Effectiveness of spaced repetition learning using a mobile flashcard application among dental students: A randomized controlled trial

BACKGROUND

Dental education in India predominantly relies on traditional lecture-based learning (LBL), which may hinder student engagement and learning outcomes. To address these limitations, innovative learning methodologies, such as spaced repetition learning (SRL), are imperative. SRL prioritizes active recall and can enhance long-term knowledge retention. This study aims to assess the effectiveness of SRL delivered through a mobile flashcard application, in enhancing knowledge retention among dental undergraduates.

METHODS

This single-blind randomized controlled trial (CTRI/2023/10/059347), conducted in Belagavi, India, involved 90 dental students who were equally distributed into control (LBL) and test (lecture followed by SRL demonstration) groups after randomization. Rigorous expert review ensured the quality of PowerPoint presentation and mobile flashcard contents. Knowledge assessments were conducted at baseline, first, and third months using a validated and reliable questionnaire. A perception survey on learning techniques was administered after the first month. Analysis methods included descriptive analysis, Pearson's chi-square test, independent t-test, and repeated measures ANOVA with Bonferroni's post hoc test.

RESULTS

The pre- and post-intervention knowledge showed no significant differences, but the SRL group exhibited significantly higher retention at both first month (p ≤ 0.001) and third months (p ≤ 0.001) than the LBL group. Repeated measures ANOVA revealed significant pairwise differences in mean knowledge scores in SRL group. Students had significantly favorable perception toward SRL than LBL group.

CONCLUSION

SRL delivered through mobile flashcards significantly enhances knowledge retention compared to LBL among dental students. Positive student perceptions support SRL's integration into dental curricula, with implications for improving knowledge retention among them.

Oral Hygiene Status, Salivary and Microbiological Parameters Among Visually Impaired and Normal-Sighted Children After Specialized Oral Health Education: An Interventional Study

Aim and objectives To assess oral hygiene status and salivary and microbiological parameters among 12 to 15-year-old visually impaired and normal-sighted children before and after oral health education (OHE). Methodology An interventional study was conducted among 25 visually impaired children (Group A) and 25 normal-sighted children (Group B) in the age range of 12 to 15 years. Simple random sampling was used to select the study participants. A questionnaire was designed to record socio-demographic data and the dietary habits of the children on pre-decided days. The oral hygiene practices and the Decayed Missing Filled Teeth (DMFT) index were recorded, and salivary physicochemical parameters for all the selected children were evaluated, followed by saliva collection for microbial analysis. After baseline assessment, the Audio-Tactile Performance technique for Group A and the animated visual performance technique for Group B children were used to impart OHE. Periodic assessments of salivary parameters were conducted at one-month and three-month intervals. Unpaired T test/Mann-Whitney U test, repeated measures analysis of variance (ANOVA)/Friedman test, followed by Bonferroni's post hoc test were carried out to determine the difference between and within groups, respectively. All statistical tests were performed at a significance level of 5%. Results Group A demonstrated a greater change in salivary pH (6.20 ± 0.41 to 6.96 ± 0.20), salivary buffering capacity (5.80 ± 0.82 to 7.20 ± 0.65), and Streptococcus mutans count (9.36 ± 0.41 to 8.7 ± 0.45 x 104 CFU/mL) when compared to Group B. Group B demonstrated a greater Lactobacillus acidophilus count reduction (7.96 ± 0.66 to 7.50 ± 0.64 x 104 CFU/mL) when compared to Group A. Conclusion The appropriate use of specialized OHE holds particular significance in the improvement of oral hygiene status and salivary parameters, along with a reduction in the bacterial count in both visually impaired children and normal-sighted children.

Comparison of the effectiveness of Morus alba and chlorhexidine gels as an adjunct to scaling and root planing on stage II periodontitis - A randomized controlled clinical trial

OBJECTIVES

The present study aimed to assess and compare the effect of Morus alba and chlorhexidine gel as an adjunct to scaling and root planing (SRP) in treating stage II periodontitis.

METHODS

A single-blind, randomized controlled trial was conducted on 180 patients with stage II periodontitis who received full-mouth SRP. They were randomly assigned to receive chlorhexidine digluconate (CHX) gel, Morus alba (MA) and placebo gel for Groups A, B and C, respectively, at the baseline, 15 days and 30 days. Plaque index (PI), Gingival index (GI), periodontal pocket depth (PPD) and quantitative analysis (culture) of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis and Tannerella forsythia were assessed at baseline and 45 days. Analysis of variance was used to compare the significant difference in PI, GI, PPD and microbiological parameters between the three groups after the intervention, followed by post hoc Mann-Whitney U and Tukey's HSD test for clinical and microbiological parameters, respectively.

RESULTS

Intergroup comparison of the PI, GI and microbiological parameters between the MA and CHX groups at the end of 45 days did not show a statistically significant difference (p > 0.05), whereas a statistically significant difference was observed for PPD between MA and CHX groups with the mean difference of 0.18 mm (p = 0.002).

CONCLUSION

Morus alba gel was found to be effective in decreasing PPD. However, there was no difference between Morus alba and chlorhexidine gel as an adjunct to SRP in treating stage II periodontitis.

Remineralising potential of Ocimum basilicum varnish and fluoride varnish on initial enamel caries: An in vitro microscopic study

Background

The focus of caries research has switched to early identification and non-invasive treatment of carious lesions.

Aim

This study aimed to evaluate and compare the remineralising potential of Ocimum (O.) basilicum varnish and fluoride varnish on initial enamel caries.

Method

The authenticated O. basilicum seeds were procured from a repository, and the extract was prepared using the Soxhlet method, which was vortexed with Indian Pharmaceutical (IP)-graded chemicals to obtain varnish. Extracted premolar tooth samples were divided into three groups of 33 each after demineralisation with a pH of 4.5 for 48 hours at 37°C. Each group was subjected to remineralisation twice daily with respective agents for 4 minutes for 30 consecutive days. Each sample was ground-sectioned through an enamel window. The lesion depth was measured using a light microscope (Leica™ DM2500) and ImageJ software. The data were evaluated using analysis of variance (ANOVA) and post hoc analysis.

Results

The mean (± SD) pre-treatment lesion depth across the groups ranged from 242.11 ± 26.144 μm to 352.66 ± 34.531 μm. The highest lesion depth recovery rate of 45.938% was recorded for the fluoride varnish group, followed by 36.015% in the O. basilicum varnish group, which was statistically significant by Tukey's post hoc analysis (p < 0.001). The gingival fibroblast cells were viable by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay.

