ABSTRACT
PURPOSE: Phenomenology is a branch of philosophy that focuses on human lived experience. Illness including dental diseases can affect this living experience. Within the dental literature, there is very little reported on the use of phenomenology compared to other healthcare sciences. Hence, the aim was to review the literature and provide an overview of various applications of phenomenology in dental research. METHODS: This study was a narrative review using literature in the last 10 years identified by web-based search on PubMed and Scopus using keywords. A total of 33 articles that were closely related to the field and application in dentistry were included. The methodology, main results, and future research recommendations, if applicable, were extracted and reviewed. RESULTS: The authors in this study had identified several areas such as orofacial pain and pain control research, dental anxiety, dental education, oral healthcare perceptions and access, living with dental diseases and dental treatment experience in which the phenomenological method was used to gain an in-depth understanding of the topic. CONCLUSIONS: There are several advantages of using the phenomenological research method, such as the small sample size needed, the diverse and unique perspective that can be obtained and the ability to improve current understanding, especially from the first-person perspective.

Objective: The primary goal was to assess the knowledge, attitude and practice among otorhinolaryngologists regarding orthodontic intervention for Paediatric Obstructive Sleep Apnoea (POSA). Methods: An online survey was conducted by sending an email invitation to members of The Association of Otorhinolaryngologists of Karnataka, India. A total of 141 otorhinolaryngologists participated in the survey. Results: Most of the participants (70.2%) agreed that orthodontic interventions help in opening up the airway, but very few knew about its application in nasal obstruction management. Conclusion: Otorhinolaryngologists are aware of dental effects of POSA and they believe that an interprofessional team is essential for its management. This learning can also be used to initiate interprofessional collaborations and academic and curricular improvisations for enhanced health outcomes.
ABSTRACT
Context: Disturbances in sleep affects the overall quality of a child's life, with several short- and long-lasting consequences. Hence, early diagnosis and monitoring is crucial in the management of sleep disorders in children. Aims: The aim of this study was to evaluate salivary C-reactive protein (CRP) levels in a group of children with Class II malocclusion and sleep problems before and after twin-block appliance therapy. Settings and Design: The study was a prospective clinical study with a 9-month follow-up period. Subjects and Methods: Eleven children aged 8-12 years with skeletal Class II malocclusion and at least one sleep disorder were enrolled in the study. All children were subjected to a recording of their sleep history and a clinical as well as radiographic examination. Pretreatment levels of salivary CRP were recorded. A twin-block appliance was custom made and delivered to every child. At the end of 9-month follow-up, all children were recalled for a re-evaluation of salivary biomarker levels. Statistical Analysis: Pretreatment and posttreatment changes in biomarker levels were assessed statistically using the students paired t-test. Results: Levels of salivary biomarker CRP were significantly decreased in children following myofunctional therapy using a twin-block appliance (P < 0.001). There was a considerable improvement in the clinical symptoms such as a decrease in snoring and noisy breathing in most children post-twin-block therapy. Conclusion: The measurement of salivary biomarker CRP could be used as an alternative and noninvasive method to evaluate prognosis of oral myofunctional therapy for children with sleep disordered breathing.

The main objective of the present study was to evaluate the effect of the morphology of titanium dioxide nanofillers on the flexural strength and shear bond strength of the dental composite. Spherical and rhombic-shaped nano titanium dioxide fillers were synthesized via solvothermal method and were characterized. Subsequently, these fillers were incorporated into a flowable composite (Filtek™ Z350 XT Flowable Restorative) at 0.5 wt.% and 1.5 wt.% and the prepared specimens were stored in water for 24 h. The specimens were then evaluated for flexural strength using a universal testing machine. Similarly, the shear bond strength of modified composites to the tooth was evaluated and bond failures were analyzed using stereomicroscope magnification. Incorporation of nanofillers significantly enhanced the flexural strength of flowable composite (p = 0.009) with a significant increase at 0.5wt.% of spherical (p = 0.015) and rhomboidal-shaped fillers (p = 0.010). However, no statistically significant difference in flexural strength was observed among the different shapes of nanofillers. The results of our study did not show a significant effect on the shear bond strength of the composites. Thus the reinforcing ability of titanium dioxide nanofillers on dental composite was confirmed in this study, although the effect of using nanofillers with different morphology was not significant.

Background: There are various medical insurance options available in India. However, unlike many other countries, dental insurance plans are rare. The aim of this study was to assess the utilization of various government and private health insurance schemes by patients admitted for dental surgical procedures at a tertiary care hospital in coastal Karnataka, India. Methods: A study was conducted retrospectively to gather data on the socio-demographics, bill details, insurance, and benefits claimed by patients admitted to the Department of Oral and Maxillofacial Surgery at a tertiary care hospital from May 2016 to September 2022. Results: Out of 1750 patients, only 856 (48.9%) patients had availed of insurance, 395 patients (22.6%) utilized government health insurance policies, and 461 patients (26.3%) availed of private health insurance plans. Among Government schemes, primarily Ayushman Bharat-Arogya Karnataka was used by 262 (30.6%) patients, followed by Employees' State Insurance Scheme by 110 (12.9%) patients. Among private schemes, 212 (24.8%) patients used the policies purchased by them, 19 (2.2%) patients' medical expenses were paid by their employers, 105 (12.3%) patients utilized Manipal Arogya Suraksha and 124 (14.5%) patients used Medicare provided by the hospital. Bivariate linear regression confirmed that the total bill amount, out-of-pocket expenditure by the patient, and insurance amount reimbursed to the hospital were significantly associated with the type of insurance (government vs. private). The study noticed a gradual rise in insured patients every year. Conclusion: Greater utilization of health insurance should be encouraged because the cost of dental treatment has always hindered the use of oral health services worldwide. This study highlights that the benefit available to the patients were mainly through general health insurance schemes, not specifically dental health insurance. Insurance schemes covering dental must be promoted more aggressively in the media, highlighting their available benefits, merits, and demerits.

