RESUMEN
INTRODUCTION: Hypertension and diabetes are modifiable risk factors for dementia. We aimed to assess rural-urban disparities in the diagnosis and treatment of these conditions among aging Indians. METHODS: Participants (n = 6316) were from two parallel, prospective aging cohorts in rural and urban India. Using self-report and clinical/biochemical assessments, we subdivided participants with diabetes and hypertension into undiagnosed and untreated groups. Logistic regression and Fairlie decomposition analysis were the statistical methods utilized. RESULTS: There was a significant rural-urban disparity in undiagnosed hypertension (25.14%), untreated hypertension (11.75%), undiagnosed diabetes (16.94%), and untreated diabetes (11.62%). Further, sociodemographic and lifestyle factors, such as age and tobacco use were the common contributors to the disparities in both undiagnosed hypertension and undiagnosed diabetes, whereas education and body mass index (BMI) were significant contributors to the disparity in untreated hypertension. DISCUSSION: Rural Indians face significant healthcare disadvantages as compared to their urban counterparts, which prompts the urgent need for strategies for equitable healthcare.

Neurodegenerative diseases are progressive disorders of the nervous system primarily affecting the loss of neuronal cells present in the brain. Although most neurodegenerative cases are sporadic, some familial genes are found to be involved in the neurodegenerative diseases. The extensively studied parkin and pink1 gene products are known to be involved in the removal of damaged mitochondria via autophagy (mitophagy), a quality control process. If the function of any of these genes is somehow disrupted, accumulation of damaged mitochondria occurs in the forms of protein aggregates in the cytoplasm, leading to formation of the Lewy-bodies. Autophagy is an important catabolic process where the endosomal Rab proteins are seen to be involved. Rab11, an endosomal recycling protein, serves as an ATG9A carrier that helps in autophagosome formation and maturation. Earlier studies have reported that loss of Rab11 prevents the fusion of autophagosomes with the late endosomes hampering the autophagy pathway resulting in apoptosis of cells. In this study, we have emphasized on the importance and functional role of Rab11 in the molecular pathway of Parkin/Pink1 in Parkinson's disease.

Parkinson's disease (PD) is a common neurodegenerative disorder caused by the loss of dopaminergic neurons in the substantia nigra. The pathophysiology of this disease is the formation of the Lewy body, mostly consisting of alpha-synuclein and dysfunctional mitochondria. There are two common PD-associated genes, Pink1 (encoding a mitochondrial ser/thr kinase) and Parkin (encoding cytosolic E3-ubiquitin ligase), involved in the mitochondrial quality control pathway. They assist in removing damaged mitochondria via selective autophagy (mitophagy) which if unchecked, results in the formation of protein aggregates in the cytoplasm. The role of Rab11, a small Ras-like GTPase associated with recycling endosomes, in PD is still unclear. In the present study, we used the PD model of Drosophila melanogaster and found that Rab11 has a crucial role in the regulation of mitochondrial quality control and endo-lysosomal pathways in association with Parkin and Pink1 and Rab11 acting downstream of Parkin. Additionally, overexpression of Rab11 in parkin mutant rescued the mitochondrial impairment, suggesting the therapeutic potential of Rab11 in PD pathogenesis.

The development of low arsenic-accumulating varieties for the contaminated areas is one of the best options for reducing the dietary exposure of arsenic to human population through rice. In this study, grain-arsenic content in one hundred genotypes revealed a large variation ranging from 0.05 mg/kg to 0.49 mg/kg. Compared to high accumulating variety, Shatabdi, 6-8 times the transcript upregulation of Arsenic sequestering ATP binding cassette C1 type gene (ABCC1), was observed in first internode of low accumulating variety Gobindabhog when 5 mg/kg of arsenite was present in soil. A comparison of the genomic sequence of OsABCC1 identified 8 SNPs between the two genotypes; 5 in introns and 3 silent mutations in exons. We identified a PCR based co-dominant marker targeting an SNP (T/G) between the two genotypes, which clearly distinguished 100 genotypes into low (mean 0.14 mg/kg) and high (mean 0.35 mg/kg) accumulating groups. All aromatic genotypes, either long or small grain, carry the Gobindabhog-type ABCC1 allele and are low accumulators of arsenic. Gobindabhog allele carrying 62 RILs and NILs showed almost 40-50% less As-accumulation in grains relative to 84 RILs and NILs carrying Shatabdi type ABCC1-allele. The marker will be useful in introgression of low accumulating allele of OsABCC1 into high yielding photoperiod insensitive varietal backgrounds more easily and accurately.