Conclusion

The O. basilicum varnish demonstrated a homogenous layer of mineral deposition. However, the remineralising efficacy was slightly lesser than that of the fluoride varnish. Hence, the novel O. basilicum-based remineralisation agent appears to have potential as a non-invasive alternative to topical fluorides in the therapy of early caries lesions.

Assessment of potential antimicrobial activity of Ocimum basilicum extract and chlorhexidine against Socransky's complex pathogens of oral cavity: An in vitro study

Background and Objective

Periodontitis is a multifactorial disease initiated by periodontal pathogens and progresses further in destruction of periodontium. Hence, the objective of this study was to test the efficacy of Ocimum basilicum seeds extract on periodontal pathogens.

Materials and Methods

O. basilicum seeds were authenticated from a recognized taxonomist. They were coarsely powdered; ethanol-based extract preparation was done by the Soxhlet method and aqueous-based extract by hot infusion procedure. Extracts so obtained were assessed for minimum inhibitory concentration, minimum bactericidal concentration, zone of inhibition, and time-kill assay of O. basilicum seeds extract on periodontal pathogens, and comparatively evaluated the effectiveness against 0.12% chlorhexidine (CHX) gluconate in triplicates. Kruskal-Wallis Test was employed wherein the statistical significance was set at P ≤ 0.05.

Results

The concentration of O. basilicum ethanolic extract against periodontal pathogens was determined to be 10 mg/ml, whereas 4.7 mg/ml of aqueous extract was proven effective against periodontal pathogens. Similarly, aqueous extract of O. basilicum developed a wider zone against periodontal pathogens compared to ethanol-based O. basilicum extract. Statistically significant difference found in the effectiveness between both extract and CHX.

Conclusion

The antibacterial activity was evident in both the extracts of O. basilicum against anaerobic periodontal pathogens. However, it was more pronounced in aqueous extract, but lower compared to CHX.

AIM

To assess the oral health practices and the prevalence of dental caries, and periodontal disease among transgenders.

METHODS AND RESULTS

The study was conducted on a sample of 180 participants from the transgender community in Belagavi district over a course of two months. A trained and calibrated examiners recorded oral health status according to WHO dentition status and treatment needs (1997) and Community Periodontal Index (CPI) under the supervision of the subject expert. Chi-square test, spearman's rank correlation coefficient test, multiple linear regression and logistic regression were applied. The statistical significance was set at p ≤ .05 for all the tests. The prevalence of dental caries and periodontal disease among transgenders was 72.2% and 92.2%, respectively. A positive linear correlation and a significant relationship was found between the oral hygiene practices/deleterious habits and dental caries among the transgenders. Multiple linear regression model revealed that the prevalence of dental caries and periodontal disease was significantly associated with age and oral hygiene practices.

CONCLUSION

The prevalence of dental caries and periodontal diseases among transgenders was high. These results may be of use to promote oral health promotion and establishing a paradigm for dentists to work toward improving oral health.

Dental curriculum reform in India: Undergraduate students' awareness and perception on the newly proposed choice based credit system

Background

Dental education plays a crucial role in producing competent dental professionals who can cater to the diverse needs of patients. This study aimed to assess the awareness and perception of the newly proposed Choice Based Credit System (CBCS) by the Dental Council of India (DCI) among dental undergraduate students in Belagavi City, India.

Methods

The study adopted a cross-sectional design and was conducted among undergraduates and interns of two dental colleges in Belagavi, India. A pilot study was conducted, which was followed by sample size estimation. A total 480 participants were recruited by simple random sampling technique. The questionnaire used was self-administered and comprising 23 close-ended questions in English, for which the Cronbach's alpha coefficient was found to be 0.85, with an 84% score for face validity and a content validity ratio of 0.78.

Results

The mean awareness and perception scores were highest among interns, while it was lowest among the first years. Majority of the study participants (62.7%) were unaware of this new curriculum whereas almost half (49%) of them found it to be student-friendly. A positive correlation was seen between the perception and awareness scores (r = +0.270, P ≤ 0.001).

Conclusion

The findings of this study reveal that a significant proportion of dental undergraduates lacked awareness regarding the implementation of the new curriculum, however they had a positive outlook towards it. The adoption of this model appears to be a promising initiative towards enhancing the quality of dental education at a national level.

Risk of periodontitis & dental caries among 35 to 44 year old diabetic individuals: A case control study

Background

The World Health Organization (WHO) has recommended the age group of 35-44 years for surveillance of oral health conditions in adults. There is a growing incidence of early onset of Type 2 diabetes mellitus (T2DM) worldwide.

Objective

This study was conducted to find the strength of association between dental caries and periodontitis in patients with T2DM.

Materials and Methods

This was a case-control study conducted among 35-44-year-old patients with T2DM (n = 185) reporting to various hospitals of Belagavi city and controls (n = 185), who met the inclusion criteria. Group matching was done for age and gender. The study participants were interviewed for their sociodemographic details, relevant medical history, oral health behaviors, and dietary behaviors using a self-designed questionnaire. Dental caries and periodontal status were recorded using the WHO criteria, 2013.

Results

The mean decayed missing filled teeth was significantly higher among controls than cases (P = 0.006). A significantly higher number of cases had periodontal pockets (crude odds ratio: 6.6) as compared to controls. Regression analysis showed that loss of attachment was significantly associated with T2DM (adjusted odds ratio: 5.9, 95% confidence interval: 2.81-6.89).

Conclusion

Periodontitis was found to be associated with T2DM. However, no such association was found between dental caries and T2DM.

