AIM:
To evaluate the use of Second Class Resolver (SCR), a new fixed orthopaedic appliance, for the treatment of skeletal Class II malocclusion in growing subjects.
MATERIALS AND METHODS:
Design Retrospective analysis. Forty subjects were treated with Second Class Resolver (SCR). The mean age was 8 years at the beginning of treatment and 10 years at the end of treatment. Digital cephalometric superimpositions on lateral radiographs taken at start and end of treatment were assessed. The cephalometric values were statistically analysed.
RESULTS:
Cephalometric analysis of changes during treatment shows reduction of ANB angle (mean 2°); reduction of Witts Index (mean 3 mm); reduction of Maxillo-Mandibular angle (MM) (mean 1°); reduction of SNA (angle mean 3°); reduction of gonial angle (mean 1.8°); increase of the mandibular branch length (mean 5 mm); increase of mandibular body (mean 2.9°).
CONCLUSION:
The Second Class Resolver can be beneficially used for the treatment of Class II malocclusion

No full textDNA damage repair and genetic polymorphisms: assessment of individual sensitivity and repair capacity
No full textPurpose: To study the repair capacity after X-ray irradiation in human peripheral blood cells of healthy subjects, in relation to their genotypes.
Methods and Materials: The peripheral blood of 50 healthy subjects was irradiated in vitro with 2Gy of X rays and the induced DNA damage was measured by Comet assay immediately after irradiation. DNA repair was detected by analyzing the cells at defined time intervals after the exposure. Furthermore, all subjects were genotyped for XRCC1, OGG1, and XPC genes.
Results: After X-ray irradiation, persons bearing XRCC1 homozygous variant (codon 399) genotype exhibited significantly lower Tail DNA values than those bearing wild-type and heterozygous genotypes. These results are also confirmed at 30 and 60 min after irradiation. Furthermore, XPC heterozygous subjects (variant codon 939) showed lower residual DNA damage 60 min after irradiation compared with wild-type and homozygous genotypes.
Conclusion: The results of the present study show that polymorphisms in DNA repair genes could influence individual DNA repair capacity. (c) 2006 Elsevier Inc
