Case Reports of Enamel Microabrasion Associated with At-home Dental Bleaching After Orthodontic Bracket Removal.

Adequate removal of residual bonded materials from the enamel surface after orthodontic bracket debonding is critical, since any remaining composite may compromise enamel surface morphology and esthetics. The following clinical case reports present the association of at-home dental bleaching using 10% carbamide peroxide and the removal of residual bonded material using a super fine, tapered diamond bur followed by the use of an enamel microabrasion product after orthodontic bracket debonding. The proposed treatment considerably improved the esthetics and successfully removed the grooves created during the removal of the bonding composite, resulting in a smooth enamel surface.

Enamel Microabrasion and Dental Bleaching on Teeth Presenting Severe-pitted Enamel Fluorosis: A Case Report.

The present clinical case report describes the clinical steps of enamel microabrasion associated with dental bleaching to restore severely-pitted fluorosed teeth. The process of removing the fluorotic superficial stains started by using macroabrasion with a water-cooled fine tapered 3195 FF diamond bur. Rubber dam isolation of the operative field was used to remove the remaining enamel stains and superficial irregularities with the Opalustre microabrasive compound (6.6% hydrochloric acid associated with silicon carbide particles) followed by polishing using fluoridated paste and subsequent 2% neutral fluoride gel topical application. After one month, dental bleaching was performed using 10% carbamide peroxide in custom-formed acetate trays for two hours/day for 42 days. The association of enamel microabrasion with dental bleaching was effective for reestablishing the dental esthetics of a patient with severe dental fluorosis.

The impact of a cervical dysplasia diagnosis on individual cancer prevention habits over time: a bicentric case-control study.

PURPOSE: Annual cervical cancer screening is recommended in Germany as a part of the statutory preventive care. Abnormal results can provoke psychological distress and anxiety, compromising women's adherence. Little is known about how a cervical dysplasia impacts adherence follow-up visits and prevention habits over time. To optimize care strategies, this study aims to identify women at risk for nonadherence to follow-up visits after a screening event. METHODS: Between November 2015 and May 2017, participants with an abnormal Pap smear at the Heidelberg and Leipzig University Hospitals received a four-part questionnaire (sociodemographic data, PHQ-D, self-designed fear and prevention habit questions) at the first consultation (T1) and subsequently after 3 (T2) and 6 (T3) months; healthy controls completed the questionnaire at T1. RESULTS: 132 women with an abnormal Pap smear [with conization: S1 (n = 68, 51.5%), without intervention: S2 (n = 64, 48.5%)] and healthy controls (K, n = 101) generally adhered to gynecological checkups, except S1 6 months after the first diagnosis (S1/T3 - 0.47, signed rank p < 0.0005). Knowledge of primary prevention information, i.e., HPV vaccination, was significantly higher among K (K 58%, S1 29%, S2 44%, Chi-squared p = 0.01) as was vaccine uptake (K 39% versus S1/S2 7% and 17%, respectively, Chi-squared p = 0.0004). Fear of upcoming Pap smears rose significantly over time (S1/T1-S1/T2-S1/T3, Wilcoxon signed-rank test p < 0.001) and was higher among those with conization at T2 (Chi-square test, p = 0.01) and partially accompanied by panic disorders at T1 (Chi-square test p = 0.035). Realization of general preventive habits rose significantly among women without an operative procedure (S2) over the study. CONCLUSION: This study advances the understanding of non-participation in follow-up visits after a dysplasia diagnosis, identifying post-conization women as a special risk group for decreased adherence.

Home Dental Bleaching Monitored With Microelectronic Sensors to Record the Wearing Times of an Acetate Tray/Bleaching Product.

The present case study quantifies the clinical wearing time of an acetate tray/bleaching product during home dental bleaching. The patient was instructed to use a 10% carbamide peroxide gel for 6-8 hours each day for 20 days. The wearing time of the tray was measured by a microsensor from TheraMon microelectronic system (Sales Agency Gschladt, Hargelsberg, Austria) completely embedded in the tray so that the clinician would be informed as to the precise time the tray was placed in the mouth. Evaluation of the daily printout during dental bleaching demonstrated that the patient did not correctly follow the clinician's instructions as to the wearing time of the tray. Recording the wearing time of dental bleaching agents can be beneficial for both dental professional and patient to obtain a more effective treatment according to the patient's needs and expectations.

Assessment of two e-learning methods teaching undergraduate students cephalometry in orthodontics.

