The aim of this study is to test the response of bone during cutting actions in dental procedures by sampling alkaline phosphatase (ALP) as a biological reference marker. ALP is found abundantly in bone tissue. In the first series of experiments a temporal-minimum quantity of ALP enzyme response was recorded, the observed period was 40 minutes. The ALP samples treated with piezoelectric surgery showed a rapid increase, with peak at 30 min, and then declined rapidly within the next 10 minutes. A second experiment was performed to evaluate 4 cutting instruments: drill bits high speed turbine (T1); drill bits contra-angle (T2) Piezoelectric insertions (T3), and manual instruments (controls). This second experiment was to evaluate the ALP activity at 30 min. The T1 samples produced the highest results (3,66499 +- 0,51394); control groups had a lower response (0,72793 +- 0,22353), while the T2 group produced statistically significant higher results (2,77793 +- 0,40553) than T3 (1,16608 +- 0,32676). The different values obtained for ALP in these two experiments for a short period of time (30 min) cannot be interpreted as a response of bone tissue regeneration subjected to surgical trauma. The MINIMUM trauma caused by the surgical piezoelectric instruments, in respect to conventional surgical instruments is clearly evident from the phosphatase inflammatory activity.

Abstract

The aim of this study is to test the response of bone during cutting actions in dental procedures by sampling alkaline phosphatase (ALP) as a biological reference marker. ALP is found abundantly in bone tissue. In the first series of experiments a temporal-minimum quantity of ALP enzyme response was recorded, the observed period was 40 minutes. The ALP samples treated with piezoelectric surgery showed a rapid increase, with peak at 30 min, and then declined rapidly within the next 10 minutes. A second experiment was performed to evaluate 4 cutting instruments: drill bits high speed turbine (T1); drill bits contra-angle (T2) Piezoelectric insertions (T3), and manual instruments (controls). This second experiment was to evaluate the ALP activity at 30 min. The T1 samples produced the highest results (3,66499 +- 0,51394); control groups had a lower response (0,72793 +- 0,22353), while the T2 group produced statistically significant higher results (2,77793 +- 0,40553) than T3 (1,16608 +- 0,32676). The different values obtained for ALP in these two experiments for a short period of time (30 min) cannot be interpreted as a response of bone tissue regeneration subjected to surgical trauma. The MINIMUM trauma caused by the surgical piezoelectric instruments, in respect to conventional surgical instruments is clearly evident from the phosphatase inflammatory activity.
