A longitudinal study on electrical pulp testing following Le Fort type osteotomy and Le Fort type fracture.
A longitudinal study of electrical pulp testing was carried out in 27 cases, or 53 maxillary halves following Le Fort type fractures and Le Fort type osteotomies. On the average, most teeth required positive responses around 7 months or around 11 months afterwards. The central and lateral incisor teeth demonstrated poor results; only 8 percent and 36 percent responded positively at 8 months, and at 14 months, 23 per cent  and 50 per cent, respectively. The overall percentage of responsive teeth was 29 percent at 6 months and 85 percent at 14 months. These results are discussed and compared with those of segmental maxillary osteotomy, together with the value of pulp testing in the diagnosis in fracture and osteotomy.
