Summary

Aim and background: The aim of this retrospective observational study is to evaluate the survival rate of cracked teeth, presenting partial (PVF) or complete vertical fracture (CVF), after tooth restoration either with fracture-fragment adhesive bonding or with amalgam restoration.

Materials and Methods: One hundred eight fractured teeth, from 99 patients (51 males, 48 females, mean age 50.5 years), presenting complete or partial root fracture, were treated with adhesive restoration or non-adhesive restoration protocol (amalgam) between 1991 and 2019. Demographic and clinical variables were evaluated as predictors of extraction. Furthermore, the bone loss/recovery due to therapy for the fracture was radiographically evaluated at the one year follow-up. All cases were treated by the same operator, using a surgical microscope. Statistical analysis was performed with IBM SPSS Statistics. The study was approved by the ethical committee of Sistema Sanitario Nazionale (prot. N°2370CELazio1).

Interventions

PROCEDURE

Adhesive restoration protocol

The canal walls were etched with 37% orthophosphoric acid for 30 seconds with use of a microbrush. The primer was applied on the wet canal walls, with a microbrush several times, after checking by drying the canal, that the appearance of the dentine was shiny and not opaque or chalky. The next step was the application of bonding with a microbrush, blowing in the fracture line to make sure it is not loaded with bonding. Flow composite was used to make it penetrate the fracture line with the help of a 0.06 mm k-file. The canals were filled with dual composite parts more deeply, light cured at the canal entrance and pulp chamber; the following phase was the coronal restoration with a sandwich technique, covering the cusp with composite.
