Doughan M, Chehab O, Doughan B, Lima JAC, Michos ED. Association of endogenous sex hormone levels with tooth loss due to periodontitis in men and post-menopausal women: The multi-ethnic study of atherosclerosis. J Periodontal Res 2024. [PMID: 38895935 DOI: 10.1111/jre.13312] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 05/25/2024] [Accepted: 05/27/2024] [Indexed: 06/21/2024]
Abstract
AIM To investigate the association between endogenous sex hormone levels and history of tooth loss related to periodontitis in healthy middle-aged to older men and post-menopausal women. METHODS This cross-sectional study included 5649 participants aged 45-84 (mean age, 63 ± 10 years) from the Multi-Ethnic Study of Atherosclerosis cohort who had sex hormone levels measured and answered a questionnaire regarding perceived periodontal status at exam 1. Multivariable logistic regression was used to examine the association of sex hormones (exposure) with history of tooth loss (outcome), stratified by sex. RESULTS Among post-menopausal women, higher free testosterone (per 1SD) was associated with a greater prevalence of tooth loss [OR 1.49 (95% CI, 1.08-2.05)], whereas higher sex hormone binding globulin (SHBG) was associated with a lower prevalence of tooth loss [OR 0.74 (0.58-0.94)], after adjustment for cardiometabolic risk factors and reproductive factors. In men, higher free testosterone and lower SHBG were associated with a lower prevalent probability of tooth loss in unadjusted analysis, but these associations lost significance after covariate adjustment. CONCLUSION A higher androgenic sex hormone profile in post-menopausal women (i.e., increased free testosterone, lower SHBG) was associated with an increased prevalence of tooth loss, after adjusting cardiometabolic risk factors. No such association was found in men. These findings suggest that sex hormones may influence or serve as a marker for periodontal health.

Abstract
BACKGROUND To evaluate the efficacy of hormone replacement therapy in relieving oral symptoms in postmenopausal women presenting with genitourinary symptoms along with oral dryness. METHODS A case-control study was conducted after selecting 60 postmenopausal women. Oral dryness status of all the patients was evaluated with the help of questionnaire related to oral dryness. These subjects were divided into case group and control group on the basis of response to questionnaire of oral dryness. Unstimulated saliva samples were obtained and analyzed for estimation of salivary estradiol levels by enzyme linked immune sorbent assay technique. After analyzing the result of salivary estradiol levels, case group was subjected to hormone replacement therapy (HRT). The patients were followed up for their response towards oral dryness as well as salivary estradiol levels after the therapy. RESULTS The mean salivary estradiol level before HRT was significantly more among control group as compared to case group (p value < 0.001). Most of the patients complained of dry mouth (26 out of 30); reduced amount of saliva in the mouth (25 out of 30); dry mouth at night (28 out of 30); dry mouth during the day (25 out of 30) before HRT. These complains were significantly reduced after the therapy. The mean salivary estradiol in the case group levels increased significantly after HRT (p value < 0.001). CONCLUSION The salivary estradiol levels were reduced in post menopausal women with the complain of xerostomia as compared to those without the complain of xerostomia. Further these levels can be recovered with the help of hormone replacement therapy.

Salivary Content Might be Associated With Skeletal Status in Postmenopausal Women: SilesiaOsteoActive Study Results. J Clin Densitom 2021; 24:14-21. [PMID: 32146075 DOI: 10.1016/j.jocd.2020.02.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2019] [Revised: 02/03/2020] [Accepted: 02/04/2020] [Indexed: 10/25/2022]
Abstract
AIM The aim of the study was to investigate whether salivary mineral content may be associated with bone status in women after menopause. MATERIAL AND METHODS The study group consisted of 125 postmenopausal women aged 64.3 ± 6.9 yr, derived from the epidemiological SilesiaOsteoActive Study. All participants underwent hip and spine bone densitometry using dual energy X-ray absorptiometry, dental examination, and saliva content analysis. Data for salivary pH, copper, calcium, phosphorus, and zinc concentrations were evaluated. RESULTS Mean femoral neck bone mineral density (BMD) was 0.739 ± 0.118 g/cm2, total hip BMD 0.891 ± 0.14 g/cm2, and spine BMD 0.868 ± 0.14 g/cm2. Salivary pH was significantly lower in women with spinal osteoporosis defined as T-score below -2.5, compared to individuals with normal BMD (pH: 6.65 ± 0.67 vs 6.96 ± 0.58, p < 0.05). There was a significant though weak inverse correlation between Ca concentration in saliva and femoral neck BMD (r = -0.23, p < 0.05). CONCLUSIONS High salivary calcium content and low salivary pH may be indicative of low hip and decreased spine BMD, respectively. These associations may reflect demineralization process (calcium redistribution) influencing bone, and a negative effect of acidity on mineral tissues, although causal pathway remains not clear.

