What are the classes of tooth fracture?

Class I – No fracture or fracture of enamel only, with or without loosening or displacement of the tooth Class II – Fracture of the crown involving both enamel and dentin without exposure of the pulp and with or without loosening or displacement of the tooth Class III – Fracture of the crown exposing the pulp, with or …

What is Ellis Class 3 fracture?

Ellis class III fracture is a fracture of the crown with an open pulp. Teeth with exposed pulp will cause irritation of the pulp resulting in pulp inflammation (pulpitis).

What is the difference between Colles fracture and Smith fracture?

Smith fractures do not extend to the wrist, hence they are extra-articular. These fractures are usually transverse. Smith fractures are rare and are most often seen in elderly women or young men. A Colles fracture is a broken wrist.

What is an uncomplicated crown fracture?

An uncomplicated crown fracture will involve the enamel and the dentin layers of a tooth. It does not involve any exposure of the pulp. The complicated fracture will also involve exposure of the pulp. The treatment for the uncomplicated crown fracture works to preserve the pulp of the tooth.

Is Barton fracture intra articular?

Barton fracture: an intraarticular fracture involving either the dorsal or the volar lip of the distal radius resulting in either dorsal or volar subluxation of the lunate.

What is Ellis classification?

The trauma cases were identified according to Ellis classification [18] as modified by Holland et al., 1988 [19] as follows: Class 1: Fracture of enamel only; Class 2: Fracture of enamel and dentine, without pulp involvement; Class 3: Fracture of enamel and dentine with pulp involvement; Class 4: Discoloration of the …

What is a Smiths fracture?

A Smith fracture is a break to the end of the radius. The end part of the bone, which forms part of the wrist joint, is displaced or angled in the direction of the palm of the hand. Often, this injury occurs by a fall to the back of a flexed wrist but can occur in any fall to an outstretched hand.

What are the different types of volar Barton fractures?

Purpose: We described a morphological classification and grading system for volar Barton fractures. Methods: We divided these fractures into four types: typical Barton, ulna Barton, radial Barton, comminuted Barton. Moreover, we graded the fractures into two degrees: simple split and split-depression.

What percentage of Barton fractures are Grade 2?

The distribution of typical, ulna, radial and comminuted Barton type fractures was 69 %, 7 %, 5 % and 19 %, respectively. Grade 2 fractures accounted for 49 % in our series. Conclusions: This classification and grading system of Barton fractures is likely to have implications in terms of pathophysiology and surgical technique.

What is a Barton fracture of the radius?

Barton fracture: an intraarticular fracture involving either the dorsal or the volar lip of the distal radius resulting in either dorsal or volar subluxation of the lunate. chauffeur’s fracture: displaced fracture of the radial styloid accompanied by ulnar translocation of the carpus.

What are the different classes of dental crown fractures?

Class I – Simple crown fracture with little or no dentin affected Class II- Extensive crown fracture with considerable loss of dentin, but with the pulp not affected. Class III- Extensive crown fracture with considerable loss of dentin and pulp exposure. Class IV – A tooth devitalized by trauma with or without loss of tooth structure.
