The aim of this study was to analyze factors affecting treatment times in patients treated with the surgery-first approach (SFA) for orthognathic surgery. Fifty skeletal class III patients who had undergone SFA bimaxillary orthognathic surgery were enrolled. Retrospective chart reviews and analysis of 3D CT and digitally scanned casts were conducted to assess the total treatment time. Statistical analysis was then performed with multiple study variables. Longer treatment times were required for patients with severe maxillary or mandibular teeth crowding (p = 0.009), a preoperative anterior open bite (p = 0.021), and those undergoing orthodontic extractions (p < 0.001). Longer treatment times were also observed when setting surgical occlusion in the postoperative anterior open bite (p = 0.007) and in patients with postoperative dental midline deviation (p < 0.001) and transverse maxillary deficiencies (p = 0.035). Treatment times were shorter when a class I molar key was formed in the surgical occlusion setup (p = 0.002) and in bilateral anterior and posterior occlusion with a minimum of four contact points (p < 0.001). The number of contact points, the number of extracted teeth, and postoperative midline deviation were identified as significant predictors. These results suggest that proper patient selection is important when considering SFA and that surgeons can reduce total treatment time with an appropriate surgical occlusion setup.

ABSTRACT Aim This article is intended to provide an overview of the Surgery First Approach (SFA) mainly including case selection, diagnosis, treatment protocols, success rate and the potential problems encountered. Background The most important indication of the need for orthognathic surgery is usually the psychosocial effect resulting from the unaesthetic appearance of a dentofacial deformity. The conventional approach in treatment of such deformities till today has been an orthodontics-first approach. Review Results Available evidence suggest that both the SFA and the conventional approach had similar outcomes in dentofacial relationships however the relapse tendency was greater with the SFA but the total treatment duration was substantially shorter. Conclusion SFA treats facial aesthetics (and the skeletal malrelation) first and then occlusion, i.e. orthognathic surgery antecedes the orthodontic therapy. The concept of this technique is to utilize orthognathic surgery to eliminate the displeasing pre-surgical facial profile and promptly accomplish facial aesthetic enhancement that is usually the patient's chief complaint at the beginning of the treatment. SFA also facilitates accelerated orthodontic tooth movement thus reducing the length of post-surgical orthodontic therapy. Clinical Significance The optimal esthetic and functional results, significant reduction in total treatment time and high patient satisfaction led us to the postulation that SFA may represent a reasonable, cost-effective method to manage skeletal malocclusions in selected cases and that it has the potential to become a standard approach to orthognathic surgery in the future.

Background: Vital tooth whitening has become an integral part of esthetic dentistry and remains one of the safest and most economic options today to improve dental esthetics without removing tooth structure. The tooth whitening materials have evolved into three categories: dentist-prescribed/dispensed (in office and patient home-use), and over-thecounter purchased and applied by patients. Objective: This review outlines the latest advances in dentist prescribed vital teeth whitening techniques, effects on tooth structure, soft tissues, and dental restoratives. Areas requiring additional research are also discussed. Methods: Electronic and manual literature search was conducted for key words such as tooth bleaching, and dental bleaching techniques using PubMed/MEDLINE, followed by manual selection of the studies that included whitening procedures in vital teeth. Results: The two main whitening agents are carbamide peroxide (CP) and hydrogen peroxide (HP or H2O2) whose concentration, duration of contact, and total treatment time can alter results. In addition, factors including the type of stain, and age of patient can affect results. Although whitening agents can affect tooth structure, restorative materials, and gingival tissues, the changes are temporary or can be treated using minimally invasive techniques. Conclusion: Areas requiring further research include the actual mechanism of whitening, its effect on tooth structure and restorative materials, and the development of an easy method to quantitate the degree of whitening in the dental office.

