assessment of the relationship between oral health and adenoid hypertrophy in children aged 8 to 15 years

Background: the oral health of children is adversely affected by mouth breathing. one of the main reasons for mouth breathing in children is adenoid hypertrophy. consequently, this study aimed to assess the relationship between oral health and adenoid hypertrophy among children aged 8–15 years in the city of babol.methods: this case-control study was conducted on 100 children. the case group included 50 children with adenoid hypertrophy. an ear, nose, and throat (ent) specialist examined the children clinically and referred them to the oral and maxillofacial radiology clinic. the study control group included 50 healthy children. to assess the size of the adenoidal tissues and the dimensions of the upper airways, we assessed the linear cephalometric measurement ptm-ad2. the evaluations consisted of the decayed, missing, and filled teeth (dmft and dmft for permanent and primary teeth, respectively) index, mean periodontal pocket depth, plaque index (pi), and papillary marginal attached (pma) index.results: fifty samples had adenoid hypertrophy. the prevalence of dental caries was significantly higher in children with adenoid hypertrophy compared to healthy children (dmft was 4.10 ± 2.0 and 2.06 ± 0.7, and dmft was 3.52 ± 3.34 and 1.48 ± 1.24, in the case and control groups, respectively). furthermore, the periodontal indices of the case group were significantly greater than those of the control group (periodontal pocket depth was 2.3 ± 0.35 and 1.8 ± 0.23, pi was 2.73 ± 0.26 and 1.13 ± 0.2, and the pma index was 5.71 ± 0.82 and 2.55 ± 0.48, in the case and control groups, respectively).conclusions: in the case group, there was a statistically higher prevalence of dental caries and gingival inflammation than in the control group. therefore, periodical dental visits and preventive dental procedures are recommended for children with adenoid hypertrophy.
