Relationship of stimulated whole saliva cortisol level with the severity of a feeling of dry mouth in menopausal women

doi: 10.1111/j.1741‐2358.2010.00403.x Relationship of stimulated whole saliva cortisol level with the severity of a feeling of dry mouth in menopausal women Objectives: To evaluate the relationship of stimulated whole saliva cortisol level with the severity of a feeling of dry mouth (DM) in menopausal women. Background: A feel of DM is a major complaint for many elderly individuals and strongly associated with the menopause. The exact mechanisms that mediate sensation of DM in menopausal women have not been firmly established. Methods: A case–control study was carried out on 104 selected menopausal women with/without a feeling of DM, conducted at the Clinic of Oral Medicine, Tehran University of Medical Sciences. Xerostomia Inventory (XI) score was used as an index of DM severity. Stimulated whole saliva cortisol concentration (stimulated by chewing standard‐sized paraffin for 60 s) was measured by ELISA. Statistical analysis by Student’s t‐test and Spearman correlation was used. Results: The mean cortisol concentration of saliva, but not saliva cortisol output, was significantly higher in the cases than in the controls. There was significant positive correlation between XI score and concentration (r = 0.357, p = 0.000) or output (r = 0.223, p = 0.017) of stimulated whole saliva cortisol. Conclusions: It appears that stimulated whole saliva cortisol is high in menopausal women with a feeling of DM.

doi: 10.1111/j.1741‐2358.2011.00580.x
Correlation of serum oestrogen with salivary calcium in post‐menopausal women with and without oral dryness feeling 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.     

Salivary tests associated with elderly people’s oral health

doi: 10.1111/j.1741‐2358.2012.00627.x Salivary tests associated with elderly people’s oral health Introduction: The saliva constitutes essential condition for the individual’s health. Aim: Identify the relation of the salivary flow and saliva pH with medicine use and oral discomfort in elderly. Methods and materials: Cross‐sectional study with 68 elderly living in a long staying institution. Salivary tests were performed based on Bo Krasse’s methodology. For pH, the Universalindikator – Merck tape was used. A questionnaire was applied, organising data through Software SPSS version 17. Pearson’s qui‐square distribution, Fisher’s exact test and t‐test for paired data were used, with significance level of 5% and confidence interval of 95%. Results: Among the 68 elderly (average of 70.4 years, SD ± 7.27), 80% showed normal pH. The rate of salivary flow was as follows: very low, 32.3%; lowered, 41.2%; and normal, 25.5%; 30.9% reported dry mouth; 22.1% problems with taste; 17.6%, dysphagia; and 14.7%, burning mouth. 76.5% used medicines. There was statistical significance between medicine use and dry mouth (p = 0.015). They showed an association between salivary flow and medicine use (p = 0.048), feels dry mouth (0.018) and difficulty to swallow (p = 0.046), and saliva pH without stimulation and feels dry mouth (p = 0.003), difficulty to swallow (p = 0.006) and burning mouth sensation (p = 0.014). Conclusion: Low salivary flow and saliva pH interfere on elderly people’s health and medicine use influences on results.     

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

doi: 10.1111/j.1741‐2358.2011.00608.x 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.     

25‐OH‐D3, calcium,phosphorus, and alkaline phosphatase content in sera from captive polar bear (Ursus maritimus) cubs at the Denver Zoological Foundation

