Oral Osteomicrobiology: The Role of Oral Microbiota in Alveolar Bone Homeostasis

Osteomicrobiology is a new research field in which the aim is to explore the role of microbiota in bone homeostasis. The alveolar bone is that part of the maxilla and mandible that supports the teeth. It is now evident that naturally occurring alveolar bone loss is considerably stunted in germ-free mice compared with specific-pathogen-free mice. Recently, the roles of oral microbiota in modulating host defense systems and alveolar bone homeostasis have attracted increasing attention. Moreover, the mechanistic understanding of oral microbiota in mediating alveolar bone remodeling processes is undergoing rapid progress due to the advancement in technology. In this review, to provide insight into the role of oral microbiota in alveolar bone homeostasis, we introduced the term “oral osteomicrobiology.” We discussed regulation of alveolar bone development and bone loss by oral microbiota under physiological and pathological conditions. We also focused on the signaling pathways involved in oral osteomicrobiology and discussed the bridging role of osteoimmunity and influencing factors in this process. Finally, the critical techniques for osteomicrobiological investigations were introduced.

Periodontal diseases and potential risk factors in Egyptian adult population-Results from a national cross-sectional study

Background

Despite the interdependence of general and periodontal health, there is paucity of national representative data on the prevalence of periodontal diseases and their associated risk factors in Egyptian population. This cross-sectional study, thus, aimed to assess the prevalence of periodontitis and tooth loss among Egyptian adults and investigate the association between potential risk factors and periodontal diseases.

Methods

A total of 5,954 adults aged ≥ 20 years were included in this study as a subsample from Egypt’s national oral health survey. Periodontitis was diagnosed with Community Periodontal Index ‘CPI’ scores ≥3 and tooth loss not due to caries was included in the analysis. Socio-demographic data and information on behavioral factors and history of diabetes were gathered in a face-to-face interview. Logistic regression was done to interpret the impact of potential predictors on the incidence of the two selected outcome variables.

Results

The overall prevalence of periodontitis was 26% and regression analysis revealed that higher odds of periodontitis existed among illiterate participants (OR = 1.74; 95% CI: 1.40–2.17), smokers (OR = 1.93; 95% CI: 1.69–2.20) and rural residents (OR = 1.16; 95% CI: 1.03–1.30). On the other hand, old age, frequency of dental attendance and history of diabetes were the main predictive factors for tooth loss.

Conclusions

Among Egyptian adults, periodontal diseases were strongly associated with a multitude of modifiable and non-modifiable risk factors and inequalities in distribution of periodontal treatment needs were determined mainly by age, gender, level of education and residency location.

Effects of Soybean Isoflavone and Astragalus Polysaccharide Mixture on Colostrum Components, Serum Antioxidant, Immune and Hormone Levels of Lactating Sows

The objectives of this study were to investigate the effects of soybean isoflavone (SI) and astragalus polysaccharide (APS) mixture on the colostrum components, serum antioxidant, immune and hormone levels of lactating sows. A total of 72 healthy Yorkshire × Landrace lactating sows, were randomly divided into four treatments with six replicates and three lactating sows for each replicate. The control group was fed the basal diet, while the experimental groups were fed the basal diet with 100, 200 and 300 mg/kg SI and APS mixture in the form of powder, respectively. Compared with the control group, (a) the total lactation yield of the 200 mg/kg group was significantly higher (p < 0.05) at 21 days, (b) there was no significant difference in colostrum composition, (c) TG, CHO and MDA content in each treatment group were significantly decreased (p < 0.05), (d) IgA, GH, IGF-1, TNF-α and SOD contents in the 200 mg/kg group were significantly increased (p < 0.05). The SI and APS mixture could improve the average daily feed intake, lactation yield, serum antioxidant activities, immune function, and hormone levels of lactating sows, and the optimum dosage in this study was 200 mg/kg.

Salivary factors related to caries in pregnancy: A systematic review and meta-analysis

BACKGROUND

The authors of this meta-analysis aimed to assess saliva-related caries risk factors, including calcium and phosphate, hydrogen ion concentration, buffer capacity, Streptococcus mutans and Lactobacillus counts, flow rate, and decayed, missing and filled teeth index in each trimester during pregnancy.

