A pilot case-control study of the association of vitamin D-related gene variants with peri-implantitis
This pilot case-control study investigated whether variants in vitamin D-related genes can be used to predict the occurrence of peri-implantitis. Eighty-two patients with at least one dental implant were enrolled. Thirty patients (36.6%) were diagnosed with peri-implantitis, whereas 52 (63.4%) had h...

| Summary: | This pilot case-control study investigated whether variants in vitamin D-related genes can be used to predict the occurrence of peri-implantitis. Eighty-two patients with at least one dental implant were enrolled. Thirty patients (36.6%) were diagnosed with peri-implantitis, whereas 52 (63.4%) had healthy peri-implant tissues. Clinical parameters, risk factors (history of periodontitis, smoking), and genetic factors were assessed. A buccal mucosa swab was taken for DNA analysis. Four variants in three vitamin D-related genes, VDR (rs2228570), retinoid X receptor alpha (RXRA) (rs3118523, rs7864987), and cytochrome P450 family 27 subfamily B member 1 (CYP27B1) (rs4646536) were genotyped by real-time PCR. There was no difference in the genotype distribution of the variants VDR rs2228570 (P=0.410), RXRA rs3118523, rs7864987 (P=0.789 and P=0.144, respectively), and CYP27B1 rs4646536 (P=0.562) between patients with healthy peri-implant tissues and those affected by peri-implantitis. History of periodontitis, a modified plaque index (mPI), modified bleeding index (mBI), peri-implant pocket depth, and implant location were associated with peri-implantitis incidence. In patients with peri-implantitis, CYP27B1 rs4646536 was associated with mBI (P=0.040), and RXRA rs7864987 was associated with implant position (P=0.009). We conclude that the variants of vitamin D-related genes, VDR, RXRA, and CYP27B1, cannot be used as molecular markers for peri-implantitis. |