Abstract
Postmenopause is a phase of life which leads physical and emotional instability from multiple health related issues. Oral health in this stage of life is also compromised. Oral health has an impact on general wellbeing of the individual as oral cavity is commonly act as a mirror to general health. Menopause is phase in a woman’s life when menstrual cycles cease by reduced secretion of the ovarian hormones, such as estrogen and progesterone. This review article has emphasized on the diverse oral presentations of peri- and postmenopausal phase of women’s life. Practicing dental surgeons and general physician should be aware of the possible association of postmenopause and its various oral signs and symptoms in this midlife phase of women. It also focuses on its symptomatic management of various oral health issues. This article explains diverse oral conditions in detailed and their management. Stress causing anxiety and depression among this midlife phase of women can lead to alteration in immunity which can again lead to various oral conditions, like lichen planus, apthous ulcer that can cause burning sensation in oral mucosa and alter the food habit. By dealing with all this diverse condition, practicing oral physician can help to reduce and manage oral manifestation of postmenopausal phase of life.

Selected Physicochemical Properties of Saliva in Menopausal Women-A Pilot Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17072604. [PMID: 32290275 PMCID: PMC7177701 DOI: 10.3390/ijerph17072604] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Revised: 04/06/2020] [Accepted: 04/09/2020] [Indexed: 12/24/2022]
Abstract
The aim of this study was to estimate differences in selected physicochemical properties of saliva between menopausal and premenopausal women. Methods: The study population consisted of 9 menopausal women and 15 women of the control group. Laboratory tests included the determination of pH saliva, salivary flow rate, and concentrations of lactoferrin, lysozyme, immunoglobulin A, and ionized calcium. Results: Among menopausal women, statistically significant differences were observed in values of salivary flow rate and lysozyme and ionized calcium concentrations; however, no statistically significant differences for pH and concentrations of lactoferrin and immunoglobulin A were found. The salivary flow rate in the study group was significantly lower compared to that in premenopausal women. In relation to lysozyme, statistically significant differences were found between control group and menopausal women to the disadvantage of the latter. However, the concentration of ionized calcium in the saliva of menopausal women was distinctly higher than in the saliva of the control group. Conclusion: The saliva of menopausal women appeared significantly different from that of the control group. Differences in physicochemical parameters such as salivary flow rate and lysozyme and ionized calcium concentrations were observed. These differences in saliva properties observed in menopause can potentially affect the oral environment of women in this particular period, possibly increasing the risk of some pathological changes in the oral cavity and consequently indicating the need to take special care of this group of female patients in order to help them maintain proper oral health. Dentists and gynecologists should be aware of the problems associated with menopause and need to provide these women complete health care, including dental care as an integral part.

Kubehl K, Temple DH. Reproductive life histories influence cariogenesis: Exploring sex-specific variation in dental caries and survivorship in the human past. AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY 2020; 172:376-385. [PMID: 32112570 DOI: 10.1002/ajpa.24034] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Revised: 01/13/2020] [Accepted: 02/19/2020] [Indexed: 12/12/2022]
Abstract
OBJECTIVES Differences in dental caries prevalence between males and females is considered a reflection of diet. However, recent syntheses argue that sex-specific variation in dental caries prevalence also reflects changes in the oral cavity attributable to variation in reproductive life histories. This study explores sex-specific variation in carious lesions using a life history perspective to understand if differences in reproductive ecology influence this process. MATERIALS AND METHODS Survival probability between 860 males and females from the Terry Collection was compared using carious lesion manifestation (absent, crown presence, root/cemento-enamel junction [CEJ] presence) and sex as covariates and age as a time series variable. A four-way multivariate analysis of variance (MANOVA) comparing carious lesion type by sex, age, and periodontal disease presence was used to evaluate interaction between these variables. RESULTS Individuals with carious lesions have greater survivorship than those without lesions. Males and females with crown lesions do not differ in survivorship from individuals without carious lesions. Females with root/CEJ lesions are characterized by the highest survivorship. A significant interaction was found for root/CEJ carious lesions by age, sex, and periodontal disease presence. Root/CEJ lesion formation in older males was not dependent upon periodontal disease presence, though dependence between these variables characterizes postmenopausal females. CONCLUSION Sex-specific variation in crown lesions is not associated with reproductive life histories and likely reflects diet. By contrast, root/CEJ lesions form through pathways attributable to reproductive life histories, particularly age-induced periodontal disease in females. These results suggest the formation of carious lesions is complex, and in some cases, rooted in reproductive life histories.