Aim: The present study was conducted with an aim to assess the antimicrobial activity of Ocimum sanctum (tulsi) extract on Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis.Materials and methods: Tulsi extract with ethanol was prepared using cold extraction method in the present in vitro study. Various concentrations (2, 4, 6, and 8%) were then obtained by dilution with dimethylformamide. A 0.2% chlorhexidine served as the positive control, whereas the negative control was dimeth-ylformamide. Zones of inhibition were measured, each for A. actinomycetemcomitans and P. gingivalis. For comparison within the group and between the study groups, one-way analysis of variance (ANOVA) and Tukey's post hoc tests were used. A statistical significance level of p < 0.05 was established. Results: The 8% concentration of the tulsi extract showed maximum zone of inhibition against A. actinomycetemcomitans and P. gingivalis (40.10 ± 0.90, 33.79 ± 1.82 mm), followed by the 6, 4, and 2% concentrations. The 0.2% chlorhexidine, which was the positive control, had 39.80 ± 1.24 and 32.28 ± 1.28 mm zones of inhibition; dimethylformamide showed 13.55 ± 1.92 and 10.21 ± 2.16 mm zones of inhibition against both the microorganisms. The ANOVA showed highly statistically significant (p < 0.0001) results between and within the groups. The antimicrobial activity of tulsi extract at 6 and 8% concentrations, and 0.2% chlorhexidine against A. actinomycetemcomitans showed statistically significant differences between the groups. The concentration of tulsi extract at 8 and 0.2% chlorhexidine on P. gingivalis showed statistically significant differences between the groups. Conclusion: It was concluded that 8% concentration of O. sanctum (tulsi) extract showed the maximum antimicrobial activity against A. actinomycetemcomitans and P. gingivalis. It is thus recommended that this may be useful as an adjunc-tive to mechanical therapy in the prevention and treatment of periodontal diseases. Clinical significance:O. sanctum (tulsi) is a herb that is abundantly available, easily accessible, economically feasible, and culturally acceptable. Therefore, it is very useful in the management of oral diseases and also for overcoming many barriers that exist for the utilization of dental services, such as affordability, accessibility, availability, and acceptability. Keywords:Aggregatibacter actinomycetemcomitans, Antimicrobial, Ocimum sanctum, Porphyromonas gingivalis.

Sesame is an important ancient oilseed crop of high medicinal value. In the present study, 37 characters including both quantitative and qualitative traits of sixty genotypes were characterized following IPGRI morphological descriptors for sesame. Multivariate analysis was computed to distinguish the varieties into different groups. Though thirty six microsatellite markers including genomic and Est-SSR markers were initially selected, but, finally, the accessions were genotyped by eight polymorphic primers. Altogether, 27 alleles were detected among the 60 genotypes, with an average of 3.37 alleles per locus. The number of alleles ranged from 2 to 6 alleles. From data of microsatellite markers, dissimilarity coefficients between varieties were computed following Jaccard's coefficient method. Principal co-ordinate analysis was used to represent the varieties in bi-directional space. Dendrogram was constructed using NJ method based on dissimilarity matrix. Cluster analysis based on morphological and molecular marker classified sesame genotypes into two major groups. Mantel test showed an insignificant correlation between phenotypic and molecular marker information. The genotypes belonging to the same geographical area did not always occupy the same cluster. The results confirmed that both genetic and phenotypic diversity in a combined way could efficiently evaluate the variation present in different sesame accessions in any breeding program.
RESUMEN
Introduction: Sleep is known to be involved in cognitive processes, such as memory encoding and consolidation, and poor sleep is a potential risk factor for dementia. This study aims to investigate the effect of sleep quality on memory functions among middle-aged and older adults from a rural Indian population. Methods: Participants were non-demented, rural Indians (≥45 years) from an ongoing, prospective, aging cohort study, namely Srinivaspura Aging, NeuroSenescence, and COGnition (SANSCOG) study. Cross-sectional (baseline) data on seven sleep dimensions was obtained using the Pittsburgh Sleep Quality Index (PSQI). Memory functions were assessed using immediate recall, delayed recall, name-face association, and semantic association from a culturally validated, computerized, neurocognitive test battery. Linear regression models, unadjusted and adjusted for cognitive status, age, sex, and depression were used to analyze the association between each sleep dimension and the memory tests. Results: A total of 1195 participants, with a mean age of 57.10 years, were included. Out of the seven sleep dimensions of the PSQI, only two dimensions, namely sleep duration and sleep efficiency, were significantly associated with memory functions. In the fully adjusted model, shorter sleep duration was significantly associated with poorer performance in delayed recall, and lesser sleep efficiency was significantly associated with poorer delayed recall and semantic association performance. Conclusions: Specific sleep characteristics appear to influence memory functions in aging Indians well before the onset of dementia. In the backdrop of the non-availability of a definitive treatment for dementia, promptly identifying and addressing these problems could be an effective, community-level strategy for preventing dementia.