TYPES OF STUDIES REVIEWED

The authors searched electronic databases up to July 1, 2019. Eligible observational studies were included. The authors assessed the quality of the included studies by using the Joanna Briggs Institute scale. To estimate the effects of pregnancy, standardized mean differences with 95% confidence intervals were pooled using the random-effects model. Subgroup analysis and meta-regression were used to explore heterogeneity. Publication bias was assessed using Begg and Egger tests.

RESULTS

Twenty-nine studies were included in the meta-analysis, representing 1,230 pregnant women in the case groups and 715 in the control groups (nonpregnant women). The results showed that salivary calcium concentration decreased in the third trimester, salivary phosphate decreased in the second and third trimesters, saliva hydrogen ion concentration decreased in the first and third trimesters, stimulated saliva flow rate increased in the third trimester, and salivary S mutans count increased in the second and third trimesters. In addition, the results showed that saliva calcium, phosphate, S mutans, and buffer capacity amounts had changed from the first trimester to the third.

CONCLUSIONS AND PRACTICAL IMPLICATIONS

In the third trimester, most salivary factors related to caries change and can increase the risk of developing caries in the future. Interventions and screening for caries prevention in pregnancy should start in the first or second trimesters.

Delay in the Referral of Pregnant Patients with Fascial Spaces Infection: A Cross-Sectional Observational Study from Khartoum Teaching Dental Hospital, Sudan

Purpose

Odontogenic infections have the potential to develop rapidly into deep-space infections and compromise the airway. This problem is aggravated by pregnancy because of the physiological changes. This study aimed to determine the causes of referral delay for pregnant patients presenting with fascial space infections.

Methods

Ten pregnant patients with severe odontogenic infections reported to the outpatient clinic at Khartoum Teaching Dental Hospital included in the study during the study period included in the study. Patients with any systemic disease excluded. Demographic data were taken followed by history and then extraoral and intraoral examinations. A predesigned case report form was completed for each patient including the cause of referral delay, the offending teeth, space involved, and trimester at the time of presentation.

Results

The age range was from 18 to 35 years, and the mean age was 26.5 years SD ± 6.3. The odontogenic infections were most common in the last trimester (60%), followed by the late second trimester (40%).The most common tooth involved was the mandibular wisdom tooth (50%), and the submandibular space was the most frequently involved fascial space (70%). All patients were admitted and treated with incision and drainage under local anesthesia; the offending tooth was extracted and intravenous antibiotic and fluids were administered. Patients were on daily dressing until they were discharged on oral antibiotics. Two patients with Ludwig's angina progressed to necrotizing fasciitis.

Conclusion

Misconceptions among women regarding dental treatment during pregnancy were the most common cause of the delay. The myths and misconceptions should be addressed by dentists and prenatal care providers about oral health during pregnancy, and obstetricians' awareness increased that oral health needs special attention during pregnancy.

Influence of Oral and Gut Microbiota in the Health of Menopausal Women

Sex differences in gut microbiota are acknowledged, and evidence suggests that gut microbiota may have a role in higher incidence and/or severity of autoimmune diseases in females. Additionally, it has been suggested that oral, vaginal, and gut microbiota composition can be regulated by estrogen levels. The association of vaginal microbiota with vulvovaginal atrophy at menopause is well described in the literature. However, the relevance of oral and gut microbiota modulation in the immune system during estrogen deficiency and its effect on inflammatory diseases is not well explored. Estrogen deficiency is a condition that occurs in menopausal women, and it can last approximately 30 years of a woman’s life. The purpose of this mini- review is to highlight the importance of alterations in the oral and gut microbiota during estrogen deficiency and their effect on oral and inflammatory diseases that are associated with menopause. Considering that hormone replacement therapy is not always recommended or sufficient to prevent or treat menopause-related disease, we will also discuss the use of probiotics and prebiotics as an option for the prevention or treatment of these diseases.

Use of local anesthetics for dental treatment during pregnancy; safety for parturient

Pregnancy induces significant anatomical and physiological changes in the mother. Many pregnant women need dental treatment due to poor oral hygiene related to pregnancy. However, most dentists are reluctant to provide, and most pregnant women are reluctant to receive, dental treatment during pregnancy. Theoretically, maternally administered drugs are transferred to the fetus. Depending on the types of drugs and the stage of pregnancy, the effects of drugs on the mother, as well as the fetus, may vary. Local anesthetics are the most widely used in dental treatment. It is, therefore, important to understand the potential effects of local anesthetics during pregnancy. In this review, we will focus on the maternal and fetal effects of local anesthetics widely used in dental treatment with consideration of the use of local anesthetics during pregnancy.

