To evaluate the frequency and severity of the malocclusions and treatment need in a group of adult patients in Târgu-Mureș, dividing them up according to age and gender.Sixty-four, randomly selected patients were divided up according to age and gender. Ten occlusal traits related to dentofacial anomalies according to missing teeth, spacing, crowding and occlusion were used to evaluate the malocclusions on each of their study cast. The Dental Aesthetic Index (DAI) regression equation was used to obtain the DAI score that defines severity.The average DAI score was 38 with a range of 18-79, showing that the majority of patients needed mandatory orthodontic treatment. No statistically significant difference was found between gender, age groups and need for treatment.More than two-fifths of the examined patients have a mandatory need for orthodontic treatment if the DAI scores are the main screening tool.
