Aim: To compare how parents' attitudes, knowledge, and sociodemographic characteristics influence untreated early childhood caries in infants and preschoolers in Brazil and Colombia.

Background: Dental caries is a prevalent chronic disease affecting children worldwide. However, little research has explored the connection between parents' knowledge, attitudes, and beliefs about oral health and the occurrence of dental caries in their children's primary teeth.

Materials: Oral health information was evaluated in children aged 3 to 5 years with a questionnaire covering sociodemographic and socioeconomic variables, family information and questions about health knowledge and child's and parents' oral health. In addition, oral examinations have been carried out to determine the prevalence of untreated dental caries. A p-value of 0.05 and 95% reliability level were considered statistically significant.

Conclusion: Untreated caries in infants and preschoolers are influenced by socioeconomic status, maternal education, sugar consumption, oral hygiene, and parents' beliefs about primary dentition.

Background: Odontomas are the most common odontogenic tumours, often considered hamartomas rather than true neoplasms. These mixed tumours consist of fully differentiated dental tissues, including enamel, dentin, cementum, and pulp. Odontomas can be classified into compound and complex types. While typically asymptomatic, they are often discovered during routine radiographic examinations for delayed tooth eruption. The management of odontomas generally involves surgical removal, which is effective in resolving associated dental impactions.

Case report: We present the case of a healthy 4-year-old child who presented with the absence of the lower left deciduous canine (tooth 7.3) in the dental arch. Radiographic examination revealed multiple radiopaque masses indicative of a compound odontoma associated with the unerupted deciduous canine. Following detailed imaging and surgical planning, the odontoma was successfully enucleated under conscious sedation with nitrous oxide. The surgical procedure was performed without extracting the retained canine. Post-operative follow-up at two weeks showed excellent healing, and at seven months, partial eruption of the canine was observed, confirming the odontoma's role in impeding its eruption.

Conclusion: This case underscores the importance of early diagnosis and management of odontomas to prevent potential impaction of associated teeth. The successful surgical removal of the odontoma facilitated the spontaneous eruption of the lower left deciduous canine, highlighting the effectiveness of early intervention. Conscious sedation with nitrous oxide proved to be a valuable tool in managing the young patient, ensuring cooperation and comfort during the procedure. Early identification and treatment of odontomas are crucial for promoting normal dental development and preventing future malocclusions.

Aim: This study aimed to characterise the palatal vault evolution during the first years of life, both in terms of shape and size.

Materials: The study sample was composed of 168 healthy children aged less than 4 years. Twenty-one measurements of distances and 6 angles were taken from 7 fixed landmarks set on the palatal vaults 3D surfaces reconstructed from CT-scans. To analyse only the shape evolution, the "sizefree" log-shape ratio of those measurements were computed and the global shape of the palatal vault and their transversal curve were plotted. Statistical analyses were performed to highlight the shape and size differences separately.

Conclusion: The shape and size evolution of the palatal vault during the first years of life was not only correlated with deciduous dentition development. We assumed that the progressive orofacial muscles activation and tongue movements in the oral cavity may also explain these results as they induced strains on the palatal vault, warping it in various ways.

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.

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.

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.

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: 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.