Periodontal status during pregnancy and postpartum

Objectives

Different studies have documented an association between periodontal disease and low birth-weight delivery. Hence, knowledge of periodontal status during pregnancy and postpartum is important in order to reduce the risks of both diseases. This study aimed to analyze periodontal status at successive stages of pregnancy and 3–6 weeks postpartum in women with initial periodontal alterations.

Materials and methods

Ninety-six pregnant women were examined at 8–10 weeks (pregnancy diagnosis, baseline), 21–23 weeks and 34–36 weeks of gestation and at 40 days postpartum to record plaque scores, clinically assessed gingival inflammation and probing depth (mean depth and % sites with depth >3 mm). Bivariate and multivariate analyses were performed. Type 1 (α) error was established at 0.05

Results

Plaque Index increased (p = 0.043) throughout pregnancy (baseline, 42%±0.18); 21–23 weeks, 42.6%±0.14; 34–36 weeks, 45.6%±0.13 and decreased postpartum (44.8%±0–13). Gingival Index increased (p<0.001) throughout pregnancy (baseline, 56.7%±0.20; 21–23 weeks, 66.36%±0.17; 34–36 weeks, 74.5%±0.18) and decreased postpartum (59.3%±0.21). Probing Depth increased (p<0.001) throughout pregnancy (baseline, 2.51±0.05; 21–23 weeks, 2.63±0.053; 34–36 weeks 2.81±0.055) and decreased postpartum (2.54±0.049). Percentage of sites with Probing Depth >3 mm increased (p<0.001) throughout pregnancy (baseline, 17.6%±0.16; 21–23 weeks, 23.9%±0.17; 34–36 weeks, 31.1%±0.17) and decreased postpartum (21.2%±0.17) but remained significantly (p<0.02) higher than at baseline.

Conclusion

Periodontal status deteriorates during gestation but improves postpartum.

Periodontal treatment outcomes during pregnancy and postpartum

OBJECTIVE

This study was conducted to compare periodontal therapy outcomes during pregnancy and after delivery.

MATERIALS AND METHODS

One hundred nine pregnant women up to the 20th gestational week (GW) were randomized into two groups: the test group (comprehensive periodontal therapy during pregnancy) and the control group (comprehensive periodontal therapy after delivery). Periodontal examinations comprised plaque index (PI), gingival index (GI), periodontal probing depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and gingival crevicular fluid (GCF) volume. After baseline examination, women in the test group received periodontal treatment up to the 24th GW. The final examination was performed at the 26th to the 28th GW. Women in the control group were treated 30 days after delivery and reexamined 30 days after treatment.

RESULTS

Periodontal therapy significantly reduced periodontal inflammation in both groups. The mean percentage of sites with BOP was reduced from 49.14 % (±22.49) to 11.10 % (±7.84) and from 45.71 % (±17.86) to 8.07 % (±5.21) in the test and control groups, respectively (p = 0.95). No statistically significant differences were observed between groups concerning PI, GI, PPD, CAL, and GCF. The reduction in mean percentage of sites with BOP stratified for initial PPD ≥4 mm was higher in the control group (p < 0.01), but no differences were seen regarding GCF in these sites.

CONCLUSIONS

Hormonal changes during pregnancy do not interfere in treatment outcomes in women with widespread gingival inflammation and limited periodontal destruction. The role of these hormonal changes in pregnant women with different disease patterns remains uncertain.

CLINICAL RELEVANCE

Periodontal health can be reestablished irrespective of the hormonal challenge that takes place during pregnancy.

Oral health and menopause: a comprehensive review on current knowledge and associated dental management

The menopause is physiological changes in women that give rise to adaptive changes at both systemic and oral level. As we all begin to reach an older age, dental health and hygiene becomes a major concern. The dentist is often the first person to appreciate numerous changes that are experienced throughout the body during menopause. The teeth and gums are extremely susceptible to any hormonal changes that take place just before menopause and readily decrease body's ability to fight off minor infections or maintain a healthy balance of useful and harmful bacteria within the oral environment. This review aimed to develop better understanding for major oro-dental complications observed in women during menopause, and schematic approach towards the different dental management protocols used during these periods. Various internets based popular search engines were used to explore related data from literature, which includes PubMed, PubMed Central, Cochrane, Google, Medknow, Ebsco, Science Direct, and IndMed. Upon compilation of relevant data, it was observed that periodontal health is most severely affected (up to 60%) followed by dry mouth (25%) and burning mouth (glossodynia; 15%) which, in turn, may increase the occurrence of oral mucosal and dental diseases, such as candidiasis. Though, the usage of hormone replacement therapy is effective but it does not necessarily prevent or help women with oral symptoms. Therefore, well controlled long-term randomized studies are needed to establish more authentic clinical guidelines for successful management of such conditions.

