Background: Bullying is a common behaviour among adolescents, with psychological and health impacts on both victims and bullies. Recently, bullying due to dental features has received serious attention due to its short- and long-term effects on the health and well-being of children and adolescents. However, there is a scarcity of studies that investigate the impact of treating dental problems on the cessation of bullying. This study aims to identify the impact of dental features and treatment of dental problems on the experience of being bullied.

Methods: A self-administered, modified version of a validated Arabic questionnaire was distributed to 300 dental patients with an age range of 10-18 years old. The variables studied were demographics, bullying due to dental features, the impact of dental treatment on the experience of being bullied, and the need for a program to stop bullying.

Conclusion: Bullying due to dental features is common among adolescents. Treatment of dental problems significantly lessens the act of bullying. Implementing anti-bullying programs that include paedodontists and orthodontists as stakeholders is important.

Aim: The aim of the present study is to evaluate the relationship between sequential visits in dental caries treatments and dental anxiety levels of paediatric patients through the use of anxiety scales and physiological measurements.

Methods: A total of 224 children aged 5-8 years who needed at least two bilateral restorative dental caries treatments of the mandibular first primary molar was included in the study. The treatment duration was approximately 20 minutes and time span between the two appointments was a maximum of two weeks. The Wong-Baker FACES Pain Rating Scale (WBFPS) and The Modified Dental Anxiety Scale (MDAS) were used for subjective measurements and the objective measurement of dental anxiety was performed by measuring the heart rate using a portable pulse oximeter. Statistical analysis was carried out using the Statistical Package for the Social Sciences version 22 (IBM corp. Armonk, NY, USA).

Results: Out of the 224 children, 117 were girls (mean age 6.4 ± 1.1 years) and 107 were boys (mean age 6.1 ± 1.2 years). The mean age of the patients was 6.26 ± 1.147 years, ranging from 5 to 8. There were no statistical significant differences between children’s age and genders with dental anxiety. However, there were statistical significant differences for the variables regarding the sequential visits. When comparing the MDAS scores statistically significant differences were observed between the first and second visits (p<0.001). Both preoperative and postoperative WBFPS scores were significantly higher at the first visit than at the second visit. Statistically significant differences were observed in the heart rate scores between the treatment sessions (p<0.001).

Conclusion: The results of this study show a significant reduction in dental anxiety after sequental dental visits in children aged 5-8 years, which highlights the importance of the sequental visits in paediatric dentistry.

Aim: Dental agenesis is one of the most frequent dental anomalies, with a prevalence varying from 1.6% to 36.5%, depending on the populations studied. The patient's age at diagnosis, sex, and ethnic differences are considered possible influenting factors that can explain such a wide range of prevalence. The objective of the study was to define the frequency of dental agenesis in a sample of subjects living in Piedmont and Lombardy regions of Italy.

Materials: X-rays, already taken for other diagnostic purposes, were collected. Orthopantomographies belonging to subjects born after 1995 and aged between 7.9 and 16.9 years were selected. It was assessed the presence of each tooth, except for third molars since they are frequently absent due to their variability. If a tooth was missing and the patient had additional radiographs, the other radiographs were evaluated to confirm the diagnosis or to rule out a delayed calcification or the presence of a malposition tooth.

Results: Orthopantomographies were collected from 1,020 subjects and 98 of them presented agenesis, with a prevalence of 5% for females and 4.61% for males. The most affected teeth were 35 and 45, followed by 12 and 22. The lower arch was more frequently involved by agenesis: there were 107 teeth absent in the mandibular arch and 83 in the maxillary arch.

Aim: To compare the prevalence of mutans streptococci (SM) prevalence and categorical distribution in the saliva of high caries-risk children after their 24 months exposure to 25% xylitol toothpaste applied twice a day. To also examine the early caries susceptibility at baseline.

Background: An observational design with two times of collection. A total of 270 mother-infant dyads (mean age of infant 6.7 months) were initially recruited. At baseline, a dental exam looked for any early clinical signs of caries, and saliva collections were performed to assess SM prevalence. Two years later, other saliva collections were performed on a residual sample of 102 young children at the endpoint.

Methods: Two hundred four saliva samples were analysed with Dentocult, a commercial kit estimating in four categories, the SM distribution, expressed as the number of colonies forming units per milliliter of saliva (CFU/ml). The dental exam used the ICDAS system to include initial carious lesions (d1-2). The dentist administrated a maternal socio-economic questionnaire as the study collector.

Conclusion: A domestic strategy using a natural toothpaste containing 25% of xylitol as a vehicle, and tooth brushing as a habit, showed a promising antibacterial cariogenic effect. This approach could be a relevant alternative to in-home care to prevent ECC and early SM contamination.