RESUMEN
Dysfunctional mitophagy contributes to Parkinson's disease (PD) by affecting dopamine-producing neurons. Mutations in parkin and pink1 genes, linked to familial PD, impede the removal of damaged mitochondria. Previous studies suggested Rab11's involvement in mitophagy alongside Parkin and Pink1. Additionally, mitochondria-endoplasmic reticulum contact sites (MERCS) regulate cellular functions, including mitochondrial quality control and calcium regulation. Our study explored whether activating mitophagy triggers the unfolded protein response and ER stress pathway in SH-SY5Y human cells. We induced a PD-like state by exposing undifferentiated SH-SY5Y cells to rotenone, an established PD-inducing agent. This led to reduced Rab11 and PERK- expression while increasing ATP5a, a mitochondrial marker, when Rab11 was overexpressed. Our findings suggest that enhancing endosomal trafficking can mitigate ER stress by regulating mitochondria, rescuing cells from apoptosis. Furthermore, we assessed the therapeutic potential of Rab11, both alone and in combination with L-Dopa, in a Drosophila PD model. In summary, our research underscores the role of mitophagy dysfunction in PD pathogenesis, highlighting Rab11's importance in alleviating ER stress and preserving mitochondrial function. It also provides insights into potential PD management strategies, including the synergistic use of Rab11 and L-Dopa.

Background: Metabolic syndrome (MetS), characterized by elevated blood pressure, high blood glucose, excess abdominal fat, and abnormal cholesterol or triglyceride levels, significantly increases the risk of various non-communicable diseases. This study focuses on understanding the sex-specific association between Apolipoprotein E (APOE) polymorphism and MetS among middle-aged and older adults in rural southern India. Methods: This cross-sectional study utilized data from the Centre for Brain Research-Srinivaspura Aging, Neuro Senescence, and COGnition (CBR-SANSCOG) study. Participants (n = 3741) underwent comprehensive clinical assessments and blood investigations, including APOE genotyping. MetS was defined using the National Cholesterol Education Program - Adult Treatment Panel III (NCEP ATP III) and the Consensus criteria. Statistical analyses, including chi-square tests, ANCOVA, and logistic regression, were conducted to explore the association of APOE genotype with MetS and its components, stratified by sex. Results: Females carrying the APOE E4 allele had 1.31-fold increased odds of MetS (95 % CI: 1.02,1.69, p = 0.035) according to the NCEP ATP III criteria but not when the Consensus criteria were applied. The study also noted sex-specific differences in the association of APOE with various MetS components, including lipid levels and waist circumference. Discussion: Our findings reveal a sex-specific association between the APOE E4 allele and MetS, with only females having an increased risk. This study contributes to the understanding of the genetic underpinnings of MetS and highlights the importance of considering sex-specific differences in MetS research and its prevention strategies. This study underscores the complexity of MetS etiology and emphasizes the need for further research to elucidate the role of genetic, environmental, and lifestyle factors in its progression, particularly in sex-specific contexts.
RESUMEN
Objectives: Several genetic factors have been associated with cognitive decline in aging. Apolipoprotein E (ApoE) ε4 has been widely studied in the risk for pathological cognitive decline, including dementia. However, the association between ApoE ε4 and cognitive functioning in the healthy aging Indian population has been understudied, and the results are ambiguous. Materials and Methods: This study aims to examine the role of the ApoE genotype with attentional function in aging adults (≥45 years) in a rural Indian population. Cross-sectional (baseline) data (n = 2100) was utilized from an ongoing longitudinal cohort study on aging (Srinivaspura Aging, Neurosenescence, and Cognition study). Participants hailed from villages of Srinivaspura in Karnataka, southern India. Participants were categorized based on ApoE-ε4 status into three categories: No ε4, heterozygous ε4, and homozygous ε4. Attentional function was assessed using the auditory and visual attention subtests from a computerized neurocognitive test battery. Linear regression was performed adjusting for age, gender, and education. Results: In model 1 (unadjusted), we did not find an association between ApoE and attention function. In the partially adjusted model 2 (adjusting for age), ApoE ε4 with age was significantly associated with the attention function. Further, with increasing age, there was a decline in attention among homozygous ε4 individuals. Model 3 (model 2 + gender) found that ApoE ε4, age, and gender explained a significant variance in attention function. In addition, with increasing age, males had poor attention in the homozygous as compared to heterozygous group. Model 4 (model 3+ education) explained a significant variance in attention and also revealed that with increasing age, attention declined in the illiterate and low literacy groups in both homozygous and heterozygous groups among both genders. Conclusion: Although ApoE ε4 alone was not associated, it interacted with age, gender, and education to affect attention function in this rural Indian population. Longitudinal cognitive monitoring will yield insights into understanding whether the ApoE ε4 genotype influences the rate of cognitive decline in this rural, aging population.