Factors influencing caries status and treatment needs among pregnant women attending a maternity hospital in Udaipur city, India

OBJECTIVES

To estimate the prevalence and severity of dental caries along with the treatment needs; to determine the factors that influence dental caries status among pregnant women attending a district maternity hospital in Udaipur, India.

STUDY DESIGN

Study sample comprised of 206 pregnant women attending a district maternity hospital in Udaipur, India. Clinical data were collected on dental caries by DMFT and treatment needs as described in World Health Organization Dentition status and Treatment needs.

RESULTS

The overall caries prevalence was 87%. Mean caries experience differed significantly among women in various trimesters, it was found to be 3.59 and 3.00 in 1st and 2nd trimester subjects respectively while it was greatest (4.13) among those in 3rd trimester. One surface filling was the most predominant treatment need. Age and occupation of husband explained a variance of 6.8% and 4.2% for decayed and filled components respectively while the only predictor for missing teeth and DMFT that explained a variance of 9.6% and 5.7% respectively was trimester of pregnancy.

CONCLUSIONS

Dental caries experience and the need for one surface restoration increased with age. Trimester of pregnancy was a significant predictor for missing teeth and DMFT, while decayed teeth and filled teeth were influenced by age and socio-economic level respectively. Key words:Dental caries, treatment needs, pregnant, age, trimester.

Dental considerations in pregnancy-a critical review on the oral care

Pregnancy is a dynamic physiological state which is evidenced by several transient changes. These can develop as various physical signs and symptoms that can affect the patients health, perceptions and interactions with others in the environment. The patients may not always understand the relevance of the adaptations of their bodies to the health of their foetuses. A gestational woman requires various levels of support throughout this time, such as medical monitoring or intervention, preventive care and physical and emotional assistance. The dental management of pregnant patients requires special attention. Dentists, for example, may delay certain elective procedures so that they coincide with the periods of pregnancy which are devoted to maturation versus organogenesis. At other times, the dental care professionals need to alter their normal pharmacological armamentarium to address the patients' needs versus the foetal demands. Applying the basics of preventive dentistry at the primary level will broaden the scope of the prenatal care. Dentists should encourage all the patients of the childbearing ages to seek oral health counseling and examinations as soon as they learn that they are pregnant. This article has reviewed some of the physiologic changes and the oral pathologies which are associated with pregnancy, and how these alterations can affect the dental care of the patient.

Pregnancy, breast-feeding and drugs used in dentistry

BACKGROUND AND OVERVIEW

Despite advances in the study of birth defects related to drug exposures during pregnancy, medication use during pregnancy still causes anxiety and misunderstanding among both members of the public and health care professionals. This may result in a woman's unknowingly taking a medication that may harm the fetus or cause a birth defect or discontinuing medications necessary for treating chronic conditions. Using medications while breast-feeding also represents a challenge for patients and prescribers. Many mothers are told they must stop breast-feeding or "pump and discard" their breast milk if they are taking certain medications; however, in many cases, this advice-based on what may be limited education on the part of the health care provider about breast-feeding and medication use-may be incorrect. The authors review the current evidence regarding drugs that may be safe for pregnant or breast-feeding patients and medications that such patients should avoid.

CONCLUSIONS

When considering prescribing in pregnancy, the dentist must weigh the risk to the fetus versus the benefit to the mother, and the appropriate conclusion should reflect current evidence. In some cases medication dosing should be avoided or altered; however, there are times when it is unnecessary to stop the use of medications. Breast-feeding also represents a clinical challenge, the risks and benefits of which need to be understood by both the patient and practitioner before any medication is administered.

PRACTICE IMPLICATIONS

Dentists should be familiar with the risks and benefits for pregnant or breast-feeding patients posed by five types of medications: analgesics and anti-inflammatories, antibiotics, local anesthetics, sedatives and emergency medications.

V, Vanitha B. Variations in the oral anaerobic microbial flora in relation to pregnancy

INTRODUCTION

Pregnancy gingivitis is a major oral infection. Periodontium acts as a reservoir of inflammatory mediators and sub gingival biofilms of bacteria.

