Dental management of the pregnant patient

The pregnant patient presents several considerations for providing dental treatment. Among these are that there are two persons involved in the dental treatment of a pregnant woman, the woman and the baby. Each presents a different set of problems. The mother basically presents no difficult problems for dental treatment. She needs to have routine dental treatment provided. All procedures can be done. Because of the fetus, certain precautions in the use of drugs and radiographs must be taken. If it is determined in taking the history that a person may be pregnant and she is not seeing an obstetrician, the dentist should urge her to see one at her earliest convenience. It is well documented that early and good prenatal care decreases the risk to the mother and to the fetus. Diabetes, hypertension, and anemias are frequently associated with pregnancy and produce a threat to the developing fetus. These diseases, along with any other systemic diseases and infections that pose threats to either the mother or the fetus, are normally detected with good prenatal care.     

Management considerations for the pregnant or nursing emergency patient.

It is important to realize the risk-benefit ratio in all therapeutic modalities in any patient and that these variables vary from patient to patient as do circumstances. The emergency patient who is pregnant or nursing should not be feared or be denied appropriate treatment. It is always best to err on the side of safety and remain conservative. The dental problem can usually be treated with the use of adequate local anaesthesia and supplemental nitrous oxide in the second or third trimester. Nevertheless, situations arise that may warrant consultation with the patient's physician or specialist. This brief overview should refamiliarize the dental practitioner with the medications available to treat the gravid patient. It is important to have an understanding of our common therapeutics as well as the inherent treatment risks and benefits as they relate to the changing maternal-fetal physiology.     

The pregnant patient: considerations for dental management and drug use.

The pregnant woman who presents for dental care requires special consideration. This article reviews physiologic changes associated with pregnancy and current considerations for the dental treatment of pregnant dental patients, as well as for pregnant dental professionals. The limitations and safety of commonly used drugs and anesthetics are discussed. Recommendations for prenatal oral counseling are presented.     

Drug therapy for the pregnant dental patient

Providing needed dental treatment, managing oral infection, and controlling pain are essential functions of dentists for helping patients maintain overall health during pregnancy. Medications commonly required for dental care consist of local anesthetics and associated vasoconstrictors, centrally and peripherally acting analgesics, sedative and anxiolytic agents, and antibiotics. Therapeutic drugs routinely used in dental practice are selected because of their known safety and effectiveness. However, for a pregnant patient requiring dental care, the agents routinely prescribed should be reevaluated for potential risks to the mother and/or fetus. The decision to administer a specific drug requires that the benefits outweigh the potential risks of the drug therapy. This article reviews and updates the recommendations for using dental therapeutic agents, thereby enabling general practitioners to select the safest drugs when treating pregnant dental patients.     

Migraine drug therapy: dental implications

Triptan drugs continue to constitute the major pharmacotherapeutic interventional agents for migraine therapy. Interactions of dental drugs with migraine medications are limited, but their seriousness dictates that dentists be aware of the use of ergot alkaloids, triptans, or other migraine drugs. While many migraine sufferers avoid dental therapy dur ing migraine attacks, the practitioner who is treating a patient who has taken migraine medications must carefully monitor the cardiovascular status of the patient, which may affect the use of vasoconstrictors. Macrolide antibiotics and azole antifungals represent additional drug groups that are prescribed by dentists but which may potentiate the adverse effects of migraine drugs. Migraine patients prefer agents that offer rapid onset of relief and total relief within a couple hours of drug administration; they also prefer therapy that prevents recurrences and does not require "rescue" medications, and, of course, a lack of adverse effects and interactions with other medications. Currently, no single drug or class of drugs offers this ideal combination of actions in all patients.     

