The impact of perinatal and at birth risk factors on the progression from preschool wheezing to adolescent asthma.

Asthma is a global health concern affecting millions of children and adolescents. This review focuses on the possible factors that are associated with the transition from preschool wheezing to childhood asthma and highlights the significance of early-life environmental exposures during pregnancy and the first 6 months of life in shaping allergies and asthma. We observed a scarcity of studies investigating this subgroup, with most focusing on wheezing trajectories. We undertook a thorough investigation of diverse perinatal exposures that have the potential to impact this transition. These factors include maternal asthma, smoking during pregnancy, diet, prepregnancy weight, infant birthweight, gestational age, and breastfeeding. Although limited, studies do suggest that maternal asthma increases the likelihood of preschool wheeze in offspring that persists through childhood with potential asthma progression. Findings concerning other perinatal exposures remain inconsistent. Further research is needed to identify asthma progression risk factors and assess perinatal exposure effects.

Does oral iron and folate supplementation during pregnancy protect against adverse birth outcomes and reduced neonatal and infant mortality in Africa: A protocol for a systematic review and meta-analysis?

BACKGROUND: Globally, one-third of pregnant women are at risk of iron deficiency, particularly in the African region. While recent findings show that iron and folate supplementation can lower the risk of adverse birth outcomes and childhood mortality, our understanding of its impact in Africa remains incomplete due to insufficient evidence. This protocol outlines the systematic review steps to investigate the impact of oral iron and folate supplementation during pregnancy on adverse birth outcomes, neonatal mortality and infant mortality in Africa. METHODS AND ANALYSIS: MEDLINE, PsycINFO, Embase, Scopus, CINAHL, Web of Science, and Cochrane databases were searched for published articles. Google Scholar and Advanced Google Search were used for gray literature and nonindexed articles. Oral iron and/or folate supplementation during pregnancy is the primary exposure. The review will focus on adverse birth outcomes, neonatal mortality and infant mortality. Both Cochrane Effective Practice and Organization of Care and Newcastle-Ottawa Scale risk of bias assessment tools will be used. Meta-analysis will be conducted if design and data analysis methodologies permit. This systematic review and meta-analysis will provide up-to-date evidence about iron and folate supplementation's role in adverse birth outcomes, neonatal mortality and infant mortality in the African region. ETHICS AND DISSEMINATION: This review will provide insights that help policymakers, program planners, researchers, and public health practitioners interested in working in the region.

Grass pollen exposure is associated with higher readmission rates for pediatric asthma.

BACKGROUND: Pediatric asthma hospital readmission is a burden on the individual and costly for Australian hospitals. Grass pollen's role, a known trigger for asthma admissions, is unexamined in readmissions. We examined the association between grass pollen and pediatric asthma readmission. METHODS: The Victorian Admitted Episodes Dataset was used to identify all primary admissions with a principal diagnosis of asthma in children aged 2-18 years between 1997 and 2009. Readmissions were defined as subsequent admissions within 28 days of index admission discharge. Generalized additive models were used to assess associations between readmission, grass pollen season, and daily grass pollen counts, lagged and cumulative. Models were further stratified by sex and age group. RESULTS: Mean daily readmission was higher during grass pollen season than other times of the year, incidence rate ratio (IRR) 1.44 (95% CI, 1.03, 2.02) and for children aged 2-5 years, IRR 1.99 (1.26, 3.14). Same day grass pollen was nonlinearly associated with daily readmission for the 13-18 age group between 110 and 256 grains/m3 , p < .01. Lag 2 grass pollen was nonlinearly associated with daily readmissions overall (p = .03), boys (p = .01), and younger age groups 2-5 (p = .02) and 6-12 (p < .001). CONCLUSIONS: Grass pollen exposure was associated with higher readmission rates for pediatric asthma. Treatment plans prior to discharge could be implemented to reduce the likelihood of readmission by younger children during the pollen season.

The association between outdoor allergens - pollen, fungal spore season and high asthma admission days in children and adolescents.

Periods when asthma admissions peaks have serious implications for asthma sufferers and hospitals. We assessed the association between aeroallergen exposure and childhood asthma peak periods during two grass pollen seasons using the Melbourne Air Pollen Children and Adolescent Health (MAPCAH) study conducted in Melbourne, Australia. Two peak periods were identified. Effect modifications by atopy and sex were considered. All pollen 2 days prior was associated with increased odds of these peak periods. Same day fungal spores, but not pollen, were important. Grass at lag 2 was associated with increased odds 1.03 (95%CI 1.01, 1.05) as was the same day Alternaria 1.02 (1.00, 1.04) per spore/m3 for boys. In addition to pollen, fungal spores particularly Alternaria may result in days of high exacerbations during pollen seasons. Further guidance is needed to better prepare families/carers with information about the increased risk of asthma attacks in children prior to pollen seasons.

