Comparison of the effect of 4% Articaine and 2% Lidocaine infiltration during maxillary primary molar teeth extraction for 6-12 year-old children

Comparison of the effect of 4% Articaine and 2% Lidocaine infiltration during maxillary primary molar teeth extraction for 6-12 year-old children

In this randomized block clinical trial, 54 healthy children aged 6-12 years referred to the special clinic of Guilan Dental School who need to extract maxillary primary molars in both directions are selected. 2%lidocaine is used on one side and 4%articaine on the other side for local anesthesia of infiltration. Patients are randomly divided into two groups A and B.children select the appropriate face from Facial Image Scale after extraction. The pulse oximeter is used to record the baby's heartbeat while extracting teeth

Random block, 54 healthy children aged 6-12 years referred to the special clinic of Guilan Dental School who need to pull maxillary deciduous molars in both directions. 2% lidocaine is used on one side and 4% articaine on the other for local anesthesia of infiltration. Random sequences are placed in opaque sealed envelopes. Two blinds, an assistant evaluating the outcome, and the patient is unaware of the type of anesthetic.

Healthy cooperative children 6-12 years old who need to extract maxillary primary teeth - Parental consent - No allergic to anesthetic - No systemic problems - No drug that interferes with anesthesia

Control group 1.8 ml 4% articaine with epinephrine 1: 1000000 . Control group 1.5 ml lidocaine 2% with epinephrine 1: 80000

Complete anesthesia of the palatal tissue

In order to randomize people into two groups A and B, based on the description of the work method, permutation block randomization with block size 6 is used. Based on the order in which people enter the study, part of the randomization process is given below. The complete file is available as an Excel file (SAS version 9 software was used for randomization): Seed: 21650415094698 Block sizes: 6 Actual list length: 54 block identifier, block size, sequence within block, treatment • 1, 6, 1, Group A • 1, 6, 2, Group B • 1, 6, 3, Group A • 1, 6, 4, Group B • 1, 6, 5, Group A • 1, 6, 6, Group B • 2, 6, 1, Group A To select the right and left based on the allocation specified in the previous section based on the order specified by considering the left with the letter L and the right with R, the order of selecting the direction will be as follows: Seed: 21650415094698 Block sizes: 6 Actual list length: 54 block identifier, block size, sequence within block, treatment • 1, 6, 1, Group R • 1, 6, 2, Group L • 1, 6, 3, Group R • 1, 6, 4, Group L • 1, 6, 5, Group R • 1, 6, 6, Group L • 2, 6, 1, Group R • 2, 6, 2, Group L • 2, 6, 3, Group L

Random sequences are placed in opaque sealed envelopes. Two blinds, an assistant evaluating the outcome, and the patient are unaware of the type of anesthetic. It is not possible for the dentist to blind the material because the injection method is different and the dentist subconsciously notices.

Frequency and percentage are used to describe qualitative data And for quantitative data, mean and standard deviation will be used In addition, suitable descriptive tables and graphs will be used for both measurement scales. Shapiro-Wilk test is used to check the normality of the distribution of the groups and Levene test is used to homogenize the variances. To investigate the relationship and compare groups if the relevant assumptions are made from paired t-test and paired t-test and Generalized estimating equations (GEE) and if the assumptions are not made from Wilcoxon test and in case of no hypotheses for the GEE test, the appropriate conversions proposed by SPSS software (such as square root and logarithm) will be used to establish the hypotheses. . The software used will be spss version 26. Significance level in all tests will be considered 0.05.
