Based on the instrumentation system used, all the patients were allocated randomly into three groups (&lt;i&gt;n&lt;/i&gt; = 28): Group I: Reciprocating file no 1-ONE RECI, group II: Reciprocating file no 2-E3 AZURE, and Group III: Continuous rotary file-HERO GOLD, respectively. Patients were directed to score their degree of postoperative pain utilizing a visual analog scale after 12, 24, 48, and 72 hours. Additionally, patients were directed to note the analgesic consumption during the aforementioned time. Clinical and radiological assessments of the patients were carried out after 1, 3, and 6 months.

{"title":"Effect of Axial Wall Height on Bacterial Adhesion, Marginal Seal, and Color Change of One-piece Molar Zirconia Endocrown.","authors":"Mohammed Y Tarrosh","doi":"10.5005/jp-journals-10024-3834","DOIUrl":"https://doi.org/10.5005/jp-journals-10024-3834","url":null,"abstract":"<p><strong>Aim: </strong>This study investigates the effect of various preparation designs influence the bacterial adhesion, vertical discrepancy, and mean color change (Δ<i>E</i>*), of maxillary and mandibular one-piece zirconia endocrowns cemented to molar teeth.</p><p><strong>Materials and methods: </strong>Forty extracted human maxillary and mandibular molars (<i>n</i> = 20 each) were divided into two groups based on the remaining all surfaces axial height as group with 2 mm and group with 4 mm. <i>Streptococcus mutans</i> adhesion was evaluated using Mueller-Hinton agar plates, and vertical discrepancies of the cemented endocrowns were assessed by a digital microscope. The specimens were stained using Saudi coffee, then the color parameters were measured using a spectrophotometer before and after immersion of the samples. Data were analyzed using SPSS to assess significance between and within groups, where a <i>p</i>-value of ≤ 0.05 indicated statistical significance.</p><p><strong>Results: </strong>Colony-forming units were between 489 ± 4.912 and 518 ± 6.667 (CFU/mm²) for both one-piece endocrown groups with no significant difference. Marginal discrepancy values were the highest with 2 mm axial wall in mandibular molars (44.30 ± 2.73 µm) and the lowest with 2 mm axial wall in maxillary molars (4.75 ± 0.85), with a significant difference (<i>p</i> < 0.05). The mean Δ<i>E</i>* values for one-piece endocrown for maxillary molars at 2 mm axial wall were the highest at 7.18 ± 1.16, followed closely by 4 mm axial wall in maxillary molars at 7.10 ± 0.61. In mandibular molars with 4 mm axial wall, the Δ<i>E</i>* was 2.51 ± 0.32, and the difference was significant (<i>p</i> < 0.001).</p><p><strong>Conclusion: </strong>The one-piece endocrown with the used axial wall height did not significantly affect the bacterial adhesion. The Δ<i>E*</i> values were slightly high but still within clinically acceptable ranges for both groups with maxillary molars exhibited higher Δ<i>E</i>*, particularly with 2 mm height group. Marginal discrepancy values were within the recommended range for both groups.</p><p><strong>Clinical significance: </strong>Using a one-piece endocrown restoration after endodontic treatment may minimize the bacterial adhesion and provide a good coronal seal. So, endocrowns can be a good option for posterior maxillary and mandibular molar teeth with remaining 2-4 mm axial height. How to cite this article: Tarrosh MY.