Objective To evaluate the efficacy of the figure-of-eight (FOE) suture technique in the treatment of tunnel bleeding after femoral artery puncture compared with manual compression (MC). Methods This prospective, randomized, controlled study enrolled patients that had received transfemoral coronary artery angiography or percutaneous coronary intervention and then developed tunnel bleeding. They were randomly assigned into two groups: FOE suture group (ES group) and manual compression group (MC group). Total treatment time, performance frequency, performance time, rate of deep vein thrombosis (DVT) and in-hospital time after the procedure were compared. Results A total of 152 patients were enrolled in the study (ES group, n = 63; MC group, n = 89). Compared with the MC group, the total treatment time (mean ± SD: ES 22.3 ± 5.4 h versus MC 26.8 ± 6.8 h), performance frequency (mean ± SD: ES 2.1 ± 0.7 versus MC 2.6 ± 1.1), performance time (mean ± SD: ES 8.9 ± 2.5 min versus MC 12.3 ± 4.1 min), in-hospital time after the procedure (mean ± SD: ES 3.5 ± 1.2 days versus MC 4.8 ± 2.1 days) and DVT rate (ES 0.0% versus MC 6.7%) were significantly lower in the ES group. Conclusion The FOE suture technique effectively treated tunnel bleeding after femoral artery puncture.

This case report describes the orthodontic treatment of an 18-year-old male patient who presented with Straight profile; tongue thrust habit, proclined upper incisors, generalised spacing in upper and lower arches, Katz's class II premolar relation unilaterally, class II canine relation unilaterally with increased overjet and overbite. A butterfly system was used in the treatment combined with frictionless biomechanics in the initial stage of treatment followed by continuous arch mechanics in the later part of treatment. A tongued crib was used to stop the tongue thrust habit along with one elastic swallow exercise. Micro-implant anchorage was used unilaterally in the upper arch for retraction of the entire segment and correction of the unilateral class II canine and premolar relationship. To avoid a dished in profile, a non-extraction treatment was executed. Final corrections of distally tipped canines were achieved using conventional Begg’s  uprighting auxiliaries in the vertical slots of butterfly system in the finishing stage. The case was finished using bite settling elastics. Total treatment time was 1 year 2 months. Aesthetic and functional goals were achieved satisfactorily with proper selection of biomechanics.

Purpose To determine whether increased duration of radiation therapy (RT) and overall treatment (RX) time has a detrimental effect in anal cancer. Patients and Methods Data from Radiation Therapy Oncology Group (RTOG) 87-04 and RTOG 98-11 trials were combined to form three treatment groups: RT/fluorouracil (FU)/mitomycin (n = 472), RT/FU/cisplatin (n = 320), and RT/FU (n = 145). Cox proportional hazards models were used with the following variables: RT duration, RT intensity, RX duration, treatment group, age, sex, Karnofsky performance score (KPS), T stage, N stage, and RT dose. Results In the univariate analysis, there was a significant association between RX duration and colostomy failure (CF; hazard ratio [HR] = 1.51; 95% CI, 1.07 to 2.14; P = .02), local failure (HR = 1.52; 95% CI, 1.14 to 2.03; P = .005), locoregional failure (HR = 1.51; 95% CI, 1.15 to 1.98; P = .003), and time to failure (HR = 1.40; 95% CI, 1.10 to 1.79; P = .007). The significance of RX duration was maintained after adjusting for treatment group. In multivariate modeling there was a trend toward an association between RX duration and CF (HR = 1.57; 95% CI, 0.98 to 2.50; P = .06) and a statistically significant association with local failure (HR = 1.96; 95% CI, 1.34 to 2.87; P = .0006). Age, sex, KPS, T stage, N stage, and RT dose, but not RT duration, RT intensity, or RX duration, were found to be statistically significant predictors of OS and colostomy-free survival. Conclusion Total treatment time, but not duration of radiation therapy, seems to have a detrimental effect on local failure and colostomy rate in anal cancer. Induction chemotherapy may contribute to local failure by increasing total treatment time.
