    (Kathmandu University, 2017) Rokaya, D; Suttagul, K; Karki, S; Rokaya, N; Seriwatanachai, D; Humagain, M
    ABSTRACT Background Understanding post-earthquake oral health indicators is essential for developing oral health interventions of the victims. Presumably, due to a geographic difficulty, there has been no investigation to reveal the oral health status of individuals after the Gorkha earthquake in Nepal. Objective The main objective was to determine the oral health and practice of Nepalese affected by earthquake in April-May, 2015. Method The epidemiological cross sectional study was done at 5 different districts (Sindhupalchok, Dadhing, Bhaktapur, Kathmandu and Kavre) of Nepal from September till November, 2015. Altogether 500 subjects aged form 16 to 80 years of age living in the transitional shelters community were included in earthquake- affected areas. Different parameters were studied from past and present medical and dental problems, habits, oral hygiene habits. DMFT, gingival index, periodontal index were studied and correlation was studied among them. Result It shows that 98% of the participants had plaque and 96.4% of the participants had calculus. Mean decayed was 9, mean missing was 4 and mean filling was 1. 22.60% of the participants had score 0, 34.8% had score 1, 34% had score 2 and 8.60% had score 3 of mean gingivitis index. 10% of the participants showed score 0, 36% showed score 1, 35% showed score 2, 10.2% showed score 3 and 8.2% showed score 4 of mean periodontal index. Moreover, significant correlation was observed among DMFT index, gingival index and periodontal index (p<0.001). Conclusion The oral health care practice, oral hygiene habits, nutritional intake of the people have been affected in the earthquake affected areas. It showed high caries index, gingival index and periodontal index in earthquake affected people suggesting further efforts are needed for an oral health improvement. Data from this study may be used as basic information for oral health planning and future steps in oral health care preventive and therapeutic programs.

    Adjunctive Orthodontic Treatment with Lingual Orthodontic System
    (Kathmandu University, 2011) Kafle, D; Humagain, M; Upadhaya, C
    ABSTRACT The lingual orthodontic therapy though started in 1972, could not be popular till the beginning of 1990. In Nepal it does not have a history of more than a year. It is started in Dhulikhel Hospital for the first time in Nepal. Usually orthodontic therapy is meant for putting braces on the labial surface of the teeth which is called labial orthodontic system. Lingual orthodontic system is a purely invisible kind of orthodontic therapy in which braces are placed behind the teeth. The advantages of lingual orthodontic therapy are: invisibility, better biomechanics and improved patient compliance. On the other hand it is difficult to master and costlier than labial orthodontics. We have presented six adjunctive orthodontic cases treated by lingual system with the same end result comparable to labial orthodontic system. KEY WORDS invisible, labial ,lingual, orthodontics

    Analysis of mammographic findings in a tertiary care hospital of Nepal
    (Institute of Medicine, 2015) Humagain, M; Paudel, S
    Abstract Introduction: Mammography is commonly the first line imaging procedure in screening of breast cancer in women. It is also commonly used as diagnostic test in the assessment or characterization of palpable breast mass along with ultrasonography. The purpose of our study was to assess the mammographic findings in women undergoing screening and diagnostic mammography. Methods: This was a prospective cross sectional study analyzing the outcomes of 497 consecutive screen-film mammographic examinations, 369 (74.2%) diagnostic and 128 (25.8%) screening, performed in female patients from 4th July 2012 to 15th October 2012 in Tribhuvan University Teaching Hospital. Analysis was based on the final assessment report of mammogram reviewed by the experienced radiologists following Breast Imaging Reporting and Data System (BI-RADS) classification. BI-RADS score 4, 5 and 6 were considered as positive, BI-RADS score 1, 2 and 3 were considered as negative and BI-RADS score 0 was considered inconclusive requiring additional imaging. Results: The mean age of women was 46.3 years (range 26-83 years). Among 369 cases of diagnostic mammograms 300 (81.3%) were negative, 27 (5.4%) were positive and rest 42 (8.4%) were inconclusive. Among 128 cases of screening mammograms, 117 (91.4%) were negative, 11 (8.6%) were inconclusive and none of them were positive. Among total (497) numbers of mammographic examinations, 417 (84%) were negative, 27 (5.4%) were positive and 53 (10.6%) were inconclusive. BI-RADS 1 was the most common reported finding comprising 26.8% in diagnostic and 12.1% in screening group. Conclusion: Analysis of diagnostic mammography examinations yields different results compared with those of screening examinations, including different patient demographics; higher number of positive findings; and possibly higher cancer detection rates. Diagnostic and screening data should be segregated during record keeping and analysis of combined results should be based on known differences between diagnostic and screening outcomes.

