Aim: To determine the factors associated with behaviours, attitudes and knowledge of parents about children's toothbrushing (CTB).

Methods: This is a cross-sectional analytical study of a calculated sample of 3,534 parents/guardians (92.6% female; 7.4% male; average age = 34 years [29-37]) of schoolchildren aged 3 to 8 years in 19 public schools in the province of Callao (Peru). A 31-item face-to-face/virtual questionnaire was divided into: 5 behavioural (18 (IQR)=3]; good 76%), 5 attitudes (13 [IQR=4]; negative 74.2%) and 10 knowledge (12 [IQR=4]; low 92.8%) (KMO≥0.537, Bartlett<0,001) and reliability (ω≥0.537) and 11 demographic domains. Bivariate and multivariate linear Poisson models were used with a P<0.05.

Conclusion: Children of parents with a higher education showed good behaviours related to CTB. Negative parental attitudes and low knowledge about CTB were associated with a lower parental education and toothbrushing frequency.

Background: Malocclusions are usually diagnosed around 3-4 years of age according to specific criteria. The purpose of this protocol is to validate a method to understand how the type of delivery can influence the development of malocclusions.

Materials: This pilot study, conducted at the Fondazione IRCCS Cà Granda Ospedale Maggiore Policlinico of Milan, evaluated the relationship between the type of delivery, fetal presentation, and the presence of malocclusions in children. The sample included 5 healthy term newborns, all born to healthy mothers with uncomplicated pregnancies by vaginal delivery. Measurements were taken, via ultrasound, at the 37th week of gestation (T0) and on the second day of life (T1), using a craniometer, caliper and goniometer, including head circumference, lower facial angle, frontonasal angle, labial fissure length, and interpupillary distance.

Conclusion: The results suggest that further research is necessary to better understand the influence of delivery mode and fetal presentation on the development of malocclusions. This study represents an important first step, highlighting the need for larger samples and more in-depth investigation methods to obtain more conclusive results.

Aim: To assess the clinical and radiographic success rates of regenerative pulpotomy compared to devitalising or preservative pulpotomy in treating vital pulp exposure in primary teeth.

Methods: Comprehensive search with PubMed/MEDLINE, Cochrane Library, Web of Science, Google Scholar and Open Grey databases was done and two reviewers extracted the data after assessing the studies for eligibility criteria. The Cochrane Collaboration Tool and Minors Checklist assessed the quality of the selected studies. A meta-analysis was performed using RevMan (P<0.05).

Conclusion: Within the limitations of the study, it can be concluded that MTA seemed to be the better alternative to FC and FS, showing a lower risk of failure and can be recommended for pulpotomy in primary teeth. BD also demonstrated promising results as a pulpotomy medicament.

Aim: To evaluate palatal surface effects induced by LE and RPE, alongside spontaneous changes in an untreated group, and to compare differences in canine and molar inclination among the three groups.

Materials: This randomised clinical trial aimed to compare digital models pre- and post-treatment over 12 months in patients receiving tooth-borne Leaf Expander® (LE) and tooth-borne Hyrax-type maxillary expander (RPE) treatments, alongside untreated patients. Analysis included 24 LE patients (13 males, 11 females, mean age 8.5±1.5), 22 RPE patients (10 males, 12 females, mean age 7.9±1.6), and 17 untreated subjects (7 males, 10 females, mean age 8.1±1.2). Inclusion criteria comprised indications for maxillary expansion treatment, mixed dentition, CVMS ≤ 3, erupted first molars, and good oral hygiene. Digital models were obtained using an intraoral scanner pre- and post-treatment. Palatal surface, segmented into anterior, median, and posterior zones, and canine/molar inclination were measured at T0-T1 using VAM software as the primary and secondary endpoint. Statistical analyses involved paired-sample T-tests for intra-group comparisons and ANOVA tests with Bonferroni correction for inter-group comparisons.

Conclusion: No significant difference in palatal surface increment was found between the two experimental groups (LE and RPE); both demonstrated a significant increase in palatal surface. The greatest increment occurred in the median palate zone for both experimental groups. The increment in the untreated control group was not significant. Furthermore, the RPE group showed a greater inclination of permanent molars compared to those treated with LE, indicating that expansion with lighter and continuous forces may lead to fewer dental side effects.

Aim: This present study has two primary objectives: firstly, to compare the effectiveness of an electric toothbrush versus a manual toothbrush in biofilm removal; secondarily, to assess the effectiveness of individualised instructions provided by the operator.

Materials: Fifty-five paediatric patients were enrolled in the study. Data collection involved three main steps: 1) Pre-brushing PCR index collection; 2) Post-brushing PCR index collection; 3) Post-brushing PCR index collection after providing individual instructions. The tooth surfaces were colored with a liquid plaque detector. To assess whether there was a statistically significant difference in plaque values before and after brushing, a Wilcoxon signed-rank test was conducted. The Wilcoxon test with continuity correction was performed to compare the two brushing methods.

Conclusion: It is possible to confirm a correlation between instructions provided by the operator and lower plaque index. As regards the comparison between manual and electric toothbrush, in our study one tool did not emerge as more effective than the other.

