ABSTRACT

Background: Cervical end preparation is an important procedure in fixed partial denture, becauseif it is inadequate it will increase dental plaque accumulation which is the beginning of periodontal disease. Purpose: The aim of this study was to analyze the effect of cervical endpreparation design on collarless metal ceramic crown to the level of IL-1 in gingival crevicefluid (GCF). Method : the study was carried out using by quasi experimental with pre and posttest with contol grup design involving 48 subjects. The tooth preparation and the cervical endpreparation were made with shoulder, beveled shoulder, and deep chamfer cervical endpreparation. The assessment of IL-1 in GCF was measured before and 1,7, 21 days after insertion of collarless metal ceramic crown. Result : This study showed that the increase of levelIL-1 in GCF on bevel shoulder and deep chamfer was significant different compared withcontrol group (p

groups that are shoulder, beveled shoulder, and deep chamfer cervical end, respectively 8 teeth.Control consisted of 24 contralateral teeth. Culture of the bacteria was made before teethpreparation, and on the 1 st. 7 th, and 21 st day after insertion of the crown. Data was analyzed by t-test and chi square.

Table 1 showed that on the 7 th day, there was a significant difference of the level of IL-1in GCF between the treatment group and the control only in the bevel shoulder design (p< 0,05).Whereas the 21 st day, there was a significant difference found in the level of IL-1 in GCF inbevel shoulder and deep chamfer design (p< 0,05).

Table 2 showed that on the 7 th day, significant difference of IL-1 happened between thetreatment group and the control group only in bevel shoulder preparation design (p< 0,05).Whereas on the 21 st day, there was a significant difference of IL-1 level in bevel shoulder preparation and deep chamfer design (p< 0,05).

DISCUSSION

The process of the inflammation include the entry of white blood cells, complement,antibodies and protein plasma to the infection or lesion area to maintain it self. 3,4 Inflammationwas the reaction of the body to the entry of the foreign object, micro-organisms or tissue damage.To destroy the foreign object, the body will move the elements of the immune system to the areaof the inflammation. 5

The inflammation in gingival could be classified on acute, sub-acute, and chronicinflammation. The vascular response in the lesion was basic for reaction of the acuteinflammation. Without adequate blood supplies, reaction of inflammation could not happen. The

vascular change could be divide into two, those are blood flow and vascular permeability.6

In adequate cervical margin design preparation (deep chamfer and bevel shoulder preparation) the plaque bacteria will patch easily and cause the inflammation to this area. To becontrary with shoulder preparation design, which has good adaptation of the teeth cervicalmargin to the crown cervical margin restoration, until the plaque could not adhere to this area.


4/5

Shoulder preparation design, in this research, did not increase the level of IL-1 in GCF,because the margin was so close, so could prevent the bacteria invade into gingival. Other resultsshowed that cervical margin preparation design of beveled shoulder and deep chamfer couldincrease the level of IL-1 in GCF that caused immunologic reaction. Immunologic reaction willstimulate macrophage to trigger IL-1 and migrated into GCF, caused the emergencesinflammation reaction in gingival. 1,5

CONCLUSION

Design of cervical margin preparation could increase the level of IL-1 in GCF. Shoulder is a best cervical end preparation design for collarless metal ceramic crown restoration.
