ABSTRACT
Objectives:
The aim of this study was to determine the relationship between malocclusion, lip competenceand gingival health among a sample of school children. Material andmethod:
A multi stagesampling technique was used to randomly select 239 school children. Malocclusion was evaluated andgraded from the childrens dental casts using the Dental Aesthetics Index (DAI) and Littles IrregularityIndex (LII). The lips were examined for competence according to Jacksons classifi cation. Gingival healthwas assessed using the Plaque Index and Index of gingival infl ammation.Results:
A mean DAI scoreof 26.37 ± 6.67 was obtained while the mean score of the LII was 1.88 ± 1.68 mm. Majority of thechildren (97.1%) had competent lips. Results of correlation tests between DAI scores and the periodontalindices were low and not statistically signifi cant, while that of the LII score and periodontal indiceswere also low but statistically signifi cant (p < 0.05).Conclusion:
A cause and effect relationship couldnot be established between malocclusion and gingivitis. A weak correlation exists between malocclusionassessed by the DAI and LII and periodontal indices used. This supports the opinion that prescribingorthodontic treatment solely for the purpose of maintaining periodontal health is not justified.
