ABSTRACT
OBJECTIVES: Literature is poor of data about the occlusion in children affected by neurofibromatosis type 1 (NF1). This case-control study investigated the occlusal traits in a group of children with NF1. SETTING AND SAMPLE POPULATION: A hundred and fifteen children with NF1 were enrolled; non-NF1 controls were sequentially selected among subjects referred to the Pediatric Dentistry Department. MATERIAL AND METHODS: All patients underwent a clinical dental examination and a panoramic radiography. The following orthodontic variables were considered: molar relationship, overjet, overbite, cross-bite, scissor bite, and crowding/spacing. RESULTS: Class III molar relationship resulted significantly (p = 0.01) more common in children with NF1 than in the control group as well as the unilateral posterior cross-bite (p = 0.0017). Forty-three children with NF1 (37.3%) showed radiographic abnormalities; in one case, a plexiform neurofibroma was detected. CONCLUSIONS: An early orthodontic evaluation might be planned in the management of children with NF1 to prevent or decrease the need for extensive orthodontic interventions.

AIM: The scientific literature is poor of data concerning NF1-related oral manifestations in children. The purpose of this study was to investigate the oral findings in a group of children with NF1. MATERIALS AND METHODS: This study was designed as a clinical research. A total of 50 children affected by NF1 were enrolled. Non-NF1 controls were selected among subjects referred to the Paediatric Dentistry Department of the Dental Clinic at the University of Brescia, Italy. The craniofacial and all the dental examinations were carried out. The following parameters were investigated: dental caries, dental abnormalities, periodontal status, oral and perioral neurofibromas, orthodontic features, mandible and temporomandibular joint abnormalities. Statistics Unpaired Student's t test was calculated for Gaussian distributed variables; Fisher's test for non-Gaussian distributed binomial variables was used. The values inferior to p <0.05 (threshold) were considered significant for the study. RESULTS: Children with NF1 showed poorer oral hygiene conditions, more frequent Class III dental malocclusions and severe alterations of the mandible and the temporal mandibular joint, if compared with the control group. CONCLUSION: NF1 related-oral manifestations are evidenced also during childhood, even if some of the best known, like the neurofibromas, are not yet developed. It is important to keep a long-term follow-up to monitor the possible development of other oral lesions.

AIM: In dental trauma with severe periodontal tissue involvement, as dental avulsion and severe luxation, the splinting procedure requires the patient to maintain a scrupulous hygiene of the affected zone, so to allow an effective tissue healing. The aim of this study was to assess the effectiveness of a specific oral hygiene protocol in the treatment of patients with post-traumatic splinting, comparing the plaque indexes of dental hygienist-helped patients versus not helped. MATERIALS AND METHODS: This study was carried out on 82 selected patients with post-traumatic splinting due to traumatic avulsion and severe luxation. They were divided into 2 groups, comparable for age, sex, type of trauma and splinting. The group A patients underwent an oral hygiene protocol, managed by a dental hygienist, while the group B patients were followed without the help of the hygienist. Plaque indexes were observed and compared in all cases during 6 weeks-follow up. RESULTS: Our results showed that at the 6th week follow up the plaque indexes of dental hygienist-assisted traumatized patients were significantly (p=0.001) lower than those of not assisted patients. CONCLUSION: Therefore, the role of dental hygienists is essential in the management of dental trauma with periodontal damage, which needs specific oral hygiene protocols.

This case describes a patient with a traumatic crown fracture of an upper incisor, associated with a laceration wound in the lower lip, showing local oedema. While palpating the tissues of the lower lip we felt the presence of a foreign body. This was confirmed by a radiograph of the lip that showed a radiopaque material, being similar to the coronal fragment of the fractured incisor. It was successfully surgically removed and immediately reattached using a composite adhesive technique. At the follow-up of 1 year later the vitality test on the teeth was positive and neither one of the two traumatized teeth showed any sign of discoloration.
