| The structural changes and morphological derivatives of progressive dentin hypermineralization determine the bonding to its surface. A planimetric study and fracture volume estimate were conducted to assess the efficacy of resin composite bonded to hypermineralized cervical dentin with and without retentions by applying a shear test. Thirty-four premolars from adult patients were used to obtain a flat cervical dentin surface. The specimens were distributed randomly into two groups: 1) experimental, where hemispherical retentions were carved into the cervical dentin, and 2) control, where the flat dentin was maintained. Using a jig, a resin column was built into the dentin surface fitted with bonding in specimens from both groups, which were then subjected... |

| Financal assurance rules, also known as financial responsibility or bonding requirements, foster cost internalization by requiring potential polluters to demonstrate the financial resources necessary to compensate for environmental damage that may arise in the future. Accordingly, assurance is an important complement to liability rules, restoration obligations, and other regulatory compliance requirements. The paper reviews the need for assurance, given the prevalence of abandoned environmental obligations, and assesses the implementation of assurance rules in the United States. From the standpoint of both legal effectiveness and economic efficiency, assurance rules can be improved. On the whole, however, cost recovery, deterrence, and enforcement are... |