Oral health during pregnancy: an analysis of information collected by the pregnancy risk assessment monitoring system

BACKGROUND: Little is known about the use of dental services during pregnancy. Yet research suggests that a pregnant woman's oral health and her pregnancy outcome may be associated. METHODS: Four states collected oral health data a part of the Pregnancy Risk Assessment Monitoring System, or PRAMS, in 1998. PRAMS is an ongoing, population-based survey designed to obtain information from mothers who recently delivered live-born infants about their experiences and behaviors before, during and immediately after pregnancy. RESULTS: Reports of dental care use during pregnancy ranged from 22.7 to 34.7 percent. In three states, 12.2 percent to 25.4 percent of respondents reported having a dental problem and of these, 44.7 percent to 54.9 percent went for care. Among mothers reporting a dental problem, prenatal care, or PNC, insurance through public funding and late PNC entry were significantly associated with their not getting dental care. CONCLUSIONS: Most mothers did not go for dental care during their pregnancy; among those who reported having problems, one-half did not get dental care. PRACTICE IMPLICATIONS: Attention toward the oral health needs of pregnant women is warranted. A coordinated effort from the dental and obstetric communities to establish guidelines could benefit maternal oral health and perinatal outcomes.     

Making patients safe and comfortable for a lifetime of dentistry: frontiers in office-based sedation.

Conscious sedation administered in the office setting is one important method for helping people obtain necessary dental care. Patients who may benefit from sedation include the dentally fearful, young children, the behaviorally or medically challenged, and individuals who are undergoing invasive procedures or have problems with gagging or local anesthesia. In-office sedation is effective in reducing apprehension and can improve patient behavior without adversely affecting the patient's physiological status. Mortality and serious morbidity are exceedingly rare in modern practice. Although behavioral strategies are clearly more cost-effective for the patient receiving routine dental care, in-office sedation is usually the least expensive alternative for patients requiring pharmacologic management. Future advances in conscious sedation may include agents and techniques currently thought to be dangerous for nongeneral anesthesia-trained dentists because of their ability to produce rapid changes in anesthetic depth. However, delivery devices such as infusion pumps for drugs like propofol, when coupled with computers to help regulate the infusion rate and monitor the sedative effect, may provide the necessary control for safe administration of propofol and similar drugs by these individuals. A final approach to drug delivery may involve patient-controlled sedation in which the patient self-infuses small boluses incrementally until the desired effect is achieved.     

Dental Care for Pregnant Women

BackgroundThe authors conducted a study to examine factors associated with general dentists' provision of care for pregnant women and the extent to which they provide comprehensive dental care.MethodsThe authors mailed an 86-item questionnaire to 1,000 practicing general dentists in North Carolina. Survey domains included provider knowledge about pregnancy and dental health, dental treatment practices, barriers to providing care, outcome expectancy, and personal and practice demographics. The primary dependent variables the authors analyzed were whether dentists provided any treatment to pregnant women and, among those who did, the extent to which they provided comprehensive services. The authors performed multivariate regression analyses to determine factors associated with dentists' provision of care to pregnant women (P < .05).ResultsA total of 513 surveys were returned (a response rate of 51.3 percent), of which 495 surveys had complete responses. The authors included the completed surveys in their analyses. The mean age of the respondents was 46 years. The results of multivariate analysis showed that respondents who perceived a lack of demand for services among pregnant women and provided preconception counseling were less likely to provide any treatment for pregnant patients than were those who perceived a demand for services and who did not provide preconception counseling, respectively. Dentists who were male, had a low knowledge score, provided preconception counseling and treated largely white populations of patients were less likely than female dentists, those who had moderate or high knowledge scores, and those who treated a population of minority patients to provide comprehensive care for pregnant women.ConclusionsMost general dentists in private practice provide care for pregnant women, but the authors found notable gaps in dental provider knowledge and comprehensive dental services available for pregnant women.Clinical ImplicationsAlthough many general dentists provide some dental care to pregnant women, more should be done to ensure that this care is comprehensive.

