Chios Mastic Toothpaste and Halitosis and Oral Hygiene in Orthodontic Patients

January 3, 2025 updated by: Iosif Sifakakis, University of Athens

The Effect of Chios' Mastic Toothpaste on Halitosis and Oral Hygiene in Orthodontic Patients: a Randomized Clinical Trial

The aim of this trial was to investigate the effect of mastic toothpaste on halitosis using as proxy the levels of the Volatile Sulfur Compounds (VSCs), and the effect on plaque and gingival indices in adolescents undergoing orthodontic treatment with fixed conventional labial appliances.

Intervention / Treatment

Intervention / Treatment

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

  • Child
  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

Patients eligible for the trial must comply with all of the following at randomization:

• Age between 13 and 18 years for the group with conventional orthodontic appliances.

This age group represents the majority of patients seeking orthodontic treatment and is homogeneous regarding occupational status (high-school and lyceum students in Greece). Younger patients might present with cooperation problems.

  • Good general health.
  • Orthodontic fixed labial appliances on the maxillary and mandibular arch, brackets at least on 20 teeth for more than 4 months before enrollment and estimated duration of the treatment more than 1 month, bands on the first molars, extraction cases patients could be enrolled at least two months after the last extraction.
  • Total initial VSCs levels above the baseline level of 150ppb.

Exclusion Criteria:

Patients will be excluded for any of the following reasons:

  • Active caries
  • Periodontitis
  • Dental fluorosis / dysplasia of the teeth
  • Syndromes, mental disabilities and craniofacial deformities
  • Smoking or use of other tobacco products
  • Allergy to mastic
  • Antibiotics during the last 2 months
  • Chlorhexidine in the previous 3 weeks
  • Participation in other trials

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: Experimental group Mastic toothpaste
Experimental Group: patients, age 13-18, conventional brackets, Mastiha toothpaste 15 patients, with conventional brackets
Dietary supplement: mastic toothpaste
All 30 patients will be randomly assigned to either the mastic toothpaste group A (Mastiha Toothpaste Gingivaction, Mastihashop, Greece) (n = 15) or the placebo Toothpaste group B (from the same manufacturer) (n = 15). All patients will be asked to use the toothpaste triple a day for 14 days and to maintain their usual oral hygiene routine. The measurements will be done in the morning and at least three hours after brushing and without the use of the toothpaste by the participant on the day of the assessments.
Placebo Comparator: Placebo control arm: placebo toothpaste
Control Group: patients, age 13-18, conventional brackets, Placebo toothpaste 15 patients, with conventional brackets
Dietary supplement: Placebo toothpaste
All 30 patients will be randomly assigned to either the mastic toothpaste group A (Mastiha Toothpaste Gingivaction, Mastihashop, Greece) (n = 15) or the placebo Toothpaste group B (from the same manufacturer) (n = 15). All patients will be asked to use the toothpaste triple a day for 14 days and to maintain their usual oral hygiene routine. The measurements will be done in the morning and at least three hours after brushing and without the use of the toothpaste by the participant on the day of the assessments.

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
Modified plaque index (PI-M)
Time Frame: baseline - 2 weeks
The Silness and Löe index (Silness and Löe, 1964) does not take into account the pattern of plaque accumulation in orthodontic patients. To overcome this problem, Williams et al. (1991) divided the tooth into mesial, distal, gingival, and incisal regions in relation to the bracket and scored plaque in each region using the four codes of the original index (0 to 3). The values are summed to obtain a total score, which ranges from 0 to 12 for each tooth. This modified index is recommended for patients with fixed orthodontic appliances because it acknowledges the usual effects of orthodontic appliances on plaque distribution and has much greater categorical discrimination.
