The central dogma doesn't really cover the form of RNA that is speculated to be repaired here: ribosomal RNA.
The central dogma concerns mainly the transcription of DNA to mRNA, the reverse transcription of RNA back to DNA, and the translation of mRNA to protein. But over time RNA has turned up in a wide range of other activities. In this case, ribosomal RNA is the functional heart of the ribosome- the machine that translates mRNA to protein.
Ribosomal RNA represents a very significant investment of resources for the cell and so if it gets damaged, the cell won't be able to make proteins as quickly, or the proteins that get made might have errors, both of which have dire effects on the cell.
