- Bioceramics are materials which include Alumina, Zirconia, Bioactive glass, Glass ceramics, Hydroxyapatite, resorbable Calcium phosphates.
Used in dentistry for
Filling up bony defects
Root repair materials
Apical fill materials
Aids in regeneration etc.
Bioinert: non-interactive with biological systems (Alumina, zirconia)
Bioactive: durable tissues that can undergo interfacial interactions with surrounding tissue (bioactive glasses, bioactive glass ceramics, hydroxyapatite, calcium silicates)
Biodegradable: soluble or resorbable, eventually replaced or incorporated into tissue (Tricalcium phosphate, Bioactive glasses).

Bioceramic-Based Root Canal Sealers
The main functions of root canal sealers are to seal off the
voids, form a bond between the core of the filling material
and the root canal wall, and act as a lubricant. Sealers have
been classified according to chemical composition as zinc
oxide eugenol, calcium hydroxide, glass ionomer, silicone,
resin, and bioceramic-based sealers.

Properties
Biocompatibility
Bioceramic-based root canal sealers are biocompatible
which is mainly due to the presence of calcium phosphate
in the sealer.
Flow
Flow of a sealer allows it to fill canals, isthmus, accessory
canals, and voids between the master and accessory cones.
According to ISO 6786/2001, a root canal sealer should have
a flow rate of not 20 mm. Bioceramic-based sealers meet
the ISO requirements of flow.
Retreatability
Bioceramic sealers are difficult to remove from the root
canals during retreatment and post-space preparation.
Solubility
iRoot SP and MTA-Fillapex are highly soluble and do
not meet ANSI/ADA requirements. MTA-Angelus has
low solubility which is consistent with ANSI/ADA
requirements
Radiopacity
Bioceramic sealers are radiopaque due to presence of bismuth trioxide and barium sulfate.
Antimicrobial Properties
Bioceramic sealers are antimicrobial in nature due to their
alkalinity and release of calcium ions which stimulates
repair by the deposition of mineralized tissue.
Adhesion
Sealing ability of bioceramic-based sealers is because of
following three mechanisms:
1. Diffusion of the sealer particles into the dentinal
tubules and form mechanical interlocking bonds
2. Infiltration of sealer’s mineral content into intertubular
dentin forming mineral infiltration zone, produced
after denaturing the collagen fibers with a strong alkaline sealer
3. Reaction of phosphate with calcium silicate hydrogel
and calcium hydroxide, produced by reaction of calcium silicates in the presence of dentin’s moisture,
resulting in the formation of hydroxyapatite along the
mineral infiltration zone.
Conclusion
When compared to conventional materials used in
endodontic treatments, bioceramic cements are not
only biocompatible but also bioactive as they proved to
be involved in controlling the tissue healing and pulp
regeneration. Seeing the advantages of bioceramics,
recent studies favor bioceramic materials even if not many
products are available for use. Being biocompatible and
bioactive materials, these are used in root perforations,
large apical foramens, and root resorptions. MTA or
MTA-like cements have been used as materials of choice
in regenerative endodontics, vital pulp therapy, and periradicular surgery due to their clinical success rate. Based
on in-progress technology of fabrication, it is expected
that the newer bioceramic cements will overcome drawbacks of previous ones, mainly the discoloration problem.
With further research, bioceramics has the potential to
become the preferred materials for the various endodontic procedures.

Very informative thank you
So nice of you :)
الله يبارك فيك ❤
وفيكِ يا رب 🌷🌷
ممكن باقي المحاضرة؟
شرح ممتاز🙏🙏🙏🙏
لو حبيت اعمل post هيبقي في صعوبه وانا نازل بgate ?
دكتور لو سمحت بعد ما تقطع الكوتابيركا، نستخدم plugger بارد او لازم يكون ساخن؟
لا plugger بارد عشان نعمل compaction
يعني مش هيسبب اي الم لو في sealer puff
Can the Sealer puff near to the mental foramen or IANC cause numbness?
بيتوقف الامر علي المسافه ممكن نعمل cbct ونشوف السبب
بالنسبة لتمنه ؟
قبل ارتفاع الدولار ولا بعد ؟؟ 😂
متي اعمل post
في حاله فقد السنه ل50% او اكتر من ال crown سواء بسبب التسوس او كان undermined enamel
Puff يا دكتور ماتعمل مشاكل
The "sealer puff" result from endodontic obturation is generally considered to be a good outcome. The "sealer puff" is a term used to describe the expansion of the sealer material that occurs when it is heated and pressurized during the obturation process. This expansion helps to create a more complete and secure seal within the root canal system, which can help to prevent leakage and the re-contamination of the root canal space. A "sealer puff" result indicates that the sealer material has expanded as intended and has adequately filled the root canal space. However, it is important to note that the success of the obturation procedure is dependent on a number of factors, including the proper preparation of the root canal space, the selection of appropriate materials, and the skill and expertise of the practitioner.
