Aim: This questionnaire-based study evaluated the attitude and knowledge of periodontal regeneration procedures by Kuwaiti dentists. Furthermore, the study aimed to validate the results of a previous cross-sectional postal questionnaire conducted by Siaili et al., , based on UK-based dentists with a specialty or a special interest in periodontology. Material and Methods: A cross-sectional questionnaire was completed involving 31 questionnaires and conducted from Kuwaiti dentists by e-mail (pilot phase) together with the 98 Kuwaiti-based dentists (main phase). The questionnaire consisted of 21 questions involving both multiple choices answers and open-ended or dichotomous options and was divided in two broad sections addressing: 1) the general profile of dentists and 2) their preferences regarding the management of intrabony, interradicular and marginal tissue recession defects together with their opinions on smoking and use of antibiotics in regeneration procedures. Data were analyzed and entered using SPSS version 21 (IBM UK, Guildford) and frequency tables constructed, any associations between the variables were tested at the 5% level significance (p ≤ 0.05). Results: Kuwaiti Dentists (M 90: F 39; mean age: 35.7 ± 7.2 years) completed 129 questionnaires. The use of guided tissue regeneration procedures with absorbable membranes was the most popular option for the regeneration of intrabony defects. The use of connective tissue grafts and coronally advanced flaps were the most frequently chosen treatment modalities for root coverage procedures. A reasonable level of participants using special flap techniques for regenerative procedures was also reported. 90.4% of respondents prescribed antibiotics of which Amoxillicin /Metronidazole (33.6%) was the most reported. 73.4% of the participants did not consider smoking to be a contraindication for periodontal regeneration procedures. Conclusion: The results from the present study would suggest that Kuwaiti dentists were aware of current innovations in periodontal regeneration, however there were conflicting responses regarding the exclusion criteria of smokers prior to the regenerative procedure and the prescription of post-operative antibiotics following regenerative procedures compared with the evidence from the published literature. The use animal-derived materials for regenerative procedures was not acceptable to most of the participants in the study.
