The aim of the study was to elucidate the crystallization potential of oral fluid in preterm children. A case-control clinical study was conducted on a sample of 978 children aged 1 to 15 years, divided into 2 proportionally structured groups. The research group L1 consisted of 326 preterm children (according to anamnesis data), and the control group L0 consisted of 652 conventionally healthy children. The prevalence index of dental caries (DC) was assessed. The potential for oral fluid crystallization (OFC) was analyzed. Dehydration of oral fluid (OF) droplets was carried out in a unit at t = 37 ℃, protected from dust. Micropreparations were examined under AmScope B120C-E1 Binocular Compound Microscope.The oral fluid crystallization potential (OFCP) in preterm children was low, measuring 1.89 ± 1.29 points, p < 0.001, in contrast to the high OFCP (OFCP = 3.67 ± 0.34) observed in conventionally healthy subjects. The OFCP in children from group L1 was 1.94 times lower than that in subjects from group L0. Conclusions: The decrease in OFCP represents an important etiological factor in the increased susceptibility to DC, particularly during the period of post-eruptive tooth mineralization. The identification of crystallographic features through the evaluation of OFCP offers a complementary diagnostic tool of practical value to predict DC. This approach enables the identification of individuals at higher risk for dental caries and provides an opportunity to select effective, personalized, and early preventive strategies.

摘要

The aim of the study was to elucidate the crystallization potential of oral fluid in preterm children. A case-control clinical study was conducted on a sample of 978 children aged 1 to 15 years, divided into 2 proportionally structured groups. The research group L1 consisted of 326 preterm children (according to anamnesis data), and the control group L0 consisted of 652 conventionally healthy children. The prevalence index of dental caries (DC) was assessed. The potential for oral fluid crystallization (OFC) was analyzed. Dehydration of oral fluid (OF) droplets was carried out in a unit at t = 37 ℃, protected from dust. Micropreparations were examined under AmScope B120C-E1 Binocular Compound Microscope.The oral fluid crystallization potential (OFCP) in preterm children was low, measuring 1.89 ± 1.29 points, p < 0.001, in contrast to the high OFCP (OFCP = 3.67 ± 0.34) observed in conventionally healthy subjects. The OFCP in children from group L1 was 1.94 times lower than that in subjects from group L0. Conclusions: The decrease in OFCP represents an important etiological factor in the increased susceptibility to DC, particularly during the period of post-eruptive tooth mineralization. The identification of crystallographic features through the evaluation of OFCP offers a complementary diagnostic tool of practical value to predict DC. This approach enables the identification of individuals at higher risk for dental caries and provides an opportunity to select effective, personalized, and early preventive strategies.
