Abstract

Background: Despite the large number of trials conducted using herbal oral care products for the reduction of dental plaque or gingivitis, results are conflicting and inconclusive.

Objective: To assess the effectiveness of herbal oral care products compared to conventional products in reducing dental plaque and gingivitis adults.

Methods: We searched the following databases for Randomised controlled trials (RCTs): MEDLINE Ovid, EMBASE Ovid etc. which yielded 493 trails. Of which 24 RCTs comparing herbal toothpaste or mouth rinse with over the counter toothpaste or mouth rinse in adults aged 18 to 65 years were included. Two authors extracted information and assessed the methodological quality of the included studies using Risk of Bias. Meta-analyses using the random-effects model were conducted for four outcomes for tooth paste and mouth rinse respectively. Mean difference (MD) or standardized mean difference (SMD) were used to estimate the effect, with 95% confidence intervals.

Results: A total of 1597 adults participated in 24 RCT studies. These were classified as herbal toothpaste (HTP) (15 trials, 899 participants) and herbal mouth rinse (HMR) (9 trials, 698 participants) compared with non-herbal toothpaste (NHTP) or non-herbal mouth rinse (NHMR). We found that HTP was superior over NHTP (SMD 1.95, 95% CI (0.97-2.93)) in plaque reduction. The long-term use of NHMR was superior in reduction of dental plaque over HMR (SMD -2.61, 95% (CI 4.42-0.80)). From subgroup analysis it showed that HTP was not superior over fluoride toothpaste (SMD 0.99, 95% CI (0.14-2.13)) in reducing dental plaque. However, HTP was favoured over non-fluoride toothpaste (SMD 4.64, 95% CI (2.23-7.05)).

Conclusion: For short-term reduction in dental plaque, current evidence suggests that HTP is as effective as compared to NHTP; however, evidence is from low quality studies.

Background

To systematically review the effectiveness primary molar pulpotomy based on the clinical and radiographic outcomes using lasers over the conventional therapies.

Material and Methods

This systematic review and meta-analysis included Randomized or Quasi-randomized trials comparing LASER with conventional pulpotomy therapies (formocresol, ferric sulphate, MTA or calcium hydroxide) with atleast 6-month follow-up period was included. Risk of bias of included studies was assessed and metanalysis was done using RevMan software.

Results

Of the 1383 articles that were searched, only 14 studies were included for qualitative synthesis and 10 for meta- analysis. There was no statistically significant difference in clinical success rate [OR 0.99, 95%CI (0.19,5.22)] or radiographic success rate [OR 0.77, 95%CI (0.31,1.87)] of LASER therapy compared to Formocresol in primary molar pulpotomy for 6 months. No statistically significant difference were found in clinical success rate [OR 1.04, 95%CI (0.35,3.07)] and radiographic success rate [OR 0.71, 95%CI (0.37,1.35)] at 12 month follow-up also. Comparison of LASER with Ferric Sulphate also did not show a statistically significant difference.

Conclusions

Meta-analysis showed no statistically significant difference in clinical and radiographic outcomes of LASER pulpotomy with conventional pulpotomy (formocresol and ferric sulphate) at 6 and 12 months follow-up. However, there was considerable risk of bias in the included studies.

Dr. R. Venkitachalam, K, K., J, J., V, R., and C, J., “Oral health care system analysis: A case study from India”, Journal Family Medicine and Primary Care, 2020.[Abstract]


Objectives:

The health system of Kerala, India has won many accolades in having health indicators comparable to developed countries. But oral health has not received its due importance at the policy level. With the burden of oral diseases on the rise in the state, a critical introspection of the existing system is warranted. The objective of this review was to assess the oral health care system in Kerala to provide policy solutions.

Methods:

This study adopted a mixed methodological approach that gathered information from the primary and secondary sources, which included health facility surveys, key informant interviews, review of published literature, and websites of governmental and non-governmental bodies. The WHO framework of health system building blocks was adapted for the assessment.

Results:

A review of epidemiological studies conducted in Kerala suggests that the prevalence of oral diseases is high with the prevalence of dental caries at the age of 12 years ranging from 37-69%. The state has a dentist population ratio of 1:2200 which is well within the prescribed ratio by WHO (1:7500). Only 2% of dentists in Kerala work with government sector catering to 0.6 million of the approximately 33.4 million population. This point to the absence of oral care in first contact levels like primary health centers. Service delivery is chiefly through the private sector and payment for dental care is predominantly through out-of-pocket expenditure.