Abstract
Background Women's health undergoes physiological, pathological and psychological changes after menopause. Reduced estrogen levels have been implicated in the pathogenesis of osteoporosis in postmenopausal women. Estrogen is also known to affect the salivary gland functions. To understand the association between serum estrogen, osteoporosis and salivary calcium, the present cross-sectional study was undertaken. Aim The aim of this study is to determine salivary calcium levels and its use for the diagnosis of osteoporosis in postmenopausal women. Methodology Ninety individuals divided into three groups of healthy controls, pregnant women and postmenopausal women were selected. Serum estrogen, salivary calcium and bone mineral density (BMD) at the heel region were estimated. Statistical analysis using the Mann-Whitney U-test was done to compare the results within the groups. Results Mean estrogen levels were 115.8 ± 80.18 pg/mmol in control group, 7729.4 ± 907.6 pg/mmol in pregnant group and 51.2 ± 74.51 pg/mmol in postmenopausal group, respectively. The mean salivary calcium in control, pregnant and postmenopausal groups was 3.12 ± 0.63, 3.19 ± 0.62 and 7.12 ± 0.79 μg/dl, respectively. Paired comparison within the groups showed high statistical significance (P = 0.0000) in the salivary calcium levels. The mean BMD of -2.3 (standard deviation [SD] ± 0.83) in the postmenopausal group was significantly lower than -0.6 (SD ± 0.99) and -0.2 (SD ± 1.42) of pregnant and control groups, respectively. Conclusion A negative correlation was found between estrogen and bone density. A significant difference in salivary calcium was noted in the study groups, highlighting the role of salivary calcium in the detection of early bone changes in postmenopausal women.

Abstract
OBJECTIVES Calcium is an inorganic component of the saliva, which is especially important in oral and dental health. This study sought to compare unstimulated salivary calcium level of dentulous and edentulous patients. MATERIALS AND METHODS This case-control study was conducted on 72 participants, including 36 dentulous and 36 edentulous patients. The unstimulated salivary flow rate of patients and the mean salivary calcium concentration were measured and compared. The data were analyzed using the nonparametric Mann-Whitney U-test. RESULTS The mean age of participants was 56.3 years. The mean number of teeth was 18.9 in the dentulous group. No significant difference was noted in salivary calcium level of dentulous and edentulous patients. The mean salivary calcium concentration was 0.61 ± 0.3875 mmol/L in dentulous and 0.8025 ± 0.5975 mmol/L in edentulous patients. Salivary calcium level had a significant inverse correlation with salivary flow rate (r = -0.370, p = 0.027), and by every 1-unit increase in salivary flow rate, salivary level of calcium significantly decreased by 3.85 units. CONCLUSION Edentate had averagely higher salivary calcium level compared to dentulous. The salivary concentration of calcium ion is not correlated to the presence or absence of teeth. Salivary flow rate reduces the calcium concentration.

Abstract
Different phases of a woman's life: Puberty, menses, pregnancy, and menopause have varied influence on her oral health. During the menopause, women go through biological and endocrine changes, particularly in their sex steroid hormone production, affecting their health. Because the oral mucosa contains estrogen receptors, variations in hormone levels directly affect the oral cavity. A few oral conditions and or diseases are seen more frequently during post menopausal years. Role of hormones affecting the health of oro-dental tissues, as well as treatment by HRT in ameliorating these conditions is not clear. There is paucity of randomized controlled trials in this field and more data is needed, before the recommendations for oral health care in post menopausal women can be made. A gynecologist sitting in menopausal clinic should be aware of oral changes happening during this period, and dental needs of these women and should refer them to the dental specialists accordingly. On the other hand, a dentist should also be sensitized about the menopausal status of the woman, her HRT status and special preventive and treatment needs.

