Oral health related qualıty of lıfe and dısease severıty ın autoımmune bullous dıseases

Background

There is an increased risk of long-term dental and periodontal disease in autoimmune bullous diseases (AIBD).

Aims

In this cross-sectional study, we aimed to determine whether the oral health-related quality of life status (OHRQoL) was associated with disease severity and activity in patients with AIBD.

Subjects and Methods

67 patients with AIBD were enrolled in this study. Autoimmune Bullous Skin Disorder Intensity Score (ABSIS) was used to evaluate the disease severity. The score was categorized as a significant course (≥17) and moderate course (<17). Oral health impact profile-14 (OHIP-14) questionnaire was filled to assess the OHRQoL. Self-reported oral health status and oral lesion related pain score were also evaluated in the study group.

Results

OHIP-14 score was significantly higher in active patients (42.28 ± 13.66) than inactive patients (29.08 ± 12.25) (P = 0.004) and it was correlated with the pain score (6.33 ± 2.78; r = 0.409, P = 0.013). Furthermore, OHIP-14 score was higher in patients with a significant disease course (45.18 ± 15.08) (P = 0.010) than in patients with a moderate course (36.09 ± 9.73).

Conclusions

OHRQoL may be useful in the disease management and treatment. Since it can be affected by both presence of oral erosions and disease severity, a collaboration between dermatologists and dentists could be crucial to the disease management in AIBD.

An In-vitro study on thermal changes during implant drilling with different irrigation volumes

Objective

Irrigation with saline is one of the essential methods for reducing the heat generated during dental implant osteotomy. High irrigation volume impairs visibility of the surgical field, thus complicates the surgery. In this study, we aimed to determine the optimal irrigation volume for heat reduction during dental implant drilling.

Materials and Methods

Thirty-two implant osteotomies were prepared on four fresh cow ribs. Heat generated during the final implant drilling was measured both with infrared thermography and thermocouple method. Initial and maximum temperatures were measured at four different irrigation volumes; 32, 44, 56, and 68 ml/min.

Results

Both measurement methods showed that the amount of temperature rise is associated with the irrigation volume during implant drilling. There is no further decrease in temperature rise above irrigation volume of 56 ml/min.

Conclusion

Saline irrigation with 56 ml/min provides sufficient heat reduction during dental implant drilling and higher irrigation volumes are not necessary.

Salivary infectious agents and periodontal disease status

BACKGROUND AND OBJECTIVES

The potential of salivary microorganisms to diagnose periodontal disease and to guide periodontal treatment is a research topic of current interest. This study aimed to determine whether the salivary counts of periodontopathic microbes correlated with the periodontal pocket counts of the same infectious agents, and whether the salivary counts of the test infectious agents could distinguish among individuals with periodontal health and various types of periodontal disease.

MATERIAL AND METHODS

The study included 150 systemically healthy adults, of whom 37 were periodontally healthy, 31 had gingivitis, 46 had chronic periodontitis and 36 had aggressive periodontitis. Each study subject contributed microbial samples from the two deepest periodontal pockets of the dentition and from whole saliva. Aggregatibacter actinomycetemcomitans, Campylobacter rectus, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia and Epstein-Barr virus were identified using the TaqMan real-time PCR methodology. Statistical analysis was performed using the Mann-Whitney U-test and the receiver operating characteristic statistics.

RESULTS

C. rectus, F. nucleatum, P. gingivalis, P. intermedia and T. forsythia occurred with significantly higher copy-counts in salivary samples from patients with gingivitis, chronic periodontitis and aggressive periodontitis than from periodontally healthy individuals. A. actinomycetemcomitans only showed higher salivary copy-counts in subjects with aggressive periodontitis compared with subjects with healthy periodontium, and the salivary copy-counts of Epstein-Barr virus did not reveal any significant difference among the four subject groups studied. The diagnostic sensitivity for periodontitis was 89.19 for P. gingivalis and for T. forsythia and 86.49 for P. intermedia, with specificities ranging from 83.78 to 94.59. The optimal copy-counts per mL saliva for identifying periodontitis were 40,000 for P. gingivalis, 700,000 for T. forsythia and 910,000 for P. intermedia.

CONCLUSION

Salivary copy-counts of P. gingivalis, T. forsythia and P. intermedia appear to have the potential to identify the presence of periodontitis, whereas the salivary level of the other test infectious agents may possess little or no diagnostic utility. Longitudinal studies are warranted to determine the ability of salivary copy-counts of major periodontopathic bacteria to predict future periodontal breakdown.
