Dataset Information

The association between periodontal diseases and halitosis among Saudi patients.

ABSTRACT:

Objectives

To assess the relationship between the presence of periodontal disease and halitosis.

Methods

A total of 120 patients were enrolled and divided into 2 groups, 60 patients with probing depth (PD) > 3.0 mm (group 1) and 60 patients with PD ? 3.0 mm (group 2). Clinical parameters including, plaque index (PI), bleeding index (BI), and PD were obtained. Breath samples were collected and analyzed using a portable gas chromatograph to measure the concentration of volatile sulfur compounds (VSC).

Results

Halitosis was found to affect 58.3% of the total patients. The means of PI, BI, and VSC were significantly higher in group 1 (PD > 3.0 mm) than in group 2 (PD ? 3 mm).

Conclusions

The percentage of patients suffering from halitosis in the Saudi population are comparatively high. In addition, there was a positive association between periodontal disease and halitosis.

Project description:Hepatitis B virus (HBV) infection is a leading cause of liver diseases including cirrhosis and hepatocellular carcinoma. Human leukocyte antigens (HLAs) play an important role in the regulation of immune response against infectious organisms, including HBV. Recently, several genome-wide association (GWAS) studies have shown that genetic variations in HLA genes influence disease progression in HBV infection. The aim of this study was to investigate the role of HLA genetic polymorphisms and their possible role in HBV infection in Saudi Arabian patients. Variations in HLA genes were screened in 1672 subjects who were divided according to their clinical status into six categories as follows; clearance group, inactive carriers, active carriers, cirrhosis, hepatocellular carcinoma (HCC) patients and uninfected healthy controls. Three single nucleotide polymorphisms (SNPs) belonged to HLA-DQ region (rs2856718, rs7453920 and rs9275572) and two SNPs belonged to HLA-DP (rs3077 and rs9277535) were studied. The SNPs were genotyped by PCR-based DNA sequencing (rs2856718) and allele specific TaqMan genotyping assays (rs3077, rs7453920, rs9277535 and rs9275572). The results showed that rs2856718, rs3077, rs9277535 and rs9275572 were associated with HBV infection (p = 0.0003, OR = 1.351, CI = 1.147-1.591; p = 0.041, OR = 1.20, CI = 1.007-1.43; p = 0.045, OR = 1.198, CI = 1.004-1.43 and p = 0.0018, OR = 0.776, CI = 0.662-0.910, respectively). However, allele frequency of rs2856718, rs7453920 and rs9275572 were found more in chronically infected patients when compared to clearance group infection (p = 0.0001, OR = 1.462, CI = 1.204-1.776; p = 0.0178, OR = 1.267, CI = 1.042-1.540 and p = 0.010, OR = 0.776, CI = 0.639-0.942, respectively). No association was found when polymorphisms in HLA genes were compared in active carriers versus cirrhosis/HCC patients. In conclusion, these results suggest that variations in HLA genes could affect susceptibility to and clearance of HBV infection in Saudi Arabian patients.
