Adrenal incidentaloma as a novel independent predictive factor for periodontitis

PURPOSE

There are no data regarding periodontal derangements in patients with adrenal incidentalomas (AI). We assessed the frequency and severity of periodontitis in patients with AI [non-functioning adrenal incidentaloma (NFAI) and possible autonomous cortisol secretion (ACS)] and compared with individuals with normal adrenal.

METHODS

A cross-sectional study evaluated thirty-five individuals with AI and 26 controls. NFAI and possible ACS diagnosis was based on the current guidelines: NFAI [cortisol levels after 1 mg dexamethasone suppression test (1 mg-DST) ≤ 1.8 µg/dL (≤ 50 nmol/L)]; possible ACS [cortisol levels after 1 mg-DST 1.9-5.0 µg/dL (51-138 nmol/L)]. Sociodemographic data were collected, and a full-mouth periodontal evaluation was performed.

RESULTS

There was no significant difference between groups regarding age, sex, income, ethnicity, education level, smoking, body mass index, dysglycemia, and arterial hypertension. Patients with AI exhibited worse periodontal conditions than controls for the following periodontal clinical parameters: mean percentage of probing pocket depth (PPD) and clinical attachment level (CAL) ≥ 5 mm (p < 0.001 and p = 0.006, respectively). Patients with NFAI and possible ACS showed higher gingival bleeding index (p = 0.014), bleeding on probing (p < 0.001), and CAL (p < 0.001) means compared to controls. The frequencies of periodontitis were 72.7% in patients with NFAI, 84.6% in possible ACS, and 30.8% in controls (p = 0.001). Periodontitis was more severe in patients with possible ACS than NFAI and controls. Patients with NFAI and possible ACS exhibited odds ratio for periodontitis of 4.9 (p = 0.016) and 8.6 (p = 0.02), respectively.

CONCLUSION

Patients with AI have higher frequency and severity of periodontitis than controls. The presence of AI was an independent predictive factor for periodontitis.

An investigation of the bidirectional link between osteoporosis and periodontitis

This study investigated whether periodontitis affects systemic bone status and whether FRAX® is a screening tool for periodontal disease in elderly women. The findings showed that bone density was not influenced by periodontitis and highlighted that women with FRAX® score above the intervention threshold had greater chance to present severe periodontitis.

PURPOSE

This study investigated whether periodontal disease is a predictor for systemic bone loss among elderly women. The utilization of FRAX® as a screening tool for severe periodontitis was also evaluated in this population.

METHODS

Current bone mineral density (BMD) for lumbar spine and proximal femur was used as an indicator of "bone status." Number of interdental sites with severe clinical attachment loss, frequency of bleeding on probing, and percentage of tooth loss due to periodontitis represented "periodontal disease" that was tested as a predictor of bone loss in a structural equation modeling analysis involving 110 participants. The intake of antiosteoporosis medication was considered in the analysis. Four other different criteria for periodontitis classification were also tested. FRAX® for major fracture was calculated without BMD, and with intervention threshold set by age. Longitudinally, BMD changes up to 10 years were also obtained and checked for possible association with periodontitis.

RESULTS

Periodontal disease was not a predictor for worse systemic bone status according to the different periodontal disease classifications, and was not associated with BMD changes. Antiosteoporosis medication directly predicted periodontal disease and systemic bone status. Women with FRAX® score above the intervention threshold had higher chance for periodontitis in more advanced stages: III/IV (OR = 1.13, 95% CI [1.04 to 1.22], p = 0.03).

CONCLUSION

Periodontal disease did not constitute a predictor for reduced systemic bone density in the studied population of elderly women. On the other hand, FRAX® demonstrated to be a useful tool to suggest periodontal evaluation. Antiresorptive medication showed benefits on periodontal and bone status.

Effects of Bone Fragility and Antiresorptive Drugs on Periodontal Disease and Tooth Loss: A Longitudinal Study

This longitudinal study aimed to elucidate whether systemic bone fragility predicts severe periodontal clinical attachment loss (CAL) and tooth loss over the years and to test the influence of bone medication and periodontal maintenance in these relationships. Elderly women were evaluated for bone mineral density (BMD) and for fracture risk assessment (FRAX) in a cross-sectional analysis and retrospective follow-up (6- and 10-y periods). Data on BMD and FRAX were used as indicators of bone fragility in structural equation modeling. Periodontal examination and data on postmenopausal tooth loss were recorded. Multivariate Poisson regression models with robust covariance were used to estimate relative risk (RR) and 95% CI of BMD and FRAX for sites with CAL ≥6 mm and for tooth loss. The cross-sectional analysis included 134 women aged 65 to 80 y, and from them 71 and 49 women had available data for analysis in the 6- and 10-y follow-up periods, respectively. Bone fragility predicted severe CAL over 10 y (e.g., femoral neck: 10-y analysis, β = -0.389, P = 0.005; cross-sectional, β = -0.190, P = 0.004); however, this association did not remain significant when the use of bone medication was evaluated. Poisson regression showed that a better skeletal condition was associated with a lower risk of severe periodontal disease and tooth loss (cross-sectional femoral neck: RR = 0.08, P < 0.001; RR = 0.03, P < 0.001, respectively) when not adjusted for bone medication and periodontal maintenance. The receiver operating characteristic curve suggested that women with osteoporosis should be referred for periodontal assessment (sensitivity = 71.0%, specificity = 70.0%). Bone fragility is a relevant longitudinal predictor of severe periodontal disease and tooth loss among elderly women. The use of bisphosphonates improved the bone condition as well as the periodontal status. Periodontal maintenance also minimized the negative impact of low BMD on teeth-supportive tissues in the studied population. Knowledge Transfer Statement: The results of this study present evidence that the management of bone fragility and osteoporosis may be important in the prevention of periodontal attachment loss and future tooth loss. Besides the antiresorptive effects of the antiosteoporosis drugs on systemic bone conditions, these medications may protect periodontal tissues. The interaction of health care professionals such as dentists and physicians represents a key role for the approach to women's health, especially in an aging world.

