Background: Global epidemiological studies have reported that the oral health status
of institutionalized children is worse than that of their counterparts in the general
population. This has been attributed to poor oral hygiene and limited access to
preventive or therapeutic dental services. Furthermore, there is inadequate information
on the dental health of Kenyan children residing in Charitable Children Institutions
(CCIs).
Objectives: The main objective of the study was to determine the prevalence of dental
caries, gingivitis and treatment needs of children residing in CCIs in Dagoretti and
Westlands Sub-Counties of Nairobi City County in Kenya.
Study design: This was a descriptive cross-sectional study.
Material and methods: The study population comprised of 170 participants aged 6
to 15 years and who had continuously resided in the selected CCIs for a period of at
least three months. Data was collected for the study using the WHO (2013) simplified
oral health questionnaire for children, administered by the Principal Investigator (PI),
who also carried out the clinical oral examinations of the participants. The
questionnaire gathered information on the participants' socio-demographic profile,
oral hygiene practices, and dietary practices. The oral hygiene status, including the
presence of plaque, gingival health, dental caries status, and treatment needs, were
recorded using a modified version of the WHO (2013) oral health assessment form for
children. A trained and pre-tested assistant recorded the clinical findings.

Data analysis and presentation: The data was analyzed using SPSS version 25 for
Microsoft Windows. The descriptive statistics applied to the continuous data were
summarized as range, mean ± standard deviation while categorical data in percentage.
The inferential statistics applied for comparison of the continuous variables were ttest
and one-way analysis of variance (ANOVA). Categorical variables were
compared by Chi-square (χ2) and Fishers exact test. All statistical tests and hypothesis
testing were determined at 95% Confidence Interval (CI) and p < 0.05 was considered
statistically significant. Data was presented in form of statements, tables, graphs and
pie charts.
Results: Among the 170 study participants, 86 (50.6%) were male and 84 (49.4%)
were female. The mean age of the study participants was 10.7±2.9 SD. While all the
participants reported using a conventional toothbrush and toothpaste, 140 (82.4%)
reported to brushing their teeth once a day, 14 (8.2%) brushed twice daily, 15 (8.8%)
brushed several times a week and one participant (0.6%) reported to brushing once a
week. These findings indicated poor oral hygiene amongst the participants, as
reflected by a mean plaque score of 2.1±0.4 SD. A high prevalence of gingivitis was
also observed, affecting 99.4% of the participants, with a mean gingival index of
1.4±0.3 SD. The prevalence of dental caries was 75.9%, and the mean values for
dmft/DMFT were 0.96 (±1.76 SD) and 1.15 (±1.49 SD) respectively. Based on the
assessment of the periodontal treatment needs, majority of the study participants, 140
(82.4%), required scaling and oral prophylaxis and 30 (17.6%) required improvement
of personal oral hygiene. Regarding dental caries, most of the participants, 99 (76.7%),
xix
required restorations as part of their treatment whilst 19 (14.7%) required pulp therapy,
and 7 (5.65) required extractions.
Conclusion: The study participants had poor oral hygiene status in spite of the
majority of the study participants (82.4%) claiming to brush at least once daily using
a conventional toothpaste and toothbrush. There was a high prevalence of gingivitis
and dental caries in the study participants at 99.4% and 75.9% respectively. The
children also had many unmet dental treatment needs with majority requiring scaling
and polishing, and restorations.
Recommendation: Treatment intervention programs, such as oral health education
and outreach programmes with mobile dental clinics can be undertaken through the
Health Department of the respective county governments, to address the treatment
needs of institutionalized children. A wider multi-centre study is necessary to
determine the burden of oral diseases in institutionalized children. The baseline data
from the study may help in formulation of oral health care protocol in order to provide
preventive and curative oral health services for institutionalized children
