A slight alteration of the enamel surface is inevitable upon debonding of orthodontic brackets, adhesive removal, and finishing/polishing. The aim of this in vitro study was to compare two adhesives and three polishing methods by measuring enamel surface roughness using confocal laser scanning microscopy (CLSM). Brackets were bonded on 42 extracted human premolars using Transbond XT (Transbond group) or Fuji Ortho (Fuji group). After debracketing, adhesives were removed with a tungsten carbide bur, and surfaces were polished using Sof-Lex discs, a rotary brush with a prophylactic paste (Depural), or a prophylactic cup with two polishing pastes (n = 7 in each subgroup). Surface roughness (Sa, Sku, Sq, and Sz) was measured using CLSM and compared before treatment (T1), after debracketing and adhesive removal (T2), and after polishing (T3). The data were statistically analyzed using the Mann-Whitney U and Kruskal-Wallis tests with Bonferroni correction. The time required for adhesive removal was measured and compared using a two-sample t-test. Surface roughness at T2 increased compared to T1, but the difference was significant only for the Fuji group (p < 0.01). The time required to remove Transbond XT (94.1 ± 6.8 s) was significantly higher compared to Fuji (72.1 ± 5.9 s, p < 0.0001). Polishing with Sof-Lex discs resulted in lower surface roughness compared to T1 (p = 0.018). Using Depural and polishing pastes showed no significant difference in surface roughness compared to T1, except for a significant decrease in Sa and Sq for Transbond (p = 0.043) and in Sku for Fuji (p = 0.018) after polishing with Depural. In conclusion, the removal of Transbond took significantly longer, but there were fewer residues of composite resin on the enamel surface. Sof-Lex discs decreased enamel roughness, whereas enamel morphology and roughness were similar to the pre-treatment state after polishing with polishing pastes.

Aim: The study sought the answer to the question whether the psychological profile of patients after orthognathic surgery changed. Using a structured questionnaire, we measured the change in self-confidence and extroversion, and assessed the relationship between the change and the patients’ sex and age. We also assessed the most often cited pros and cons of orthognathic surgeries. The respondents also informed about whether they would undergo the surgery again. Material and method: The study follows from the study of MDDr. Borunská (2015) who used a questionnaire to assess the differences in self-confidence in patients without any therapy/ with orthodontic therapy/ after orthognathic surgery. In our study we worked with the sample of patients indicated for orthognathic surgery. The original sample included 88 patients who filled in the questionnaire of MDDr. Borunská 4 years ago. 30 patients underwent orthognathic surgery and 21 of them agreed to take part in our study. They were repeatedly sent the structured questionnaire, and the resulting scores of different values of the Rosenberg self-esteem test (change in self-esteem) and the NEO test (change in extroversion) were compared. Results: The comparison of difference in the Rosenberg test before and after surgery did not show significant change in the score. The comparison of the NEO test (extraversion values) proved statistically significant decrease of values. We also assessed the potential relationship between results of the Rosenberg and the NEO tests and patients’ sex. The comparison proved only decreased values in women. We also studied the correlation between the patients’ age and change of self-esteem. Statistically significant increase in values was found only in extroversion – the older the patient the higher value of extroversion. The most often cited cons of the surgery were postoperative pain (7 patients), numbness of chin and lower lip (6), liquid food and diet following the surgery (4), postoperative oedema (2). The most often cited benefits included appearance (including face profile) (12 patients), better occlusion (7), higher self-esteem (5), better socialization (2). 18 respondents would undergo the surgery again, 3 would not. Conclusion: There were not statistically significant changes in the respondents’ self-esteem. The relationship between patients’ selfesteem and their age was not statistically proved. In case of extroversion we can see the trend – the older the patients the more extrovert they are. The relationship between the change in self-esteem and the patients’ sex was not proved. The only statistically significant difference was found for the values of extraversion in women (the extraversion decreased after the surgery). The pros of orthognathic surgery: improved appearance (including face profile) (55% of respondents), improved occlusion (33%), increased self-esteem (24%), better social life and establishing relationships (10%). The cons of orthognathic surgery: postoperative pain (33%), numbness of chin and lower lip (29%), postoperative discomfort when eating (19%), and postoperative oedema (10%). 86% of the patients would undergo the surgery again, 14% would not. Statistically significant relationship between self-esteem and the most frequently reported pros and cons of orthognathic surgeries was not proved.
Aims: The aim of the presented study was to verify the process of measurement of transversal dimensions of jaws that could be used in orthodontic practice. Another objective was to measure transverse deficiencies (i.e. the difference between skeletal width of the lower and upper jaws, and all first molars inclination) with CBCT in patients with skeletal Class I. We also wanted to find out whether the values are different in patients with various vertical parameters. Material and method: The sample included 152 patients – 24 of those with unilateral crossbite and 9 with bilateral crossbite. All scans were made with NewTom VGi-Evo (QR srl., Verona, Italy) with FOV 16 x 16 cm. The sample comprised boys and girls aged approx.14 without prior orthodontic treatment, with skeletal Class I according to ANB angle and WITS and with Angle Class I in molars. A standard cephalometric analysis in graphic module of PC Dent (CompuGroup Medical, Czech Republic) from lateral cephalogram made from CBCT scan was carried out. NSML and proportion of anterior and posterior facial height (SGo/NMe x 100) values were recorded. From CBCT scans linear and angular parameters were taken to determine dental and skeletal transverse deficiency. Results: There was proved a statistically significant difference between boys and girls only in the normodivergent group in the angle of lower first molars. The statistically significant difference in the angle of lower molars was found in hyperdivergent group. The individual groups (A, B, C, D, E) show statistically significant differences in the values of vestibulooral inclination of upper molars, in skeletal width of the lower jaw, and in the difference of skeletal bases width. Conclusion: Discrepancy in the transversal dimensions of jaws is not related only to lateral crossbite but it can be found in patients with relatively normal widths. Vestibulooral inclinations of first molars made the compensation of skeletal problem underlying transverse deficiency possible.

