CONCUSSIONDescription An injury to the tooth-supporting structures

without increased mobility or displacement of

the tooth, but with pain to percussion.

Visual signs Not displaced.

Percussion test Tender to touch or tapping.

Mobility test No increased mobility.

Pulp sensibility test Usually a positive result.The test is important in

assessing future risk of healing complications.

A lack of response to the test indicates an

increased risk of later pulp necrosis.

Radiographic findings No radiographic abnormalities, the tooth is in-

situ in its socket.

Radiographs recommended As a routine: Occlusal, periapical exposure

and lateral view from mesial or distal aspect

of the tooth in question. This should be done in

order to exclude displacement.

Diagnosis

Concussion - Treatment Guidelines

Treatment objectives•Usually there is no need for treatment.

Treatment•Monitor pulpal condition for at least 1 year.

Patient instructions•Soft food for 1 week.Good healing following an injury to the teeth and oral tissues depends, in part, on good oral hygiene. Brushing with a soft brush and rinsing with chlorhexidine 0.1 % is beneficial to prevent accumulation of plaque and debris.

Follow-up•Clinical and radiographic control at 4 weeks, 6-8 weeks and 1 year.

SUBLUXATION

An injury to the tooth supporting structures

resulting in increased mobility, but without

displacement of the tooth. Bleeding from the

gingival sulcus confirms the diagnosis

ETIOLOGY

DIAGNOSTIC SIGNS

Description An injury to the tooth supporting structures resulting in increased mobility, but without displacement of the tooth. Bleeding from the gingival sulcus confirms the diagnosis

Visual signs Not displaced.

Percussion test Tender to touch or tapping.

Mobility test Increased mobility.

Pulp sensibility test Sensibility testing may be negative initially indicating transient pulpal damage. Monitor pulpal response until a definitive pulpal diagnosis can be made.

There will be a positive sensibility test result in about half the cases. The test is important in assessing future risk of healing complications. A lack of response at the initial test indicates an increased risk of later pulp necrosis.

Radiographic findings Usually no radiographic abnormalities.

Radiographs recommended As a routine: Occlusal, periapical exposure and lateral view from the mesial or distal aspect of the tooth.

TREATMENT OBJECTIVE

Usually no need for treatment.

TREATMENT

A flexible splint to stabilize the tooth for patient comfort can be used for up to 2 weeks.

PATIENT INSTRUCTIONS

Soft food for 1 week.

Good healing following an injury to the teeth and oral tissues depends, in part, on good oral hygiene. Brushing with a soft brush and rinsing with chlorhexidine 0.1 % is beneficial to prevent accumulation of plaque and debris.

FOLLOW-UP

Clinical and radiographic control at 4 weeks, 6-8 weeks and 1 year.

EXTRUSION

Partial displacement of the tooth out of its socket. An injury to the tooth

characterized by partial or total separation of the periodontal ligament

resulting in loosening and displacement of the tooth. The alveolar socket

bone is intact in an extrusion injury as opposed to a lateral luxation injury. In

addition to axial displacement, the tooth will usually have an element of

protrusion or retrusion. In severe extrusion injuries the retrusion/protrusion

element can be very pronounced. In some cases it can be more

pronounced than the extrusive element.

ETIOLOGY

DIAGNOSTIC SIGNS

Definition Partial displacement of the tooth out of its alveolar socket.

An injury to the tooth characterized by partial or total separation of the periodontal ligament resulting in loosening and displacement of the tooth. The alveolar socket bone is intact in an extrusion injury as opposed to a lateral luxation injury. Apart from axial displacement, the tooth will usually have an element of protusion or retrusion. In severe extrusion injuries the retrusion/protrusion element can be very pronounced. In some cases it can be more pronounced than the extrusive element.

Visual signs Appears elongated.

Percussion test Tender.

Mobility test Excessively mobile.

Sensibility test Usually lack of response except for teeth with minor displacements. The test is important in assessing risk of healing complications. A positive result to the initial test indicates a reduced risk of later pulp necrosis.

In immature, not fully developed teeth, pulpal revascularization usually occurs. In mature teeth pulp revascularization sometimes occurs.

Radiographic findings Increased periapical ligament space.

Radiographs recommended As a routine: Occlusal, periapical exposure and view from the mesial or distal aspect of the tooth.

TREATMENT

The exposed root surface of the displaced tooth is cleansed with saline before repositioning.

Reposition the tooth by gently re-inserting it into the tooth socket with axial digital pressure (local anesthesia is usually not necessary).

Stabilize the tooth for 2 weeks using a flexible splint.

Monitoring the pulpal condition is essential to diagnose associated root resorption.

Open apex: Revascularization can be confirmed radiographically by evidence of continued root formation and pulp canal obliteration and usually a return to a positive pulp response to sensibility testing.

Closed apex: A continued lack of pulp response to sensibility testing should be taken as evidence of pulp necrosis together with periapical rarefaction and sometimes crown discoloration.

