OBJECTIVE To establish a convenient, objective and applicable method to assess gingival biotype using periodontal probing. METHODS A total of 66 maxillary anterior teeth from 14 volunteers (6 males, 8 females) with healthy gingiva, aged from 20 to 30 years, were recruited in this study. The gingival biotypes were evaluated by whether or not the outline of(More)
OBJECTIVES To develop a novel technique to visualize dentogingival profiles by using cone beam computed tomography (CBCT) and to evaluate the accuracy of mucogingival tissue thickness measurements with CBCT, as compared with direct measurements in vitro. METHODS A silicone matrix loaded with radiopaque impression material was prepared before performing(More)
OBJECTIVE To develop a novel method for obtaining the clear visualization of the gingival profile by cone-beam computed tomography (CBCT) that consistently allows the measurements of gingival thickness and use it to explore the relationship between the gingival thickness and gingival biotype, and the gingival thickness and underlying alveolar bone(More)
A young lady with unsatisfied restorations of upper anterior teeth and swollen gum wanted to improve aesthetics. Oral examination showed that 12-22 were provisional crowns with normal occlusion, poorly gingival contour and gummy smile. The gingiva was red, light swollen and bleeding on probing. X-ray showed the roots of 11, 21 were short and the alveolar(More)
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(More)
OBJECTIVE To investigate the features of the fill of interdental spaces by gingival papillae and the associated factors. METHODS Fifteen volunteers with healthy gingiva were involved in this study. The height and thickness on the alveolar crest level of 62 maxillary anterior papilla were measured radiographically with cone-beam computed tomography (CBCT)(More)
OBJECTIVE To explore a crown form classification method for upper central incisor which is more objective and scientific than traditional classification method based on the standardized photography technique. To analyze the relationship between crown form of upper central incisors and papilla filling in periodontally healthy Chinese Han-nationality youth.(More)
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(More)