RESUMEN
Background: This study examines the association between apolipoprotein E (APOE) genotypes and metabolic syndrome (MetS) in an older urban population in South India, as part of the Tata Longitudinal Study on Aging. Methods: A total of 618 participants aged 45 and above were analyzed cross-sectionally for the association between APOE carrier status and MetS (based on both NCEP ATP III and Consensus criteria). Results: Despite the high prevalence of MetS observed in this cohort (51.62 % by NCEP-ATP III and 61.33 % by Consensus criteria), multivariable logistic regression revealed no significant association between APOE genotypes and MetS under both criteria. However, specific associations were noted in age and sex-stratified analyses; notably, E2 carriers under 60 showed 0.42-fold decreased odds (95%CI:0.20,0.89, p-value-0.023) for an increased waist circumference, and E4 carriers above 60 were at 1.85 times increased odds (95 % CI:1.04,3.28, p-value<0.05) for decreased HDL. Conclusion: These findings suggest that while APOE genotypes influence certain metabolic parameters, their impact on MetS may be limited in this urban setting, possibly overshadowed by environmental factors and lifestyle influences, which was highlighted by the differences seen in its sister rural cohort.
RESUMEN
Oral cancer became a very common condition. WHO estimates that there are 4 cases of lip and oral cavity cancer for every 100,000 people worldwide. The early diagnosis of cancers is currently a top focus in the health sector. Recent systematic reviews and meta-analyses have identified promising biomarkers for early detection in several original research investigations. However, it is still unclear the quality of these evidence and which biomarker performs the best in terms of early detection. Therefore, the objective was, to map the methodological and reporting quality of available oral squamous cell carcinoma (OSCC) or head/neck squamous cell carcinoma (HNSCC) systematic reviews and meta-analysis. Secondly, to evaluate diagnostic accuracy of salivary biomarkers for common craniofacial cancers and to compare the diagnostic value of different salivary biomarkers. PubMed, Scopus, Web of Science, Embase and Cochrane Library electronic databases were used to map the methodological and reporting quality of the systematic reviews and meta-analysis conducted on the HNSCC, OSCC using the AMSTAR-2 checklist. The inclusion criteria were systematic reviews and meta-analysis published in the topic of HNSCC and OSCC biomarkers. Exclusion criteria were no animal studies; original primary studies, due to limitation of competency in other languages articles with language other than English were excluded. The sensitivity and specificity were calculated for salivary biomarkers and ranked according to network meta-analysis principles. A total of N = 5893 patients were included from four meta-analysis studies. All together, these included n = 37 primary studies. n = 94 biomarkers were pooled from these four meta-analyses and categorised into the stages at which they were detected (I-IV). In OSCC, Chemerin and MMP-9 displayed the highest sensitivity, registering 0.94 (95% CI 0.78, 1.00) and a balanced accuracy of 0.93. Phytosphingosine closely followed, with a sensitivity of 0.91 (95% CI 0.68, 0.99) and a balanced accuracy of 0.87. For HNSCC, the top three biomarkers are Actin, IL-1ß Singleplex, and IL-8 ELISA. Actin leads with a sensitivity of 0.91 (95% CI 0.68-0.99), a specificity of 0.67, and an overall accuracy of 0.79. Subsequently, IL-1ß Singleplex exhibits a sensitivity of 0.62 (95% CI 0.30-0.88), a specificity of 0.89, and an accuracy of 0.75, followed by IL-8 ELISA with a sensitivity of 0.81 (95% CI 0.54-0.97), a specificity of 0.59, and an accuracy of 0.70. In conclusion, there was highest sensitivity for MMP-9 and chemerin salivary biomarkers. There is need of further more studies to identify biomarkers for HNSCC and OSCC.