PATIENT INSTRUCTIONS

Soft food for 1 week.

Good healing following an injury to the teeth and oral tissues depends, in part, on good oral hygiene. Brushing with a soft brush and rinsing with chlorhexidine 0.1 % is beneficial to prevent accumulation of plaque and debris.

FOLLOW-UP

Clinical and radiographic control and splint removal after 2 weeks. Clinical and radiographic control at 4 weeks, 6-8 weeks, 6 months, and 1 year.

LATERAL LUXATION

Displacement of the tooth other than axially. Displacement is accompanied by comminution or fracture of either the labial or the palatal/lingual alveolar bone.

Lateral luxation injuries, similar to extrusion injuries, are characterized by partial or total separation of the periodontal ligament. However, lateral luxations are complicated by fracture of either the labial or the palatal/lingual alveolar bone and a compression zone in the cervical and sometimes the apical area. If both sides of the alveolar socket have been fractured, the injury should be classified as an alveolar fracture (alveolar fractures rarely affect only a single tooth). In most cases of lateral luxation the apex of the tooth has been forced into the bone by the displacement, and the tooth is frequently non-mobile.

TREATMENT OBJECTIVE

To reposition and splint a displaced tooth to facilitate pulp and periodontal ligament healing.

TREATMENT

Rinse the exposed part of the root surface with saline before repositioning.

Apply a local anesthesia

Reposition the tooth with forceps or with digital pressure to disengage it from its bony lock and gently reposition it into its original location.

Stabilize the tooth for 4 weeks using a flexible splint. 4 weeks is indicated due to the associated bone fracture.

Monitoring the pulpal condition is essential to diagnose root resorption. If the pulp becomes necrotic, root canal treatment is indicated to prevent infection related root resorption.

In immature developing teeth, revascularization can be confirmed radiographically by evidence of continued root formation, initiation of pulp canal obliteration and usually a return to a positive response to sensibility testing.

In fully formed teeth, a continued lack of response to sensibility testing (i.e. exceeding 3 months) should be taken as evidence of pulp necrosis together with periapical radiolucency and sometimes crown discoloration.

Splint removal: after the fixation period (4 weeks) resin can be removed. If non-composite resin is used it can be peeled off with a dental scaler. If composite is used i should be removed with a bur. The tooth must be supported with digital pressure during this procedure.

PATIENT INSTRUCTIONS

Soft food for 1 week.

FOLLOW-UP

Clinical and radiographic control after 2 weeks. Clinical and radiographic control and splint removal after 4 weeks. Clinical and radiographic control at 6-8 weeks, 6 months, 1 year and yearly for 5 years.

INTRUSION - INTRUSIVE LUXATION

Displacement of the tooth into the alveolar bone. This injury is accompanied by comminution or

fracture of the alveolar socket.

ETIOLOGY

INTRUSION - DIAGNOSTIC SIGNS

Description Displacement of the tooth into the

alveolar bone. This injury is

accompanied by comminution or

fracture of the alveolar socket.

Visual signs The tooth is displaced axially into the

alveolar bone.

Percussion test Usually gives a high metallic

(ankylotic) sound.

Mobility test The tooth is immobile.

Sensibility test Sensibility test will likely give negative

response.

In immature, not fully developed

teeth, pulpal revascularization may

occur.

Radiographic findings The periodontal ligament space may

be absent from all or part of the root.

The cemento-enamel junction is

located more apically in the intruded

tooth than in adjacent non-injured

teeth, at times even apical to the

marginal bone level.

Radiographs recommended As a routine: Occlusal, periapical

exposure and lateral view from the

mesial or distal aspect of the tooth in

question. If the tooth is totally intruded

a lateral exposure is indicated to

make sure the tooth has not

TREATMENT

Tooth intrusion is associated with a potential risk of tooth loss due to progressive root resorption (ankylosis or infection related resorption). The following three methods are only partly evidence based.

Spontaneous eruptionThis is the treatment of choice for permanent teeth with incomplete root formation with minor or moderate intrusion. In teeth with mature root development it is only recommended for teeth with minor intrusion.This treatment seems to lead to fewer healing complications than orthodontic and surgical repositioning. If no movement within a few weeks, initiate orthodontic or surgical repositioning before ankylosis can develop.

Orthodontic repositioningThis treatment may be preferred for patients coming in for delayed treatment. This treatment method enables repair of marginal bone in the socket along with the slow repositioning of the tooth.

Surgical repositioningThis treatment technique is preferable in the acute phase. Intrusion with major dislocation of the tooth (more than 7 mm) may be an indication for surgical repositioning.

Common for all treatmentsEndodontic treatment can prevent the necrotic pulp from initiating infection-related root resorption. This treatment should be considered in all cases with completed root formation where the chance of pulp revascularization is unlikely. Endodontic therapy should preferably be initiated within 3-4 weeks post-trauma. A temporary filling with calcium hydroxide is recommended
