N ursing caries is a frustrating condition that is difficult to treat in infants andveryyoungchildren. It mayretard the child's health, development,and speech. It can be painful, is infectious, and results in impairmentof nutrition and esthetics with accompanyingpsychological problems.1 The risk factors for nursing caries vary from population to population, and someadditional factors maybe present in a population due the sociocultural differences in different geographical locations. The aim of this investigation was to study characteristics of nursing caries children in central Saudi Arabia by obtaining information about their socioeconomicstatus, feeding practices, use of sweetened pacifiers, and other relevant information mentionedin the literature byvarious researchers,2 5 by using a self-administered questionnaire. Such a profile mayhelp identify high-risk groups, which in turn may help target preventive measuresto children at high risk for nursing caries. Methodsand materials This cross-sectional study used a conveniencesample of 96 children from those seeking treatment or referred to College of Dentistry, both in the Dariyah and Malaz campusesof KingSaudUniversity in Saudi Arabia. Any child aged 6 years or younger diagnosed as having nursing caries was included in the study. The criterion used for the diagnosis of nursing caries was caries on the labial surfaces of at least two maxillary primary incisors. A dental examination was performed in the dental operatory setting and findings recorded. Information about feeding patterns, pacifier use, socioeconomicstatus, and first visit to a dentist wasobtained from parents through a self-administered questionnaire. The questionnaire was produced in Arabic and assistance was provided to the parents if required. Data were entered into a computer and Statistical Analyses System (SAS) was used to formulate one-way and two-wayfrequency distribution tables.
Results Socioeconomcicharacteristics Parents of 96 nursing caries children, 53 maleand 43 female, completed the questionnaire. The meanage of the children was 55 months (+ 17.0). The meannumber of children per familywas4.36 (+ 2.48). Forty-two(43.8%) children werethe first or second born, while 23 (23.9%) werethird or fourth and 31 (32.3%)were fifth or above. Agreat majority (94.8%)of the children wereliving with both parents. Onlyfive (5.2%) children wereliving with the father only, motheronly, or other relatives. The percentage of nursing caries children (14.7%) with fathers of very high socioeconomicclass was very low (Table 1). Agreat majority (75.6%)of mothers full-time housewives. Many(41.7%) of the mothers had only primary or lower education, while the opposite wastrue for the fathers (Table2). Brushingpractices Fifty-nine (61.5%) children had commenced toothbrushing, but only 16 (16.7%) started brushing before age 24 months. The meanage whenthe brushing commencedwith or without assistance was 34 months(+ 16.7).

to nursing caries, with the first-born children presenting a higher experience of nursing caries. 5 This can be attributed to the relative lack of experienceon the part of newparents in managinga child's behavior, and lack of dental Health Education and dietary counseling. A majority of the children had middle socioeconomic class fathers and less educated mothers, whichagrees with findings that nursing caries tends to be associated with low educational level of mothers6, 7 and lower Socioeconomic status. 6 A study by Johnsen8 showedthat parents of nursing caries children wereless likely to have attended college.

not only very late compared with present-day recommendations, but also much later than reported in a s6imilar sample by Dilley et al. Feeding practices The controversial issue of cariogenicity of human breast milk is still unresolved. Somereports show that nocturnal and at-will/on-demand breast feeding are associated with nursing caries, 9,10 other studies report that breast-fed children are actually less likely to develop caries than are bottle-fed children2 I, 12 The mean age when the breast feeding stopped of 17.6 months (+ 9.5) was not very high, as expected, but more than half
study parents started giving sweet solids to the children at an early age and with an average frequency of twice a day. High-carbohydrate diet such as bakery products is an important part of the Saudi culture. The effects of this high carbohydrate diet might not be as harmful to the adult population as it is to children because of delayed onset of tooth cleaning and / or irregular oral hygiene maintenance. Pacifier use The use of sweetened pacifiers has also been associated with nursing caries. 2, s In this study very few parents (6.3%) gave sweetened pacifiers to their children.
of the children were breast-fed at bed-time, a previously established nursing caries risk factor. In this study, few (19.8%) children were bottle-fed with cow's milk. This may be because fresh cow's milk isn't available and milk formula is considered a better substitute for humanbreast milk. About three-quarters (70.8%) of nursing caries children were bottle-fed with
Pacifier use in general also was low (28.1%). It is a commonobservation that the pacifier use in the study area is very low. It could be due to the fact that weaning from the bottle is very late and sucking requirements of the child are fulfilled by bottle use. Moreover, use of domestic child care assistance in Saudi Arabia is very commonso children get the required attention, which

often eliminates the use of pacifiers for soothing. First dentalvisit The meanage of first dental visit (42.4 months+ 17.6) was much higher than the recommended age for first dental visit. The present recommendations for first dental visit range from as soon as the first teeth erupt to I year of age. It can be expected that an earlier routine visit to a dentist might prevent this condition because it affords the dentist an opportunity to provide parents with information about healthy feeding habits and oral hygiene. This is particularly true of new parents. The aim of this study was to determine the characteristics of nursing caries children in a Saudi popu-
lation. Therefore, no comparison group was used. It

This is not as high as expected or as reported by other research in similar studies in diff6e,1re3nt populations. In our study three-fourths (75%) of children took fruit juices and carbonated beverages in the feeding bottle, and more than one-fifth (21.9%) took the bottle to bed.
