Influence of sex hormone levels on gingival enlargement in adolescent patients undergoing fixed orthodontic therapy: A pilot study

BACKGROUND: Sex hormones may be a modifying factor in the periodontal disease pathogenesis. AIM: The association between gingival enlargement and sex hormone levels in adolescent patients undergoing fixed orthodontic therapy needs to be determined. SETTINGS AND DESIGN: This study was conducted in the Department of Periodontology in association with the Department of Orthodontics, Yenepoya Dental College, Yenepoya University, Mangaluru. MATERIALS AND METHODS: A pilot study was conducted on 21 adolescent patients between the age group of 13–19 years, who had undergone fixed orthodontic therapy for at least 3 months. Apicocoronally, the gingival enlargement was assessed by the index described by Miller and Damm. Miranda and Brunet index was used to assess gingival overgrowth in the buccal–lingual direction in the interdental papilla. Furthermore, the patients were assigned to two groups - Group 1-GE and Group 2-non-GE. Sex hormones assessed were estradiol and progesterone in females and testosterone in males in both groups. RESULTS: 57.1% of the study population had enlargement of the gingiva. The mean plaque score was 0.59 and 0.56, respectively, in both groups. A statistically significant relationship was found between estradiol and testosterone levels with gingival enlargement. However, a significant relationship was not obtained for progesterone levels with the gingival enlargement. CONCLUSION: Direct correlation between estradiol, testosterone, and gingival enlargement was seen.