AIM

To evaluate the anaerobic oral microbial flora in pregnant women before delivery and after delivery by comparing them with control group.

MATERIAL AND METHODS

The study group included fifteen cases of pregnant women before and after delivery and healthy non-pregnant women of same age as control group. Sub gingival plaque samples were collected with the help of dentists. The samples were inoculated immediately into Thioglycollate broth (MV010), transported to the laboratory, inoculated on to selective media for anaerobes (Hi-media laboratories) incubated anaerobically (Gas pack).

RESULTS

Prevotella, Tanerella forsythia, Porphyromonas gingivalis and Fusobacterium nucleatum, Veillonella, Peptostreptococcus were isolated.

DISCUSSION

The anaerobic bacteria in pregnant women were Prevotella, Tanerella forsythia and Porphyromonas gingivalis. Viellonella and Peptostreptococcus were seen in control group and after delivery. Research suggests that periodontal pathogens may travel the blood stream from the oral cavity to the placenta.

CONCLUSION

Pregnancy has significant effect on periodontal tissue. There is a significant alteration of bacterial flora during and after pregnancy. Oral health has to become a part of antenatal care /check up.

Oral healthcare considerations for the pregnant woman

Pregnancy is a period of both joy and anxiety in a woman's life and is characterized by various physiological changes in her body brought about by the circulating female sex hormones. The oral cavity is also the seat of changes and these physiologic changes of pregnancy need to be addressed while managing the pregnant woman in the dental clinic. The main goal is to minimize the occurrence of any complications that might harm the mother-to-be and/or the unborn child. Preventive, emergency, and routine dental procedures are all deemed suitable during various phases of pregnancy, with some treatment modifications and initial planning.

CLINICAL RELEVANCE

The dentist should be in a position to manage pregnant women in clinical practice effectively.

Knowledge and Antibiotics Prescription Pattern among Ugandan Oral Health Care Providers: A Cross-sectional Survey

BACKGROUND AND AIMS

Irrational prescription of antibiotics by clinicians might lead to drug resistance. Clinicians do prescribe antibiotics for either prophylactic or therapeutic reasons. The decision of when and what to prescribe leaves room for misuse and therefore it is imperative to continuously monitor knowledge and pattern of prescription. The aim of the present study was to determine the knowledge of antibiotic use and the prescription pattern among dental health care practitioners in Uganda.

MATERIALS AND METHODS

A structured and pretested questionnaire was sent to 350 dental health care practitioners by post or physical delivery. All the questionnaires were sent with self-addressed and prepaid postage envelopes to enable re-spondents to mail back the filled questionnaires. Chi-squared test was used to test for any significant differences between groups of respondents based on qualitative variables.

RESULTS

The response rate was 40.3% (n=140). Of these 52.9 % were public health dental officers (PHDOs) and 47.1% were dental surgeons. The males constituted 74.3% of the respondents. There were statistically significant differences be-tween dental surgeons and (PHDOs) in knowledge on prophylactic antibiotic use (P = 0.001) and patient influence on pre-scription (P = 0.001). Amoxicillin, in combination with metronidazole, was the most common combination of antibiotics used followed by co-trimoxazole with metronidazole.

CONCLUSION

The knowledge of dental health care practitioners in antibiotic use in this study was generally low. A combi-nation of amoxicillin with metronidazole was the most commonly prescribed antibiotics subsequent to different dental pro-cedures.

Local anesthetic use in the pregnant and postpartum patient

The use of systemically absorbed drugs in the gravid and in the lactating patient is of concern to the dentist. This article reviews concerns for the health and safety of the mother, developing fetus, and neonate involving local anesthetics. The available literature on the use of local anesthetics for dentistry in the pregnant and postpartum patient is also reviewed. In addition, the physiology of the pregnant and postpartum woman is discussed because this is essential to understanding potential interplay with local anesthesia and the stress of a dental appointment.