After the development of rickets in two hand‐reared polar bear (Ursus maritimus) cubs at the Denver Zoological Foundation we initiated a project opportunistically evaluating sera 25‐OH‐D₃, calcium, phosphorus, and alkaline phosphatase levels in seven mother‐reared polar bear cubs. From one to three serum samples were obtained while the cub was still in the den with no access to natural sunlight and one after the cub exited the den. The sera 25‐OH‐D₃ increased as the cubs grew (108±37 nmol/L [n=7] while in den, 184.6±48.3 nmol/L [n=7] out of the den) but were substantially lower then captive adults (348±215 nmol/L [n=36]) or free‐ranging adults (360±135 nmol/L [n=56]). We found that age was correlated significantly with 25‐OH‐D₃ levels but den status (in or out) was not significant. Sera calcium and phosphorus values were highest in denned cubs (calcium, 2.9±0.4 mmol/L [n=13]; phosphorus, 3.1±0.5 mmol/L [n=13]) and then declined as the cubs matured and left the den (calcium, 2.5±0.1 mmol/L [n=7]; phosphorus, 2.4±0.4 mmol/L [n=7]). The enzyme alkaline phosphatase (presumably the bone isoenzyme) was high in denned growing cubs (831±426 IU/L [n=13]) and then declined gradually as the cubs aged and exited the den (96±83 IU/L [n=7]).

Enhancing the quality of life in elderly women through a programme to improve the condition of salivary hypofunction

doi: 10.1111/j.1741‐2358.2011.00594.x Enhancing the quality of life in elderly women through a programme to improve the condition of salivary hypofunction Objective: The purposes of this study were to examine the effects of oral exercise intended to improve the function of the oral cavity in the elderly and their quality of life to pave the way for the development of oral‐health promotion programmes geared towards the elderly. Methods: The subjects were 78 female Koreans who resided in Seoul and were aged 65 years and older. During a 3‐month period, an oral function promotion programme was conducted twice a week, between 10.00 am and 12.00 pm , applying oral exercise suggested by a Japanese public health centre. A survey was conducted by interviewing the selected women to determine the state of their subjective dry mouth, quality of life related to oral health and jaw functional limitation. Their opening, unstimulated whole saliva and pronunciation speed were measured before and after the oral function exercise programme. Results: The subjects showed a significant improvement in subjective dry mouth symptoms, relevant behaviour, the level of discomfort caused by dry mouth and subjective jaw functional limitation during mastication and swallowing and emotional expression after receiving the oral exercise. After the oral exercise, there was a significant increase in mouth opening, unstimulated whole saliva and speaking speed (‘patakala’ pronunciation) after oral exercise. There was also significant progress in their quality of life related to oral health. Overall improvement in subjective dry mouth symptoms and relevant behaviour over time after oral exercise had a positive correlation with the level of improvement in discomfort triggered by dry mouth and mastication. The level of improvement in OHIP‐14 had a positive correlation with the level of overall improvement in dry mouth symptoms and behaviour, the level of improvement in discomfort by dry mouth and that in mastication and swallowing. Conclusion: This study showed the effects of the oral function promotion programme and correlation of oral condition and oral health‐related quality of life. It is suggested that this oral function promotion programme has positive effects on both objective and subjective oral conditions. It is strongly recommended that this programme, along with other oral health promotion programmes, be implemented to improve oral function and oral health‐related quality of life for the elderly.     

Self-reported dry mouth in Swedish population samples aged 50, 65 and 75 years

doi: 10.1111/j.1741‐2358.2010.00420.x Self‐reported dry mouth in Swedish population samples aged 50, 65 and 75 years Background: Reduced salivary flow may have a negative impact on general well‐being, quality of life and oral health. Objectives: To examine xerostomia in 50‐, 65‐ and 75‐year‐olds, background factors and effect on Oral Impacts on Daily Performances (OIDP). Methods: In 1992, a questionnaire was sent to all 50‐year‐old persons (n = 8888) in two Swedish counties. In 2007, the same questionnaire was sent to all 65‐year‐olds (n = 8313) in the two counties and to all 75‐year‐olds (n = 5195). Response rate was for the 50, 65 and 75 year olds 71.4, 73.1 and 71.9%, respectively. Results: Xerostomia was higher in women than in men in all age groups. There was higher prevalence of xerostomia with increasing age in both sexes and it was more frequent at night than during daytime. ‘Often mouth dryness’ was 2.6–3.4 times more prevalent in those who reported an impact from OIDP. The highest odd ratios were for daytime xerostomia and for the variables burning mouth (17.1), not feeling healthy (4.5), daily smoking (4.4), and medication (4.1). Conclusions: The dramatic increase of xerostomia between age 50 and 75, especially amongst women, needs to be considered in the management of this age group.     

