June 19, 2017 updated by: Zeinab mohamed, Cairo University

Satisfaction Of Adult Patients With Gummy Smile Treated By Botulinum Toxin A Injection Versus Modified Lip Repositioning Surgery : A Randomized Clinical Trial

The aim of the proposal study is to answer the question of how to manage gummy smiles due to hypermobile upper lip with less invasive and low risk level procedure . This trial will help the practitioners and the patients in taking the convenient decision to correct the gumminess to restore lip-gingival-dental harmony and enhance smile asthetics.

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

In this randomized clinical trial , two groups will be included to compare the effectiveness of a treatment modality of botulinum toxin-A injection , in the first group , on gingival display during smiling ,patient satisfaction , lower face esthetics ( upper lip length , upper lip vermillion length , interlabial gap , nasolabial angle) and the postoperative side effects . the comparator group will receive treatment by modified lip repositioning surgery ,to compare the results of the intervention group that can possibly obtained without undergoing surgery.

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.

Ages Eligible for Study

18 years to 30 years (ADULT)

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

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

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.
EXPERIMENTAL: Botulinum Toxin A Injection
this group will receive Botulinum Toxin A Injection at doses of 2.5 or 5 IU (depending on the degree of gum exposure) on each side of the nasolabial fold with follow up at at 2,4,8,12 and 24 weeks.
Drug: Botulinum Toxin A Injection
adult patients with gummy smile due to hypermobile upper lip will receive Botulinum Toxin A Injection with a single injection1 cm lateral to the ala horizontally and 3 cm above the lip line vertically.
Other Names:
  • BOTOX
EXPERIMENTAL: Modified Lip Repositioning Surgery
this group will receive Modified Lip Repositioning Surgery with follow up at at 2,4,8,12 and 24 weeks.
Procedure: Modified Lip Repositioning Surgery
the surgical procedure will be done by removal of strip of epithelium by careful dissection and stabilizing the new mucosal margin to the gingiva to improve the gingival display in adult patients with gummy smile.

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
Patient satisfaction and postoperative side effects
Time Frame: at 4 weeks
it will be assessed using Questionnaire.
at 4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Improvement of gingival display upon smiling
Time Frame: at 4,8 and 12 weeks
it will be assessed using Digital ruler on DSS software
at 4,8 and 12 weeks

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2017

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
