Acta Odontol Scand 2024; 83:348-355. [PMID: 38860278 PMCID: PMC11302652 DOI: 10.2340/aos.v83.40836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Accepted: 05/18/2024] [Indexed: 06/12/2024]
Abstract
OBJECTIVE It is evident that periodontitis is linked to various adverse pregnancy outcomes. This prospective study explored the potential link of maternal periodontal diseases to neonatal adverse outcomes. MATERIALS AND METHODS A total of 193 generally healthy females in their third trimester (34-36 weeks) of pregnancy were enrolled. All subjects received full-mouth periodontal assessment, and the periodontal inflamed surface area (PISA) was calculated. Demographic data, lifestyles and anthropometric measurements of the neonates (e.g., body length and head circumference) were recorded. Herein, small-for-gestational age (SGA) referred to gender- and age-adjusted birth weight below the 10th percentile in line with the standard reference. Multivariable logistic regression analysis and restricted cubic spline were performed for examining the association of periodontal parameters with SGA. Results: There were 8.3% (16/193) of neonates with SGA. Significantly positive correlation existed between the percentage of tooth sites with increased probing depth and an elevated risk of SGA (OR: 1.052; P < 0.05). Yet, the PISA was positively associated with the risk of SGA (OR: 1.002; P < 0.05) as well. No significant link occurred between maternal periodontal status and other neonatal outcome measures. CONCLUSION Within the limitations of this study, the findings suggest that there could be a link between maternal periodontal diseases and neonatal adverse outcomes like SGA. Further investigation is required to clarify the current findings and potential implications for promoting maternal oral/periodontal health and newborn health.

Dental caries, tobacco usage and associated risk factor of dental caries in patients visiting a government hospital in Western, Nepal. BMC Oral Health 2024; 24:219. [PMID: 38342887 PMCID: PMC10859024 DOI: 10.1186/s12903-024-03997-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Accepted: 02/07/2024] [Indexed: 02/13/2024] Open
Abstract
BACKGROUND This study was conducted to assess the prevalence of dental caries, tobacco usage, and associated risk factors for dental caries in patients who visited a government hospital in Western, Nepal. METHODS This analytical cross-sectional study was conducted from January to April 2022. Patients above 18 years visiting the dental OPD of a government hospital, and who had provided informed consent were enrolled in the study using a convenience sampling technique. As the study also involved an illiterate population, in that case, informed consent was obtained from their respective legal guardian as well. A pretested standardized, close-ended questionnaire was administered by researchers to gather information regarding the associated risk factors and oral hygiene practices. Clinical examination was done for dental caries according to the criteria by the World Health Organization (WHO) using the "DMFT" index (WHO modification 1987). Bivariate and multivariable logistic regression was done and the odds ratio and p-value was calculated. For all tests, statistical significance was set at p < 0.05. RESULTS A total of 219 participants completed the study with a mean age of 31.73 ± 12.46. The prevalence of dental caries and tobacco was found to be 80.36% and 5.02% respectively. Participants without health insurance had 2.35 times higher odds of dental caries (95% CI: 1.03-5.36). Not rinsing the mouth after eating sweets was associated with 3.07 times higher odds of dental caries (95% CI: 1.31-7.18). Those who hadn't visited a dentist in the past 12 months had lower odds (0.42; 95% CI: 0.18-0.94). Eating fresh fruit daily showed statistically higher odds (2.70; 95% CI: 1.04-6.99) of dental caries. Non-tobacco users had higher odds (14.19; 2.55-78.99) of dental caries. CONCLUSION Dental caries is highly prevalent, while tobacco usage is relatively low. Factors associated with dental caries included lack of health insurance coverage, consumption of fruits once daily, recent dental visits within the past year, not rinsing the mouth with water after consuming sweets, and non-tobacco users.

