- Damage of the enamel after sealing occlusal fissure and pits : a systematic reviewPublication . Abrantes, Diana Dinis; Veiga, Nélio Jorge; Souza, Júlio César Matias de; Pereira, Rita Cristina Pais FidalgoIntroduction: Pit and fissure sealing is an effective preventive measure against dental caries, especially in high-risk patients, by creating a protective barrier. The procedure involves cleaning, conditioning, sealant application, and light curing. The choice of material influences the success of the treatment: composite resin sealants offer greater retention, while glass ionomer sealants release fluoride and are less technique sensitive. Despite challenges such as microcracks and wear, careful material selection and proper application ensure its effectiveness in caries prevention. Aim: Perform a systematic review between sealant adhesion and enamel damage after sealing occlusal pits and fissures with different modern materials and considering their impact on enamel. Materials and methods: A search was conducted in the electronic databases PubMed and Scopus. The research strategy used English keywords such as "damage" OR "degradation" OR "wear" OR "erosion" OR "corrosion" OR "demineralization" OR "roughness" AND "enamel" AND "fissure" OR "pit" AND "sealant". Studies in English from 2004 to October 2024 were included, covering in vitro trials, randomized clinical trials, and prospective cohort studies. Articles without abstracts, case reports with short follow-ups, and pilot studies were excluded. Studies were selected based on predefined inclusion and exclusion criteria. Results: Seventeen of the seventy-two initially identified studies were considered in this review since it respected the established research criteria. The qualitative analysis of the selected studies revealed some methodological limitations, resulting in heterogeneous data that prevent direct comparisons between studies. Conclusion: Pit and fissure sealing is effective in caries prevention but may cause enamel damage such as demineralization, microcracks, and mechanical wear. The choice of material and application technique influences these effects. Which means it is essential to adopt a careful approach to minimize adverse impacts and optimize clinical practice.
