Objective: The aim of our study was to determine the effect of two different types of removable appliances on periodontal health, dental plaque colonization, as well as saliva, pH, flow rate, and buffering capacity of the patients. Method: A total of 30 pediatric patients aged 7-12 years were treated with a total of 30 appliances including 15 clear aligners (Group A) and 15 labiolingual spring hawleys (Group B). In the clinical examination of the patients, dental caries status was evaluated by DMFT and dft index, periodontal health status was evaluated by probing pocket depth measurements and plaque, gingival and probing bleeding indices. In addition, saliva and dental plaque samples were taken and salivary parameters and microbiologic structure of plaque were analyzed. All these procedures were performed in 2 different time periods for each patient; before and after the treatment. The results were statistically evaluated using SPSS (SPSS Statistics v23.0 for Windows, Chicago, IL, USA).
In the clinical examination of the participants, dental caries status was evaluated by DMFT and dft index, and periodontal health status was evaluated by probing pocket depth measurements; PI, GI, SDI. In addition, saliva and dental plaque samples were taken and salivary parameters (flow rate, pH and buffering capacity) and microbiological structure of plaque were analyzed.

The effects of treatment on periodontal parameters (plaque index, gingival index, bleeding index on probing), salivary parameters (stimulated/unstimulated flow rate, stimulated/unstimulated pH, buffering capacity) and oral microorganism counts (S. mitis, S. salivarius, S. mutans, C. albicans) of children treated with labiolingual spring hawley and clear aligners were investigated.

PIaque index (PI)
Based on Silness-Löe (1963, 1967) PI values, bacterial plaque and plaque thickness in direct contact with the marginal gingiva are evaluated. The evaluation is made with the Williams-marked University of Michigan 'O' periodontal probe, and PI values are recorded from a total of 4 surfaces of each tooth included in the study, namely mesial, distal, buccal and lingual. The averages of these values are calculated for each patient. The average scores obtained are evaluated in the 0-3 score range. An increase in the calculated scores indicates that periodontal health is negatively affected.
Time frame: 3 months
DMFT index
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.
Time frame: 3 months
Oral microorganisms count
S. mitis, S. salivarius, S.mutans, C. albicans (cfu/ml)
Time frame: 3 months
Gingival index (GI)
The degree of gingivitis is assessed using the Silness-Löe (1963, 1967) GI. The average of the measurements taken from four sides of the tooth determines the GI score of the tooth, and the average of the measurements of all teeth determines the individual's gingival index score. The scores obtained are evaluated in the range of 0-3. An increase in the calculated scores indicates that periodontal health is negatively affected.
Time frame: 3 months
Bleeding on probing index (BOP)
In order to determine the inflammatory status of the pocket base and pocket epithelium, a score is given as positive (+) or negative (-) according to whether there is bleeding in the sulcus 20 seconds after the pocket depth measurement from a total of 4 surfaces of the teeth, mesial, distal, buccal and lingual. BOP is calculated as a score by dividing the number of bleeding teeth by the total number of tooth surfaces in each patient. An increase in the calculated scores indicates that periodontal health is negatively affected.
Time frame: 3 months
dft index
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.
