There is a paucity of literature regarding management of fragment reattachment cases following a further fracture. Hence the aim of the present <jats:italic>in\u2010vitro<\/jats:italic> study was to evaluate and compare the efficacy of three different management protocols for such scenarios.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methodology<\/jats:title><jats:p>Eighty maxillary bovine incisors without structural deformity and with similar dimensions were fractured as per the standard protocol. They were subjected to drying for 24\u00a0hours and the fragments were rehydrated by placing them in a humidification chamber for 15\u00a0minutes. They were then reattached by using flowable light\u2010cured composite resin. The teeth (n=20) were fractured again by fixing them in a mechanical frame and using a mallet. They were randomly allocated to three experimental groups. (Group I mechanical abrasion and fragment reattachment, Group II mechanical abrasion, humidification and reattachment, Group III mechanical abrasion and composite restoration, and Group IV positive control with no re\u2010fracture). The samples were thermocycled and the force required to fracture was tested by using a universal testing machine (Instron\u20103360, USA). This was done by applying a tangential load with a speed of 1\u00a0mm\/min to the teeth with a 500\u2010kg load cell. Statistical analysis of the results was performed using ANOVA and the independent t\u2010test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The highest force required to fracture was reported in Group IV (333.26 \u00b1 66.69N) while the lowest was in Group II (254.86 \u00b1 105.23N). The forces in Group I and Group II were 258.36 \u00b1 65.78N and 298.02 \u00b1 97.94N, respectively (<jats:italic>p<\/jats:italic>=0.016, F=3.68).