Abstract
OBJECTIVES This study was conducted to assess oral hygiene practices, oral health status and barriers to utilization of oral health care services among pregnant mothers attending two family health care clinics in Sunsari, Nepal. METHODS A cross-sectional study was conducted among 139 women using a purposive sampling technique. The data collection was done using a pretested standard semi-structured questionnaire. Face-to-face interviews of the participants were done by a single investigator in the local language (Nepali). The examination was done using a mouth mirror and CPI probe for periodontal status, loss of attachment and dentition status, and treatment needs. RESULTS The majority of pregnant mothers brushed their teeth once a day or less than once a day (n = 106, 76.3%) and self-reported perceived oral health status was poor/fair (n = 93, 66.9%). The prevalence of dental caries was found to be 69.8%. Bleeding on probing was present in all participants. DMFT, presence of bleeding on probing and increased periodontal pocket was significantly high among women who had self-reported their oral health problems in comparison to those who had not reported any problem. The most common barriers reported by the participants were a lack of knowledge of dental checkups and a lack of perceived need for dental care during pregnancy. CONCLUSIONS There was a high prevalence of dental caries and periodontal disease. Lack of knowledge and perceived need for dental care were the major barriers found in this study. Hence, this directs towards the utmost need for improvement in awareness level as well as oral hygiene practices.

Abstract
Plant products have been employed in medicine for centuries. As the world becomes more health-conscious, there is a growing interest in natural and minimally processed products for oral health care. This has led to an increase in research into the bioactive compounds found in plant products, particularly monoterpenes. Monoterpenes are known to have beneficial biological properties, but the specific mechanisms by which they exert their effects are not yet fully understood. Despite this, some monoterpenes are already being used in oral health care. For example, thymol, which has antibacterial properties, is an ingredient in varnish used for caries prevention. In addition to this, monoterpenes have also demonstrated antifungal, antiviral, and anti-inflammatory properties, making them versatile for various applications. As research continues, there is potential for even more discoveries regarding the benefits of monoterpenes in oral health care. This narrative literature review gives an overview of the biological properties and current and potential applications of selected monoterpenes and their derivatives in oral health care. These compounds demonstrate promising potential for future medical development, and their applications in future research are expected to expand.

Prevalence, Severity of Extension, and Risk Factors of Gingivitis in a 3-Month Pregnant Population: A Multicenter Cross-Sectional Study. J Clin Med 2023; 12:jcm12093349. [PMID: 37176789 PMCID: PMC10179599 DOI: 10.3390/jcm12093349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 05/01/2023] [Accepted: 05/04/2023] [Indexed: 05/15/2023] Open
Abstract
The scope of this study was to assess the prevalence, severity of extension, and risk factors of gingivitis among pregnant women. In this cross-sectional study, 220 nulliparous women at 3 months of pregnancy were recruited in 2022 at the first obstetrical visit in Dakar, Senegal. Demographic characteristics, lifestyle habits, prenatal clinical status, and oral clinical parameters were recorded. Multivariable logistic regression modeling was used to assess relationships between gingivitis and risk factors. Eighty-eight percent of women had gingivitis, 15% were classified as moderate and 73% as severe. A total of 66.7% (95% CI [28.8-92.1]) of the sites had bleeding on interdental brushing. The odds for gingivitis decreased significantly for women consuming more than five portions of fruits and vegetables per day (OR = 0.15; 95% CI [0.03-0.66]) and increased in women who had a professional activity (OR = 6.75; 95% CI [1.27-35.87]) and high education. Concomitantly, the percentage of dental plaque (OR = 131.6; 95% CI [10.80-1619.71] and the severity of clinical attachment loss (OR = 7.70; 95% CI [3.16-18.92]) were important risk factors. Inverse associations were observed with increasing body mass index (OR = 0.76; 95% CI [0.63-0.93]). Our results underline that gingivitis cases and bleeding were particularly high among 3-month pregnant women. Literacy and adequate oral hygiene actions to modify behaviors and to achieve meticulous biofilm disorganization could make a favorable change in the gingival health outcome. Additionally, further research is necessary to precisely determine the role of biofilm-induced gingivitis and systemic-induced gingivitis in improving gingival conditions.