Abstract
OBJECTIVE The primary objective of this study was to estimate and secondary objective was to compare the serum calcium levels and serum parathyroid hormone (PTH) levels in post-menopausal women with and without oral dryness (OD). MATERIALS AND METHODS A case-control study was carried out on 80 selected post-menopausal women. Salivary flow was assessed by flow rate; serum calcium concentrations were assessed through Semi Autoanalyzer by Arsenazo III reaction. The serum PTH concentration was measured by the enzyme-linked immunosorbent assay. Severity of OD was assessed by a questionnaire through which the xerostomia inventory (XI) score could be measured. Statistical analysis of Student's t-test, Mann-Whitney test and Pearson's correlation was used. RESULTS There was a significant difference in mean values of both serum PTH concentration and XI score in post-menopausal women with/without OD (p < 0.001). No statistically significant difference (p = 0.354) was found in salivary flow rate and serum calcium levels in post-menopausal women in both groups. A positive correlation was found between the serum PTH and XI score in both case and control groups (p < 0.05). CONCLUSION Severity of oral dryness in post-menopausal women is associated with the high levels of serum PTH. However, the correlation of severity of OD with serum calcium could not be established.

Abstract
BACKGROUND Climateric is considered to be a natural phase of life which by definition is the period of life starting from decline in ovarian activity until after the end of ovarian function. It is accompanied by various health consequences that include the changes in saliva too. This study was carried out to evaluate the salivary flow rate, pH, buffering capacity in pre-menopausal, post-menopausal and post-menopausal women on HRT. AIMS AND OBJECTIVES (1) To evaluate the salivary flow rate, pH of resting saliva and stimulated saliva and buffer capacity of stimulated saliva in pre-menopausal, post-menopausal and post-menopausal women on Hormone Replacement Therapy (HRT). (2) To compare the above salivary findings between pre-menopausal, post-menopausal and post-menopausal women on HRT. MATERIALS AND METHODS The study was carried out on 60 patients. These patients were divided into three groups of 20 patients: Group 1: Pre-menopausal women (control), Group 2: post-menopausal women (case), Group 3: post-menopausal women on HRT (case). The control group consisted of 20 women volunteers, having regular ovulatory menstrual cycles with no known systemic illness and deleterious habits and Group 2 consists of 20 post-menopausal women and Group 3 will consist of 20 post-menopausal women on HRT. After clearing the mouth by swallowing, stimulated saliva was collected after chewing paraffin for 10 mins in to a glass centrifuge tube graded in 0.1 mL increments up to 10mL.in rare cases the collection time will be reduced or extended (5-15 min), salivary flow rate will be determined as ml/min, immediately after collection, pH was determined by dipping pH test paper directly into the sample of oral fluid, salivary buffer capacity was determined by using saliva check buffer kit (GC corporation). The data obtained was statistically evaluated using chi-square test, fisher exact test ANOVA analysis. RESULTS In our study we found salivary flow rate significantly lower in the post-menopausal women in comparison with the menstruating women and also there was improvement in the flow rate in individuals who were on HRT, it was also observed that salivary pH of the post-menopausal group was significantly lower than that of the control group, statistically significant difference in buffer capacity values was found between the groups however buffer capacity values were higher in the post-menopausal group than the control group. CONCLUSION From the above study it is clear that post-menopausal women will present with oral discomfort, while HRT can improve the same. Hence our role as physicians and health care providers is to incorporate preventive dental health care in post-menopausal women and clearly inform patients about both the benefits and the limitations of HRT.

One of the most common oral manifestations of menopause is xerostomia. Oral dryness can profoundly affect quality of life and interfere with basic daily functions, such as chewing, deglutition, and speaking. Although the feeling of oral dryness can be ameliorated after estrogen supplementation, the side effects of estrogen greatly restrict its application. We previously found that N-myc downstream-regulated gene 2 (NDRG2) is involved in estrogen-mediated ion and fluid transport in a cell-based model. In the present study, we used an ovariectomized rat model to mimic xerostomia in menopausal women and constructed two adenovirus vectors bearing NDRG2 to validate their therapeutic potential. Ovariectomized rats exhibited severe sialaden hypofunction, including decreased saliva secretion and ion reabsorption as well as increased water intake. Immunohistochemistry revealed that the expression of NDRG2 and Na(+) reabsorption-related Na(+)/K(+)-ATPase and epithelial sodium channels (EnaC) decreased in ovariectomized rat salivary glands. We further showed that the localized delivery of NDRG2 improved the dysfunction of Na(+) and Cl(-) reabsorption. In addition, the saliva flow rate and water drinking recovered to normal. This study elucidates the mechanism of estrogen deficiency-mediated xerostomia or sialaden hypofunction and provides a promising strategy for therapeutic intervention.

