Background: It is quite common for white spots to develop on a tooth, due sometimes to a defective formation of the enamel layer, and sometimes to patches of demineralisation as a result of poor oral hygiene during orthodontic treatment with fixed braces. ICON DMG is currently the only noninvasive treatment for white spots. After a preliminary etching, it infiltrates the enamel, filling the spaces between the prisms with a resinous material that has a refraction coefficient very similar to that of healthy tooth enamel. The aim of this study was to test the efficacy of professional whitening procedures on teeth previously treated with ICON. The study hypothesis was that infiltration with ICON resin creates a barrier capable of preventing the bleaching action of the whitening agent.

Materials: White spots were artificially created on one half of the vestibular surface of 12 human teeth, while the other half was protected with a composite adhesive. The white spots were infiltrated with ICON and the protective adhesive was subsequently removed. A professional teeth whitening procedure was then completed on both halves of the teeth. A statistical analysis was performed to compare spectrophotometric recordings obtained before and after the ICON infiltration and teeth whitening procedures.

Conclusion: The whitening procedure modified the colour of the teeth on the half not infiltrated with ICON (p<0.05), but there was no statistically significant change in colour on the half infiltrated with ICON. The presence of the ICON resin seems to act as a partial barrier to the action of the whitening agent.

Aim: For a few years, teledentistry has been an emerging innovative strategy with potential in the field of paediatric dentistry. There are still few studies in this regard, so further research is needed to verify and ensure that teledentistry is not only an accessible mode of communication, but above all effective and evidence-based. This study aimed to use a preliminary telematic approach to promote the compliance of patients in the developmental age during the first dental visit.

Materials: Two hundred patients were selected according to the eligibility criteria, and distributed in two groups: a study group with the preliminary telematic approach (ATP) before the first visit and a control group with traditional first visit without ATP. Through an ordinal semi-proportional regression model, the degrees of collaboration between the study and control groups were compared, correcting the estimate for age groups, the presence of systemic pathologies, disorders of cognition, attention and learning, degree of anxiety and previous medical-dental experiences.

Conclusion: The preliminary telematic approach could be useful as a support to the traditional paediatric dental visit, to promote better management and fidelity of the patient, reducing anxiety and increasing collaboration during the first visit.

Aim: To investigate the effect of 38% SDF and its serial dilutions on the Stem cells from Human Exfoliated Deciduous teeth (SHED) and its ability to release growth factors from deciduous dentine.

Methods: The viability of SHED post-exposure to 38%, 3.8%, 0.38%, 0.038%, and 0.0038% SDF were assessed at 2, 5, and 7 days using the CyQuant assay, and results were validated using the MTT assay. The osteogenic differentiation of the cells was also investigated post-exposure to 0.0038% SDF. The release of the growth factors; TGF-β1, FGF-b, BMP-2, and VEGF from deciduous dentin discs exposed to 38% SDF, 0.0038% SDF, Ca(OH)2, MTA, and 17% EDTA were examined using ELISA. Statistical analysis was performed using means and standard deviations (p < 0.05). Two-way ANOVA compared the means of more than two groups with Tukey's multiple comparison test. The unpaired t-test was also used to compare the differences between the two data sets.

Conclusion: 38% SDF released dentinogenic growth factors from dentin discs, potentially explaining its role in reactionary dentinogenesis. Moreover, 0.0038% SDF resulted in a non-cytotoxic concentration that enhanced cellular proliferation and released bioactive molecules from dentin comparable to the 38% concentration. After further investigations, the 0.0038% dilution of SDF could present itself as a clinical concentration.

Aim: To compare the efficacy of two remineralising toothpastes in children suffering from asthma and allergic rhinitis after a 6-month study.

Methods: 40 patients aged between 6-14 years with enamel demineralisations were enrolled for the study at the Unit of Dental Hygiene of the University of Pavia (Italy). The following indices were collected: Schiff air index (SAI), plaque index (PI), bleeding on probing (BoP), salivary pH, Basic Erosive Wear Examination (BEWE), susceptibility index (SI) for hard and soft tissues' pathologies, and decayed missing filled teeth (DMFT). After mechanical debridement with piezoelectric instrumentation and glycine powder, patients were equally divided into two groups: Group 1 using a toothpaste with zinc hydroxyapatite, and Group 2 using a toothpaste containing calcium sodium phosphosilicate. The toothpaste had to be used twice a day. The time frames of the study were: baseline (T0), after 1 month (T1), after 3 months (T2), after 6 months (T3).

