شکستگی تاج دندانهای قدامی کودکان به علل مختلف از جمله مواردی است که هر دندانپزشکی به دفعات با آن مواجه می گردد. این مطالعه در مورد شیوع شکستگی تاج دندانهای قدامی در دانش آموزان 14-7 ساله شهر تهران و عوامل وابسته به آن که عبارتند از جنس، سن، دندان صدمه دیده، فک و ناحیه مورد صدمه، میزان اوربایت (overbite)، میزان اورجت (overjet)، پوشش لب بالا و نوع شکستگی ساختمان تاج دندان انجام گرفت. در این مطالع...
سابقه و هدف: بتا تالاسمی ماژور یک اختلال خونی است که به علت تولید ناکافی هموگلوبین کار آمد و نیز عدم تعادل و تجمع نامناسب زنجیره های گلوبینی سبب بروز علائم بالینی می شود. خون سازی در استخوان های صورت می تواند سبب بروز تغییرات در صورت شده و در اصطلاح صورت آن ها شبیه موش خرما می شود. خون سازی در استخوان ماگزیلا سبب برجستگی ماگزیلا شده، می تواند سبب بروز مال اکلوژن در این بیماران شود . در مورد وضع...
Skeletal relationships in the sagittal plane do not always correspond with dental relationships. The aim of this study was to determine in which type of malocclusion the correlation between overjet and skeletal sagittal parameters assessed by lateral cephalogram analysis is the highest. The extent to which overjet can predict skeletal relationships in the sagittal plane was also assessed. Eight...
The aim of this study was to aggregate the risk of traumatic dental injury due to overjet using several published papers and performing a meta-analysis on the results. The 11 articles involved in this investigation were identified by a literature search of Medline (1966-1996) and Exerpta Medica (1985-1996) databases using predetermined keywords, and inclusion and exclusion criteria. In order to...
AIM The present study was conducted to assess the correlation of traumatic dental injuries and overjet among school going girls of age 11 to 17 years in Pune, India. MATERIALS AND METHODS A cross-sectional survey was carried out with 2045 school girls aged 11 to 17 years, attending public elementary schools in Pune, India. The traumatic dental injuries were assessed according to Ellis and Dav...
Aim. To determine whether a relationship exists between the linear measurements of overjet and overbite and the interincisal space delimited by the morphology of the upper and lower incisors. Method and Materials. 30 subjects (age range from 14.1 to 34.8 years, with a median age of 23.5 years and sex ratio F/M: 5/10) with overjet and overbite equal to 2 mm were selected from a group of 381 indi...
Abstract: Introduction: The increased overjet in Class II Division 1 malocclusion subjects may be due to hyperdivergent growth pattern or Bolton’s tooth size discrepancy. The aim of this investigation was to find the rational factor for overjet in Class II Division 1 malocclusion as growth pattern or Bolton's discrepancy in these subjects. Methods: 120 untreated Class II Division 1 cases who re...
Background: The skeletal correlations in a sagittal plane do not correlate to the dental relationship each time. For orthodontic treatment planning, differential identification In past, terms overjet and overbite were used examine jaw connections. goal of study was see how closely characteristic (overjet) correlated with angles (ANB, WITTS). Objectives: This research aims if occlusal characteri...
INTRODUCTION In preorthodontic children with Class II malocclusion and horizontal maxillary overjet, cervical column morphology was examined and related to craniofacial morphology and head posture for the first time. METHODS Two hundred thirteen children (aged 7-15 years) with a horizontal maxillary overjet of more than 6 mm were divided into 2 groups of skeletal and dentoalveolar overjets. T...
