위염 및 위암 등의 발생과 관련되어 있는 Helicobacter pylori(H. pylori)는 구강의 치태와 타액에서 주로 발견이 된다. 유년시절 동안 주로 감염되는 것으로 알려져 있지만 감염경로는 불분명하다. 구강이 H. pylori의 두 번째 서식지로서 전염경로 및 위장내 H. pylori의 제균 후 재감염에 중요한 영향을 끼칠 수 있는지는 논쟁이 되고 있다. 따라서 본 저자는 문헌고찰을 통하여 구강 내에 존재하는 H. pylori에 관하여 알아보고자 하였다. 위장에 존재하는 H. pylori는 위인두반사나 구토에 의해 구강 내 발현될 수도 있으나, 구강과 위의 감염은 서로 관련성이 없는 것으로 보고되고 있다. 진단방법으로는 혈청학적검사, 요소호기검사, 중합효소연쇄반응(polymerase chain reaction: PCR)방법, Urease검사, 조직검사 등이 있으나, 타액과 치태에서는 nested PCR 방법이 주로 추천되어 진다. 구강 내 감염율은 다양하게 나타나며, 치과질환과의 연관성은 없는 것으로 사료된다. 그러나 치주질환 환자의 구강 내에서 발현율은 높게 나타나므로, 주의가 요구되며 향균 구강세척제의 사용이 권유된다. 결과적으로 구강 내 H. pylori는 정상세균총으로 사료되며, 향후 구강내 H. pylori에 관한 추가적인 많은 연구가 필요하리라 사료된다.

Purpose: Triphala is a combination of three medicinal plants, extensively used in Ayurveda since ancient times. Triphala mouthwash is used in the treatment of periodontal diseases because of its antimicrobial and antioxidant properties. The aim of this study is to compare the efficacy of triphala mouthwash with 0.2% chlorhexidine in hospitalized periodontal disease patients. Methods: In this double-blind, randomized, multicenter clinical trial, 120 patients were equally divided into three groups. Patients in group A were advised to rinse their mouths with 10 mL of distilled water, group B with 0.2% chlorhexidine, and group C with triphala mouthwash for 1 minute twice daily for two weeks. The plaque index (PI) and the gingival index (GI) were recorded on the first and the fifteenth day. Results: There was no significant difference when the efficacy of triphala was compared with 0.2% chlorhexidine in hospitalized patients with periodontal disease. However, a statistically significant difference was observed in PI and GI when both group B and group C were compared with group A and also within groups B and C, after 15 days (P<0.05). Conclusions: The triphala mouthwash (herbal) is an effective antiplaque agent like 0.2% chlorhexidine. It is significantly useful in reducing plaque accumulation and gingival inflammation, thereby controlling periodontal diseases in every patient. It is also cost effective, easily available, and well tolerable with no reported side effects.

구강은 전신건강을 들여다 볼 수 있는 창문이자 많은 유해균이 들어오는 관문이기도 하다. 우리 몸에 있어서 아주 중요한 부분이다. 유전자 검사는 구강 내 세균을 검사하여 빅 데이터 AI 알고리즘 분석을 통해 우리 몸에 발생할 수 있는 전신질환까지 예측하여 예방 관리를 체계적으로 할 수 있다는 가장 큰 장점이 있다. 이에 본 논문은 연구자 가족이 직접 유전자 검사를 수행하여 결과를 도출해 보고자 한다. 본 연구는 2022년 11월 연구자 가족 4명이 서울시에 소재한 예방치과진료실 J치과의원에서 치과의사 1명, 치과위생사 1명에게 사전설명을 듣고 동의서 작성 후 구강검사와 유전자 검사를 수행하였다. 성인은 Dr.^***으로 중·초등학생은 He^***** 제품으로 유전자 검사를 하였다. 현재 우리나라에서 진행하고 있는 유전자 검사는 대상자가 피를 뽑지 않고 비교적 쉽게 접근할 수 있는 장점도 있지만, 시간, 비용 등 한계점도 있다. 그럼에도 불구하고 구강 내 미생물을 통해 전신질환을 예측할 수 있다는 점에서는 높이 평가할 부분이라고 생각한다.

Background: Although microbial infection is direct cause of periodontal disease, various environmental factors influence the disease severity. Aging is considered a risk factor for oral diseases, with the prevalence of periodontal diseases increasing with age. Moreover, senescence-associated secretory phenotype (SASP) expressed in age-related diseases is a key marker of chronic inflammation and aging phenotypes. Therefore, this study aimed to understand the relevance of senescent cells to periodontal health and disease, investigate the possibility of regulating the expression of aging- and osteolysis-related factors in gingival fibroblasts, and investigate the effect of senescence induction in gingival fibroblasts on osteoclast differentiation in mouse bone marrow-derived macrophages (BMMs). Methods: After stimulation with 400 nM hydrogen peroxidase, human gingival fibroblasts (HGFs) were examined for senescence-associated β-galactosidase. Western blot and enzyme-linked immunosorbent assays were performed to assess the expression of SASP. Osteoclast formation was assessed in BMMs using a conditioned medium (CM) from hydrogen peroxide-stimulated HGFs. Osteoclastic differentiation was investigated using tartrate-resistant acid phosphatase (TRAP) staining and activity. Data analysis was performed using SPSS version 25.0. Results: The expression of senescence-related molecules, including p53, p16, and p21, and the expression of osteolytic factors, including IL-6, IL-8, and IL-17, were found to be significantly higher in the hydrogen peroxide-stimulated HGF than in the control group. Regarding the indirect effects of senescent gingival cells, the number of osteoclasts and TRAP activity increased according to the differentiation of BMM cultured in CM. Conclusion: Our results on the of between osteolytic factors and cellular senescence in gingival fibroblast cells helped to reveal evidence of pathological aging mechanisms. Furthermore, our results suggest that the development of novel therapies that target specific SASP factors could be an effective treatment strategy for periodontal disease.

