An Oral Health Status and Treatment Needed in Relation to Dental Knowledge, Among a Group of Children Attending Preventive Department, College of Dentistry, University of Baghdad


Background: Oral health represents an important base for human well-being; the heath of the body begins from oralcavity. Great deal has been applied to increase knowledge in the field of oral health in order to developappropriate preventive program. This study was conducted in order to estimate the percentage and severity ofdental caries and gingivitis among children attending Preventive Department in Collage of Dentistry, University ofBaghdad and to determine dental treatment need for those patients, further more to study the relation of thesevariables with dental knowledge.Materials and Methods: The study group consists of 163 children with an age ranged from 6 to 14 years, whoattended the preventive clinic for the first time to be involved in preventive program. Plaque index and gingivalindex were applied for examination of dental plaque and gingivitis, dental caries and treatment need was recordedaccording to criteria described by WHO. Dental knowledge of each child was evaluated by ten questions preparedfor this reason.Results: The results showed that caries-experience among permanent teeth represented by DS and DMFS were (3.22± 0.31 and 4.09 ± 0.35) respectively, while caries-experience among deciduouse teeth represented by ds and dmfswere (6.79 ± 0.61 and 9.03 ± 0.81) respectively. Analysis of variance (one way ANOVA test-) showed that cariesexperience among permanent teeth increased with age (P < 0.001), while caries-experience among deciduousteeth decreased with age (P 0.001). The majority of studied sample were in need for one surface filling (93%)followed by two or more surface filling (66%). High percentage of children involved in this study had mildaccumulation of plaque and mild gingivitis (69.93% and 83.43%) respectively. Evaluation of dental knowledgeamong those children showed that 67% of them had good dental knowledge (scores 5), but weak correlationswere recorded between good dental knowledge and caries experience for deciduous teeth(r=0.12, P > 0.05) and forpermanent teeth (r=0.22, P<0.05).The same correlation was recorded between dental plaque and dental knowledge(r=0.05, P> 0.05).Conclusion: those children need further motivation and instructions to improve their dental knowledge and toimprove their attitude to change their behavior towards further improvement of oral hygiene and oral health
