Abstract

Bu çalışmanın amacı amalgam
dolgusu bulunan ve bulunmayan bireyleri tükürük civa(Hg) seviyeleri ve total antioksidan
aktiviteleri (TAA) arasındaki ilişkiyi incelemektir.

Çalışmaya 35 amalgam dolgulu
, 13 amalgam dolgusu toplam 48 birey katıldı.Amalgam dolgulu bireylerin
ağızlarından ölçü alındı ve restorasyonların yüzey alanları hesaplandı.Tüm
bireylerde uyarılmamış tükürük örnekleri toplanarak , tükürük Hg ve TAA
düzeyleri belirlendi.

Ortalama tükürük Hg
düzeyleri amalgam dolgulu bireylerde 21.41±26.07µg/l ,amalgam dolgusu
bulunmayan bireylerde 5.88±2.57µg /l olarak tespit edildi.Tükürük Hg
konsantrasyonlarınınamalgam dolgularının sayısıyla pozitif korelasyon
gösterdiği  ve dental amalgam olmayan
bireylerde istatistiksel olarak daha düşük olduğu belirlendi. (p<0.001)

Amalgam dolguların toplam yüzey
alanları veokluzal yüzey alanları ortalamaları ise sırayla 193.83±85.74 mm²
ve 153.90±64.87 mm²  olarak tespit edildi.İstatistiksel olarak
restorasyonların toplam alanları ile tükürük Hg seviyesi arasında bir
korelasyon bulunmamasına karşın ( p>0.05), restorasyonların yüzey alanları
ile tükürük Hg seviyesi arasında  pozitif
bir ilişki bulundu (p<0.05).

Ortalama TAA seviyeleri ise
amalgam dolgulu bireylerde 0.61±0.39 mmol/l, amalgam dolgusuz grupta ise
0,49±0.13 mmol/l idi.

Gerek amalgam dolgu sayısının
ve gerekse amalgam restorasyonlarının 
toplam ve okluzal alanlarının tükürük TAA konsantrasyonları ile bir
korelasyon göstrmediği saptandı( p>0.05).

Bu çalışmanın sonuçları
amalgam dolguların tükürükteki Hg’nin başlıca kaynaklarından biri olduğunu ve
bu restorasyonların okluzal yüzey alanlarının tükürük Hg düzeyi üzerinde etkili
bir unsur olmasına karşın. Bu etkinin tükürüğün TAA durumu üzerinde önemli
olmadığını gösterdi.

THE EFFECTS OF AMALGAM RESTORATIONS ON SALIVARY MERCURY CONCENTRATIONS AND TOTAL ANTIOXIDANT ACTIVITY

Abstract

The aim of the present study
was to examine the relationship between mercury (Hg) levels and Total
Antioksidant Activity (TAA) in saliva of subjects having amalgam restorations
and having not such fillings.

A total of 48 subjects
participated in this study , 35 whom hadamalgam restorations and the 13 had no
dental amalgams. In the amalgam group silicon impressions were taken and the
total surface and occlusal surface areas of filings were calculated.
Unsitimulated saliva samples of all subjects were collected and the levels of
Hg and TAA were determined.

The mean Hg concentrations
of saliva determined as 21.41±26.07µg/l in subjects with amalgam restorations,
and were 5.88±2.57µg /l in subjects without amalgams. Saliva Hg concentrations
were found to be positively correlated with the number of amalgam fillings and
were statistically lower in the group without dental amalgams . (p<0.001).
the mean total and occlusal surface areas of the amalgam fillings were
determined as 193.83±85.74 mm² and 153.90±64.87 mm2 , respectively.
Statically although there were no correlation between the total surface area of
the restorations and salivary Hg levels ( p>0.05),   a positive relationship were found between
the occlusal surface area of the amalgam fillings and Hg levels of saliva
(p<0.05).

The mean TAA levels were
0.61±0.39 mmol/l for amalgam group and 0,49±0.13 mmol/l for the non amalgam
group . It was found that neither the number of amalgam fillings nor the total
surface and occlusal surface area of the restorations did not correlated with
the salivary TAA concentrations ( p>0.05).

The results of the study
showed that although amalgam fillings were one the sources of Hg in saliva and
the occlusal surface area of these restorations were an effective factor on the
salivary Hg levels, These influences were not important on the TAA statusof the
saliva.
