Abstract

Maxillary midline diastema (MMD) is a common aesthetic problem of people seeking orthodontic problem, which means
spacing greater than 0.5 mm between the proximal surfaces of maxillary central incisors. The causes for MMD may be: high
frenum attachment; microdontia; macrognathia; supernumerary teeth; peg laterals; missing lateral incisors; midline cysts and
unhealthy oral habits.
Objectives: The purposes of this study were to determine the prevalence of MMD among Shorish dental clinic`s patients
seeking orthodontic treatment and to find the factors associated with this anomaly.
Materials and Methods: During 6 months, 507 patients with age (13 – 40) years old attending Shorish Dental Clinic, seeking
orthodontic treatment were screened to find the prevalence and etiology of MMD.
Result: The MMD was present in 110 patients (21.7%). The frequency of MMD was the same in males and females. It is
highest in the young age group and lowest in the older age group (29% vs. 4%).
Conclusion: The most frequent factor among the observed etiological factors was oral unhealthy habit which was found in
40% of MMD patients and 8.7% of all cases.
