To investigate the influence of change on sense of coherence (SOC) on dental services use in adolescents over a two-year period.
A prospective follow-up study was conducted involving 334 12-year-old adolescents from public schools in the city of Manaus, Amazonas, Brazil. The predictors of use of dental services in the last 12 months were selected according to the Andersen's behavioural theoretical model. The predisposing factors included sex, self-reported skin colour and SOC. The enabling factors were dental insurance, monthly family income and parents/guardians schooling. Dental pain, perceived oral health status, dental caries and gingival status were used to assess need factors. Multivariable Poisson regression with robust variance was used to estimate incidence-rate ratios (IRR) and 95% confidence intervals between the independent variables and use of dental services.
Adolescent's SOC scores decreased significantly between baseline and one-year follow-up. SOC decline decreased the likelihood of using dental services in the last 12 months (IRR = 0.96 95%CI 0.92-0.99). Dental caries (IRR = 1.03 95%CI 1.01-1.04) and gingival bleeding (IRR = 1.01 95%CI 1.01-1.02) remained associated with use of dental services in the last 12 months. Adolescents with dental pain were more likely to have visited a dentist in the last year (IRR = 1.03, 95%CI 1.01-1.06).
SOC decrease over one-year period was a meaningful factor of dental services use among 12-year-old adolescents. Dental pain and clinical conditions were also relevant factors that can influence use of dental services in this group.
调查在两年期间变化对综合感知健康程度（SOC）对青少年看牙服务利用的影响。
本前瞻性随访研究纳入了来自巴西亚马孙州玛瑙斯市公立学校的 334 名 12 岁青少年。根据安德森行为理论模型选择过去 12 个月内使用看牙服务的预测因素。易感性因素包括性别、自我报告的肤色和 SOC。有利因素包括牙科保险、月家庭收入和父母/监护人的受教育程度。使用牙科疼痛、自我报告的口腔健康状况、龋齿和牙龈状况来评估需求因素。采用多变量泊松回归分析（带稳健方差）来评估独立变量与使用看牙服务之间的发病率比（IRR）和 95%置信区间。
青少年的 SOC 评分在基线和一年随访之间显著下降。SOC 下降降低了过去 12 个月使用看牙服务的可能性（IRR=0.96，95%CI 0.92-0.99）。龋齿（IRR=1.03，95%CI 1.01-1.04）和牙龈出血（IRR=1.01，95%CI 1.01-1.02）仍与过去 12 个月使用看牙服务相关。有牙科疼痛的青少年更有可能在过去一年看牙医（IRR=1.03，95%CI 1.01-1.06）。
在过去一年期间 SOC 的下降是 12 岁青少年看牙服务利用的一个重要因素。牙科疼痛和临床状况也是影响该人群使用看牙服务的相关因素。