Aim: Exogenous black pigmentations, commonly referred to as black stains (BS), are an acquired oral pathology, prevalent among children. The condition is characterized by black punctiform spots that are distributed variably on the lingual and vestibular surfaces of both deciduous and permanent teeth. These spots are predominantly located on the cervical third of the crown but can also be found on the middle third, until the crown third, of the affected tooth's crown. These stains present a therapeutic challenge due to their high recurrence rate and the often-insufficient oral hygiene practices among children and their caregivers. Although general dentists may not be familiar with the classification of BS, the clinical diagnosis of this condition is typically straightforward. There is still no consensus among researchers regarding the prevalence of BS, and the etiopathogenesis of this condition remains not fully understood. Although BS are not a serious pathology, many children and their families experience significant embarrassment, anxiety, and negative psychological effects due to the condition. Recent literature on the treatment of BS indicates that a universally effective clinical protocol has not yet been established. This study introduces a new classification based on therapeutic approach and a flow chart designed to assist paediatric dentists in managing BS with a focus on preventing recurrence.

Aim: This study aimed to evaluate the fracture resistance of space maintainers (SMs) produced using 3D-printable materials (metal, resin and polyetheretherketone [PEEK]) after thermal aging and compare them with conventional space maintainers.

Methods: A standardised typodont model for paediatric dentistry was utilised, and band and loop space maintainers were designed digitally using computer-aided design (CAD) technology. Four groups were established: Conventional, 3D printed metal, 3D printed resin, and 3D printed PEEK. Fracture resistance was assessed after 10,000 thermal cycles, simulating oral conditions. Fracture tests were conducted using a universal testing machine, applying vertical force to the band and loop junction until fracture. Statistical analyses were performed using one-way ANOVA and the Tukey HSD test (P<0.05).

Conclusion: Although the fracture resistance values showed that metal, resin, and PEEK 3D printed band and loop space maintainers can be acceptable clinically, the permanent resin may be preferable to printable material because of their aesthetic properties.

Aim: The present systematic review and meta-analysis (Prospero registration number: CRD42023472016) aims to assess the prevalence of developmental defects of enamel (DDEs), qualitatively and/or quantitatively, in childhood cancer survivors (CCS) and evaluate, when possible, these data in comparison with those found in healthy children.

Methods: Three electronic databases (PubMed, Embase, Scopus) were searched from January 2003 to January 2024 for studies reporting on DDEs in children with a mean age not exceeding 16 years at the time of the study who underwent antineoplastic therapy. The ROBINS-I and the Joanna Briggs Institute (JBI) tools were used to assess the risk of bias. Included studies with comparable outcomes underwent random effects models meta-analysis using Stata®18.

Conclusion: CCS showed a higher prevalence of DDEs, both qualitative and quantitative, compared to healthy children. The meta- analysis showed higher odds of developing qualitative defects over quantitative defects in CCS. Conclusions regarding the association between the type of therapy administered, age of therapy initiation, and prevalence of DDEs could not be drawn due to insufficient data. A lack of a standardized method of detecting enamel defects posed a challenge in the qualitative and quantitative analysis.

Aim: The primary goal of the present comprehensive systematic review is to assess the treatment results attained through PSIO in individuals with NSCLP, as well as to explore its effectiveness. This will be accomplished by examining a range of existing published studies that focus on patient groups who have undergone PPIO.

Materials: A comprehensive search strategy was devised by a single author for each database without language restrictions. The databases searched were PubMed, Cochrane library Google Scholar, Web of Science and Scopus. The search period was limited to the years 2001 to 2023. Duration and study design filter was used. Furthermore, conference proceedings, abstracts, and reference lists of relevant studies were sought to obtain additional records.

Conclusion: The examined protocols for passive presurgical infant orthopaedics (PPIO) in individuals with CLP typically did not reveal notable treatment outcomes when compared to a lack of treatment across a range of domains. These domains encompass feeding patterns, facial aesthetics, maxillary dentoalveolar factors, cephalometric measurements, speech and language-related aspects, dental arch alignments, economic assessments, as well as occurrences of adverse effects or complications associated with applied appliances or procedures.

Aim: Over the years, the role of the lingual frenulum in the development of skeletal structures has been evaluated. However, the effect of short lingual frenulum treatment on bone structures is unclear. We need to investigate the effect of surgery and myofunctional therapy on maxillary development. This could be the rationale to establish an orthodontic interception protocol.

Methods: The case-control study was carried out in the Operative Unit of Pedodontics of the University Dental Clinic, at the Department of Medical, Oral and Biotechnological Sciences of the University of "G. D'Annunzio" Chieti-Pescara. The study population consisted in thirty children. The data were collected through anamnesis carried out by qualified health personnel before dental examination. Photos, frenulum length and cast measurements were taken. Student's t-test statistical analysis was used. Significance was ascertained based on the obtained P value of less than 0.01.

Conclusion: The results confirmed the benefit of laser surgical treatment. The change in parameters related to the anterior palate region showed the power of frenectomy and myofunctional therapy in restoring the tongue's ability to stimulate bone development. The protocol adopted in the following study could be used in interceptive orthodontics. However, further studies are needed to evaluate the effects on the upper jaw over the long term that have higher sample numbers.
