Periodontal disease Oral bacterial inflammation

  1. 2. Periodontal disease <ul><li>Oral bacterial inflammation </li></ul><ul><li>Irreversible attachment loss </li></ul><ul><li>Bone destruction </li></ul><ul><li>Tooth loss </li></ul><ul><li>Smoking, socioeconomic background, diabetes, genetic, attitude toward health, supragingival plaque control </li></ul>
  2. 3. <ul><li>Women are generally in better health than men, and they have a lower mortality rate </li></ul><ul><li>Women were in better periodontal health, but they had fewer teeth than their male counterparts. </li></ul>
  3. 4. Hypothesis I <ul><li>“ Teeth are very seldom lost; teeth are extracted by dentists.” </li></ul><ul><li>Scheutz F, Poulsen S. A tooth per child? Lancet 1998;352:1387 . </li></ul><ul><li>Whether the frequency of dental appointments could be a reason for the gender-related difference. </li></ul><ul><li>Women take better care of their health and therefore visit the dentist more frequently then man. </li></ul>
  4. 5. Hypothesis II <ul><li>“ For each child born, one tooth is lost.” </li></ul><ul><li>Christensen K, Gaist D, Jeune B, Vaupel JW. </li></ul><ul><li>A tooth per child? Lancet 1998;352:204 . </li></ul><ul><li>Parity is associated with tooth loss and dental disease in US women. </li></ul><ul><li>Russell SL, Yaffee R, Ickovics J. Exploring pathways between parity and dental health in US women </li></ul>
  5. 6. Hypothesis III <ul><li>Women are at high risk of osteoporosis than men, especially in older age. </li></ul><ul><li>It is assumed that there are associations between osteoporosis, periodontal disease, alveolar bone loss, and tooth loss. </li></ul>
  6. 7. (SHIP)
  7. 8. Hypothesis I <ul><li>Female participants reported a higher frequency of dental appointments than their male counterparts. </li></ul><ul><li>The frequency of dental visits during the previous 12 months was negatively correlated with the number of teeth In the age groups of the 20- to 60-year-old participants, regardless of sexes. </li></ul>
  8. 9. Hypothesis I <ul><li>In participants older than 60 years, there was a positive correlation (P < 0.0001). The more frequent dental appointments that participants in this age group had, the more teeth they had. </li></ul><ul><li>hypothesis I is to be rejected. </li></ul>
  9. 10. Hypothesis II nulliparous One or more children 1. With every child born, the number of teeth was reduced by nearly one tooth 2. The relationship was greater in the lowest income class and was much attenuated in the group of the highest social level. 3. Hypothesis II is to be accepted.
  10. 11. Hypothesis III Men>50 y/o Women HT(-) Women HT(+) <ul><li>Bone density was not assessed. </li></ul><ul><li>Estimated bone turnover by excretion of urinary deoxypyridinoline collagen </li></ul><ul><li>Only those women who do not use estrogens after menopause have fewer teeth than men; women using estrogen even have more teeth than men. </li></ul><ul><li>Hypothesis III is to be accepted. </li></ul>
  11. 12. <ul><li>The results of this analysis support the assumption that giving birth to children is associated with an increased risk of tooth loss. </li></ul><ul><li>However, this association was detected only in participants with a low socioeconomic status of the husband or low education level. </li></ul>
  12. 13. <ul><li>Pregnancy-associated gingivitis seems to have some impact on long-term dental health, even though this gingivitis is considered a temporary disturbance </li></ul><ul><li>Pregnancy is characterized by high bone turnover with resorption and a significant decrease in bone mineral density </li></ul>
  13. 14. <ul><li>Individuals with osteoporosis may be at an increased risk of the manifestations of oral osteoporosis although such a risk is not definitively proved. </li></ul><ul><li>There is the possibility that the lack of estrogen influences the activities of bone cells and immune cells that the progression of alveolar bone loss will be enhanced. </li></ul><ul><li>Alveolar bone loss is a strong and independent predictor of incident tooth loss in post-menopausal women. Conversely, the number of teeth is no predictor of bone density. </li></ul>
  14. 15. <ul><li>Bone remodeling processes and decreasing bone mineral density affect tooth retention during pregnancy and later, after menopause. The association between the number of children born (and also of pregnancies) and collagen turnover confirms such findings. </li></ul><ul><li>These effects may explain the paradox of having fewer teeth with better periodontal health. </li></ul>
