Dental and stomatologic problems in childhood need to be diagnosed and managed with multidisciplinary protocols focusing around the children an appropriate prevention, diagnosis, and care program. Therefore, it is paramount to avail of screening tools that provide an indication of in-depth multidisciplinary diagnostic flow. The aim of this study is to detect and evaluate malocclusion problems and predisposing factors in an Italian preschooler population. Design-calibrated operators detected data through examination of 1,405 children (706 males and 699 females) aged between 2 and 7 years, in one hospital in Rome and in kindergartens of several Italian cities. Data were collected following Risk of Malocclusion Assessment index criteria. Pearson's chi-square test (with continuity correction) and Fisher's exact test were the statistical tests conducted ( P  < 0.05). Grade 2 (49.6%) and 4 (21.7%), followed by grade 1 (17.1%), grade 3 (9.3%), and finally grade 5 (2.3%) are the most represented degrees. 53.6% of the cases have a high risk, whereas 32.2% has a low risk and 14.9% has a moderate risk. The risk-degree correlation is statistically significant ( P  < 0.005). Flawed habits and oral breathing are present in more than a quarter of children. Findings of the study highlighted that early multidisciplinary approach, as well as orthodontic visits and screening in childhood, is necessary to promote normal growth and development of the face and the elimination of potential interferences that may harm these processes., Competing Interests: The authors declare they have no conflict of interest.

Aim: The aim of the present work is to investigate whether dental decoronation is a procedure known by a sample of dental students and Italian dentists. Dental decoronation technique is performed in order to mitigate the outcomes which may occur after a delayed tooth replantation., Materials and Methods: A cognitive survey about the knowledge of the dental decoronation technique was carried on two groups: a sample of 120 dental students (5th year of dental school), from University of Cagliari, Sassari and of Chieti-Pescara (60 males and 60 females), and a group which involved 200 Italian dentists (age comprised between 25 and 45, 130 females and 70 males) enrolled at pedodontics and orthodontics Masters and CE courses (University of Roma Sapienza, Chieti- Pescara, Cagliari). The latter group's main field of work was paediatric dentistry and orthodontics, two dental specialties often involved in treating Traumatic dental injuries., Results: Only 20 dentists out of the 200 interviewed answered that they knew this technique and only 5 of them proved to know it and were able to describe it correctly. No students interviewed knew this technique., Conclusion: It is apparent from the results of this survey that there is very little information about the dental decoronation technique both during the Degree Course in Dentistry and Post Graduate specialty programmes (Continuing Education Courses and Masters).

Aim: The purpose of the study was to evaluate the efficacy of the guidelines on oral health published by the Italian Health Ministry., Study Design: 1239 patients (582 girls and 657 boys) with a mean age of 4.46 (SD 2.81) years were evaluated before application of the guidelines by paediatricians (T0) for the presence of caries, gingivitis, diseases of the oral mucosa, and malocclusion. Only patients aged 6 months, 3 years, 6 years, and 9 years at T0 were taken into consideration. All patients were reevaluated after application of the ministerial guidelines (T1)., Methods: the study took place over a 3-year period. Enrolled patients referred to the outpatient clinics of three paediatricians of the Province of Genoa who strictly applied the ministerial guidelines., Statistics: Chi square test analysis was performed to evaluate a statistically significant decrease in the incidence of caries, gingivitis and diseases of the oral mucosa., Results: After a 3-year follow-up collected data underlined a statistically significant decrease in the incidence of dental caries, gingivitis and oral mucosal diseases after implementation of the recommended ministerial guidelines. A statistically significant decrease of malocclusions was also evident in the elder patients (12 years old at T1)., Conclusion: The accurate implementation of the Guidelines is supported. Only collaboration and increased synergy between paedodontists and paediatricians can fulfill the objectives which were the reason for publishing the "National guidelines for the promotion of oral health and the prevention of oral diseases in developmental age".

Background: The role of third molars as a cause of incisor crowding, especially in the lower arch, continues to be controversial. The aim of this work is to compare opinions of Italian oral surgeons and orthodontists on this topic., Methods: One hundred ninety-three Italian practitioners of the Society of Orthodontics (SIDO) and the Italian Society of Oral Surgery (SICOI) were asked to fill out an online questionnaire made up of six questions. Practitioners were asked to express their opinion on the relation between upper and lower third molar eruption and anterior crowding., Results: One hundred sixty-six members of both societies completed the online research survey; response rate (RR) was 86%. There were no statistically significant differences between the two groups (P > 0.005). Both agree not to believe that third molars create a force responsible for anterior crowding in the upper (82.5% orthodontists, 83.8% surgeons) and in the lower arch (52.6% orthodontists, 63.8% surgeons). Both agree also not to consider the upper (89.7% orthodontists, 82.1% surgeons) and lower (58.8% orthodontists, 63.2% surgeons) third molar extraction useful to prevent crowding., Conclusions: Italian orthodontists and oral surgeons have the same opinion on the role of the third molar in causing anterior crowding. The majority of both groups of clinicians do not consider their preventive extraction useful in order to prevent anterior crowding.

Aim: The aim of this epidemiological study was to describe the incidence and distribution of hyperdontia in the primary school population in Genoa (Italy) and to check its influence on the development of orthodontic problems in children. The collected data should also help to find out what is the best age range among children to direct a program for early diagnosis and prevention of malocclusion and oral diseases related to hyperdontia., Methods: The participating children (total number 1577, 814 males and 763 females, between 6 and 10 years of age) chosen in 19 public primary schools in Genoa have been examined by the same specialist through year 2004. Erupted permanent teeth, presence, position and form of supernumerary teeth, malocclusion presence and class, presence of orthodontic devices, age and sex have been noted down for each child., Results: The global percentage of hyperdontia was 0.38%, more frequent in males (0.49%) than in females (0.26%). The most common kind of supernumerary tooth was mesiodens (83%). A significant increase of hyperdontia prevalence (from 0.64% to 1.06%) was noticed in children 9 years old. The incidence of malocclusion among children presenting hyperdontia was 83.3%, while the global incidence of malocclusion was 40%. An orthodontic treatment had been planned and started for 20% of children presenting malocclusion., Conclusion: The study has revealed an incidence of hyperdontia much more frequent in males than in females (2:1). The most common site of eruption of supernumerary teeth is maxillary anterior region. Hyperdontia is strictly related with dental malocclusion. The best age range to direct a program of early diagnosis and prevention of malocclusion and hyperdontia is 9 years old children.

The results of a dental screening performed on 251 pupils from 3 year-old to 5 year-old are reported. The data texted were: oral hygiene degree decayed milk-teeth, decayed permanent teeth, dental and facial anomalies in accordance with WHO classification Geneve 1977.