Abstract
AIM Measurements of salivary calcium level may be a useful screening tool for osteoporosis in postmenopausal women. The purpose of this study was to clarify whether this measure is valid compared with dual-energy X-ray (Bone Mineral Density) screening tools in osteoporosis. METHODS A case-control study was carried out in 40 postmenopausal women with osteoporosis (T-score ≤ -2.5) and 40 women without osteoporosis (T-score > -1 bone mineral density). Salivary samples were collected and calcium concentrations were measured and expressed as mg/dL. Receiver operating characteristic curve analyses was used to determine the optimal cut-off thresholds for salivary calcium in healthy postmenopausal women. RESULTS The cut-off point for salivary calcium was 6.1 mg/dL. The sensitivity and specificity, respectively, for identifying women with osteoporosis, were 67.5 (95%CI 52.33-82.67) and 60% (95%CI 44.62-75.38). The area under curve (AUC) was 0.678 (95%CI 0.56-0.79), the positive predictive value (PPV) was 62.79 (95%CI 47.74-77.84) and negative predictive value (NPV) was 64.86% (95%CI 49.27-80.46). The positive likelihood ratio was 1.688 and the negative likelihood ratio was 0.542. CONCLUSIONS Salivary calcium concentration discriminates between women with and without osteoporosis and constitutes a useful tool for screening for osteoporosis.

Abstract
OBJECTIVE The aim of this study was to verify the association between salivary calcium and serum oestrogen levels with oral dryness in post-menopausal women. Also, the correlation between these variables was evaluated. METHODS A case-control study was carried out on 60 selected menopausal women with and without oral dryness feeling (30 as case and 30 as control) conducted in the Department of Oral Medicine and Radiology, Maharishi Markandeshar University, Mullana, India. Paraffin-stimulated saliva samples were obtained by expectoration. Salivary calcium concentrations were assessed colorimetrically using Arsenazo III reaction. The serum oestrogen concentration was measured using ELISA. Statistical analysis of Student's t-test and Pearson correlation was used. RESULTS There was significant difference in mean values of both salivary calcium concentration and serum oestrogen between case and control groups. The result obtained also showed that an inverse correlation was found between salivary calcium concentration and serum oestrogen levels in both the groups and in total sample size. CONCLUSION Oral dryness in post-menopausal women is associated with high levels of salivary calcium and low levels of serum oestrogen. The concentrations of salivary calcium and serum oestrogen are inversely correlated in post-menopausal women, regardless of the presence or absence of oral dryness.

Abstract
This study aims to investigate salivary flow and biochemical constituents of menopausal-age women with the hypothesis that women using hormone therapy (HT) might present better saliva values than non-users. Two hundred HT users and 200 non-users were selected at random from a cohort study of 3,173 peri- and postmenopausal women and invited to a 2-year clinical follow-up study. Clinical examination with saliva sampling was made at baseline and 2 years later. Salivary total protein, albumin, and immunoglobulin (Ig) concentrations were analyzed. Final material included 106 consistent HT users and 55 non-users. Backward logistic regression analysis was made to determine the risk factors for higher or lower than medium salivary protein values. No difference was seen in salivary flow rate, total protein, and IgA values between baseline and follow-up measurements or between the groups. Albumin, IgG, and IgM concentrations were significantly lower in the 2-year samples of the HT group when compared with baseline. IgA and IgM values were higher in the non-HT 2-year samples when compared with the corresponding HT samples. The only significant explanatory factor for higher than median salivary albumin concentration was the number of teeth both at baseline and 2 years later. HT possibly improved epithelial integrity since the concentrations of serum components albumin, IgG, and IgM decreased during the follow-up. HT as such does not seem to affect saliva, although it may modify it. The clinical relevance of these results needs to be assessed in future studies.

