Trial 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. Read more about this study

About this study

Official title: EFFECTS OF SPACE MAINTAINERS ON THE SALIVARY pH, FLOW RATE, STREPTOCOCCUS MUTANS AND LACTOBACILLUS CARRIAGE: AN IN VİVO STUDY

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • The Salivary pH measuredOther

    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).

  • The saliva flow rate was measuredOther

    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.

  • Streptococcus mutans and Lactobacillus counts in saliva were measuredOther

    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.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

FOR FıXED SPACE MAıNTAıNERS: CHANGES ON THE SALIVARY pH WERE MEASURED (time frame: baseline-1st month measure assessing change). The study lists 24 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2021; AzTrials last refreshed its copy on 27 Oct 2026.