    (Institute of Medicine, 2017) Yadav, RR; Ansari, MA; Humagain, M; Mishra, D
    Abstract Introduction: Paranasal sinuses are a group of air filled spaces developed as an expansion of the nasal cavities, eroding the adjacent bone structures. Conventional radiology does not permit a detailed study of anatomical variations of nose and paranasal sinuses. Currently, MDCT scanning is the standard imaging modality in the evaluation of the paranasal sinuses and anatomical variations. Methodology: A cross-sectional hospital based study of 128 patients referred for CT scan of PNS was conducted from October 2015 to February 2016. CT scan was done in 128 slice Siemens Somatom Definition AS+ CT scanner machine applying standard protocol set by the department of radiology and imaging, Tribhuvan University Teaching Hospital, Maharajgunj. The images were evaluated for presence of any anatomical variants in paranasal sinuses. Results: The absolute frequency of anatomical variations are Agger Nasi cell (75.8%) and DNS (68%) along with Concha Bullosa (35.9%), Paradoxical middle turbinate (26.6%), Haller’s cell (15.7%) and Onodi cell (18.8%). In this study the most frequent type of olfactory fossa was Keros type 2 (63.3%). The typical orientation of uncinate process was found in both sides 199 (77.73%) whereas medial deviation in left side (20.3%) and right side was (18.8%) along with lateral deviation in left side was (3.9%) and right side was found in (1.6%) only. Conclusion: Anatomical variations of nose and paranasal sinuses are best depicted on MDCT scan of PNS on coronal plane with thin slice (3.0 mm) section along with bone algorithm. Agger nasi cell is the commonest anatomical variation (75.8%) followed by DNS, Concha bullosa, Paradoxical middle turbinate, Onodi cells and Haller’s cells.

    (Kathmandu University, 2024) Thapa, S; Humagain, M; Lamichhane, S; Subedi, G; Rijal, AH
    ABSTRACT In this era, role of esthetic in dentistry has been an evolving concern. One of the major concern is the hyperpigmented gingiva in patients with high smile line or excessive gingival display. This varies in different individuals and is assumed to be dependent on cutaneous pigmentation. Therefore, there are various methods of depigmentation. Hereby, is a case report of depigmentation done on upper anterior gingival region and comparing the output and patient response where half of the segment was done by using scalpel and the other half by ceramic bur with a follow up of three months. And this report concludes that ceramic bur has more advantages over scalpel technique. KEY WORDS Depigmentation, Esthetics, Soft tissue trimming ceramic bur

    Assessment of Periodontal Status of the People in Chepang Hill Tract of Nepal: A Cross Sectional Study
    (Kathmandu University, 2018) Humagain, M; Adhikari, S
    ABSTRACT Background Periodontal disease is one of the common oral and dental disease globally. The main etiology of periodontal disease is microbial plaque. However, it shares many common etiological factors with other chronic diseases. The Chepang are an indigenous Tibeto- Burman people group numbering around fifty-two thousand mainly inhabiting the rugged ridges of the Mahabharat mountain range of central Nepal. They are the tribes with different food habit, religion and culture. Till date no studies has been conducted about the periodontal and oral health status of the Chepang people. Objective To determine the prevalence of periodontitis in adult Chepang population so that knowing about its prevalence and distribution, besides serving as a demographic tool, will also help in having overview about the need for providing proper oral health care and awareness programs and initiatives aimed at reducing the disease prevalence in this indigenous group. Method The study was conducted among the adult (21 to 70 years) Chepang of Chitwan district. It was the cross sectional study with the random sampling technique. Modified Community Periodontal Index (CPI) and loss of attachment were used to record the periodontal status of all 308 sampled population. Result Out of 308 sampled participants 179 were male and 129 were female. The highest number of participants were from 41 to 50 years old (38.31%). 57.14% adult Chepang brushes their teeth once daily and 31.49% brushes twice daily and 1.30% of them had never brushes their teeth. 36.36% had loss of attachment of 4-5 mm without any significant gender difference. 6.17% of the study population had severe form of periodontitis with ≥ 12 mm of attachment loss. Calculus deposit was abundant in 57.79% of the study sample, and 25.64% shows pocket depth of 4 to 5 mm. Loss of attachment and CPI score is found to be increased with increasing age. Conclusion Result of this study reveals the presence of periodontal problems in adult Chepang population. Higher calculus with attachment loss and pocket depth were the major problems seen in this community. This highlights the necessity of implementation of more preventive program in this specific targeted population. KEY WORDS Chepang, Community, Periodontal, Prevalence

