Gaj et al concluded that the use of anal self-massage with a finger appears to induce a better resolution of acute anal fissure than anal dilators and in a shorter time [1]. We have objections to this strategy, because anal manipulation in the traumatized area of the fissure can induce further injury and aggravate symptoms, exposing the patient to the risk of fistula or abscess formation. Anal ...

objective: long-term retention of pit and fissure sealants is crucial for their success. this clinical study evaluated the retention rate of a flowable composite resin (filtek supreme xt flowable restorative) compared to a conventional resin-based sealant (concise light cure white sealant) over 12 months. materials and methods: forty subjects aged 6 to 9 years were included in the study. using ...