Conclusion:

Despite having the best health indicators, the oral health system of Kerala is deficient in many aspects. Reorientation of oral health services is required to combat the burden of diseases.

Background: To compare the anti plaque efficacy of Modified Bass, Fones and Normal brushing techniques in young adults.

Material and Methods: An investigator blinded randomized controlled trial with parallel design was adopted to compare the anti plaque efficacy of three tooth brushing techniques. The study population consisted of 120 dental students aged between 18 and 30 years.

Results: At the baseline, the mean plaque scores were 0.74 ± 0.39, 0.77 ± 0.34 and 0.98 ± 0.36 respectively, for Modified Bass, Fones and Normal brushing technique. After 24 hours without any oral hygiene activity, the plaque scores increased to 1.04 ± 0.30, 1.11 ± 0.32 and 1.21 ± 0.40, respectively. After 1 week of using the intervention, the mean plaque scores were 0.78 ± 0.36, 0.94 ± 0.34 and 1.03 ± 0.43, respectively and increased to 1.13 ± 0.44, 1.14 ± 0.40 and 1.08 ± 0.34 after 28 days. The mean gingival scores were 0.23 ± 0.66, 0.02 ± 0.52 and 0.42 ± 0.74 for Modified Bass, Fones and Normal Brushing technique during baseline visit and after 28 days.

Conclusions: There was a significant reduction in the amount of plaque with the three brushing techniques. Although the short-term outcomes with the Modified Bass method were promising, a long-term effect was not evident. Further, there was no significant difference in plaque control between the three groups. Gingival scores, plaque scores, tooth brushing techniques, young adults.

Abstract Objective Shade matching is a critical procedure in prosthetic dentistry. The correct identification of the shade by the doctor as well as the perception of the shade by the dental technician becomes critical due to the high patient expectations. The current study aims to evaluate the effect of gender and clinical experience on shade perception by dental professionals. Materials and Methods A total of 100 dental professionals with normal color vision who were categorized as dental students, dental doctors, and dental specialists were included in the study. Masked A2 and B2 shades tabs were made to match with a complete set of shade guide. The obtained data were entered, coded, and analyzed using SPSS version 17 for Windows. Results Total number of participants who identified both shade tabs correctly was 44%. There were no statistically significant differences among the gender or the clinical experience with regard to correct identification of shade tabs. Conclusion Within its limitations of fewer number (two) of shade tabs for comparison, the study concludes that multiple opinions may be taken clinically irrespective of the gender or clinical experience as gender and experience do not have a significant role to play for shade matching in prosthetic and restorative dentistry.

Vol. 17, 2019.[Abstract]


To tackle the combined burden of oral diseases and other noncommunicable diseases (NCDs), a comprehensive and integrated approach by focusing on common modifiable risk factors and social determinants is of importance. Experts from the field of dental public health and public health deliberated on finding common grounds for linking oral health and NCDs during theFirst Amrita International Public Health Conference 2018, Kochi. A symposium on oral health - a public health problem, panel discussion on NCD and oral health and a key note lecture on Universal Oral Health Coverage were conducted as a part of the conference. The following are the highlights of the scientific deliberations held during the conference.

Continuing surveillance of levels and patterns of various oral diseases is required for planning and evaluating community-based health promotion. Unfortunately, India has only a single nation-wide oral health survey to date. Therefore, integration of oral health with NCDs prevention program will be successful only if surveillance of oral disease is also concurrently done.[1] Persistent and consequential oral health inequities exist...

The year 2018-19 brings a lot of hope with the improvement of health-care services across the globe and particularly in India. The World Health Organization's (WHO) Health Day's theme for this year is 'Universal Health Coverage' (UHC)[1] which put in simple terms is ensuring that everyone, everywhere, can access essential quality health services without facing financial hardship. This concept of UHC is based on the constitution of the WHO (1948) which considers health as a fundamental human right and on the Alma Ata declaration with the agenda of Health for All.[2] Worldover, there has been a call for UHC to ensure not only health but also social and economic development.

