Abstract

This pilot study for a split-mouth, randomised, clinical trial compared the incidence of postoperative complications, root migration, and adjacent second molar periodontal attachment after coronectomy of the lower third molars with or without guided bony regeneration. Six patients (three men and three women, mean (range) age 27 (21-44) years), each with bilateral lower third molars in close proximity to the inferior alveolar nerve, were recruited. One third molar of each patient was randomised to be treated by coronectomy with guided bony regeneration, and the other side coronectomy alone. All subjects were reviewed for 12 months. No neurosensory deficit was noted in either group. We found no significant differences between the two groups in postoperative morbidity. Mean (SD) root migration after coronectomy with guided bony regeneration at postoperative 2 weeks, 3 months, 6 months, and 12 months were 0.14 (0.34), 0.56 (0.68), 0.63 (0.83), and 0.63 (0.83) mm, respectively. These were significantly less than the results in the control group from postoperative 3 months onwards (3 months p=0.01, 6 months p=0.004, and 12 months p=0.003). There was a trend towards reduced periodontal depth at the adjacent second molar in the study g...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
