Resorption however rarely compromises the longevity of the teeth.22 Vertical loss of bone through periodontal disease creates a far greater loss of attachment and support than its equivalent loss around the apex of a tooth.
Loss of attachment was documented in no cases from the control, i.e. non-extractive, group.
Inflammation and loss of attachment around dental implants (i.e. peri-implantitis) has become a growing concern within the field of dental implantology [1 7].
Recession is of concern to patients who view the loss of attachment as a health issue as well as an esthetic problem.
Various studies have noted a greater loss of attachment in treated (with or without extraction) with respect to untreated patients [2, 3, 33].
The loss of attachment might be due to an imbalanced shear force caused by the uneven evaporation of solvent during the dehydration process.
The mean loss of attachment in our study group (the distance from the CEJ to the base of the defect) was 0.9 mm in the teeth adjacent to the extraction site.
Nevertheless, it is recognized that a loss of attachment can occur when the distance between the CEJ and the bone is greater than the mean values in the periodontally healthy population (i.e. when it is greater than 2 mm) [31, 32].
Even though, on average, the distances between the CEJ and the defect base and between the CEJ and the bone peak are under the critical 2 mm in the study group, when these were greater than 2 mm, loss of attachment did occur at the sites under investigation, i.e. around 20% of cases.
The grief response, especially of the youngest children, provided clear evidence of loss of attachment to childcare givers and their supervisors, including Anna Freud.
However, DR5 is involved in mediating anoikis, a form of apoptosis triggered by loss of attachment of cells from the extracellular matrix [36], [37].
