Edentulousness (partial or complete) is a sequel of tooth loss and is an indicator of the oral health status of a population. Edentulousness has a series of deleterious consequences for oral and general health. The aim of this study was to find out the prevalence of edentulousness among patients visiting the dental unit of a tertiary care centre.
A descriptive cross-sectional study was carried out based on hospital records of patients visiting the Department of Oral Medicine and Prosthodontics of a tertiary care centre from 1 January 2019 to 30 December 2019 to see the prevalence of edentulousness. Ethical approval was obtained from the Institutional Review Committee (Reference number: 077/ 078 /40). A convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated.
Among 4697 patients, edentulousness was found in 403 (8.58%) (7.78-9.38, 95% Confidence Interval). Partial edentulous were 263 (65.30%) and complete edentulous were 140 (34.70%). Of the total partial edentulous patient, Kennedy's class III found in 200 (76.05%) was the most common pattern followed by Kennedy's class I in 32 (12.17%), class II in 21 (7.98%) and class IV in 10 (3.80%) patients respectively.
The prevalence of edentulousness was similar to other studies done in similar settings. Since edentulousness is a preventable problem, it should be addressed with high priority.

无牙颌（部分或完全）是牙齿缺失的后果，是人群口腔健康状况的指标。无牙颌对口腔和全身健康有一系列有害影响。本研究旨在了解到访问三级保健中心牙科单位的患者中无牙颌的流行情况。
本研究是一项基于 2019 年 1 月 1 日至 2019 年 12 月 30 日期间访问三级保健中心口腔医学和修复科的患者的医院记录进行的描述性横断面研究，以了解无牙颌的流行情况。本研究获得了机构审查委员会的伦理批准（参考编号：077/078/40）。采用便利抽样法。计算点估计值和 95%置信区间。
在 4697 名患者中，发现 403 名（8.58%）（7.78-9.38，95%置信区间）有牙列缺失。部分无牙颌为 263 例（65.30%），完全无牙颌为 140 例（34.70%）。在总部分无牙颌患者中，最常见的模式是 Kennedy 类 III 200 例（76.05%），其次是 Kennedy 类 I 32 例（12.17%）、类 II 21 例（7.98%）和类 IV 10 例（3.80%）。
无牙颌的流行率与在类似环境中进行的其他研究相似。由于无牙颌是一个可预防的问题，因此应优先解决。
