Introduction/Objective. After an orthodontic brackets debonding procedure it is necessary to remove any residual adhesive from the tooth surface, as this is a common cause of enamel damage. The aim of this study is to evaluate the enamel surface after the application of six different methods of adhesive removal following brackets debonding, as well as to compare the duration of these procedures. Methods. For the purpose of this study, 245 human premolars were extracted as part of the orthodontic treatment. Metal brackets were bonded to 210 human premolars with the Aspire adhesive system. After the debonding of brackets, the samples were divided into six groups according to the adhesive removal method applied: tapered fissure tungsten carbide bur, round tungsten carbide bur, composite bur, abrasive disc, adhesive removing pliers, and ultrasonic scaler. Out of 245 premolars, 35 served as a control group. The duration of adhesive removal was recorded. Enamel damages were estimated according to the enamel surface index on the scanning electron microscopy images. Results. Maximum preservation of the enamel surface was accomplished by using a composite bur (1.08). The application of abrasive disc was significantly less time-consuming in comparison to the application of a composite bur (p < 0.01) and an ultrasonic scaler (p < 0.01). Conclusion. The most harmful for the enamel surface was the use of an ultrasonic scaler as well as a round tungsten carbide bur. Adhesive removal done by an abrasive disc thus proved one of the least damaging and the least time-consuming methods.

Kontrol infeksi adalah suatu upaya pencegahan penyebaran mikroorganisme, baik dari pasien ke pasien lainnya, pasien ke operator, operator ke pasien, operator ke lingkungan dan lingkungan ke pasien. Kontrol infeksi yang efektif adalah salah satu indikator penting menunjukkan tercapainya pelaksanaan pelayanan kesehatan gigi dan mulut yang baik. Penelitian ini bertujuan untuk menghitung jumlah koloni dan mengidentifikasi bakteri pada air yang melewati Dental Unit Waterline (DUWL) di dental unit Rumah Sakit Gigi dan Mulut (RSGM) Universitas Andalas. Penelitian ini dilakukan dengan cara menampung air dari high-speed handpiece, water syringe dan ultrasonic scaler. Berdasarkan rumus penelitian Federer (2007) diperoleh sebanyak 9 sampel dalam satu kelompok alat. Sehingga sampel seluruhnya berjumlah 27. Pengambilan sampel didapat menggunakan metode acak sederhana. Hasil penelitian menunjukkan bahwa terdapat 22 sampel air terkontaminasi oleh bakteri, 4 diantaranya tidak sesuai dengan standar ADA. Kontaminasi bakteri kokus Gram positif sebanyak 8 sampel dan basil Gram negatif sebanyak 16 sampel. Bakteri Klebsiella pneumoniae ditemukan pada 2 sampel air yang melalui water syringe. Jadi, dental unit waterline (saluran air) pada dental unit berpotensi sebagai sumber mikroorganisme. Kata Kunci: infeksi, bakteri, waterline, handpiece, syringe

Veterinary dental ultrasonic equipment can cause bacteria to be aerosolized during prophy procedures. Preoperative treatment with clindamycin prior to removal of calculus using an ultrasonic scaler can reduce aerosolized bacteria. Reduction of plaque bacteria was assessed and was statistically significant in those patients receiving clindamycin. This article describes the evaluation and results of clindamycin application when given prior to dental prophy.