Examining the safety of dental treatment in pregnant women

BACKGROUND: Although clinicians generally consider it safe to provide dental care for pregnant women, supporting clinical trial evidence is lacking. This study compares safety outcomes from a trial in which pregnant women received scaling and root planing and other dental treatments. METHODS: The authors randomly assigned 823 women with periodontitis to receive scaling and root planing, either at 13 to 21 weeks' gestation or up to three months after delivery. They evaluated all subjects for essential dental treatment (EDT) needs, defined as the presence of moderate-to-severe caries or fractured or abscessed teeth; 351 women received complete EDT at 13 to 21 weeks' gestation. The authors used Fisher exact test and a propensity-score adjustment to compare rates of serious adverse events, spontaneous abortions/stillbirths, fetal/congenital anomalies and preterm deliveries (<37 weeks' gestation) between groups, according to the provision of periodontal treatment and EDT. RESULTS: Rates of adverse outcomes did not differ significantly (P> .05) between women who received EDT and those who did not require this treatment, or between groups that received both EDT and periodontal treatment, either EDT or periodontal treatment alone, or no treatment. Use of topical or local anesthetics during root planing also was not associated with an increased risk of experiencing adverse outcomes. CONCLUSIONS: EDT in pregnant women at 13 to 21 weeks' gestation was not associated with an increased risk of experiencing serious medical adverse events or adverse pregnancy outcomes. Data from larger studies and from groups with other treatment needs are needed to confirm the safety of dental care in pregnant women. CLINICAL IMPLICATIONS: This study provides evidence that EDT and use of topical and local anesthetics are safe in pregnant women at 13 to 21 weeks' gestation.     

Risk factors for bleeding after dental extractions in patients over 60 years of age who are taking antiplatelet drugs

The aim of this retrospective, single-centre study was to identify the risk factors for bleeding after dental extractions in patients aged over 60 who were being treated with antiplatelet drugs. A total of 338 patients who fulfilled the inclusion criteria were enrolled, and their personal and clinical details, and complications with bleeding after extraction, were retrieved and recorded. There were 182 men and 156 women (mean (SD) age 72 (8) years). A total of 469 teeth were extracted, with a mean (SD) of 1.4 (0.6) teeth/patient. Seventy-seven patients (23%) developed mild, and 55 (16%) severe, bleeding postoperatively. No patient developed a major cardiovascular or cerebrovascular event. We calculated the significance of the association of different variables with the occurrence of postoperative haemorrhage using a multivariate stepwise logistic regression model. The presence of three or more coexisting conditions, a complicated tooth extraction, and the use of two antiplatelet drugs were independent risk factors, while discontinuation of antiplatelet treatment four or more days before the tooth was extracted was a protective factor. This suggests that clinicians should assess the thrombotic risk associated with the interruption of antiplatelet drugs as well as the risk of bleeding for each patient before dental extraction. Strong and effective measures for haemostasis may be preferred over blind discontinuation of antiplatelet drugs. This study is registered in the Chinese Clinical Trial Registry (No. ChiCTR1800014355).     

Respiratory distress

Dental treatment is usually conducted in the oral cavity and in very close proximity to the upper respiratory airway. The possibility of unintentionally compromising this airway is high in the dental environment. The accumulation of fluid (water or blood) near to the upper respiratory airway or the loosening of teeth fragmentations and fallen dental instruments can occur. Also, some of the drugs prescribed in the dental practice are central nervous system depressants and some are direct respiratory drive depressors. For this reason, awareness of the respiratory status of the dental patient is of paramount importance. This article focuses on several of the more common causes of respiratory distress, including airway obstruction, hyperventilation, asthma, bronchospasm, pulmonary edema, pulmonary embolism and cardiac insufficiency. The common denominator to all these conditions described here is that in most instances the patient is conscious. Therefore, on the one hand, valuable information can be retrieved from the patient making diagnosis easier than when the patient is unconscious. On the other hand, the conscious patient is under extreme apprehension and stress under such situations. Respiratory depression which occurs during conscious sedation or following narcotic analgesic medication will not be dealt with in this article. Advanced pain and anxiety control techniques such as conscious sedation and general anesthesia should be confined only to operators who undergo special extended training.     