Antimicrobial Effect of Jasminum grandiflorum L. and Hibiscus rosa-sinensis L. Extracts Against Pathogenic Oral Microorganisms--An In Vitro Comparative Study.

PURPOSE: To assess and compare the antimicrobial potential and determine the minimum inhibitory concentration (MIC) of Jasminum grandiflorum and Hibiscus rosa-sinensis extracts as potential anti-pathogenic agents in dental caries. MATERIALS AND METHODS: Aqueous and ethanol (cold and hot) extracts prepared from leaves of Jasminum grandiflorum and Hibiscus rosa-sinensis were screened for in vitro antimicrobial activity against Streptococcus mutans and Lactobacillus acidophilus using the agar well diffusion method. The lowest concentration of every extract considered as the minimum inhibitory concentration (MIC) was determined for both test organisms. Statistical analysis was performed with one-way analysis of variance (ANOVA). RESULTS: At lower concentrations, hot ethanol Jasminum grandiflorum (10 µg/ml) and Hibiscus rosa-sinensis (25 µg/ml) extracts were found to have statistically significant (P≤0.05) antimicrobial activity against S. mutans and L. acidophilus with MIC values of 6.25 µg/ml and 25 µg/ml, respectively. A proportional increase in their antimicrobial activity (zone of inhibition) was observed. CONCLUSION: Both extracts were found to be antimicrobially active and contain compounds with therapeutic potential. Nevertheless, clinical trials on the effect of these plants are essential before advocating large-scale therapy.

Effect of Chocobar Ice Cream Containing Bifidobacterium on Salivary Streptococcus mutans and Lactobacilli: A Randomised Controlled Trial.

PURPOSE: To examine the effect of chocobar ice cream containing bifidobacteria on salivary mutans streptococci and lactobacilli. MATERIALS AND METHODS: A double-blind, randomised controlled trial was conducted with 30 subjects (18 to 22 years of age) divided into 2 groups, test (chocobar ice cream with probiotics) and control (chocobar ice cream without probiotics). The subjects were instructed to eat the allotted chocobar ice cream once daily for 18 days. Saliva samples collected at intervals were cultured on Mitis Salivarius agar and Rogosa agar and examined for salivary mutans streptococci and lactobacilli, respectively. The Mann-Whitney U-test, Friedman and Wilcoxon signed-rank tests were used for statistical analysis. RESULTS: Postingestion in the test group, a statistically significant reduction (p < 0.05) of salivary mutans streptococci was recorded, but a non-significant trend was seen for lactobacilli. Significant differences were was also observed between follow-ups. CONCLUSION: Short-term daily ingestion of ice cream containing probiotic bifidobacteria may reduce salivary levels of mutans streptococci in young adults.

The Effects of Maternal Iron and Folate Supplementation on Pregnancy and Infant Outcomes in Africa: A Systematic Review.

BACKGROUND: Iron and folate deficiency are prevalent in pregnant women in Africa. However, limited research exists on the differential effect of oral iron-only, folate-only, or Iron Folic Acid (IFA) supplementation on adverse pregnancy and infant outcomes. This systematic review addresses this gap, focusing on studies conducted in Africa with limited healthcare access. Understanding these differential effects could lead to more targeted and potentially cost-effective interventions to improve maternal and child health in these settings. METHODS: A systematic review was conducted following PRISMA guidelines. The primary exposures were oral iron-only, folate-only, or IFA oral supplementation during pregnancy, while the outcomes were adverse pregnancy and infant outcomes. A qualitative synthesis guided by methods without meta-analysis was performed. RESULTS: Our qualitative synthesis analysed 10 articles reporting adverse pregnancy (adverse birth outcomes, stillbirths, and perinatal mortality) and infant outcomes (neonatal mortality). Consistently, iron-only supplementation demonstrated a reduction in perinatal death. However, evidence is insufficient to assess the relationship between iron-only and IFA supplementation with adverse birth outcomes, stillbirths, and neonatal mortality. CONCLUSION: Findings suggested that iron-only supplementation during pregnancy may reduce perinatal mortality in African women. However, evidence remains limited regarding the effectiveness of both iron-only and IFA supplementation in reducing stillbirths, and neonatal mortality. Moreover, additional primary studies are necessary to comprehend the effects of iron-only, folate-only, and IFA supplementation on pregnancy outcomes and infant health in the African region, considering rurality and income level as effect modifiers.

