Periodontitis and bone mineral density among pre and post menopausal women: A comparative study

ALVEOLAR BONE PATTERN AND SALIVARY LEPTIN LEVELS AMONG PREMENOPAUSAL OBESE WOMEN

BACKGROUND

Systemic bone loss may lead to more severe periodontal destruction, decreasing local bone mineral density.

AIM

A cross-sectional designed was performed to study associations among alveolar bone pattern, salivary leptin concentrations, and clinical periodontal status in premenopausal obese and eutrophic women.

METHODS

Thirty morbid obese (G1) and 30 normal-weight (G2) women were included. Anthropometric and periodontal measurements (probing depth - PD, clinical attachment levels - CAL, presence of calculus, bleeding on probing -BOP, and plaque accumulation) were assessed. OHIP-14 was used for assessment of oral health impact on quality of life. Panoramic radiography was used to obtain the panoramic mandibular index (PMI), mandibular cortical index (MCI), and mental index (MI). Intraoral periapical (PA) radiography was taken to measure the total trabecular bone volume. Leptin was measured in saliva of fasted overnight women.

RESULTS

Groups 1 and 2 differed in all anthropometric aspects, but height. Pocket depth, calculus, BOP, and plaque index were worse in G1. No differences between groups were found considering OHIP. Normal-weight subjects showed higher proportion of dense bone trabeculae than obese subjects for pre-molars, but not for molars. Mental and panoramic mandibular indexes did not differ and were in normal level. Leptin concentration was dependent only on BMI.

CONCLUSION

Obesity affected the periodontal conditions, the alveolar bone pattern, and the salivary leptin concentration.

Effect of nonsurgical periodontal therapy on plasma-reactive oxygen metabolite and gingival crevicular fluid resistin and serum resistin levels in obese and normal weight individuals with chronic periodontitis

Background:

The hyperoxidative and a modified inflammatory state in obese individuals cause higher susceptibility to bacterial infection which influences the initiation and progression of periodontal disease.

Aim:

Our study was aimed to evaluate the role of nonsurgical periodontal therapy on the clinical parameters such as gingival index (GI), plaque index, pocket probing depth (PPD) and clinical attachment level (CAL), plasma-reactive oxygen metabolite (ROM) levels, and gingival crevicular fluid (GCF) resistin and serum resistin levels in obese or overweight and normal weight individuals with periodontitis.

Material and Methods:

Sixty individuals of age between 35 and 45 years of both the sexes were selected and categorized into two groups as thirty overweight or obese individuals with chronic periodontitis (Group I) and thirty normal weight individuals with chronic periodontitis (Group II). Clinical parameters, plasma ROM levels, and serum and GCF resistin levels were assessed at baseline and 2 months after periodontal therapy in both the groups and compared.

Results:

Intergroup comparison of clinical parameters (GI, CAL, PPD) 2 months after therapy showed a significant difference with more reduction in Group II compared to Group I. On comparison, mean plasma ROM, GCF, and serum resistin levels at baseline was higher in Group I compared to Group II. When plasma ROM, GCF, and serum resistin levels were compared 2 months after therapy, the reduction was more in Group II compared to Group I.

Conclusion:

It is concluded that along with periodontal therapy, motivation of patients for weight reduction program is mandatory for obese or overweight individuals with periodontitis in order to improve periodontal health.

A Cross-Sectional Study to Assess and Correlate Osteoporosis and Periodontitis among Postmenopausal Women: A Dual Energy X-Ray Absorptiometry Study

Background:

Periodontitis and osteoporosis are two diseases found worldwide and increase in intensity with increasing age of the patients. The severity of osteoporosis and periodontitis are found to be more in women during menopause. The aim of this study was to assess and correlate osteoporosis and periodontal disease among post-menopausal women.

