Complications of interproximal enamel reduction are hypersensitivity , irreversible damage of dental pulp , increased formation of plaque , the risk of caries in the stripped enamel areas and periodontal diseases .
CONCLUSION Interproximal enamel reduction is an important part of orthodontic treatment for gaining space in the dental arch , and for the correction of the Bolton index discrepancy
OBJECTIVE Interproximal enamel reduction is a part of orthodontic treatment for gaining a modest amount of space in the treatment of crowding .
Today interproximal enamel reduction has become a viable alternative to the extraction of permanent teeth , and helps to adjust the Bolton Index discrepancy .
The aim of the study is to evaluate various interproximal enamel reduction techniques , its indications , contraindications and complications presented in recent scientific studies .
Effects of extraction and nonextraction therapy with air-rotor stripping on facial esthetics in postadolescent borderline patients.
INTRODUCTION A prospect i ve r and omized study was design ed to compare the skeletal , dental , and soft-tissue profile changes in Class I borderline patients treated with extraction and non extraction  by means of the air-rotor stripping ( ARS ) technique and to compare the treatment times . METHODS Twenty-six borderline patients with balanced and orthognathic facial profiles were r and omly divided into 2 groups . In the first group , 13 subjects with a mean age of 18.1 + /- 3.7 years and mean maxillary and m and ibular crowding of 5.7 + /- 1.5 and 5.9 + /- 1.4 mm , respectively , were treated by removal of 4 premolars with minimum anchorage . In the second group , 13 subjects with a mean age of 17.8 + /- 2.4 years and mean maxillary and m and ibular crowding of 5.0 + /- 1.3 and 5.9 + /- 1.3 mm , respectively , were treated with ARS .  Lateral cephalometric radiographs and dental models taken before and after treatment were evaluated . RESULTS The initial skeletal , dental , and profile characteristics of both groups were similar . In the first group , the maxillary and m and ibular incisors were slightly retracted , whereas lip positions did not change . In the non extraction group , maintenance of maxillary incisor position , slight protrusion of the m and ibular incisors and the upper and lower lips were observed at the end of treatment . The nasolabial angle decreased significantly . Because of postpubertal growth of the nose and the chin , the lips appeared slightly retrusive after extraction therapy , whereas lip protrusion was compensated in the non extraction group . The main soft-tissue profile differences between the 2 groups were 1 to 1.5 mm more retruded upper and lower lip positions in the extraction patients , but both groups had well-balanced and desirable facial esthetics with all profile measurements within normal limits . Non extraction therapy with ARS reduced treatment time by 8 months . CONCLUSIONS Both extraction and ARS combined with non extraction therapies are effective treatment alternatives for Class I borderline patients with good facial profile and moderate dental crowding