Metabolic balance studies in patients with Paget's disease receiving salmon calcitonin over long periods.

Metabolic balance and calcium kinetic studies were performed in four patients with Paget''s disease before treatment with salmon calcitonin and during the early and late stages of the treatment, which lasted 9 to 19 months, A significant decrease in bone turnover and 24-hour urine hydroxyproline and serum alkaline phosphatase values was observed in all patients. In contrast, the calcium, phosphorus and magnesium balances did not change significantly. In agreement with this, the partial body calcium, measured by in vivo neutron activation analysis, did not change. Intestinal calcium absorption increased initially, but returned to baseline levels 9 to 19 months after the study began. During the initial period there was a small, significant, but transient decrease in tubular reabsorption of phosphorus; this was accompanied by a significant decrease in serum phosphorus values--probably a direct effect of calcitonin rather than evidence of secondary hyperparathyroidism. Administration of salmon calcitonin to patients with Paget''s disease decreases bone turnover without affecting calcium and phosphorus balances.     

Maternal Factors in Neonatal Hypocalcaemia: A Study in Three Ethnic Groups

To assess the significance of various maternal and neonatal factors in the aetiology of neonatal tetany we have investigated the serum calcium, phosphorus, magnesium, and heat-labile alkaline phosphatase of 250 mothers from three ethnic groups at several stages of pregnancy and the serum calcium, phosphorus, and magnesium of many of their infants. Subclinical hypocalcaemia was found to be much commoner in full-term infants on the sixth day of life than is generally appreciated, especially during the winter months and in babies of Asian parents. It is considered that this is a result of high phosphorus loads in artificial milks and is also influenced by maternal vitamin D and possibly calcium intake during pregnancy. The importance of ensuring that Asian women take adequate vitamin D supplements during pregnancy is stressed.     

Bone mineralization by OST-6 (OsteoCare), a herbomineral preparation, in experimentally induced rickets in rats.

In the present study the efficacy of OST-6 (OsteoCare), a herbomineral preparation, on bone mineralization in experimental rickets has been evaluated. This was accomplished by feeding pregnant rats and subsequently their pups with vitamin D and calcium deficient (VDCD) with low phosphorus diet. The parameters such as serum and bone mineral contents (calcium and inorganic phosphorus), serum alkaline phosphatase, sex hormones and histology of bone were considered. VDCD resulted in a significant reduction in bone and serum calcium and inorganic phosphorus, increased serum alkaline phosphatase and decreased sex hormones (testosterone in males, progesterone and oestrogen in females). Histologically the bone showed osteodystrophic changes and disproportionate cartilaginous proliferations in the epiphyseal region. Incorporation of OST-6 into feed at 5% concentration resulted in a complete reversal of rickets, which was substantiated by biochemical and histological observations. It has been concluded that OST-6 is useful in the management of rickets in a natural way through herbal resources.     

Fluorometric measurement of alkaline phosphatase activity in algae

SUMMARY. Using both cultures of algae and natural populations, alkaline phosphatase activity located on the cell surface has been measured by a fluorometric procedure. This was done in order to establish optimum standard conditions for the measurement of this activity as an indicator of phosphorus deficiency and to provide a means of interpreting alkaline phosphatase measurements on natural phytoplankton populations. A concentration of 10 μM o-methylfluorescein phosphate saturates or nearly saturates the reaction in a variety of situations. In most trials, rates increased with temperature to or beyond 35°C. Optimum pH values in the range 7–10 were observed. In six of the algae examined, maximum alkaline phosphatase activities were dependent on external calcium at 100 μM or more. One alga, Synura uvella , showed acid phosphatase activity, peaking at pH 5–6, induced by phosphorus deficiency. Based on comparisons between P-sufficient and P-deficient cultures, alkaline phosphatase activities in excess of 0.1 μmol o-methylfluorescein phosphate hydrolysed per mg dry weight per h or 0.1 μmol per μg ATP per h are suggested as indicative of phosphorus deficiency.     

