This case report presents the interceptive orthodontic treatment of a 9-year, 5-month-old boy with class I malocclusion, a 9.0-mm maxillary midline diastema, and deviation from the midline. The treatment goals were to decrease the magnitude of the diastema and to simulate the characteristics of the "ugly duckling" stage. Braces were placed on the first molars and the maxillary central incisors....
PURPOSE This study aimed to evaluate the use of orthodontic mini-implants for the intrusion of supraerupted maxillary molars. MATERIALS AND METHODS Nine patients were treated using buttons bonded on dental surfaces and mini-implants inserted on the buccal and palatal sides. The intrusion was evaluated by comparing radiographs obtained at the start of treatment and at the end of intrusion. The...
BACKGROUND The objective of this study was to investigate whether multistranded fixed retainers prevented overeruption of unopposed mandibular second molars in maxillary first molar extraction cases. METHODS The panoramic radiographs of 65 Class II Division 1 Caucasian Whites (28 females, 37 males) consecutively treated with bilateral maxillary first molar extraction and the Begg technique, a...
Maxillary molar distalization is an increasingly popular option for the resolution of Class II malocclusions. This communication describes the effects of one particular molar distalizing appliance, the distal jet, in a sample of 20 consecutively treated and growing subjects (11 females, nine males; mean starting age of 13) and compares these effects with those of similar devices. Pre- and postd...
OBJECTIVES The aim of the present study was to assess the relationship between the maxillary sinus floor and the maxillary posterior teeth root tips using dental cone-beam CT. METHODS A total of 87 right and 89 left maxillary sinus regions from 92 patients were examined using dental cone-beam CT. Images were analyzed by a specialist in oral and maxillofacial radiology. Perpendicular lines wer...
OBJECTIVE To determine the prevalence and pattern of early childhood caries among three to five year olds. DESIGN This was a descriptive, cross-sectional study. SUBJECTS A total of 336 children aged 3-5 years. SETTING Pre-schools in Kiambaa division, Kiambu District, Kenya. RESULTS Slightly over a half, 201 (59.5%) had dental caries. The mean decayed, missing and filled teeth (dmft) was...
Central accessory cusp in primary molars is an extremely rare condition which is due to abnormal proliferation and folding of inner enamel epithelium during morphodifferentiation stage of tooth development. The extension of the pulp in the cuspal area is often the reason for early involvement of pulp by the caries process. Therefore, early diagnosis and treatment planning is necessary to mainta...
Evaluating third molars from 950 Hispanic individuals aged 12-22 years using Demirjian's schematic for crown and root formation found that Hispanic third molar development was 8-18 months faster than American Caucasians as reported by Mincer, Harris and Berryman in 1993. This represents a statistically significant increase. Earlier development was more apparent in the later stages F through H. ...
The effects of extraoral combined high-pull traction and cervical traction of known duration (mean, 122 days) and magnitude (2.5 to 3 pounds total per side) were studied by means of serial lateral cephalometric head films of thirty patients. The lateral cephalometric head films used were taken at three different times: before the extraoral force was applied, after the prescribed period of conti...
The purpose of this study was to investigate the determinability of the distance between the pulp horns (PHD) radiographically under routine clinical conditions. This study was carried out on 36 maxillary and 28 mandibular first and second molars which were extracted because of periodontal diseases. Prior to extraction two radiographs were taken from each tooth, one using the bisecting-angle te...