RESUMEN
Objectives: Recent studies have shown that multilingualism may play an important role in enhancing cognitive health. The process of language acquisition constitutes a form of natural brain training, which in turn is hypothesized to increase neuroplasticity and hence, maintains the cognitive reserve. The study aimed to analyze the relationship between the number of languages known to an individual and its effect on cognitive functioning in both healthy and cognitively impaired study participants. Materials and Methods: This study utilized cross-sectional (baseline) data from Srinivasapura Aging, Neuro Senescence and COGnition study, which is an ongoing community-based, longitudinal aging cohort study conducted in a rural setting in southern India. A total of 3725 participants were considered for the study. The participants were separated into two groups, namely, monolinguals (participants knowing one language) and multilingual (participants knowing more than one language). The cognitive performance of the participants was assessed using the Clinical Dementia Rating (CDR) Scale. In addition, bivariate analyses and binary logistic regression analyses were carried out. Results: The result of CDR scores with respect to language category shows that, among the monolingual participants, 86.5% were healthy individuals and 13.5% were with mild cognitive impairment (MCI). Similarly, among the multilingual, 94.3% were healthy and 5.7% were with MCI. The odds ratio value derived from logistic regression (0.69 95% CI (0.5-0.9)) that an individual has a higher chance of developing cognitive impairment if he/she is a monolingual. Conclusion: This study highlights that knowing more than one language might have a profound positive impact on cognitive health, thereby reducing the likelihood of developing cognitive decline.
RESUMEN
Mutation in parkin and pink1 is associated with Parkinson's disease (PD), the most common movement disorder characterized by muscular dysfunction. In a previous study, we observed that Rab11, a member of the small Ras GTPase family, regulates the mitophagy pathway mediated by Parkin and Pink1 in the larval brain of the Drosophila PD model. Here, we describe that the expression and interaction of Rab11 in the PD model of Drosophila is highly conserved across different phylogenic groups. The loss of function in these two proteins, i.e., Parkin and Pink1, leads to mitochondrial aggregation. Rab11 loss of function results in muscle degeneration, movement disorder and synaptic morphological defects. We report that overexpression of Rab11 in park13 heterozygous mutant improves muscle and synaptic organization by reducing mitochondrial aggregations and improving cytoskeleton structural organization. We also show the functional relationship between Rab11 and Brp, apre-synaptic scaffolding protein, required for synaptic neurotransmission. Using park13 heterozygous mutant and pink1RNAi lines, we showed reduced expression of Brp and consequently, there were synaptic dysfunctions including impaired synaptic transmission, decreased bouton size, increase in the bouton numbers, and the length of axonal innervations at the larval neuromuscular junction (NMJ). These synaptic alterations were rescued with the over-expression of Rab11 in the park13 heterozygous mutants. In conclusion, this work emphasizes the importance of Rab11 in rescuing muscle degeneration, movement dysfunction and synaptic morphology by preserving mitochondrial function in the PD model of Drosophila.

Background: Out of pocket and catastrophic healthcare expenditures are leading households to financial hardships in India. The covid-19 pandemic has further added up in the loss of jobs, savings, and lives. The inclusion of covid-19 treatments in health insurance schemes like Ayushman Bharat Arogya Karnataka by the Government has helped families from financial hardships and catastrophic healthcare expenditures. Objectives: To estimate the utilization of the Ayushman Bharat insurance scheme among covid-19 positive patients in a tertiary care hospital, Dakshina Kannada District. Methodology: It was a record-based, cross-sectional study. The study was conducted by collecting data from the hospital medical records department by taking prior permission at a Tertiary Care Hospital of Dakshina Kannada District, Karnataka. The data was collected and entered into an excel sheet, analyzed, and presented in percentage in the tabular form. Results: In the present study total 1367 covid-19 positive cases were admitted. Majority of the patients were from Karnataka accounting for 93.92%. The eligible subjects for ABArK were 906 (66.27%), Out of which 714 (78.8%) had utilized the scheme. Among the 714 patients who utilized the ABArK scheme 443 (62.04%) were men and 271 (37.95%) were women. Conclusion: The utilization of this scheme requires further improvement by creating awareness activities among general public. This helps in reducing the out-of-pocket expenditure and burden in accessing the healthcare facility.
