Mothers' Awareness of the Correlation between Their Own and Their Children's Oral Health

Maintaining Hygiene in Orthodontic Miniscrews: Patient Management and Protocols-A Literature Review

BACKGROUND

Oral hygiene is crucial for the success of orthodontic therapy involving temporary anchoring devices like miniscrews. Plaque buildup, exacerbated by orthodontic appliances, causes inflammation that can undermine treatment outcomes. Individualized prevention plans based on patient risk factors are essential. This review emphasizes the importance of oral hygiene in orthodontic therapy with miniscrews, identifies optimal devices for ensuring long-term stability, and explores protocols for high-risk patients.

MATERIALS AND METHODS

A comprehensive search was conducted on two primary databases, PubMed and Google Scholar, for relevant articles on oral hygiene and inflammation. Fourteen articles meeting the inclusion criteria were selected, covering topics such as "orthodontic miniscrew", "miniscrew and laser", "miniscrew and mouthwash", "electric toothbrush", and "GBT".

RESULTS

Inflammation can compromise miniscrew stability by damaging surrounding bone. Miniscrews of 10 mm length have lower failure rates due to better bone contact and stability. Chlorhexidine reduces inflammation risk and inhibits epithelialization around the implant head. Laser therapy enhances miniscrew stability and reduces inflammation. Chitosan effectively suppresses inflammatory mediators and prevents microorganism adhesion. Both sonic and roto-oscillating electric toothbrushes remove plaque effectively, with roto-oscillating brushes showing superior results. The Guided Biofilm Therapy (GBT) protocol offers professional hygiene benefits similar to traditional methods, with improved patient engagement and motivation.

CONCLUSIONS

Home oral hygiene maintenance is paramount for preventing inflammatory complications. Professional interventions such as diode laser usage, particularly in adult patients with a history of periodontitis or underlying systemic conditions, can mitigate orthodontic therapy failure risks. The GBT protocol fosters a more comfortable and participatory professional hygiene experience for patients, promoting better oral health awareness and compliance.

Impact of Socioeconomic Inequalities on Dental Caries Status in Sardinian Children

BACKGROUND

The association between oral health of schoolchildren living in the North Sardinia area and socioeconomic deprivation was assessed to evaluate a potential spatial correlation.

METHODS

A total of 10,947 subjects were examined (5281 aged 3-5-years, and 5666 aged 6-11-years). The WHO dmft index score was calculated following clinical examination by calibrated examiners. The Sardinian Deprivation Index (IDMS) of the children's municipalities was also considered. Descriptive, bivariate and multinomial data analysis was conducted to assess the association between clinical data and socioeconomic deprivation. The presence of systematic spatial variation regarding caries experience (dmft) and deprivation status was investigated using a spatial autoregressive analysis.

RESULTS

Caries figures were statistically different in the two age groups (dmf > 0, 13.79% in the younger group vs. dmf > 0, 34.20% in the older one, p < 0.01). In a multinomial logistic regression model for caries experience, all the covariates were statistically significantly associated (p < 0.01) in comparison with the base outcome "caries-free". Linear regression analysis showed a dependence of dmft on IDMS (p < 0.01). Based on this equation, the dmft of the 39 municipalities that did not participate in the survey was estimated. IDMS was statistically significantly associated (p < 0.01) with caries prevalence in the spatial regression model.

CONCLUSIONS

The deprivation index significantly increased the risk of caries for all categories of caries experience and prevalence compared to caries-free. The relationship between IDMS and caries data was also confirmed by spatial analysis.

Is Parental Rating of Child's Oral Health Associated with Caries Experience in Children? A Cross-Sectional Study

Aim

The Parents' view to the oral health of their children is a significant factor that can impact oral health practices and behaviors. The aim of this research was to investigate how parental assessment of their child's oral health associates with caries experience in children receiving dental treatment at the hospital of Taibah University Dental College.

Materials and Methods

This cross-sectional study enrolled 127 children who underwent dental treatment at Taibah University Dental College and Hospital during 2020-2021. Dental caries experience was assessed using the dmft/DMFT index, and parental rating of oral health was obtained through a questionnaire. Three logistic regression models were used to assess the correlation between dental caries experience and parental rating of oral health while controlling for sociodemographic and behavioral factors.

Results

Most parents rated the oral health of their child as good (60.4%), followed by excellent (18.8%) and very good (15.6%). The mean dmft/DMFT score was 3.47 ± 3.46, with 43.8% of children having high/very high dental caries experience. Logistic regression analysis showed that children whose parents rated their oral health as poor were more likely to have high/very high dental caries experience compared to those rated as excellent/very good/good/fair (adjusted odds ratio = 4.45, 95% confidence interval 1.23-16.07).

Conclusion

This study suggests a link between parental assessment of their child's oral health and an elevated prevalence of dental caries in children. The study found that children whose parents rated their oral health as suboptimal had higher odds of having high dental caries experience. These findings emphasize the significance of parental perception of their child's oral health and suggest a necessity for customized interventions to enhance parental knowledge and practices concerning children's oral health.

Dual Stimuli-Responsive Orthodontic Aligners: An In Vitro Study

Aligner therapy for orthodontic tooth movement is gaining importance in orthodontics. The aim of this contribution is to introduce a thermo- and water-responsive shape memory polymer (SMP), which could lay the foundation for a new type of aligner therapy. The thermal, thermo-mechanical, and shape memory properties of thermoplastic polyurethane were studied by means of differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), and various practical experiments. The glass transition temperature of the SMP relevant for later switching was determined to be 50 °C in the DSC, while the tan δ peak was detected at 60 °C in the DMA. A biological evaluation was carried out using mouse fibroblast cells, which showed that the SMP is not cytotoxic in vitro. On a digitally designed and additively manufactured dental model, four aligners were fabricated from an injection-molded foil using a thermoforming process. The aligners were then heated and placed on a second denture model which had a malocclusion. After cooling, the aligners were in a programmed shape. The movement of a loose, artificial tooth and thus the correction of the malocclusion could be realized by thermal triggering the shape memory effect, at which the aligner corrected a displacement with an arc length of approximately 3.5 mm. The developed maximum force was separately determined to be about 1 N. Moreover, shape recovery of another aligner was realized within 20 h in 37 °C water. In perspective, the present approach can help to reduce the number of orthodontic aligners in therapy and thus avoid excessive material waste.
