Differences between 3M ESPE (Z350 XT, Z350, Z250 and P60) Composites

The Differences between the 3M EPSE products is about the shading, color and mechanical properties ...
So that the indications for the use of each products differs according to those criteria ... for example:

Z350 XT Indications:
- Direct anterior and posterior restorations (including occlusal surfaces)
- Core build-ups
- Splinting
- Indirect restorations (including inlays, onlays and veneers)

Z350 Indications:
- Direct anterior and posterior restorations
- Sandwich technique with glass ionomer resin material
- Cusp buildup
- Core buildup
- Splinting
- Indirect anterior and posterior restorations including inlays, onlays and veneers

Z250 Indications:
- Direct anterior and posterior restorations
- Sandwich technique with glass ionomer resin material
- Cusp buildup
- Core buildup
- Splinting
- Indirect anterior and posterior restorations including inlays, onlays and veneers

P60 Posterior Composite Indications:
- Direct posterior restorations
- Sandwich technique with glass ionomer resin material
- Cusp buildup
- Core buildup
- Splinting
- Indirect posterior restorations including inlays and onlays.

-------------------------------

Choose the Product you want for the certain case you want to treat ...
It's not about filling with composite, actually it's all about with which composite you fill ... !!!

Camphor Mono-Chlorophenol (CMCP)

Solution for Root Canal Disinfection

- Composition:p-Chlorophenol 35%, Camphor 65%

- Properties:PD Camphor Mono-Chlorophenol, also known as CMCP, is an active disinfectant for the treatment of infected root canals & periapical infections.

- Indication:- Disinfection after pulpectomy.
- Treatment of post-traumatic inflammation.
- Pulp dressing.

- How to use:- Dry the root-canal thoroughly.
- Complete the pulpectomy.
- Insert 1 or 2 drops of preparation into the root canal & allow few minutes for it to take effect.
- Remove any excess solution with a cotton pellet or an absorbent paper point.
- Remove gangrenous pulp tissue.
- Use CMCP as a dressing by inserting it into the root canal with a smooth broach.
- Obturate canals temporarily.
- Leave it ‘in situ’ for at least 3 days.
- Make sure the canal is completely disinfected after the period.
- If this is not the case, repeat the dressing before the final obturation.

Cariosolv - Chemo-mechanical Caries Removal

1- CARIDEX

The chemo-mechanical system for caries removal was published in 1975 by HABIB et al.
It is marketed under the trade name of Caridex.
Chemo-mechanical caries removal uses sodium hypochlorite (NaOCl), a non-specific proteolytic
agent (monoaminobutyric acid) removing organic components at room temperature

2- CARISOLV

Carisolv consists of a red gel and transperant fluid.

-----------------------------

Composition:

- Red gel
glutamic acid,
leucin,
lysine,
sodium chloride,
erythrosine,
water and sodium hydroxide

- Transparent fluid
0.5% sodium hypochlorite

-----------------------------

The chemical action of Carisolv is similar to that of Caridex in softening the carious dentin but leaving the healthy dentin unaffected

In caridex it was shown that, NaOCl was dissolving not only necrotic tissue but also sound dentin.

Instruments:
Special instruments designed to scrape in two or in several directions, which reduce the friction during caries excavation

Mechanical Action:
While mixing amino acids react with sodium hypochloride and forms chloromines.
Chloromines seems to involve the chlorination of partially degraded collagen and the conversion of hydroxyproline to pyrrole-2-carboxylic acid, which initiates disruption of altered collagen fibres in carious dentin.

Camphorquinone (CQ)

 - It is a photo-initiator that triggers polymerization of light-curing materials such as dental adhesives and composites.
- CQ does not become a part of the polymer network, suggesting that CQ can be leached out into surrounding environment including dental pulp and exert adversary effects on tissues.
- CQ treatment increases the levels of proinflammatory cytokines (eg, interleukin 6, interleukin 8, and matrix metalloproteinase-3 [MMP3].
- CQ also inhibits odontogenic differentiation and mineralization capacities of DPSC and MC3T3-E1 cells.
- CQ may trigger pulpal inflammation.
- Yellow coloured CQ influences the colour of the composite.
- Amines (Part of the CQ structure) also form by-products during photoreaction and can tend to cause yellow or brownish discolourations under the influence of heat or light.
- The researchers tried to solve the CQ's aesthetics, biocompatibility and toxicity issues, so that they decided to substitute the "simple amines" with polymeric or macromolecular amines.
- CQ can be replaced by polymeric radical photoinitiators carrying the photosensitive CQ groups in the side chain.
- Acylphosphine oxides such as Lucirin TPO are the most common available used commercial products.