Barriers and Enablers of Diabetes Self-Management Strategies Among Arabic-Speaking Immigrants Living with Type 2 Diabetes in High-Income Western countries- A Systematic Review.

The aim of this review is to investigate barriers and enablers of diabetes self-management strategies among migrant Arabic-speaking background [ASB] individuals living with type 2 diabetes in high-income Western countries. Despite living in high-income Western countries, individuals from ASB are perceived to have difficulties adopting self-management strategies and this necessitates gaining an understanding of factors that may impact the uptake of these strategies. Ten studies are included in this review: five quantitative and five qualitative. Quality assessment was conducted using the Joanna Briggs Institute Critical Appraisal and Hawker tools. The findings of the quantitative studies were descriptively analysed, while thematic analysis was performed for the qualitative studies. The results indicate that individuals from ASB are perceived to have low levels of adherence to diabetes self-management. It is also suggested that participants who did not complete high school have poorer glycaemic control compared to those with a high school qualification (30 vs. 16%). Regular exercise was reported to be less likely to be adopted by ASBs homemakers, and those who were unemployed, by 82% and 70%, respectively, compared to those employed (homemakers: OR = 0.187, P = 0.006; 95% CI = 056-0.620), (unemployed OR = 0.30, P = 0.046; 95% CI = 0.093-0.980). Cultural, social, religious beliefs, lack of knowledge and language barriers are some of the factors identified that impact self-management among ASB individuals. It is suggested that diabetes self-management education program (DSME) tailored to ASB immigrants culture may be an effective way to encourage them to uptake self-management strategies.

Is the addition of running retraining to best standard care beneficial in runners with medial tibial stress syndrome? Protocol for a randomised controlled trial.

BACKGROUND: Running retraining is commonly used in the management of medial tibial stress syndrome (MTSS) but evidence for its effectiveness is lacking. The primary aim of this study is to determine if the addition of running retraining to best standard care is beneficial in the management of runners with MTSS. METHODS: This study is an assessor-blinded and participant-blinded, parallel-group, randomised controlled trial. The trial will recruit 64 participants aged between 18 and 45 years, with a clinical diagnosis of MTSS that has affected their running participation for at least four weeks. Participants will be randomised to receive best standard care (control) or running retraining and best standard care (intervention group) over an 8-week period. Best standard care will consist of load management advice, symptom management advice, footwear advice and a strengthening program. Running retraining will consist of a cue to reduce running step length. Outcomes will be measured at weeks 1, 2, 4 and 8. The primary outcome measure will be the University of Wisconsin Running Injury and Recovery Index at week 4. Secondary outcome measures include: (i) Exercise Induced Leg Pain Questionnaire-British Version, (ii) global rating of change scale, (iii) worst pain experienced during a run, (iv) weekly run volume, (v) reactive strength index score, (vi) single leg hop test, (vii) soleus single leg maximum voluntary isometric contraction, (viii) gastrocnemius single leg maximum voluntary isometric contraction, (ix) single leg plantar flexor endurance test, (x) running step length, and (xi) running step rate. Data will be analysed using the intention-to-treat principle. DISCUSSION: This randomised controlled trial will evaluate if reducing running step length provides additional benefit to best standard care in the management of runners with MTSS over an 8-week period.

Knowledge and attitude towards smoking among Indian students of dentistry.

UNLABELLED: Active cigarette smoking is the major cause of lung cancer and an important established cause of cardiovascular disease mortality. Risks have been shown to increase with even light or intermittent active smoking. OBJECTIVES: To assess the prevalence of smoking, age of initiation and the knowledge and attitude towards smoking among dental college students of Rajasthan, India. METHODS: A cross-sectional study was conducted among 1,383 undergraduate and postgraduate dental college students of Rajasthan using self-administered closed-ended questionnaires consisting of 14 questions divided into four sections. A chi-square test was used to determine the association between dependent and independent variables. RESULTS: Of all the participants, 777 (56.2%) were male and 606 (43.8%) were female. Among these 258 (33.2%) males and 51 (8.4%) females had tried or experimented smoking. Majority of males (24.7%) initiated this habit at a very young age, before 16 years. About 79.5% males and 72.3% females felt that it was difficult to quit smoking. According to 88.1% females and 48.7% males, people feel less comfortable at public places or social gatherings. CONCLUSION: The study has shown that the smoking prevalence among dental college students is high and has managed to contribute additional information regarding their attitude towards smoking. Comprehensive tobacco education and smoking cessation programmes should be aggressively promoted in dental settings.