Biochemical Response of Late Rickets and Osteomalacia to a Chupatty-free Diet

Eight Pakistani children with late rickets and two Pakistani women with osteomalacia were given a chupatty-free diet for seven weeks, substituting leavened bread of lower extraction. On this diet serum calcium levels rose to normal or near normal, levels of serum inorganic phosphorus rose slightly but significantly, and serum alkaline phosphatase levels showed a definite rise indicative of healing bone disease. It is concluded that the high phytate content of unleavened bread is the major cause of late rickets and osteomalacia in Pakistani and Indian communities in the United Kingdom. The simplest prophylactic measure seems to be the additional fortification with calcium carbonate of the high extraction flour used in preparing unleavened bread.     

Hematology and serum chemistry in the white-crowned mangabey (Cercocebus torquatus lunulatus) and in the mandrill (Mandrillus sphinx)

Abstract: Reference values of some hematologic and plasma chemical parameters were established in two species of clinically normal Cercopithecidae. The following variables were studied in seven mandrills (Mandrillus sphinx) and nine white-crowned mangabeys (Cercocebus torquatus lunulatus): hematocrit, hemoglobin concentration, erythrocyte and leucocyte counts, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, glucose, urea, uric acid, cholesterol, creatinine, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, creatinine phosphokinase, lactic dehydrogenase, gamma glutamyl transpeptidase, total serum proteins, albumin, globulins, albumin-globulin ratio, sodium, potassium, calcium, magnesium, total phosphorus, chloride, and serum osmolality. Few differences were observed when compared with human hematological data and with other species of Cercopithecidae Primates.     

Medication in elderly people: its influence on salivary pattern,signs and symptoms of dry mouth

doi:10.1111/j.1741‐2358.2009.00293.x
Medication in elderly people: its influence on salivary pattern, signs and symptoms of dry mouth Objective: To compare stimulated and non‐stimulated salivary flow, pH, buffering capacity and presence of signs and symptoms of hyposialie and xerostomia in elderly patients, with senile dementia using medication and healthy elderly subjects not using medication. Methods: Forty individuals (mean age: 68.5 years) were divided into two groups, according to the use (G1) or non‐use (G2) of medication and the presence (G1) or absence (G2) of senile dementia. Data with reference to the general health condition, use of medication and the patient’s complaints were collected during anamnesis. Clinical examination identified signs associated with hyposialie and xerostomia. Stimulated and non‐stimulated saliva flow, pH and buffering capacity were verified. Results: The stimulated saliva flow in both groups was below normal parameters. The drugs used by individuals in G1 showed xerostomic potential. Individuals with a higher consumption of xerostomic medication presented with dry and cracked lips. A significant negative relationship was found between drugs consumption and the buffering capacity (p < 0.001), and the resting saliva flow rate (p = 0.002). Conclusion: The use of medication increases the chance that an elderly person may present signs related to xerostomia and alterations in stimulated saliva flow and buffering capacity.     

Effect of Menopause on Melatonin and Alertness Rhythms Investigated in Constant Routine Conditions