Conclusion: The tested toothpastes can be proposed for home use in children with asthma and allergic rhinitis as they significantly reduced dental sensitivity and periodontal indices.

Aim: Periapical cysts of primary teeth are pathologic entities which are seldom encountered in the clinical practice. Most frequently, these lesions arise in correspondence with primary teeth presenting previous pulp therapy, severe carious lesions, or a history of previous trauma. The aim of the present study is to systematically review the treatment modalities of periapical cysts of the deciduous, along with the reporting of a clinical case.

Materials: A case of periapical cyst treated with marsupialization occurring in an 11-year-old patient is described. A literature search was devised to retrieve studies reporting the treatment of periapical cysts, and involved papers published in the Cochrane Oral Health Group specialist trials, MEDLINE via PubMed, and EMBASE up to March 2023. A total of 39 articles were retrieved. Following title and abstract analysis, 27 articles were selected for full-text analysis, with the final inclusion of 24 articles.

Conclusion: Periapical cysts of primary teeth present an overall good prognosis irrespective of the treatment option adopted. The performance of a prompt diagnosis appears of utmost importance, as the extraction of the primary teeth involved implies the management of the residual space for the correct positioning of the corresponding permanent teeth.

It has become clear that pregnant women have a high risk of developing oral diseases, both in the supporting tissues and in the teeth. This is precisely why the first meeting between the dentist and the mother-to-be should take place as early as possible, either while she is still planning her pregnancy or as soon as she becomes pregnant. During this appointment it is appropriate to examine the presence of any risk factors for the future mother's oral health such as medication intake, presence of chronic pathologies or bad habits (smoking). The woman must be informed of all the changes that may occur during this period and that may negatively affect the pregnancy itself and the health (not only oral) of the foetus. At the same time, all the most important indications regarding correct oral hygiene, dietary and fluoroprophylaxis practices that all pregnant women should follow to ensure optimal oral health for themselves and their newborn child should be provided. In addition to this counselling phase, it is strictly the dentist's responsibility to proceed with the diagnostic phase, thanks to which he or she will be able to assess the woman's oral condition and, in the presence of pathological pictures, plan all the therapeutic interventions necessary to achieve a healthy condition before the beginning of such a delicate period. And why not, to lay the foundations for a life-long oral health!

Aim: There is a lack of sufficient information about the protocols followed by paediatric dentists in informing parents about traumatic dental injuries as a part of anticipatory guidance. Hence, the aim of this study was to assess paediatric dentists' attitudes and practices about parental guidance regarding these injuries.

Materials: This was a cross-sectional survey conducted using a validated questionnaire emailed through Google form to approximately 2500 paediatric dentists in various world regions. The sampling method used was a list-based sampling frame followed by simple random sampling. Participants were recruited through national member societies of the International Association of Paediatric Dentistry, personal contacts and social media groups. Only paediatric dentists with at least three years of experience after their post-graduation were only included in the study. Their attitudes and practices towards parental education on dental trauma during the child's first and recalled dental visits were assessed as per their age, gender, country of post-graduation qualification and years of experience in the profession. Chi-Square test was used to evaluate the association between the paediatric dentist response and the continent of practice. Kruskal-Wallis H test was used to assess the level of significance within each variable in relation to the continent of practice. A 95% confidence interval with a significance level of α = 0.05 was used.

Conclusion: The overall attitude and practice of paediatric dentists toward parental education on traumatic dental injuries were not satisfactory. Many paediatric dentists do not impart education on emergency care and dental trauma prevention in primary teeth. Parents should be informed about oral hygiene instructions and prevention-oriented interventions during the first visit and about managing traumatic dental injuries.

Aim: During adolescence, there is a significant surge in height and total body mass of males. Consequently, they simultaneously experience enhancements in their circulatory and respiratory systems, which adapt to these physiological transformations. The purpose of present study was to investigate the developmental changes in male pharyngeal airway from adolescence to adulthood.

Methods: Lateral cephalograms of 192 males were obtained and divided into 5 groups: early adolescence (age 10-13 years), middle adolescence (age 14-17 years), late adolescence (age 18-21 years), early adulthood (age 22-30 years), and middle adulthood (ages 31-50 years). The dimensions of pharyngeal airway spaces and the related anatomical structures were investigated. The one-way analysis of variance and Pearson correlation analysis were employed for statistical analysis.

Conclusion: During middle adolescence, the pharyngeal airway seems to be nearly completed in males. A significant negative correlation was found between the ANB angle and SPS, TPS, and EPS values.
