COVID-19 and Personal Protective Equipment-Related Challenges Faced by Pediatric Dentists during patient care: A Qualitative Study

Abstract Objective: To describe the challenges pediatric dentists face while caring for their patients during the pandemic. Material and Methods: A descriptive qualitative study was conducted with purposefully sampled pediatric dentists. Data were collected through in-depth, semi-structured interviews until the content of the collected data reached theoretical saturation. Data were transcribed verbatim, coded, and analyzed using content analyses. Results: Seven participants (four females and three males) between 29 and 50 years participated in the study. Three themes emerged from the analyses: Anxiety and fear; PPE (Personal Protective Equipment) and its impact on care delivery; and 3) Behavior management. Conclusion: Dental care delivery was challenging for pediatric dentists. They experienced high anxiety levels and modified their services according to the recommended guidelines while making accommodations to lessen patients' COVID-19-related anxiety. The additional mandated PPE use affected the communication between the dentists and their patients, affecting their dentist-patient bonding.

COVID-19 Related Knowledge, Attitude, Practice Evaluation among Indian Dental Patients: A Cross-Sectional Survey

ABSTRACT Objective: To assess the awareness about COVID-19 among dental patients and determine the association between COVID-19 awareness and perceived stress among dental patients. Material and Methods: A selfadministered knowledge, attitude and practices (KAP) questionnaire and perceived stress scale (PSS) were employed to assess the knowledge and attitude among dental patients visiting the outpatient department. A p-value of ≤ 0.05 was considered statistically significant. An independent t-test was used to compare the KAP and PSS scores based on age, gender, occupation and the responses to unscorable questions. Spearman's correlation was employed to assess the association between KAP and PSS scores. Results: The older participants (mean KAP score = 16±2.2), the participants who answered that the Coronavirus outbreak changed their daily routine (mean KAP score = 15.8±2.2) and the participants who answered that they changed their plans due to the Coronavirus outbreak (mean KAP score = 16±2.14) had significantly higher KAP scores when compared to their respective counterparts. The Spearman's correlation value of -0.45 suggested a moderate negative association between the KAP and PSS scores, but this correlation was not statistically significant. Conclusion: The participants had a moderate to good level of knowledge related to COVID-19 and were positive in their approach and outlook on overcoming the pandemic.

Impact of Internet Addiction on Academic Performance of Undergraduate Dental Students of Bhubaneswar, India

ABSTRACT Objective: To assess the level of internet addiction and its impact on the academic performance of undergraduate dental students of Bhubaneswar. Material and Methods: A cross-sectional descriptive survey was steered among 814 undergraduate dental students (representing first year through internship) in Bhubaneswar, India. Internet addiction was assessed with the Internet Addiction Test (IAT) developed by Young, which consisted of 20 items rated on a 5-point Likert scale. Google Forms were used to collect the data. Statistical tests like Chi-square, Kruskal-Wallis, and Spearman correlation coefficient were used to analyze the qualitative and quantitative variables, respectively, with the significance level set at p ≤ 0.05. Results: The prevalence of Internet Addiction was found to be 27.5%. Interns showed the highest mean Internet Addiction (57.91±10.71) score. The proportion of addicted students was higher in males, 74 (31.4%), than in females, 150 (26%). The mean scores for individual domains were overuse (16.31±3.64), non-restraints (7.77±2.66), inhibiting the flow of life (9.52±3.05), emotional state (11.25±2.86), and dependence (10.47±2.53). A correlation coefficient (Spearman's rho value of -.167) indicates a negative correlation between internet addiction and academic scores, which was statistically significant (p=0.001). Conclusion: This study revealed that internet use for varying purposes eventually leads to addiction and affects students' academic performance. The affected students need early intervention and control over internet usage.

