Evaluation of Familial Mediterranean Fever (FMF) Impact on Oral and Dental Health in Children and Adolescents

Aim: It is the clinical and radiological evaluation of oral hygiene, teeth and surrounding tissues in children and adolescents diagnosed with FMF and comparing the results with healthy individuals. Method: Our study included patients aged 6-15, 45 with FMF (study group) and 45 healthy (control group), who were referred from Akdeniz University Faculty of Medicine Pediatric Rheumatology Clinic and evaluated at Akdeniz University Faculty of Dentistry Pedodontics Clinic. MEFV gene mutations were investigated in the study group. After recording the demographic and clinical characteristics of both groups, intraoral examinations were performed and DMFT, dft, bruxism, tooth wear due to bruxism and gingival/plaque indexes were evaluated. Saliva pH, flow rate and buffering capacity were measured. Tooth age was determined by the Cameriere method, The mesio-distal dimensions of the teeth were measured on the plaster model.

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

Experimental: Study group with FMF
The study group was named 'Study group with FMF'.
Other: FMF Study Group
In the study group consisting of children with FMF, DMFT, dft, bruxism, tooth wear due to bruxism, gingival index (MGI), plaque index (OHI-S), salivary pH, salivary flow rate, salivary buffering capacity, dental age, chronological age difference, mesio-distal dimensions of the teeth, and the presence of aphthous lesions were determined.
Experimental: Healthy control group
The control group consisting of healthy participants was called 'Healthy control group'.
Other: control group
In the control group consisting of healthy children, DMFT, dft, bruxism, tooth wear due to bruxism, gingival index (MGI), plaque index (OHI-S), salivary pH, salivary flow rate, salivary buffering capacity, dental age, chronological age difference, mesio-distal dimensions of the teeth, and the presence of aphthous lesions were determined.

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
DMFT index
Time Frame: 3 months
To determine the DMFT index score, decayed teeth in permanent teeth are indicated as "D", lost teeth extracted due to decay are indicated as "M", and filled teeth are indicated as "F". The DMFT index is calculated by adding the D, M, F values and dividing them by the total number of permanent teeth. An increase in the calculated scores indicates that oral and dental health is negatively affected.
3 months
dft index
Time Frame: 3 months
The dft Index is the calculated form of the DMFT index for primary teeth. When calculating the dft group index, missing teeth are not included in the calculation. Because it is difficult to diagnose the reason for the loss of primary teeth and there is a high probability of error. For this reason, the number of decayed and filled teeth is calculated during the examination. Decayed teeth are indicated with "d" and filled teeth with "f". The dft index is calculated by adding the d and f values and dividing them by the total number of permanent teeth. An increase in the calculated scores indicates that oral and dental health is negatively affected
3 months
Saliva pH
Time Frame: 3 months
Salivary pH was measured using pH indicator strips. A low pH (<6.5) indicates an acidic environment and increases the risk of tooth demineralization and caries, whereas a high pH (>7.5) indicates an alkaline state, which may be linked to decreased bacterial activity but may also indicate systemic conditions.
3 months
Unstimulated salivary flow rate
Time Frame: 3 months
Unstimulated salivary flow rate is measured by collecting unstimulated saliva over a period of time and calculating the volume per minute. A low flow rate (<0.1 mL/min) indicates hyposalivation, which increases the risk of caries and oral infection, while a high flow rate may be associated with conditions such as gastroesophageal reflux or medication effects.
3 months
Saliva buffering capacity
Time Frame: 3 months
Saliva buffering capacity was measured using the GC Saliva Buffer Kit, which uses a scoring system based on color changes. A low buffering capacity indicates a higher risk of dental caries and enamel demineralization, whereas a high buffering capacity indicates better protection against acid attacks in the oral environment.
3 months
Simplified Oral Hygiene Index (OHI-S)
Time Frame: 3 months
The Simplified Oral Hygiene Index (OHI-S) assesses oral cleanliness by measuring debris and calculus accumulation on selected tooth surfaces. Higher scores indicate poorer oral hygiene, while lower scores suggest better maintenance.
3 months
The Modified Gingival Index (MGI)
Time Frame: 3 months
The Modified Gingival Index (MGI) evaluates gingival inflammation without probing, based on visual inspection. Higher scores reflect increased inflammation and potential periodontal issues.
