Objectives: To determine compliance with oral hygiene instructions (OHI) of adolescents receiving two-arch fixed orthodontic treatment in a graduate orthodontic clinic and to identify predictive factors. Methods: Forty-one patients in a longitudinal pilot study were provided standardized OHI and assessed at baseline: before bonding (T1); 30 days after (T2), and 150 days after bonding (T3). Oral hygiene was measured using plaque and gingival indices. Compliance predictors were identified from questionnaires and patient records. Results: Good compliers increased from 10 at T1 to 29 at T3. Univariate analyses found perceived severity of malocclusion, school performance and parental marital status to be significant predictors. Multiple logistic regression identified having married parents and good school performance as significant predictors. Conclusions: In the sample studied, after initially worsening, compliance with OHI improved at five months after bonding. Adolescents with married parents and those reporting good academic performance in school were more likely to comply.

Dental anxiety is not typically associated with orthodontic treatment because of the lack of evoking stimuli (i.e., drills, needles). Its prevalence in orthodontic patients is unknown but reported anecdotally. This study aimed to assess the prevalence of and factors contributing to dental anxiety in future and current orthodontic patients. University dental clinics and private orthodontic office patients completed a questionnaire including the Modified Dental Anxiety Scale (MDAS), MDAS-Ortho (both scored 1-not anxious to 5-extremely anxious; sum score >15=dentally anxious), and list of concerns about orthodontic treatment. 675 patients participated (60.4% private practice; 64.3% female; 24.9% new patients; 85.5% aged 12-20 years). University clinic patients reported significantly higher MDAS and MDASO scores (p<0.05). 22.8% were dentally anxious and 18.7% anxious about orthodontic treatment, with concerns related to their relationship with the orthodontist, perceptions of orthodontic treatment and treatment factors. Results confirm dental anxiety in orthodontic patients and factors contributing to that anxiety.

As new adhesive products become available in restorative dentistry, investigating their potential application for orthodontic use is warranted. Vertise Flow (Kerr) is a self-adhering flowable resin and is being marketed for use as a sealant, porcelain repair and small class I restorations. It has potential for use as an orthodontic adhesive. Objective: Determine if Vertise Flow (Kerr) is suitable for bonding fixed orthodontic appliances to enamel, restorative resin composite and porcelain with minimal surface preparation. Methods: Shear Bond Strengths (SBS) from six (6) groups of fifteen (15) bonded stainless steel lingual buttons (Ormco) were obtained over three time points (24hr, 7 days, and 3 months). The six test groups were: 1.Vertise Flow to enamel (Tt) with coarse pumice debridement, 2. Transbond XT (3M, Unitek) to enamel (Tc) with phosphoric acid etching [control], 3.Vertise Flow to Herculite Ultra (Kerr) (Cc) with coarse pumice debridement, 4. Vertise Flow to Filtek Supreme Ultra (3M, ESPE) (Ct) with coarse pumice debridement, 5. Vertise Flow (Kerr) to porcelain (Pt) with diamond bur roughening, and 6. Transbond XT (3M Unitek) to porcelain (Pc) with hydrofluoric acid etching. Samples were stored in distilled water and incubated at 37C. The buttons were then debonded with a Zwick Universal Testing machine using a 10 kN load cell with a crosshead speed of 0.5mm/min. Debonded buttons were evaluated based on a modified Adhesive Remnant Index (ARI). Statistical assessment of the data was performed using parametric and non-parametric tests, with p<0.05 as the threshold for statistical significance. Results: The mean SBS obtained in all groups at each time point were >4MPa and varied between 8.69MPa and 27.44MPa. Statistical differences were found within the composite and porcelain groups at T1, and the enamel and composite groups at both T2 and T3. Nearly half of the sample (47.2%) achieved an ARI score of 5 (100% adhesive left on button base). Conclusion: Vertise Flow potentially provides clinically acceptable bond strengths to enamel, restorative resin composite and porcelain with minimal surface preparation. Furthermore, upon removal, minimal adhesive clean-up is required thus saving valuable chair time. Based on the results in this study, future in vivo investigation is suggested.
