A DESCRIPTIVE ASSESSMENT OF ANTERIOR OPEN BITE OCCURRENCES ON A TARGET SAMPLE: A CROSS-SECTIONAL RESEARCH

Anterior open bite exists as a gap which is acute and vertical between upper incisors and lower incisors along with centric occlusion teeth. Multiple factors are involved in the anterior open bite aetiology. These factors have multiple environmental and genetic features which are reflected in the shape of the palate, cleft lips and muscular dystrophy disorders also known as pathologic disorders with associated developmental factors. The objective of this particular research was to determine the anterior open bite occurrences in the selected population. A total of 300 patients reported in the Services Hospital, Lahore (October 2017 to June 2018). All these patients were examined for detailed clinical assessment and history. We also documented the alginate impression models and materials among patients who were dispensed in dental stones. We also measured dental casts in millimetres with the help of Vernier Calipers with a minimum count of (0.01) millimetre. Statistical analysis was made through SPSS software. Every variable was also tabulated for percentage and occurrence. The research participants were in the age bracket of (15 – 30) years and the mean age of the research participants was (16.2 ± 5.2) years. Female population dominated the male population as females were 56.6% and males were 44.4%. There were 14 patients of Anterior open bite (4.6%). Nine patients presented less severe open bite which was under one millimetre (3%); whereas, severe open bite patients were 5 having severity in the range of >1 to 2 millimetres (1.6%).
