Solitary median maxillary central incisor syndrome (SMMCI) is a complex disorder consisting of multiple, mainly midline defects of development resulting from unknown factor(s) operating in utero about the 35th-38th day(s) from conception. It is estimated to occur in 1:50,000 live births. Aetiology is uncertain. Missense mutation in the SHH gene (I111F) at 7q36 may be associated with SMMCI. The ...

Background: A common problem that requires orthodontic intervention is maxillary lateral incisor agenesis. A common treatment for this problem is to open space for a maxillary lateral incisor implant. However, that treatment is expensive. Often, parents with this problem wonder if their children will also have this anomaly. Objective: To determine the relative risk of a parent with maxillary la...

thorough understanding of the anatomic and internal morphology of a root canal system is absolutely essential for the success of endodontic treatment. since permanent maxillary first molars have shown variation in internal anatomy, morphology, this tooth has been reviewed extensively. presence of two canals in a two-rooted maxillary first molar has rarely been reported in studies describing too...

BACKGROUND The paradigm shift from occlusion to esthetics places more emphasis on the subtle relationships among the teeth and the interplay with the soft tissues. The authors of this study quantified the ideal and maximum acceptable deviations for smile characteristics. METHODS The authors created a survey by using a digital image editing software package, which enabled raters to manipulate ...

T alon cusp refers to a cusp-like structure project ing from the cingulum area of a maxillary or mandibular anterior tooth. Shafer et al. and Mellor and Ripa reported that talon cusp is uncommon and occurs in maxillary and mandibular permanent incisors. Most cases of the anomaly have been reported in the permanent dentition. Ninety percent of the talon cusps occur in anterior permanent teeth, a...

Radicular fractures in permanent teeth are uncommon injuries and account for only 0.5-7% of dental traumas. These fractures commonly result from a horizontal impact and are transverse to oblique in direction. Their incidence is more in the middle third of the root than at the apical and cervical thirds. This paper describes a case of complicated crown fracture of maxillary incisors along with h...

Dental trauma sometimes causes fractures in the maxillary anterior teeth leading to esthetic, functional and phonetic quandaries. In this report, we describe the treatment of middle third root fracture of maxillary centrals and cervical third crown fracture of lateral incisor simultaneously fractured due to dental trauma. Treatment involved reattachment and splinting of fractured fragments with...

Mechanical trauma or developmental disorders can cause an eruptive problem mostly called dilaceration. The prognosis of a dilacerated tooth depends on early diagnosis and appropriate treatment planning. The case presented in this paper is an example of severe dilacerations of a maxillary central incisor which has been treated with early orthodontic intervention.

We present a girl with del(18p) syndrome and a single maxillary central incisor; she is only the second patient in whom this association has been reported.
