Oral health assessment in children hospitalised in non-surgical paediatric wards: a prospective cohort study and development of a structured inpatient oral health management protocol
This prospective cohort study of hospitalized children in Italy reveals that while oral hygiene behaviors significantly deteriorate during non-surgical admissions and are negatively impacted by pharmacological burden, the lack of routine dental assessment highlights an urgent need for structured inpatient oral health management protocols.

When a child falls ill and is admitted to a hospital, the focus of care naturally turns to the fever, the infection, or the pain that brought them there. Doctors and nurses work tirelessly to stabilize the body's most critical systems, often leaving other aspects of health in the background. Among these overlooked areas is the mouth. While the body fights a systemic illness, the daily routines that keep teeth and gums healthy can easily unravel. Children in the hospital are often tired, in pain, or dependent on caregivers who are themselves stressed and managing complex medical schedules. In this environment, the simple act of brushing teeth can become a low priority, or it may be impossible to perform correctly. Furthermore, many children in the hospital are taking multiple medications. Some of these drugs can dry out the mouth, change the balance of bacteria, or contain sugar that feeds tooth decay. The question researchers have long asked is whether the hospital stay itself, with its disruption of routine and heavy use of medicine, actually makes a child's oral health worse, and if so, how we can stop it.
A team of researchers at the IRCCS Istituto Giannina Gaslini in Genoa, Italy, decided to look closely at this issue. They focused on children aged zero to seventeen who were admitted to general medical wards, such as those for kidney, lung, or nervous system disorders, rather than surgical or intensive care units. These are children who are sick enough to need a hospital bed for at least three nights but are not undergoing surgery. The team wanted to see what happened to the children's mouths from the moment they arrived until the day they went home. They examined the children's teeth and gums, measured the amount of sticky film that builds up on teeth, checked for signs of inflammation, and asked parents about their usual habits at home. They also counted how many different medicines each child was taking, looking for a link between the number of drugs and the condition of the mouth.
The study followed 266 children when they first arrived at the hospital. By the time they were ready to leave, 241 of them had completed the full check-up. The researchers found that while the children's overall dental health did not change drastically during their short stay, their daily habits did. Before coming to the hospital, most of these children brushed their teeth at home. However, once inside the hospital, the frequency of brushing dropped significantly. Fewer children used toothbrushes, and even fewer used toothpaste containing fluoride, which is essential for protecting teeth. This decline happened even though the children were not in a surgical unit where physical limitations might prevent brushing. The researchers also noted that the children's diets changed; they ate fewer sugary snacks and drank fewer sugary beverages while in the hospital, likely because the hospital kitchen controlled the meals. Yet, despite this improvement in diet, the lack of proper brushing meant that the protective habits were not being maintained.
A key discovery was the connection between the number of medicines a child took and the amount of sticky film, or plaque, found on their teeth. Children who were taking more medications tended to have more plaque accumulation. This suggests that the complexity of their medical treatment, perhaps due to the side effects of the drugs or the difficulty of managing a complex routine, made it harder to keep their mouths clean. The researchers also looked at whether the hospital staff were helping with oral care. They found that very few children received advice on how to brush their teeth or had their mouths checked by a dentist while they were patients. Only a small fraction of the children were given dietary advice specifically for their teeth, and even fewer had a dental professional look at their mouths during their stay. This gap in care is significant because the hospital is a place where a child's health needs are already being monitored, yet the mouth remains largely ignored.
Based on these findings, the researchers proposed a new way to handle oral health for children in the hospital. They suggest that when a child is admitted, a simple check of their mouth should happen within the first day. This check would look for pain, signs of decay, or inflammation, and would also see if the child has brought their own toothbrush and toothpaste. If the child is taking many medicines, or if their mouth looks unhealthy, they should be referred to a dentist. The protocol also emphasizes that hospital staff and parents need to be reminded to keep up with brushing twice a day, even when the child is sick. It suggests that after taking medicine, especially liquid medicines that might be sugary or acidic, the child should rinse their mouth with water. Finally, before the child goes home, they should be given clear instructions to continue these habits and to see a dentist if they have any problems.
The study does not claim that a few days in the hospital will cause permanent damage to a child's teeth, as the length of stay was too short to see major changes in cavities or gum disease. However, it clearly shows that the habits that protect teeth are fragile and can break down quickly when a family enters the hospital system. The research suggests that the hospital environment, while good for controlling diet, often fails to support the daily mechanical action of cleaning teeth. By integrating simple oral health checks and reminders into the standard care for sick children, hospitals could prevent the decline in hygiene that currently happens. The goal is to ensure that while a child is being treated for their illness, their mouth is not left behind, and that the hospital becomes a place where preventive care continues rather than stops.
