Determine the clinical and radiographic criteria which may be used in diagnosing root fractures.
- N= 468 teeth with vertical root fractures due to corrosion of pins and posts.
- Patients were referred to oral surgery practice between 1953-1968. Diagnosis of root fracture confirmed by direct inspection of the extracted tooth or by exploratory flap.
1.Fractures occurred in 297 females (68%) and 136 males (31%)
2.Maxillary 2nd Premolar was most often site of fracture
- Periodontal pocket usually present
- Paper points inserted into the pockets came out black due to corrosion
- Dark discoloration of gingiva sometimes present
- Abscess were found closer to gingival margin rather than apical area
- Fracture lines observed in 35% of radiographs. Could only be seen within an angle of 8 degrees only.
- Bone destruction indicates location of fracture
Various signs, both radiographically and clinically, may be present to aid in diagnosis of root fractures in teeth with pins or posts.