    Capillary Haemangioma of Gingiva - A Rare Lesion
    (Kathmandu University, 2023) Manohar, B; Meena, V; Metgud, R; Bhuvaneshwari, S; Humagain, M
    ABSTRACT Capillary Haemangioma is a benign vascular tumour characterized by proliferation of blood vessels with a very striking similarity to pyogenic granuloma with a predilection to occur on the gingiva. Though the head and neck are the most common region of occurrence, but is considered to be rare occurring on the gingiva, intra-orally. The lesion clinically mimicked pyogenic granuloma but was histopathologically diagnosed as capillary haemangioma. It was surgically excised and followed up for 6 months without any recurrence.

    Clinico-histopathological Survey of Head and Neck Cancer at Tertiary Health Care Centre -Dhulikhel Hospital
    (Kathmandu University, 2016) Dixit, S; Upadhyaya, C; Humagain, M; Srii, R; Marla, V
    ABSTRACT Background Head and neck is one of the most prevalent site for cancers along with lungs, cervix, breast and stomach. Hospital based cancer registries required for effective evaluation of diagnosis and management of cancer is inadequate in Nepal. Cancer registry system established by WHO is acquired by seven major hospitals in our country. However, data from tertiary health care centres like ours remain undocumented. Objective The objective of this study is to perform retrospective analysis of clinico- histopathological types of head and neck lesions which were eventually diagnosed as cancer in Dhulikel Hospital, a tertiary health care centre of Central East Nepal. Method Data regarding head and neck lesions diagnosed as cancer (January 2001- December 2014) were extracted from the archives of Department of General Pathology. These cases were categorised according to demographic profile, site of cancer and histological diagnosis. Result A total of 240 cases matched the inclusion criteria and were selected for this study. Male: Female ratio of 1.3:1 with a mean age of 52 years (52.82±1.8) was found. Two hundred and two (84.16%) patients were diagnosed with carcinoma, 31 (15%) with lymphoma, 3 (1.25%) with melanoma, 2(0.83%) with small round cell tumor and 2 (0.83%) with sarcoma. The most common histological types of carcinoma seen were Squamous cell carcinoma (138 cases; 57.5%) followed by papillary carcinoma (26 cases; 10.8%). Among the lymphomas Non-Hodgkin’s lymphoma (21 cases; 8.75%) was the most predominant type. The most common site of presentation was oral cavity (60 cases; 25%) followed by skin (36 cases; 15%), thyroid (32 cases; 13.33%) and oesophagus (27 cases; 11.25%). Metastasis to cervical lymph node was found in 39 cases (16.25%). Conclusion Based on these finding, it was observed that Squamous cell carcinoma was the most common type followed by different epithelial and mesenchymal malignancies in head and neck region. The results revealed by this study will provide useful information for planning the health care policies about cancer in Nepal and will be more effective and helpful to the patients of remote areas.

    Clinicopathological Analysis of Oral Lesions - A hospital based retrospective study
    (Kathmandu University, 2019) Poudel, P; Upadhyaya, C; Humagain, M; Srii, R; Chaurasia, N; Dulal, S
    ABSTRACT Background Proper diagnosis plays a key role that determines treatment and prognosis of the disease. To give appropriate clinical diagnosis, clinicians must be well aware of the presentation and demographic information of the lesion including the rare ones. Histopathology is still considered as gold standard in diagnostic pathology but final diagnosis becomes difficult unless detailed clinical and radiological descriptions are given. Hence an interdisciplinary approach is needed which requires correlation between both clinical and pathological details. Objective To analyze the clinicopathological details of all the oral lesions diagnosed in Dhulikhel hospital within the period of two years and to assess the concordance between clinical and histopathological diagnosis of these lesions. Method Laboratory record file of all the oral lesions diagnosed between January 2016 to December 2017 were retrieved from the department archives and the data were collected. The extracted data were analyzed using SPSS version 23.0. Result A total of 237 cases were analysed in the present study. Odontogenic cysts were the most common category followed by benign lesions. However considering the individual lesion, mucocele was the commonest lesion followed by squamous cell carcinoma. Total concordance between clinical and histopathologic diagnosis was found in 56.5% cases. The most clinicopathological agreement was seen for benign lesions followed by malignant lesions. Conclusion Mucocele and oral squamous cell carcinoma are the two most common lesions found among the patients visiting our hospital. The cases of oral squamous cell carcinoma are on a rise with each subsequent year. At present, though it is the second most common entity, it can be hypothesized that it may be higher up on the list. Therefore, oral healthcare awareness is paramount and this may be one of the best ways to reduce the oral cancer incidence rates and lowering the healthcare management burden.