Antimicrobial Efficacy of Essential Oils and Their Combination Against Microorganisms Associated With Postradiation Therapy in Patients With Head and Neck Cancer: An In Vitro Study

Background Head and neck cancer ranks as the sixth most common cancer globally. Reduced saliva production brought on by postradiation therapy upsets the delicate balance between bacterial load and a weakened immune system. Oral hygiene is commonly neglected in patients who have undergone radiotherapy and they often develop dry mouth, mucositis due to radiation therapy, etc., as side effects. Despite being a part of the current standard, chlorhexidine carries numerous disadvantages such as taste alteration, teeth staining, and dry mouth. An extensive review of the literature demonstrates the antibacterial properties of essential oils (EOs) derived from plant materials, which may be able to prevent the development of such opportunistic microorganisms in the oral cavity. Methodology The cinnamon bark EO and Cajeput EO were procured and checked for their solubility. The final ratio at which the oils were found to be soluble was the 1:1 (w/v) ratio. The minimum inhibitory concentration (MIC) of cinnamon bark oil (Cinnamomum verum) and Cajeput oil (Melaleuca leucadendron) against Staphylococcus aureus, Enterococcus faecalis, and Candida albicans was determined by serial dilution method using Resazurin dye, and the minimum bactericidal concentration (MBC) was done by a spread plating method. The polyherbal mouthwash was subjected to cytotoxicity assay against human gingival fibroblasts. All the experiments were performed in triplicates. Results The overall results showed that cinnamon bark EO had the strongest efficacy against S. aureus (0.33 ± 0.14 mg/mL) and E. faecalis (0.41 ± 0.14 mg/mL), but not against C. albicans (2.85 ± 2.11 mg/mL). Cajeput EO showed the least efficacy against all the groups; whereas the combination of EOs proved to be the most efficacious and showed good antimicrobial activity against these most commonly encountered microorganisms in head and neck cancer postradiotherapy. Conclusions Cinnamon and Cajeput EOs in combination proved to be effective in this in vitro study against the most common microorganisms encountered in patients with head and neck cancer postradiotherapy and are comparable to 0.2% chlorhexidine.

Comparative Evaluation of Abrasiveness among Three Dentifrices: An In Vitro Study

Aim

A lot of herbal and medicated toothpastes having natural and antisensitivity properties are creating niches for themselves in the market. However, toothpaste containing high content of abrasives can be harmful to the teeth. The present in vitro study was conducted to assess the abrasiveness of three commercially available dentifrices on human-extracted anterior teeth on sound and demineralized enamel.

Materials and methods

A total of 42 freshly extracted teeth were mounted on acrylic resin and randomly divided into three groups (group I, Colgate; II, Glister; and III, Dant Kanti). Each group consisted of one test tooth (partially) and one control tooth (completely) covered with nail varnish. The study had two phases. Phase 1-baseline average roughness (Ra) value was assessed with a profilometer of all the samples. Phase 2-further, teeth were immersed in the demineralizing solution for 4 days to allow the formation of an artificial carious lesion. Tooth brushing was performed by a customized automated toothbrushing model on all the teeth for 28 days. Ra value was again evaluated with Profilometer.

Result

Data were analyzed, and a statistically significant result was observed with demineralized teeth in all three groups (p = 0.005). The intragroup comparison showed a significant difference with demineralized teeth of Colgate and Dant Kanti, (p =0.018) and (p =0.027), respectively. However, there was no significant difference in demineralized teeth of glister and sound teeth of all three groups.

Conclusion

Glister was found to be the least abrasive of all three toothpastes, followed by Dant Kanti and Colgate.

Clinical relevance

The particle size of the ingredients used in manufacturing toothpaste can lead to abrasion of the teeth.This, in combination with the hard bristles, can cause more harm to the teeth than good. The current study has compared the abrasive potential of three commercially available kinds of toothpaste. Hence daily use of these commercially available dental products should be used cautiously.

Evaluation of a "Picture Assisted Illustration Reinforcement" (PAIR) System for Oral Hygiene in Children with Autism: A Double-Blind Randomized Controlled Trial

This study evaluated the potential of a novel pre-validated "Picture Assisted Illustration Reinforcement" (PAIR) communication system and conventional verbal techniques for Oral Health Education (OHE) in terms of dentition status, gingival health, oral hygiene status, and practices in 7- to 18-year-old children with Autism Spectrum Disorder (ASD). A double-blind randomized controlled trial was undertaken in a school for children with autism from July to September 2022. A total of 60 children were randomly assigned into two groups: a PAIR group (n = 30) and a Conventional group (n = 30). Cognition and pre-evaluation of all the children were assessed by standardized scaling measures. A pre-validated closed-ended questionnaire was administered to caregivers of both groups. At a 12-week post-intervention, a clinical examination was performed using the World Health Organization (WHO) Oral Health Assessment form 2013, gingival and Oral Hygiene Index Simplified (OHI-S). The gingival scores in the PAIR group (0.35 ± 0.12) exhibited a statistically significant decline in scores as compared to Conventional group (0.83 ± 0.37), p = 0.043. Meanwhile, the oral hygiene scores in the PAIR group and Conventional group were 1.22 ± 0.14 and 1.94 ± 0.15, respectively (p < 0.05). A significant improvement in oral hygiene practices was observed in the PAIR group. Incorporating the PAIR technique resulted in significant progress in child cognitive ability and adaptive behavior, which reduced gingival scores and improved oral hygiene scores, consequently improving oral hygiene practices among children with ASD.

Pediatric Dental Fluorosis and Its Correlation with Dental Caries and Oral-Health-Related Quality of Life: A Descriptive Cross-Sectional Study among Preschool Children Living in Belagavi

AIM

This study aims to assess the prevalence of dental fluorosis and its association with dental caries, oral health behaviors, oral-health-related quality of life and parents' perceptions among preschool children in the 3-5-year-old preschool children living in the Belagavi district of Karnataka, a non-endemic fluorosis region.

METHODS

A descriptive cross-sectional questionnaire-based study was conducted among 1200 individuals of the preschool population from 48 government-sponsored child-care development centers in Belagavi, Karnataka, over a three-month period. They were examined following the Dean's fluorosis index (1942) and dmft (decayed, missed, and filled) scores of the participants were also recorded. Parents' perception of oral health was assessed using the self-administered Early Childhood Oral Health Impact Scale (ECOHIS). SPSS software (version 20) was used for statistical analysis. Chi-square test computed categorical data. One-way ANOVA test was used for multiple group comparisons. p < 0.05 was considered statistically significant.

RESULTS

Of the 1200 children examined, 10 (0.83%) children exhibited dental fluorosis. Of the 10 children having fluorosis, six had fluorosis present on two or more of their primary teeth, and four had fluorosis on four or more teeth. The mean dmft score was 3.01 ± 1.38 to 3.60 ± 1.72 in 3-5-year-old children, respectively, with statistical significance difference (p < 0.001). The mean score of oral health-related quality of life was 10.74 ± 2.06, which was significantly correlated to the child's age and parents' education level (p < 0.05).

