“…These children had indistinct philturm, arch-shaped upper lip, absence of labial frenum of upper lip, complete/ incomplete mid-palatal ridge, SMMCI, nasal obstruction, narrow nasal cavities, septum deviation, retrognathia and posteriorly inclined maxilla and mandible, larger cranial base angle, reduced anterior cranial base length, and maxillary length and a deviant morphology of sella turcica in five out of ten patients. [2] Tabatabaie et al also reported similar findings in a group of thirteen patients with SMMCI. [9] Apart from the presence of few of the above-mentioned anomalies the child in the present report also had abnormal sella morphology.…”

“…[1] HPE spectrum can be classified into five different types; cylopia, ethmocephaly, cebocephaly, median cleft palate, and short upper lip (with mid-palatal ridge and SMMCI). [2] Although SMMCI could be a predictor of HPE, in the majority of cases HPE occurs in the absence of SMMCI. The incidence of SMMCI is 1:50000 and that of HPE is 1:16000 live births.…”

“…[1] Most severe cases of HPE do not survive and may appear as spontaneous abortions, and less severe cases may be characterized by an SMMCI. [2] Hence, SMMCI may first be detected by a pedodontist or an orthodontist. SMMCI syndrome could be a developmental field effect involving midline structures of the body due to unknown events occurring between 35 th and 38 th days of intrauterine life.…”

Solitary median maxillary central incisor (SMMCI) syndrome is considered as a microform of holoprosencephaly (HPE) spectrum. It is a unique developmental abnormality affecting midline structures of the body. Systemic abnormalities involve major systems of the body such as cardiovascular, gastrointestinal, renal, endocrine, genital, and skeletal systems. Abnormal features involving eyes, ears, nose, mouth, and skin are also present. SMMCI patients belong to the HPE spectrum, and hence are at risk of having children with a more severe form of HPE. Very often SMMCI patients may first be seen by a pedodontist or an orthodontist and it is important that the dentist performs a complete examination to rule out systemic abnormalities and involve a multidisciplinary team to manage the patient. This article reports about a 5-yearold male child who reported with dental abscess in whom SMMCI was an incidental finding. Further investigations revealed the association of SMMCI with anomalies such as chronic respiratory obstruction, short stature, abnormal clinical and radiographic craniofacial morphology, duplicated left thumb phalynx, and absent left testis.

“…[1][2][3][4][5][6][7][8] On the other hand, most of these pathologic conditions, developmental abnormalities, or normal variants are associated with a significant problem in other systems. 4,9,10 Interestingly, some of these findings are detectable very early in life 11 and often precede other signs or symptoms in syndromes. Therefore, in some cases, they could potentially be valuable for an early diagnosis.…”

Objective: To test the null hypothesis that there is no increased prevalence of skeletal anomalies and/or normal variants as evidenced by the cephalometric radiographs of patients with palatally displaced canines (PDC). Materials and Methods:The treatment records of 38 white subjects between 14 and 20 years old with PDC were collected and evaluated retrospectively. Inclusion criteria for the study required that the case records include good-quality panoramic radiographs and lateral cephalometric radiographs with the first four cervical vertebrae clearly visible. The anomalies recorded for each case included sella bridge, atlanto-occipital ligament calcification or ponticulus posticus, and posterior arch atlas deficiency. A control group consisted of 70 consecutively treated subjects who had no other dental anomalies and whose maxillary canines had erupted normally. Fisher's exact test and Pearson's chi-square test were used to determine possible statistically significant differences in the incidence of skeletal anomalies and/or normal variants between the group of patients with PDC and the control group. Results: The prevalence of skull anomalies and normal variants seen in cephalometric radiographs was increased in patients with PDC. Because of the presence of ponticulus posticus (Pearson's chi-square, P Ͻ .050; Fisher's exact test, P Ͻ .052), sella bridge (Pearson's chisquare, P Ͻ .042; Fisher's exact test, P Ͻ .042), and posterior arch deficiency (Pearson's chisquare, P Ͻ .047; Fisher's exact test, P Ͻ .039), statistically significant differences were observed between subjects with PDC and the control group. Conclusions: The null hypothesis was rejected. There is an increased prevalence of skull skeletal anomalies and/or normal variants in patients with PDC. (Angle Orthod. 2009;79:727-732.)
