobacco smokers. This may be an indication that smokeless tobacco use has harmful effects similar to or more than tobacco smoking since salivary sialic acid levels in smokeless tobacco users were higher than those in smokers.

COVID-19 in Smokeless Tobacco Habitués: Increased Susceptibility and Transmission.

As the coronavirus disease (COVID-19) pandemic continues to sweep across the globe, the world is responding by implementing public awareness campaigns, social distancing measures, and other preventive strategies to arrest the spread of this lethal disease. Infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exacts a heavy toll on patients with existing comorbidities. Smokeless tobacco (SLT) consumption is of particular concern in countries in South Asia with high population densities, as it facilitates exposure to SARS-CoV-2 within or between communities by the act of public spitting. Salivary droplets generated in this act are a potential threat because they can transmit this airborne infection. Moreover, large gatherings at tobacco retail outlets, frequent hand-to-mouth contact, and sharing of apparatus by SLT habitués could also aid in increasing the spread of SARS-CoV-2. SLT-induced higher expression of angiotensin-converting enzyme 2 receptors along with the presence of furin in the oral mucosa and dysfunctional immune responses among SLT habitués increase viral dissemination and an individual's susceptibility to COVID-19. Issuing rigorous regulations to restrict the use of various forms of SLT products and the obnoxious act of spitting in public can assist in arresting the spread of COVID-19. Widespread education campaigns enlightening the community regarding the adverse effects of SLT consumption and its relationship with COVID-19, along with providing effective assistance to quit for those who are addicted, would decrease the spread of COVID-19.

Evaluation of Salivary Parameters and Oral Health Status Among Asthmatic and Nonasthmatic Adult Patients Visiting a Tertiary Care Hospital.

INTRODUCTION: Asthma is a chronic inflammatory disorder of the airways characterized by attacks of bronchoconstriction causing shortness of breath, coughing, and rapid breathing. Patients undergoing inhalation therapy are subjected to a higher risk of dental caries due to the reduced saliva secretion, decreased pH value, increased number of cariogenic bacteria caused by inappropriate oral hygiene, and the use of inhaling medicaments with dry powder. METHODS: The descriptive study was carried out among 200 patients aged (18-45 years) visiting Yenepoya Hospital, Mangalore during the period from May 2018 to October 2018 to evaluate salivary parameters and oral health status in asthmatic and nonasthmatic patients. Data were collected using WHO criteria (2013) and samples of unstimulated saliva were collected for evaluation of salivary flow rate, pH, buffering capacity, and calcium. Statistical analysis was done using SPSS version 21.0 software with the level of significance set at p < 0.05.  Results: A decreased mean score of salivary flow rate, pH, and buffering capacity were found in asthmatic patients compared to nonasthmatic patients (p < 0.001). A higher mean decayed, missing, and filled teeth (DMFT) score and an increased dental erosion score were found in asthmatics compared to nonasthmatics (p < 0.05). Asthmatics had higher gingival bleeding score than nonasthmatics. CONCLUSION:  In order to prevent disease progression in the hard dental tissue and oral cavity of asthmatic patients, it is necessary to apply adequate preventive measures and motivate their continuous application in this caries-risk population.

Socioeconomic Correlates and Key Aspects of Tobacco Surveillance Using Global Adult Tobacco Survey Among College Students of Mangaluru, South India.

Introduction Tobacco use in recent times has been identified to be the single biggest cause of morbidity and mortality. The epidemic of tobacco use has increased among young adults, which has changed the equation of the prevalence. The contribution of tobacco use to socioeconomic inequalities in health is increasing in India. Adolescent's tobacco use may play an important role in increasing social inequalities related to smoking and smokeless tobacco use. The objective of this research was to study the association between socioeconomic status and tobacco use among college students of Mangaluru, South India Methods To analyze the association between the socioeconomic status and tobacco use, the study was conducted among 18 to 24-year-old college students (n = 802) in different colleges of Mangaluru, South India. A subset of key questions from the Global Adult Tobacco Survey (GATS) was used. The socioeconomic status of the participants was recorded using Kuppuswamy socioeconomic scale (for India) to categorize them into upper class and lower class. Descriptive statistics were applied to assess the factors related to tobacco use and socioeconomic status using SPSS ver. 24.0. Results Approximately 29.7% males and 70.3% of females completed the interview. Among 802 subjects, 69.9% belonged to the upper class and 30.04% belonged to the lower class. The current smokers who smoked daily 1.7% were from the upper class and 1.7% were from the lower class; no statistically significant difference was observed as well (p = 0.97). Approximately 3.4% from the upper class smoked less than daily and 3.1% from lower class smoked less than daily (NS). Among the upper class, 1.8% used daily and 2% subjects from the lower class used smokeless tobacco. A statistically significant difference was observed with subjects between the upper and lower class in noticing cigarette promotions in various forms during the last 30 days of interview. Conclusion Socioeconomic disparities on tobacco use need to be explored to ensure the initiation of new tobacco control activities and monitor the existing tobacco control policies. The current study finding demonstrates a significant but varied role of socioeconomic status on current and past tobacco use.