INTRODUCTION: High-quality scientific and technological advancements are necessary if quality improvement is to be achieved in orthodontic treatment. However, suboptimal research uptake in clinical practice and innovation adoption patterns that are not consistent with scientific evidence suggest that a better understanding of the adoption behavior of clinicians is needed. This research aimed to explore the factors that influence orthodontists to adopt innovations into practice. METHODS: This was a qualitative study in which 9 semistructured in-depth interviews were conducted with orthodontists and third-year orthodontic residents. The interviews were digitally recorded, and field notes were taken. Data were professionally transcribed verbatim and deidentified. Thematic analysis was used to inductively generate codes and subsequent themes. This study was reported according to the consolidated criteria for reporting qualitative studies checklist. RESULTS: Six main themes emerged as facilitators or barriers to adoption. In addition, a sequence of events that took place from knowledge encounter through to implementation was described. Factors influencing adoption included: the perceived state of one's current practice; features of the encounter; attributes of the innovation; clinician's personality traits; practice management; and external influences relating to the professional community, patients, and marketing pressures. CONCLUSIONS: The study provides an insight into what orthodontists consider in their decisions to adopt new knowledge into clinical practice. The findings can help clinicians navigate decision making around innovation adoption by increasing awareness of the factors that influence this process to ensure that switching practice leads to quality improvement.

Cíl: Cílem studie bylo vyhodnotit harmonii obličeje pacientů po ortognátní operaci několika cílovými skupinami hodnotitelů, kteří jsou odborníky v oboru zubního lékařství. Dalším cílem bylo zjistit morfologické rysy obličejů pacientů po ortognátní operaci, které hodnotitelé považují za problematické. Metoda: Vytvořili jsme on-line dotazník obsahující složené fotografie vytvořené ze 4 fotografií 30 osob vytvořených po léčbě: 15 pacientů (9 mužů, 6 žen, průměrný věk 29,7 let), kteří prodělali kombinaci ortodontické a chirurgické léčby (skupina A) a 15 pacientů (6 mužů, 9 žen, průměrný věk 26,7 let), kteří prodělali pouze ortodontickou léčbu (skupina B). Morfologické rysy obličejů a harmonie tváře byly hodnoceny na škále o 10 bodech a posuzovány skupinou 89 hodnotitelů, kteří byli rozděleni podle pohlaví, věku a vzdělání. Rozdíly mezi skupinami hodnotitelů byly statisticky vyhodnoceny. Výsledky: Ze všech posuzovatelů se jevila jako nejkritičtější skupina ortodontistů, nicméně rozdíly mezi jednotlivými skupinami nebyly významné. Ženy byly kritičtější než muži (p = 0,009), nejkritičtější ze všech věkových skupin byla skupina nejstarších hodnotitelů (nad 61 let) (p = 0,021). Pacienti po maxilofaciální operaci byli hodnoceni jako významně méně harmoničtí, o 0,29 bodů méně než průměrné skóre (p = 0,001). Asymetrie obličeje (r = -0,524, p = 0,045) se ukázala jako významný prediktor nižšího skóre obličejové harmonie u chirurgických pacientů, u pacientů, kteří operaci neprodělali pak asymetrie obličeje (r = - 0,672, p = 0,06) a konkávní profil (r = - 0,619, p = 0,014). Závěr: Pacienti po ortognátní operaci se ve srovnání s těmi, kteří nepodstoupili operaci, jeví jako méně harmoničtí. Zdá se, že reziduální obličejová asymetrie je významným faktorem obličejové estetiky, který snižuje celkové hodnocení harmonie obličeje.
Objective: The aim of the study was to evaluate the facial harmony of patients after orthognathic surgery by several target groups of evaluators who are involved with the dental profession. Another aim was to identify common morphological traits on faces of patients after orthognathic surgery, that the evaluators assess as problematic. Methods: An online questionnaire was formed containing photo composites made up from 4 post-treatment photographs of 30 individuals: 15 patients (9 male,6 female, mean age 29.7 years) that underwent combined orthodontic, orthognathic surgery treatment (Group A) and 15 patients (6 males, 9 females, mean age 26.7 years) that underwent orthodontic treatment only (Group B). Facial morphological traits were evaluated and facial harmony was recorded on a 10-point scale and assessed by a panel of 89 evaluators who were stratified to gender, age and profession education. Differences between groups of evaluators were assessed statistically. Results: Orthodontists were the most critical group of all assessors, however the difference between groups was not significant. Women appeared more critical than men (p = 0.009), the oldest group (above 61 years old) was the most critical (p = 0.021) of all age groups. Patients after maxillofacial surgery were evaluated as significantly less harmonious by 0.29 points lower of mean score (p = 0.001). Facial asymmetry (r = -0.524, p = 0.045) was found to be a significant predictor of lower facial harmony scores in surgical patients, and facial asymmetry (r = -0.672, p = 0.06) and concave profile (r = -0.619, p = 0.014) in non surgical patients. Conclusion: Orthognathic surgery patients appear less harmonious when compared with non surgical patients. Residual facial asymmetry appears to be an important factor of facial esthetics, decreasing the overall rating of facial harmony.
