“…The wearing of dentures was also significant for these micro-organisms, a finding in accordance with other studies of the elderly, where higher counts of lactobacilli and/or mutans streptococci were found in persons wearing removable dentures than in dentate individuals with no dentures Köhler and Persson, 1991;Beighton et al, 1990;Marsh et al, 1992;Närhi et al, 1994;Lundgren et al, 1996]. These microbial findings indicate a general change towards a more aciduric flora in the elderly, which is also emphasized by the finding of an increased amount of yeast with age or in association with the wearing of dentures in some studies [Parvinen and Larmas, 1982;Marsh et al, 1992;Beighton et al, 1990]. The reason for this is not quite clear.…”

“…In one study, a decrease with age for only stimulated but not for unstimulated whole saliva was found [Närhi et al, 1992], while the opposite finding of a decrease with age for unstimulated but not for stimulated salivary flow was found in another study [Ben-Aryeh et al, 1984]. Furthermore, other authors have reported insignificant differences in terms of age for the secretion rate of stimulated whole saliva [Parvinen and Larmas, 1982;Österberg et al, 1992]. No age-related diminution in the salivary output of the major glands, i.e.…”

The 5-year incidence of dental caries in a random sample of 60-, 70- and 80-year-old inhabitants of Göteborg was related to salivary and microbial conditions. Of the 208 persons examined at baseline, 148 (71%) participated in the follow-up examination; 69, 51 and 28, respectively, in the different age groups. The study revealed that 27% of the participants had not developed any carious lesions during the 5-year period and that the incidence of coronal and root caries increased with age. In the 60-year-olds, 2.5% of the susceptible coronal and root surfaces, respectively, had decayed, while the corresponding figures for the 80-year-olds were 8.8% for coronal surfaces and 9.8% for root surfaces. In all, 18% had an unstimulated saliva secretion rate of below 0.1 ml/min and 14% had a stimulated secretion rate of < 0.7 ml/min, with a mean rate which decreased with increasing age from 2.0 to 1.6 and 1.3 ml/min (p = 0.02). The overall salivary counts of lactobacilli and mutans streptococci, particularly the subspecies of Streptococcus sobrinus, had increased during the period. In the respective age groups of 60, 70 and 80 years, 15, 39 and 39% had a mutans streptococci count of ≥ 10⁶ CFU/ml in saliva and the corresponding figures for ≥ 10⁵ lactobacilli counts were 22, 31 and 43%. In the stepwise regression analysis, it was found that age, salivary levels of mutans streptococci and lactobacilli and number of teeth were the best predictors of the incidence of root caries. In conclusion, these observations indicate that there is an increased risk of dental caries with age owing to unfavourable microbial and salivary conditions.

“…However, many studies concerning the hormonal influence on salivary function and its relation to oral health are not conclusive. Several studies report no changes in salivary flow rates after the menopause as compared with the reproductive years [4,23], while other studies [24,25] show lower whole salivary flow rates in postmenopausal women and in women during pregnancy. The objective of this study is to assess salivary flow rates across menopausal status in a cohort of healthy Caucasian women of varying ages.…”

Effects of Estrogen Status and Aging on Salivary Flow Rates in Healthy Caucasian Women

A comparison of salivary flow rates was made between three groups of female individuals according to their menopausal status. The three groups consisted of healthy, dentate, nonmedicated women (with the exception of the use of estrogen) from the Baltimore Longitudinal Study of Aging. One group consisted of premenopausal women (n = 51), their mean age was 39 years. Another group (n = 26) was perimenopausal with a mean age of 48 years. A third group (n = 76) was postmenopausal with a mean age of 69 years. The groups were evaluated for unstimulated (U_PAR) and stimulated parotid gland flow rates (S_PAR), unstimulated (U_SUB) and stimulated submandibular/sublingual gland flow rates (S_SUB), and stimulated whole-saliva flow rates (S_WHOLE). The parotid flow rates were determined using a Carlson-Crittenden cup, while the submandibular/sublingual flow rates were determined using the National Institute of Dental Research collector. A 2% citrate solution was used for stimulation in glandular collections. Chewing a 1-cm³ cube of paraffin was used to stimulate whole saliva. The results showed no significant differences in U_PAR, S_PAR, and S_WHOLE between the three groups. However, the premenopausal women had higher U_SUB than the postmenopausal group. The premenopausal women also had higher S_SUB than perimenopausal and postmenopausal groups. There were no differences in salivary flow rates between those taking estrogen and those that were not medicated.

