Children with Cancer

Introduction

The paediatric dentist plays an important role in diagnosis, prevention, stabilisation and treatment of the oral and dental problems that can compromise the child’s quality of life before, during and after cancer treatment. It is essential to have an understanding of the impact of the condition and its treatment on the child’s general heath, and the implications of oral health and comfort, and provision of dental treatment.

Treatment of Childhood Cancers

A combination of the following treatments is used: chemotherapy, radiotherapy, surgery and bone marrow/stem cell transplantation with or without total body irradiation. Chemotherapy and radiotherapy can have profound impact on oral tissues (Table 50.1) and also on provision of dental care.

Table 50.1 Oral effects of cancer treatments.

Chemotherapy Radiotherapy
Infections: fungal, viral, Toxoplasma, or bacterial
Acute dental infections
Chronic periapical infections can become acute
Ulcers and mucositis
Bleeding and marginal gingivitis, petechiae, ecchymoses, bulla formation
Xerostomia can lead to caries and oral infections
Trismus
Pain in the jaw
Delayed and abnormal development
Septicaemia can be spread from oral infection
All effects of chemotherapy can also occur with radiotherapy. Specific issues with radiotherapy are:
 infections
 radiation caries
 pulp pain and necrosis
 tooth hypersensitivity
 trismus
 risk of osteoradionecrosis
 osteomyelitis if bone is affected
 sialadenitis
Long-term oral effects Long-term oral effects
Dental abnormalities such as:
 hypoplasia, microdontia
 taurodontism
 failure of teeth to develop
 root constrictions
Delayed dental development
V-shaped roots
Altered root morphology
Small crown, incomplete calcification

Issues That Need to Be Considered by Dentists

  • The child has been diagnosed with a life-threatening condition. An empathetic approach is required.
  • Some forms of cancer may, and frequently do, have oral manifestations.
  • The cancer, in particular those involving the haemopoietic tissues, may lead to the child’s immune system being compromised (direct immune suppression).
  • Most treatment protocols causes indirect immune suppression which can be severe and will have implications for dental treatment (Table 50.1).
  • Many treatment protocols for the cancer cause oral side-effects.
