ABSTRACT
PURPOSE: The leading concern of orthodontic patients is prolonged treatment with fixed appliances and demand speedy treatment from the orthodontists. Piezocision is a relatively innovative, safe and reliable technique of corticotomy in the domain of surgically-accelerated orthodontic treatment. Our aim was to compare the efficiency of piezo corticotomy (piezocision) and conventional bur in rapid orthodontic tooth movement (OTM). SUBJECTS AND METHOD: The study employed a randomized, double-blind, split-mouth design. 24 subjects with Class II div 1 malocclusion were randomly assigned to the two interventions, viz; piezo and bur group. The primary parameters evaluated were the rate and amount of tooth movement and total treatment time required for canine retraction. Additionally, the duration of surgery and postoperative complications were also evaluated. OBSERVATIONS AND RESULTS: Rate and amount of tooth movement were significantly higher with reduction in total treatment time in piezo compared to bur group. The duration of surgery was significantly longer in piezo group with no significant difference observed in post-operative complications. CONCLUSION: Piezo-guided corticotomy was effective in providing rapid OTM with profound reduction in total treatment time and may be proposed as a suitable adjuvant to conventional corticotomy having comparable post-operative complications.
ABSTRACT
BACKGROUND: Immersion media such as ophthalmic irrigation solution, eye lubricant solution, and neutral soap solution will be the best, which will help in the longevity as well as the color stability of ocular prostheses. AIM: The aim of this study was to evaluate and compare color stability of ocular prosthesis after immersion in three different immersion media. MATERIALS AND METHODS: A total of 90 samples of scleral acrylic resin were prepared, which were painted with natural dry earth pigment NEAS and then were divided into three groups. These samples were checked before and after immersion in respective media after 8 weeks. To assess the color change, a spectrophotometry test was performed and the results were statistically analyzed by one-way analysis of variance and post hoc Tukey's test. RESULTS: Among all the three groups, the samples immersed in neutral soap solution proved to be most color stable, followed by eye lubricant solution, and the least color stable among the three was ophthalmic irrigating solution. CONCLUSION: The neutral soap solution proved to be the most color stable.
ABSTRACT
Foreign body of aerodigestive tract is one of the most common emergency which all the otolaryngologists do come across in the pediatric patients. Among the airway and digestive tract foreign bodies, airway foreign bodies always possess major risk. Only 47% cases will give a probable positive history. Most of the time the airway foreign bodies are radiolucent. Apart from the indirect signs like hyperinflation, collapse or pneumothorax there are no direct evidences regarding the type and number of foreign bodies on radiographs. The chances of having multiple foreign bodies in the same bronchus or in both the bronchi are not remote. Babies presenting with foreign bodies in bilateral bronchus have graver prognosis than the babies with unilateral foreign bodies. Here we want to share our experience in managing 7 cases of bilateral foreign body bronchus.
ABSTRACT
Fracture of the angle of the mandible accounts for nearly one-third of all fractures involved. The presence of lower third molar increases the risk of fracture in angle region. The third molar acts as an area of weakness leading to fracture lines passing medially, distally, and occasionally through it. Angle fracture leads to the mobility of the third molar and sometimes its displacement. Third molars maintain its position in favorable fracture and can be displaced in unfavorable fractures. Displacement of lower third molar in lateral pharyngeal space due to mandibular fracture is not seen commonly. To our knowledge, this is the first reported incidence of displacement of the third molar into lateral pharyngeal space in a case of mandibular fracture.
ABSTRACT
Masseter muscle hypertrophy is a rare condition of idiopathic cause. It clinically presents as an enlargement of one or both masseter muscles. Most patients complain of facial asymmetry; however, symptoms such as trismus, protrusion, and bruxism may also occur. Several treatment options reported for masseter hypertrophy are present, which range from simple pharmacotherapy to more invasive surgical reduction. Keloid scar with unilateral masseter hypertrophy is a rarely seen in clinical practice. This paper reports a case of unilateral masseter hypertrophy with keloid scar in the angle of the mandible for which surgical treatment was rendered to the patient by using a single approach.