Abstract
BACKGROUND AND OBJECTIVE There is a limited number of studies on the performance assessment of the 2017 AAP/EFP classification and the CDC/AAP case definition among pregnant females. This study evaluated the agreement between these two systems and explored a practical tool for screening maternal periodontal diseases by general dentists. MATERIALS AND METHODS Totally, 204 systemically healthy females at different phases of pregnancy underwent a full-mouth periodontal examination. Demographic characteristics, lifestyles, and systemic conditions were recorded. Referring to the CDC/AAP definition, the diagnostic performance of the AAP/EFP classification was evaluated by the area under the ROC curve (AUC) and statistical tests (e.g., Youden's index and kappa coefficient). Additionally, a modified scoring system of the FDI Periodontal Diseases Chairside Guide (FDI-CG) was formulated with the addition of pregnancy for testing accordingly. RESULTS Overall, there were 22.1% of the participants in early phase of pregnancy (7-13 weeks) and 77.9% in late phase (34-36 weeks). The majority of them were below 35 years and non-smokers without gestational diabetes. Notably, 30.9% of subjects presented with Moderate/Severe periodontitis (CDC/AAP), and 35.8% with Stages II-IV periodontitis (AAP/EFP). Referring to the CDC/AAP definition, the AUC, Youden's index, and κ of the AAP/EFP classification were 0.979, 0.890, and 92.9%, respectively. The modified FDI-CG system improved the AUC (0.815), Youden's index (63.0%), and κ (0.544) with reference to the original one. CONCLUSIONS This study shows that the AAP/EFP classification is in high agreement with the CDC/AAP definition among the pregnant women. The phases of pregnancy-integrated FDI scoring system may serve as a convenient screening tool for maternal periodontal diseases in general dental practice.

Abstract
OBJECTIVES The purpose of this study was to systematically assess the epidemic trend of periodontal disease in pregnancy. DATA Eligibility criteria comprised studies that reported periodontitis and the periodontal indicators of BOP (+) or CAL≥4 mm or PD≥4 mm among pregnant women. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were applied where applicable. Risk of bias was assessed using the Critical Appraisal Checklist for prevalence studies proposed by The Joanna Briggs Institute (JBI). Meta-analyses were conducted to estimate the pooled effect measures. Q-statistic, I2 statistic, subgroup and sensitivity analyses assessed study heterogeneity. SOURCES Electronic search of articles was conducted using PubMed, Web of Science, EMBASE, Scopus, and Ovid from January 2000 to January 2022. RESULTS A total of 20 studies were included in the meta-analysis. The prevalence of periodontitis among pregnancy was 40% (95% Confidence Interval (CI): [0.15, 1.00]). The prevalence rates were 67% (CI [0.56, 0.80]), 42% (CI [0.27, 0.57]) and 24% (CI [0.12, 0.37]) for BOP (+), PD≥4 mm and CAL≥4 mm respectively. Regarding subgroup meta-analyses, the prevalence rates of BOP (+) and PD≥4 mm presented a gradual increase throughout pregnancy, while the highest prevalence rate of CAL≥4 mm was in the 2nd trimester. CONCLUSIONS It was observed a high prevalence of periodontal disease in pregnancy. However, heterogeneity was high among included studies. More high-quality epidemiologic investigations on periodontal disease in pregnancy are still needed. CLINICAL SIGNIFICANCE Periodontal disease in pregnancy is highly prevalent which results in a reduced quality of life, frequent systemic pathologies and adverse pregnancy outcomes. Given the unhealthy consequences, public health impact, and expansive disease burden, it is worthwhile to investigate more aspects of periodontal disease during pregnancy.