    Co-relation between Non-specific Knee Joint Pain and Osteoarthritis
    (Institute of Medicine, 2016) Humagain, M; Paudel, S; Hengwoju, S
    Abstract Introduction: Osteoarthritis (OA) is a degenerative joint disease. Pain is the worst and most frequent problem in OA patients that leads to disability. The rate of knee joint pain has been found to be correlated with OA in many studies. The association of knee pain with OA differs by gender, with advancing age and nature of occupations. Knee radiograph is preferred by most of the physicians for the initial assessment of the knee joint pain. This study was carried out to see the relation between knee joint pain and OA along with age, sex and occupation. Methods: In this prospective cross-sectional study, knee radiographs of 200 patients performed in the Radiology Department of T.U. Teaching Hospital for nonspecific knee joint pain were reviewed. Pain was considered as non specific pain when there was no history of trauma or any known disease affecting the joint and no significant abnormality related to any disease entity was found during clinical examination. The study was conducted over a period of three months between July to September 2015. The proforma was filled and then collected data were analyzed using SPSS software to show the relation between knee joint pain and OA. Results: Among total of 200 knee x-rays, 63% (126) were female and 37% (74) were male. The highest number of population was in the age group of 50-59 year, which comprised 26% of total population and lowest population was in >80 year group comprising 0.5% of total population. Housewives were highest in number comprising 39.5% (79) followed by farmer 19% (38), physical worker 15.5% (31), people in service 12.5% (25), business 7.5% (15) and student 6% (12). Of the total population, 59% (118) had radiographic features of OA changes. Most affected people were older than 50 years and all patients older than 70 years had OA changes. No OA was seen in people younger than 20 years. Highest percentage of OA was found in housewives accounting 51.7% followed by farmers (18.6%) and business people (4.2%. No OA was found in students involved in the study. Conclusion: The study demonstrated that the occurrence of OA is more common finding in population with non-specific knee joint pain. OA is more common in females and population of age ≥50 years. OA is most common in housewives and least in students. Keywords: knee, pain, osteoarthritis, x-ray

    (Kathmandu University, 2021) Dawadi, A; Humagain, M; Sapkota, B; Subba, M; Neupane, M; Lamichhane, S
    ABSTRACT For obtaining adequate retention for restoring cases like subgingival caries or extensive caries that shortens the tooth, short clinical crown, and fractures, it is usually necessary to disclose more tooth structure. Crown lengthening procedure is done to increase the clinical crown length for restorative or esthetic reasons without breaching the biologic width. These procedures are also utilized to improve the appearance and retention of restorations placed within the esthetic zone. We report a case of crown lengthening surgery with an internal bevel gingivectomy which was done in our department without compromising tooth support and esthetics.

    Dental Negligence: Accidental Administration of Formalin Instead of Local Anesthetic
    (Kathmandu University, 2021) Manohar, B; Ranjitha, RS; Bhuvaneshwari, S; Awasthi, R; Humagain, M
    ABSTRACT A solution like formalin used as a fixative has to be handled with lot of care and needs to be stored with utmost care. Negligence on part of the dental professional by accidentally injecting formalin instead of the local anesthetic can lead to permanent tissue damage and also may induce a life threatening situation. The operating dentist injected formalin accidentally instead of the local anesthetic and the patient experienced severe pain and burning sensation. The general practice of formalin being stored in the local anesthetic bottles and being assisted by untrained assistant is the most common reason for mishaps to happen. The dentist operating should be careful and aware of the drugs and chemicals being available in the operatory and re-check the solution being injected in the patient as to not land up in complications because of the negligence.

