A recent systematic review found that post\u2010bonding reinforcements could reduce the risk of loss of attached fragments in teeth with uncomplicated and complicated crown fractures. Hence, this study aimed to compare various techniques of reinforcement in terms of the force required to fracture, using bovine incisor models with simulated uncomplicated crown fractures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This in\u00a0vitro study was initiated after obtaining approval from the Institutional Ethics Committee. The sample size was calculated as 20 teeth per group, and bovine mandibular incisors were carefully evaluated for size and absence of structural defects and randomly allocated to four groups (Group I\u2010 Simple Reattachment, Group II\u2010 External Chamfer, Group III\u2010 Over contouring, Group IV\u2010 Sound teeth). Those in experimental groups were subjected to a fracture protocol, kept dry at room temperature and atmospheric pressure for 24\u2009h, rehydrated for 15\u2009min, and bonded using simple reattachment. The post\u2010bonding reinforcement protocols were followed for Groups II and III. Samples were stored in normal saline, and thermocycling was performed. A universal testing machine was used to assess the force required to fracture.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The least magnitude of force required for fracture was seen in Group I, while the highest was seen in Group III (164.75\u2009\n                      <jats:italic>N<\/jats:italic>\n                      ). The force in Group I was significantly lower compared to all the protocols of post\u2010bonding reinforcement and the control teeth (Group IV).