Abstract
Usually no distinction is made between female and male salivary glands although cyclic changes of and ⁄ or differences in serum and salivary sex steroid concentrations characterize women and men. Moreover, sexual dimorphism is well recognized in salivary glands of rodents.Salivary glands contain estrogen and androgen receptors and are, according to modern high throughput technologies,subjected to gender differences not explainable by gene dose effects by the X chromosome alone. Because sex steroids are lipophilic, it is often thought that approximately 10% of them passively diffuse from plasma to saliva. Indeed, saliva can find use as sample material in sports medicine, pediatrics, veterinary medicine and behavioral sciences. Last but not least, humans and other primates are unique in that they have a reticular zone in their adrenal cortex, which produces dehydroepiandrosterone and androstendione pro-hormones. These are processed in peripheral tissues, not only in female breast and uterus and male prostate, but also in salivary glands by an intracrine enzymatic machinery to active 17b-estradiol,dihydrotestosterone and others, to satisfy and buffer against a constantly changing needs caused by circadian,menstrual, pregnancy and chronobiological hormonal changes in the systemic circulation. Female dominance of Sjögren's syndrome and certain forms of salivary gland cancer probably reflect these gender-based differences.

Abstract
OBJECTIVE The aim of this study was to evaluate the correlation of severity of oral dryness (OD) with serum and saliva parathyroid hormone (PTH) and calcium levels, and to compare serum and stimulated whole saliva PTH and calcium between menopausal women with/without OD. METHODS A case-control study was carried out in 76 (38 as case and 38 as control) selected menopausal women with/without OD conducted at the Clinic of Oral Medicine, Tehran University of Medical Sciences (TUMS). Xerostomia Inventory (XI) score was also used as an index of OD severity. Serum and saliva Ca(+2) concentrations were assessed colorimetrically by Arsenazo reaction. PTH concentration was analyzed by enzyme-linked immunosorbent assay (ELISA). Statistical analysis of Student t test and Spearman correlation was used. RESULTS The mean saliva calcium and PTH concentrations and outputs, and serum PTH were significantly higher in the case group, compared with control. However, there were no significant differences in serum calcium concentration and stimulated saliva flow rate between groups. XI score correlated significantly with serum PTH (r = 0.387, P = .004), saliva concentration (r = 0.382, P = .002) and output (r = 0.346, P = .007) of PTH; and also with saliva concentration (r = 0.326, P = .013) and output (r = 0.315, P = .018) of calcium; but not with serum calcium and saliva flow rate. CONCLUSION OD severity correlated positively with serum and stimulated whole saliva PTH, and with saliva calcium levels in this group of menopausal women. Thus, salivary calcium and PTH levels appear associated with OD and menopause.

Abstract
OBJECTIVES To review the literature about oral symptoms and signs at the menopause with an emphasis on hormone replacement therapy (HRT). To give practical guidelines for women and their physicians in menopause-related oral health problems. METHODS The PubMed and Cochrane databases was searched until mid January 2009 with key words such as "menopause", "menopausal complaints", "postmenopausal complaints" and "oral diseases", "oral discomfort", "dental health", "dental diseases", "saliva", "burning mouth syndrome", "dry mouth", "xerostomia". Because of a scarcity of controlled studies no systematic review could be conducted. RESULTS Oral discomfort is found in many menopausal women in addition to more general climacteric complaints. The principal peri- and postmenopausal symptoms are dry mouth and burning mouth (glossodynia) which, in turn, may increase the occurrence of oral mucosal and dental diseases, such as candidiasis. The mechanisms of hormone-related oral symptoms and signs are not known although oestrogen receptors, for example, have been detected in the oral mucosa and salivary glands. In principle, the histology of oral and vaginal mucosa is very similar and thus their symptoms might share a common cause. Yet, hormone replacement therapy use does not necessarily prevent or help women with oral symptoms. CONCLUSION Properly controlled long-term randomized studies are needed to assess the effect of HRT on oral discomfort. Future gene profiling could identify women who may or may not benefit from HRT with regard to oral symptoms.

