STATEMENT OF PROBLEM Agenesis of the maxillary lateral incisor has been linked to differences in the size of the remaining teeth. Thus, the mesiodistal space required for definitive esthetic restoration in patients with missing maxillary lateral incisors may be reduced. PURPOSE The purpose of this study was to determine whether a tooth size discrepancy exists in orthodontic patients with agen...

Aberrations in tooth morphology resulting from late disturbances during the differentiation process most commonly result in size variations. Peg-shaped or mesio-distally deficient maxillary lateral incisors demonstrate variation in the expression of the trait, although the genes causing this are not known. Individuals with malformed lateral incisors often display a diastema in the midline regio...

AIM To describe the successful non-surgical endodontic management of a permanent maxillary lateral incisor tooth with four root canals. SUMMARY Aberrant morphology of root canals can occur in any tooth, including maxillary lateral incisors. In the presented case, clinical examination and radiographs clearly depicted the presence of four root canals in a right maxillary lateral incisor. The di...

objectives: proper diagnosis and prevention of malocclusion are superior to treatment. discrepancy between arch length and tooth size in mixed dentition period is a condition requiring timely diagnosis. estimating the mesiodistal width of unerupted teeth according to the size of erupted ones can lead to earlier diagnosis of malocclusion. on the other hand, the best timing for serial extractions...

OBJECTIVE To investigate the root and canal morphology of permanent mandibular anterior teeth in a Chongqing population using cone-beam computed tomography (CBCT). METHODS CBCT images of 1,725 patients in a Chongqing population were selected, and a total of 9,646 mandibular anterior teeth were analyzed. The number of root canals and the canal configurations were investigated. RESULTS In tot...

The purpose of this study is to compare the anterior tooth size width in patients with congenitally missing maxillary lateral incisors using the Bolton Index and divine proportion. The study sample consisted of thirty pairs of orthodontic models with unilateral (twelve patients; 7 females, 5 males) and bilateral (eighteen patients; 13 females, 5 males) absence of maxillary lateral incisors. The...

Objective: The aim of this study was to document the prevalence of maxillary permanent canine impaction in relation to anomalous adjacent lateral incisors in a Turkish population. Materials and Methods: Pretreatment orthodontic records of 68 subjects (27 male, 41 female) with palatal or buccal impaction of one or both permanent maxillary canines were included in this study. Localization of the ...

Familiarity with the intricacies and variations of root canal morphology is essential for successful endodontic treatment. Maxillary central and lateral incisors are known to be single-rooted with one canal, however, this case report describes endodontic treatment of maxillary central and lateral incisors with two buccopalatal root canals.

PURPOSE The purpose of this study was to measure the buccal bone thickness and angulation of the maxillary incisors and to analyze the correlation between these parameters and the root position in the alveolar bone using cone-beam computed tomography (CBCT). MATERIALS AND METHODS CBCT images of 398 maxillary central and lateral incisors from 199 patients were retrospectively reviewed. The roo...