Evaluation of Lung Volume and Effect of Vital Staining as Motivation to Quit Tobacco among Nicotine Dependents of Kanpur, India

Abstract Objective: To quantify and compare respiratory functions and further screen the oral mucosa of tobacco and non-tobacco users. Material and Methods: First control group, non-tobacco users (n=55); Second group, smokers' group (n=168) who currently smoked cigarettes; Third group smokeless/chewing type, tobacco group (n=81); Fourth group, both smokeless and smoking type tobacco users (n=46). Fagerstrom Test for Nicotine Dependences (FTND) and Fagerström Test for Nicotine Dependence-Smokeless Tobacco (FTND-ST) instruments were used to assess nicotine dependence. Subsequently, spirometry and Toluidine Blue (TB) vital staining were performed. Chi-squared and one-way analysis of variance (ANOVA) were used for statistical analysis. Results: Fagerstrom test resulted in 48.8% of subjects with low dependency, followed by an increase in nicotine dependency from low to moderate (29.2%), moderate (15.6%), and highly dependent (6.4%) groups. All respiratory function tests and oral screening confirmed significant changes amongst tobacco and non-tobacco users. The forced vital capacity of non-smoker group was significantly different from other tobacco users' group (p<0.05). Conclusion: Early effects of tobacco use can lead to complications with the respiratory system and oral cavity. Such data can be used to delineate the harm of tobacco and should be used to urge individuals to evade the utilization of tobacco (AU).

Comparison of Oncostatin M in Patients with Chronic Periodontitis with and without Diabetes

Abstract Objective: To compare the Oncostatin M (OSM) concentrations in tissues of patients with chronic periodontitis with and without diabetes. Material and Methods: Sixty-four subjects visiting the dental outpatient department were categorized as "healthy" (Group 1), "periodontitis" (Group 2), and "diabetes with periodontitis" (Group 3) groups. The clinical oral examination included assessment of plaque, gingivitis, probing depth, clinical attachment level. Blood glucose was assessed for group 3 patients. OSM concentration in the tissues was assessed using ELISA in all groups. Results: The mean OSM was 0.02 ± 0.04 pg/mg in the healthy group, 0.12 ± 0.09 pg/mg in the chronic periodontitis group and 0.13 ± 0.10 pg/mg in the diabetes-periodontitis group. A significantly higher mean OSM was seen in Group 2 and Group 3 than Group 1. The amount of OSM positively correlated with probing depth and clinical attachment level. Conclusion: Periodontal disease causes a rise in Oncostatin M, independent of the diabetic status. Expression of OSM in the gingival tissues can serve as an inflammatory marker.

Sources of Oral Health Information and its Relationship on Knowledge Among Indian Adolescents

ABSTRACT Objective: To assess the current level of oral health knowledge and identify information sources among adolescents in Bhubaneswar, India. Material and Methods: A cross-sectional examination was conducted among 1330 adolescents aged 13 to 15 years enrolled in 24 randomly selected government and private schools in Bhubaneswar. A specially designed self-administered questionnaire was used to collect the responses. Chi-square test with a level of significance set at 5% was used for statistical analysis. Results: Parents (55%) followed by media (18%) were the major sources of oral health information among the study population, which was statistically not significant in relation to gender and school type. Many subjects (95.3%) perceived sweets could cause tooth decay; however, this was statistically significant only among school type (p<0.05). Around (45%) knew about fluoride and only 36% properly identified fluoride's action as preventing cavities. This was statistically significant among both gender and school type (p<0.05). Seventy-five percent of students effectively distinguished gum disease symptoms, which was significant only with gender (p<0.05). Around 55% identified that oral habits have an influence on oral health, which showed significance among gender (p<0.05). Conclusion: Children oral health knowledge was not satisfactory, highlighting the need to utilize parents, schoolteachers and media to provide oral health education. It's essential for designing and implementing a person-centered care model in dentistry.

ABSTRACT Objective: To assess the usefulness of online teaching for undergraduate students during this Corona pandemic, to point the drawbacks of online teaching, and to learn the areas of improvement in online teaching for the future. Material and Methods: A descriptive cross-sectional study on 130 students was done in Bhubaneswar, Odisha, India. The questionnaire consisted of two parts, personal details and specific information. The first part of the questionnaire consisted of questions related to age, gender, etc. The second part had questions pertaining to online teaching. Pearson's Chi-square test was applied and the level of significance was set at 5%. Results: Most of the students (83.3%) were in the view that classroom lectures are the best mean of imparting knowledge, which was significant (p<0.001). A significant number of students (88.1%) agreed that online teaching is the best method of teaching apart from classroom teaching. Almost all the students (93%) agreed significantly that online teaching is the best way to learn in this present pandemic scenario. Most students (59.6%) agreed that connectivity/network issue is a major drawback in online teaching, which is again significant (p<0.001). Conclusion: Here in these testing times, the role of online teaching becomes important for medical/dental students, both undergraduates and postgraduates, to keep up with their studies.