Materials and Methods:

The study consisted of 94 postmenopausal women in the age range of 45–65 years. All the women underwent dual-energy X-ray absorptiometry (DXA) scan to measure bone mineral density (BMD) and were graded as normal, osteopenic, and osteoporotic based on the T score obtained. Data regarding patient's educational level, socioeconomic status (SES), and body mass index (BMI) was recorded. A detailed periodontal examination was carried out using clinical parameters such as oral hygiene index (OHI), plaque Index (PI), probing pocket depth , and clinical attachment loss to check the level of periodontitis. The level of osteoporosis was correlated with the level of periodontitis.

Results:

The DXA scan revealed that four women were normal, 44 were osteopenic and 46 were osteoporotic. There was no association found between BMD and OHI, PI, educational status, SES, and BMI. Slight periodontitis was observed in eight women, moderate periodontitis in 62, and severe periodontitis in 24 women. Result suggests that there was a statistical correlation between periodontitis and osteoporosis (P = 0.045).

Conclusion:

There is a definite correlation found between the severity of periodontitis and osteoporosis among postmenopausal women. A close cooperation between general practitioners and dentists in early diagnosis and treatment of both the diseases will reduce the risk and morbidity among postmenopausal women.

Comparative analysis of subgingival red complex bacteria in obese and normal weight subjects with and without chronic periodontitis

BACKGROUND

Obesity is one of the systemic conditions which influence the onset and progression of periodontal disease and it is stated that the metabolic changes associated with obesity may contribute to alteration in subgingival microbial flora.

AIM

Our study was aimed to quantify and compare the red complex microorganisms in obese or overweight and normal weight participants with and without chronic periodontitis to identify obesity as a risk for the presence of red complex bacteria.

MATERIALS AND METHODS

The study group consisted of 120 participants of age between 20 and 45 years of both the sexes. According to periodontal status, the participants were categorized into four groups as follows: thirty overweight or obese individuals with generalized chronic periodontitis (Group I), thirty normal weight individuals with chronic periodontitis (Group II), thirty overweight or obese individuals with healthy periodontium (Group III), and thirty normal weight individuals with healthy periodontium (Group IV). After the assessment of periodontal parameters, subgingival plaque sample collection was carried out to quantify the red complex bacteria by real-time polymerase chain reaction.

RESULTS

Increase in red complex bacterial count was seen in group I compared to other groups. A positive correlation of red complex bacteria with body mass index and waist circumference was seen in Group I and III.

CONCLUSION

In our study, obese individuals with periodontal disease harbored increased red complex bacteria. This states that the obesity could be a risk for the colonization of red complex microorganisms, which in turn may further lead to periodontal inflammation.

Comparison of bone mineral density among pre- and post-menopausal women with and without chronic generalized periodontitis

Background

There have been a very limited number of studies regarding the assessment of bone mineral density (BMD) using dual energy X-ray absorptiometry scan. Hence, the purpose of the study was to assess the relationship between BMD and periodontal health in three different study groups.

Materials and Methods

The study comprised of thirty female individuals who were categorized into three groups: ten premenopausal women with healthy periodontium (Group A), ten premenopausal women with generalized chronic periodontitis (Group B), and ten postmenopausal women with generalized chronic periodontitis (Group C). Number of teeth, plaque index, probing depth, clinical attachment level, interproximal alveolar bone loss, T-score for dual femur and posteroanterior (PA) spine, and BMD for dual femur and PA spine of each individual were recorded in all the three groups.

Results

The BMD and T-score of dual femur and PA spine were found to be low in Group C when compared to Group A and B which was statistically significant.

Conclusion

Postmenopausal women with generalized chronic periodontitis (Group C) exhibited severe periodontal destruction with less BMD. Hence, it is suggested that periodontitis may be a risk indicator for osteoporosis in postmenopausal women and vice versa.

Association between osteoporosis and periodontal disease among postmenopausal Indian women

AIM

The aim of the present study was to determine the association between osteoporosis and periodontal disease among postmenopausal Indian women.