Prenatal dental care: evaluation of professional knowledge of obstetricians and dentists in the cities of Londrina/PR and Bauru/SP, Brazil, 2004

The purpose of this study was to assess the current knowledge and recommendations of obstetricians and dentists as to the dental care to pregnant patients in the cities of Londrina/PR and Bauru/SP, Brazil. Questionnaires were distributed to professionals of both cities, arguing on the following issues: oral health during pregnancy; contact between prenatal care and dental care providers; prenatal fluoride supplementation; selection of therapeutic agents for local anesthesia, pain control and treatment of infection; and dental procedures that can be performed during each trimester. Data were analyzed by frequency of responses and statistical analyses were carried out using X² (type of workplace/service) and t test (time since graduation), significant if p<0.05. Seventy-nine obstetricians and 37 dentists responded the questionnaires. Most physicians referred the patient to dental care only when a source of dental problem was mentioned, limiting the adoption of a preventive approach. Forty-three percent of dentists and 34% of obstetricians did not know the potential contribution of periodontal infection as a risk factor for preterm low birth-weight babies. There was divergence from scientific literature as to the recommendation of local anesthetics (dentists and obstetricians), prenatal fluoride supplementation (obstetricians) and dental radiographs (dentists). The findings of this survey with dentists and obstetricians showed that dental management during pregnancy still presents some deviations from scientific literature recommendations, indicating the need to update these health care professionals in order to establish guidelines for prenatal dental care.

Oral and maxillofacial surgery for the pregnant patient

This article describes clinical approaches for the perioperative management of the pregnant oral and maxillofacial surgical patient. The following topics are discussed: ethical principles of treatment during pregnancy, physiologic changes and their treatment considerations, fetal and maternal risks of various medications, medical problems occurring during pregnancy, and common minimally invasive approaches that the surgeon can apply to minimize the risk to the mother and unborn child. The strategies discussed provide successful treatment outcomes during this important time in the female surgical patient's life.

Drug utilization and teratogenicity risk categories during pregnancy

A limited number of studies have investigated in detail the use of drugs during pregnancy. Researchers in the present study investigated the details of drug utilization in pregnant women during the month before pregnancy, at the time that they became aware of the pregnancy, and during the first trimester. Face-to-face interviews were conducted with 359 pregnant women who were admitted to the fetal medicine unit at a university hospital for diagnosis and follow-up. A questionnaire was used to document sociodemographic characteristics and details of drug use. Drugs were categorized according to the US Food and Drug Administration fetal risk classification. Mean maternal age was 29.9+/-5.1 y, and mean gestational age was 19.6+/-9.5 wk. Many of the pregnant women studied (46.6%) were university graduates, and most (61.9%) had a relatively high annual income. Mean gestational age when participants first learned of their pregnancy was 39.8+/-16.4 d. One hundred seventeen participants (32.6%) used drugs during the month before conception, 54 (15%) at the time when they learned of their pregnancy, 180 (50.1%) at the time of the interview, and 289 (80.5%) during the first trimester. The percentages of drugs in categories D and X used by these subjects were 14%, 13.5%, 2.9%, and 5.9%, respectively. Most of the drugs were hormones. The total rate of drug utilization was not high before and during the first trimester of pregnancy. A considerable number of women were using drugs from the D and X categories; however, these numbers decreased significantly when women learned of their pregnancies. Intake of folic acid, vitamins, and iron was very low during the preconception period and was not high enough during the first trimester; this suggests that particular attention should be paid to the use of beneficial "safe" drugs during the preconception and early pregnancy periods.

Pregnancy: physiologic changes and considerations for dental patients

Human gestation is a period of dynamic physiologic changes designed to support the development fetus. Systems affected include the respiratory, gastrointestinal, circulatory, and musculoskeletal. These alterations influence the patient's general health and make her prone to develop complications unique to pregnancy. Such complications include pre-eclampsia, gestation diabetes, and pregnancy tumors. The fetus's development is also affected by its mother's health, social habits, and medication usage. To protect both the mother and unborn child, dental professional may need to incorporate maternal counseling, treatment modifications, or changes to their customary medication repertoire.

Oral and vulvar changes in pregnancy

The endocrinologic, immunological, and vascular changes that occur during pregnancy are far-reaching. These systemic factors produce profound local impact on the physiology and pathology of the oral cavity, vagina, and vulva. Physiological changes can be expected and tolerable or of such severity that they are viewed as pathological. Existing disease can be exacerbated and dermatoses specific to pregnancy can erupt. Each of these conditions can pose potentially challenging treatment considerations.

Osteomyelitis of the mandible during pregnancy

A 21-year-old woman who was 9 weeks pregnant presented with osteomyelitis of the mandible that resolved spontaneously after delivery. To our knowledge a link between osteomyelitis of the jaws and pregnancy has not been reported previously.