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.

Objectives: The study aimed (1) to assess fluoride concentration of groundwater along the Swarna river basin in Udupi District; (2) to investigate variations in fluoride concentration with respect to rainfall status in Udupi district; and (3) to develop a spatial distribution map for the groundwater fluoride concentration in Udupi district. Materials and Methods: Water samples were procured from 30 different sampling points across three time zones in a year: pre-monsoon, monsoon, and post-monsoon. The samples thus collected were analyzed for fluoride ion concentration using fluoride ion selective electrodes (Orion™). Mean determination readings at each time zone were calculated. Repeated-measures analysis of variance was done to analyze whether there was a difference in the concentration of fluoride over different time zones. Results: The mean (SD) pre-monsoon concentration was 0.25 (± 0.07) ppm, whereas the mean monsoon and post-monsoon concentrations were 0.26 (± 0.09) and 0.57 (± 0.23) ppm, respectively. There was a significant increase in post-monsoon fluoride levels when compared with the pre-monsoon and monsoon levels. Conclusion: The groundwater fluoride concentration in the Swarna river basin was found acceptable for human consumption at all the sampled sites and across all time zones. As the fluoride concentration was found to be lower than the recommended values for dental caries prevention at most of the sampling sites, use of topical fluorides needs to be encouraged.
ABSTRACT
Background: For more than 150 years, dental amalgam (DA) has been popular as a dental restorative material. Many organizations oppose its use due to perceived toxicity and environmental concerns. Hence, this study aimed to explore the continued use of DA from a South Indian dental practitioners' perspective. Methods: This cross-sectional study was conducted among fifty-two private and public dental practitioners of Udupi district in Southern India. A selfadministered questionnaire was distributed, that involved assessment of their preferences, continuation of use and concerns of using DA as a restorative material. The percentage contribution of each variable was calculated. Preferences for continuation of use of silver amalgam based upon the age, experience and mercury toxicity as a risk factor were analyzed using Students-t test and Fisher's Exact Test test. Results: Most dentists were satisfied (87%) with the results of the DA, found minimal failures (96%) and found DA more economical (89%). More than half (54%) of the participants reported that they would not continue the use of DA owing to mercury toxicity and environmental concerns. Dentists with higher age and longer clinical experience preferred continuation of DA. Conclusions: Despite satisfaction with DA for its minimal failure, longevity and affordability, the authors found that most practitioners did not prefer its continued usage. This highlights their concerns over mercury toxicity and soft tissue lesions and accentuates their community social responsibility. There is also an urgent need to educate dentists on mercury hygiene, mercury waste management and disposal.

PURPOSE/OBJECTIVES: To investigate dental students' perceptions and concerns regarding the COVID-19 pandemic, their coping strategies and support resources, and their perceived stress levels. METHODS: A customized 19-item survey and the perceived stress scale (PSS) were applied to undergraduate dental students from the US, Spain, Ireland, Chile, India, and Brazil between April 10 and July 5, 2020. Linear modeling and mediation analysis were used to explore the relationships among demographics, stressors, coping mechanisms, social support, and stress RESULTS: A total of 4475 students responded to the survey. The majority (72.4%) were women, and 52.3% had no COVID-19 training at the time of the survey. The students reported that they had to accommodate to changes in patient care (96.6%) and didactic learning (95.2%) activities, while 88.5% of the respondents indicated at least one of their courses moved online. Transition to online courses went "smoothly with some troubles" for 51.8% of the respondents, and 48.3% perceived the faculty as prepared for the online transition; however, 45.9% reported feeling extremely concerned about the impact of COVID-19 on their education. The average PSS score was 21.9 of 40 (moderate stress). Multivariate models were built for participants with full data (n = 3899). Being male, having completed more dental coursework, and perceiving a smoother transition were associated with lower PSS scores; more concern about academic progress was associated with higher PSS. Faculty support mediated the relationship between a smoothness of transition and concern about academic progress and PSS scores CONCLUSION: Stress caused by the pandemic may be alleviated by smoother transition and good faculty support.

OBJECTIVES: The aim was to assess and compare the prevalence of orthodontic treatment need among various special health care needs (SHCN) schoolchildren and adolescents in Dharwad, India. MATERIALS AND METHODS: This cross-sectional study was carried out among 492 subjects in age group of 12-19 years (mean age 14.02 ± 1.84 standard deviation [SD]) who were examined for occlusal anomalies using dental aesthetic index (DAI). They were classified into five groups as: Visual impairment, speech and hearing disability (SH), physical disability, mentally subnormal and multiple disabilities (MD). Chi-square test was used to compare the orthodontic treatment need among various SHCN groups. One-way ANOVA and ANCOVA were performed to test any significant differences in mean DAI scores among the SHCN groups. RESULTS: None of the children were undergoing or had undergone orthodontic treatment for malocclusion. Mean DAI score was 28.81 ± 11.64 (SD). Orthodontic treatment was indicated in 50.2% of study population who had DAI scores of 26 and above. Mandatory orthodontic treatment (DAI >=36) was required in as high as 29% of MD individuals when compared to only 10% of SH individuals. Significant differences in DAI scores were found between the SHCN groups. CONCLUSIONS: The need for orthodontic treatment among SHCN individuals was found to be high. Yet, absence of any orthodontic treatment for any child points out to the fact that the dental services are highly needed in these individuals.
