Dentoalveolar trauma : Deciduous teeth (‘milk teeth ’) : Alveolar fractures are very rare in children and occur in relation to high velocity. • Always exclude NAI ( non accidental injury ) (particularly in the non- mobile child).
Management of complications in deciduous teeth Avulsed deciduous tooth : Do not re- implant Needs assessment if balancing extractions are required to prevent centre - line shift Intruded deciduous tooth damaging developing permanent tooth bud : The tooth can spontaneously re- erupt over time The developing permanent tooth may be bent ( dilaceration ) prevents normal eruption . Surgery may be required to aid eruption later on so monitor eruption times.
Permanent teeth : Luxation ‘loosening’ injuries : Needs splinting . Lateral luxation/ intrusion/ extrusion : fractures reduced and the tooth splinted . Severely intruded teeth (>6 mm in adults) require surgical repositioning and orthodontics. painkillers , antibiotics, and a mouthwash prescription .
Permanent teeth : Avulsion : chances of saving the tooth rapidly decrease with the amount of time that it has spent out of the mouth tooth fractures :
Dentoalveolar infections : initial infection originates from : Pulpal origin Soft tissue origin ( peridontally – pericoronally ) majority of dentoalveolar infections are mixed anaerobic– aerobic . Based on mode of involvement: - direct involvement in ( 1ry spaces) -indirect involvement in (2ry spaces)
secondary fascial spaces • Masticator( submasseteric-Pterygomandibular - Superficial and deep temporal)
secondary fascial spaces Retropharyngeal • Lateral pharyngeal • Prevertebral Transvers surgical cut at in oblique angle
secondary fascial spaces Parotid space infection
Specific infections : Ludwig’s angina : a bilateral cellulitis affecting sublingual and submandibular spaces -emergency decompression/ -drainage as soon as possible. Commence IV antibiotics ± steroids in the meantime. Periorbital cellulitis : Mainly originates from canine space infection Specially upper canine .
Assessment Take a history of the toothache and associated symptoms Search for: • Airway compromise • Raised FOM (floor of the mouth) • Restricted tongue protrusion • ‘Hot potato voice • Pain on turning the head • Trismus
• Temperature >38.5°C— ‘swinging pyrexia’ with abscess. • Cardiovascular— tachycardia, postural hypotension. • Blood abnormalities— raised white cell count, CRP. • Abscess: localized collection of pus swelling : • Oedema . • Cellulitis
Management • OPG (occasionally USS or CT is required). • WCC , CRP, and glucose. Consider cultures. • IV access and rehydrate. • Commence IV broad- spectrum antibiotics. • Consider corticosteroids in severe swelling . • Keep NBM (nil by mouth) • incision and drainage and extraction of causative teeth .
incision and drainage :
The aim is to keep the abscess cavity open, allowing further exudates to drain. Possible materials: • Yates’ drain (corrugated plastic) • Sterile glove finger • Ribbon gauze. Secure the drain with a non- absorbable suture . Pulling or ‘shortening’ the drain out in stages postoperatively allows the cavity to gradually close up behind it.
Post- extraction complications Bleeding : • Primary haemorrhage — at time of extraction . • Reactionary haemorrhage — up to 24 hours. • Secondary haemorrhage — >24 hours after extraction. Management : Remove all clots and see where the bleeding point is . consider haematology and coagulation blood tests . LA + adrenaline .
Clean the socket and pack it with resorbable cellulose Suture the socket tightly with a horizontal mattress suture of 3- 0 braided resorbable suture or black silk .
