Tooth decay in children and adolescents remains a public health problem, despite prophylaxis and preventive measures being largely available. The aim of our study was to evaluate the clinical behavior of four dental sealants, related to first permanent molar topography and patient age (when sealant was applied for the first time). We assessed, by means of visual inspection and palpation with a dental probe, a group of 200 children, enrolled corresponding to school age-grade (mean age of 7 years at baseline) and randomly divided according to the material used as dental sealant (Admira seal©, Embrace Wet Bond©, Fotoseal©, GC Fuji Triaje©) in 4 groups (n = 50). Sealant clinical evaluation was made at 6-, 12-, 18-month intervals for dental material retention assessment. At 6 months, the sealant detached the most from 3.6 molars, and the material used was Fotoseal© (27.6%). At 12 months, Fotoseal© (48.3%) and GC Fuji Triaje© (41.4%) from 3.6 molars express detachment. At 18 months, 4.6. molars sealed with Admira Seal© (25.7%) and Embrace Wet Bond© (28.6%) lost the sealant. We noticed less detachment in maxillary molars and if sealant was applied around 7 years of age. In conclusion, sealant application on first permanent molars must be encouraged and practitioners can choose between various materials available.

Background/Objectives: Paediatric oral health during primary school years profoundly impacts systemic development and psychosocial wellbeing, with parental health habits heavily dictating whether care follows a preventive or a reactive pathway. The aim of this study was to evaluate parent-reported oral health status, oral hygiene habits, and dietary patterns in primary schoolchildren, as well as parental awareness regarding the impact of oral health on children’s overall wellbeing across preventive and reactive care pathways. Methods: A cross-sectional study was conducted, administering an online questionnaire to 1889 parents of primary schoolchildren, which evaluated the parent’s knowledge, behaviors and attitudes regarding the oral health and diet of their children. Results: Parent-perceived child oral and gum health was overall favorable, with girls (p<0.01) and children of parents with higher educational background (p<0.001) receiving higher ratings. While toothbrushing with fluoridated toothpaste was widely reported, fluoride usage and dental flossing remained heavily stratified by socio-demographic factors (p<0.001). The consumption of fruits, sweet bakeries and cariogenic snacks was frequent and soft drink intake demonstrated an age-dependent increase (p=0.001). Dental pain was rarely reported; increased pain frequency was correlated with poorer parent-perceived oral health ratings and cariogenic diets (p<0.001). Child dental visits were predominantly low or reactive, with non-attendance and pain-triggered visits significantly linked to rural residence, lower parental academic attainment, poor brushing frequency and cariogenic diets, which affected the children’s quality of life (p<0.001). Conclusions: Schoolchildren’s oral healthcare remains largely reactive, with dental pain serving as the primary trigger for dental service utilization, despite generally favorable parental perceptions.
