Parental Knowledge, Attitudes, and Practices Regarding Early Childhood Caries in Bihor, Romania: A Cross-Sectional Study

BACKGROUND/OBJECTIVES

Early childhood caries (ECC) is a significant global health issue, particularly affecting deciduous teeth in young children. ECC is prevalent in Romania, where nearly half of children experience dental caries. This study aimed to assess the influence of gender, age, and living environment on parents' knowledge, attitudes, and practices (KAP) regarding ECC in Bihor County, Romania, using a KAP-type questionnaire.

METHODS

A cross-sectional study was conducted between March and September 2024, utilizing an online KAP questionnaire distributed via social networks. The sample comprised 419 parents of children under six years old. Respondents provided socio-demographic data and answered questions regarding their knowledge, attitudes, and practices concerning ECC prevention, treatment, and oral health. Statistical analysis was conducted using Chi-square tests to assess associations between demographic factors and parental KAP. A p-value of less than 0.05 was considered statistically significant.

RESULTS

Of the 419 respondents, 83.1% were female, and 62.5% were between the ages of 31 and 40. Significant gender-based differences were found in knowledge about pain from caries (93.7% of female participants vs. 81.7% of male participants, p = 0.004) and the importance of brushing twice daily (93.7% of female respondents vs. 80.3% of male respondents, p = 0.010). Younger parents (aged 18-30) were more likely to affirm the effectiveness of fluoride (65.4%) compared to those aged 31-40 (53.1%, p = 0.02). Urban parents were more likely to correctly identify the timing of tooth eruption (59.1% vs. 52.6% of rural parents, p = 0.021).

CONCLUSIONS

The study highlights gender, age, and urban-rural disparities in parental knowledge and attitudes towards ECC. These findings underscore the need for targeted educational interventions to improve oral health outcomes and reduce ECC prevalence in the Bihor region. Tailored public health strategies addressing demographic factors could enhance preventive oral health behaviors and reduce the healthcare burden associated with untreated dental caries.

Application of mineral trioxide aggregate pulpotomy in the treatment of early pulpitis of primary molars

OBJECTIVE

To evaluate the effectiveness of mineral trioxide aggregate (MTA) on pulpotomy in primary molars.

METHODS

Two hundred and sixty-three cases (310 teeth) of children with early pulpitis of primary molars admitted between February 2019 to February 2022 were enrolled, and their clinical data were retrospectively analyzed. Of them, 130 cases with 155 teeth treated with root canal treatment were set as the control group (CG) and 133 cases with 155 teeth receiving MTA pulpotomy were set as the observation group (OG). Clinical data such as efficacy evaluation, inflammatory factor levels, postoperative adverse reactions, and quality of life (QoL) were compared.

RESULTS

After surgery, the overall response rate in the OG was statistically higher than that in the CG, while the levels of inflammatory factors in the OG were significantly lower than those in the CG (all P<0.05). Moreover, the total incidence of complications was significantly lower in OG at 3, 6, and 12 months after surgery (P=0.018, P=0.007, P=0.015, respectively). The QoL of the two groups differed insignificantly before surgery; however, after the treatment, the QoL in OG was significantly higher than those in the CG at 3, 6, and 12 months after surgery (P=0.037, P=0.012, P=0.028, respectively). Moreover, the teeth location and treatment method were independent factors of efficacy (P=0.047, P=0.001, respectively).

CONCLUSIONS

MTA pulpotomy outperformed root canal treatment for superior efficacy in children with early pulpitis of primary molars, with a positive effect on improving QoL, and patient prognosis.

The effect of pulp inflammation and premature extraction of primary molars on the successor permanent teeth. A retrospective study

BACKGROUND

Untreated caries on primary molars often leads to pulp inflammation and extraction.

AIM

To retrospectively investigate the effect of pulp inflammation and extraction of primary molars on their successors regarding alignment in the dental arch and developmental enamel defects (DED).

DESIGN

The participants in this study were children at public schools in Petropolis (Brazil), who participated in a 3-year longitudinal clinical trial. Children (N = 44) were selected for the present study if they had at least one erupted premolar of which the predecessor primary molar presented pulp inflammation at baseline or during any of the 6-month follow-up assessments. All premolars were examined for DED and misalignment. Distinction was made between extraction performed before (E <8) or after the age of 8 years (E ≥8). Distinction was also made between pulp inflammation occurred before (P < 7) or after the age of 7 years (P ≥ 7). A logistic regression analysis was performed, and the odds ratio was calculated.

RESULTS AND CONCLUSIONS

Misalignment occurred more frequently in E <8 as compared to E ≥8 (OR = 2.85; P = .03). There was no significant difference in DED between P < 7 and P ≥ 7.

CONCLUSION

Misalignment of premolars occurs more frequently when the predecessor primary molars are extracted before the age of 8 years.
