Clinical Trial Summary
Rationale of study:
Separators placement is the primary step in orthodontic treatment and it is almost always
accompanied by pain and discomfort which has a direct impact on the compliance and quality of
life of patients. Many pharmacological methods over the past years have been recommended to
ease the pain and discomfort and make orthodontic treatment more acceptable .These methods
have adverse effects and hence it would be beneficial if we propose a method which will
satisfy the patients and will be suitable for them to follow with minimal side effects and
maximum efficacy.
Null hypothesis: lignocaine gel and chewing gum will be equally effective in reducing pain
after separator placement Alternative hypothesis: lignocaine gel will be more effective than
chewing gum in reducing pain after separator placement
Description:
Data will be collected from subjects reporting to the department of orthodontics, Karachi
Medical and Dental College. This study will be started after submission of the synopsis and
after approval of the Ethical Review Committee.
Following the placement of separators participant will be randomly assigned in to 2 groups.It
is a parallel group randamization.In this study the topical gel (lignocaine ) and a sugar
free gum that is commercially available is purchased from the local market. The composition
of lignocaine gel is given .Manual allocation using sealed envelope during enrolment of
patient in the study. This enabled approximately equal distribution of patients from each
group.
1. st group: Topical gel (lignocaine gel)
2. nd group: chewing gum In our study all the participant were asked to fill the
questionnaire. A written informed consent was acquired from all patients for inclusion
in the study.
In the topical gel group the patients were directed to apply the gel on the buccal free
gingival margin of their first molar at one side when the separators are placed and reapply
the gel every 8 hours . They were then requested to mark their level of pain at 2 and 8 hours
and at 10 pm of the 2nd,3rd,5th and 7th day after the gel is being applied and mark it on the
VAS form.
The patients in the chewing gum group were advised to chew sugar free gum for 5 minutes
immediately after separators were placed and at 8 hours interval. The patients were also
advised and motivated not to take any additional analgesics.
For measuring the perception of pain the most reliable method is the Visual Analog Scale
(VAS).It is a psychometric pain response scale.VAS is a measurement instrument for subjective
characters such as pain which cannot be measured directly.
The VAS form was filled in by the patients at baseline after separator placement at 2 hours,
at 8 hours , 24 hours, at 2nd day , 3rd day , 5th and 7th day after separator placement. When
replying to the VAS performa , the patients were requested to state their severity of pain by
marking a position along a calibrated straight continous line weighted at both ends by
descriptive terminology with a happy face and a sad face and document the severity of pain
when the jaws are at rest and during the biting activity.The degree of pain was determined
solely , based on patients conviction through VAS cards and questionnaire .
