Brief Summary:
Fluoride varnish application is universally accepted as a dental caries prevention method This study was aimed in assessment of clinical outcome and cost effectiveness in using that method in Sri Lankan school children
Detailed Description:
Background Dental caries remains a significant public health problem with multiple factors such as socioeconomic dietary and microbiological playing a major role as risk factors in initiation and continuation of the disease It is considered the most common cause of toothache and hospital admissions in young children Dental caries in school children not only causes pain but also affects school attendance parents work hours childrens ability to eat play rest and sleep Therefore dental caries when present significantly reduces the health related quality of life of a child
Improving oral health has been considered as an objective in preventive dental care for children Therefore the measures taken to prevent dental caries should include bacterial bio film control dietary counseling use of fluoride products such as toothpastes mouth rinses varnishes gels and foams and Casein phosphopeptide CPP - amorphous calcium phosphate ACP cream and gums and placing resin-basedglass ionomer pit and fissure sealants Professional fluoride varnish application has become popular among all methods as variety of studies has discussed its effect in reducing dental caries
Fluoride varnish use in the US has increased markedly since it was approved by the FDA in 1994 Fluoride varnishs effectiveness in caries prevention ease of application and safety give it an advantage over other types of topical fluoride treatments such as gels and rinses or other caries management methods As a result it is regarded as one of the superior topical fluoride agents for young children Fluoride varnish also prolongs the contact time between fluoride and tooth surface to reduce caries Its active ingredient is usually 5 sodium fluoride or 22600 ppm fluoride It also has recently gained much attention in dentistry because the risk of dental fluorosis is found to be minimalThe simplicity of its application makes it very suitable and practical for use in different places and groups
Justification Despite the availability of free health dental service in Sri Lanka the prevalence and severity of dental caries among six and seven years old school children stand at a very high level according to the results of national oral health survey as 78 8384 764 9495 and 655 20022003 whereas the dmft is 44 41 and 369 The simplicity of fluoride varnish application makes it very suitable and practical for use in dental clinics and outreach dental services especially in young children and in other special needs groups
Up to date to our knowledge there was no other study carried out on cost effectiveness of fluoride varnish application on teeth in Sri Lankan population Therefore the results of the study will be beneficial in implementation and identification of advantages of fluoride varnish application on teeth in young children
Aim The main objective of this study was to evaluate the cost effectiveness of six monthly application of sodium fluoride varnish in prevention of dental caries in deciduous teeth permanent incisors and molars in children between six and seven years in Sri Lanka
The specific objective is
1 To find out the association between dental caries and the social status of the child eg mothers education fathers education monthly family income etc
Methods Study Type Interventional This was a double-blind randomized controlled trial A sample of school children 6-7 years were randomized into varnish and control groups All the children received routine caries preventive measures of oral hygiene instructions dietary advice and professional cleaning Children in fluoride varnish application group received fluoride varnish professionally applied after prophylaxis every 6 months combined with counseling on maintenance of oral hygiene and diet for a period of 2 years Clinical examinations of all children were performed at the beginning of the study and 1 year and 2 years later All the caries at the dentinal level of both groups were stabilized with temporary restorations at the beginning For evaluation and comparison all the collected data was subjected to statistical analysis Both varnish and control groups were subjected to use of fluoride tooth paste of 1000ppm The control group was subjected to counseling on maintenance of oral hygiene and diet During this period the team visited each school four times at six months interval for recruitment dental examinations and fluoride varnish applications Recruited children were randomly assigned to either a treatment 5 Sodium Fluoride varnish or a control group Trained interviewers collected data on oral health habits and sociodemographic characteristics of the children Information on the childs diet was collected through a 4-day food frequency diary Caries examinations were conducted using the International Caries Detection and Assessment System ICDAS The cost for the dental teams school visits cost involved in the treatment of dental caries throughout the course of the study in both groups were evaluated and compared at the end of the study
The sample size was calculated as 160 each arm to detect 5 caries change with 80 power
Analysis The effect of intervention was measured in terms of number of caries prevented The number of new caries in the usual care and intervention group was calculated after the completion of the study The demographic and socioeconomic data of the intervention and usual care group were collected The costs for intervention were estimated The cost of treatment for caries was estimated for intervention and non-Intervention groups The costs for the dental material time for human resources and indirect costs were also calculated The results were presented as cost per caries prevented