Abstract
OBJECTIVES Long-term calcium intake is related to the formation of urinary stones. Structure and composition of kidney and gallstones are similar to dental calculus. Saliva is the source of calcium for supragingival dental calculus formation. The aim of this preliminary study was to evaluate the possible effects of long-term calcium and vitamin D supplementation with or without alendronate administration on salivary electrolyte concentrations and supragingival calculus formation in osteoporotic women. METHODS Thirty-one female patients with osteoporosis for at least 3 years participated in this study. Eighteen women were taking calcium plus vitamin D plus alendronate, while 13 women were taking only calcium plus vitamin D supplements. Eleven systemically healthy women volunteered for the control group. Whole saliva samples were collected from all women before initiation of any periodontal intervention. Plaque index, probing depth, clinical attachment level, bleeding on probing, and calculus index were recorded at six sites/tooth. Salivary concentrations of ionic calcium, potassium, magnesium and sodium were determined by atomic absorption spectrophotometer. Results were evaluated statistically by non-parametric tests. RESULTS No significant differences were found in clinical parameters or results of saliva analysis between the study groups (p > 0.05). CONCLUSION Within the limits of this preliminary study, it is suggested that long-term calcium and vitamin D supplementation with or without alendronate does not appear to have a significant effect on supragingival calculus formation or saliva total calcium, potassium, magnesium and sodium concentrations. Larger-scale studies investigating the possible effects of various treatment modalities of osteoporosis on supragingival calculus formation are required to better clarify this issue.

Abstract
As relatively little is known about the effect of age on salivary electrolytes we studied the composition of saliva as function of age to provide reference values for healthy non-smoking women. All non-medicated and non-smoking 30-59-year-old subjects (n=255) selected from among 1030 women participating in a screening program formed the material of the present study. Salivary calcium, inorganic phosphate, magnesium, sodium, potassium, protein and flow-rate of stimulated whole saliva were measured. We found age-related changes in salivary calcium and phosphate concentrations (p=0.001 and p=0.004, respectively, one-way ANOVA). Peak values occurred at around 50-54 years of age. Age had no effect on flow-rate, magnesium, sodium, potassium or proteins. The concentration of sodium correlated positively, while phosphate, potassium, magnesium and protein correlated negatively with the salivary flow-rate. Calcium was the only electrolyte which had no association with flow-rate. Our study provides reference values for salivary electrolytes of 30-59-year-old women.

Abstract
The aim of this study was to compare stimulated whole saliva flow rate and composition of menopausal women with/without oral dryness (OD) feeling. A case-control study was carried out in 42 selected menopausal women aged 52-73 years with or without OD feeling (21 as case and 21 as control) conducted at the Clinic of Oral Medicine, Tehran University of Medical Sciences. Paraffin-stimulated saliva samples were obtained by expectoration. The stimulated whole saliva composition was measured by a spectrophotometer [magnesium (Mg(+2)), calcium (Ca(+2)), chloride (Cl(-)), inorganic phosphate (Pi) and total protein], flame-photometry [sodium (Na(+))] and ion selective electrode (ISE) [potassium (K(+))] methods. No significant differences were found in stimulated whole saliva flow rate, Mg(+2), Cl(-), Pi, Na(+), K(+) and total protein concentrations between the two groups, but the mean calcium concentration was significantly higher in cases than in controls (P = 0.003). It seems that the level of salivary calcium concentration may be higher in menopausal women with OD feeling than in the control group.

Abstract
When dental caries rates are reported by sex, females are typically found to exhibit higher prevalence rates than males. This finding is generally true for diverse cultures with different subsistence systems and for a wide range of chronological periods. Exceptions exist, but are not common. In this paper, we present new data for sex differences in dental caries rates among the Guanches (Tenerife, Canary Islands), summarize results of meta-analyses of dental caries prevalence, and emphasize new research that stresses the critical role of female hormones and life-history events in the etiology of dental caries. Among the Guanches, corrected tooth-count caries rates for females (8.8%, 158/1,790) are approximately twice the frequency of caries among males (4.5%, 68/1,498). Higher caries prevalence among females is often explained by one of three factors: 1) earlier eruption of teeth in girls, hence longer exposure of girls' teeth to the cariogenic oral environment, 2) easier access to food supplies by women and frequent snacking during food preparation, and 3) pregnancy. Anthropologists tend to favor explanations involving behavior, including sexual division of labor and women's domestic role in food production. By contrast, the causal pathways through which pregnancy contributes to poorer oral health and higher caries rates are deemphasized or discounted. This paper presents recent research on physiological changes associated with fluctuating hormone levels during individual life histories, and the impact these changes have on the oral health of women. The biochemical composition of saliva and overall saliva flow rate are modified in several important ways by hormonal fluctuations during events such as puberty, menstruation, and pregnancy, making the oral environment significantly more cariogenic for women than for men. These results suggest that hormonal fluctuations can have a dramatic effect on the oral health of women, and constitute an important causal factor in explaining sex differences in caries rates.

