Prevalence of dental caries in hospitalized patients with schizophrenia
2016
Background/Aim. It is considered that over 450 million people worldwide
suffer from some form of mental disorder. Previous studies in other countries
have shown that schizophrenia is among the most frequent. Oral health is
significant for general health and should not be separated from mental
health. Studies in other countries have shown an increased incidence of
carious and extracted teeth, and less incidence of filled teeth in this group
of psychiatric patients. The aim of this study was to establish condition of
the existing teeth, to determine the prevalence of caries and to consider
possible risk factors that contribute to the current oral health status of
hospitalized patients with schizophrenia. Methods. The study comprised 190
patients with schizophrenia, hospitalized at the Clinic for Psychiatric
Disorders “Dr. Laza Lazarevic” in Belgrade, and 190 mentally healthy patients
at the Clinic for Periodontology and Oral Medicine, Faculty of Dental
Medicine in Belgrade. The decayed, missing, filled (DMF) index,
sociodemographic and economic characteristics were registered in both groups,
as well as characteristics of the primary disease of hospitalized patients
with schizophrenia. Results. The value of DMF index (representing the sum of
carious, extracted and filled teeth), in the hospitalized patients with
schizophrenia was 18.57 ± 7.07 and 12.47 ± 5.64 in the healthy group (p =
0.000). The structure of the DMF index in the study group showed that caries
and extracted teeth dominated with 88.1%; in the control group, filled teeth
dominated with 55.6%, which was a statistically significant difference for
all the three observed variables. Conclusion. Hospitalized patients with
schizophrenia had twice as many caries and extracted teeth, and five time
less filled teeth than healthy people. The patient’s age and taking
antiparkinsonics were established as predictors of the increased DMF index in
hospitalized patients with schizophrenia.