Nonsurgical management of hallux valgus: findings of a randomised pilot and feasibility trial.

BACKGROUND: Hallux valgus is a common and disabling condition. This randomised pilot and feasibility trial aimed to determine the feasibility of conducting a parallel group randomised trial to evaluate the effectiveness of a nonsurgical intervention for reducing pain associated with hallux valgus. METHODS: Twenty-eight community-dwelling women with painful hallux valgus were randomised to receive either a multifaceted, nonsurgical intervention (footwear, foot orthoses, foot exercises, advice, and self-management) or usual care (advice and self-management alone). Outcome measures were obtained at baseline, 4, 8 and 12 weeks. The primary outcome was feasibility, evaluated according to demand (recruitment rate and conversion rate), acceptability, adherence, adverse events, and retention rate. Limited efficacy testing was conducted on secondary outcome measures including foot pain, foot muscle strength, general health-related quality of life, use of cointerventions, and participants' perception of overall treatment effect. RESULTS: Between July 8, 2021, and April 22, 2022, we recruited and tested 28 participants (aged 44 to 80 years, mean 60.7, standard deviation 10.7). This period encompassed two COVID-related stay-at-home orders (July 16 to July 27, and August 5 to October 21, 2021). The predetermined feasibility thresholds were met for retention rate, foot pain, mental health-related quality of life, and use of cointerventions, partly met for acceptability, adverse events, and muscle strength, and not met for demand (recruitment rate or conversion rate), adherence, physical health-related quality of life and perception of overall treatment effect. CONCLUSION: In its current form, a randomised trial of footwear, foot orthoses, foot exercises, advice and self-management for relieving pain associated with hallux valgus is not feasible, particularly due to the low adherence with the intervention. However, it is difficult to determine whether the trial would be feasible under different circumstances, particularly due to COVID-19 stay-at-home orders. Future trials will need to consider improving the aesthetics of the footwear and making the exercise program less burdensome.

Asthma Hospital Admission and Readmission Spikes, Advancing Accurate Classification to Advance Understanding of Causes.

BACKGROUND: An important component of asthma care is understanding potential causes of high asthma admissions (HAADs) or readmissions (HARDs) with potential of risk mitigation. Crucial to this research is accurately distinguishing these events from background seasonal changes and time trends. To date, classification methods have been based on ad hoc and untested definitions which may hamper understanding causes of HAADs and HARDs due to misclassification. The aim of this article is to introduce an easily applied robust statistical approach, with high classification accuracy in other settings-the Seasonal Hybrid Extreme Studentized Deviate (S-H-ESD) method. METHODS: We demonstrate S-H-ESD on a time series between 1996 and 2009 of all daily paediatric asthma hospital admissions in Victoria, Australia. RESULTS: S-H-ESD clearly identified HAADs and HARDs without applying ad hoc classification definitions, while appropriately accounting for seasonality and time trend. Importantly, it was done with statistical testing, providing evidence in support of their identification. CONCLUSION: S-H-ESD is useful and statistically appropriate for accurate classification of HAADs and HARDS. It obviates ad hoc approaches and presents as a means of systemizing their accurate classification and detection. This will strengthen synthesis and efficacy of research toward understanding causes of HAADs and HARDs for their risk mitigation.

The Effect of Outdoor Environmental Exposure on Readmission Rates for Children and Adolescents with Asthma-A Systematic Review.

The burden of asthma readmission for children and adolescents is approximately 10% worldwide. Research has been synthesised for behavioural and indoor impacts; however, no such synthesis has been conducted for outdoor environmental exposures. This systematic review aims to evaluate and synthesise the impact the outdoor environment has on readmission rates for children or adolescents with asthma. We conducted a systematic search of seven databases and hand searched reference lists of articles published up until 18 January 2021. There were 12 out of 392 studies eligible for inclusion. Overall, most studies showed that outdoor environments impact on readmission; however, the strength of association is seen to be stronger in a particular subpopulation of each study depending on the exposure investigated. The evidence for the association between outdoor environmental exposure and readmission rates for children or adolescents with asthma is increasing; however, it is complicated by potential confounders such as socioeconomic factors, ethnicity, indoor air pollutants, and other behavioural factors. Further research is required to differentiate between them. Additionally, further studies need to be undertaken in further countries other than the United States of America to understand the full relationship.

