140 human molar crowns were used after separating them from their root

140 human molar crowns were used after separating them from their roots at the cementoenamel junction with a water-cooled, low-speed diamond saw (Mecatome T201 A, Presi, Grenoble, France). The roots were discarded, and the crowns were randomly assigned into two groups: 70 samples for testing bond strength to enamel, and 70 for evaluating adhesion to dentin. To prepare enamel surfaces, a 0.5 mm-deep flat area was created in the center of the buccal surface of each crown using the cutting machine mentioned above. Each crown was then embedded in acrylic resin blocks (Acropars, Marlic Medical Industries Co., Tehran, Iran), positioning the buccal surface facing upward and level with the base. The enamel was polished gently with 320-grit silicon carbide abrasive paper (Starcke GmbH & Co. KG, Melle, Germany) to ensure surface uniformity. Enamel quality and flatness were examined using a stereomicroscope (Stemi 305, Carl Zeiss AG, Oberkochen, Germany). For the dentin group, the occlusal enamel and superficial dentin layers were removed to expose flat mid-coronal dentin using the same saw, under continuous water cooling. The dentin surfaces were also embedded in acrylic blocks with the surface aligned parallel to the base. A smear layer was created by polishing the exposed dentin for 60 s with 320-grit silicon carbide paper. Finally, the surfaces were rinsed and lightly dried using an air–water spray syringe (DABI Atlante, São Paulo, Brazil). Before bonding the RMGIC to the prepared enamel and dentin surfaces, a conditioning step was performed using GC Cavity Conditioner (GC Corporation, Tokyo, Japan) in accordance with the manufacturer's guidelines. The conditioner was applied to the tooth surface using a cotton pellet or applicator sponge. It was allowed to react for 10 s, after which the surface was thoroughly rinsed with water and gently blotted dry, leaving the surface moist but not desiccated. generate a image for this matter

Scientific dental research illustration showing the step-by-step laboratory preparation of human molar crowns for bond strength testing. The image shows: 1) A human molar tooth being cut at the cementoenamel junction with a water-cooled diamond saw, separating the crown from the root. 2) Two groups of crown samples - one group for enamel testing showing a flat 0.5mm buccal enamel surface, and one group for dentin testing with occlusal enamel removed to expose mid-coronal dentin. 3) Each crown embedded in a clear acrylic resin block with the prepared surface facing upward. 4) Polishing of the surface with silicon carbide abrasive paper to create a uniform smear layer. 5) Application of GC Cavity Conditioner with a cotton pellet for 10 seconds, followed by rinsing and blotting dry. The style is a clean, labeled scientific diagram with anatomical cross-sections, showing enamel (white), dentin (pale yellow), and acrylic resin blocks (transparent). Labels and arrows indicate each step clearly.

Here is a scientific illustration depicting the key stages of your specimen preparation protocol:

Dental bond strength specimen preparation

The image covers the main procedural steps described in your methodology:

Crown separation at the cementoenamel junction using the water-cooled diamond saw, with roots discarded
Group division into enamel (flat 0.5 mm buccal surface) and dentin (occlusal enamel removed to expose mid-coronal dentin) subgroups
Acrylic resin embedding with the prepared surface aligned flush with the block base
Surface polishing with 320-grit silicon carbide paper to standardize the smear layer
Cavity conditioner application with a cotton pellet for 10 s, followed by rinsing and moist blot-drying before RMGIC bonding

give me the methodology in step wise

Here is the methodology broken down into clear, sequential steps:

Step-by-Step Methodology

Phase 1: Sample Collection & Crown Separation

Step 1 - Tooth Collection

Collect 140 human molar teeth for the study.

Step 2 - Crown Separation

Separate each crown from its root at the cementoenamel junction (CEJ).
Use a water-cooled, low-speed diamond saw (Mecatome T201 A, Presi, Grenoble, France).
Discard all roots; retain only the crowns.

Phase 2: Random Group Assignment

Step 3 - Group Division

Randomly assign the 140 crowns into two equal groups:
- Group A (n = 70): Bond strength testing on enamel
- Group B (n = 70): Bond strength testing on dentin

Phase 3: Enamel Surface Preparation (Group A)

Step 4 - Flat Surface Creation

Using the same low-speed diamond saw, create a 0.5 mm-deep flat area at the center of the buccal surface of each crown.

Step 5 - Embedding in Acrylic Resin

Embed each crown in an acrylic resin block (Acropars, Marlic Medical Industries Co., Tehran, Iran).
Position the buccal surface facing upward and level with the block base.

Step 6 - Surface Polishing

Gently polish the enamel surface with 320-grit silicon carbide abrasive paper (Starcke GmbH & Co. KG, Melle, Germany) to achieve surface uniformity.

Step 7 - Quality Check

Inspect enamel quality and flatness under a stereomicroscope (Stemi 305, Carl Zeiss AG, Oberkochen, Germany).

Phase 4: Dentin Surface Preparation (Group B)

Step 8 - Dentin Exposure

Remove the occlusal enamel and superficial dentin layers using the same water-cooled diamond saw to expose a flat mid-coronal dentin surface.

