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: X-linked hypophosphatemic rickets (XLH) is characterised by severe skeletal deformities and dental abnormalities. The aim of this work is to examine the prevalence of abscesses, the features of pulp chambers, and the biochemical and histological signs of the disease.

Methods: Pulp chambers size, shape, and morphology were assessed by orthopantomography in XLH patients (n = 24, age 5.8 ± 1.6 years) and in sex and age-matched healthy controls (n = 23, age 6.2 ± 1.4 years). Histological analysis of the dentin of the primary teeth by Hematoxylin-eosin and Massontrichromic Goldner-blue aniline staining was then performed, comparing the results with those obtained in healthy controls.

Conclusion: Enlarged pulpal chambers with altered shape and morphology affect most XLH patients, setting them up for periapical abscesses with fistulas occurred without any history of trauma or dental decay. Patients with XLH should be considered high-risk patients. It is important to treat and manage them early by a multidisciplinary approach.

Background: The present study was designed to evaluate the enlargement of the nasal bone as side effect when a treatment with a Haas rapid maxillary expander is performed in early mixed dentition.

Methods: The CBCT imaging of 36 children (mean age 8,4; SD,1,5) were retrospectively selected and then traced in order to evaluate the change in the nasal bone (primary outcome) and in the maxilla (secondary outcome). Five distances and one angle were measured: upper and lower nasal bone width (UNBw and LNBw) as well as its inclination (NBi), and the maxillary bone at the level of infraorbital foramen (IOFw), the nasolacrimal duct (NLDd), and greater palatine foramina (PFd). The sample was divided in a treatment group (26 subjects; 14 males; 12 females; mean age 8,0; SD 0,9), comprising children who underwent to a rapid maxillary expansion, and a control group (10 subjects; 7 males; 3 females; mean age 9,3; SD 2,3) including untreated children homogeneous for dental age to the treated subjects. Measurements were performed at baseline or before the treatment (T0), and after 2 years (T1).

Conclusion: The transversal modification induced with a rapid maxillary expansion was limited to the maxilla without involving the nasal bones when the treatment was performed in early mixed dentition. The changes recorded in the nasal bones seem to be the same of what happens during normal growth.

Aim: Black stain (BS) is a peculiar discoloration often observed on the teeth of paediatric patients, particularly prevalent in certain populations. This systematic review aims to analyze the composition of the microbiota associated with BS and its potential implications for caries risk. A acomprehensive search was conducted across multiple databases (PubMed, Scopus, Web of Science) to identify relevant studies published up to January 2024. Eligible studies were those investigating the microbiological profile of BS patients compared to non-black stain individuals, with a focus on cariogenic species and overall microbial diversity. Data extraction and synthesis were performed following PRISMA guidelines. The screening phase ended with selecting 14 publications for this work. The review explores the association between the microbiota of BS patients and caries prevalence or severity. Synthesising current evidence sheds light on the potential role of the microbiota in BS formation and its influence on caries susceptibility. Understanding these microbial dynamics may inform preventive strategies and therapeutic interventions tailored to mitigate caries risk in populations affected by BS. This review underscores the significance of further research to elucidate the complex relationship between BS, oral microbiota, and dental caries.

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: This study aimed to investigate the caries activity (CA) and its caries status in children aged 3-5 years in Zhao County, Hebei province, China and to explore the related factors.

Methods: Cariostat caries activity test and oral examination were performed on children aged 3-5 years old in Zhao county, Hebei province by a stratified sampling. A questionnaire survey was used to analyze the CA-related factors and the receiver operating characteristic curve (ROC) was to evaluate the diagnostic value of Cariostat caries activity test in children with early childhood caries (ECC).

Conclusion: The caries status among preschool children in Zhao county of Hebei province was serious. The higher the mean dmft of children, the greater the CA value. Mother's educational level and children's diet and lifestyle habits were closely related to CA. The Cariostat caries activity test has good efficacy in diagnosing ECC with high sensitivity and specificity.

Background: Infraocclusion refers to a tooth located below the occlusal surface compared to adjacent teeth long after it should have reached occlusion. Ankylosis is frequently associated with the infraocclusion of primary molars, but it is challenging to distinguish between the two conditions. Surgical luxation and orthodontic traction have been applied for the treatment of ankylosed, infraoccluded permanent teeth, but reports on primary molars are scarce.

Case report: A 5-year-old boy presented with a severely infraoccluded primary mandibular second molar with deep caries. A partial pulpotomy was performed to treat the affected tooth when the pulp was exposed after caries removal. A combination of surgical luxation and orthodontic tractionwas performed for the affected tooth, and after 5 months, the tooth successfully erupted to the occlusal level. During the follow-up period of two years, no complications were observed.

Conclusion: This report identified that surgical luxation, in conjunction with orthodontic traction, is effective and feasible for severely infraoccluded primary teeth. Additionally, partial pulpotomy may be an alternative for vital pulp therapy on primary teeth.

Aim: The aim of this research is examining the effectiveness of Virtual Reality (VR) in the reduction of dental anxiety in children with novel methods.

Methods: The three arm parallel-group randomised clinical study was conducted in children aged 6-10 years. Pulpotomy procedure was performed on randomised 90 selected children (n=30 in each group; AG: group applied active distraction using VR glasses, PG: group applied passive distraction, i.e., watching cartoons on a screen mounted onto a dental unit, CG: control group). Before and after the procedure, children were administered Facial Pain Scale (FIS), Children's Fear Rating Scale (CFSS-DS) and Frankl Behaviour Rating Scale (FBRS). The pulse rate was measured to check the anxiety levels of all treated children at five different time points. Statistical significance was determined as p<0.05.

Conclusion: VR has been found to positively contribute to the performance of children in adapting to dental treatment. The VR application aims to create positive attitude in children by providing them a safe atmosphere and becoming a useful tool in the dental profession.

Aim: To examine the impact of medication on asthma treatment and the occurrence of caries cavities in children aged 3 to 15 years old (Luz Hospital in Lisbon, Portugal). The frequency of caries cavities in 3 different groups was examined. In addition, the possible association of caries cavities with different asthmatic medication was also assessed.

Background: Asthma and caries cavities affect many children worldwide. Investigating the connection between asthma medication and the development of caries cavities is important for enhancing asthma treatment while reducing oral health risks. Exploring the relationship between asthma medication and caries cavities is compelling due to the limited number of conclusive studies on the subject.

Materials: A descriptive observational study was conducted on children aged 3 to 15 years old, who attended the immunology-allergology and dentistry services at the Luz Hospital in Lisbon, Portugal. between January 2021 and February 2022. The sample was divided into 3 groups (medicated asthmatics, unmedicated asthmatics, and healthy children without asthma). An intraoral examination was performed to collect the DMFT index (decayed, missing, and filled teeth) to assess the presence of caries cavities. Clinical and dietary data were supplemented with a questionnaire and medical history in all groups. All variables used were qualitative and described using absolute frequencies and percentages.

Conclusion: These results showed that anti-asthmatic medications may influence the development of caries cavities. The occurrence of caries cavities is more prominent in medicated asthmatic children when compared to unmedicated asthmatic children.
