Summary
Mineral trioxide aggregate (MTA) and Portland cement both effectively treat periradicular lesions after endodontic surgery. Both materials demonstrated successful periradicular tissue regeneration and bone formation in clinical and CT assessments.
Area of Science:
- Endodontics
- Dental Materials Science
- Oral Surgery
Background:
- Periradicular lesions often require endodontic surgery for treatment.
- Root-end filling materials play a critical role in the success of endodontic surgery.
- Mineral trioxide aggregate (MTA) and Portland cement are commonly used materials in endodontic procedures.
Purpose of the Study:
- To compare the clinical and computed tomography (CT) outcomes of endodontic surgery using Portland cement versus MTA as root-end filling materials.
- To evaluate the efficacy of Portland cement and MTA in treating periradicular lesions.
Main Methods:
- Three patients with periradicular lesions underwent endodontic surgery with root-end fillings.
- Materials used included mineral trioxide aggregate (MTA) and Portland cement.
- Clinical and CT assessments were performed six months post-surgery.
Main Results:
- Periradicular tissue regeneration was observed in all treated cases.
- No significant differences in bone formation were noted between MTA and Portland cement groups.
- Both materials demonstrated comparable outcomes in healing periradicular lesions.
Conclusions:
- Both mineral trioxide aggregate (MTA) and Portland cement are successful root-end filling materials for treating periradicular lesions.
- The study suggests comparable efficacy between MTA and Portland cement in promoting periradicular healing.

01:21Portland Cement
1.5K
Portland cement is the essential binding ingredient in concrete, made from finely ground materials including lime, iron, silica, and alumina. Lime is derived primarily from limestone, marble, marl, seashells, and clays, which also supply iron and alumina, while silica is sourced from sand, chalk, and bauxite. Contemporary manufacturing of Portland cement is a significant source of carbon dioxide emissions, prompting research into reducing its content in concrete through alternative...

01:29Additives and Fillers in Concrete
453
Additives and fillers are integral to enhancing the properties of concrete. Pozzolans and blast-furnace slag are additives or admixtures due to their reactions with calcium hydroxide released during cement hydration. Fillers, which are finely ground and similar in fineness to Portland cement, improve concrete attributes such as workability density, and reduce capillary bleeding or cracking. Some fillers possess hydraulic properties or participate in benign reactions within the cement paste.

01:21Pozzolans
782
Pozzolans are siliceous or aluminous materials blended with Portland cement. They interact with the calcium hydroxide produced during the hydration of Portland cement and contribute to improved strength and durability of concrete. The pozzolanic activity, a measure of a pozzolan's effectiveness, is typically assessed using the strength activity index, as defined in ASTM C 618-93, which calculates the ratio of the compressive strength of cement mixtures with and without pozzolan.

Portland blast-furnace cement is made by blending Portland cement clinker with granulated blast-furnace slag, which accounts for 25 to 65 percent of the cement's weight. Despite its similarities to ordinary Portland (Type I) cement in terms of fineness and setting times, its early strength is lower, though it achieves comparable strength later on. It's particularly suited for mass concrete structures and marine environments due to its lower heat of hydration and superior sulfate...

820
Mortar, a mixture of Portland cement, hydrated lime, sand, and water, is a crucial binding material in construction. Its primary function is to join masonry units together, filling gaps and ensuring a uniform distribution of weight across the structure. This helps in preventing potential weaknesses. Mortar also serves as a protective barrier against environmental elements such as water and wind, thereby safeguarding the interior of the structure. It also compensates for surface irregularities...

01:18Porosity in Cement Paste
592
The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.
