Article Synopsis
- - This study proposes a new deep learning model to improve the prediction of treatment effectiveness for periodontal disease at an individual site level, addressing the limitations of current predictive tools.
- - The model was developed using data from 9,273 Chinese patients and utilizes a Sequence-to-Sequence framework with an Attention mechanism to enhance its accuracy.
- - Results showed that the model achieved a high site-level accuracy of 92.4% for probing depth predictions, indicating its potential for effective clinical application, especially for baseline probing depths under 5 mm.
Background: There is limited evidence of the effects of local anesthesia (LA) on outcomes of non-surgical periodontal treatment (NSPT), in particular among the Chinese. This retrospective cohort study aimed to evaluate the effects of LA on short-term treatment outcomes of NSPT and to determine under what circumstances LA should be prescribed to improve these outcomes.
Methods: Data from periodontal examinations of 3980 patients were used.
Aim: This study aimed to evaluate clinical performance of non-surgical periodontal treatment (NSPT) and its influential factors in a large Chinese population with generalized aggressive periodontitis (GAgP).
Material And Methods: Longitudinal periodontal examination data of 1,004 GAgP patients (numbers of patients with observation periods 6 weeks~, 3 months~, 6 months~, 1 year~, 3 years~ and >5 years were 203, 310, 193, 205, 70 and 23, respectively) were extracted from a hospital-based electronic periodontal charting record system and analysed by multilevel analysis.
Results: Mean probing depth (PD) and attachment loss (AL) reductions at patient level were 1.
Aim: The aim of this study was to evaluate the effectiveness of non-surgical periodontal treatment (NSPT) and its influential factors in a large Chinese population with chronic periodontitis.
Methods: Periodontal examination data of 10,789 patients with at least one periodontal re-evaluation record were extracted from a hospital-based electronic periodontal charting record system. Probing depth (PD) and bleeding index (BI) reductions after NSPT and their influential factors were analysed by multilevel analysis.
Objectives: This study aimed to classify the dynamic smile and to quantify the gingival line (GL), as well as apico-coronal displacement of the gingival zenith (GZ), in the maxillary anterior dentition in a young Chinese population.
Methods: Two-hundred young Chinese subjects (100 men and 100 women; 20-35 years of age) with healthy dentogingival tissue were recruited. The dynamic smile process was captured using a digital camera.
[Shape analysis of healthy gingival curve in maxillary anterior teeth in 120 Chinese youth].

February 2013
Objective: To establish the relationship of the gingival crest, the gingival curve characteristic point (inflection point, IP) and the contact points and to use it as reference to design the location of contact area in anterior teeth restoration to form the natural papillae.
Methods: Two-dimensional gingival curve morphology analysis based on standardized digital images was done to measure the value of different points in the upper anterior teeth for 120 young Chinese.
Results: In the maxillary anterior teeth, the average mesial papilla heights(MPH) of central incisors(CI), lateral incisors(LI), canines(CA) were (4.

March 2012
Objective: To investigate the smile esthetic elements of Chinese Han-nationality female based on high definition (HD) digital camera with computer-image measuring technique.
Methods: HD digital camera was used to capture spontaneous smile process combined with computer-image measuring technique to establish the analysis method of smile. Ninety-nine Han-nationality female with normal gingiva, aged from 20 to 30 years were recruited.
[Cooperative development and application of electronic periodontal examination chart].
Zhonghua Kou Qiang Yi Xue Za Zhi
December 2009
Objective: To develop an electronic system (software) for collecting and analyzing periodontal examination data, and preliminarily evaluate its clinical application.
Methods: The contents and frame of electronic periodontal examination system were designed based on the aim and requirement of periodontal examination, and the software system was developed under the assistance from computer engineers. The electronic system was implemented for entry, storage, retrieval and output of clinical data and data conversion.
