Abstract
Background: Correction of deep bite is crucial for maintenance of dental hard and soft tissue structures and for prevention of temporomandibular joint disorders.Exploration of underlying skeletal and dentalfactors is essential for efficient and individualized treatment planning. To date etiological factors of dental and skeletal deep bite have not been explored in Pakistani orthodontic patients. The objectives of this study were to explore frequencies of dental and skeletal etiologicalfactors in deep bite patients and to determine correlations amongst dental and skeletal etiological factors of deep bite. Methods: The study included a total of 113 subjects (males=35; females=78) with no craniofacial syndromes or prior orthodontic treatment. Pre-treatment orthodontic records were used to evaluate various dental and skeletal parameters. Descriptive statistics of each parameterwere calculated. The various study parameters were correlated using Pearson’s Correlation.Results: Deep curve of Spee was most frequently seen factor of dental deep bite(72.6%), followed by increasedcoronal length of upper incisors (28.3%), retroclined upperincisors (17.7%), retroclined lower incisors (8%) and increased coronal length of lower incisors (5.3%). Decreased gonial angle was most commonly foundfactorof skeletal deep bite (43.4%), followed by decreased mandibular plane angle (27.4%) and maxillary plane's clockwise rotation (26.5%).Frankfort mandibular plane angle and gonial angle showed a strong positive correlation (r=0.66, p=0.000).Conclusions: Reduced gonial angle is most frequently seen skeletal factor, signifying the importance of angulation and growth of ramus in development of deep bite.Deep curve of Spee ismost frequently seen dental etiological component in deep bite subjects, hence signifying the importance of intruding the lower anterior teet
