Chat generative pre-trained transformer (ChatGPT) is an artificial intelligence chatbot that uses natural language processing that can respond to human input in a conversational manner. ChatGPT has numerous applications in the health care system including dentistry; it is used in diagnoses and for assessing disease risk and scheduling appointments. It also has a role in scientific research. In the dental field, it has provided many benefits such as detecting dental and maxillofacial abnormalities on panoramic radiographs and identifying different dental restorations. Therefore, it helps in decreasing the workload. But even with these benefits, one should take into consideration the risks and limitations of this chatbot. Few articles mentioned the use of ChatGPT in dentistry. This comprehensive review represents data collected from 66 relevant articles using PubMed and Google Scholar as databases. This review aims to discuss all relevant published articles on the use of ChatGPT in dentistry.

ChatGPT is an artificial intelligence (AI) chatbot developed by OpenAI and it first became available to the public in November 2022. ChatGPT can assist in finding academic papers on the web and summarizing them. This chatbot has the potential to be applied in scientific writing, it has the ability to generate automated drafts, summarize articles, and translate content from several languages. This in turn can make academic writing faster and less challenging. However, due to ethical considerations, its use in scientific writing should be regulated and carefully monitored. Few papers have discussed the use of ChatGPT in scientific research writing. This review aims to discuss all the relevant published papers that discuss the use of ChatGPT in medical and dental research.

Mandible reconstruction is one of the major challenges that face any maxillofacial surgeon worldwide. Different approaches and methods are used for mandible reconstruction, including pedicle flaps, titanium reconstruction plates, and bone grafts. A free fibular flap is used commonly and is considered the gold standard in mandibular reconstruction with a good success rate. Advantages of the free fibula flap include the long pedicle, flexible skin island, good length of dense cortical bone, consistent bone shape, minimal donor site morbidity, superior union rate, anti-collapse effectiveness, segmental blood supply, the potential for two skin paddles, and ease of harvest with a flap survival rate up to 95%. This current review aims to illustrate the approach for mandibular reconstruction using a vascularized free fibula flap.

Excessive gingival exposure (gummy smile) is a non-aesthetic condition characterized by excessive exposure of the gingiva during smiling. The most common cause of gummy smiles was reported to be the hyperfunction of the muscles of the upper lip. Previous reports showed that botulinum toxin (Botox) is effective in the treatment of gummy smiles with a reversible effect, rapid initial action, safe application, low risk, and satisfactory outcome. The effect of Botox is usually observed between one and two weeks. This study aims to review the recent updates and guidelines for gummy smile treatment using botulinum toxin. A literature review was conducted involving relevant studies discussing gummy smile treatment using botulinum toxin with no time restriction. The PubMed and Google Scholar databases were used to gather the most relevant studies. The initial screening revealed 62 studies, and after removing the out-of-scope studies, the final review included 28 studies. Botulinum toxin can be used effectively for the treatment of gummy smile caused by lip dynamics with rarely reported complications. However, the most observed limitation was the temporary duration, which was reported to range from four to six months, and the re-injection of botulinum toxin is usually needed.

The radial forearm free flap has emerged as the mainstay of free flaps for oral cavity soft tissue reconstructions because of its versatility and ability to be used in the reconstruction of large and medium-sized defects. This flap is commonly used to restore head and neck defects, including full-thickness lip and oral cavity defects. This flap offers the opportunity to cover severe defects of the facial region due to its long vascular pedicle and elasticity. In addition to its ease of being harvested, the radial forearm free flap provides a sensate, pliable, and thin skin paddle with a long vascular pedicle. However, it can cause severe morbidity at the donor site, mainly due to exposure of the flexor tendon that results from a failed harvesting of the skin graft, changed sensation in the radial nerve, aesthetic deformity, and reduced range of motion and grip strength. This article aims to review all the up-to-date studies discussing the use of radial forearm free flap in head and neck reconstruction.

A new era in modern dentistry has emerged where tooth loss is no longer an issue as a result of rapid advancements in implantation and alveolar ridge reconstruction. Despite its wide range of indications, autotransplantation is dependent upon careful patient selection and a suitable technique to ensure successful results both functionally and aesthetically. It is possible to restore physiological occlusion, aesthetics, and masticatory function by varying implant length, diameter, surface, and design, along with autogenous, alogenous, alloplastic, or xenogenous bone substitutes. However, none of the technologies that are used in implant dentistry today can adapt to a child’s growing jaw during adolescence. Thus, the young age of the patient restricts implants and creates a challenge for dentists wishing to replace missing teeth. Therefore, tooth autotransplantation can be a good option for treatment. Our objective in this review is to highlight the biological principles required for the successful autotransplantation of teeth. Limits, indications, and prognoses will be analyzed. Hopefully, with increased awareness and acceptance in the dental profession, autotransplantation will become another viable treatment option for those with compromised teeth who still have significant growth potential.
