Summary

Space maintainers are used to preserve the space after premature loss of teeth but they could effect some factors that play a role in caries formation. The research aimed to assess the impacts of removable and fixed space maintainers on the salivary pH, flow rate, and Streptococcus mutans, Lactobacillus carriage.

Detailed description

Although the usage of space maintainers can reduce the severity of problems that arise from the early loss of teeth, there are concerns regarding the impact of fixed and removable appliances on factors that can lead to dental caries. All space maintainer appliances are plaque retentive since bands and brackets increase the retention of plaque and food on tooth surfaces, reduce the clearance of plaque by saliva and make conventional oral hygiene for plaque removal more difficult, therefore, they may cause caries development.Space maintainers can favor caries formation by changing the oral microflora. patients aged between 4-10 years, each of whom had an indication for a fixed (n=19) or removable space maintainer (n=19), were enrolled in this research. The salivary pH, saliva flow rate, Streptococcus mutans and Lactobacillus counts in saliva were measured just prior to the application of space maintainers (baseline-T0) and in the course of the follow-up; at the 1st (T1), 3rd (T2), and 6th (T3) months. The Wilcoxon, Mann-Whithney U test and Friedman tests were used for statistical analyses.

Conditions

• Orthodontic Appliance Complication
• Lactobacillus Infection
• Dental Caries in Children
• Streptococcus, Other Specified Group

Interventions

Type	Name	Description
OTHER	The Salivary pH measured	The saliva samples were obtained at 10-12 a.m. from all children. The saliva was collected into plastic cylinders and the salivary pH was measured with a pH meter (Compact pH meter B-212 twin pH, HORIBA, Osaka, Japan).
OTHER	The saliva flow rate was measured	The saliva flow rate was estimated by during the first 30 s of paraffin chewing. The saliva was collected into plastic cylinders for a period of 5 minutes. Afterward, the saliva were weighed with a in a precision balance (Mettler PC 400, Zurich, Switzerland) and the flow rate was computed in gms/ml.
OTHER	Streptococcus mutans and Lactobacillus counts in saliva were measured	The saliva samples were obtained according to described above. Numbers of colony-forming units (CFU) of S. mutans were counted on TSY20B agar and Lactobacilli were counted on Rogosa agar.