Association of osteoporosis and bone medication with the periodontal condition in elderly women

This study investigated whether osteoporosis and its treatment may affect periodontal condition in elderly women. The findings highlighted that women with osteoporosis had a higher chance to present severe periodontitis than women with normal bone mineral density (BMD), particularly those who were not treated for osteoporosis.

INTRODUCTION

This study investigated whether osteoporosis increases the frequency and severity of chronic periodontitis in elderly women and evaluated the influence of vitamin D and osteoporosis treatment in the periodontal condition.

METHODS

In this cross-sectional study, elderly women were selected among 1266 subjects evaluated for lumbar spine and proximal femur bone mineral density (BMD) using dual energy X-ray absorptiometry. Sociodemographic, clinical characteristics, and complete periodontal examination were recorded. Serum 25-hydroxyvitamin D levels were measured by chemiluminescence.

RESULTS

Forty-eight elderly women with normal BMD and 86 with osteoporosis were selected. Women with osteoporosis presented higher frequency of sites with clinical attachment level ≥6 mm (p = 0.003) and gingival recession ≥3 mm (p = 0.002) than those with normal BMD and were more than twice as likely to present severe periodontitis (odds ratio (OR) = 2.49, 95 % CI [1.14 to 5.43]). Osteoporotic women who were not treated for the condition had more chance to present severe periodontitis (OR = 3.16, 95 % CI [1.28 to 7.82]) than those who did use bisphosphonates (OR = 2.04, 95 % CI [0.85 to 4.89]). Among the participants who presented low levels of vitamin D, those with osteoporosis exhibited a higher chance to present severe periodontitis than those with normal BMD (p = 0.027), but the association between vitamin D levels and osteoporosis was not statistically significant after adjustment (p = 0.198).

CONCLUSIONS

Elderly women with osteoporosis have a greater chance to present periodontitis, with higher severity than those with normal BMD. Osteoporosis treatment provides protection for periodontitis.

The influence of stress and anxiety on the response of non-surgical periodontal treatment

AIM

The aim of this study was to evaluate the influence of stress and anxiety on the response to non-surgical periodontal treatment (NPT) in patients with chronic periodontitis.

METHOD

Sixty-six patients (mean age 46.1 +/- 8 years) were assigned to three groups: control group, probing pocket depth (PPD) <or=4 mm, n=20; T1, at least four sites with PPD >or=4 and <or=6 mm, n=26; and T2, at least four sites with PPD >6 mm, n=20. Stress, state anxiety (SA) and trait anxiety (TA) and plaque index (PI), gingival index, PPD and clinical attachment level (CAL) were recorded at baseline and 3 months after NPT.

RESULTS

TA scores were different among groups at baseline and after NPT. TA was related to periodontitis at baseline and after NPT. PI was associated with the SA at baseline. The reduction of frequency of CAL >6 mm was correlated with TA after adjusting for confounders. Stressed subjects did not show reduction of frequency of PPD >6 mm (T1), CAL 4-6 mm and CAL >6 mm (T2).

CONCLUSIONS

The data suggest an influence of trait of anxiety and stress on the response to NPT.

The relationship of stress and anxiety with chronic periodontitis

AIM

This case-control study investigates the relationship of stress and anxiety with periodontal clinical characteristics.

METHOD

Seventy-nine selected patients (mean age 46.8+/-8 years) were assigned to three groups in accordance with their levels of probing pocket depth (PPD): control group (PPD< or =3 mm, n=22), test group 1 (at least four sites with PPD > or =4 mm and < or =6 mm, n=27) and test group 2 (at least four sites with PPD >6 mm, n=30). An inclusion criterion of the study required that patients presented a plaque index (PI) with a value equal to or larger than 2 in at least 50% of dental surfaces. All subjects were submitted to stress and anxiety evaluations. Stress was measured by the Stress Symptom Inventory (SSI) and the Social Readjustment Rating Scale (SRRS), while the State-Trait Anxiety Inventory (STAI) was used to assess anxiety. Clinical measures such as PI, gingival index (GI), PPD and clinical attachment level (CAL) were collected. Patient's medical history and socioeconomic data were also recorded.

RESULTS

The mean clinical measures (PI, GI, PPD and CAL) obtained for the three groups, were: control group, 1.56+/-0.32, 0.68+/-0.49, 1.72+/-0.54 and 2.04+/-0.64 mm; group 1, 1.56+/-0.39, 1.13+/-0.58, 2.67+/-0.67 and 3.10+/-0.76 mm, group 2, 1.65+/-0.37, 1.54+/-0.46, 4.14+/-1.23 and 5.01+/-1.60 mm. The three groups did not differ with respect to percentage of clinical stress, scores of the SRRS, trait and state anxiety. Frequency of moderate CAL (4-6 mm) and moderate PPD (4-6 mm) were found to be significantly associated with higher trait anxiety scores after adjusting for socioeconomic data and cigarette consumption (p<0.05).

CONCLUSIONS

Based on the obtained results, individuals with high levels of trait anxiety appeared to be more prone to periodontal disease.