    Efficacy of Four Herbal Extracts on Actinobacillus Actinomycetemcomitans and Prophyromonas Gingivalis: an in vitro microbiological study
    (Kathmandu University, 2024) Kafle, D; Humagain, M; Luintel, S; Karki, A; Lamichhane, J
    ABSTRACT Background Periodontitis is probably one of the most common diseases occurring worldwide caused by interaction of anaerobic and aerobic microorganism found in dental plaque. Medicinal plant extracts, rooted in traditions like Ayurveda, provide a promising avenue for antimicrobial study against periodontal pathogens. Objective To assess the antimicrobial properties of extracts from indigenous medicinal plants against Actinobacillus actinomycetemcomitans (ATCC: 29522) and Prophyromonas gingivalis (ATCC: 33277), two potent periodontal pathogens. Method Four medicinal plants grown in different altitudes of Nepal were selected Tejpatta (Cinnamomum tamala), Vajradanti (Barleria prionitis), Danti (Baliospermum montanum), and Ghotape (Centella asiatica), henceforth denoted as GP1, GP2, GP3 and GP4 respectively), and their extracts were prepared using standard biochemical protocol. Phytochemical composition was analyzed through Fourier Transform Infrared Spectroscopy (FTIR) and Liquid Chromatography-Mass Spectrometry (LC- MS). Antimicrobial activity against A. actinomycetemcomitans and P. gingivalis was assessed through MIC, MBC, and zone of inhibition assays. Result All of the four extracts were found to have antimicrobial activities against A. actinomycetemcomitans and P. gingivitis. The dry extract of Tejpatta was the most effective for zone of inhibition with minimal concentration of 187.5 μg/ml for MIC and 750 μg/ml for MBC. Additionally, Vajradanti and Danti were also effective against P gingivalis with the highest zone of inhibition (25 mm) followed by the dry extract of Tejpatta (22 mm) at a concentration of 100 mg/ml. Conclusion Phytochemical analysis revealed diverse chemical compounds in the plant extracts, indicating a potential therapeutic value. Among the four herbal plants, GP1 (Cinnamomum tamala) was found as the most potent against A. actinomycetemcomitans. GP2 (Barleria prionitis), GP3 (Baliospermum montanum) and GP1 (Cinnamomum tamala) displayed significant inhibition zones against both the periodontal pathogens A. actinomycetemcomitans and P gingivalis.

    Evaluation of arterial phase images with 90vp in multiphase abdominal CT scan
    (Institute of Medicine, 2017) Chapagain, KM; Humagain, M; Lohani, B; Shrestha, SL; Thapa, N
    Abstract Introduction: CT scan of abdomen is usually performed in 120-140 kVp and such high ranges of kilovoltage in all phases will increases the radiation dose many fold. The purpose of the study was to qualitatively and quantitatively assess image quality with low kVp in arterial phase of examination of multiphasic abdominal CT study. Methods: A prospective cross-sectional study was done in 206 participants of age 18 to 88 years who were undergoing multiphase CT studies of the abdomen in Neusoft 16 detector MDCT. After performing non contrast scan, arterial phase study of limited region of abdomen (diaphragm to infrarenal margins) was obtained with 90 kVp. The portovenous phase scan with standard protocol was obtained (120kVp). All other scanning parameters were kept same for two phases. Images were rated on 5 point scale (1-worst, 2-Suboptimal, 3-adequate,4-very good,5-excellent) based on visualization of boundaries, anatomical details of the organs and visualization of noise and artifact by two radiologists. Patient weight, abdominal circumference (AC), height and BMI were recorded and correlated with the image quality score. Statistical analysis was done with Wilcoxon’s signed ranks test k test and descriptive analysis. Results: Overall the image quality of portovenous phase was significantly better (p<0.005) than low kVp arterial phase. Image quality score correlated best with abdominal circumference in standard dose technique (r=0.54) and patient weight in reduced dose technique (r=0.44). Arterial phase scanning had acceptable image quality score for patient weight of <60 kg, AC <80cm and BMI<25 kg/m2. The CTDIvol was 7.71 with reduced kVp protocol and 20.02 with standard resulting significant reduction in radiation dose of about 61% Conclusions: The image quality of arterial phase images with 90kVp tube potential is acceptable in thin and average built patients. Hence reduction in radiation dose is possible if arterial phase scanning is done with reduced kVp except in patients with large anthropometric parameters.

