Indian Journal of Dental Research (2024)

Shivashankar Kengadaran Vikraman Rakshagan K P Indumathi Arun Kumar Sundaragopal Vani Anusha Adiraju

Abstract Background: Dental Unit Water Line (DUWL) deliver water to different handpieces in a dental unit. The water in DUWL circulates in a closed system, where it is taken from a container. The quality of dental water is of considerable importance since patients and dental staff are regularly exposed to water and aerosols generated from dental equipment. Output water from DUWLs may be a potential source of infection for both dental health care personnel and patients. Aim: To assess the microbial contamination in the DUWL among dental clinics in Chennai. Materials and Methods: An in vitro study was conducted on 60 water samples from 20 dental clinics in Chennai in December 2019. Water samples were collected from three different sources of the Dental unit according to ADA guidelines. The collected samples were assessed for the presence of Aspergillus, Acinetobacter, Pseudomonas aeruginosa, and Legionella by agar plate method. The data were analysed using SPSS software version 20. Results: Legionella was the most prevalent microorganism with 70% prevalence in a three-way syringe and 50% in scaler and airotor, followed by Pseudomonas aeruginosa and Acinetobacter with 10% prevalence in scaler and airotor and Aspergillus with a prevalence of 10% in the three-way syringe. Conclusion: Most of the dental units were contaminated with Aspergillus, Legionella, Pseudomonas aeruginosa and Acinetobacter which pose a serious threat to the patients as well as the dentists.

Indian Journal of Dental Research (2024)

Divvi Anusha Mohammed Junaid K P Indumathi Seema Ashwin Bhogte Preetha Elizabeth Chaly

Abstract Objectives: This study aimed to predict oral health behaviour (OHB) using the theory of planned behaviour (TPB) and determine its influence on oral health status and oral health-related quality of life (OHRQoL) among subjects attending the outpatient department of a tertiary dental hospital in India. Methods: A pre-validated questionnaire was used among 240 randomly selected study subjects to record their demographic details, attitudes (Att), subjective norms (SN) and perceived behaviour control (PBC) with regard to dietary habits (DH), oral hygiene habits (OH) and dental attendance (DA) behaviours. OHRQoL and oral health status of study participants were recorded using Oral Health Impact Profile-14 (OHIP-14) and World Health Organization (WHO) Oral Health Assessment Form (2013), respectively. Multivariate analysis was performed after the necessary bivariate comparisons. Results: Among demographic characteristics, the Socioeconomic status (SES) of the study subjects highly influenced their DH and OH ( P < 0.05). DA was largely affected by the age of the study subjects ( P < 0.05). While attitude of the study participants greatly affected their DH, PBC largely influenced their OH and DA behaviours ( P < 0.05). The OHRQoL and Decayed Missing Filled Teeth (DMFT) levels were strongly influenced by the participants’ DA behaviours ( P < 0.05). Conclusions: DMFT scores and OHRQoL were highly influenced by DA behaviour besides others. DA instead was influenced by PBC. Hence, there needs to be a conscious shift towards strengthening the skills of the population to promote oral health.

Development and Validation of Vocabulary Oral Health Literacy Scale

International Journal of Social Rehabilitation (2023)

Narmadha Thangarasu Shivashankar Kengadaran Divvi Anusha

Purpose: Literacy is the ability of a person to read and write. Most of the adult population struggle to understand basic information regarding health and oral health due to lack of literacy. There are several tools to assess the oral health literacy of adult population. The main disadvantage with other scales were the pronunciation of the words as it varies in India. Hence a new one named Vocabulary Oral Health Literacy Scale was formulated to overcome this problem. The aim of this study was to develop and Validate Vocabulary Oral Health Literacy Scale with four different domains. Materials and Methods: A cross-sectional study was conducted among 104 subjects belonging to the age group of 16–60 years residing in Puducherry. Approval was obtained from Institutional ethical committee before the start of the study. A simple random sampling was used to select the study subjects. The data was collected using a well-structured proforma. The proforma consisted of two parts. The first part collected demographic data and the second part consisted of 10 common dental words for word recognition, 10 pictures for identification, 10 words with missing letters, and 5 lines for word comprehension. The data were entered in Microsoft excel spreadsheet and analysis was done using IBM Corp. Released 2012. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp. Results: A total of 104 subjects were included of which 41% were male and 58% were female with mean age of 20.95 ± 9.24 and 20.19 ± 5.39, respectively. Reliability tests revealed Cronbach’s alpha value of 0.723 and split half reliability value of 0.815. There was a positive correlation between all the four domains of VOHLS, Word recognition versus picture recognition (0.420); Word recognition versus filling the words (0.421); Word recognition versus comprehension (0.429); picture recognition versus filling the words (0.507); picture recognition versus comprehension (0.211); and comprehension versus filling the words (0.477). Conclusion: The Vocabulary Oral Health Literacy Scale showed a good reliability in the assessment of oral health literacy among the study population. There was a positive correlation between all the domains of the scale which shows good internal consistency in the scale. Hence, this scale can be used on a larger population to assess the oral health Literacy.

A Brief Review on Children\'s Oral Health Related Quality of Life Measures in Dentistry

Journal of Scientific Dentistry (2023)

Senthil Murugappan Shivashankar Kengadaran Divvi Anusha Daniel J. Caplan Shyam Sivasamy

Developing measurements for assessing oral health-related quality of life (OHRQoL) in children presents unique challenges.Oral health is greatly influenced by age, resulting in notable differences in OHRQoL between children and adults.While numerous tools exist for measuring adult OHRQoL, this complexity hinders the creation of suitable measurement instruments tailored to children and adolescents.However, developing instruments specifically for these younger populations enables researchers to pinpoint and explore OHRQoL factors unique to them, such as self-image, social acceptance, and the school environment.This paper aims to provide a concise overview of instruments designed to assess the OHRQoL in children.

Effect of Nano-hydroxyapatite Crystal Incorporated Herbal Dentifrice on Remineralization of Incipient Caries Lesion- A Pilot Study

Journal of Pharmaceutical Research International (2020)

Shivashankar Kengadaran Sri Sakthi Divvi Anusha I. Meignana Arumugham Pradeep Kumar Rathinavelu

Fluoridated dentifrices are considered as an effective method for preventing dental caries. Nano-hydroxyapatite crystals which have remineralizing potential can be combined with herbs with antimicrobial activity and used as a dentifrice without any risks like cytotoxicity and adverse effects. Nano-hydroxyapatite crystals are formulated by wet chemical precipitation method and tested using X-ray diffractometer. An herbal dentifrice is formulated from extract of Salvadora persica to which Nano-hydroxyapatite crystals are added. A 3x3mm wide window has been created in 14 extracted first premolars which are then processed through a pH cycling for 7 days. The depth of the lesion is assessed using a confocal microscope. The difference in mean depth of the lesion between test dentifrice (Herbal dentifrice with Hydroxyapatite) (240.33.± 23.47) and fluoride dentifrice (272.75±29.38) was found to be statistically significant. Herbal dentifrice with Hydroxyapatite group mean depth of the lesion was 763.13+66.18 before and 240.33+23.48 after the remineralization cycle. In the Fluoride dentifrice group the mean depth of the lesion is 763.14±66.18 before and 272.55+29.38 after the pH cycle. Herbal dentifrice incorporated with hydroxyapatite had higher remineralizing potential compared to a fluoride dentifrice.
