“…Dentinal pins are used for auxiliary retention for grossly carious teeth and to retain cores. [4][5][6][7][8] They have become increasingly less used as bonding techniques have become more predictable. Pre-clinical instruction aims to prepare the student to perform procedures on the patient, however, the correlation between pre-clinical and clinical grades have not shown to be significantly correlated.…”

OBJECTIVE: The objective of this study was to compare visuospatial and psychomotor skills of second year pre-clinical dental students with final year dental students using an exercise in dentinal pin placement. METHODOLOGY:A total of 120 BDS undergraduate students who had completed second or final year Operative dentistry rotation were included. While students from second and final year who had not consented to participate or had missed the practical demonstration or whose dentinal pins were misplaced after becoming loose from the tooth were excluded. Participating students placed the dentinal pins, following which Adobe Photoshop (version CC 2014) was used to analyze the photographs of the taken radiographs in two dimensions. Parameters assessed were pulpal perforations, periodontal perforations and pin angulation. Independent sample t-test was used to compare continuous variables while chi-square test was used for testing association for categorical variables. RESULTS: Final year students fared better in all categories of pin placement except periodontal perforation which was the same for both years. Statistically significant difference in the angulation for pin placement were observed between the two student groups in mesiodistal direction (p value =0.001) and in buccolingual direction (p value <.001). CONCLUSION: There is a significant difference in the psychomotor and visuospatial skill of second year pre-clinical when compared with the final year clinical undergraduate students. KEYWORDS: curriculum, dental, learning, operative, students.

Background:The aim of this study was to evaluate and compare relatively less explored fragment reattachment methods following traumatic injury.Materials and Methods:Eighty sound permanent maxillary incisors were selected and mounted in acrylic blocks. Teeth were sectioned using the diamond disc and randomly divided into 4 groups (n = 20), Group A, B, C, D. In Group A, after reattachment with composite, a 1 mm-depth circumferential chamfer was placed in the fracture line using a diamond disc bur and filled with composite. In Group B, two vertical grooves 1 mm deep, 1 mm wide, and 4 mm length were placed on the labial surface perpendicular to the fracture line and filled with two fiber-reinforced composite (FRC) posts and composite. In Group C, dentin is removed from the fragment and filled with composite. In Group D, the teeth were intact which served as control group. The force required to fracture the reattached teeth were recorded in Newton's using an onscreen calibration tool of the universal testing machine.Results:Teeth in Groups A, B, C required lesser force to fracture when compared with the teeth of the Group D. When compared to Group D, Group A showed a fracture resistance of 36%, Group B 62%, and Group C 32%.Conclusion:This study proves that reattachment by vertical grooves with FRC posts showed highest fracture resistance and it is the most preferred method. So far no attempt has been made to reattach fractured fragment using vertical grooves and reinforcing with FRC posts.