    ABSTRACT Background The size, proportion and gingival zenith position of maxillary anterior teeth plays in the anterior teeth esthetics. Objective To compare the gingival zenith positions and levels between male and female in right and left side as an esthetic parameter. Method Impression of the maxillary arch was made in each participant with irreversible hydrocolloid, and dental cast was made with dental stone type IV. Two clinical parameters were evaluated: (1) the gingival zenith position (GZP) from the vertical bisected midline along the long axis of each individual maxillary anterior tooth; and (2) the gingival zenith level (GZL) of the lateral incisors in an apical-coronal direction relative to the gingival line joining the tangents of the GZP of the adjacent central incisor and canine teeth under healthy conditions. Statistical analyses were conducted using SPSS with the level of significance (α) = 0.05. Descriptive statistics was done and Independent t-test was used to compare the GZP and GZL between male and female. Result In male, the gingival zenith position for right side central, lateral and canine were 1.05 mm, 0.57 mm and 0.14 mm, and in left side were 1.02 mm, 0.53 mm, 0.15 mm. In female, the gingival zenith position for right side central, lateral and canine were 0.99 mm, 0.48 mm and 0.15 mm, and in left side were 0.94 mm, 0.44 mm and 0.14 mm. The gingival zenith position was significantly different between male and female for both lateral incisors. In addition, significantly different was found for the lateral incisor between right and left side. In male, the gingival zenith level of right and left lateral incisors 0.74 mm and 0.71 mm. In female, the gingival zenith level of right and left lateral incisors 0.76 mm and 0.72 mm. No significant difference was found between male and female for the gingival zenith level of right and left lateral incisors. Conclusion The GZP and GZL obtained from this study can be clinically applied to reestablish the GZP of the maxillary anterior teeth during periodontal surgery; crown lengthening or root coverage procedures.

    (Kathmandu University, 2015) Rokaya, D; Kitisubkanchana, J; Wonglamsam, A; Santiwong, P; Srithavaj, T; Humagain, M
    ABSTRACT Background Lots of studies on maxillary anterior teeth proportions have been studied in different populations in various countries, but no studies have been conducted in Nepal on the esthetic maxillary anterior teeth proportions. Objective The study was done to investigate the maxillary anterior teeth proportions in a Nepalese population. Teeth proportions in the total population were compared with golden proportion (GP) and golden standard (GS). Method A total of 150 Nepalese subjects were divided in three facial types; broad, average and narrow group. Maxillary anterior teeth were measured from dental casts using digital calipers. The perceived width ratios of lateral to central incisor (LI/CI) and canine to lateral incisor (CN/LI), ratios of mean central incisor length to 2 central incisor widths (CIL/2CIW), and actual width to length ratios (WLRs) (%) were calculated in each facial type and compared. Mean LI/CI, CN/LI and CIL/2CIW in total population were calculated and compared with GP (0.618), and mean WLRs in the total population were compared with GS (80%). All teeth proportions were compared among three facial types. One-sample t-test and one-way ANOVA were performed to analyze the data (α = 0.05). Result The LI/CI, CN/LI, CIL/2CIW and WLRs in three facial types showed no significant difference. The LI/CI, CN/LI and CIL/2CIW in the total population were 66%, 70% and 55% respectively, and were significantly different from GP. The WLRs for CI, LI and CN in the total population were 90%, 86% and 89% respectively and significantly differed from GS. These values were considered to constitute the Nepalese Esthetic Dental (NED) proportion. Conclusion No significant difference of maxillary anterior teeth proportions were observed among three facial types. Teeth proportions in the total population significantly differed from GP and GS. We propose the NED proportion as a guideline for dental treatment in the maxillary anterior region in Nepalese populations.

    Periodontal infections and cardiovascular disease: Is it a mere association?
    (Kathmandu University, 2006) Humagain, M; Nayak, DG; Uppoor, AS
    The oral cavity is a major site of chronic infection and inflammation, particularly periodontal or chronic gum diseases. In recent years there has been increasing interest in the “periodontal systemic connection” between periodontal health parameters and risks of cardiovascular disease. Given that poor oral health and cardiovascular disease are major worldwide health problems, their association are potentially important. The article summarizes the evidences from epidemiologic studies and studies that focused on potential contributing mechanisms to provide an insight of this association
