Study summary
The goal of this observational study is to learn how to better predict and prevent intra- and postoperative complications in oral surgery in adult patients referred for oral surgical procedures. The study aims to understand how accurately surgeons can foresee complications and which patient, tooth, and surgery related factors influence the outcomes.
The research questions are:
* What is the incidence of intra and postoperative complications in oral surgery?
* Which factors predict these complications, and how accurately can surgeons anticipate them?
* Can the development of an AI tool reduce postoperative complications?
Participants will:
* Receive standard oral surgery treatment at a private referral clinic (Specialtandlægerne Sjælland).
* Have clinical information collected about their procedure, medical history, and personal characteristics (including anxiety level).
* Conduct a short questionnaire, the STAI-6 and the I-PANAS-SF.
* Have the surgeon record their prediction of whether complications are expected.
* Be followed in the postoperative lapse to document whether complications occur after surgery.

Inclusion Criteria:
* Patients reffered from a general dentist practicioner for the following surgeries: third molar removal, apicoectomy, dental implant placement.
* Patients \>15 years of age
* A valid diagnosis prior to the surgery
* Cases with fully completed questionnaires.
Exclusion Criteria
* Pathological condition requiring hospital refferal
* Complications following re-surgery
* Re-assesment of the diagnosis from the general dentist practicioner
Specific for apical surgery:
* Root fracture present.
* Buccal bone height \<3mm.
Specific for third molar removal:
\- if coronectomy is conducted instead of total root removal.
Specific for dental implant:
* if an implant has been placed before in the same region of interest.
* Health conditions were dental implants are contraindicated.
Primary outcome measure(s)
Intraoperative and postoperative complications — Baseline/Day 1: day of surgery. 1. Follow-up 7-10 days after surgery. Emergency follow-up: baseline and through study completion. Apical surgery: 2. follow-up 1 year. Dental implant: 2. follow-up. If sensory impairment 3. month follow-up and up to 1 year Intraoperative and postoperative complications and to set up a prediction model. Intraoperatively: unplanned tooth extraction, damage to adjacent structures; injury to hard tissue (bone fracture), soft tissue (lacerations or burns), maxillary sinus perforation, macroscopic nerve injury/rupture, root displacement/root tip fracture, oroantral communication, root displacement, hemorrhage, aspiration or ingestion. Specific for dental implants: an unplanned implant placement or lack of osseointegration.
Postoperatively: Surgical site infection (SSI) with or without abscess, alveolar osteitis (AO), hemorrhage, periodontal pocket formation (CAL), hematoma, osteomyelitis, prolonged pain or trismus (\>1week) or devitalization of neighboring teeth. Moreover neurosensory deficiency, bone fracture, oro-antral communication and hematoma can occur.
For dental implants: loss of implant, exposure or rejection of biomaterial/transplant material and loss of cover screw are postoperative complications.
