Durability of different types of Mouthwashes on the Salivary Buffering system in Orthodontic Patients.

Abstract

The fast elevation of the salivary pH in orthodontic patients has acritical role to safe the teeth and encourage the orthodontic treatment after acidic challenger. As their baseline salivary pH is dropped during fixed orthodontic treatments.Aims: this study was aimed to evaluate the durability of three types of mouthwashes on the salivary buffering capacity in orthodontic patients at 0, 5, 10, 15 mints after acidic challenger using direct pH meter.Material and method: 80 orthodontic patients; age range (13-21years) were distributed into four groups; 20/ each, the salivary pH were recorded using compact pH meter (LAQUAtwin, HORIBA's, Kyoto, Japan) before and after administration of carbonated beverage (100 mm coca cola) and directly after gargling with 100 ml of the tested mouthwashes (herbal, green tea and chlorohexidine mouthwash) beside tap water as placebo control. The pH was documented again at 0, 5, 10 and 15 mins after each mouthwash gargling. One way ANOVA analysis and Duncan multiple were used for salivary pH analysis, p≤0.05.Results: non-significant differences were found at 0, 5, 10, 15 mints in comparison with baseline pH after herbal mouthwash gargling, the same result was shown with chlorohexidine mouth wash but with less defined border. Salivary pH after green tea gargling showed clear oscillatory results after the same tested periods.Conclusions: Herbal mouthwash is the best type to improve salivary pH for longer duration after acidic challenger. While Chlorohexidine mouthwash shows beneficial effects in elevation salivary pH with less duration. Green tea mouthwash fail to control salivary pH for long duration.

The Effect of Oral Care Foams and a Spray on Salivary pH Changes after Exposure to Acidic Beverages in Young Adults

“…Coca-Cola ® is one of the world's most highly consumed commercial carbonated beverages [19] and has been shown to possess a high erosive potential [35,71,72]; therefore, in our study, we used rinsing with Coca-Cola ® to model a dietary acidic attack. A number of studies have shown that Coca-Cola ® decreased the salivary pH immediately after consumption [35][36][37]39,40], but generally it did not produce a decrease in salivary pH below 5.5 [35][36][37]. The pH value of 5.5 was found to be critical for enamel dissolution and caries development in vitro [56,61]; at the same time, in vivo this value varies over a wide range depending on the individual characteristics of the enamel and the content of mineral ions in plaque fluid and saliva [73][74][75].…”

“…The existing studies vary in experimental design, namely in their saliva collection conditions, type of exposure to soft drinks, and types of soft drinks assessed; therefore, their results are difficult to compare. In general, they found that soft drink consumption was associated with a salivary pH drop of different degrees [35][36][37][38][39][40], followed by a gradual recovery to baseline pH levels due to salivary clearance and buffering [36,38]. However, these protective mechanisms may not be sufficient in cases of a decreased salivation rate [35] or frequent exposure to acidic food or beverages [36].…”