Effect of Oral and Maxillofacial Injuries on the Development of Post-Traumatic Stress Disorder: A Cross-Sectional Study

ABSTRACT Objective: To assess the influence of oral and maxillofacial trauma on the development of Post-Traumatic Stress Disorder (PTSD) and to determine the efficiency of the Impact of Event Scale-Revised (IES-R) as a diagnostic tool for detecting PTSD in patients with Oral and Maxillofacial injuries. Material and Methods: PTSD was assessed one month postoperatively by the diagnostic instrument, IES-R, to arrive at a provisional diagnosis. A structured clinician-administered PTSD Scale then assessed the patients for the Diagnostic and Statistical Manual of Mental Disorders-5th edition (CAPS-5) to establish a final diagnosis. The assessment of the severity of PTSD was done based on various types of oral and maxillofacial injuries. Results: The IES-R scale provisionally diagnosed 54 subjects with PTSD, out of which 42 were diagnosed to have PTSD by the CAPS-5 scale. Subjects with injuries involving the 'orbital complex,' those presenting with a perceptible scar in the maxillofacial region and with multiple avulsed/ luxated anterior teeth, showed a higher affinity to develop PTSD, and this was statistically significant. Conclusion: Higher levels of PTSD in patients with injuries to the maxillofacial region warrants correct diagnosis and detection, and hence the maxillofacial surgeon plays a vital role in this regard. The IES-R is a useful diagnostic tool to detect PTSD early.

Age Estimation by Modified Demirjian's Method in a Hospital-Based Population: A Radiographic Study

ABSTRACT Objective: To test the modified Demirjian's method of dental age estimation on the South Indian population and correlate it with the patient's chronological age. Material and Methods: This retrospective radiographic study was performed on digital panoramic radiographs taken during a one-year duration. Radiographs of patients in the age range from 8 to 18 years were included in the study. The radiographs were examined and according to the stage of the crown and root status of the left side mandibular teeth. The stage of calcification was observed for eight teeth in the mandibular arch and was recorded in a specially designed proforma. Each rated tooth with stage was converted into a score using a conversion table specified for girls and boys. Results: 224 digital panoramic radiographs were retrieved from the radiologic database. Out of total study sample, 49.5% (n=111) were boys and 50.5% (n=113). The mean chronological and estimated dental age using dental maturity scores resulted in an overestimation of 3 years and eight months. Also, it was noted that there was a strong positive association between chronological (real) and dental age. Conclusion: It was observed that there was a strong correlation between chronological and dental age. A new formula for determining the chronological age from the estimated dental age was derived. Further studies on a larger population may prove the reliability of this age estimation method.

Radiographic Assessment of Third Molars Agenesis Patterns in Young Adults

ABSTRACT Objective: To determine the prevalence of third molar agenesis and associated characteristics. Material and Methods: A total of 2374 panoramic radiographs were retrieved from the radiological archives and evaluated in a computer monitor under optimum viewing conditions. The basic demographic data (age and sex) and the primary findings regarding the presence or absence of third molars in the maxillary and mandibular arches were recorded systematically in a specially designed proforma. Categorical variables were compared using the Chi-square test. Results: A total of 2000 panoramic radiographs were included in the study, of which 1004 were females (50.2%), and 996 were of males (49.8%). The incidence of third molar agenesis was 486 patients (24.3%). Maxillary third molar showed a higher prevalence of agenesis (28.8%) than mandibular third molars (16.4%). A total of 1514 patients (75.7%) had third molars in all four quadrants, and the remaining 486 patients (24.3%) had agenesis of third molar tooth in at least one of the quadrants. Single tooth agenesis was observed in 219 (11%) patients, two teeth agenesis in 172 (8.6%) patients, three teeth agenesis in 39 (2%) patients, and four teeth agenesis in 56 (2.8%) patients. Conclusion: The present study exhibited a maximum number of single tooth agenesis. It was also observed that maxillary third molar agenesis is more than the mandibular third molar and the right side is more than the left side. Agenesis of the third molar is more prevalent in males as compared to females.

