Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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
Device: lower lingual holding arch space maintainer
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
Device: Removable partial denture space maintainer
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

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
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