Abstract
Introduction Gingivitis is a condition that has been associated with an exaggerated inflammatory response of the gums to oral biofilm, attributed to the secretion of hormones during pregnancy. Objectives To estimate the prevalence of gingivitis and identify associated risk factors among pregnant women in a private medical clinic from Acapulco, Guerrero. Material and methods Cross-sectional study in a convenience sample of 92 pregnant women, during the period from January to March 2020. A self-administered questionnaire collected sociodemographic data, economic income, oral hygiene habits and personal pathological history. The periodontium was evaluated based on the new classification of gingival health and gingivitis induced by oral biofilm on six representative teeth. Multivariate analysis identified factors associated with gingivitis using the odds ratio and its 95% confidence interval as an estimate of the strength of association with CIETmap statistical software. Results The prevalence of gingivitis was 60% (55/92). Two factors remained in the final model of the multivariate analysis. The main associated strength was found in the variable of not using oral hygiene aids (ORa= 6.76; CI 95%= 2.01-22.78). The other variable was not attending dental visits (ORa= 3.74; CI 95%= 1.44-9.73). Conclusion Gingivitis affected about six out of ten pregnant women. Knowing the risk factors, it will be important to reinforce health education strategies and the importance of clinical monitoring during pregnancy.

Abstract
Dental caries and periodontal disease represent a health problem and a social cost for the entire population, and in particular for socio-economically disadvantaged individuals who are less resistant to disease. The aim of this review is to estimate the prevalence and severity of the two dental pathologies, caries and periodontal disease, in the different classes of socio-economically disadvantaged subjects and to understand which of them are most affected. A systematic search of the literature was performed in MEDLINE (via PubMed), EMBASE and Web of Science after establishing a suitable search strategy for each database, using keywords related to socio-economically vulnerable classes and health outcomes. Socio-economically disadvantaged individuals are more susceptible to tooth decay and periodontal disease (with relative tooth loss) than non-vulnerable people. Additionally, when multiple vulnerabilities are combined in the same subject, these oral diseases worsen. There is no type of vulnerability more affected by caries and periodontitis than others, since overall they all have severe disease indices. The data from this systematic literature review might be useful for health policy makers looking to allocate more resources and services to socially disadvantaged individuals, resulting in making them more resilient to oral disease due to their social marginalization.

Abstract
As delays in the age for a mother's first pregnancy continue to trend upward globally, particularly in developed countries, many pregnant patients are increasingly educated on the importance of obtaining dental care throughout their pregnancies. Guidelines set forth by the American Dental Association and the American College of Obstetrics and Gynecologists highlight the importance of dental treatment for optimizing maternal-fetal health across all trimesters, especially for emergent dental issues. The pregnant dental patient undergoes significant physiologic remodeling unique to each trimester, which may complicate treatment. Providing safe anxiety and pain control for dentistry can be further complicated if sedation or general anesthesia is required for the parturient. This is even more true when superimposed with increasingly prevalent underlying comorbidities like hypertension and diabetes. As dental providers, there is a clear need for continuing education on the many challenges associated with caring for pregnant patients due to this being an often overlooked subject in undergraduate and postgraduate dental education. Part 1 of this review will present the maternal and fetal physiologic considerations and the impact on patient management from an anesthetic perspective. Additional discussion focusing on common sedative and anesthetic agents used during dental procedures and their considerations will follow in Part 2.