Although studies have reported the effects of the menstrual cycle on melatonin rhythmicity, none has investigated the effects of menopause on the melatonin rhythm. The circadian rhythm in melatonin and its relationship to subjective alertness was investigated in pre‐ and postmenopausal women under constant routine conditions (controlled posture, dim lighting, calorie intake, temperature, and prolonged wakefulness). Eleven healthy pre‐menopausal (42±4 yr) and 10 postmenopausal women (55±2 yr) participated in the study. Salivary melatonin samples and subjective measures of alertness and sleepiness were assessed hourly during the 22 h constant routine protocol. Postmenopausal women had a significantly earlier melatonin acrophase (1.1±0.5 h clock time in decimal h; mean±SEM, p<0.05) compared to the pre‐menopausal women (2.3±0.3 h). There was no significant difference between melatonin onset and amplitude between the pre‐menopausal and postmenopausal women. Self‐rated alertness declined in both study groups as the length of sleep deprivation increased. Melatonin onset preceded the onset of self‐rated sleepiness in both groups. The time interval between melatonin onset and the onset of sleepiness and alertness offset was significantly greater in the postmenopausal women compared to the pre‐menopausal women. In conclusion, under controlled experimental conditions the timing of the melatonin rhythm was advanced in postmenopausal women altering its phase relationship to subjective alertness and sleepiness.     

The influence of weight loss on serum osteoprotegerin concentration in obese perimenopausal women

Objective: To assess the influence of weight reduction therapy on serum osteoprotegerin (OPG) concentration in obese patients and compare these results with normal‐weight controls. Research Methods and Procedures: Forty‐three obese women (BMI, 36.7 ± 4.1 kg/m²; mean age, 50.1 ± 4.5 years) were studied. The control group consisted of 19 normal‐weight women (BMI, 24.2 ± 2.1 kg/m²; mean age, 53.8 ± 5.2 years). In all patients, serum concentrations of OPG, C telopeptide of type I collagen containing the cross‐linking site (CTX), osteocalcin, parathormone, 25‐(OH)‐D₃ (vitamin D), and total calcium and phosphorus were assessed before and after a 3‐month weight reduction therapy. Results: In obese subjects, serum concentrations of OPG, 25‐(OH)‐D₃, osteocalcin, total calcium, and phosphorus were significantly lower, and serum concentration of parathormone was significantly higher, before weight reduction therapy in comparison with normal‐weight controls. After weight reduction, a significantly higher serum concentration of 25‐(OH)‐D₃ and CTX and significantly lower concentration of OPG were found. Discussion: Serum concentration of OPG was significantly lower in obese patients in comparison with normal‐weight controls. Weight reduction therapy resulted in further decrease in OPG serum concentrations. Therefore, OPG cannot be treated as a protective factor from bone loss in obese patients.     

Impact of dry mouth conditions on oral health-related quality of life in older people

Objective: The aim of the present study was to evaluate the impact of dry mouth conditions on oral health‐related quality of life in frail old people, residents at community care centers. Further, reliability and validity of a visual analogue scale (VAS) for dry mouth symptoms were determined within the study cohort. Background: In old people functional, social and psychological impacts of oral conditions are associated with an overall sense of well being and general health. Subjective dry mouth and reduced saliva flow are common disorders in old people caused by disease and medication. Thus, dry mouth conditions may be determinants for compromised oral health‐related quality of life in old people. Method: In total, 50 old people living at service homes for the old people were asked to answer questionnaires on subjective dry mouth (VAS) and Oral Health Impact Profile (OHIP14) for oral health‐related quality of life. Saliva flow was estimated by absorbing saliva into a pre‐weighed cotton roll. Results: The final study cohort comprised 41 old people (aged 83–91 years). Significant associations were identified between both objective and subjective dry mouth and overall or specific aspects of oral health‐related quality of life. Conclusion: Dry mouth (objective and subjective) is significantly associated with oral health‐related quality of life strengthening the value of monitoring dry mouth conditions in the care of frail old people.     

