The records of 200 orthodontic patients accepted for treatment by the Orthodontic Department of the Bristol Dental Hospital in 1977 were compared with 200 taken on in 1985 in order to determine whether there had been any change in the proportion of referred cases requiring more complex procedures. Within each sample, cases were categorized as follows: (a) suitable for removable appliance treatment by an undergraduate or general practitioner; (b) requiring simple one arch fixed appliance treatment such as might he attempted by a general practitioner after a period of further training; (c) needing specialist treatment such as full multibracketed fixed appliances or orthognathic surgery. It was found that there had been no change in the proportions of simple and complex cases referred during the 8-year period although the proportion of patients now receiving complex treatment had increased greatly. Possible explanations and implications are discussed.

Decalcification of the teeth remains a problem during orthodontic treatment with fixed appliances. It has been suggested that bonding agents which release fluoride could supply it to the area of the tooth most at risk from decalcification. The aim of this study was to estimate uptake by enamel adjacent to a fluoride releasing bonding agent. Acid etch biopsies were used to estimate the concentration of fluoride in enamel adjacent to brackets bonded with Vitrabond® and Geristore®. Results indicate that there was a significant increase in the concentration of fluoride in enamel adjacent to Vitrabond®. The clinical significance of the increase in the concentration of fluoride adjacent to Vitrabond® and the mechanism by which fluoride moves from the material into the enamel remain unclear.

Abstract Background: This systematic review aimed to compare the pain discomfort levels between InvisalignⓇ aligners comparing with traditional fixed appliances at multiple time points, through Pain Visual Analog Scale (VAS). Methods: Four electronic databases (Pubmed, Medline, CENTRAL and Scholar) were searched up to February 2019. There were no restrictions on year and publication status. Randomized clinical trials (RCTs) and case-control studies comparing pain perception through VAS in patients treated with Invisalign aligners and with labial appliances were included. Risk of bias within and across studies was assessed using Cochrane tool and Newcastle-Ottawa Scale (NOS) approach. Random-effects meta-analysis were conducted. VAS score at 1, 3 and 7 days, and analgesic consumption was collected. Pairwise and Binary Random-Effects Meta-analyses were used to synthesize available data. Results: At the initial search, a total of 87 articles were retrieved. Following the review protocol, 4 articles met the inclusion criteria and were included, with a total of 214 participants (139 females, 75 males). All studies were considered of high methodological quality. The results demonstrate that Invisalign aligners seems to be associated with significantly less pain than fixed appliances at 7 days after beginning the orthodontic treatment, although at 1 and 3 days the pain experience was similar in both orthodontics appliances. In regard to the type of material, SmartTrackⓇ aligners appear to give significantly better comfort for orthodontic patients than previous standard material, being that 3 days after appliance’s insertion this pain differential becomes significant, and this difference is more pronounced at 7 days. Conclusion: Patients treated with Invisalign experience less pain discomfort than those treated with fixed appliances and consume less analgesics. Overall, Invisalign promotes better pain and discomfort experience for the patient in the course of orthodontic treatment. Larger RCTs are needed to definitely demonstrate these findings throughout the orthodontic treatment.

Objective The objective of this study was to evaluate the craniofacial morphology of children with unilateral cleft lip and palate (UCLP) resulting from differing management protocols practiced in Prague from 1945 to 1976. Design The craniofacial morphologies of four groups of patients were compared. Two groups were assessed retrospectively (individuals born from 1945 to 1963), and two groups were followed on a longitudinal basis (individuals born from 1966 to 1976). Setting The study was conducted at the Cleft Lip and Palate Center at the Department of Plastic Surgery, Prague, which has a catchment area population of 6 million. Patients The subjects were a consecutive series of adult males (n = 84) who had complete UCLP without associated malformations. Interventions Patients born from 1945 to 1955 did not receive centralized orthodontic therapy. From 1945 to 1965, the alveolar process in the area of the cleft was not surgically repaired. Primary bone grafting was used for the group born from 1965 to 1972, and primary periosteoplasty was used in the subsequent period. Throughout the period covered by the study, the palate was operated on by pushback and pharyngeal flap surgery. From 1945 to 1965, the lip was repaired initially according to Veau, and later according to Tennison and Randall, and during this time, fixed appliances were used for orthodontic treatment. Results The results for the period from 1945 to 1955 are characterized by mandibular overclosure with anterior crossbite. Centralized orthodontic treatment in the later period improved sagittal jaw relations due to the posterior displacement of the mandible and an edge-to-edge bite was attained, but maxillary retrusion was unchanged. Primary bone grafting increased retrusion of the maxilla, which was compensated by further posterior displacement of the mandible. An edge-to-edge bite was also obtained. Primary periosteoplasty reduced maxillary retrusion, and the marked proclination of the upper dentoalveolar component with fixed appliances resulted in a positive overjet. It was no longer necessary to push the mandible back to the extent required in bone grafting. Conclusion Effective orthodontic treatment made the greatest contribution to improved facial development. It allowed compensation of maxillary retrusion by changes in the position of the mandible or by proclination of the upper dentoal-veolar component with fixed appliances. The applied surgical methods using primary bone grafting caused deterioration of the anterior growth of the maxilla.

Summary Background Self-applied and professional fluorides are key elements to limit caries-related side-effects during orthodontic treatment with fixed appliances. Objective To evaluate the effectiveness of a new fluoride varnish formula containing 1.5% ammonium fluoride in preventing white spot lesions (WSLs) in adolescents undergoing multi-bracket orthodontic treatment. Subjects and methods The study employed a randomized controlled triple-blinded design with two parallel arms. One hundred eighty-two healthy adolescents (12–18 years) referred to three orthodontic specialist clinics were eligible and consecutively enrolled. Informed consent was obtained from 166 patients and they were randomly allocated to a test or a placebo group (with aid of a computer program, generating sequence numbers in blocks of 15). In the test group, fluoride varnish was applied in a thin layer around the bracket base every sixth week during the orthodontic treatment, while patients in the placebo group received a varnish without fluoride. The intervention started at onset of the fixed appliances and continued until debonding. The endpoint was prevalence and severity of WSLs on the labial surfaces of the maxillary incisors, canines, and premolars as scored from high-resolution pre- and post-treatment digital photos with aid of a four-level score. Results One hundred forty-eight patients completed the trial, 75 in the test group and 73 in the placebo group (dropout rate 10.8%). The total prevalence of WSL’s on subject level after debonding was 41.8% in the test group and 43.8% in the placebo group. The number of patients exhibiting more severe lesions (score 3 + 4) was higher in the placebo group (P < 0.05); the absolute risk reduction was 14% and the number needed to treat was 7.1. Limitations The multicentre design with somewhat diverging routines at the different clinics may have increased risk for performance bias. No health-economic evaluation was carried out. Conclusions Regular applications of an ammonium fluoride varnish reduced the prevalence of advanced WSL during treatment with fixed orthodontic appliances. Clinical trial registration ClinicalTrials.gov (NCT03725020). Protocol The protocol was not published before trial commencement.
