It is undeniable that the advent of extra-alveolar mini-implants for anchorage purposes has revolutionized the field of Orthodontics. This case report sheds light on an innovative anchorage plan using TADs, to carry out treatment for a 15-year-old female patient. The patient reported to the clinic with a chief complaint of rotated second premolars, crowding, and a deep bite. On examination, it was seen that the patient had a Class I skeletal pattern, Class II subdivision molar relationship, 90-degree maxillary second premolar rotations, crowding in both the arches, and a deep bite. In this case, the clinicians decided to use TADs for premolar derotation as it not only provides a pure rotational couple without any deleterious effects on the adjacent teeth but also helps shorten the overall treatment time. The total treatment time for this case was 10 months.

Cleft lip and Palate (CLP) is the most common craniofacial condition. Management of patients with clefts often requires multi-disciplinary rehabilitation of the orofacial structures. This case report demonstrates the multi-disciplinary management of an adult with a cleft lip and palate, highlighting the benefits of 3-Dimensional (3D) diagnosis, treatment planning and clinical execution of the plan. The patient presented with a severe maxillary deficiency, mandibular asymmetry, and congenitally missing maxillary right central and lateral incisors. This case report demonstrates an alternative approach for the management of cases with ipsilateral missing central and lateral incisors. The maxillary right canine substituted the congenitally missing maxillary right central incisor, while the maxillary right first premolar substituted the congenitally missing right lateral incisor, eliminating the need for prosthetic replacements. Total treatment time was 19 months, and the burden of care for the patient was minimized. An acceptable occlusion was achieved, and the patient’s esthetics improved significantly at the end of treatment. More importantly, the patient reported a marked improvement in his quality of life.

Background: Dental anomalies usually lead to complicated decisions having to be made in terms of the orthodontic treatment of permanent dentition; tooth rotation is the most common of these irregularities. The prevalence rate of this phenomenon is 2.1–5.1% in patients who have not received orthodontic treatment. Purpose: This case report aimed to manage the complete bilateral rotation of maxillary canines with couple force by using a Nance appliance modification. Case: A 17-year-old male patient came in wanting to straighten his teeth. He complained about his bilateral canines, which were not in a normal position. There was an impacted left maxillary second premolar and an ectopically erupted right maxillary first premolar. He also had protrusions in the upper and lower anterior teeth and crowding in the lower anterior teeth as well as upper and lower midline deviations. Case Management: A clinical examination showed a class I relationship between the dental and cephalometry measurements and highlighted a class I skeletal pattern. The upper right first premolar was extracted and the left second premolar had undergone an odontectomy to allay protrusion and correct crowding. Bilaterally rotated upper canines were derotated using a modified Nance appliance and an elastomeric chain with couple force. Conclusion: The success of the orthodontic treatment was influenced by the specific nature of the patient’s dental and medical history, extraoral and intraoral examination, diagnosis and treatment planning, which was followed by a systematic approach to treatment. The Nance appliance modification reduced the total treatment time by achieving controlled anchorage and derotation of the canines.

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.

The feasibility of inhibiting polyphenoloxidase from apple and pear by pulsed electric field processing was evaluated. These treatments significantly lowered polyphenoloxidase activity of enzyme extracts from apple ( Golden deliciousvar.) and pear ( Blanquillavar.). Exponential decay pulses were generated by a laboratory scale electric pulse generator and applied in bipolar mode. Pulse duration was 0.02 ms and electric field intensities were up to 24.6 kV/cm. The temperature of samples never exceeded 15 ºC during pulsed electric field processing treatments. Polyphenoloxidase activities were reduced up to 3.15% and 38.0% initial value in apple extract at 24.6 kV/cm and pear extract at 22.3 kV/cm both for 6 ms total treatment time, respectively. Apple and pear polyphenoloxidase exposed to pulsed electric field processing diminishes their activities following first order kinetics. Rate constants ranged from 132 to 440 ms 1 for apple polyphenoloxidase, whereas for pear 1 and changed exponentially with the applied electric field intensity. Residual polyphenoloxidase activity was correlated to energy density by an exponential decay model.