CONCLUSION

The study shows a negligible amount of prevalence of dental fluorosis in the non-endemic fluorosis residential district. It also elucidates that children from lower and lower-middle socioeconomic status are more prone to suffer from dental fluorosis as compared to other groups. The mean score of ECOHIS increased proportionally with the caries experience, indicating a significant relationship between the dmft and ECOHIS score. Deciduous dentition fluorosis is often neglected, especially in areas that are not considered endemic for fluorosis and with only optimum fluoride levels in their groundwater, which supports the disease's nature as multi-factorial and shows that a broader perspective is of prime importance to assess, diagnose, and prevent dental fluorosis among the preschoolers, thereby appraising their overall health and hygiene status.

Unleashing the most effective oral health education intervention technique for improving the oral hygiene status and oral health knowledge in visually impaired young individuals: A systematic review and meta-analysis

Appropriate oral health education (OHE) plays a vital role in prevention of oral diseases and would bridge the gap between dentists and visually impaired individuals. Hence, this systematic review was planned with an aim to evaluate effectiveness of various OHE techniques on the oral hygiene status and oral health knowledge of visually impaired young individuals. An electronic search extended to September 30, 2020 was conducted on PubMed, Wiley, ProQuest, ScienceDirect, Cochrane library, EBSCO, and Google Scholar. Two independent reviewers assessed the studies using a two-stage process; data were extracted according to PRISMA statement. Risk of bias assessment of selected studies was executed according to the study designs. Meta-analysis using the random-effects model was conducted for the outcomes for all oral health education techniques using STATASE 16.1 software. Hand and electronic search identified 3829 articles. After screening for titles and duplicates, 37 articles were retrieved, which were screened through abstract and full text. Of the 37 articles, 17 articles were included for qualitative synthesis, and out of that, 13 were for meta-analysis. Ten variations in oral health education (OHE) techniques were used in the included 17 studies to impart oral health education to visually impaired young individuals. Overall, all OHE techniques demonstrated a positive impact on oral hygiene status. The pooled overall cumulative mean difference of the oral hygiene status after imparting education in ATP, Audio, and Braille was 1.33 [1.06, 1.59], 1.76 [1.11, 2.42], and 1.96 [1.40, 2.55], respectively. An appropriate OHE technique boosts confidence in visually impaired young individuals, making the learning process an enjoyable experience. Use of either Braille or the ATP OHE technique was found to be a reliable and useful method to improve oral hygiene of visually impaired young individuals.

Effectiveness of various irrigant activation techniques on the penetration of sodium hypochlorite into lateral canals of mature permanent teeth: A systematic review and meta-analysis

Objective

This review aimed to systematically review the effectiveness of various irrigant activation techniques (IATs) on the penetration of sodium hypochlorite (NaOCl) into the lateral canals of mature permanent teeth.

Methods

Electronic databases including MEDLINE (via PubMed), Scopus, ProQuest, and Cochrane Library were searched to identify laboratory studies evaluating the penetration of NaOCl into lateral canals following the use of apical negative pressure irrigation (ANP), passive ultrasonic irrigation (PUI), sonic irrigation (SI), and/or manual dynamic activation (MDA) techniques. Meta-analysis was performed for individual IATs in comparison with CNI into the lateral canals of both straight and curved root canals. On the basis of the previous literature and parameters, the risk of bias of the selected studies was evaluated with the help of a customized tool.

Results

Of the 983 records screened, 12 studies were selected to include in the systematic review, and 10 studies were selected for the meta-analysis. The total quality assessment across the included studies indicated a high quality (83.3%). Overall, the meta-analysis demonstrated IATs had significant improvement in the penetration of NaOCl into the lateral canals of straight canals (34.3%) over CNI. The subgroup analysis of individual IATs demonstrated PUI (60.9%) to be superior in the penetration into lateral canals of straight canals.

Conclusions

IATs improved the irrigant penetration into lateral canals and therefore their use during routine endodontic practice is recommended. In straight canals, PUI is the most effective IAT followed by ANP, SI, and MDA techniques.

Prevalence of dental caries, oral hygiene status and treatment needs among seafarers and trainee sailors in the state of Goa, India: a descriptive cross-sectional study

BACKGROUND

The fixed regimen and strict dietary habits of seafarers and trainee sailors, make them susceptible to several oral diseases. The aim of the study was to assess prevalence of dental caries, oral hygiene status and treatment needs among seafarers and trainee sailors in the state of Goa.

MATERIALS AND METHODS

This descriptive, cross-sectional study was carried out from January 2023 to March 2023. After a pilot study, convenience sampling technique was employed to recruit 261 participants. The investigators were standardized and calibrated to record World Health Organization Oral Health Assessment Form (1997) and Oral Hygiene Index-Simplified (OHI-S) which were instrumented in the study. Intra-examiner and inter-examiner reliability scores were recorded using kappa statistics (0.81, 0.83) and (0.83, 0.85), respectively. The data was analysed using descriptive analysis, chi-square test, Mann- -Whitney U test and multivariate linear regression analysis at statistical significance (p ≤ 0.05).

RESULTS

The mean ages of seafarers (n = 133) and trainee sailors (n = 128) were 36.41 ± 6.40, and 25.36 ± 7.39, respectively. The prevalence of dental caries among seafarers and trainee sailors was determined to be 59% and 78%, respectively (p = 0.01). The mean OHI-S score of seafarers (1.31 ± 0.68) and trainee sailors (1.53 ± 0.82) was statistically significant (p = 0.015).

CONCLUSIONS

Seafarers and trainee sailors demonstrated high caries prevalence and poor oral hygiene status due to their distinctive lifestyle, representing a vulnerable community in terms of oral health.

Effectiveness of a Visual Interactive Game on Oral Hygiene Knowledge, Practices, and Clinical Parameters among Adolescents: A Randomized Controlled Trial

This study aimed to evaluate the effect of a novel interactive game-based visual performance technique (IGVP) and conventional oral health educational (OHE) talk on plaque control, gingival health, and oral hygiene knowledge and practices in 12−15-year-old schoolchildren. A single-blinded randomized controlled trial was undertaken in a private primary school in Belagavi, Karnataka, India. A total of 100 children aged 12−15 years were randomly assigned to either a conventional OHE talk (control group, n = 50) or the IGVP technique (test group, n = 50), using a computer-generated table of random numbers. A self-designed, pre-validated closed-ended questionnaire was collected from both groups, followed by clinical examination carried out using gingival and plaque index, pre- and post-intervention, at three months follow-up. There was a significant reduction in the mean gingival score and plaque score in the test group after intervention, indicating a 58.7% and 63.4% reduction, when compared to the control group, which had a 2.8% and 0.7% reduction, respectively (p < 0.001). The test group showed a significant increase in the percentage of knowledge gained (22.4%), compared to control group (7.8%). The IGVP technique proved to be more effective than a conventional OHE talk in the reduction of the plaque score, gingival score, and in the improvement of the knowledge of oral hygiene maintenance and its application.