Abstract
OBJECTIVE Our recent studies suggest, that elevated calcium concentration of saliva is characteristic of periodontitis. In this study we analyzed the effect of smoking on salivary calcium and bone density by comparing the level of salivary calcium and the ultrasound scale of bone density of heavy smokers to those of non-smokers. DESIGN Salivary samples were collected from 603 women (50-62 years) participating in a pre-screen referral program for osteoporosis. Out of this group a total of 577 were accepted for the present study. General health, medications and tobacco smoking were recorded. The group included 487 non-smokers, 37 moderate smokers (1-10 cigarettes per day) and 53 heavy smokers (>10 cigarettes per day). Bone density was measured at the right heel by the quantitative ultrasound technique. Calcium and phosphate concentrations of saliva were measured and expressed as microg/ml of saliva. RESULTS The ultrasonographic variables of the heel, broadband ultrasound attenuation (BUA), speed of sound (SOS) and T-score (a standard deviation unit from mean values of healthy young adults) of heavy smokers were significantly lower than those of women who did not smoke (P = 0.007, 0.014 and 0.011, respectively). Salivary calcium concentration of heavy smokers 70.5 (14.6) microg/ml was higher than that of non-smokers 64.0 (14.1) microg/ml (P = 0.001). There were no significant differences in salivary phosphate level or in the salivary flow rate between heavy smokers and non-smokers. CONCLUSIONS Heavy smokers seem to have lower bone mineral density and higher salivary calcium than their non-smoking counterparts. We suggest that the high salivary calcium concentration of smokers is in connection with skeletal calcium disturbances.

Abstract
Several systemic conditions may have an influence on oral health. Hormone replacement therapy (HRT) has a positive effect on alveolar bone of menopausal women and smoking a negative effect. However, little is known about their effect on saliva. The purpose of this study was to examine the effect of hormone-use and tobacco smoking on the composition of saliva, in particular on the inorganic constituents. Salivary samples were collected from a representative study group comprising 1,013 women (30-59 years) participating in a pre-screen referral program for osteoporosis. The participants were divided into 2 subgroups according to age. The younger group (< or = 45 years) comprised 413 women and the older group (> or = 50 years) 600 women. Salivary calcium, magnesium, sodium, potassium, inorganic phosphate, total protein, and flow rate of paraffin-stimulated saliva were measured. In the older age group, female sex steroid users (hormone users) had lower salivary protein concentrations than non-users. Smoking was associated with high salivary calcium, magnesium, and potassium levels in the group of older participants. Neither tobacco smoking nor female sex steroid hormones had any significant effect on the salivary composition in the younger age group. In conclusion, smoking was reflected more clearly than female sex steroid hormone-use in the inorganic composition of saliva in the older age group. The salivary composition was not affected by hormone-use or by smoking among the younger age group.

Abstract
Physical inactivity is prevalent among patients with intellectual disability. Because little is known about the oral effects of poor mobility, we reviewed the medical and dental charts of institutionalized dentate patients (n = 214; 40.2 years +/- 12.1) of the Special Welfare District of Southwestern Finland. The number of decayed, missing, and filled teeth (DMFT), the number of retained teeth, dental treatment visits, and the type of the first treatment visit were recorded. Physical activity was good in 55% and severely reduced or completely absent in 45% of the patients. The degree of intellectual disability was mild or moderate in 40% and severe or profound in 60% of the patients. The walking patients weighed more (64.3 (19.6) versus 44.4 (14.4) kg; P< 0.001), had fewer secondary diagnoses (1.4 (1.3) versus 2.2 (1.4); P< 0.001), fewer daily medications (4.0 (2.1) versus 4.8 (2.4); P< 0.02), higher DMFT scores (18.5 (8.2) versus 14.8 (9.2); P < 0.05), and more dental treatment visits (2.7 (2.4) versus 2.0 (1.3); P< 0.03) than patients with poor physical activity. Periodontal treatment given as the primary type of dental care was more common among subjects with poor mobility than among those with good motor activity (P < 0.002). Poor physical activity was related to better dental health, higher need for periodontal therapy, and fewer dental visits than in patients with good motor activity.
