ABSTRACT
AIM: To collect prospective information reported by parents regarding dental traumas occurring in children 6 months to 4 years of age, furthermore, to collect data on complications from the dental records. METHODS: The staff from the child health services distributed a questionnaire at the regular health check-up reviews for a number of age groups, i.e., 6, 12, 18, 24, 30, 36, and 42 months of age. The parents were to observe and register factors around dental trauma for the following 6-month period. The questionnaires (138) were returned, irrespective of any trauma having occurred or not. If a child was seeing a dentist (emergency visit), the diagnosis of trauma and later complications were collected from the dental records. RESULTS: There were 35 of 138 children experienced trauma (6-47 months of age). The half-year incidence of trauma in children 6 months to 4.0 years of age was between 12 and 48%. A total of 41 traumatic dental injuries (TDIs) were reported. Of these 24 occurred indoors. The most common reason for trauma was falling accidents. In 24 out of the 41 reported TDIs the children were not seen by a dentist in connection with the trauma. The reason was that the parents thought the trauma did not matter. CONCLUSIONS: The high incidence of TDIs reported in toddlers in this study indicates that there is an under-reporting of TDIs in previously reported studies. The research design used in the present study has an advantage and should be tested in further studies.

OBJECTIVE: The purpose of this study was to investigate whether a new self-tapping implant for a bone-anchored hearing aid (BAHA) had the same high frequency of osseointegration as previous implants requiring pre-tapping. METHOD: Over a three-year period, 144 consecutive implants were placed in the mastoid for BAHA and evaluated. RESULTS: Two implants were lost; both were of the self-tapping type. One was in an 11-year-old boy, who lost his implant six weeks after surgery when the BAHA was fitted. The other was in an elderly man, a heavy smoker with diabetes. Using Fisher's exact test, there was no significant difference between the two groups (p>0.30). CONCLUSION: Self-tapping implants facilitate surgery and shorten operating time. Over a short follow up, we did not find any significant difference; however, it is important to follow these implants over a longer time period.

This study was undertaken on 100 children aged 16 years or under intended for installation of osseointegrated implants. Of these, 76 had implants installed for bone-anchored hearing aids or prostheses. The main indication for implant installation was a bilateral ear malformation. Surgery was generally performed as a two-stage procedure with a healing time of 3 to 4 months in between. Available bone thickness was on average 2.5 mm, and lack of bone necessitated bone augmentation in 12 patients. Thirty-nine percent of implants were installed in contact with the dura, sigmoid sinus, or an air cell. Implant failures were 5.8% of 170 inserted fixtures. Adverse skin reactions appeared in 9.1% of patients over a 21-year follow-up period. Revision surgery was undertaken in 22% of patients because of appositional growth of the temporal bone. Of the 24 children considered but not found suitable for osseointegration surgery, plastic surgery was considered a better option, or growth of the temporal bone was awaited. It is concluded that the rate of implant failure is lower in children; the frequency of skin reactions is the same as in adults, but revision surgery is more common in young patients because of new bone formation. Our clinical experience supported by the data presented in this article suggests that the concept could be used with good functional and aesthetic results in children.

Nineteen patients previously treated with 52 implants for anchorage of craniofacial prostheses were subjected to implant stability measurements by means of resonance frequency analysis (RFA), six months to 15 years after implant placement. The resonance frequency (RF) of a transducer attached to the implant abutment was measured by using a frequency response analyser, a personal computer (PC) and dedicated software. Statistically significant higher RF values were seen for implants in the temporal bone as compared to implants in the nose and periorbital regions. There was a positive correlation with time since implant placement for the period from six months up to seven years. It was concluded that the preliminary results suggest that implant stability increases with time and that implants in temporal bone are more stable than implants in the bone in the nose and periorbital regions, probably reflecting differences in bone density.
