Clinical efficacy of sealing and the role of fluorescence diagnostics in preventive aspects of fissural caries treatment
Keywords: fissural caries, fissure sealing, primary school children, caries prevention, fluorescent diagnostics, SIROInspect, light-curing sealants
Prevention of fissural caries in the first permanent molars during the period of mixed dentition remains highly relevant due to physiological immaturity of the enamel and complex morphology of fissures, which makes them highly susceptible to decay (up to 85.6% by the age of 9). Fissures sealing is the "gold standard" of prevention, and its modern development is associated with the introduction of methods for objective diagnosis of latent carious process. The aim of the study was to evaluate the caries-preventive effectiveness of sealing fissures using the SIROInspect fluorescent detector in children aged 7–12 years. Materials and methods. A prospective comparative study was performed (2021–2025). The main group included 56 patients who underwent fissures sealing on the first permanent molars after diagnosis using the SIROInspect detector and professional hygiene. The control group consisted of 34 persons who underwent routine examinations and hygiene training. Assessment by Ryge/USPHS criteria was carried out after 3, 6, 12, 24 months (simple blind method). The relative risk reduction index (RRR) was calculated. cTest ² and Student's t-test (p < 0.05) were used for statistical processing. Results. During the two-year follow-up, high sealing efficiency was demonstrated. Complete retention of the material (Ryge/USPHS class A) after 24 months was recorded in 52 of 56 teeth of the main group, which made 92.9%. The incidence of new carious lesions in fissures was statistically significantly lower in the main group compared to the control group, 1.8% and 29.4%, respectively (p < 0.01). The method's preventive effectiveness, calculated as a Relative Risk Reduction (RRR), reached 94.1%, which means a reduction in caries probability by more than 15 times. Preliminary diagnosis using SIROInspect fluorescence detector demonstrated its high diagnostic value: In 8 out of 46 teeth with open fissures (17.4%), hidden areas of demineralization were visualized that could not be detected during a standard examination. This required a change in tactics and minimal invasive preparation, followed by sealing these areas. Conclusions. Sealing the fissures in the first permanent molars in children aged 7–12 years with SIROInspect pre-fluorescence diagnosis confirmed its high caries-preventive efficacy. The use of this comprehensive approach, including professional hygiene, objective fluorescence diagnostics and subsequent sealing, ensured complete material retention at the level of 92.9% and reduced the risk of developing new carious lesions by 15 times compared with the control group, which corresponds to a relative risk reduction (RRR) of 94.1%.
