Previous research into the origins of lower incisor crowding have not yet established the part played by skeletal morphology in its development. Longitudinal cephalometric records of twelve cases with spaced lower teeth were compared with those of twelve moderately crowded cases and twelve severely crowded cases. Significant differences were found between the three groups. These suggested that ...

INTRODUCTION Literature reports on a method for dental age calculation which is based only on radiological measurements on periapical dental radiographs: the relationship between chronological age and the two-dimensional dental pulpal size was analysed by means of multiple regression analyses. The purpose of the present study was to evaluate whether this approach could be feasible and could lea...

Clinicians agree that tooth agenesis regardless of gender or race becomes more prominent in recent societies. The congenital absence of one or more maxillary lateral incisors is a challenge to effective treatment planning for the restorative dentist. The one-sided orthodontic approach of moving canines mesially to eliminate restorative procedures also leads to compromise. Adult patients present...

The majority of dental trauma involves anterior teeth, especially the maxillary central incisors. A mandibular incisor fracture with or without pulp tissue involvement is considerably less common. Different approaches for treating these fractured teeth have been reported in the literature. The type of treatment rendered depends mainly on the extent of fracture, pulp involvement, radicular fract...

The cephalometric appraisal of mandibular incisor teeth in relation to the basal bone had its origin clinical outcomes that Tweed observed his treated cases. Although was an admirer Angle’s philosophy, failure achieve functional and aesthetic harmony some orthodontically cases prompted introspect methodology revisit records patients. Consequently, based on annotations aid, a Diagnostic Facial T...

T he role of mandibular third molars in the relapse of lower anterior crowding following the cessation of retention in orthodontically treated cases has provoked much speculation in the dental literature over the past 115 years. In 1859 Robinson’ wrote : “. . the dens sapicntiae . . is . . frequently the immediate cause of irregularity of the teeth by the pressure exerted towards the anterior p...

BACKGROUND The prophylactic removal of asymptomatic impacted wisdom teeth is defined as the (surgical) removal of wisdom teeth in the absence of local disease. Impacted wisdom teeth may be associated with pathological changes, such as inflammation of the gums around the tooth, root resorption, gum and alveolar bone disease, damage to the adjacent teeth and the development of cysts and tumours. ...

mandibular incisor extraction in carefully selected cases as an alternative option to four bicuspid extraction or non extraction treatment has been advocated. the purpose of this study was to determine the degree of improvement in occlusion in patients with bolton discrepancy treated by one lower incisor extraction using peer assessment rating index (par indexes).pre and post treatment dental c...

Bimaxillary protrusion in a 28-year-old woman was complicated by multiple missing, restoratively compromised, or hopeless teeth. The maxillary right central incisor had a history of avulsion and replantation that subsequently evolved into generalized external root resorption with Class III mobility and severe loss of the supporting periodontium. This complex malocclusion had a discrepancy index...

THE CASE A 30 years old man presented with the main complaint of loose lower denture with which he was unable to chew and speak properly. The loss of multiple teeth (fig.1) was from an alleged roadside accident and it was also associated with multiple fractures of the lower jaw. Upon clinical examination, it was found that the mandibular teeth distal to the left lateral incisor, except for the ...
