Comparative Evaluation of Fracture Resistance of Endodontically Treated Teeth Restored with Different Core Build-up Materials: An In Vitro Study.

The aim is to evaluate the fracture resistance of endodontically treated teeth restored with posterior direct composite (PRC) resin, bulk-fill composite resin, dual-cure composite (DCC) resin, and short fiber-reinforced composite (SFC) resin material. MATERIALS AND METHODS: Ninety sound maxillary premolar teeth were divided into 6 groups which comprised 15 teeth each. Group I was a negative control group where neither cavity preparation nor root canal treatment was done on the specimen. Group II was named positive control group as it was left unrestored after mesio-occluso-distal (MOD) preparation and root canal treatment. Groups III to VI were filled with PRC, bulk-fill composite, DCC, and SFC, respectively, and subjected to fracture testing in a universal testing machine. RESULTS: After statistical analysis, it was seen that group VI had increased mean fracture resistance as compared to other groups. CONCLUSION: It was concluded that short fiber-reinforced composite proved to have superior properties that other experimental groups and hence can be used as a core build-up material. CLINICAL SIGNIFICANCE: The core build-up is requisite as the residual tooth structure after endodontic procedure decreases and core build-up supplements the resistance and retention of the tooth structure.

Plaque Removal Efficacy of Different Toothbrushes: A Comparative Study.

AIM AND OBJECTIVE: This study aimed to compare the plaque removal efficacy of different toothbrushes and to ascertain the most efficient mechanical mean for daily plaque removal so as to maintain oral health in a preeminent way. STUDY DESIGN: It was a randomized controlled clinical trial consisting of 60 subjects divided into three groups (group I ultrasonic and sonic toothbrush, group II multidirectional toothbrush, and group III manual toothbrush) with 20 in each group. Prebrushing and postbrushing plaque scores were recorded at weekly intervals for four weeks using Turesky modification of Quigley and Hein plaque index. RESULTS: Statistically significant differences (p < 0.001) existed in mean percent reduction of pre-day 1 to pre-day 28 mean percent reduction in plaque values of the ultrasonic toothbrush group (111.92 ± 25.20), the multidirectional toothbrush group (189.06 ± 52.70), and the manual toothbrush group (42.34 ± 14.77). Similar results were found in post-day 1 to post-day 28 mean percent reduction in plaque values. CONCLUSION: Group II (i.e., multidirectional toothbrush) showed maximum mean percent reduction in prebrushing and postbrushing plaque scores at the end of four weeks when compared with the baseline values followed by ultrasonic toothbrush and manual toothbrush.

A novel Chotta Bheem-Chutki scale for dental anxiety determination in children.

OBJECTIVE: A potential problem in patient management in pediatric dentistry is dental anxiety among children. It is of paramount importance for pediatric dentists to identify an anxious child and review potential management options specific to every child. The aim of this study is to validate a newly devised Chotta Bheem-Chutki (CBC) pictorial scale and to compare this with Venham's pictorial scale (VPS) and facial image scale (FIS) to measure dental anxiety in young children during their first dental visit. MATERIALS AND METHODS: One hundred children aged 4-12 years were randomly selected from our hospital outpatient department. Child's anxiety levels were measured using three different scales; the VPS, FIS, and the newly devised CBC pictorial scale. The scores were recorded by asking the children to choose the figure they identified with at that instant. The scores obtained from all the three scales were compared using student's t-test. Pearson correlation test was used to obtain correlation among the scales used in the study. RESULTS: A strong correlation (0.778) was found between FIS and CBC scale. Moreover, a strong correlation (0.811) was found between VPS and CBC scale, indicating good validity of the CBC scale. Seventy five percent of the children found CBC scale to be the easiest among the three scales. CONCLUSION: The findings of this study suggest that CBC scale can be used as a new tool for dental anxiety assessment in children.

Management of grossly decayed primary anteriors using various intracanal post systems: A clinical study.

PURPOSE: The aim of the present study was to clinically evaluate and compare the efficacy and retention of various types of intracanal posts in the restoration of grossly decayed deciduous anterior teeth. The various posts used were polyethylene post, glass post, and composite post. MATERIALS AND METHODS: A total number of 16 patients with 45 grossly decayed primary anterior teeth were selected. After biomechanical preparation and obturation, patients were randomly divided on the basis of posts to be used into three groups (Group I: Polyethylene post; Group II: Glass post, and Group III: Composite post). Then, space was created in the obturated canal and posts were placed, followed by core build up. RESULTS: After an interval of 12 months, 86.67% of the teeth exhibited complete retention of the post restored with polyethylene post (P > 0.005) and 93.3% of the teeth exhibited complete retention of the post that were restored with glass post (P > 0.005) whereas only 60% of the teeth exhibited complete retention of the post that were restored with composite post (P< 0.005). Only 20% of the teeth exhibited marginal discoloration in both Groups I and III and 13.33% in Group II and this was nonsignificant. CONCLUSION: Both glass post and polyethylene post proved to be effective. Glass post showed the maximum retention and marginal adaptation followed by polyethylene post. Thus, it appears to be of potential interest for use especially in clinical pediatric dentistry.

Glassfiber post: an alternative for restoring grossly decayed primary incisors.

Restoration of primary incisors, which have been severely damaged by rampant caries or trauma, is a difficult task for the pediatric dentist. With the introduction of new adhesive systems and restorative materials, alternative approaches for treating these teeth have been proposed. This paper discusses the restoration of carious primary maxillary incisors using composite resin restoration reinforced with fiberglass post. Two case reports are presented here to describe the procedure. Over a 1 year period, the crowns have demonstrated good retention and esthetic results. How to cite this article: Mehra M, Grover R.