Impact of Individual, Familial and Parental Factors on Adolescent Smoking in Turkey.

The burden of adolescent cigarette smoking is substantial. We assess mothers' and fathers' attitudes and behaviours on adolescent smoking using a cross-sectional study of n = 707 adolescents. Associations between parental attitudes and behaviours in adolescent smoking were assessed using logistic regression separately for boys and girls. Occasional alcohol use by both parents increased odds of smoking once a day (OR = 2.44, 95% CI 1.26, 4.71, OR = 1.51, 95% CI 0.97, 2.35, respectively). Fathers smoking increased odds for girls (OR = 1.59, 95% CI 1.01, 2.52). A democratic mother decreased odds for boys (OR = 0.32, 95% CI 0.10, 0.93) whereas a protective, demanding mother increased the odds for girls (OR = 8.65, 95% CI 1.38, 54.22). Public health smoking prevention programs could support changing parental behaviours and attitudes in early years to address this burden in countries with authoritarian parenting styles.

A systematic review of the evidence of outdoor air pollution on asthma hospital visits in children and adolescents in South Asia - a call for data.

Background: Outdoor air pollution and childhood asthma are increasing problems in South Asian countries. However, little is known about the associations between levels of air pollution and severe childhood asthma requiring hospital treatment in these regions. Methods: We undertook a systematic review to assess the evidence between outdoor air pollution exposure and childhood and adolescent asthma hospitalization in South Asia. MEDLINE, Web of Science, Google Scholar, CINAHL, Embase, Scopus, ProQuest Central databases were searched for peer-reviewed papers, and examination of reference lists was conducted for additional studies. We identified all the literature published in English up to January 2021 for the study population comprised of children aged less than 19 years. The search strategy was designed to identify all the studies and screen them as per the inclusion criteria. The method of qualitative synthesis using the standard tool determined the comprehensiveness of the assessment of bias. Results: Of the original 367 studies screened three studies were ultimately included from India, Pakistan and Sri Lanka and a narrative synthesis was conducted. Although studies reported adverse effects of outdoor pollution on asthma hospitalizations, limitations in exposure assessments, varying definitions of asthma hospitalizations and limited data analysis were identified. Conclusions: There is currently limited evidence that can provide meaningful risk estimates of the impact of outdoor air pollution on asthma hospitalizations during childhood and adolescence. Studies with comparable outcome definitions, appropriate exposure assessments and study designs are needed to inform future public and environmental health policy.

Community Response to the Impact of Thunderstorm Asthma Using Smart Technology.

BACKGROUND: The most severe thunderstorm asthma (TA) event occurred in Melbourne on the 21st November 2016 and during this period, daily pollen information was available and accessible on smart devices via an App. An integrated survey within the App allows users to self-report symptoms. OBJECTIVE: To explore patterns of symptom survey results during the period when the TA event occurred. METHODS: Symptom data from the Melbourne Pollen Count and Forecast App related to asthma history, hay fever symptoms, and medication use was explored. A one-week control period before and after the event was considered. Chi-square tests and logistic regression were used to assess associations between sex, age, symptoms, and medication use. RESULTS: Of the 28,655 responses, during the 2016 pollen season, younger (18 to 40 years) males, with no hay fever and no asthma were the most single and regular responders. During the TA event for new users, sex was only significantly associated with hay fever (p = 0.008) of which 60.2% of females' responses reported having hay fever, while 43% of males' responses did not. Those with mild symptoms peaked during the TA event. CONCLUSIONS: Many individuals completed the survey on the app for the first time during the TA event indicating the potential of digital technologies to be used as indicators of health risk among populations at risk of TA events.

Oral Health Beliefs, Attitudes, and Practices of South Asian Migrants: A Systematic Review.

