The use of Artificial Intelligence (AI) is rapidly expanding. While it comes with some drawbacks, it also offers numerous advantages. One significant application of AI is chatbots, which utilize natural language processing and machine learning to provide information, answer queries, and assist users.

In most studies, some structures in the hard tissue have been measured and statistically analyzed. However, none of the studies has analyzed this foramen in regard to its location with overlying soft tissues, which is so clinically relevant.

These mucogingival alterations may become a challenge to manage in the maxillary anterior region among patients with a high lip line upon smiling or high esthetic demands. To further complicate matters, the presence of physiologic gingival pigmentation in the esthetic zone creates challenges of its own.

In today's dentistry, tooth shape is a critical factor when dental implant prostheses are considered in the esthetic zone. The major esthetic goal for this type of restoration is to achieve the closest possible symmetry with the adjacent tooth, both at the soft and at the hard tissue levels.

The purpose of this study was to objectively define and quantify triangular, square, and square/tapered maxillary central incisors. In this study, the shape of maxillary central incisor crowns was investigated in 100 healthy individuals. The results showed that when the contact surface/crown length ratio is less than 43%, the tooth is triangular in shape; when the ratio is more than 57%, the tooth is square in shape; and when the ratio is between 43% and 57%, the tooth is defined as square/tapered.

Additional factors such as ethnicity should be considered to produce a more comprehensive analysis.
Purpose: The purpose of this study is to compare the anatomic crown dimensions of extracted maxillary teeth in Asian and white populations.

Crown width/length ratios have been considered an important aspect in the esthetic zone. Because previous investigations focused on Caucasian populations, limited information is available on other ethnic groups to propose a comprehensive approach to anterior maxillary teeth. The purpose of this study was to analyze the dimensions of anatomical crowns of maxillary anterior tooth groups with respect to width, length, and width/length ratios among an Asian population.

This paper presents a clinical case of a novel incision-flap design used to advance the flap to enhance tension-free primary closure for the vertical ridge augmentation.
Methods: A 61-year-old white man presented with the chief complaint of wanting to replace his posterior mandibular teeth.