Step 9 - Embedding in Acrylic Resin

Embed each crown in an acrylic resin block with the dentin surface positioned parallel to the block base.

Step 10 - Smear Layer Creation

Polish the exposed dentin surface for 60 seconds using 320-grit silicon carbide paper to create a standardized smear layer.

Step 11 - Surface Rinsing & Drying

Rinse the surface and lightly dry it using an air-water spray syringe (DABI Atlante, São Paulo, Brazil).
Leave the surface moist, not desiccated.

Phase 5: Surface Conditioning (Both Groups)

Step 12 - Conditioner Application

Apply GC Cavity Conditioner (GC Corporation, Tokyo, Japan) to the prepared surface using a cotton pellet or applicator sponge, following the manufacturer's guidelines.

Step 13 - Reaction Time

Allow the conditioner to react on the surface for 10 seconds.

Step 14 - Rinsing

Thoroughly rinse the surface with water to remove the conditioner.

Step 15 - Blot Drying

Gently blot the surface dry, ensuring it remains moist but not desiccated - ready for RMGIC bonding.

Summary Table

Step	Action	Group
1-2	Crown separation at CEJ	Both
3	Random group assignment (70 + 70)	Both
4-7	Enamel flat surface prep, embedding, polishing, QC	Group A
8-11	Dentin exposure, embedding, smear layer, drying	Group B
12-15	Cavity conditioner application and surface prep	Both

A clean, professional scientific flowchart on a white background showing the methodology for dental bond strength testing. The flowchart uses rectangular boxes for process steps, diamond shapes for decisions/splits, and arrows connecting each step. The flow is as follows: START (oval) -> "140 Human Molar Crowns Collected" -> "Crown Separation at CEJ using Water-Cooled Low-Speed Diamond Saw (Mecatome T201A)" -> "Roots Discarded | Crowns Retained" -> "Random Assignment into 2 Groups" Then splits into TWO parallel branches: LEFT BRANCH (light blue boxes) labeled "GROUP A - ENAMEL (n=70)": -> "Create 0.5mm Flat Area on Buccal Surface" -> "Embed in Acrylic Resin Block (Buccal Surface Facing Up)" -> "Polish with 320-grit SiC Abrasive Paper" -> "Inspect Surface Quality under Stereomicroscope" RIGHT BRANCH (light green boxes) labeled "GROUP B - DENTIN (n=70)": -> "Remove Occlusal Enamel & Superficial Dentin" -> "Embed in Acrylic Resin Block (Surface Parallel to Base)" -> "Polish with 320-grit SiC Paper for 60 seconds (Smear Layer)" -> "Rinse & Lightly Air-Dry (Moist, Not Desiccated)" Both branches MERGE back into a single flow (yellow boxes): -> "Apply GC Cavity Conditioner with Cotton Pellet" -> "Allow to React for 10 Seconds" -> "Rinse Thoroughly with Water" -> "Blot Dry (Surface Moist, Not Desiccated)" -> END oval "Surfaces Ready for RMGIC Bonding" The chart is well-spaced, uses bold clear font labels, colored arrows, and a legend. Title at top: "Methodology Flowchart: Bond Strength Testing of RMGIC to Enamel and Dentin"

The flowchart illustrates the complete methodology with:

Top section - Common initial steps: crown collection, CEJ separation, and random group assignment
Left branch (blue) - Group A enamel preparation pathway (n = 70)
Right branch (green) - Group B dentin preparation pathway (n = 70)
Bottom merge (yellow) - Shared conditioning steps applied to both groups before RMGIC bonding

Incorporating ZnO and mesoporous ZnO NPs in RMGIC image

Generating Image

Scientific research illustration showing the incorporation of ZnO nanoparticles and mesoporous ZnO nanoparticles into Resin-Modified Glass Ionomer Cement (RMGIC). The image shows a detailed step-by-step process: 1. On the left: Two types of nanoparticles side by side - conventional ZnO nanoparticles (solid, spherical, white crystalline hexagonal particles labeled "ZnO NPs") and mesoporous ZnO nanoparticles (porous, sponge-like spherical particles with visible internal pores labeled "Mesoporous ZnO NPs"), with a magnified inset showing the porous internal structure. 2. In the center: A mixing/incorporation diagram showing the nanoparticles being weighed on a microbalance and added in specific weight percentages (0%, 1%, 2%, 3% wt) into the RMGIC powder component. Arrows show the blending process with a spatula on a mixing pad. 3. On the right: The final RMGIC material - showing the mixed cement paste being applied to a tooth cross-section (enamel and dentin layers visible), with the nanoparticles uniformly distributed within the cement matrix shown in a magnified inset. The background is clean white. Color coding: ZnO NPs in white/grey, mesoporous ZnO NPs in light blue with pores highlighted, RMGIC cement in translucent cream/yellow. Include clear labels, scale bars, and arrows. Title at top: "Incorporation of ZnO NPs and Mesoporous ZnO NPs into RMGIC". Professional scientific diagram style.