“…2 En contraste, Sáez y colabodores (2007), reportaron que en las mujeres la reducción del flujo salival se acentúa después de la menopausia más exactamente después de los 60 años. 15 Estos resultados fueron similares a los obtenidos por Parvinen y Larmas, quienes realizaron un estudio en 117 mujeres finlandesas mayores de 50 años de edad posmenopáusica; 16 no obstante estas diferencias no fueron significativas. Cabe la preocupación de modificar hábitos para elevar la tasa de flujo de saliva en mujeres en edades mayores de 40 años ya que al parecer los cambios hormonales se relacionan con bajas en la cantidad de saliva secretada y se ha demostrado la relación directa entre flujo disminuido y caries dental.…”

RESUmENObjetivo: Relacionar las características salivales con presencia de caries y cálculos dentales en pacientes adultos mayores que asisten a las Clínicas Odontológicas de la Universidad Santo Tomás en Bucaramanga. Materiales y métodos: Se realizó un estudio de corte transversal en una población de 46 personas mayores de 50 años. Las variables dependientes utilizadas fueron pH, aclaramiento y flujo salival, las independientes fueron las sociodemográficas, caries coronal, caries radicular, cálculo dental y hábitos de higiene. Los datos fueron tabulados y analizados estadísticamente con el Test Chi 2 y el exacto de Fisher para variables cualitativas y para variables cuantitativas t Student. Resultados: La prevalencia de caries coronal fue del 65,2% y de caries radicular fue del 34,8%. El consumo de medicamentos es un posible factor de riesgo para el aumento de pH salival. El 84,8% de la población tienen tiempo de aclaramiento mayor de 15 minutos. El flujo salival elevado se considera un factor de riesgo para el pH salival básico (RP 1,54) y para presencia de cálculo dental. Un porcentaje considerable de mujeres (51,7%) presentó flujo salival estimulado disminuido mientras que apenas el 11,8% de los hombres reportó esta característica. Conclusiones: La tasa de flujo salival estimulado disminuido prevalece más en las mujeres que en los hombres; tener 56 años o más, aumenta el riesgo de disminución en flujo salival estimulado, y éste se relaciona directamente con mayor presencia de cálculo dental que resulta ser un condicionante de acúmulo de placa que provoca caries radicular en los adultos mayores.

SALiVARY CHARACTERiSTiCS RELATED TO DENTAL CARiES AND DENTAL CALCULLUS iN PEOPLE OVER 50 YEARS ABSTRACTObjective: To relate the characteristics and presence of dental caries and salivary calculus in elderly patients that attended the Dental Clinics at Santo Tomas University in Bucaramanga. Methods: A cross sectional study was done with 46 people over 50 years. The dependent variables used were pH, clearance and salivary flow, the independent variables were sociodemographic, coronal caries, root caries, dental calculus and dental hygiene. Data were tabulated and analyzed statistically using Chi 2 test and Fisher exact test for qualitative variables and Student t test for quantitative variables. Results: The prevalence of coronal caries was 65.2% and root caries was 34.8%. The consumption of drugs is a possible risk factor for the increase in salivary pH. 84.8% of the population has higher clearance time of 15 minutes. High salivary flow is considered a risk factor for salivary pH basic (OR: 1.54) and presence of dental calculus. A considerable percentage of female (51.7%) had decreased stimulated salivary flow while only 11.8% of men reported this feature. Conclusions:...
