| Descripció: | Refractory periodontitis affects treatment success rates and may be associated with viral reservoirs in periodontal pockets. Human papillomavirus (HPV) causes direct cytopathic effects on periodontal tissues and may contribute to treatment failure. This study aimed to detect HPV in crevicular fluid and develop a risk stratification tool for patients with refractory periodontitis. A cross-sectional multicenter study was conducted involving 80 patients with refractory periodontitis from two Colombian universities. HPV detection was performed using conventional and real-time duplex PCR in crevicular fluid samples. Sociodemographic and clinical variables were analyzed. Multivariate logistic regression and ROC curve analysis were used to develop and validate a risk prediction score. HPV prevalence was 15% (12/80 patients), with high-risk genotypes identified in 4 cases (33% of HPV-positive). Multivariate analysis revealed oral sex practice as the strongest independent predictor (OR=18.9; 95%CI: 4.2-85.3, p<0.001), followed by female sex (OR=2.8; 95%CI: 0.6-13.1) and age >50 years (OR=4.2; 95%CI: 0.5-35.7). The developed risk score showed excellent discriminative capacity (AUC-ROC=0.85; 95%CI: 0.74-0.96) with 75% sensitivity and 82% specificity at optimal cutoff. HPV detection in crevicular fluid using our validated risk stratification tool may identify patients with refractory periodontitis requiring modified therapeutic approaches. The risk score provides a practical clinical tool for HPV screening in periodontal practice. |
