Brief summary
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).
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.
Interventions
DEVICElower 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
DEVICERemovable 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

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of salivary flow of un-stimulated saliva | 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 |
| Assessment of salivary flow of stimulated saliva | 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 |
| Assessment of Salivary pH | before delivery of appliance, after 1 month, 3 months, 6 months | Salivary pH will be measured using an electronic pH meter |
| Assessment of viscosity of saliva | 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. |
| Assessment of buffering capacity | 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. |