METHODS

A cross-sectional comparative study was conducted among postmenopausal women aged 45-65 years attending various hospitals in Bangalore, India. The examination was performed using the plaque index, gingival index, modified sulcus bleeding index, and community periodontal index. The women then underwent a bone mineral density (BMD) test using an ultrasonometer. Based on the BMD scores, participants were divided into osteoporotic and non-osteoporotic groups. For the statistical analysis, χ² -test, Student's t-test, and multiple regression analysis were applied.

RESULTS

The mean plaque, gingival, and bleeding scores were significantly higher among osteoporotic women (1.83 ± 0.47, 1.73 ± 0.49, 1.82 ± 0.52) compared to the non-osteoporotic women (1.31 ± 0.40, 1.09 ± 0.52, 1.25 ± 0.50). The mean number of sextants affected for codes 3 and 4 of the community periodontal index and codes 1, 2, and 3 of loss of attachment were significantly higher among osteoporotic group compared to the non-osteoporotic group. Multiple logistic regression tests confirmed the statistically-significant association between osteoporosis and menopause duration, loss of attachment, bleeding, and gingivitis scores.

CONCLUSIONS

Skeletal BMD is related to clinical attachment loss, bleeding, and gingivitis, which suggests that there is an association between osteoporosis and periodontal diseases.

A Study to Assess and Correlate Osteoporosis and Periodontitis in Selected Population of Maharashtra

BACKGROUND

Osteoporosis is a systemic bone disorder characterized by decreased bone mass and increased risk for fracture. It has been proposed as a possible risk factor for periodontal disease progression. Recent literature has shown periodontitis to be a risk indicator for osteoporosis, suggesting a possible two way relationship. However the association between these two diseases still remains unclear leading to a scope of further research in this area.

AIM

The aim of the present study was to assess and Correlate the severity of osteoporosis and periodontitis by using variables like probing pocket depth, clinical attachment loss, plaque index, body mass index and bone mineral density.

MATERIALS AND METHODS

A total of 65 subjects aged between 45-75 years suffering from periodontitis were considered. All subjects were assessed for periodontal disease severity by plaque index (PI), probing pocket depth (PPD) and clinical attachment loss (CAL). The bone mineral density (BMD) of patients was assessed using dual energy X- ray absorptiometry (DXA) at lumbar spine (L1 - L4). The severity of periodontal disease was correlated with severity of osteoporosis. Descriptive statistics like frequency and percentage were calculated for all the variables. Chi-square test was performed to assess the association between the study variables.

RESULT

Among the entire group 78.46% had high plaque index score, and the severity of periodontitis increased with increase in plaque index score showing a statistical significance. Osteopenia was observed in 25.33% of the subjects, out of whom 63.15% suffered from severe periodontitis. Osteoporosis was observed in 17.33% of the subjects, and all the subjects (100%) suffered from severe periodontitis.

CONCLUSION

The results of the present study suggest that increasing severity of periodontitis increased the risk of osteoporosis and vice versa. We conclude that there is a definite association between periodontitis and osteoporosis.

The association between periodontal disease, tooth loss and bone mineral density in a Korean population

OBJECTIVE

We aimed to evaluate whether clinical attachment loss (CAL), a measure of the severity of periodontal disease or number of teeth present is associated with bone mineral density (BMD).

METHODS

The study population consisted of 5383 people aged 50 years and older who participated in the Dong-gu Study. BMD at the lumbar spine and femoral neck was measured by dual-energy X-ray absorptiometry. Oral examination included assessments of the number of teeth present and CAL. Number of teeth present was categorized into three equal categories. CAL values were divided into tertiles in terms of the percentage of sites with CAL ≥4 mm. Analysis of covariance was used to compare the adjusted means of BMD according to the tooth number and the tertiles of CAL.

RESULTS

There was a significant association between the number of teeth present and BMD in men. Compared with men with 22 or more teeth, men with 10 and less teeth had lower BMD. CAL was significantly associated with lower BMD at the lumbar spine in women.