Assessment of oral health status and tobacco-related habits among the employees of North-West Karnataka Road Transport Corporation (NWKRTC), Belagavi City - A Cross-Sectional Study

Introduction: Transport workers have a very haphazard and incongruent schedule which makes it difficult for them to follow proper oral hygiene practices. The prevalence of tobacco habits is also found to be high due to their long periods of work and constant stress. This study aimed to assess the oral health status and tobacco habits of the government bus drivers and conductors of NWKRTC, Belagavi City, Karnataka.  Methods: A descriptive cross-sectional study was conducted on 451 Government Bus drivers and other employees of NWKRTC who gave consent for the study. WHO Oral Health Assessment Form 2013 was used to record the oral health status and a self-designed, validated questionnaire was employed for recording the oral hygiene practices and tobacco-related habits. Descriptive statistics and Chi-Square was used for statistical analysis.    Results: The mean age of the employees of NWKRTC is 43.55 years and there are 414 males as compared to only 37 females. The mean DMFT score was 5.55±3.08. 228 of them had some kind of tobacco habit with guthka (25.9 percent) being the most prevalent one. 57 employees had manifestations of leukoplakia and OSMF. There was an association between tobacco habits and oral mucosal lesions as well as the DMFT score. Conclusion: The Oral Health Status of the Government employees of NWKRTC is poor. It is further compounded by the high prevalence of tobacco habits and associated lesions and it is a problem that needs to be addressed immediately.

Assessment of knowledge and awareness regarding intellectual property rights among the health-care professionals in Belagavi city: A cross-sectional study

BACKGROUND

Intellectual property rights (IPRs) are increasingly becoming significant for sustainable growth of today's knowledge-based society. An inappropriate knowledge regarding IPR can fail to reserve rights for one's intellectual creation. Hence this study was planned with an aim to assess knowledge, awareness, and practices regarding intellectual property rights in India amongst the health-care professionals in Belagavi city.

MATERIALS AND METHODS

A descriptive cross-sectional study was conducted among the postgraduate students and faculty of six health-care professional institutions in Belagavi, Karnataka. A total of 724 responses were recorded using convenient sampling. Data was collected using self-administered validated questionnaire which included demographic details and total 20 questions pertaining to knowledge, awareness, and practices regarding IPR. Two-point Likert scale was used. Descriptive statistics, Mann-Whitney U-test, and Chi-square test were applied.

RESULTS

A total of 724 responses were recorded, 411 from postgraduate students and 313 from faculty of 6 health-care professional institutions. It was observed that 24.3% and 39.3% of postgraduate students and faculty participants, respectively, had maximum knowledge while 35.5% of faculty and 27.5% of postgraduate students had maximum awareness regarding IPR in India. Only 17.6% and 10.2% of faculty and postgraduate students had previously attended workshops on IPR.

CONCLUSION

The present study identified that both faculty and postgraduate students of health-care profession have less knowledge and awareness regarding IPR. However, both knowledge and awareness regarding IPR were better among faculty when compared to postgraduate students. Thus, the academic community requires a higher level of sensitization and exposure to IPR in India.

Dental caries, oral hygiene status and treatment needs of fishermen and non-fishermen population in South Goa, India

BACKGROUND

Occupation plays a major role in the well-being of an individual and has an influence on oral health. Fishing is one such occupation that entails a lot of physical labour and encourages habits that lead to poor oral health. Therefore, it is critical to shed light on the oral health of this isolated population to improve their quality of life by various means. The aim of the study was to assess and compare the prevalence of dental caries, oral hygiene status and treatment needs of fisherman and non-fisherman population in South Goa, India.

MATERIALS AND METHODS

Study design was cross-sectional in nature. After a pilot study, multi-stage random sampling technique was employed and 400 study participants were recruited. World Health Organization Oral Health Assessment Form (1997) and Oral Hygiene Index-Simplified (OHI-S) were used to record the study variables. Inter-examiner reliability assessed using Kappa statistics were found to be 90% and 88%, respectively. The data was analysed using descriptive analysis, Chi-square test, Mann-Whitney U test, Kruskal-Wallis test, and linear and logistic regression analysis.

RESULTS

Fishermen had significantly higher caries prevalence (82%) and poor oral hygiene (46%) than non- -fishermen. Extraction (42.2%) and pulp care (23.6%) were the highest treatment need among fishermen. They were 2.08 times more prone to dental caries than non-fishermen. Fishermen who used a toothbrush were 4.5 times less susceptible to caries. The dependence of caries prevalence and OHI-S score on occupation, oral hygiene aid and age were 14% and 25.8%, respectively.

CONCLUSIONS

Fishermen in South Goa had high caries prevalence, poor oral hygiene status and they required extensive dental treatment when compared to non-fishermen.

The Oro-Facial Investment Scale (OFIS) - A Novel Outcomes and Evaluation Measure for Self-Appraised Oro-Facial Behavioural and Aesthetic Constructs among Professional Healthcare Students of Belagavi : A Cross-Sectional Study

INTRODUCTION

Several studies have shown that self perceived dental appearance is an important determinant in the decision to seek treatment.

AIM

The aim of the present study was to assess the self-perceived oral health knowledge, attitude, practice, behaviour and perception among 18-20 year old students of professional healthcare institutions in Belagavi city, Karnataka.

MATERIALS AND METHODS

The novel 21 item Oro-Facial Investment Scale (OFIS) formulated for this study was distributed to 600 students of professional healthcare institutions (200 each from Medical, Physiotherapy and Ayurveda specialties respectively). Psychometric properties of the questionnaire were assessed. Descriptive statistics and chi-square test were applied.

RESULTS

Total 98.17% practiced the use of facial and oral care products on a regular basis. All 600 participants disagreed that they hate their facial appearance and the way their teeth looked. Out of 200 Ayurveda students, 37 were unsatisfied with the appearance of their teeth. Also, majority of the respondents agreed that they take prompt care of oral wounds or lesions. While majority of the subjects did not feel conscious when a dentist checks their teeth, a robust 153 respondents expressed their reservations for their dental examination to be performed.

CONCLUSION

The OFIS seamlessly amalgamates the dental unit with the immediate facial components; hence, bringing together, in harmony, a multifaceted dimension in self assessment of the overall facial and dental behavioural practices.

