Introduction: The effects of swimming on dimensions of dentition have never been explored in orthodontics. Objective: To find out the effects of swimming on vertical and transverse dimensions of dentition. Study design: A cross sectional study. Setting: Department of Orthodontics, Dental Section-Faisalabad Medical University & de’Mont, Lahore. Duration of study: 18 months from 10-2-2017 to 10-8-2018. Sample size: The calculated sample size was 100 patients. Sampling technique: Purposive sampling technique. Data collection procedure: Present study consisted of comparison of 50 swimmers with 50 non-swimmer controls. Plaster models were obtained for the evaluation of overbite, intermolar width and crossbites. Results: Insignificant differences were found in overbite (P =0.65) between swimmer and the control group. However, control subjects were having significantly increased frequency of crossbites. Conclusion: Swimming was not found to influence the vertical dimensions of dentition; however, it might decrease a chance of developing crossbites.
