Hematologic analysis after gingivectomy

Peripheral blood specimens were taken from ten m en before simple quadrant gingivectomies and 2 and 4 days after the operations. N o significant changes oc­ curred in leukocyte counts, differential neutrophil counts, erythrocyte sedim enta­ tion rates, packed cell volum e and hem o­ globin concentration.

Peripheral blood changes after a simple q u a d ra n t gingivectomy were observed to learn w hether gingivectomy provokes a systemic reaction. Leukocyte, differential neutrophil and lymphocyte counts, ery­ throcyte sedim entation rate, packed cell volume an d hemoglobin concentration were determ ined. T h e peripheral blood was draw n imm ediately before the gingi­ vectomy (controls) and 2 an d 4 days postoperatively. B A CK G R O U N D

Blood changes after tooth extraction have been studied by others. Shannon, Davis and Gibson1 reported th a t hem atologic changes occur 4 hours after tooth extrac­ tion, but not all these changes persist for 2 days and 4 days postoperatively. Four hours after tooth extraction, significant changes were as follows: (1) increase in white blood cells, (2 ), increase in neutro­

phils, (3) decrease in lymphocytes, (4) decrease in packed cell volume and (5) increase in corrected sedim entation rate. A fter two days, blood chemistry in­ dexes returned to norm al except for the corrected sedim entation rate, w hich re­ m ained elevated through the fourth day. Cheraskin,2 too, found an increase in sedim entation rate four days after tooth extraction. In seven patients, w ho had had an uncom plicated extraction of a lower m olar, a distinct rise in the total leukocyte count in the first and second day and a gradual retu rn to norm al on the third day were observed. T h e relative and absolute num bers of neutrophils re­ sponded similarly, b u t the percentage of lymphocytes decreased. T h e packed cell volume h ad a slight b u t progressive de­ cline on the first, second, third and fourth days. I t has been previously established by Shannon and others3’4 th a t dental extrac­ tions cause stress and are accom panied by increases in the circulatory levels of adrenocortical steroids. M any types of surgery evoke systemic reaction, such as a polym orphonuclear leukocytosis, neutro­ philic leukocytosis, lym phocytopenia, in­ creased sedim entation rate and decreased packed cell volume. W e w anted to know w hether the peripheral blood would show these reactions 2 and 4 days after a simple qu ad ran t gingivectomy.

Control venous blood samples were col­ lected from ten hospitalized m en between 9 an d 10 a . m . on the day of operation, just before q u ad ran t gingivectomy. Blood samples w ere again taken 2 and 4 days later a t the same time of the m orning. Five of the patients were hospitalized for tuberculosis, 3 for neuropsychiatric disor­ ders, 1 for duodenal ulcer an d 1 for em ­ physema. Im m ediately after the blood had been draw n, a simple q u ad ran t gin­ givectomy was perform ed w ith the p a­ tient un d er local anesthesia (X ylocaine). A surgical pack (zinc oxide and eugenol base) was applied after the surgical p ro ­ cedure. T h ere was no prescaling, and the patients received no m edication. T h e table presents the results of ro u ­ tine clinical laboratory tests. D IS C U S S IO N

Clinical analysis of the w hite blood cells on the 2- and 4-day specimens showed no significant changes after the q u ad ran t gingivectomy. T h e white blood cell count is a sensitive indicator of systemic reac­ tions. O n the basis of these data, the peripheral blood seems not to reflect any significant systemic changes after gingi­ vectomy.

This observation is in contrast to the findings of Shannon, Davis and Gibson1 and Cheraskin2 who reported increased white blood cell count in patients under­ going an uncom plicated extraction of a m olar. T h e absence of leukocytosis after a gingivectomy indicated th at this p ar­ ticular operation did n o t seem to evoke body responses, as m easured by the num ­ ber of circulating white blood cells in the peripheral blood. Similarly, the percentage of neutro­ phils and lymphocytes rem ained constant. Again, significant changes indicate body responses, b u t such changes did not occur. T he erythrocyte sedim entation rate is perhaps the most sensitive index to body chemistry available to the clinician. The m ere extraction of a tooth causes an in­ crease of sedim entation rate through the fourth postoperative day. T he data in the table show a slight decrease 2 days and 4 days after the gingivectomy. This de­ crease is not statistically significant and. accordingly, the sedim entation rate did not change as a result of the gingivectomies. Packed cell volume and hemoglobin studies are useful in determ ining w hether a patient is anemic. T h e packed cell vol­ ume and hemoglobin determ ination taken 2 and 4 days postoperatively remained constant.

Blood studies did not reveal significant systemic changes after simple q u ad ran t gingivectomy. Specimens of the p eriph­ eral blood were taken from ten hospi­ talized m en before gingivectomy (control samples) and 2 and 4 days afterw ard. Leukocyte and differential neutrophil counts, erythrocyte sedim entation rate, packed cell volume and hemoglobin con­ centration were made. T h e findings from this study are in contrast to previous re­ ports of elevated sedim entation rate four days postoperatively in patients who had had uncom plicated extraction of a molar.
