Dental erosion is defined as the loss of tooth substance by a chemical process that does not involve bacterial action.1 Thus erosion encompasses different chronic destructive processes (excluding dental caries) affecting the teeth that lead to an irreversible loss of tooth structure.
Erosion was reported as early as in the 19th century and since then the incidence and prevalence of dental erosion has been increasing.6 Especially with the decline in dental caries in developed countries, erosion is now becoming a focus of increasing interest both in clinical dentistry and research.
Excision, she said, is her preferred approach to management of vaginal mesh erosion
, and it can generally be performed in the office.
If cavitation erosion
was observed long time ago, the firs technical cases (ship propellers and hydraulic turbine runners) eroded by cavitation phenomena, were noticed about 1890 (Bordeasu 1997).
The extent of erosion
was limited, grade A in about 34%, grade B in 41%, grade C in 9%, and the most extensive erosion
, grade D, in about 2% of patients, reported Dr.
The nasal alae were intact bilaterally, but erosion
of the columellar skin was evident (figure 1).
The rationale of this study was to find out correlation between dental erosion
and its impact on different age groups.
There were no erosions
in 37 women who underwent concurrent supracervical hysterectomy or in 35 women who had a previous total abdominal hysterectomy and then underwent sacral suspension alone, said Dr.
Reversing effects of desertification requires (1) quantitatively understanding mechanisms governing soil erosion
, (2) identifying root causes of land degradation, (3) predicting the amount and distribution of soil loss in relation to possible causal factors, and (4) making erosion
assessment for conservation policy-making (Heimlich and Bills 1984; Perrens and Trustrum 1985).
experiments in the field where no electric power is available, an automated device for runoff and soil loss measurements was designed.