Introduction: Non-Communicable Diseases (NCDs) have assumed epidemic proportions around the world. Oral diseases also pose tremendous physical and emotional burden on the people. Both these conditions (NCDs and oral diseases), are largely caused by a cluster of risk factors like tobacco, unhealthy diet, physical inactivity and harmful use of alcohol (to name a few!). Aim: The objective of the study was to assess the common risk factors between Non- Communicable diseases (cardiovascular diseases, pulmonary diseases, diabetes mellitus type 2 and stroke); and oral diseases. Materials and Methods: A cross-sectional study was conducted with a sample of 280 patients in four NCDs groups like cardiovascular diseases, pulmonary diseases, diabetes mellitus type 2 and stroke. The risk factors for each of NCDs disease were assessed by their medical records, interview of the Physician and patients. In the same patients, oral disease risk factors were assessed and enumerated by clinical examination and a validated clinical questionnaire. Descriptive statistics were used with the demographic data. Cohen’s Kappa was used to assess the degree of agreement for the risk factor to be common to both the NCDs and oral diseases. Results: History of smoking was the most common risk factor between dental caries and diabetes mellitus type 2 (agreement of 15%).Cardiac valve abnormalities were a common risk factor between dental caries and stroke with a 31% degree of agreement. Diabetes as a common risk factor between dental caries and MI had a degree of agreement of 44%.Asthma and oral diseases (dental caries and periodontal diseases) had obesity, history of smoking and positive family history as common risk factors. Conclusion: Smoking is the most common risk factor across the oral diseases and all the six NCDs included in the study followed by family history, obesity, hypercholesterolemia, high blood pressure, diabetes and excessive alcoholism. Thus, oral disease prevention programs can be integrated with the NCD prevention programs.

Introduction: Health promoting school (HPS) is a holistic concept where health and learning coexist. The objective of this study was to assess the health promoting standards of schools in Kerala.

Methodology: A cross-sectional study was designed in Kerala, India, with schools in Kerala as a study unit. A questionnaire which consisted of 37 items across eight domains of the HPS concept was developed and validated. The schools were then graded into compliant and not compliant categories based on scores obtained. Bivariate and multivariate analysis was also done.

Results: Of 120 schools, 90.8% were compliant toward health education domain and only 8.3% were compliant with nutrition services. Majority of schools showed compliance with the other six domains. Average overall scores were 153 (58.8%) with the equal number of schools in both compliant and not compliant categories. There was a significant association between health education and physical education domain with respect to the type of school, i.e., privately managed had six times more chances of being compliant toward health education domain compared to government schools (odds ratio [OR] 6.05; 95% confidence interval [CI] 1.10-33.29). Hence, also private schools had two times more chance of being compliant toward physical education compared to government schools (OR 2.52; 95% CI 1.0 - 4.32). Physical education domain showed a significant association with respect to geographic region, i.e., the schools in North Kerala were found to be three times more compliant compared to South Kerala (OR 3.48; 95% CI 1.05-11.53).

Conclusions: Despite the good health and social indicators in Kerala, there is a deficiency in schools promoting health of children. A coordinated effort by the government and the education system can convert existing schools into health promoting.

Background: The medical prescription is a valid and legal document. Prescriptions can also be used as a measure of the quality of medical education, observance of the laws and regulations, and sociocultural beliefs.

Aims: To assess the quality of prescription written by dental and medical students and practitioners.

Settings and Design: A cross-sectional study was conducted in three dental and two medical colleges in Kerala covering 345 participants (dental - 235 and medical - 110).

Materials and Methods: Simulation exercise was conducted for drafting a model prescription based on a given clinical condition. The variables were identified based on the model prescription format by the Medical Council of India and were classified into four domains. Points were assigned for each variable.

Statistical Analysis Used: Analysis was performed using descriptive statistics and Mann-Whitney U-test.

Results and Conclusion: The total scores were found to be higher among dental fraternity (10.93 ± 2.88) to medical (10.81 ± 2.55). The medical house surgeons and postgraduates fared better in the doctor identification domain. Among the dental professionals, there was a significant difference among the undergraduates (mean score = 1.91) and postgraduates (mean score = 1.60) in the doctor identification domain. However, among the medical professionals, in the patient identification domain, house surgeons had a significantly higher score compared to postgraduates. There were no significant differences in quality of prescription writing among medical and dental professionals.

