## Özet

Experts say that chemotherapy and radiotherapy applied in childhood cancers can also affect oral and dental health.
 Asst. Prof. Buse Yılmaz Şen from the Department of Pediatric Dentistry points out that mouth sores, dryness, infection, and gum problems can negatively affect the treatment process, “In children who receive radiotherapy to the head and neck region, salivary glands may be affected, leading to permanent dry mouth and trismus, which restricts jaw movements. In the long term, especially if the treatment was applied at a young age, tooth development can also be affected.”

## İçerik

Asst. Prof. Şen stated that it is important to identify infection foci in the mouth before cancer treatment and emphasized that regular and non-traumatic oral care should be maintained during treatment. Asst. Prof. Şen also stressed that dental check-ups should not be considered separate from cancer treatment.

 Asst. Prof. Buse Yılmaz Şen from the Department of Pediatric Dentistry at Üsküdar University Dental Hospital made statements regarding the effects of chemotherapy and radiotherapy on children's oral and dental health, and the importance of preventive oral care before and during treatment, within the scope of Childhood Cancers Awareness Month (Golden September).

**Chemotherapy and radiotherapies affect oral and dental health!**

 Asst. Prof. Buse Yılmaz Şen stated that chemotherapy and radiotherapy, especially when applied to the head and neck region in childhood cancers, can directly affect the mouth and teeth, saying, “One of the most common problems is redness, sensitivity, and the formation of sores in the oral mucosa. This condition is called ‘oral mucositis’ and can cause severe pain, difficulty eating, and sometimes even speaking.”

 Asst. Prof. Şen also pointed out that dry mouth, taste changes, tooth sensitivity, increased dental caries, gum problems, and fungal or viral infections can occur, adding, “In children who receive radiotherapy to the head and neck region, salivary glands may also be affected, leading to permanent dry mouth and trismus, which restricts jaw movements. In the long term, especially if the treatment was applied at a young age, tooth development can also be affected. Anomalies in tooth shape and size, enamel development problems, non-development of some teeth, and changes in jaw-facial development can be observed.”

**Oral lesions that do not heal or last longer than 14 days should be taken seriously!**

 Asst. Prof. Şen stated that mouth sores can start as redness, sensitivity, and burning, then turn into painful ulcers, saying, “A child may avoid eating, drinking, or brushing their teeth. Especially in young children, pain may not be expressed verbally, so loss of appetite, crying while eating, or resistance to oral care are important clues.”

 Asst. Prof. Şen highlighted situations that families should particularly pay attention to, stating, “If the child cannot take liquids or food, if mouth sores are rapidly increasing, if there is significant bleeding, or if changes suggesting an infection appear in the mouth, it is important to contact their doctor without delay. Additionally, since the immune system is suppressed during treatment, symptoms of infections may not always be obvious. Oral lesions that do not heal or last longer than 14 days must also be evaluated.”

**Gum problems should be evaluated together with treatment and oral care!**

 Asst. Prof. Şen stated that gum recession is not considered one of the most typical and direct consequences of cancer treatment, and said the following:
“However, deterioration of oral health, dry mouth, changes in nutrition, and neglect of oral care during the treatment period can negatively affect gum tissues. Due to pain and mucositis in the mouth, the child may not be able to brush their teeth sufficiently. This situation can increase bacterial accumulation in the mouth. On the other hand, incorrect or traumatic brushing can also damage gum tissues. Therefore, it is not correct to evaluate gum changes solely as a ‘side effect of cancer treatment’; the treatment itself and changes in oral care should be evaluated together.”

**Infection foci in the mouth should be eliminated before cancer treatment! **

 Asst. Prof. Şen pointed out the importance of treating existing caries, gum disease, or infections before chemotherapy, stating, “The main reason for this is the suppression of the child's immune system during chemotherapy. A dental infection that is normally under control can become much more serious when the immune system is weakened and can negatively affect the course of treatment.”

 Asst. Prof. Şen noted that the ideal approach is to eliminate existing or potential infection foci in the mouth before cancer treatment begins, and stated, “The priority is the treatment of dental infections, advanced dental caries, severe periodontal problems, teeth with poor prognosis, and conditions that constantly irritate oral tissues. The goal here is not to delay cancer treatment by treating teeth. On the contrary, it is to eliminate, as much as possible, risks that could cause serious infections in the future, without unnecessarily delaying oncology treatment.”

**The basic approach should be to keep the inside of the mouth as clean and free from trauma as possible! **

 Asst. Prof. Şen provided information on how the preventive oral and dental care protocol should be for pediatric oncology patients, saying:
“The basic approach is to keep the inside of the mouth as clean and free from trauma as possible. As long as the child's general condition permits, they should clean their teeth and tongue 2–3 times a day with a soft-bristled toothbrush. Maintaining oral hygiene during cancer treatment helps manage the risk of infection and mucositis by reducing the microbial load in the mouth.
Fluoride toothpaste should be used; if there is a risk of caries and dry mouth, additional fluoride-containing protective applications should be planned by the doctor. In terms of nutrition, it should also be remembered that sugary medications and high-carbohydrate supplements can increase the risk of caries. During periods of pain or mucositis, very hot, spicy, hard, crunchy, and acidic foods should be avoided. Additionally, in children who develop dry mouth, frequent water intake, sugar-free gum or appropriate saliva-stimulating products, and choosing alcohol-free oral care products can be beneficial.
If the child can use dental floss correctly and without causing trauma, daily use can be continued. However, if bleeding or pain occurs, the affected area should not be forced. During periods when immune and blood cell counts are very low, the use of toothpicks or some water-jet devices that could harm the gums is not recommended.”

**Dental check-ups are not a separate issue outside of cancer treatment! **

 Asst. Prof. Buse Yılmaz Şen emphasized that oral health should be seen as an inseparable part of cancer treatment, stating, “Cancer treatment is not just about treating the disease; it is also important for the child to be able to continue the treatment safely and as comfortably as possible. The mouth is one of the most important parts of the body connected to the outside. An infection in the mouth or severe sores that develop during treatment can affect the child's eating, fluid intake, and general condition; in some cases, it can even complicate the cancer treatment plan.”

 Therefore, Asst. Prof. Şen underlined that dental check-ups are not a separate issue outside of cancer treatment and concluded her remarks as follows:
“On the contrary, identifying problems that could cause infection in the mouth before chemotherapy or radiotherapy begins, maintaining oral hygiene during treatment, and early management of potential side effects support the child's quality of life and the safety of the treatment process. In short, a healthy mouth does not just mean healthy teeth; for a child undergoing cancer treatment, it is also an important part of overall health.”