흡연은 전신뿐 아니라 구강에서 발생하는 다양한 질병의 중요한 위험 인자이며, 치과의사가 금연 치료에 참여하는 것은 개인의 전신 건강과 치주치료와 임플란트 치료 같은 치과 치료의 예후에도 큰 차이를 보여주는 것으로 알려져 있다. 흡연이 구강암과 같은 생명을 위협하는 비교적 흔치 않은 질병으로부터 경미한 구강 내 증상에 이르기까지 구강 환경에 다양한 영향성과 관련한 많은 근거가 있음에도 불구하고, 흡연과 구강건강의 관련성에 대한 환자들의 인식 수준을 조사한 연구는 적고, 금연진료에 대한 국내 치의학계의 관심과 참여는 더욱 부족하다. 그러므로 본 연구는 국내 치과 외래 환자의 흡연 양상과 치과계의 금연 진료 현황을 파악하여 금연 진료 방향을 모색해 보고자 하였다. 대한치과의사협회 문화복지부의 후원으로 전국 11개 치과대학병원의 구강내과, 구강외과 및 치주과 환자 중 825명이 니코틴 패치를 이용한 4주 금연 프로그램 및 설문에 참여하였고, 297명이 금연 설문에 참여하였다. 각 설문지 분석을 통해 각 치과대학병원의 조사 현황, 치과 외래 환자의 흡연 양상을 분석하였고, 치과에서 시행된 4주간의 금연 치료의 참여목적과 성공률을 조사하였다. 본 연구의 결과에 따르면, 흡연자는 주로 30-50대 중 장년층이 많았고, 흡연기간은 연령 증가에 비례하며, 하루 흡연량은 30대에서 가장 많았다. 금연시도는 30,40대에서 금연시도 비율이 높았고 그 기간은 대부분 1-3개월이었다. 흡연의 이유로는 스트레스 해소와 습관이 가장 높은 빈도를 보였으며 Heavy Smoking Index (HSI)는 20대가 가장 낮고 (71.4%) 60대가 가장 높았다(93.7%). 흡연 경고 문구에 대해 참가자의 68%는 금연을 떠올렸다. 구강질환(구강점막질환, 치주질환, 치아우식증)과 흡연의 관련성에 대한 실험참가자들의 인식도는 비교적 높았지만(50~68%) 금연 성공률은 일반 의과진료실에 비해 아주 낮은 결과를 보였다(22.7%). 흡연관련 질환 예방 업무에서의 치과의사의 중요성을 고려할 때, 금연치료에 치과의사들이 보다 적극적으로 참여할 수 있는 인식의 변화가 필요하다. 낮은 치료 성공율이 체계화되지 못한 진료내용 때문임을 고려할 때, 5As' 방법 등과 같은 금연관련 상담에 대한 지속적인 치과의사 교육과 환자 교육을 위한 다양한 자료의 개발을 통해 금연 성공률을 높일 수 있도록 해야 한다.

Background: Inflammatory dental diseases that occur during pregnancy can cause preterm labor and/or intrauterine growth restriction. Therefore, proactive treatment of dental diseases is necessary during pregnancy. Dexmedetomidine (DEX) is a widely used sedative in the dental field, but research on the effect of DEX on pregnancy is currently insufficient. In this study, we investigated the effects of co-treatment with DEX and lipopolysaccharide (LPS) on inflammatory responses in human amnion-derived WISH cells. Methods: Human amnion-derived WISH cells were treated with 0.001, 0.01, 0.1, and 1 ㎍/mL DEX with 1 ㎍/mL LPS for 24 h. Cytotoxicity of WISH cells was evaluated by 3-(4,5-dimethylthiazol)-2,5-diphenyltetrazolium bromide (MTT) assay. The protein expression of cyclooxygenase-2 (COX-2), prostaglandin E₂ (PGE₂), p38, and nuclear factor kappa B (NF-𝜅B) was examined by western blot analysis. The mRNA expression of pro-inflammatory cytokines such as interleukin (IL)-1𝛽 and tumor necrosis factor (TNF)-𝛼 was analyzed by real-time quantitative polymerase chain reaction. Results: Co-treatment with DEX and LPS showed no cytotoxicity in the WISH cells. The mRNA expression of IL-1𝛽 and TNF-𝛼 decreased after co-treatment with DEX and LPS. DEX and LPS co-treatment decreased the protein expression of COX-2, PGE₂, phospho-p38, and phospho-NF-𝛋B in WISH cells. Conclusion: Co-treatment with DEX and LPS suppressed the expression of COX-2 and PGE₂, as well as pro-inflammatory cytokines such as IL-1𝛽 and TNF-𝛼 in WISH cells. In addition, the anti-inflammatory effect of DEX and LPS co-treatment was mediated by the inhibition of p38/NF-𝜅B activation.
