Background:
Incorporation of chromotherapy is an established modality in medical science. However, its use in adult dentistry is an unexplored area.
Aim:
This study aimed to clinically evaluate and compare the effect of chromotherapy on anxiety levels in patients undergoing endodontic treatment.
Materials and Methods:
Using computer randomization, the included 90 patients were divided into three groups: Group – 1: Blue, Group – 2: Pink, and Group – 3: Control. Patients were given a preoperative Modified Dental Anxiety Scale questionnaire. Preoperative assessment of heart rate, systolic blood pressure (BP), and diastolic BP was followed by color therapy. Assessment of all the parameters was done at three levels, i.e., preoperative, post chromotherapy session, and after endodontic treatment.
Statistical Analysis:
Obtained data were tabulated and subjected to ANOVA and
post hoc
Tukey's test, with
P
< 0.05 considered statistically significant.
Results:
The present study demonstrated that patients subjected to blue and pink color therapy had a statistically significant reduction in anxiety as compared to the control group after chromotherapy and post endodontic treatment (
P
< 0.05). However, between the pink- and blue-colored groups, no statistically significant difference was found (
P
> 0.05).
Conclusions:
Chromotherapy plays a pivotal role in anxiety reduction before and during the dental treatment procedure and can be effectively incorporated during routine practice.
Aim:
To evaluate and compare the effect of conventional and truss access cavity preparations on remaining dentin thickness (RDT), canal transportation, and centering ability in mandibular molars using cone-beam computed tomography (CBCT).
Methods:
Ethical approval was obtained before the commencement of the study. Thirty extracted mandibular molars were selected, disinfected, and stored in normal saline. Preoperative CBCT scans were taken for all the samples and randomly divided into two groups. (n = 15). Group A; Conventional access preparation group; Group B; Truss access preparation group. Cleaning and shaping were performed with the mesiobuccal canal of all the samples. Postoperative CBCT scans were compared with preoperative CBCT scans to evaluate the RDT, canal transportation, and canal centering ability in mandibular molar with conventional and truss access cavity preparation.
Results:
Data obtained from CBCT were analyzed by independent sample t-test with the P < 0.05 and found that RDT was higher in Group A as compared to Group B at the 3 and 9 mm levels, whereas it was higher in Group B at 6 mm level in both the mesial and distal side, but it was statistically insignificant at 3, 6, and 9 mm level. Canal transportation was higher in Group B than in Group A, but it was statistically insignificant at 6 and 9 mm levels but statistically significant at 3 mm. Canal centering ability was higher in Group A than in Group B, but it was not statistically significant at 3, 6, and 9 mm levels.
Conclusion:
Regarding RDT and canal centering ability, there is no statistically significant difference at all levels. Both groups present a statistically significant difference at 3 mm from the apex when comparing canal transportation. This suggests that conventional access cavity preparation is better than truss access preparation to maintain original canal anatomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
