AccuBoost is a technique for whole breast irradiation that is designed to target and deliver a boost dose accurately and reliably to the lumpectomy cavity margin.
4 More recently, separate cavity margin sampling at the time of initial lumpectomy has been used to reduce the number of reexcisions for positive lumpectomy margins.
4,5) Institutions practicing separate cavity margin sampling at the time of initial breast lumpectomy have a higher incidence of positive margins (82%) in the initial lumpectomy before cavity margin sampling is performed.

Combining the traditional technique of cavity margin refinishing, acid etching of the enamel and the dentine with the laser preparation technique, the advantages of both techniques can be employed.
Cavity margins that are less finished compared to traditional mechanical techniques,
The principle disadvantage of the laser technique in terms of microleakage and thus of adhesion at the enamel margins can be avoided with a mechanical finishing of the cavity margins, with manual, rotative or ultrasonic instruments followed by etching with 35-37% orthophosphoric acid.
Cavity margins were re-excised at the same procedure and a second specimen with new orientations was sent for permanent sections.