RESUMEN
The aim of this review was to answer the following PICO question: "Do TMJ kinematic parameters (intervention and comparison) show efficacy for assessment of mandibular function (Outcome) both in asymptomatic and TMD subjects? (Population)". PubMed, Scopus, Web of Science, Embase, Central databases were searched. The inclusion criteria were (1) performed on human, (2) English only, (3) on healthy, symptomatic or surgically altered TMJ, (4) measured dynamic kinematics of mandible or TMJ (5) with six degrees of freedom. To assess the Risk of Bias, the Joanna Briggs Institute tool for non-randomised clinical studies was employed. A pairwise meta-analysis was carried out using STATA v.17.0 (Stata). The heterogeneity was estimated using the Q value and the inconsistency index. Ninety-two articles were included in qualitative synthesis, nine studies in quantitative synthesis. The condylar inclination was significantly increased in female (effect size 0.03°, 95% CI: -0.06, 0.12, p = 0.00). Maximum mouth opening (MMO) was increased significantly in female population in comparison with males (effect size 0.65 millimetres (0.36, 1.66). Incisor displacement at MMO showed higher values for control groups compared with TMD subjects (overall effect size 0.16 millimetres (-0.37, 0.69). Evidence is still needed, considering the great variety of devices and parameters used for arthrokinematics. The present study suggests standardising outcomes, design, and population of the future studies in order to obtain more reliable and repeatable values.
RESUMEN
Improving spikelet number without limiting panicle number is an important strategy to increase rice productivity. In this study, a spikelet number enhancing SPIKE-allele was identified from the aus subtype indica rice, cv. Bhutmuri, which has an identical japonica like corresponding sequence including a retrotransposon sequence, usually absent in indica genotypes, like IR64. An allele-specific singletube PCR-based codominant marker targeting an A/G single-nucleotide polymorphism (SNP) at the 3'UTR was identified for easier genotyping. The yield enhancing ability of the Bhutmuri-SPIKE allele carrying RILs and NILs over IR64-SPIKE allele carrying alleles was due to increased number of filled grains/panicle. More than three times higher abundance of SPIKE transcripts was observed in Bhutmuri and NILs carrying this allele compared with IR64 and its allele carrying NILs. Higher rate of photosynthesis at more than 900 µmolm-2s-1 light intensity and more than six small vascular bundles between the two large vascular bundles in the flag leaves of Bhutmuri and its allele carrying NILs were also observed. The identified SPIKE allele and the marker associated with it will be useful for increasing the productivity of rice by marker-assisted breeding.

BACKGROUND: Newborn hospitalized in the neonatal intensive care unit (NICU) raises a mother's risk of reduced health-related quality of life (QoL). We explored the contributors inducing stress among mothers related to NICU. METHODOLOGY: One hundred thirty-five mothers, whose newborn has completed 48 hours of NICU stay, were interviewed using parental stress scale: neonatal intensive care unit and SF-36 health survey questionnaire for further assessment. RESULTS: The look and behavior of the baby were predominant contributor to the decreased QoL among mothers (p= <.001). A moderate negative association between parental stresses related to the NICU environment and their QoL ρ = -.467 was observed. CONCLUSION: It is required to look back at the interiors of the Intensive Care Unit (ICU), the duration provided for the mother and child's physical bonding, the unnecessary noise of the alarms and the jungle of wires around the baby to optimize the QoL of mothers. The further policy requires focusing on building a relation of the mother and child, especially when a child needs supportive care.

BACKGROUND: The molar incisor hypomineralization (MIH) is defined as a qualitative defect of the enamel characterised by the progressive and simultaneous hypomineralization of the enamel structure of the first permanent molars which is of systemic origin, which may be associated frequently with incisors. Although the reported prevalence of MIH ranges from 2.4% to 40.2% worldwide, very little data is available from India. AIM: To determine the prevalence of molar incisor hypomineralization among school children aged 9 to 12 years in virajpet, Karnataka. METHODS: This cross-sectional descriptive study consisted of 1600 school children aged 9-12 years selected by stratified cluster sampling procedure. The European Academy of Pediatric Dentistry criteria were followed for MIH diagnosis. Chi-square test was used to analyse the categorical data. P ≤ 0.05 was considered for statistical significance. RESULTS: The prevalence of MIH is 13.12% with no gender predilection. Ten-year-old children showed the highest prevalence (15%) among all the age group. Majority of children with MIH (70.2%) have lesions in both molars and incisors with demarcated opacities and atypical restorations being the most frequent defect type. CONCLUSION: Prevalence of MIH was 13.12% in the 9-12-year child population in Virajpet. There is a need for a proper planned preventive and restorative program about the increasing prevalence of MIH.