Effect of Paneer and Cheese Consumption on Salivary Acidogenicity and Calcium Concentration: A Comparative Study.

PURPOSE: To assess and compare the salivary pH reversal phenomenon and calcium concentration in subjects consuming paneer and cheese after an acidogenic challenge and also to compare the salivary pH measurements using pH strips and a portable pen-type pH meter. MATERIAL AND METHODS: Sixty caries free undergraduate students were randomly selected and divided into two group: 1. paneer; 2. cheese. After determining the resting salivary pH using pH strips and a pen-type pH meter, participants were subjected to an acidogenic challenge (10% sucrose). Following consumption of test foods (10-gram cubes), salivary pH was measured at intervals of 5, 10, 15, 30 and 60 min to record the time taken for the salivary pH to return to baseline. Colorimetric salivary calcium concentration was estimated (Biochemical Analyzer) at baseline and after 60 min of test food consumption. The statistical tests used were Shapiro-Wilk's test for normality, repeated measures ANOVA, and the independent t-test. RESULTS: Test meals reversed the fall in pH after acidogenic challenge starting at 5 min and returning to baseline values after 30 min in both groups (p = 1.000). Colorimetric estimates showed higher salivary calcium concentrations with paneer (p < 0.001). The pen-type pH meter showed superior efficiency in terms of time (p < 0.001) compared to pH strips. CONCLUSION: The salivary pH reversal phenomenon was evident after consumption of both paneer and cheese following the acidogenic challenge. Consumption of paneer significantly increased salivary calcium concentration. The pen-type pH meter proved to be more efficient.

Knowledge, attitude and anxiety pertaining to basic life support and medical emergencies among dental interns in Mangalore City, India.

BACKGROUND: This cross-sectional study aimed to assess the knowledge, attitude and anxiety pertaining to basic life support (BLS) and medical emergencies among interns in dental colleges of Mangalore city, Karnataka, India. METHODS: The study subjects comprised of interns who volunteered from the four dental colleges. The knowledge and attitude of interns were assessed using a 30-item questionnaire prepared based on the Basic Life Support Manual from American Heart Association and the anxiety of interns pertaining to BLS and medical emergencies were assessed using a State-Trait Anxiety Inventory (STAI) Questionnaire. Chi-square test was performed on SPSS 21.0 (IBM Statistics, 2012) to determine statistically significant differences (P<0.05) between assessed knowledge and anxiety. RESULTS: Out of 183 interns, 39.89% had below average knowledge. A total of 123 (67.21%) reported unavailability of professional training. The majority (180, 98.36%) felt the urgent need of training in basic life support procedures. Assessment of stress showed a total of 27.1% participants to be above high-stress level. Comparison of assessed knowledge and stress was found to be insignificant (P=0.983). CONCLUSION: There was an evident lack of knowledge pertaining to the management of medical emergencies among the interns. As oral health care providers moving out to the society, a focus should be placed on the training of dental interns with respect to Basic Life Support procedures.

Effect of Herbal and Fluoride Mouth Rinses on Streptococcus mutans and Dental Caries among 12-15-Year-Old School Children: A Randomized Controlled Trial.

To assess and compare the effect of herbal and fluoride mouth rinses on Streptococcus mutans count and glucan synthesis by Streptococcus mutans and dental caries, a parallel group placebo controlled randomized trial was conducted among 240 schoolchildren (12-15 years old). Participants were randomly divided and allocated into Group I (0.2% fluoride group), Group II (herbal group), and Group III (placebo group). All received 10 ml of respective mouth rinses every fortnight for a period of one year. Intergroup and intragroup comparison were done for Streptococcus mutans count and glucan synthesis by Streptococcus mutans and dental caries. Streptococcus mutans count showed a statistically significant difference between Group I and Group III (p = 0.035) and also between Group II and Group III (p = 0.039). Glucan concentration levels showed a statistically significant difference (p = 0.024) between Group II and Group III at 12th month. Mean DMF scores showed no statistical difference between the three groups (p = 0.139). No difference in the level of significance was seen in the intention-to-treat and per-protocol analysis. The present study showed that both herbal and fluoride mouth rinses, when used fortnightly, were equally effective and could be recommended for use in school-based health education program to control dental caries. Trial registration number is CTRI/2015/08/006070.

