Brief Summary:
A study aims to assess the most effective preventive interventions to address the widespread issue of dental caries affecting an estimated 2 billion people in permanent teeth and over 500 million children in primary teeth globally Notably in Pakistan over 90 of caries-affected teeth are untreated Despite schools being a platform for public health initiatives there is limited evidence on oral health promotion in low and middle-income countries This study compares different preventive strategies effectiveness and cost-efficiency for caries prevention in schoolchildren
The randomized controlled trial will occur in Naval Schools of Karachi under the Pakistan Navy Educational Trust PNET over one year including intervention and follow-up periods The interventions include a combination of fluoride toothpaste dietary counselling and fissure sealant application A multi-stage sampling method will select schools and classes while convenience random sampling will select 180 children for the study A single-blind trial will be conducted with the data analyst unaware of the intervention groups
Participants will be divided into three groups Group 1 Control will use fluoride toothpaste and be instructed to brush twice daily Group 2 Intervention-1 will receive 14500 ppm fluoride toothpaste and oral health education Group 3 Intervention-2 will include the treatments from Group 2 plus fissure sealants on the first permanent molars Parents in Groups 2 and 3 will receive a standardized advice sheet to reinforce oral hygiene practices at home
The study will collect baseline demographic data including age gender socioeconomic status family education existing oral hygiene practices dental knowledge and dentition status Oral examinations will be conducted according to international standards Statistical analysis will employ Chi-Square ANOVA and logistic regression tests with a significance level set at 005
The study aims to determine the most effective preventive strategy by comparing the reduction in dental caries incidence across the groups The findings will guide recommendations for implementing the most effective intervention on a larger scale in schools with the goal of reducing the burden of dental caries in children

Detailed Description:
Ethical Approval approved by the BUHSC ethical committee School administrations will be approached for permission Consent forms will be sent to the parents of the children before the data collection visit The data collection team comprised of 06 members will visit the selected schools A signed consent form will be taken and verbal consent will be obtained from the children as well The children fulfilling the inclusion criteria will be sequenced as a list Randomization will be done through SNOSE - a sequential number of opaque sealed envelopes will be done and the students will then be allocated in 3 groups
PI Co-PI and 05 team members will conduct oral examinations in the selected schoolyard or inside a classroom following the standard international guidelines WHO 2013 In addition the baseline demographic data will also be collected comprising of age gender socioeconomic status SES family education and existing oral hygiene practices dental knowledge and dentition status by the parents and participants Group 1 Control will be given fluoride toothpaste containing 1450 ppm Fluoride and will be asked to brush at least twice daily with a pea-sized amount of toothpaste using the modified bass technique This will be considered as control Some intervention in the control group will also address the ethical issues Parents will be guided for the tooth brushing
Group 2 Intervention -1 will be given fluoride toothpaste containing 1450 ppm Fluoride and will be asked to brush at least twice daily with a pea-sized amount of toothpaste and oral health education A modified bass technique for tooth brushing will be used Oral health education through audio-visual aids pamphlets and live demonstrations on study models will cover proper tooth brushing techniques the use of a good toothbrush and healthy eating habits including special emphasis on proteins and dairy products and alternate use of sugars in daily routine Eg soft drinks that are high in sugar can be replaced with drinking milk and water
Group 3 Intervention -1 will be given fissure sealants on 1st permanent molar along with the strategy given to Group 2 Fissure sealing compounds Glass ionomer will be used on school children who will qualify for inclusion criteria Mobile Dental Unit and fissure sealant kit will be taken to the site and children will be provided fissure sealant in their setting
In the intervention group 2 and 3 parents will also be given an Evidence-Based standardized parental advice sheet to reinforce instructions at home
The saliva of school children will be collected by spitting in a test tube For children over the age of 6 saliva can be collected using the expectoration or spit method In this process the child is instructed to keep their mouth closed for three minutes without swallowing allowing saliva to accumulate before spitting it into a collection tube However some children may struggle with this technique due to the challenge of not swallowing for an extended period An alternative method is the drainage technique Here the child is first asked to swallow their saliva to stimulate the production of more saliva Then with their lips slightly parted the saliva is allowed to drain directly into the collection tube The samples will be taken to the laboratory within 02 hours of collection Streptococcus mutans count will be conducted on collected saliva at the first visit to provide an initial bacterial count as baseline data before intervention and after six-month and 12-month bacterial count after the intervention The primary medium used to identify streptococci is Mitis-Salivarius agar or its variant with bacitracin MSB Additionally salivas pH flow rate and buffering capacity will be measured in the lab The first visit will be followed by six months and 12 months respectively A preliminary pilot study will be undertaken with a limited sample size to assess the practicality of the interventions and enhance the process of collecting data
The data collected through the questionnaire and log book filled by parents at home will be computerized followed by converting it into the appropriate SPSS files The outcome variables for assessing dental caries will be measured by ICDAS The ICDAS is a two-digit coding method One for caries and the other for sealant and restorations In this research only the caries coding method will be used For caries the method ranges from sound teeth code 0 through enamel caries lesions codes 1-3 to carious lesions in dentine codes 4-6 For sealant and restoration the method ranges from 0 to 8 as follows 0 Sound 1 Sealant partial 2 Sealant full 3 Tooth-coloured restoration 4 Amalgam restoration 5 Stainless steel crown 6 Porcelain or gold or Porcelain-Fused-to-Metal PFM crown or veneer 7 Lost or broken restoration 8 Temporary restoration will not be used Caries Codes 0 sound tooth surface A first visual change in enamel B distinct visual change in enamel 3 enamel breakdown no dentine visible 4 dentinal shadow not cavitated into dentine 5 distinct cavity with visible dentine 6 extensive distinct cavity with visible dentine Missing Teeth 97 extracted due to caries 98 missing for other reasons 99 un-erupted
Salivary indicators ie salivary flux - 03-04 mlmin Salivary pH - 5-58 high acidity 60-66 moderate acidity 68-78 normal salivary pH Salivary buffer capacity - 3-30 mg100 ml Salivary Mutans count - 105 CFUml saliva or 105 CFUml saliva The study will use the CONSORT checklist for reporting the randomized control trial