Prevalence of Dental Caries Among Primary School Children of India - A Cross-Sectional Study

INTRODUCTION

In India, the trend indicates an increase in oral health problems especially dental caries, which has been consistently increasing both in prevalence and in severity. Children of all age groups are affected by dental caries. It becomes imperative to collect the data on prevalence of dental caries and treatment needs to provide preventive care.

AIM

To assess the prevalence of dental caries and treatment needs of 6-11years old Indian school children.

MATERIALS AND METHODS

This was a cross-sectional study. Sampling frame consisted of 6-11years old primary school children. Study sample consisted of 13,200 children selected from 10 talukas of Belgavi District, Karnataka, India. Clinical examination for dmft and DMFT was carried out in the school premises by five teams, each consisting of one faculty, three postgraduate students and five interns from the KLE VK Institute of Dental Sciences, Belagavi, Karnataka, India. The examiners were trained and calibrated by the principal investigator. Statistical analysis was done using Chi-square and t-test.

RESULTS

The overall caries prevalence was 78.9%, mean dmft was 2.97±2.62 and mean DMFT was 0.17±0.53. The decayed teeth component was the principal component in both dmft and DMFT indices. The mean dmft in boys was higher compared to girls and it was found to be statistically significant (p<0.05).

CONCLUSION

This study provided us with the baseline data, using which treatment was provided to all the children screened. The children were provided treatment at the camp site/dental hospital/satellite centers and primary health care centers according to the facilities available.

Effect of two herbal mouthwashes on gingival health of school children

This study aimed at determining the effect of indigenously prepared neem and mango chewing stick mouthwashes on plaque and gingival indices. A sample of 105 children aged 12-15 years was randomized into three groups, namely neem, mango, and chlorhexidine mouthwash groups. All the children were examined at baseline and gingival and plaque indices were recorded. Baseline scores for plaque and gingivitis were fair and moderate, respectively, in all the three groups and there existed no statistically significant difference among them. Ten millilitres each of herbal and chlorhexidine mouthwashes (0.2%) were administered according to the group allocation twice daily for 21 days. Indices were reassessed at 21 days (immediately after intervention) and at 1 month, 2 months, and 3 months after discontinuing the mouthwashes. Statistically significant reduction (P < 0.001) in plaque index was found in all the three mouthwash groups at 21 days and at 1 month from discontinuing the mouthwash. Chlorhexidine additionally showed statistically significant reduction in plaque index at 2 months from discontinuing the mouthwash. Statistically significant reduction (P < 0.001) in gingival index was found in all the three mouthwash groups at 21 days (immediately after discontinuing the mouthwash) and at 1 and 2 months from discontinuing the mouthwash. To conclude, all the three mouthwashes were effective antiplaque and antigingivitis agents. Chlorhexidine and neem possess equivalent efficacy in reducing plaque, while chlorhexidine has superior antigingivitis properties.

Comparison of effectiveness of abrasive and enzymatic action of whitening toothpastes in removal of extrinsic stains - a clinical trial

OBJECTIVE

To compare the effectiveness of abrasive component (perlite/calcium carbonate) and enzymatic component (papain and bromelain) of whitening toothpaste in removal of extrinsic stains.

METHODS

This study is a randomized, triple blind and parallel group study in which 90 subjects aged 18-40 years were included. At baseline, stains scores were assessed by Macpherson's modification of Lobene Stain Index and subjects were randomly assigned to two groups with 45 subjects in each. Group 1 used whitening toothpaste with enzymatic action and group 2 with abrasive action. After 1 month, stain scores were assessed for the effectiveness of the two toothpastes and 2 months later to check the stain prevention efficacy. Wilcoxson's test was used to compare between baseline 1 and 2 months stain scores, and Mann-Witney U-test was applied for intragroup comparison.

RESULTS

The mean baseline total stain score for the subjects allocated to the enzymatic toothpaste was 37.24 ± 2.11 which reduced to 30.77 ± 2.48 in 1 month, and for the abrasive paste, total stain reduced from 35.08 ± 2.96 to 32.89 ± 1.95. The reductions in total stain scores with both the pastes were significant compared with baseline stain scores (at 1 month Group 1, P = 0.0233 and Group 2, P = 0.0324; at 2 months, Group 1 P = 0.0356). Both the toothpastes proved to be equally good in removal of extrinsic stains; however, the enzymatic paste showed better results as compared to abrasive toothpaste.

CONCLUSION

Whitening toothpaste with abrasive action and enzymatic action are equally effective in removal of extrinsic stains; however, whitening toothpaste with abrasive action needs to be used with caution.

An in vitro study to determine the effect of Terminalia chebula extract and its formulation on Streptococcus mutans

AIM

Many weapons are available in the arsenal of a dental professional to combat dental caries, which is almost ubiquitously present. From a public health perspective, most of these weapons are far from being an ideal drug. Hence, there is a demand for better and effective antibacterial agents. This factor stimulated the process of the present study. The aim of the study was to determine the effect of ethanol extract of Terminalia chebula on Streptococcus mutans.

MATERIALS AND METHODS

Dried ripe fruits of Terminalia chebula were procured and powdered. Physical tests were done to estimate purity of the fruit powder. Hydroethanolic and aqueous extracts were prepared according to standard procedures. Minimum inhibitory concentration of the extracts was determined by tube dilution method and confirmed by agar dilution method. The effect of the hydroethanolic extract on sucrose induced adhesion, glucan-induced aggregation and on glycolysis of Streptococcus mutans was also assessed. Preservative, gelling agent and sweetener were added in suitable quantities to the ethanol extract, and mouthrinse was formulated. Minimum inhibitory concentration of the formulation was also determined.

RESULTS

Yield was better in case of aqueous extract. The Minimum inhibitory concentration of hydroethanolic extract was determined to be 2.5%. Minimum inhibitory concentration of the aqueous extract was determined to be 10%. Hydroethanolic extract of Terminalia chebula (2.5%) inhibited sucrose induced adherence and aggregation of Streptococcus mutans in vitro.

CONCLUSION

The mouthrinse formulated from ethanol extract of Terminalia chebula demonstrated substantial antibacterial activity and could be used as an effective anticaries agent.

CLINICAL SIGNIFICANCE

Terminalia chebula mouthrinse can be effectively used in clinical practice as an anticaries mouthrinse with additional benefit being that it is safe and economical.