Calcium metabolism in adult outpatients with epilepsy receiving long-term anticonvulsant therapy

Long-term anticonvulsant drug therapy may lead to abnormalities of calcium metabolism resulting in osteomalacia. The prevalence and severity of altered calcium metabolism was studied in an adult outpatient population of persons with epilepsy receiving anticonvulsant therapy for a minimum of 2 years. Assessment of calcium metabolism was based on serum concentrations of calcium, phosphorus, alkaline phosphatase and 25-hydroxycholecalciferol and of plasma parathyroid hormone, intestinal absorption of isotopic calcium and skeletal bone mineral mass as determined by in vivo neutron activation or x-ray photodensitometry.Thirty-nine patients who had been receiving anticonvulsant therapy for an average of 20 years were studied; none had clinical evidence of metabolic bone disease. Decreased serum calcium concentration was noted in 10%, decreased serum phosphorus concentration in 10% and elevated serum alkaline phosphatase concentration in 44%. The mean serum 25-hydroxycholecalciferol concentration was significantly lower (P < 0.001) than in a control group (11.6 v. 19.6 mg/mL). None of 18 patients studied had an increased plasma concentration of parathyroid hormone, and only 1 of 17 patients had decreased intestinal absorption of isotopic calcium. Bone mineral mass was decreased in 44% of 32 patients studied.It was concluded that long-term treatment with anticonvulsant drugs leads to mild abnormalities of calcium metabolism and decreased bone mineral mass in a substantial percentage of adult outpatients with epilepsy. These abnormalities probably predispose the patients to the development of clinically significant metabolic bone disease.     

CHARACTERISTICS OF PHOSPHORUS DEFICIENCY IN ANABAENA1

Several aspects of the metabolism and composition of a strain of Anabaena have been studied during phosphorus deficiency. The effects of medium composition, substrate concentration, temperature, pH, and illumination on alkaline phosphatase activity and phosphate uptake have been examined. Of particular interest among these results was the dependence of maximum alkaline phosphatase activity on Ca and of phosphate uptake on Mg. Depletion of dissolved phosphate from the culture medium runs accompanied by a marked increase in alkaline phosphatase activity, initial rate of phosphate uptake, and total amount of phosphate taken up to satisfaction of the phosphorus debt. Readdition of phosphate to a phosphorus-deficient culture resulted in a rapid decline in the ability to take up phosphate but no loss of alkaline phosphatase beyond dilution of activity already present. Entry into phophorus deficiency was accompanied by a loss of heterocysts, a decline in chlorophyll a, protein, RNA, and cellular phosphorus, and an increase in carbohydrate per unit dry weight. The possible use of these changes as physiological indicators of phosphorus limitation in natural situations is discussed.     

Relationships between the amount of saliva and medications in elderly individuals

Gerodontology 2010; doi: 10.1111/j.1741‐2358.2009.00358.x
Relationships between the amount of saliva and medications in elderly individuals Objective: To investigate medications that are related to volume of saliva in the elderly. Background data: In the elderly, many cases of mouth dryness may represent side effects of medication. Materials and methods: The volume of unstimulated saliva was measured for 30 s (cotton roll test), and with stimulation for 3 min (gum test) in 368 subjects 79–80 years old (177 men, 191 women). Medications were investigated using subject’s medication notebooks. Results: Mean volumes of unstimulated and stimulated saliva were 0.14 ± 0.13 and 4.30 ± 2.54 ml respectively. Significant differences were seen between gender and mean volume of saliva. The volume of unstimulated saliva was 0.16 ± 0.15 ml for men and 0.11 ± 0.10 ml for women. The volume of stimulated saliva was 4.99 ± 2.67 ml for men and 3.67 ± 2.25 ml for women. The percentage of subjects taking medication was 64.7% (238/368). Mean number of medications was 2.08 ± 2.26, with no significant difference with gender (2.01 ± 2.37 for men, 2.16 ± 2.16 for women). In a stepwise multiple regression analysis with volume of saliva as the objective variable and number of drugs by category as explanatory variables, significant explanatory variables in addition to gender and number of medications were blood‐coagulating agents, Ca antagonists and peptic ulcer drugs for volume of unstimulated saliva, and diabetes medications and peptic ulcer drugs for volume of stimulated saliva. Conclusion: These findings suggest that differences exist between gender in volume of saliva for elderly individuals, and that the volume of saliva is affected by the number and type of medications.
