Book Description
The European Register of Cleft Lip and Palate Services will be produced as a result of the concerted action project: Standards of Care for Cleft Lip and Palate in Europe: EUROCLEFT funded by the European Commision under its BIOMED II and INCO COPERNICUS programmes. The project, aimed at developing a network of cleft care teams across Europe, ran for three years between 1996 and 1999 and aimed broadly to improve the effectiveness and efficiency of care for European children with clefts of the lip and/or palate. Clefts of the lip and/or palate are birth defects affecting 1:500 live births. Successful rehabilitation requires a complex multidisciplinary mix of services.

Book Description
Abstract: Introduction: The object of this research was to evaluate the reliability and validity of Peer Assessment Rating (PAR) index scores derived from computerized digital models. Computer based digital orthodontic models have been shown to be valid and reliable when making measurements of tooth size and simple diagnoses of dental malocclusions. The validity and reliability of PAR scores from digital models and plaster models that have been previously scored and standardized for a calibration exercise for the PAR index have not been established. Methods: Ten examiners were trained to score digital and plaster models using the PAR index. Thirty standardized and previously scored plaster PAR models used in PAR calibration were digitized using digital study model technology. The plaster and digital calibration models were randomized and scored by the ten examiners. All measurements were repeated by all examiners at a second session. Results: Plaster and digital scores were compared to the gold standard PAR scores for validity. The Intraclass Correlation Coefficients (ICC) for plaster models ranged from 0.808-0.926. The mean ICC for plaster models was 0.891 with a 95% confidence interval (CI) of 0.829-0.940. The ICCs for digital models ranged from 0.846-0.922. The mean ICC for digital models was 0.878 with CI of 0.811-0.931. Intra-rater reliability was excellent for plaster (ICC =0.919) and for digital models (ICC= 0.905). Inter-rater reliability was also good for plaster (ICC=0.912) and digital models (ICC=0.883). Conclusions: The PAR index scores obtained from the digital and plaster calibration models were shown to be valid and reliable.

Book Description
Introduction: The purpose of this retrospective case-control study was to compare the treatment effectiveness and efficiency of the Invisalign system and conventional fixed appliances in treating orthodontic patients with mild to moderate malocclusion in a graduate orthodontic clinic. Methods: Using the peer assessment rating (PAR) index, we evaluated pretreatment and posttreatment records of 48 Invisalign patients and 48 fixed appliances patients. Those two groups of patients were controlled for general characteristics and initial severity of malocclusion. We analyzed treatment outcome, duration and improvement between the Invisalign and fixed appliances groups. Results: The average pretreatment PAR score (United Kingdom weighting) was 20.81 for Invisalign and 22.79 for fixed appliances (P = 1.0000). Posttreatment weighted PAR scores between Invisalign and fixed appliances were not statistically different (P = 0.7420). On average, Invisalign finished 5.7 months faster than fixed appliances (P = 0.0040). The weighted PAR score reduction with treatment was not statistically different between the Invisalign and fixed appliances groups (P = 0.4573). All cases in both groups had more than 30% reduction in PAR score. Logistic regression analysis indicates the odds of achieving "great improvement" in Invisalign group was only 0.329 times the odds of achieving “great improvement” in the fixed appliances group after controlling for age (P = 0.0150). Conclusions: Our data show that both Invisalign and fixed appliances were able to improve the malocclusion. Invisalign finished treatment faster than fixed appliances. However, it appears that Invisalign may not be as effective as fixed appliances in achieving "great improvement" in the malocclusion. This study might help clinicians to determine appropriate cases for Invisalign treatment.
