A Cross-sectional Study to assess the Perception of Psychosocial Elements among Pediatric Patients visiting Dental Clinics.

INTRODUCTION: Children with high dental fear and perception usually encounter high prevalence of dental caries. Data showed that individuals with dental fear will probably defer dental appointments which may result in the formation of a setup of an endless loop of dental fear. Present study was aimed to assess different psycho-social parameters among pediatric patients visiting dental clinics. MATERIALS AND METHODS: In the present cross-sectional study, the data of 200 schoolchildren were collected and analyzed by means of a questionnaire. Evaluation of the oral health status was done by experienced pedodontists. All the answers were recorded and analyzed by Statistical Package for the Social Sciences (SPSS) software. RESULTS: Nearly 120 were regular attendees while remaining 80 were found to be irregular attendees. Significant difference was observed while comparing the decayed, missing, and filled teeth (DMFT) index, decayed teeth, dental fear, cognitive vulnerability, and dental prevention belief between the regular and irregular group. Significant correlation was observed between higher number of decayed teeth and increasing level of dental fear. CONCLUSION: Various psychosocial parameters, by affecting the dental visits, are associated with outcome of oral health measures. CLINICAL SIGNIFICANCE: Special attention should be paid to the pediatric patients with such kind of behavior so that their psy-chosocial attitude could be modified in favor of dental treatment.

An in vitro Evaluation of Friction Characteristics of Conventional Stainless Steel and Self-ligating Stainless Steel Brackets with different Dimensions of Archwires in Various Bracket-archwire Combination.

AIM: The purpose of this research is to compare the frictional attributes of stainless steel conventional brackets and self-ligating stainless steel brackets with different dimensions of archwires. MATERIALS AND METHODS: The test was carried with two sets of maxillary brackets: (1) Conventional stainless steel (Victory Series), (2) stainless steel self-ligating (SmartClip) without first premolar brackets. Stainless steel, nickel-titanium (NiTi), and beta-Ti which are the types of orthodontic wire alloys were tested in this study. To monitor the frictional force, a universal testing machine (Instron 33R 4467) that comprises 10 kg tension load cell was assigned on a range of 1 kg and determined from 0 to 2 kg, which allows moving of an archwire along the brackets. One-way analysis of variance was used to test the difference between groups. To analyze the statistical difference between the two groups, Student's t-test was used. RESULTS: For Victory Series in static friction, p-value was 0.946 and for kinetic friction it was 0.944; at the same time for SmartClip, the p value for static and kinetic frictional resistance was 0.497 and 0.518 respectively. Hence, there was no statistically significant difference between the NiTi and stainless steel archwires. CONCLUSION: It is concluded that when compared with conventional brackets with stainless steel ligatures, self-ligating brackets can produce significantly less friction during sliding. Beta-Ti archwires expressed high amount of frictional resistance and the stainless steel archwires comprise low frictional resistance among all the archwire materials. CLINICAL SIGNIFICANCE: In orthodontics, frictional resistance has always had a major role. Its ability to impair tooth movement leads to the need for higher forces to move the teeth and it extends the treatment time which results in loss of posterior anchorage. Friction in orthodontics is related with sliding mechanics when a wire is moving through one or a series of bracket slots.

Comparative Evaluation of Neem Mouthwash on Plaque and Gingivitis: A Double-blind Crossover Study.

AIM: The present study aimed at evaluating the impact of neem-containing mouthwash on plaque and gingivitis. MATERIALS AND METHODS: This randomized, double-blinded, crossover clinical trial included 40 participants aged 18 to 35 years with washout period of 1 week between the crossover phases. A total of 20 participants, each randomly allocated into groups I and II, wherein in the first phase, group I was provided with 0.2% chlorhexidine gluconate and group II with 2% neem mouthwash. After the scores were recorded, 1-week time period was given to the participants to carry over the effects of the mouthwashes and then the second phase of the test was performed. The participants were instructed to use the other mouthwash through the second test phase. RESULTS: There was a slight reduction of plaque level in the first phase as well as in the second phase. When comparison was made between the groups, no statistically significant difference was seen. Both the groups showed reduction in the gingival index (GI) scores in the first phase, and there was a statistically significant difference in both groups at baseline and after intervention (0.005 and 0.01 respectively). In the second phase, GI scores were reduced in both groups, but there was a statistically significant difference between the groups only at baseline scores (0.01). CONCLUSION: In the present study, it has been concluded that neem mouthwash can be used as an alternative to chlorhexidine mouthwash based on the reduced scores in both the groups. CLINICAL SIGNIFICANCE: Using neem mouthwash in maintaining oral hygiene might have a better impact in prevention as well as pervasiveness of oral diseases as it is cost-effective and easily available.

Effect of prostaglandin E1 versus corticotomy on orthodontic tooth movement: an in vivo study.

BACKGROUND AND AIM: The aim of the present study is to compare the effect of corticotomy versus prostaglandin E1 injection in human subjects on rate of tooth movement, anchorage loss and their effect on crest bone height and root length. SETTINGS AND DESIGN: Clinical interventional study. Split mouth design was used. MATERIALS AND METHODS: Study was done on 32 regular orthodontic patients. A volume of 100 mcg of prostaglandin E1 was injected on the right side once in 2 weeks and on the left side corticotomy was performed, and canine retraction was started on both sides simultaneously. The rate of space closure and anchorage loss was assessed with casts. The root length and crestal bone height changes were assed with IOPAs. The comparison of rate of tooth movement, anchorage loss, crestal bone height and root length changes between the sides were statistically analyzed using paired t-test. RESULTS: The average rate of space closure on right side was 0.36 mm/week with a standard deviation of 0.05 mm/week and on the left side average rate of space closure was 0.40 mm/week with a standard deviation of 0.04 mm/week. The difference between the rate of closure between the right side and left where found to be statistically significant (P=0.003). The anchorage loss, the crestal bone height changes and root length changes were not statistically significant. CONCLUSION: The rate of tooth movement was significantly more with corticotomies when compared with given dose of prostaglandin injection.
