Association between chronic oral inflammatory burden and physical fitness in males: a cross-sectional observational study.

AIM: To evaluate the association between chronic oral inflammatory burden (OIB) - as the combination of periodontal and endodontic disease load - and physical fitness. METHODOLOGY: One hundred and twelve nonsmoker male police officers who performed a standardized physical fitness test (PFT) were analysed. Participants underwent oral clinical and periapical radiographic examinations. Periodontal disease was assessed by probing depth (PD) and clinical attachment loss (AL). For radiographic analysis, both apical periodontitis (AP) and root canal treatment (RCT) variables were analysed. Endodontic Burden (EB) was calculated merging the total number of teeth with AP and/or RCT per individual. OIB was calculated combining EB and AL. The outcome of physical fitness was dichotomized according to whether the highest PFT score was 'achieved' or 'not-achieved'. Multivariable logistic regression models were adjusted for age, body mass index and frequency of daily exercise. RESULTS: There was no significant association between AP, RCT and EB with physical fitness whereas PD, AL and OIB were significantly associated with low physical fitness (P < 0.05). Multivariate regression analysis revealed that individuals with OIB = EB ≥ 3 and AL ≥ 4 mm had a 81% lower chance of reaching the highest PFT score (OR = 0.19, 95%CI = 0.04-0.87, P = 0.03) compared to individuals with EB < 3 and and no AL ≥ 4 mm. Individuals with unfavourable periodontal parameters but with low EB (OIB = EB < 3 & AL ≥ 4 mm) showed no significant differences on the chance to reach the highest PFT score compared to participants with favourable periodontal status and low EB (OIB = EB < 3 & no AL ≥ 4 mm). CONCLUSIONS: The OIB - higher levels of EB in periodontal patients - was independently associated with poor physical fitness in males.

Extraoral implants for orbit rehabilitation: a comparison between one-stage and two-stage surgeries.

The aim of the study was to compare the osseointegration success rate and time for delivery of the prosthesis among cases treated by two-stage or one-stage surgery for orbit rehabilitation between 2003 and 2011. Forty-five patients were included, 31 males and 14 females; 22 patients had two-stage surgery and 23 patients had one-stage surgery. A total 138 implants were installed, 42 (30.4%) on previously irradiated bone. The implant survival rate was 96.4%, with a success rate of 99.0% among non-irradiated patients and 90.5% among irradiated patients. Two-stage patients received 74 implants with a survival rate of 94.6% (four implants lost); one-stage surgery patients received 64 implants with a survival rate of 98.4% (one implant lost). The median time interval between implant fixation and delivery of the prosthesis for the two-stage group was 9.6 months and for the one-stage group was 4.0 months (P < 0.001). The one-stage technique proved to be reliable and was associated with few risks and complications; the rate of successful osseointegration was similar to those reported in the literature. The one-stage technique should be considered a viable procedure that shortens the time to final rehabilitation and facilitates appropriate patient follow-up treatment.