Aesthetic perceptions regarding fluorosis by children from an area of endemic fluorosis in India

OBJECTIVES

To assess the perceptions of and concerns regarding dental fluorosis among 12-15 year-old schoolchildren in an area where fluorosis is endemic and to find any association with Tooth Surface Index of Fluorosis (TSIF) scores.

BASIC RESEARCH DESIGN

A cross sectional study.

PARTICIPANTS

316 children aged 12-15 years with varying level of dental fluorosis selected from 696 children screened for fluorosis.

METHODS

The study was undertaken in three villages in rural Gadag, Karnataka, India, with fluoride levels in the drinking water ranging from 2.2 to 4.5 ppm as estimated by the SPADNS spectrophotometric method. Children's fluorosis was assessed under natural lighting conditions on the labial surface of upper anterior teeth using the TSIF 8-point scale. A self-administered questionnaire assessed knowledge, perceptions and concerns. Data were analysed by frequency distributions and Spearman's correlation coefficients.

MAIN OUTCOME MEASURES

Aesthetic perceptions and TSIF scores.

RESULTS

The children were aware of the fluoride presence and its health effects. TSIF scores correlated with: the appearance of front teeth (r = 0.135, p = 0.015); feeling fluorosis would hinder smiling (r = 0.116, p = 0.040); feeling distress due to fluorosis (r = 0.111, p = 0.048).

CONCLUSION

Children were aware of fluoride and its health effects. They also perceived dental fluorosis as an aesthetic problem.

Optimizing human factors in dentistry

Occupational health hazards among dental professionals are on a continuous rise and they have a significant negative overall impact on daily life. This review is intended to provide the information regarding risk factors and to highlight the prevention strategies for optimizing human factors in dentistry. Risk factors among dentists are multifactorial, which can be categorized into biomechanical and psychosocial. To achieve a realistic target of safety and health at work, prevention is clearly the best approach; therefore, musculoskeletal disorders can be reduced through proper positioning of dental worker and patient, regular rest breaks, general good health, using ergonomic equipment, and exercises designed to counteract the particular risk factors for the dental occupation. However, substantial evidences are still required to elucidate the potential risk factors and to formulate effective prevention programs.

Indian dental students' attitudes and practices regarding tobacco cessation counseling

Tobacco cessation counseling (TCC) has been proven to be very effective in helping tobacco users to quit. Dentists can play a vital role in helping patients to quit tobacco use. The aim of this study was to examine five groups of Indian dental students' attitudes and practices regarding TCC. Out of 514 fifth-year students in five colleges of Karnataka, India, 456 students voluntarily participated. The thirty-five-item questionnaire consisted of four sections: demographic characteristics, practices in the institution, attitudes toward tobacco cessation programs in the dental setting, knowledge of tobacco counseling, and perceived barriers in counseling. To test the reliability of the survey items, Cronbach's alpha coefficient was used. Frequency distributions and percentages were examined for each item, and chi-square tests were used to analyze differences based on tobacco usage status. The sample consisted of 317 female and 139 male students. The majority of the students (n=429, 94 percent) reported that they give anti-tobacco usage advice to patients who smoke and planned to advise patients about tobacco cessation throughout their careers. Fewer students (n=314, 68.9 percent) indicated that such counseling would assist patients to quit. The major barriers were reported to be patients' resistance, inadequate skills, and poor knowledge about nicotine replacement therapy. This study found that these students had a positive attitude about TCC, along with adequate knowledge regarding the ill effects of tobacco. However, this study concludes that tobacco cessation should be given greater emphasis in the curriculum of Indian dental schools in order to expand the use of TCC in dental practices.

Perlecan (basement membrane heparan sulfate proteoglycan) and its role in oral malignancies: an overview

Perlecan means pearl-like structures. Perlecan is a large proteoglycan (400-500 kDa) present in virtually all vascularized tissues with a distribution that is primarily confined to basement membranes including those of oral mucosa. It is a basement membrane-type heparan sulfate proteoglycan. Perlecan is synthesized by basal cells and fibroblasts adjacent to the basal lamina . Perlecan is also synthesized by vascular endothelial and smooth muscle cells present in the extracellular matrix. It has been demonstrated in recent years that perlecan is distributed in the stromal space of various pathophysiological conditions. The complex pleiotropy of perlecan suggests that this gene product is involved in several developmental processes, at both early and late stages of embryogenesis, as well as in cancer and diabetes. In the oral cavity, perlecan expression is reported to basal cells in normal mucosa and its expression increases in precancer and cancerous conditions. It is also expressed in various odontogenic tumors such as ameloblastoma, keratocyst odontogenic tumor, and also salivary gland tumors such as adenoid cystic carcinoma, mucoepidermoid carcinoma, etc.

Association of erosion with dietary factors among 5-year-old children in India

PURPOSE

The purpose of this study was to determine the association of dental erosion with dietary factors and oral hygiene practices among 5-year-old schoolchildren in Belgaum, Karnataka, India.

METHODS

A random sample of 1,002 5-year-old children was drawn from Belgaum schools. Erosion was assessed using the modified Smith and Knight index. A self-designed questionnaire was used to probe into the details of the children's dietary practices.

RESULTS

Frequency of consumption of beverages, canned juices, tamarind, and honey, a mixed diet, and frequency of teeth cleaning were significant predictors of dental erosion. Oral hygiene practices like timing of cleaning teeth and materials used did not show significant association with dental erosion.

CONCLUSION

Certain dietary factors like canned juice, raw mango, gooseberry, tamarind, honey, buttermilk, and beverages showed significant correlation with dental erosion. Dietary counseling must take this into consideration.

Effectiveness of mouthrinse formulated from ethanol extract of Terminalia chebula fruit on salivary Streptococcus mutans among 12 to 15 year old school children of Belgaum city: a randomized field trial

OBJECTIVES

Dental caries is the most prevalent oral disease. Streptococcus mutans plays a major role in the occurrence of dental caries. Many antibacterial agents have been developed against dental caries. However, they lack the qualities of an ideal agent. Thus presently, antibacterial activity of herbal agents is being extensively studied.

MATERIALS AND METHODS

In the present study, ethanol extract of Terminalia chebula was prepared and mouthrinse was formulated. A total of 60 children meeting the inclusion criteria were randomly divided into study and control group and respective mouthrinses were administered. Salivary Streptococcus mutans count was assessed at 5 and 60 minutes after rinsing and compared with baseline values. Substantivity of the rinse was assessed among 10 children. Mouthrinse was given to the children and salivary Streptococcus mutans counts were assessed at baseline, 6 and 12 hours postrinsing. Mann-Whitney U test was used to assess the variance of factors like Decayed Missed Filled Teeth, plaque scores, and gingival scores. ANCOVA (Analysis of covariance) was used to determine the change in salivary Streptococcus mutans colony forming units taking baseline values as covariates.