Is Mucormycosis an inevitable complication of Covid-19 in India?

ABSTRACT Mucormycosis or black fungus infection is a less common disease but highly fatal infection, infecting the immunocompromised individuals. The site of predilection of the fungus is found to be lungs and brain in addition to its sequestration in sinusoidal spaces. Presently with the ongoing COVID 19 pandemic, the prevalence of this infection is found to be high in the Indian population. The fungus establishes itself by affecting the compromised immune system of an individual and thereby making the individual susceptible to other diseases/ infection. The reasons attributed to the sudden upsurge are steroidal therapeutics abuse, tocilizumab therapy and diabetes mellitus.To avert the cytokine storm, the medical health workers are necessitated to include steroid drugs in COVID 19 treatment protocol however inclusion of these drugs in patients who do essentially require steroids can have their immune system debilitated and permit the invasion of this fungus. According to International Diabetes Federation (IDF), 77 million Indians are known to be diabetic, cautioning the physicians to be vigilante of the impending black fungus infection in the event of COVID19 affliction in such individuals. There is causal relationship between anti-hyperglycemic drugs and weakened immune system and opportunity for the fungus invasion. This review attempts to explain the inter-relatedness of COVID19 infection, its treatment and eventual black fungus infection risk.

Assessment on Oral Health Knowledge, Attitude, and Behaviour and its Association with Sociodemographic and Habitual Factors of South Indian Population

ABSTRACT Objective: To assess the oral health knowledge, attitude, behaviour, and its association with sociodemographic and habitual factors among South Indian Population. Material and Methods: A total of 288 adults living in a residential community situated in Chennai were selected by systematic random sampling method participated in this cross-sectional study. Data collection was carried out using a validated questionnaire. Results: About 97.9% of the participants in our study had good knowledge, 33.3% had a positive attitude and 48.2% had adequate oral health behaviour. Sociodemographic and habitual factors like diet (p=0.006), education (p=0.009), and employment (p=0.003) were significantly associated with knowledge. On the other hand, diet (p=0.012) was the only factor significantly associated with attitude. Ownership of house (p= 0.030) was significantly associated with behaviour and no factor was associated with all three KAB profiles. Absence of correlation were identified between Knowledge-Attitude (r=0.11, p=0.23), Knowledge-Behaviour (r= -0.037, p= 0.68) and Attitude-Behaviour (r =0.01, p=0.94). Conclusion: It has been found a massive number of participants possessed a high knowledge level towards oral health. On the other hand, less than half of the participants had a positive attitude and adequate behaviour towards oral health. No positive linear correlation was seen among knowledge, attitude, and behaviour towards oral health.

Effectiveness of Transcutaneous Electrical Nerve Stimulation Therapy on whole Salivary Flow in Patients with Xerostomia and Healthy Adults

ABSTRACT Objective: To evaluate and compare the effectiveness of transcutaneous electrical nerve stimulation (TENS) therapy on whole salivary flow in patients with xerostomia and healthy adults. Material and Methods: Thirty subjects with a history of xerostomia and subjects withunstimulated salivary flow equal to or less than 0.5 ml in 5 min were included in the study group, and 30 healthy subjects were included in the control group. Low forced spitting unstimulated saliva was collected for five minutes in a test tube fitted with a funnel. Then electrode pads of the TENS unit were applied bilaterally on skin overlying the parotid glands and at optimal intensity, stimulated saliva was collected for 5 minutes with the same method in a separate graduated test tube. The salivary flow rate (per minute) was calculated by dividing the amount of collected saliva (volume in mL) by the duration of collection period (5 minutes) and the salivary flow rates prior and after electrostimulation were compared for both groups. The Student's t-test (unpaired and paired) was performed for group-wise comparisons. Results: In study group, the mean unstimulated salivary flow rate was 0.07 ± 0.01 mL/min. There was an 85.71% increase in salivary flow (0.13 ± 0.03 mL/min) during the TENS application and the difference was highly significant (p<0.001). In control group, the mean unstimulated salivary flow rate was 0.37 ± 0.07 mL/min. There was a 21.62% increase in salivary flow (0.45 ± 0.07 mL/min) during the TENS application and the difference was highly significant (p<0.001). An increase in mean salivary flow rate both in males and females after TENS application in both groups (p<0.001) was noted. The difference between unstimulated, stimulated and mean difference in salivary flow rate between males and females was notstatistically significant in both groups (p<0.05). Conclusion: TENS can be an effective therapy in increasing whole salivary flow rates in patients with xerostomia.