Oral health is a burden among all populations and is linked with major chronic diseases such as cardiovascular diseases. Migrants, in particular South Asians, have poor oral health which requires further understanding to better inform oral health interventions by targeting specific aspects of this heterogenous South Asian population. This review is undertaken to systematically synthesize the evidence of oral health understandings, knowledge, attitudes, beliefs, practices, and behaviors of South Asian migrants residing in high-income countries. A comprehensive systematic search of seven electronic databases and hand-searching for peer-reviewed studies was conducted. All study designs were included, and quality assessment conducted. Of the 1614 records identified, 17 were included for synthesis and 12 were quantitative in design. These studies were primarily conducted in the UK, USA, Canada, and Europe. South Asian migrants had inadequate oral health knowledge, attitudes, and practices-influenced by culture, social norms, and religiosity. In the absence of symptoms, preventive oral hygiene practices were limited. Barriers to access varied with country of origin; from lack of trust in dentists and treatment cost in studies with India as the country of origin, to religiosity, among poorer nations such as Bangladesh. Fewer studies focused on recent arrivals from Bhutan or the Maldives. Culturally and socially appropriate strategies must be developed to target oral health issues and a "one-size" fits all approach will be ineffective in addressing the needs of South Asian migrants.

Relationship between oral clinical conditions and daily performances among young adults in India - a cross sectional study.

Objective of the present study was to investigate relationship between oral health-related quality of life using Oral Impacts on Daily Performances (OIDP) scale and specific clinical dental measures. A cross sectional descriptive survey was conducted among 800 students. Oral health status and impacts were assessed using WHO guidelines and OIDP index respectively. Chi square test and multiple logistic regressions were employed for statistical analysis. Participants with caries were significantly (p⩽0.05) more likely to have an impact on cleaning (OR=2.487) and sleeping and relaxing (OR=8.996). Similarly participants with oral mucosal conditions were more likely to have an impact on eating (OR=3.97), cleaning (OR=2.966) and physical activities (OR=11.190). Dental Aesthetic Index (DAI) impacted on cleaning (OR=2.134), emotional stability (OR=3.957) and social contact (OR=3.21). OIDP Index showed acceptable psychometric properties in the context of an oral health survey. Subjects presented a strong and consistent relationship between dental status and perceived impacts.

Perceived barriers to the provision of preventive care among dentists of Udaipur, India.

AIM: To investigate the practice-, patient- and dentist related barriers to the provision of preventive dental care as perceived by dentists of Udaipur city, Rajasthan, India. SETTINGS AND DESIGN: - A cross sectional descriptive survey was conducted among 120 dentists of Udaipur city, Rajasthan. MATERIAL AND METHODS: Mean Content Validity Ratio (CVR) was calculated as 0.87 based on the opinions expressed by a panel of total six academicians. Cronbach's coefficient was found to be 0.88, which showed a high internal reliability of the questionnaire. The questionnaire consisted of demographic questions and 12 specific research questions. STATISTICAL ANALYSIS USED: - Student's t-test and ANOVA test were applied for the statistical evaluation of means. Level of significance was set at 0.05. RESULTS: The barriers correlated strongly with each other (0.60 to 0.85). A significant gender difference was observed in mean sums of scores of practice and patient related barriers. Practice, dentist and patient related barriers for very much hindrance were reported by 8 to 13%, 5 to19% and 0 to 29% of the dentists respectively. A significant difference was observed among mean of sum scores of practice and patient related barriers with age and experience. Qualification was significantly related to practice related barriers. CONCLUSIONS: Perception of dentists showed that patient related barriers were found to be the foremost to the provision of preventive care. Also, dentist's attitude towards health promotion and disease prevention needs a radical transformation. Key words:Dental care, dentists, patients, perception.

Cariogram Model in Assessment of Dental Caries among Mentally Challenged and Visually Impaired Individuals of Udaipur, India.

OBJECTIVES: To assess the caries risk and contribution of diet, bacteria, circumstances and susceptibility sectors among special groups in comparison to the normal group of Udaipur using the Cariogram model. MATERIALS AND METHODS: A Cariogram model was used to identify risk factors among 160 subjects (40 mentally challenged, 60 visually impaired and 60 normal healthy individuals) aged 7-36 years. Statistical analysis was done using Chi-square/ Fischer's Exact followed by Marascuilo procedure and Stepwise multiple linear regression. RESULTS: Compared to the normal group (74%), mentally challenged (33%) and visually impaired (41%) groups showed less chances of avoiding future caries. Group (R= 0.660) was found to be strongest predictor for caries risk. Susceptibility sector contributed 61% for caries risk in all the groups. CONCLUSION: The caries risk was high among special groups compared to normal group. Susceptibility sector illustrated the highest contribution for caries risk in all groups.
