Abstract:
Aim: The aim of this study was to determine the characteristic feautures of occlusion in
primary dentition; to examine the relationship between existing malocclusions and caries, bad
oral habits, sociodemographic data and nutrition and to show its reflection to Turkish children.
Materials and Methods: This study was a cross-sectional, epidemiological study that
includes dental examinations and face-to-face interviews with 500 mothers of 3-6 years old
children who applied to Marmara University Faculty of Dentistry Department of Pedodontics
for various reasons. In the study, the sociodemographic data of the mother and child, the
feeding patterns of the child until the first 2 years of age, bad oral habits and breathing pattern
were questioned. In the dental examination, the relationship between second primary molars,
canine relationship, primate and physiological spaces, presence of posterior cross bite,
overbite, overjet, anterior crowding and midline shift were examined. The state of oral health
was scored according to the CAST index. Results: The most common molar relationship was
55.4% vertical, 28.2% distal and 16.4% mesial respectively. Primary canine relationships
were 66.4% class 1, 25.4% class 2, 8.2% class 3. 77.8% of the participants had at least one
type of malocclusion, and 51% had at least one type of bad oral habit. The most common
malocclusion was midline shift. Anterior crowding, deep bite, increased overjet, head-to-head
bite, posterior crossbite, and anterior crossbite were followed by the midline shift. The most
common bad oral habit was bruxism. Then nail-biting, infantile swallowing, lip sucking, finger
sucking and object biting are observed, respectively. Breastfeeding was the primary source of
nutrition for the children participating in the study until the first 2 years of age. 54.8% of the
participants never used the bottlefeeding. Those who use pacifiers account for 37.8% of the
population. At least one decayed tooth was detected in 81.6% of the participants. Conclusions:
A statistically significant relationship was found between malocclusions occurring in children
aged 3-6 years who applied to Marmara University Faculty of Dentistry, bad oral habits,
feeding patterns in the first 2 years and caries.
