ABSTRACT

Scaling and root planing is one of the most commonly performed procedures in a dental clinic. Most patients will consider the procedure to be causing discomfort or even pain. Intrasulcular topical application of anaesthesia will be preferred over injectable anaesthetic by patients for reduction of pain during scaling and root planing. A double blind split mouth pilot study was designed to find if pain was associated with scaling and root planing and to assess if application of topical anaesthesia reduced the pain. Twenty one patients were enrolled to compare the effect of intrasulcularly applied 20% benzocaine with a placebo in reducing pain during scaling and root planing. Heft Parker Visual analog scale was used to record the level of pain experienced by participants during instrumentation. Independent samples and paired samples t test were used for statistical analysis. There was significant pain associated with scaling and root planing with placebo over baseline (p<0.01). There was significant reduction in pain in benzocaine applied side when compared with placebo (p<0.001). Pain level approached baseline in benzocaine applied side. In this study, pain was effectively and significantly reduced with intrasulcular application of 20% benzocaine in periodontitis patients.

Keywords: Anaesthesia; benzocaine; pain; scaling root planning

ABSTRAK

Penskaleran dan pengetaman akar adalah salah satu prosedur yang paling biasa dilakukan di klinik pergigian. Kebanyakan pesakit akan merasakan bahawa prosedur tersebut adalah kurang menyenangkan atau menyakitkan. Aplikasi bius setempat intrasulkular dijangka lebih digemari oleh pesakit berbanding suntikan anestetik untuk mengurangkan kesakitan semasa pengikisan dan pengetaman akar. Kajian rintis rabun dua belah bagi sebahagian daripada mulut telah direka untuk menentukan sama ada kesakitan adalah dikaitkan dengan penskaleran dan pengetaman akar dan menentukan keberkesanan aplikasi bius setempat dalam mengurangkan kesakitan. Dua puluh satu orang pesakit telah mengambil bahagian bagi membandingkan kesan intrasulkular 20% benzosaine berbanding plasebo dalam mengurangkan kesakitan semasa penskaleran dan pengetaman akar. Skala analog Heft Parker Visual telah digunakan untuk merakam tahap kesakitan yang dialami oleh peserta semasa instrumentasi. Ujian sampel tidak bersandar dan t berpasangan, telah digunakan bagi analisis statistik. Terdapat hubungan yang signifikan bagi kesakitan berkaitan dengan penskaleran dan pengetaman akar di kalangan plasebo pada peringkat dasar (p<0.01). Terdapat pengurangan kesakitan yang ketara di bahagian yang diaplikasi benzosaine berbanding dengan plasebo (p<0.001). Tahap kesakitan menghampiri nilai dasar di sebelah mulut yang diaplikasi dengan benzosaine. Dalam kajian ini, kesakitan telah dapat dikurangkan secara berkesan dan signifikan dengan aplikasi intrasulkular 20% benzosaine dalam kalangan pesakit periodontitis.

Kata kunci: Anestesia; benzosaine; kesakitan; pengetaman akar; penskaleran
