This study aimed to guide the planning of anticurvature filing using pre-determined anatomical points on teeth to establish directions for proper implementation of the technique. Two hundred digital periapical radiographs of human molar teeth were selected and divided into two groups (n = 100): MX (maxillary) and MD (mandibular) molars. Mesiobuccal roots were considered for the MX group and mesial roots for the MD group. Pre-determined anatomical points required for planning the anticurvature filing on the root canal path were located, and the distances between these points obtained. The anticurvature filing was simulated in two different protocols for each group, and the region of dentin removal and the remaining dentin thickness were measured in the safety and danger zones of the root canals. Statistical analysis was carried out at a significance level of 5%. The distances between the anatomical points and the thickness of remaining dentin showed significant differences when the two groups were compared (p < 0.001). No significant differences were found between the two experimental groups regarding the area of dentin removal at the root region, but differences were detected in comparison with dentin removal at the crown (p < 0.001). In terms of wear produced after simulation of both anticurvature filing protocols, significant differences were verified for all regions, except for the dentin remaining at the danger zone. The radiographic location of anatomical points allows for planning and implementation of controlled and efficient anticurvature filing and can be performed in the same manner for maxillary and mandibular molars.

It was concluded that root canal preparation using a rotary instrument design convex triangular cross section produces hygiene apical third of the canal walls of the smear layer significantly compared to manual instruments designed convex triangular cross section and root canal preparation with a rotary instrument design of rectangular cross section produces hygiene apical third of the wall root canal of the smear layer significantly compared convex design of triangular cross section. Key words: hygiene of apical third of root canal wall, smear layer, rectangular cross section rotary instrument, convex triangular cross section rotary instrument ABSTRAKPenelitian ini bertujuan untuk menilai perbedaan kebersihan sepertiga apikal dinding saluran akar dari smear layer antara preparasi yang menggunakan hand use dan rotary instrument design convex triangular cross section dengan rotary instrument design rectangular cross section. Sampel gigi premolar rahang bawah yang memenuhi kriteria inklusi dibagi 3 kelompok, masing-masing sebanyak 10 sampel, lalu dipreparasi dengan menggunakan instrumen hand use design convex triangularcross section, rotary instrument design convextriangularcross section, danrotary instrument design rectangular cross section. Setelah dipreparasi, sampel dikeringkan, gigi dibelah dua menggunakan stainless steel chisel. Salah satu belahan gigi dipilih secara acak,kemudian diamati dengan SEM (pembesaran 1000x).Hasil penelitian menunjukkan bahwa kelompok hand use instrument mempunyai persentase kebersihan smear layer yang paling rendah, sedangkan kelompok rotary instrument rectangular cross section memiliki persentase yang paling tinggi.Disimpulkan bahwa preparasi saluran akar menggunakan rotary instrument design convex triangular cross section menghasilkan kebersihan sepertiga apikal dinding saluran akar dari smear layer secara signifikan dibandingkan manual instrument design convex triangular cross section dan preparasi saluran akar dengan menggunakan rotary instrumentdesain rectangular cross section menghasilkan kebersihan sepertigaapikal dinding saluran akar dari smear layer secara signifikan dibandingkan desain convex triangular cross section. Kata kunci: kebersihan sepertiga apikal dinding saluran akar, smear layer, rectangular cross section rotary instrument, convex triangular cross section rotary instrument Koresponden: Nurni Amda, Jl.
