Effect of Fixed and Removable Space Maintainer on Some Salivary Parameters: An In-Vivo Study

January 5, 2024 updated by: Suez Canal University
The aim of this study is to evaluate and compare the effect of lower lingual holding arch space maintainer versus removable partial denture space maintainer on some salivary parameters (salivary flow rate, pH, viscosity and buffering capacity).

Study Overview

Detailed Description

This study is a randomized clinical trial, it will be conducted on forty children, aged from (7-10) years, who are in need for space maintainer.

  • Children will be randomly and equally divided into two groups according to type of space maintainer used; group (1): twenty children with lower lingual holding arch, group (2): twenty children with removable partial denture.
  • Un-stimulated and stimulated saliva will be collected at specific duration of time from children before the delivery of the appliance and after 1, 3 and 6 months of wearing the space maintainer to measure salivary flow rate, pH, viscosity and buffering capacity.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: children with lower lingual holding arch space maintainer
non functional fixed space maintainer used in the mandibular arch to maintain arch length by prevention of mesial movement of permanent first molar
lower lingual holding arch space maintainer is an orthodontic device which connects two molars lower dental arch. it has an archwire, adapted to the lingual side of the lower anterior teeth, that soldered to the bands on first permanent molar
Active Comparator: children with removable partial denture space maintainer
functional Removable space maintainer that not only maintain the mesiodistal space, but vertical dimension and masticatory function is also assured
Removable Partial Denture consists of a pink or gum-colored plastic base to which the new, artificial, replacement teeth are attached to. a metal framework holds the denture in place inside the mouth

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assessment of salivary flow of un-stimulated saliva
Time Frame: before delivery of appliance, after 1 month, 3 months, 6 months
Un-stimulated whole saliva will be collected from all individuals by direct expectoration into a sterile container over a period of 10 min by spitting method, so that the flow rate could be calculated by dividing the amount of expectorated saliva by 10 min
before delivery of appliance, after 1 month, 3 months, 6 months
Assessment of salivary flow of stimulated saliva
Time Frame: before delivery of appliance, after 1 month, 3 months, 6 months
To stimulate saliva, the subjects will be asked to chew a piece of paraffin wax, and saliva will be collected for 5 min in a measuring cup with 1ml gradation marks; the stimulated salivary flow rate (ml/min) will be calculated by dividing the amount of expectorated saliva by 5 min
before delivery of appliance, after 1 month, 3 months, 6 months
Assessment of Salivary pH
Time Frame: before delivery of appliance, after 1 month, 3 months, 6 months
Salivary pH will be measured using an electronic pH meter
before delivery of appliance, after 1 month, 3 months, 6 months
Assessment of viscosity of saliva
Time Frame: before delivery of appliance, after 1 month, 3 months, 6 months
Salivary viscosity will be determined by allowing saliva to flow through a tube of circular cross section to measure the flow rate . This will be done using the Ostwald viscometer.
before delivery of appliance, after 1 month, 3 months, 6 months
Assessment of buffering capacity
Time Frame: before delivery of appliance, after 1 month, 3 months, 6 months
By estimating the pH change after HCl titration into un-stimulated saliva for a buffering capacity test.
before delivery of appliance, after 1 month, 3 months, 6 months