RESULTS

It was observed that there was 44.42% reduction in salivary Streptococcus mutans colony forming units 5 minutes after rinsing as compared with baseline values and 64.14% reduction in Streptococcus mutans colony forming units at 60 minutes after rinsing as compared with baseline values. There was a reduction of 35.48% in salivary Streptococcus mutans colony forming units at 60 minutes after rinsing as compared with 5 minutes sample.

CONCLUSION

Streptococcus mutans counts were low up to 6 hours postrinsing among 80% of the children.

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.

Feeding habits and oral hygiene practices as determinants of early childhood caries in 3- to 5-year-old children of Belgaum City, India

PURPOSE

To investigate whether feeding and oral hygiene practices of preschool children are associated with the risk and prevalence of Early Childhood Caries (EC).

MATERIALS AND METHODS

A cross-sectional study comprising 1250 children aged 3 to 5 years from Belgaum was designed. On the first day, validated questionnaires along with parental informed consent forms were distributed to the children and were collected after a week. Validated questionnaires consisted of 20 close-ended questions pertaining to feeding and oral hygiene practices. Consent was obtained from parents of the 1116 children who were examined for EC. Data analysis included correlation coefficients and logistic regressions.

RESULTS

Among the children studied, 97.3% were breastfed, of which 41.25% were breastfed until 2 years of age. Seventy- five percent of children who were breastfed beyond 2 years were affected by EC. Exclusive bottle feeding was practiced in 46.15%; 64.85% of them suffered from EC. Burping was not practiced in 25.18%, and 68.68% of these were affected by EC. EC was more prevalent in 89% of children who were weaned later than 12 months of age. Parental assistance for oral hygiene was not seen in 37.27% and 67.22% of these suffered from EC. Overall, 63.17% of the children were affected by EC.

CONCLUSION

Prolonged breastfeeding, absence of burping the child, delay in starting oral hygiene practices and lack of parental assistance with the same were shown to be significant determining factors for EC. Health education and proper guidelines on feeding and oral hygiene practices can substantially reduce the risk and prevalence of EC.

Effectiveness of herbal and fluoridated toothpaste on plaque and gingival scores among residents of a working women's hostel - a randomised controlled trial

PURPOSE

To determine the effectiveness of herbal and fluoridated toothpastes on plaque and gingival scores among 18- to 25-year-old female participants residing in a working women's hostel.

MATERIALS AND METHODS

Sixty participants residing in a working women's hostel in Belgaum city, aged between 18 and 25 years, comprised the study population. The 60 participants were randomly allocated to the experimental and control groups. The experimental group was asked to use a herbal toothpaste (Himalaya Herbal Healthcare) and the control group a fluoridated toothpaste (Colgate Dental Cream) twice a day for 6 weeks. The plaque and gingival indices were recorded according to Silness and Löe (1964) and Löe and Silness (1963), respectively, at baseline, 3 weeks and 6 weeks of usage of the toothpastes.

RESULTS

Baseline plaque and gingival scores were 1.53 ± 0.9 and 1.22 ± 0.13 for the control group and 1.30 ± 0.15 and 1.19 ± 0.12 for the experimental group, respectively. At 6 weeks, plaque and gingival scores were 0.86 ± 0.18 and 0.80 ± 0.2 for the control group and 0.99 ± 0.14 and 0.9 ± 0.21 for the experimental group, respectively. Statistically significant differences were obtained before and after the intervention in both groups (P < 0.001).

CONCLUSION

The herbal toothpaste was as effective as the conventionally formulated dentifrice in controlling plaque and gingivitis.

Periodontal health status among permanent residents of low, optimum and high fluoride areas in Kolar District, India

PURPOSE

To assess and compare the periodontal health status among permanent residents of low, optimum and high fluoride areas in Kolar District, India.

MATERIALS AND METHODS

A house-to-house survey was conducted in a population consisting of 925 permanent residents aged 35 to 44 years in three villages having different levels of fluoride concentrations in the drinking water. The fluoride concentrations in selected villages were 0.48 ppm (low), 1.03 ppm (optimum) and 3.21 ppm (high). The ion selective electrode method was used to estimate the fluoride concentration in the drinking water. Periodontal status was assessed using the Community Periodontal Index (CPI) and loss of attachment (LOA). Results were analysed using the chi-square test and logistic regression. The chi-square test was used to find the group differences and logistic regression to find association between the variables.

RESULTS

The overall prevalence of periodontitis was 72.9%; specifically, prevalences were 95.4%, 76.3% and 45.7% in low, optimum and high fluoride areas, respectively. The number of sextants with shallow or deep pockets decreased (shallow pockets: 525, 438, 217; deep pockets: 183, 81, 34) from low to high fluoride areas (odds ratio: 71.3). The low fluoride area had a 7.9-fold higher risk of periodontitis than the optimum fluoride area and a 30-fold higher risk than the high fluoride area, which was highly significant (χ2 = 53.5, P < 0.0001 and χ2 = 192.8, P < 0.001, respectively).

CONCLUSIONS

The severity of periodontal disease is inversely associated with the fluoride concentrations in drinking water. This relation can provide an approach to fluoride treatments to reduce the prevalence or incidence of this disease.

Mobile-phone text messaging (SMS) for providing oral health education to mothers of preschool children in Belgaum City

We compared the effectiveness of two media (text messages and pamphlets) in imparting health education to mothers of preschool children. Mothers and their children were randomized into two groups. There were 72 mothers and their children in the pamphlet group and 71 in the text message group. The mothers were given health education by one of the two modes for four weeks. Knowledge, attitude and practices of the mothers were assessed by a questionnaire pre- and post-intervention. Visible plaque scores of their children were also recorded pre- and post-intervention. There were significant improvements in knowledge (P < 0.001), attitude (P < 0.001) and practices (P < 0.001) in both groups. There was also a significant reduction in visible plaque scores (P < 0.001) in both groups. Text messaging was more effective than pamphlets in improving knowledge, attitude and practices of mothers, but the comparative reduction in plaque score between groups was not significant. Text messaging appears to be an effective means of imparting oral health education.
