Objective: The objective of this study was to determine frequency and factors responsible for the fracture of maxillary tuberosity during extraction of the maxillary 3rd molar.
Material and Methods: A detailed history, clinical and radiographic examination was carried out for 200 patients requiring upper 3rd molar extraction. Patients having age range from 20 to 60, and any medical condition affecting bone physiology were included. Patients having any pathology in maxillary sinus like tumors or maxillofacial trauma or requiring prophylactic extraction before radiotherapy were excluded from the study. Factors responsible for maxillary tuberosity fracturen like age, gender, occupation, general medical condition, root morphology, thickness/density of surrounding bone, and pre-extraction condition of upper 3rd molar were recorded. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 20.0. Descriptive statistics were calculated. Chi- square test was applied to see the effect of responsible factors on maxillary tuberosity fracture. P value <0.05 was considered significant.
Results: Males outnumbered females with a mean age of 30.39±7.54 years. The frequency of maxillary tuberosity fracture during upper third molar extraction was 5%. The effect of root morphology, age and surrounding thickness/ density of bone on the fracture of maxillary tuberosity was statistically significant (p-value <0.05). The effect of pre-extraction condition of the upper third molar crown and patients’ occupation on the fracture of maxillary tuberosity was not statistically significant (p-value >0.05).
Conclusions: Overall frequency of maxillary tuberosity fracture is higher than reported in earlier studies. The responsible factors for maxillary tuberosity fracture were the old age, root morphology, and thickness of surrounding bone..
