Abstract:
Introduction: Changes in female sex hormone levels during pregnancy are related to the
increased sensitivity to gingival inflammation. This phenomenon, also named pregnancy-related
gingivitis, Gingivitis Gravidarum, usually occurs with an association of dental plaque, and develops
more severe forms, in comparison to plaque-induced gingivitis in non-pregnant women.
Purpose and Objectives: Determining the prevalence and severity of gingival inflammation
at different period of gestation, estimating Oral Hygiene Indexes.
Materials and methods: The study was based on the examination of periodontal state of 30 pregnant women (1 8 -3 5 years old). The sample was divided according to the trimesters into 3 subgroups:
Group 1: includes 6 women at 1st trimester.
• Group 2: includes 11 women at 2nd trimester.
• Group 3: includes 13 women at 3rd trimester.
A questionnaire was taken from all pregnant women. The examination was done in a dental
clinic using periodontal probe and dental mirror, estimating oral hygiene index "OHI" G. Green, J.
Wermillion, gingival index by Loe H. and Silness, papillary bleeding index (Mtihlemann).
Results: It was revealed that the prevalence of gingivitis was 63,3 % (19 persons) in the
studied sample. It was determined that the severity of the inflammation is exacerbating during the
2nd month of pregnancy reaching a peak at the 8th month. Gingival bleeding occurred in 52,6% of
cases in the first trimester, and in 47,4 % in the second trimester. The results showed that 31,5% of
the total sample had gingival recession and that the affected teeth are upper and lower incisors and
canines. Regarding the tooth surface, it appears that facial surface was more affected than the
gingival or palatal surfaces. The prevalence of plaque was 73% among all subgroups with nonsignificant differences. The direct relationship between the frequency of brushing and the incidence
of gingivitis gravidarum shows that the condition can be minimized by better oral hygiene. The
pregnant women were instructed to use a dentifrice with 0.30% triclosan, an antimicrobial
compound. Self-performed tooth brushing with a triclosan/copolymer-containing toothpaste
improves the daily plaque control and reduces the gingivitis formation significantly.
Conclusion: The importance of local factors in gingivitis in pregnancy cannot be minimized,
but the role played by systemic disturbances due to changes in hormonal balance must be
considered. The local treatment in a preventive oral hygiene program from early pregnancy is very
important to prevent further progression of any inflammation.