Acidogenic Potential of Plain Milk, Milk with Sugar, Milk with Cornflakes and Milk Cornflakes with Sugar: A Comparative Study.

AIM: To compare the acidogenic potential of plain milk, milk with sugar, milk with cornflakes, and milk cornflakes with sugar by assessing the salivary pH. MATERIALS AND METHODS: The study was carried out on 40 school children of 8 to 12 years; 20 boys and 20 girls were randomly selected. The salivary pH was assessed before and after the consumption of milk; milk and sugar; milk and cornflakes; and milk, sugar, and cornflakes. Baseline unstimulated saliva was collected in sterile plastic tube and the pH was recorded. The change in the salivary pH from the respective groups after consuming the test meal was recorded as follows: (1) after 5 minutes; (2) after 10 minutes; (3) after 15 minutes; (4) after 30 minutes; (5) 120 minutes. Statistical analysis was done using Statistical Package for the Social Sciences 18.0 (SPSS). RESULTS: The average baseline salivary pH among all the groups was 7.26. A fall in pH at 5 minutes was seen in all the four groups. However, at different time intervals 5, 10, 15, 30, and 120 minutes, the pH values between the groups showed a significant difference at p < 00.7, 0.005, 0.001, 0.010, and 0.028 respectively. CONCLUSION: The fall in pH in all the groups was not significant to a limit of critical pH. Milk when added with sugar and/or cornflakes as a meal did not pose a threat as there was not significant decrease in pH. HOW TO CITE THIS ARTICLE: Bhat SS, Hegde SK, Bhat VS, Ramya KM, Jodalli PS.

Posturedontics: How does dentistry fit you?

Dentists are at high risk for musculoskeletal disorders (MSD's) due to their work. MSD's is an umbrella term for number of injuries affecting different parts of the body, including joints, muscles, tendons, nerves that can arise from sudden exertion or making the same motions repeatedly. These injuries can develop over time and can lead to long-term disability. Dental professional often develop musculoskeletal problems due to bad working habits, uncomfortable physical posture causing unnecessary musculoskeletal loading, discomfort and fatigue. Ergonomic principles when it is applied, it will help to reduce stress and eliminate many potential injuries and disorders associated with the overuse of muscles, bad posture, and repeated tasks. This can be accomplished by using a proper dental chair, lighting and the selection of ergonomically-friendly equipment to fit the dental professionals physical capabilities and limitations. This review addresses about the basics of ergonomics, positioning, viewing, handling, and prevention of MSD's.

Evaluation of knowledge, experience and perceptions about medical emergencies amongst dental graduates (Interns) of Belgaum City, India.

INTRODUCTION: Medical emergencies can occur frequently in dental setting. Effective management of an emergency situation in the dental office is ultimately the dentist's responsibility. The lack of training and inability to cope with medical emergencies can lead to tragic consequences and sometimes legal action. For this reason, all health professionals including dentists must be well prepared to attend to medical emergencies. Providing basic life support [BLS] is dentist's most important contribution until definitive treatment for a medical emergency can be given. Hence the study is aimed to assess the dental graduates (Interns) knowledge, skills and competency regarding dentistry-medical emergency interface. METHOD: Data were collected from 105 Interns of two dental colleges of Belgaum City using a structured questionnaire consisting of 7 item questionnaire (6 closed and 1 open ended). RESULTS: Overall in all the years, syncope / faint was seen by 40.9% of the respondents, 37.1% with hypoglycemic attacks, allergic reactions by 17.1%, epileptic attacks by 7.6%, asthmatic attacks by 4.5% and angina 0.9%. The frequencies of the emergencies encountered were once or even more. Knowledge of the presence of drugs and equipments in the emergency drug kit and the confidence in regard to use them was low. Medical emergencies training were undertaken by 42% respondents, but in varying degrees. There was a desire for further medical emergencies training by majority of respondents. CONCLUSION: The study showed that syncope is the commonest medical emergency event. Dental graduates had a superficial knowledge of medical emergencies, drugs and equipments. Emphasis is placed on the need for more medical emergencies training to be offered, to increase knowledge and confidence of dental graduates (Interns) in the management of medical emergencies. Key words:Medical emergencies, dental graduates, basic life support, emergency drugs.
