“…30,31 It has been suggested that the anatomy and physiology of the mouth, including interproximal spaces, occlusion and soft tissue anatomy may influence the retention or clearance or liquids in the mouth. [32][33][34] The multifactorial analysis completed by Al-Malik et al 28 also found a significant association between erosion and frequency of fizzy drink consumption, with an odds ratio of 1.46, but this was for 2-5-year-olds. The demonstration of increased risk is not the same as the identification of aetiology and attempts to show a causal relationship between risk factors and erosion have failed, although the sample sizes were small.…”

Objectives This study prospectively examines the relationship of possible aetiological factors to the presence of tooth erosion in a cohort of children. Patients and methods A random sample of 1,753 children was examined at age 12 and 1,308 of the same children were re-examined at age 14 years. The children were asked to complete questionnaires on both occasions, 1,149 subjects gave usable replies. The erosion index used was based upon the 1993 Survey of Children's Dental Health. Results were analysed using logistic regression. Results At age 12 significant positive associations were found between erosion and decay experience (odds ratio [OR]=1.48), drinking fruit juice (OR=1.42) or fizzy pop (OR = 1.59-2.52, depending on amount and frequency). The presence of calculus (OR 0.48) or eating fruit other than apples or citrus fruit (OR 0.48) reduced the chances of erosion. High consumption of carbonated drinks increased the odds of erosion being present at 12 years by 252% and was a strong predictor of the amount of erosion found at age 14. Conclusions Of the factors investigated, a history of dental caries and a high consumption of carbonated drinks were most closely related to the presence of dental erosion. The risk of erosion bore a strong relationship to the amount and frequency of carbonated drink consumption.It is only relatively recently that tooth erosion has been recognized as presenting a dental health problem in children. In 1993, the prevalence of erosion was reported as part of the national survey of Children's Dental Health in England and Wales 1 for the first time. Fifty per cent of 6-year-olds were found to have erosion and in 23% of children it had progressed into dentine. Thirty two per cent of 14-year-old children had erosion of the permanent dentition, with dentinal involvement present in 2%.The three main types of non-carious loss of dental hard tissue are attrition, abrasion and erosion. 2 Attrition implies removal of tooth surface due to movement of teeth against one another, pos-

“…During the recordings, subjects sat quietly with the head tilted slightly downwards so that any saliva in the mouth would drain forward. The subjects were told not to swallow (Lagerlof & Dawes, 1984) or to speak unless absolutely necessary. Nose breathing was encouraged to minimize drying of the oral mucosa (Cannon, 1918;Jenkins, 1978 Five healthy male volunteers took part in this experiment.…”

SUMMARYIn man, parotid flow has been recorded, using modified Lashley cups, in response to mechanical stimulation of the teeth by repeated chewing and clenching manoeuvres. The rectified and integrated masseter electromyographic activity was used as an indirect measure of the stimulus intensity where necessary. Following the observation that 'empty clenching' failed to evoke a parotid salivary response, a series of three experiments has been undertaken to address the following questions.(1) Is a lateral component of force required to evoke a flow during empty clenching?(2) Does contralateral inhibition of salivary secretion explain this observation? (3) What is the threshold for the masticatory-salivary reflex? The results suggest that: (i) empty clenching together with a lateral component of force does not result in a secretion above resting flows; (ii) there is no evidence for the existence of contralateral inhibition of salivary secretion; and (iii) the threshold for the masticatory-salivary reflex is lower than 5 % of comfortable chewing forces. We are still unable to offer an explanation for the lack of parotid secretion during empty clenching.

“…16,18 One of the functions of saliva is to regulate the pH of the oral environment by salivary buffers. 19 According to as a result, they obtained 1 ml/min saliva secreted under stimulation and 0.37 ml/min without stimulation. From a conservative perspective, taking into account the value of 1ml/min, the results presented in Table 2 and the data Graph 1: Representative of the pH behavior of a sample from each group, depending on the volume of saliva added proposed by Lagerlöf and Dawes 19 (1984), according to whom, when taking liquids, the remaining average volume in the oral cavity will be 1 ml, one can estimate that it will take 5 to 7 minutes, on average, to raise the pH level above 5.5 after taking cola-based drinks.…”

Objective: To assess the pH of regular and light cola-based drinks and energy drinks, and examine the acid neutralizing capacity by the addition of artificial saliva. Materials and methods:Ten packages of each product purchased locally at different stores were evaluated. The pH was measured by a pH-electrode calibrated in standard buffer solutions. To assess the pH neutralizing capacity, 1 ml/min of artificial saliva was added until a pH of 5.5 set as a cutoff point was reached in the tested solution. The data were subjected to analysis of variance (ANOVA), at the 0.05 significance level. Results:The surveyed beverages had an initial acidic pH, ranging between 2.3 and 3.4. The average amount of saliva required to raise the pH of the cola-based drinks above 5.5 ranged between 6.0 and 6.8 ml. Energy drinks used volumes between 11.3 and 12.5 ml; however, it was not possible to achieve a pH of 5.5. Conclusion:According to the methodology used, it was concluded that: (1) All beverages analyzed showed an initial acidic pH. (2) There was no statistical difference between the initial pH level and acid neutralization by the addition of artificial saliva in both regular and light drinks. It was not possible to reach the appropriate pH, set as the cutoff point, for the energy drinks.