Case report: Ameloblastic fibroma is a rare mixed odontogenic tumour which involves mostly the posterior mandible. Its peripheral variant is very rare. Only eight cases have been reported worldwide. In this report, we described a case of peripheral ameloblastic fibroma occurring in the maxillary gingiva in a 10 year-old child. The lesion was excised with a conservative surgical approach and no recurrence has occurred. Peripheral ameloblastic fibroma should be considered in the differential diagnosis of a slow growing lesion involving the gingiva.

Aim: The aim of this scoping review is to assess the application of new 3D printed polymeric materials in orthodontics, including polyamide-12 (PA-12) and Shape Memory Polymers (SMPs).

Methods: A search for articles published until January 2023 was carried out using PubMed, Scopus, Web of Knowledge, Lilacs, Opengrey, Embase and Cochrane Library databases and by applying the search terms (orthodontic* OR paediatric* OR paedodontic*) AND ("3D printed" OR "three-dimensional printed") AND (polymer* OR material* OR resin* OR technopolymer*). Additional records were also screened through hand or electronic search. No restriction in terms of language or publication period was applied.

Conclusion: Due to their mechanical, aesthetic and biocompatibility characteristics, PA12 and SMPs can be used in orthodontic practice. However, additional studies should be performed to evaluate the clinical efficiency of these recent materials.

Background: Proper development of deciduous and mixed dentition is essential to the oral health of growing patients, and early interceptive orthopedic or orthodontic treatments are indicated in specific clinical situations. Nowadays, orthodontists are subjected to a lot of pressure from growing patients and their parents about the orthodontic appliances that should be used. The aim of this article is to indicate how, when and why it is possible to effectively use aligners in growing patients.

Case report: Two case reports are illustrated, one with a Cl.II subdivision, mono lateral cross-bite and vertical growth, and the other with a skeletal and dental Cl.II, vertical skeletal pattern, proclined and fractured upper incisors. The efficacy/efficiency ratio of aligners is analyzed in order to evaluate the suitability of this appliance for the treatment. Limits and advantages of aligners are widely discussed.

Conclusion: Aligner treatment in growing patients shall be carefully studied to reach an optimal result. At present, a hybrid treatment strategy represents the best solution in growing patients with a complex clinical situation.

A healthy and balanced diet should be promoted already in childhood, a crucial period for the psychophysical development of the individual. In particular, the consumption of free sugars and soft drinks in children and adolescents should not exceed the current WHO recommendations. This trend is very difficult to counter as the preference for sweet flavours is innate and often further reinforced by pre- and post-natal exposure and aggressive marketing. Unfortunately, sugar consumption continues to grow alarmingly due in part to the easy availability of foods and drinks rich in added sugars from vending machines, supermarkets and fast-food restaurants. Recently, the WHO (with the recommendations included in the QR Code below and in the following link: WHO recommends stronger policies to protect children from the harmful impact of food marketing) pointed out how exposure to food marketing affects children's health, eating behaviours and beliefs about food, thus becoming a real threat to public health. Among the proposals made, it is interesting to note the need for national governments to "curb the persuasive power of food marketing" by limiting the use of cartoons and other techniques that appeal to children, such as the inclusion of toys in packaging or advertisements with songs and celebrity endorsements. It is already evident in the literature that an excessive intake of sugar predisposes children to a number of pathological conditions that in the long term may favour the onset not only of carious disease but also obesity, type 2 diabetes mellitus, liver disease, cardiovascular and dysmetabolic diseases. As paediatric dentists, sugar-related dietary excesses are already very obvious to us since it is mainly these that drive young patients to our clinics. In our privileged position, we should therefore increasingly promote knowledge on the possible correlations between excessive sugar consumption and the onset of these diseases, drawing the attention of parents of young patients to all foods that are harmful to their growing children. Therefore, let us welcome these new guidelines promoted by the WHO to protect children and adolescents from the harmful impact of food marketing; and may we not miss the opportunity to share and promote this important battle for future generations!

Aim: Patient compliance is of paramount importance for proper dental treatment, which can be difficult to achieve in children due to anxiety and fear, hindering the therapeutic procedure. In addition to well-known sedation methods (pharmacological and nitrous oxide), further methods of approach are being tested, such as hypnotherapy.

Materials: The sample consisted of 150 children (90 males, 60 females). Paper questionnaires, frequency meter, nitrous oxide dispenser in association with the use of the television were exploited. At the end of treatment, subjective pain was assessed using the VAS scale, while objective pain was assessed using the FLACC scale and heart rate. This made it possible to compare two experimental groups, one treated with nitrous oxide, and the other with hypnotherapy. The control group was treated with classic behavioural approach techniques. The results obtained were analysed by SPSS Software (Statistical Package for Social Science, version 27) and the inferences between the results were calculated for confirmation.

Conclusion: Hypnotherapy can be a valid substitute for nitrous oxide in paediatric dentistry.