Adherence to and acceptability of three alcohol-free, antiseptic oral rinses: A community-based pilot randomized controlled trial among pregnant women in rural Nepal. Community Dent Oral Epidemiol 2020; 48:501-512. [PMID: 33070354 PMCID: PMC7689705 DOI: 10.1111/cdoe.12562] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2019] [Revised: 05/28/2020] [Accepted: 06/18/2020] [Indexed: 12/15/2022]
Abstract
OBJECTIVES Antiseptic oral rinses have been evaluated as interventions to reduce the risk of adverse pregnancy outcomes associated with periodontal disease in pregnant women. Oral rinse use is not common in Nepal or other countries in South Asia, where the prevalence of adverse pregnancy outcomes is high. Understanding whether pregnant women in rural communities in this region would incorporate rinse use into their daily teeth cleaning routine is an important prerequisite to future research on this topic in South Asia. METHODS We conducted a community-based pilot randomized controlled trial of three alcohol-free, antiseptic oral rinses among pregnant women <22 weeks pregnant in rural Nepal with the aim of assessing rinse acceptability, adherence, and effect on clinical periodontal measures. At baseline, participants underwent a clinical periodontal examination, and then were classified as healthy or having at least mild gingivitis (≥1 site with probing depth (PD) 3 mm and bleeding on probing (BOP) or ≥4 mm (PD)). Participants were stratified by periodontal status and randomized within each exposure category to chlorhexidine (CHX) (0.12%), cetylpyridinium chloride (CPC) (0.05%), salt and water (NaCl), or control (no rinse). Rinse participants were followed weekly for 12 weeks, and all participants underwent a second periodontal examination and answered a questionnaire. RESULTS Pregnant women in the rural Terai region of Nepal showed high adherence to (mean weekly rinse use: 185 mL (standard deviation: 66 mL)) a recommended 210 mL and acceptability of all three rinses. Participants reported greater frequency of tooth brushing with toothpaste and improvements in other recommended oral hygiene behaviours. CHX significantly reduced rates of gingivitis (defined as a participant with BOP ≥ 10% of sites) and the extent of BOP (gingivitis at the end of follow-up for CHX vs control: RR 0.37, 95% CI: 0.16, 0.84). CPC and NaCl rinse groups had rates of gingivitis and extent of BOP similar to the control group (gingivitis at the end of follow-up for CPC: RR 0.81, 95% CI: 0.47, 1.38; NaCl: RR 0.92, 95% CI: 0.55, 1.56). CONCLUSIONS Adherence to and acceptability of three alcohol-free, antiseptic oral rinses were high among pregnant women in rural Nepal. Among participants with mild gingivitis at baseline, CHX rinse was most effective at reducing signs of disease compared to the control group. Oral rinse should be considered as a supplement to current oral self-care routines for pregnant women in settings where rinse use is uncommon and access to oral health services is limited.

Risk of preterm birth associated with maternal gingival inflammation and oral hygiene behaviours in rural Nepal: a community-based, prospective cohort study. BMJ Open 2020; 10:e036515. [PMID: 32819989 PMCID: PMC7443267 DOI: 10.1136/bmjopen-2019-036515] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 07/04/2020] [Accepted: 07/06/2020] [Indexed: 11/09/2022] Open
Abstract
OBJECTIVES Observational studies have identified associations between periodontitis and adverse pregnancy outcomes, but randomised controlled trials evaluating the efficacy of periodontal therapy have yielded inconsistent results. Few studies have explored relationships between gingival inflammation and these outcomes or been conducted in rural, low-income communities, where confounding risk factors differ from other settings. METHODS We conducted a community-based, prospective cohort study with the aim of estimating associations between the extent of gingival inflammation in pregnant women and incidence of preterm birth in rural Nepal. Our primary exposure was gingival inflammation, defined as bleeding on probing (BOP) ≥10%, stratified by BOP <30% and BOP ≥30%. A secondary exposure, mild periodontitis, was defined as ≥2 interproximal sites with probing depth (PD) ≥4 mm (different teeth) or one site with PD ≥5 mm. Our primary outcome was preterm birth (<37 weeks gestation). We used Poisson regression to model this relationship, adjusting for potential confounders. RESULTS Of 1394 participants, 554 (39.7%) had gingival inflammation, 54 (3.9%) mild periodontitis and 197 (14.1%) delivered preterm. In the adjusted regression model, increasing extent of gingival inflammation was associated with a non-significant increase in risk of preterm birth (BOP ≥30% vs no BOP: adjusted relative risk (aRR) 1.37, 95% CI: 0.81 to 2.32). A secondary analysis, stratifying participants by when in pregnancy their oral health status was assessed, showed an association between gingival inflammation and preterm birth among women examined in their first trimester (BOP ≥30% vs no BOP: aRR 2.57, 95% CI: 1.11 to 5.95), but not later in pregnancy (BOP ≥30% vs no BOP: aRR 1.05, 95% CI: 0.52 to 2.11). CONCLUSIONS Gingival inflammation in women examined early in pregnancy and poor oral hygiene behaviours were risk factors for preterm birth. Future studies should evaluate community-based oral health interventions that specifically target gingival inflammation, delivered early in or before pregnancy, on preterm birth.