Introduction: Dental caries is widely prevalent globally but the distribution and severity of dental caries varies across countries and regions. In the absence of surveillance or real time monitoring of dental caries in India, there exist a need to assess the prevalence in the country for planning and implementation of oral health programs. Aim: To assess the combined prevalence and mean DMFT of dental caries in India among the WHO index age groups (5, 12, 15, 35-44 and 65-74 years). Materials and Methods: Epidemiological/point prevalence studies conducted (among index age groups) in various parts of India from January 2000 to April 2016 were retrieved from Pubmed central database using ‘Dental caries’ AND ‘India’ as MeSH terms and information from the only National Oral Health Survey and Fluoride Mapping (2002-2003) in India were used. The combined mean deft/DMFT and pooled prevalence of the dental caries was assessed region wise for each age group. Results: The mean deft/DMFT was 2.36, 1.95, 3.31 and 7.01 among 5, 12, 15 and 65-74 years respectively. The SiC index shows steady increase from 3.36 to 8.11 across the groups. The mean prevalence of dental caries is almost similar at 5 years and 12 years at 49% while it shows steady increase from 15 years (60%) to 35-44 years (78%) and peaks at 65-74 year group (84%). In the Eastern and Western regions of India, the 15 year old had higher caries prevalence and mean DMFT compared to the 12-year-old. Across India, the 60-74-year-old had the highest DMFT of 7.01. In North and South India, 65-74-year-old had the highest caries prevalence of 84% and 85% respectively. Conclusion: Irrespective of age groups, the prevalence of dental caries was found to be high and varied across India. This data could help health policy makers to tailor region specific oral health interventions. © 2018, Journal of Clinical and Diagnostic Research. All rights reserved.

Oral health is a critical but overlooked component of overall health and well-being. Although there have been impressive advances in both dental technology and in our scientific understanding of oral diseases, significant disparities in both the prevalence of dental disease and access to dental care among population subgroups remain. This paper attempts to elaborate on the nature of oral health equity in India by exploring the process and trajectories of oral health inequity.

Background: Kerala has a large number of tribal communities where the prevalence of tobacco related oral mucosal lesions is alarmingly high. This coupled with ignorance regarding harmful effects of tobacco use is an emerging public health problem. Purpose: To find out dependency of tobacco use in an indigenous population of Wayanad, India.
Methods: A cross- sectional study was designed in the tribal colonies of Kalpetta, Kerala. A multi-stage cluster sampling design was adopted to select the indigenous people living in colonies. A structured close-ended interview was conducted using a 27-item questionnaire, modified and adapted from the National Institute for Mental Health and Neurosciences, India (NIMHANS). The questionnaire consisted of five domains. To assess the dependency of tobacco habit, Fagerstrom Nicotine Dependency Scale for both smoking and smokeless forms of tobacco were used.
Results: Of the 103 responses obtained, 41.7% were males. Participants were in the age group of 14-70 years with a mean age of 43 years. Almost half of the respondents cleaned their teeth twice daily. About 53% of people cleaned their teeth using fingers. Toothpowder and rice husks were the commonly used materials for cleaning teeth (64%) followed by toothpaste (35.9%). It was observed that the prevalence of tobacco use in this population was 73.8%. Majority of the respondents (92%) used smokeless forms of tobacco. The mean scores of nicotine dependency for smoked tobacco was 3.85 (± 2.7) and that for smokeless form was 4.61 (± 2.17). Both these scores denote moderate dependency of tobacco use. The average age of onset of tobacco use was 16.41 years for smoked and 17.53 years for smokeless forms.
Conclusions: The prevalence of tobacco consumption was found to be high among both males and females in the tribal population. Majority of them consumed different forms of smokeless tobacco

Objectives: To assess the existence, structure, and functioning of Institutional Ethics Committees (IECs) in dental teaching institutions in Kerala. Methodology: A cross-sectional questionnaire-based survey was conducted by personally approaching Heads of Institutions/Ethics Committee (EC) in-charge of all dental colleges (23) in Kerala. The validated questionnaire consisted of two parts. The first part pertained to details of institutions, and the second part assessed the structure and functioning of the IEC. The data obtained was tabulated and analyzed using descriptive statistics. Results: Of the participating 17 colleges, 13 colleges had a functioning IEC. Only four of these IECs were accredited to a central agency. Only one among the 12 colleges completely adhered to recommended structure. Regarding the functioning of IECs, 69% of the IECs had neither a separate application form for ethical review of proposals nor a proforma for its evaluation. On average, more than ten proposals were reviewed in a single EC meeting in 54% of the colleges. Nearly 40% of the IECs had no representation of a lay person. Conclusion: The absence of IEC in four colleges and non-accreditation to a central agency was a matter of concern. Enforced accreditation is the need of the hour to ensure ethical protection to human participants. © 2016 Taylor & Francis.