CONCLUSION

Our data indicate that tooth loss and CAL were associated with low BMD. However, the magnitude of these associations was relatively small and the clinical significance was unclear.

Risk factors of periodontal disease: review of the literature

Objectives. This paper aims to review the evidence on the potential roles of modifiable and nonmodifiable risk factors associated with periodontal disease. Data. Original articles that reported on the risk factors for periodontal disease were included. Sources. MEDLINE (1980 to Jan 2014), PubMed (using medical subject headings), and Google Scholar were searched using the following terms in different combinations: "periodontal disease," "periodontitis," "risk factors," and "causal." This was supplemented by hand-searching in peer-reviewed journals and cross-referenced with the articles accessed. Conclusions. It is important to understand the etiological factors and the pathogenesis of periodontal disease to recognize and appreciate the associated risk factors. As periodontal disease is multifactorial, effective disease management requires a clear understanding of all the associated risk factors.

Biochemical markers as predictors of bone remodelling in dental disorders: a narrative description of literature

Osteoporosis is a systemic disease in which the skeletal condition is characterized by a decreased mass of normally mineralized bone, due to an augmentation of bone resorption processes. Bone biomarkers serum are used for the diagnosis. On the other hand the main cause of the resorption in the bone jaws are periodontitis, inflammatory cysts, developmental cysts, odontogenic neoplasms. Periodontal diseases can be localized to a single site of the jaws or can affect all the teeth, with a massive bone resorption. The cysts are classified in developmental and inflammatory. They caused a local bone resorption in the jaws. Keratocystic odontogenic tumor produces a large bone resorption for its local aggressive nature. Their diagnosis is clinical and radiological.The aim of our review is to find a correlation between bone biomarkers serum and periodontitis, inflammatory cists, developmental cysts, odontogenetic neoplasms.The RANK/RANKL/OPG system is the most studied not only in osteoporosis but also in the periodontitis, inflammatory cysts, developmental cysts, odontogenic neoplasms. In the last years osteoimmunology was used to study the periodontal disease progression, because the immunity cells start the bone resorption processes.A lot of studies analyze the biomarkers present in the biofluids, as saliva and gingival crevicular fluid, but not the correlation with serum biomarkers.Future studies must be organized to deepen the correlation between bone biomarkers and bone jaws resorption and to allow diagnosis and prognosis of periodontitis, inflammatory cysts, developmental cysts, odontogenic neoplasms.

Oral microcirculation in post-menopause: a possible correlation with periodontitis

OBJECTIVES

The reduction in the level of oestrogen, typical in menopause, has some effect on the health of the oral cavity. In fact, post-menopausal women present more severe periodontal disease than pre-menopausal women. Numerous factors can be held to be responsible for this increase, among which are the effects of oestrogens on the oral epithelium, on the salivary glands, on bone tissue and on the endothelium. Our double blind study aims to evaluate the possible variations in oral microcirculation in post-menopausal women.

METHODS

Twenty-seven women in post-menopause (age: Mean ± SD: 57.3 ± 8.73) and 27 women in pre-menopause (age: Mean ± SD: 27.77 ± 3.56) were examined. Oral microcirculation was investigated using oral videocapillaroscopy.

RESULTS

The study showed significant differences between cases and controls for the following parameters: decrease in diameter of loops (mean ± SD: 0.038 ± 0.008; 0.045 ± 0.005), increase in tortuosity (mean ± SD: 3.83 ± 1.13; 1.83 ± 1.06) in labial mucosa and decrease in density in periodontal mucosa (Mean ± SD: 28.86 ± 10.92; 89.62 ± 17.83).

CONCLUSION

The decrease in periodontal density may compromise the epithelium tropism, making it prone to inflammation. The tortuosity may indicate a greater permanence of inflammatory factors, increased in post-menopausal women.