Feasibility of training community health workers to conduct periodontal examinations: a validation study in rural Nepal. BMC Health Serv Res 2020; 20:412. [PMID: 32393349 PMCID: PMC7212579 DOI: 10.1186/s12913-020-05276-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Accepted: 04/30/2020] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND In many low- and middle-income countries, insufficient human resources limit access to oral health services. Shifting clinical tasks to less specialized health professionals, such as community health workers, has been used as a strategy to expand the health workforce, especially in remote or underserved locations. The objective of this study was to evaluate the validity of periodontal examinations conducted by auxiliary nurse midwives in a rural home setting in Nepal. METHODS Twenty-one pregnant women < 26 weeks gestation from Sarlahi District, Nepal, underwent full mouth periodontal examinations measuring probing depth (PD) and bleeding on probing (BOP) on 6 sites per tooth by one of five auxiliary nurse midwives, who were trained for this study but had no previous training in dentistry. After a 15-min break, each participant was examined again by an experienced dentist. Measures of validity for PD and BOP were calculated comparing the pooled and individual auxiliary nurse midwives to the dentist. A multivariable GEE model estimated the effect of periodontal characteristics on agreement between the auxiliary nurse midwives and the dentist. RESULTS Participant mean age was 22 years (SD: ±3 years), mean PD was 1.4 mm (SD: 03 mm), and 86% of women had BOP (according to the dentist). Percent agreement, weighted kappa scores, and intraclass correlation coefficients for PD, with an allowance of ±1 mm, exceeded 99%, 0.7, and 0.9, respectively, indicating an acceptable level of agreement. Auxiliary nurse midwives tended to report higher PD scores relative to the dentist, although this over-estimation was small and unlikely to impact population-based estimates of important indicators of oral health status. GEE regression modeling indicated similar agreement for mandible vs. maxilla, left vs. right side, and PD (≤2 mm, > 2 mm), and lower agreement for posterior teeth and lingual and proximal sites. CONCLUSION Auxiliary nurse midwives were able to accurately conduct periodontal examinations in a rural home setting, suggesting the potential to shift tasks away from highly trained dentists and periodontal examiners in low-resource communities.

Abstract
Objective To assess the prevalence of missing and damaged teeth among women in the rural southern plains of Nepal using an interviewer-administered tooth assessment module. Setting 21wards in seven Village Development Committees across the Tarai of Nepal in 2015. Participants Resident, married women of children less than 5 years of age or those married in the 2 years prior to the survey, 14 to 49 years of age participating in a mid-year nutrition and health survey in the Tarai region of Nepal. Outcome measures Prevalence of missing and damaged teeth, history of dental problems, oral hygiene practices, access to dental treatment and risk factors for missing and damaged teeth. Results Of 3007 assessed women, aged 14 to 49 years of age, 22.8% (95% CI: 21.4–24.4) reported ≥ 1 missing or damaged teeth; 81.5% (95% CI 80.1–82.9) reported regularly practicing oral hygiene, typically with standard local dentifrices. Pain or discomfort in the oral cavity in the previous 6 months affected 17.6% of women. Among these, 43.8% had sought treatment from a dental facility, pharmacy or village doctor. Home remedies were commonly applied to relieve pain. Conclusion Broken and missing teeth are common, affecting nearly one-quarter of adult women of reproductive age in rural Southern Nepal, as assessed by an interviewer-administered questionnaire.
