The present case report describes the interdisciplinary management of a patient with increased overbite and overjet, Angle’s Class Ⅰ malocclusion, bilateral agenesis mandibular central incisors microdontia upper lateral incisors. 18-year-old female had convex profile, maxillary dentoalveolar protrusion mild spacing in anterior region. Therefore, treatment consisted fixed appliance therapy, foll...
the success of endodontic therapy requires knowledge of the internal and external dental anatomy and its variations in presentation. this case report involves endodontic treatment of a traumatized maxillary central incisor with two separate roots.
Luxational injuries to the permanent anterior teeth in children are a cause of concern. Palatal luxation of maxillary left central incisor with bleeding of gingival sulcus and fracture of maxillary right central incisor involving enamel and dentine in a 9-year- old girl is presented. The dental occlusion was deranged due to the luxation. Management consisted of repositioning of the luxated toot...
Dilaceration is a comparatively uncommon dental deformity generally characterized by an angulation between crown and root, and consequently causing non-eruption of the tooth. Dilaceration generally occurs following trauma to the apices of deciduous dentition, which lies close to the permanent tooth buds. As a result, surgical extraction used to be the first choice when making the treatment plan...
This case report describes the treatment of a patient with a horizontally impacted maxillary central incisor, a canine in the same quadrant, and an inclusion tendency. Due to severe crowing in the maxilla and the Class II molar relationship on the impaction side, a 2-stage treatment plan was developed. In the first stage, the right first premolar and deciduous canine were extracted; this allowe...
Background: Dilaceration is a rare dental condition that can occur during tooth development, resulting in distortion of the normal axial relationship between crown and root. Although it affect any tooth, most commonly occurs permanent incisors, often as result trauma to primary predecessor. The impact even slight displacement incisor be significant, disrupting development follicles new teeth. D...
INTRODUCTION Dental transposition and impaction are disorders related to ectopic eruption or failure in tooth eruption, which can affect child physical, mental and social development and may be difficult to be clinically solved. METHODS We describe a case of transposition between the upper left canine and lateral incisor associated with impaction of the central incisor on the same side, in a ...
INTRODUCTION The aim of this paper was to study the effect of transmandibular distraction on the periodontal and dental structures, and the initial movements of the mandibular halves, when using an axial plane non-rigid bone-borne distractor (TMD). MATERIAL AND METHODS Fourteen patients undergoing bimaxillary transverse osteodistraction had their six lower anterior teeth assessed for mobility...
Radiologic indicators for prediction of difficult laryngoscopy in patients with cervical spondylosis
BACKGROUND We identified the most useful variables for prediction of difficult laryngoscopy in patients with cervical spondylosis according to physical indicators and preoperative skeletal X-ray and soft tissue MRI measurements. We hypothesized that there was a closer association between difficult laryngoscopy and radiologic indicators. METHODS We randomly enroled 315 patients undergoing elec...
UNLABELLED New radiographic maxillofacial techniques, cone beam computerized tomography (CBCT) are a necessity in the assessment of jaw bone offer to effectively evaluate the treatment. AIM To quantitatively and qualitatively evaluate anterior mandibular area on CBCT comparing to orthopantomography (OPG). MATERIAL AND METHODS Fifty-one dental patients, aged between 20 and 77 years, were qua...
