This report describes the nonsurgical treatment of a patient with skeletal Class II protrusion and severe crowding. A 20-year-old woman presented with the chief complaint of lip protrusion and crowding. To correct the Class II relationship, severe crowding, and lip protrusion, distal movement of the maxillary first molars using indirect miniscrew anchorage and nickel-titanium coil springs, alon...

The maxillary first premolar may present large number of anatomic variations. The clinician should be aware of the configuration of the pulp system. Maxillary first premolars usually have two canals. The incidence of three canals in these teeth is quite rare. This case report presents the diagnosis and clinical management of a maxillary first premolar with two distinct canals in the apical thir...

In our orthodontic practice we have seen a recent spurt of increasing numbers of young adults who desire cost effective, non surgical correction of Class II malocclusion and accept dental camouflage as a treatment option to mask the skeletal discrepancy. When planning the treatment in such cases the orthodontist often faces the dilemma whether to extract 2 maxillary premolars or 2 maxillary and...

OBJECTIVE To determine the internal root morphology of the maxillary first premolar in Kenyans of African descent. DESIGN In vitro descriptive cross-sectional study. SETTING School of Dental Sciences, University of Nairobi. SUBJECTS One hundred and fifty five extracted maxillary first premolars obtained from patients aged between 13-30 years attending dental clinics within Nairobi. RESU...

Bi-maxillary protrusion is a condition with protrusive and proclined upper lower incisors the patient not able to close lips without strain. The presented case reported chief complaint of forwardly placed teeth, skeletal class II malocclusion, Angle’s I malocclusion incisors. treatment was performed extraction all first premolars retraction under absolute anchorage. about 3 mm 3.5 achieved resp...

PURPOSE The objective of this study was to assess the pattern of permanent teeth present in a self-selected sample of 17 female and 35 male patients with ectodermal dysplasia presenting for treatment with dental implants. METHODS Mean age of sample: 18.7 years, age range: 5.9 to 60.9 years. Panoramic radiographs were examined independently by two investigators to determine the permanent teeth...

OBJECTIVE To evaluate the efficiency of the Frog appliance (FA) alone or in combination with headgear for distalizing the maxillary molars. METHODS Fifty patients (25 males and 25 females) aged 12.6 - 16.7 years who received treatment for Class II malocclusion at the Orthodontic Clinic of Al-Baath University were selected for this study and randomly divided into 2 equal groups. Maxillary mola...

The purpose of this study was to relate the proportions of bone-supported root length of a 2D view into the amount of a 3D bone-attached root surface area (BA-RSA) by using a dental laser scanner examination. White-light 3D scanning technology was used to probe 36 maxillary and 35 mandibular single-rooted premolars. The bone-supported height (BSH) and BA-RSA at designated levels (95-25%) were c...

INTRODUCTION The purpose of this study was to evaluate the skeletal and dental changes in patients who underwent distalization of their maxillary molars with pendulum appliances. METHODS The sample consisted of 31 patients (initial mean age, 14.58 years) with Angle Class II molar relationships and all permanent teeth up to the second molars. The maxillary molars were distalized with pendulum ...
