 This purpose of this database is to collect, store and use appropriately derived data from routine patient care in a specialist dental practice. Comprehensive observational data will be gathered, systematically organised and be continuously updated. This data will be used to evaluate treatment outcomes and identify areas for improvement. This will contribute to the existing evidence base to validate new and current clinical concepts in dentistry. Patient consent will be sought for this, and all data extracted from patient notes will be stored and used anonymously. Use of the Oral Health Impact Profile OHIP -14 questionnaire pre and post treatment will be used to assess patient satisfaction with outcomes.