Comparative Evaluation of Surface Roughness of Resin- Modified Glass Ionomer and Glass Hybrid Restorative Materials Simulated by Tooth Brushing: An in-Vitro Study

ABSTRACT Objective: Tocompare the effect of tooth brushing on surface roughness of Resin-Modified Glass Ionomer Cement (RMGIC; GC Gold label 2LC Light Cured Universal Restorative) and Glass Hybrid (GH; GC EQUIA SYSTEM- EQUIA Forte™ Fil and EQUIA Forte™ Coat) restorative material at 1- and 3-months interval simulated by tooth brushing. Material and Methods: RMGIC and GH material specimens (20 each) were prepared according to manufacturer instructions in 10mm × 2 mm dimensions using a mylar strip. A specially designed toothbrush simulator was used along with Oral B Pro 2 2000N powered toothbrush and Colgate Total dentifrice (Colgate-Palmolive India limited; Relative dentin abrasivity - RDA:70- Low abrasive) to perform brushing strokes. Specimens were subjected to surface roughness analysis before and after simulated tooth brushing at baseline, 1, and 3 months. Results: The intragroup comparison was done using repeated-measures ANOVA. Intergroup comparisons were done using an independent sample t-test and General Linear Model (ANCOVA). Surface roughness increased from baseline through 3 months in both RMGIC and GH groups. The mean surface roughness in RMGIC group was significantly higher than GH group at baseline 1 and 3-months, respectively (p<0.001, <0.001, and <0.001). Interaction between group and baseline surface roughness was not significant (p=0.466). The estimated marginal means were significantly higher in RMGIC than GH group (p=0.008). Conclusion: The surface roughness of both RMGIC and GH restorative increased from baseline to 1 month and 3 months after the simulated toothbrushing protocol. GH exhibited significantly lower surface roughness than RMGIC at all the tested intervals.

Validation and Assessment of COVID-19 Peritraumatic Distress Index among Indian Dental Professionals

ABSTRACT Objective: To establish the validity of COVID-19 Peritraumatic Distress Index (CPDI) questionnaire and assess the stress with its associated factors during COVID-19 among dental professionals in Bhubaneswar, India. Material and Methods: An online survey through Google Forms was steered among 234 dentists. CPDI questionnaire was used for data collection post its validation assessment. Content validity was judged satisfactory by two psychiatrists, and excellent internal consistency was found (Cronbach's alpha = 0.92). For statistical analysis, chi-square and binomial logistic regression tests were used with a significance level of p=0.05. Results: 70 (29.9%) were males and 164 (70.1%) were females with a mean age of 30.58 ± 6.70 years. Around 50% had an MDS degree and were attached to an institution and nearly 80% were having experience of less than 10 years. The mean CPDI score was found to be 29.09 ± 15.47. A statistically significant association was observed between CPDI scores with age (p<0.003), gender (p<0.03), practice (p<0.06) and education (p<0.006). Binomial logistic regression revealed that odds of stress were 2 times higher among males than females (OR=2.01, p<0.04), which was statistically significant. Conclusion: Acceptable validation scores confirmed CPDI as an effective instrument for detecting stress. Importance of early interventions to combat the issue of stress among dental professionals as it is allied with negative consequences on health and furthermore affects daily activities is highlighted.
