Evaluation of microhardness and surface chemical charactristics of dental varnish fortified with nano-bioactive glass contains Strontium and Cobalt on permanent tooth:a clinical trial
Comparison of microhardness and surface chemical characteristics of dental varnish reinforced with nano-bioactive glass containing strontium and cobalt in intervention and control groups
Design
The intervention and control groups are determined in random manner using random numbers. The sample is 21 and blinding will be done and the effect of the intervention will be checked after 4 weeks.
Settings and conduct
The present clinical trial study will be conducted in Hamedan Faculty and in a simple random manner on patients who are undergoing orthodontic treatment. The teeth are numbered with a table of random numbers. The teeth of the intervention group will receive varnish, but the teeth of the control group will be dipped in distilled water to blind the patient. After 4 weeks when teeth are extracted microhardness and chemostructural properties are checked
Participants/Inclusion and exclusion criteria
Teeth can be included in our study that have a counterpart tooth on the opposite side and need to be pulled. The buccal surface of the mentioned teeth should be healthy and not have much decay
Intervention groups
Two premolar teeth of people who need to have their premolar teeth extracted due to orthodontics are used as a study sample. Fluoride varnish reinforced with nano-bioactive glass containing strontium and cobalt is applied to one of the premolar teeth with the corresponding tooth on the opposite side, and the other tooth receives distilled water. After 4 weeks from the beginning of the study, the aforementioned teeth are extracted and examined in laboratory conditions for microhardness and chemical surface characteristics.
Main outcome variables
Comparison of microhardness in the intervention and control group.; Comparison of chemostructural properties in the intervention and control group.

Number of samples in each individual:

Two premolar teeth of people who need to have their premolar teeth extracted due to orthodontics are used as a study sample. Fluoride varnish reinforced with nano-bioactive glass containing strontium and cobalt is applied to one of the premolar teeth with the corresponding tooth on the opposite side, and the other tooth does not receive that substance.
Randomization (investigator's opinion)
Randomized
Randomization description
Randomization will be done in a simple way with the help of a table of random numbers. For each even number, code A is assigned to apply varnish on the right premolar tooth, and for each odd number, code B is assigned to apply varnish to the left premolar tooth. Finally, a random chain of 21 letters A and B is formed with a random sequence. Cards A and B will be placed in the envelopes with numbers 1 to 21 in the order obtained, and upon the arrival of each patient who is eligible for the study, the corresponding envelope will be opened and the treatment group for that patient will be determined.
Blinding (investigator's opinion)
Single blinded
Blinding description
The teeth of the control group, which does not need to receive a substance, are dipped in distilled water to blind the participant, while the teeth of the intervention group receive varnish.
