The aim of this study was to compare the socio-demographic features and self-perception of parents concerning the malocclusion of their children with the orthodontist's opinion of normative orthodontic treatment need. The parents of 208 children (101 girls and 107 boys, between 9 and 18 years: mean 12.8 ± 2.5), who sought orthodontic treatment were asked to score the dental attractiveness of their children using the aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN). These scores were then compared with those of the orthodontist, who also scored the Dental Health Component (DHC) of the IOTN. The influence of the socio-demographic features of the parents on both the orthodontist- and parent-rated IOTN scores was assessed. The AC grade of the IOTN and patient characteristics were tested with the Spearman's correlation coefficient (rho). The difference between the two dependent variables (orthodontists' and parents' AC grade) was compared using Wilcoxon's test. A high need for orthodontic treatment was recorded in 74.0 per cent of the subjects. Although orthodontists rated 51.4 per cent of the patients as having a severe malocclusion on aesthetic grounds, only 33.6 per cent of parents rated their child malocclusion as severe. Although socio-demographic factors were not related to the parents' perception of malocclusion, they had an influence on orthodontic treatment need as assessed by the orthodontist. Parents, in this study population, rated their children's orthodontic treatment need less severely than the orthodontist regardless of their socio-demographic characteristics. Thus, orthodontists should involve parents in the orthodontic treatment decision-making process.

The microscrew implants did not demonstrate increased 1L-1beta levels during tooth movement. This supports the concept that microscrew implants might be useful as absolute anchorage devices.

Objective: To assess the effectiveness of 0.2% chlorhexidine gluconate mouth rinse on Streptococcus mutans and lactobacilli in orthodontic patients with fixed appliances. Materials and Methods: Twenty patients, aged 13-18, with fixed orthodontic appliances participated in the study. The levels of S mutans and lactobacilli in saliva samples were evaluated at four stages: at the beginning of the orthodontic treatment, at least 2 weeks after the bonding of brackets, 1 week after the introduction of 0.2% chlorhexidine gluconate mouth rinse, and at the fourth week. The changes in S mutans and lactobacilli levels were analyzed via Wilcoxon test. Results: Increases in bacterial levels of S mutans and lactobacilli were detected after the orthodontic appliances were bonded. A significant decrease in S mutans levels was observed 1 week after the introduction of chlorhexidine mouth rinse. Conclusions: An 0.2% chlorhexidine gluconate mouth rinse decreased S mutans levels, but had no effect on lactobacilli levels.

A 24-year-old man with a bilateral cleft lip and palate was treated by a multidisciplinary team composed of an orthodontist, plastic surgeon, and prosthodontist with assistance from an engineer. Before treatment, clinical photographs, dental casts, lateral and posteroanterior cephalograms, periapical and panoramic radiographs, and three-dimensional computed tomography (3D CT) images were obtained. He presented with a narrow and retrognathic maxilla with a 23-mm anterior open bite. Following maxillary expansion with rapid palatal expansion, a Le Fort I maxillary osteotomy was performed, and an internal distractor was placed. After a 5-day latency period, internal maxillary distraction was performed at a rate of 1 mm/day achieved by two activations per day. Cephalometric analysis showed a 7-mm maxillary advancement. Mandibular bilateral sagittal split osteotomy was also performed to close the open bite following maxillary distraction and a 3-month stabilization period. Finally, the treatment was completed with prosthetic rehabilitation. The changes in speech production were evaluated using an automatic speech recognition system.
