Paediatric laser dentistry. Part 3: Dental trauma

Dental traumas are frequent and sometimes complex events, and at times real emergencies. There are no wellcoded guidelines for laser applications in these clinical events. Laser-assisted therapy can offer new treatment possibilities, simplify dental procedures, reduce postoperative sensitivity and the need for post-operative medications because of the laser-induced biostimulating and anti-inflammatory effects

Intrusive luxation of primary upper incisors and sequelae on permanent successors: A clinical follow-up study

5nononeAim: The purpose of this report is to evaluate the aepidemiological aspects of intrusion that occur against upper incisors in primary dentition, to determine the statistic correlation of developmental disturbances to permanent teeth in relation to age of children at the time of trauma. Materials and methods: A retrospective study was performed based on radiographic and clinical data of 34 intruded incisors in 30 patients aged between 12 and 60 months. Baseline data were collected in a questionnaire designed following the guidelines of the IADT-Italy. The descriptive statistical analysis between the different variables was performed with the Chi-squared test and the level of significance was set at 5%. The following parameters were considered: gender, age of patient at the time of injury, emergency treatment, clinical signs (vitality, mobility, spontaneous pain, colour change), presence of complications, degree of spontaneous reeruption and possible developmental disorders to the following tooth. Results: Intrusive luxation is not statistically related to gender. During the first 6-month follow-ups, 20 incisors belonging to 12 subjects aged between 12-24 months at the time of intrusion exhibited pulpal necrosis. The highest rate of total spontaneous re-eruption occurred in incisors intruded at 12-24 months. The likelihood of spontaneous re-eruption decreased with the child's age. A significant correlation between mobility at clinical follow-up and developmental disorders in permanent teeth was found, whereas a statistical correlation between age of patient at the time of trauma and sequelae was not pointed out, even if 17 primary incisors intruded at 12-24 months did not develop an arrest of root formation. Conclusion: The most traumatic intrusions in primary dentition occurs between 12 and 24 months of age, the most common cause being fall while walking. Intruded incisors with moderate mobility developed enamel hypoplasia and ectopic eruption. There was no significant correlation between age at the time of intrusion and type of subsequent developmental disturbances.Caprioglio, A.; Salone, G.S; Mangano, C.; Caprioglio, C.; Caprioglio, D.Caprioglio, Alberto; Salone, G.

[Supernumerary teeth in the deciduous dentition].

The Authors presented sovrannumeraries (S) teeth in primary dentition, and the pedodontic, surgical and orthodontic problems. Semeiotics signs, and X Ray suggested, are described. All the types of S. teeth are showed: supplementaries, conoides, tuberculates and infundibuliformes. For every type characteristics, problems and surgical timing are described. Tuberculates and infundibuliformes teeth are the most dangerous for the permanent teeth interrupted: eruption delay, dilacerations, impactions, fusion, follicles, diseases, are reported. The direction of the growth of S. teeth must be analyzed. If the direction is external the timing of surgery is very important. Finally the Authors emphasized the role of cooperation of pedodontist, with oral surgeon and orthodontist for to obtain good results

[Dynamic changes in nasal resistance and cephalometric parameters in mouth breathing children two years after adenotonsillectomy].

The Authors show the results of a research after 2 years from adenotonsillectomy or adenoidectomy. The comparison between the results after 6 and 24 months shows there are no differences among these results
