EndodonticsApicectomy specifically refers to the surgical removal of the root tip (apex) of an endodontically treated tooth, typically 3mm of the root end, to eliminate persistent infection.

EndodonticsRadiographic evidence of bone filling in periapical lesions typically becomes apparent 8-12 months after successful endodontic treatment. Earlier time frames show soft tissue healing, while complete bone regeneration requires this longer period.

Conservative DentistryGingivally, the depth of a class V cavity is typically 0.75-1 mm. This depth is sufficient to provide a good bond with the tooth structure and prevent microleakage without causing significant gingival irritation or damage.

Dental Materials
Fluoromica glass ceramics like Dicor have a composition based on mica crystals consisting of silica, potassium oxide (K2O), magnesium oxide (MgO), and aluminum oxide (Al2O3), with zirconium oxide (ZrO2) added for stability. Fluorides are included in the mixture to achieve fluorescence in the finished prosthesis. The material is castable and shares some similarities with traditional dental ceramics but with unique properties derived from its crystalline structure.

Midline diastema is a common condition involving a gap between the two upper
front teeth.
Various orthodontic techniques and appliances can be used to close this space,
which typically involves applying controlled force to move the teeth closer
together.
(a) Lingual bow with inter tooth traction: A lingual bow is an orthodontic
appliance that can be used with traction (force) between teeth to close a
diastema.
(b) Hawley's appliance with finger springs: A Hawley appliance is a type of
removable retainer often used in orthodontics.
It can be modified with finger springs to apply gentle pressure and move teeth,
including closing a diastema.
(c) Bonding tooth and inter tooth elastics: Bonding brackets or buttons to the
teeth and using intermaxillary elastics (rubber bands) is a standard method to
apply force and close gaps.
(d) Use of steel ligature directly on tooth: Applying a steel ligature wire
directly around a tooth to move it would likely cause uncontrolled tilting of
the tooth and potential damage to the tooth and surrounding tissues, rather than
a proper, controlled correction of the diastema.It is not a standard or safe
method for this purpose.
