Background: The aim of this study is to compare the effect of mesial and distal adjacent gingival phenotypes of the tooth or teeth region of free gingival graft (FGG) on the shrinkage ratio of graft at 6 months postoperatively.Methods: Thirty-one patients with inadequate keratinized gingival width (KGW) around mandibular incisors were included in this study. The phenotype of the mesial and distal terminal teeth was evaluated by the probe transparency method and keratinized gingival thickness measurements; study groups were divided as thick and thin phenotype. The plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL) and recession height (GRH), recession width (GRW) and KGW measurements were recorded at baseline and sixth month. Vertical dimension of graft (VDG), horizontal dimension of graft (HDG), recipient area horizontal width (RAHW), recipient area vertical depth (RAVD) were recorded during surgery. The shrinkage ratio was calculated with a Java-based analysis program. Results:There was no significant difference in the clinical and surgical measurements between the groups. KGW mean values for both of adjacent teeth increased at 6th month compared to baseline but there was no difference between the groups at 6 months. GRH value has decreased significantly in thick phenotype group at the 6th month. The shrinkage ratio was found 23.14 ± 12.21% and 17.76 ± 11.05% in the thin and thick phenotype group, respectively. The difference between the groups was not statistically significant (p = 0.210). Conclusion:The phenotype of the adjacent teeth has a similar impact on FGG shrinkage ratio at the sixth month. Thick phenotype of adjacent teeth seems to be more supportive for root coverage.

Periodontitis, konak-bakteri arasındaki etkileşimler sonucunda ortaya çıkan periodonsiyumun kronik yıkımla karakterize hastalığıdır. Oral hijyen ve periodontal sağlığın KOAH oluşumunda ve/veya ilerlemesinde etkili olabileceği pek çok çalışmada belirtilmiştir. Bununla birlikte respiratuar patojenlerin de oral kavitedeki kolonizasyonunun respiratuar hastalıkların gelişimi için bir risk faktörü olması ve periodontal tedavilerin de respiratuar hastalıkların insidansı ve şiddeti üzerine olan etkisi araştırılmaktadır. Bu derlemenin amacı kronik obstruktif akciğer hastalığı (KOAH) ile zayıf oral hijyen, mikrobiyal dental plak ve periodontal hastalıklar arasındaki potansiyel ilişkinin değerlendirilmesidir. Periodontal sağlık ile KOAH arasındaki ilişkinin yapısı halen tam olarak anlaşılamamış olmakla birlikte; tıp ve diş hekimliğinin ortak çalışmaları ile aradaki bu bağlantının mekanizması daha iyi anlaşılarak hastaların yaşam kalitelerinde iyileşme elde edilebilir. Anahtar Kelimeler: KOAH, periodontitis, dental plak, ağız hijyeni ABSTRACT Periodontitis is characterized by the destruction of the periodontium that occurs as a result of interactions between the host and the bacteria. Several recent studies provide evidence that oral hygiene and periodontal health may influence the initiation and/or progression of COPD. However, the oral cavity colonization of respiratory pathogens may be a risk factor for development of respiratory diseases and the effects of periodontal treatments on the incidence and severity of respiratory diseases are under investigation. This paper's goal is to review the potential relationship between chronic obstructive pulmonary disease (COPD) and poor oral hygiene, microbial dental plaque and periodontal disease. The link between periodontal disease and COPD remains unclear. However, we believe that with cooperation between medicine and dentistry, the nature of this connection can be better understood and improvement in the quality of life of patients can be achieved.
