Dentine caries excavation: a review of current clinical techniques

Since the invention and application of rotary instruments, the operative treatment of carious lesions has often resulted in considerable removal of tooth structure. More recently, newer techniques for removal of carious dentine have been developed in an attempt to minimise this excessive tissue loss. The following article reviews and discusses some of the techniques available to excavate demineralised dentine clinically. These methods can be classified as mechanical and non-mechanical, rotary and non-rotary and include: dental handpieces/burs, manual excavators, air-abrasion, air-polishing, ultrasonication, sono-abrasion, chemo-mechanical methods, lasers and enzymes. The advantages and disadvantages of each technique are discussed.

PENDEKATAN PREVENTIF DALAM MENANGGULANGI KARIES

Treatment of caries lesions has been shifted to a preventive approach and the recommended measures by the WHO are clinical and radiological examination to detect early lesions and cavities, evaluation of caries risk factors, management of these factors, treatment of caries lesions and formulation of maintenance program. The how and why of this preventive approach will be briefly viewed.

Pemanfaatan Saliva dalam Mendeteksi Faktor-Faktor Resiko terhadap Karies

Salia can be used to detect several diseases including caries. In conservative dentistry, examinations of saliva to risk factors for caries has been developed. This is partly due to the fact that treatment of caries lesions has been shifted to a preventive approach. Examinations of salivary flow, buffer capacity and laboratory tests for Lactobacillus and Streptococcus mutans will be reviewed.

Scanning electron microscopic analysis of diseased and healthy dental hard tissues after Er:YAG laser irradiation: In vitro study

The aim of this study was to treat carious lesions, sound dentin, and enamel either with conventional methods or with an Er:YAG laser and to compare the results. Thirty freshly extracted carious human teeth were divided into two groups. In the first group, lesions were treated with burs in a dental handpiece; in the second group, we used the Er:YAG laser with parameters recommended by the manufacturer (Kavo). After treatment, the teeth were prepared for scanning electron microscopic observation. On laser-treated teeth, scaly, flaky, rough surfaces were seen: surfaces were clean with several morphological reliefs that may enhance bonding resin restoration. The Er:YAG laser beam can ablate carious dentin with an energy level of 250 mJ at 2 Hz. Sound dentin can be cut at 300 mJ and 2 Hz; for enamel, 350 mJ and 3 Hz are required. The Er:YAG laser seems to be effective in the treatment of carious lesions and in cavity preparation in vitro.

Visualization of stannous fluoride treatment of carious lesions by subtraction radiography

To determine whether treatment with SnF 2 results in changes in radiographic density, eight extracted teeth with lesions confined to the enamel and five with lesions extending into the dentin were radiographed before and after treatment with a 10% SnF 2 solution. Although visual comparison of pretreatment and post-treatment radiographs showed increased density in some areas where the pretreatment radiographs had shown demineralization and unchanged conditions in other instances, subtraction images of these radiographs revealed density increase in all the demineralized areas. Even in cases with white spot lesion not visible on radiographs, the subtraction images disclosed an increase in radiographic density.

Use of Sealants in the Prevention and Early Treatment of Carious Lesions: Cost Analysis

Placing sealants over carious as well as noncarious occlusal surfaces can be safe and effective. Selective placement of sealants on teeth of patients who show early evidence of caries activity can improve the cost-effectiveness of the procedure.

Spread of carious lesions in dentin

The nature and characteristics of carious dentin have generated much controversy regarding its final disposition in cavity preparation. The author presents additional information concerning the treatment of carious lesions.
