The authors conducted a retrospective-casuistic study to determine the prevalence of nonsyndromic multiple hyperdontia in a sample of the population of Madrid, as well as possible complications associated with the presence of such supernumerary teeth.
The study included a data assessment of all patients seeking dental care at a hospital's department of oral surgery across four years. The authors studied data from patients who had nonsyndromic multiple hyperdontia. We used univariate and bivariate analysis to make comparisions between variables.
The authors identified nonsyndromic multiple hyperdontia in the records of 13 patients (0.1 percent) of the total population studied. These patients had 55 supernumerary teeth. Premolars were the most frequently seen type of supernumerary tooth and constituted 45.5 percent of the sample.
Nonsyndromic multiple hyperdontia usually is diagnosed as a coincidental radiographic finding in the course of routine examination rather than as the result of an associated disease. However, the authors found a higher percentage of comorbidity than they initially expected; mechanical or obstructive pathology was associated with 20.0 percent of the supernumerary teeth and enlargement of the follicular sac of more than 3 millimeters was present in 23.6 percent of the sample.
The early diagnosis and follow-up of patients with multiple supernumerary teeth should help clinicians prevent the diseases associated with this kind of hyperodontia.
作者进行了一项回顾性病例研究，以确定马德里人群中多发非综合征性多生牙的流行率，以及与存在此类额外牙齿相关的可能并发症。
该研究评估了四年内在一家医院口腔外科就诊的所有患者的数据。作者研究了患有非综合征性多发性多生牙的患者的数据。我们使用单变量和双变量分析来比较变量之间的差异。
作者在研究的总人群记录中发现了 13 名（0.1%）非综合征性多发性多生牙患者。这些患者有 55 颗额外牙齿。前磨牙是最常见的额外牙类型，占样本的 45.5%。
非综合征性多发性多生牙通常在常规检查过程中被诊断为偶然的影像学发现，而不是相关疾病的结果。然而，作者发现比最初预期更高的共病率；20.0%的额外牙齿存在机械或阻塞性病变，23.6%的样本中滤泡囊增大超过 3 毫米。
早期诊断和随访多发性多生牙患者有助于临床医生预防与这种多生牙相关的疾病。