AIM: Cephalometry is important for orthodontic diagnosis and treatment planning and is part of the core curriculum for training dentists. Training involves identifying anatomical landmarks. The aim of this investigation was to assess whether e-learning improves learning efficiency; a programme specifically designed for this purpose was compared to commercially available software. METHODS: Thirty undergraduate students underwent traditional training of cephalometry consisting of lectures and tutorials. Tracing skills were tested immediately afterwards (T0). The students were then randomly allocated to three groups: 10 students served as control (CF); they were asked to improve their skills using the material provided so far. Ten students were given a program specifically designed for this study that was based on a power point presentation (PPT). The last group was given a commercially available program that included teaching elements (SW). The groups were tested at the end the six week training (T1). The test consisted of tracing 30 points on two radiographs and a point score improvement was calculated. The students were interviewed after the second test. RESULTS: Both e-learning groups improved more than the traditional group. Improvement scores were four for CF; 8.6 for PPT and 2.8 for SW. For PPT all participants improved and the student feedback was the best compared to the other groups. For the other groups some candidates worsened. CONCLUSIONS: Blended learning produced better learning outcomes compared to using a traditional teaching method alone. The easy to use Power Point based custom software produced better results than the commercially available software.

Maxillary expansion therapy with plates featuring a transverse screw: implications of patient compliance with wear-time and screw activation requirements.

OBJECTIVE: The goal of the present work was to determine the influence of screw activation rates and electronically tracked wear times on transverse maxillary expansion with removable orthodontic appliances. METHODS: In all, 28 patients were included in an open prospective observational study covering approximately 6 months of maxillary transverse expansion. In each of these patients, the maxillary plate appliance used for treatment was fitted with a wear-time sensor to document wear time for the duration of the study. Patients were instructed to activate the transverse expansion screw in their plate appliance by 0.2 mm/week. The resultant gap-width increases were monitored with a caliper over three follow-up appointments scheduled at 2-month intervals. RESULTS: Largely linear increases in gap width due to screw activation were only noted within the first 4 months of treatment. The mean increases in gap width fell short of the values that were anticipated after calculations. Longer daily wear times were, on average, associated with larger gap widths. CONCLUSION: Treatment can be objectively monitored by referring to wear-time tracking and by measuring increases in gap width, thus, ensuring that the appliance fits well. In this way, the process can be customized to serve individual needs and to better utilize the full potential of therapy.

Methods to evaluate compliance of patients with removable appliances-survey results.

OBJECTIVES: Are removable appliances still being routinely used in orthodontic offices? Which methods do clinicians use to assess compliance with wear requirements, and how effective are these methods considered to be? SUBJECTS AND METHODS: A questionnaire inquiring about types of treatment, methods of assessing patient compliance with removable appliances, and the perceived effectiveness of these methods was mailed to a sample of 375 members of the German Orthodontic Society ("Deutschen Gesellschaft für Kieferorthopädie", DGKFO). RESULTS: The rate of returned questionnaires was 29%. Almost all respondents (99%) indicated that they used removable appliances and reported having a "relatively high" proportion of patients currently undergoing such treatment. The most widely used methods of compliance assessment were questioning patients and parents (96%) and examining clinical parameters associated with the dentition and the appliance's fit (95-100%). While these parameters were considered "highly effective", questioning the patients and parents was regarded as "less effective" despite its frequent application. CONCLUSION: Removable appliances continue to be a standard method of orthodontic treatment. While patient compliance with wear requirements is mainly assessed via indirect clinical methods, the effectiveness of these parameters remains unclear.

Questionnaire study of electronic wear-time tracking as experienced by patients and parents during treatment with removable orthodontic appliances.

OBJECTIVE: To survey how patients and parents rate microelectronic wear-time tracking (TheraMon(®)) during treatment with removable orthodontic appliances. PATIENTS AND METHODS: A total of 125 patients with a mean age of 11.99 years whose treatment involved removable appliances with a built-in microsensor for wear-time documentation were enrolled in a questionnaire study addressing electronic wear-time tracking. Respondents included the patients and their parents. RESULTS: A total of 86% of the patients reported that the orthodontic appliance's comfort was unaffected by the installed sensor. A majority of respondents had a favorable impression of wear-time tracking. Printed wear-time documents from the clinician's computer were considered a "nice certificate of compliance" by 46% of patients, and 38% of them stated that they intended to improve their compliance when faced with a poor record. Indeed, 48% of parents believe that wear-time tracking can improve the therapeutic success, while 32% believe that it can reduce the duration of treatment. Around 10% of respondents felt that the sensors were unnecessary and not recommendable. CONCLUSION: These favorable ratings by patients and their parents may help future patients and users to decide for or against microelectronic wear-time tracking. Randomized studies are needed to demonstrate whether the sheer presence of a wear-time sensor stimulates compliance on its own.
