RESUMEN
Children's conduct is significantly impacted by pain during dental procedures. Children's pain and discomfort can be reduced using computer-controlled local anesthetic delivery, which applies a steady, gradual flow of the anesthetic solution into the tissues. Using a self-report anxiety scale, the study aimed to assess and compare children's perceptions of discomfort following a new auto-controlled injection method to a traditional local anesthetic procedure. A total of 25 children, ages 6-12 requiring the use of local anesthesia for treatment on both sides of the arch were selected. It was a split-mouth design, in which each participating child received both types of infiltrations in two separate, consecutive visits, using a metallic syringe in one session, and using the I-Ject device in the other. Before administering anesthesia, all the children's anxiety scales were recorded using the Modified Child Dental Anxiety Faces Scale simplified to assess the anxiety level of a child. In the first appointment, Conventional anesthetic technique was and in the second appointment anesthesia was delivered using a computer-controlled device. Faces pain scaleRevised, a selfreport measure of pain was recorded immediately after completion of both types of local anesthesia (LA) administration. Patients reported greater comfort with the I-Ject computer-controlled device than with conventional anesthesia. Together with the practitioner, the computer system produced a pleasant and cozy environment for the youngster.
RESUMEN
AIM: This study aims to evaluate the relation between salivary proteinase 3 (PR3) concentration and caries severity in children. MATERIALS AND METHODS: Six-to-eight-year age group children, from the Outpatient Department of Pediatric and Preventive dentistry at PMS Dental College were selected for the study. From these children, three groups each consisting of 28 children were selected according to the dental caries severity. Three groups were: (1) No Dental Caries group, (2) Low Dental Caries group with DMFT/DEFT score of 1-4, and (3) High Dental Caries group with DMFT/DEFT score of 5-15. Thus, a total of 84 children who satisfied the inclusion criteria were selected. The concentration of PR3 in saliva of the donors were analyzed using an ELISA kit. One way ANOVA was used for finding the relation of salivary PR3 concentration with caries severity. Pairwise comparison of PR3 concentration and caries severity were analyzed using post hoc Tukey test. RESULTS: Severity of caries and concentration of salivary PR3 showed an inverse relation. As the caries severity increases there was a decrease in PR3 concentration and vice versa. CONCLUSION: The children with high caries severity showed lower concentration of PR3 in their saliva compared with those with lower caries severity which indicates that PR3 can be used as a biomarker for assessing caries severity and also paves way to use PR3 as a caries vaccine in future. Nowadays, interest toward noninvasive and personalized dentistry has been increased. Molecular assays using salivary biomarkers can be an effective tool in detecting the caries in earlier stages and assessing a patient's caries risk. CLINICAL SIGNIFICANCE: Salivary PR3 can be used as prognostic biomarker for assessing caries severity and after treatment the value of PR3 can be used as a assessment tool to confirm its relation with caries.
