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: 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.

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.

Aim: Prosthetic rehabilitation of deciduous teeth in paediatric age using pre-formed crowns has been considered one of the best methods of dental restoration since their introduction. Their main advantages are related to durability, longevity and a low rate of recurrent cavities. Since stainless steel crowns do not coincide with aesthetic needs of parents and patients, preformed paedodontic crowns made of zirconia and nano-hybrid composite was introduced. The aim of the study is to evaluate the degree of wear on the enamel and on themselves of the different paedodontic crowns.

Materials: Nine bovine teeth and nine paedodontic crowns for deciduous molars were selected for the study, three of which in zirconia, three in nano-hybrid composite and three in stainless steel. Wear test was carried out on the Rtech™ Instruments tribometer applying a force of 50 N. After that, both the bovine teeth and the paedodontic crowns were observed using a stereo microscope (Zeiss Stemi C-500) and a scanning electron microscope (SEM, Cambridge Stereoscan 440). The areas of wear were calculated with a software [ImageJ, version 1x, Wayne Rasband, Maryland, USA].

Conclusion: Pre-formed paediatric crowns in zirconia, nano-hybrid composite and stainless steel are a valid aid for the restoration of deciduous teeth and do not compromise the physiological wear characteristic of the phases of the dental exchange. The stainless steel crown is preferable for the restorations in the posterior sectors as its behaviour is the most similar to that of a natural tooth. Zirconia and nano-hybrid composite crowns showed an inversely proportional behaviour between their wear volume and that of the opposing tooth.
