A fixed orthodontic appliance utilizing light continuous forces to correct an anterior crossbite is described. This appliance can serve as an alternative to other methods of anterior crossbite correction in the permanent dentition. One of the major responsibilities of the dental practitioner is to intercept adverse patterns of dental eruption in the child. 1 Among the developmental problems fre...
PURPOSE The purpose of this study was to examine the relationship between the specific types of medication, length of use, frequency of use, and dosing time of day on the dental caries of children diagnosed with asthma. METHODS Using a patient list from a previous study, surveys were mailed to the parents of 179 asthmatic children. The survey itself consisted of a table that asked 4 questions...
Introduction Mesial drifting of molar teeth in maxillary arch is corrected by movement of the molars distally. In addition to traditional distal movement techniques, such as extraoral force application and removable appliances, various intra-arch devices have been introduced since 1980s. These intra-arch appliances have nearly eliminated the need for patient cooperation. Case report The purpo...
BACKGROUND The aim of this randomized clinical trial was to assess the effect of early orthodontic treatment for unilateral posterior cross bite in the late deciduous and early mixed dentition using orthopedic parameters. METHODS Early orthodontic treatment was performed by initial maxillary expansion and subsequent activator therapy (Münster treatment concept). The patient sample was initial...
This paper reports a case treated by a serial extraction program at the mixed dentition stage followed by a corrective orthodontic treatment, with a long-term follow-up period. Twenty years after the interceptive treatment, a harmonious face was observed along with treatment stability in the anterior posterior direction, deep overbite (which has been mentioned as a disadvantage of the serial ex...
UNLABELLED AUTHORS: Franchi L, Baccetti T. OBJECTIVES The aim of the present study is to evaluate the dentoskeletal features of subjects with either Class II or Class III malocclusions in the mixed dentition using both conventional cephalometric analysis and TPS morphometric analysis applied to posteroanterior (PA) cephalograms. DESIGN TPS analyses of PA cephalograms on 49 Cl-II, and 20 Cl-...
Pseudo Class III malocclusion is characterized by an anterior crossbite with functional forward mandibular displacement. Various appliances have been devised for early treatment of a pseudo Class III. The aim of this article is to highlight the method of construction and use a simple removable appliance termed as "Modified Hawleys appliance with inverted labial bow" to treat psuedo class III ma...
PURPOSE The purpose of this study was to investigate the survival rate and median survival time of different stages of proximal caries in 196 children aged 6 to 8 years at baseline examination. METHODS Proximal caries and its progression were diagnosed from bitewing radiographs taken at 1-year intervals over a period of 4 years. The mesial surface of the first permanent molars, the mesial and...
AIM Anterior open bite (AOB) is an occlusal anomaly commonly associated with oral habits (OH). The aim of this study was to determine the prevalence of OH as a risk factor for the AOB. MATERIALS AND METHODS A group of children aged between 3 and 12 years were observed. The statistical methodology included independent chi-square test, Fisher's exact test and binary logistic regression. RESUL...
BACKGROUND/AIM In malocclusion of skeletal class III, mandible is located in front of maxilla in sagital plain, which is manifested by a lower value of the sagital inter-jaw angle than in skeletal class I, where the jaw sagital relation is normal. Apart from the deformities on mandible and/or maxilla, in skeletal class III deformities are also frequent on the cranial base. The aim of this resea...
