SU1355235A1 - Method of diagnosis of caries under crown - Google Patents

Abstract

To determine the localization of caries, the current along the tooth-filling border is measured, and at a current of 3–10 µA, caries is diagnosed on the cavity walls, and at 11–15 µA, at the bottom of the cavity.

Description

The invention relates to medicine, namely to dentistry.

The aim of the invention is to determine the localization of caries and prevent the development of secondary caries.

Example 1, B. patient, born in 1971, turned to a dentist

no gap between the filling and the tooth wall was detected. Electrometry readings at the distal border of the tooth-seal 15.0 µA. After removal of the cavity, softened dentin was found on the walls and bottom of the carious cavity.

Conducted. Studies have shown

To carry out a topical diagnosis of caries is accurate, allowing in clinical conditions to recognize in a few seconds a pathological process that cannot be determined by known methods, and decide on the extent of treatment: to remove the entire filling or partially in the area of localization.

Claims (2)

Invention Formula for the purpose of rehabilitation. There was no complaint about Q1 tooth pain — the proposed diagnostic method did not present. A year and a half ago, tooth decay under the filling allows back a tooth to be treated for average caries. Objectively: on the chewing surface there is a medium size silicide seal, smooth when probing, not changed in color. The electric current readings at the border of the tooth-filling (medial border) is 8.0 µA, which indicates the presence of a carious process under the filling on the walls of the cavity. After the filling was removed, softened dentin was found on the walls of the cavity, the bottom was clean and dense. Example 2. Patient Bl, born 1971, turned to a dentist for the purpose of rehabilitation. The patient had no complaints. 2 years 4 months ago, GB tooth was treated for average caries. Objectively: on the chewing surface there is a medium size sidilond filling, it was noted that the filling material was killed (disintegration), the filling was not changed in color, it was rough when measuring the caries under the filling by applying electrolyte to the test tooth and then measuring the current value that , in order to determine the localization of caries and prevent the development of secondary caries, current values along the border, tooth-filling are measured and at current values of 3.0-10.0 µA, caries is diagnosed on the walls when the value is 11.0-15.0 μA - at the bottom of the cavity. thirty Spruce up M.
