Fissure sealants (FS) are micro-invasive procedures that have proved to be effective in caries prevention in caries-free, first permanent molars. Within high-caries risk individuals, fissure sealants arrest the caries process in early caries lesions stages. Composite resin (CR) sealants have been recognized as the gold standard FS material; however, new evidence has emerged in relation to GIC sealants in their applicability and longevity. This review provides evidence-based information supporting the effectiveness of GIC sealants in caries prevention in comparison to CR sealants, by assessing their properties, methodology and utility in healthy and anomaly-affected teeth.
CPD/Clinical Relevance: This article will inform clinicians about the effectiveness of GIC sealants and CR sealants in caries prevention.
Article
Dental caries, regarded as the most preventable dental disease, impacts quality of life, particularly in those in lower socio-economic groups. Described as a non-communicable, dynamic biofilm-induced disease, dental caries develops from the imbalance between remineralization and demineralization processes in dental hard tissues and is influenced by biological, behavioural, and environmental factors.1 In the paediatric population, dental caries affects approximately 60–90% of school children globally, and negatively impacts eating, development and general psychosocial wellbeing resulting in the loss of school days and the inability to learn.1,2
Over the years, primary care has focused on delivering upstream interventions at a community level, and disease prevention at an individual level.1 Interventions such as fluoridated water or topical fluoride agents, diet advice, oral hygiene and fissure sealants are non-or minimally invasive approaches, which have been implemented to address the ongoing caries concern.1,2,3
