人类牙齿表面龈上菌斑的自然积累与牙龈炎症和常见口腔疾病的发生有关。本研究评估预防后牙菌斑和牙龈炎评分在牙弓内的分布。计划筛选来自印度达瓦德地区的成人受试者，代表提供书面知情同意书的一般人群。本平行设计研究招募了18岁以上的健康受试者，目前不需要任何医疗或牙科护理，并且至少有20颗天然牙齿。入组受试者（n = 41）在基线访视时分别使用Turesky改良Quigley-Hein和Löe-Silness指数进行牙菌斑（PI）和牙龈炎（GI）口腔检查，随后进行全口牙齿预防。在接下来的30天里，受试者每天两次使用含氟牙膏进行口腔卫生。在第15天和第30天召回受试者，进行与基线相同的PI和GI检查。分析表明，在所有检查中，任一牙弓和整个口腔的PI和GI平均评分分别高于2和1。前表面始终表现出较低的PI分数比后部地区的任何一个弓，或整个牙列。牙列内的区域GI差异与PI评分相似，前牙评分低于后牙。预防性治疗降低了PI和GI的频率和平均评分，与足弓无关，在所有回忆访视期间，观察到前部的评分低于后部。与前表面相比，磨牙和舌侧区域始终表现出较高的PI和GI评分。在所有检查中，前庭近端的牙菌斑和牙龈炎的平均评分均高于前庭中部。在牙列内观察到的PI和GI差异具有几个实际意义：（a）口腔健康的全口评估具有优势（B）需要口腔卫生制剂来减少后部区域的牙菌斑沉积和由此产生的牙龈炎症，以及（c）需要持续的口腔卫生教育。
The natural accumulation of supragingival plaque on surfaces of human teeth is associated with gingival inflammation and the initiation of common oral diseases. This study evaluated the distribution of dental plaque and gingivitis scores within the dental arches after prophylaxis. Adult subjects from the Dharwad, India area representing the general population who provided written informed consent were scheduled for screening. Healthy subjects over the age of 18 years, not currently requiring any medical or dental care, and presenting with a complement of at least 20 natural teeth were recruited for this parallel design study. Enrolled subjects (n = 41) underwent oral examinations for dental plaque (PI) and gingivitis (GI) using the Turesky modification of the Quigley-Hein and the Löe-Silness Index, respectively, at the baseline visit, followed by a whole mouth dental prophylaxis. Subjects were given fluoride toothpaste for twice daily oral hygiene for the next 30 days. Subjects were recalled on days 15 and 30 for PI and GI examinations identical to baseline. Analyses indicated that mean scores for PI and GI on either arch and the whole mouth were higher than 2 and 1, respectively, during all examinations. Anterior surfaces consistently exhibited lower PI scores than posterior regions of either arch, or the entire dentition. Regional GI differences within the dentition were similar to PI scores, with lower scores on anterior than posterior teeth. Prophylaxis reduced both the frequency and mean scores of both PI and GI, irrespective of arch, with lower scores observed on anterior than posterior regions during all recall visits. Molar and lingual regions consistently exhibited higher PI and GI scores compared with anterior surfaces. At all examinations, mean scores for both plaque and gingivitis were higher on approximal vestibular than mid-vestibular surfaces. Differences observed in PI and GI within the dentition have several practical implications: (a) there are advantages of whole mouth assessments for oral health (b) a need for oral hygiene formulations to reduce the larger deposits of dental plaque in the posterior region and resultant gingival inflammation, and (c) a requirement for ongoing oral hygiene education.