The pregnant dental patient

When dealing with a pregnant patient, the dental practitioner should keep in mind the various physiological changes that occur in the pregnant female and the potential effects on the fetus in using various types of local anesthesia. This article reviews the current considerations in the use of local anesthesia in the pregnant dental patient, and the safety of local anesthetics, their dosage, and any adverse effect on mother and fetus. It also discusses various dental procedures and the trimester during which they can be performed. Lastly, this article talks about the complications that can occur with a pregnant dental patient in the dental chair.     

Practices and opinions of Connecticut general dentists regarding dental treatment during pregnancy

This study aimed to evaluate the opinions and practices of general dentists in Connecticut regarding dental care during pregnancy. A survey was mailed to Connecticut general dentists to acquire data regarding age, gender, training, type of practice, years in practice, payment types accepted, procedures provided for pregnant women according to trimester, provider comfort level with treating pregnant patients, reasons for not treating pregnant patients, and provider opinions about dental care during pregnancy. The response rate was 42%, yielding a sample of 116 dentists. The majority of respondents (97%) reported treating pregnant patients; however, only 45% felt "very comfortable" treating these patients. All dentists in the sample agreed that physicians need to include an oral health evaluation and appropriate referral for patients' prenatal care. However, 70% of respondents had never received a dental referral for a pregnant patient. The majority of dentists favored providing dental treatment during the second trimester of pregnancy. Most dentists (77%) would take a radiograph for a patient 10 weeks into the pregnancy seeking treatment for dental pain, but only 2% would take routine radiographs regardless of the pregnancy trimester. There was a lack of consensus about medications dentists reported acceptable to prescribe for pregnant patients, and female dentists were significantly less likely than males to prescribe ibuprofen (P < 0.05). At least half of the respondents reported not being completely comfortable treating pregnant patients. Further, many dentists appear to not follow medication prescribing guidelines for this population. While additional research is needed, these initial results indicate that additional education regarding the treatment of pregnant patients would be a beneficial addition to dental school and continued education course curricula.     

Clinical study of anesthetic management during dental treatment of 25 patients with cardiomyopathy

This retrospective study analyzed the management of 25 patients with hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), or dilated phase of hypertrophic cardiomyopathy (dHCM) treated in the outpatient clinic of the Department of Dental Anesthesiology at Hokkaido University. A total of 87 dental treatment sessions were completed. Intravenous sedation was used significantly more often for patients with HCM than those who had DCM. This seemed to be because dental anesthesiologists expected sedative drugs to suppress hyperdynamic circulatory changes caused by mental stress. Intraoperative complications occurred during 19 treatments. The incidence of circulatory complications increased when participants with DCM also reported dental fear. For participants with HCM who reported dental fear, circulatory complications occurred only when sedation was not used. It is not clear whether complications were related to cardiac function or dental treatment. Therefore, it is important to continually monitor patients with these conditions and to be prepared to handle complications that may arise during dental treatment.     

Pregnancy and lactation

Pregnancy results in physiologic changes in almost all organ systems in the body mediated mainly by female sex hormones. Physiologic changes of pregnancy influence the dental management of women during pregnancy. Understanding these normal changes is essential for providing quality care for pregnant women. This review article briefly discusses the cardiovascular, respiratory, gastrointestinal, urogenital, endocrine, and oral physiologic changes that occur during normal gestation. A summary of current scientific knowledge of ionizing radiation is presented. Information about the compatibility, complications, and excretion of the common drugs during pregnancy is provided. Drugs and their usage during breast-feeding are also discussed. Guidelines for the management of a pregnant patient in the dental office are summarized.     

Conceptions of dental amalgam and oral health aspects during pregnancy in Finnish women

Abstract— All 277 pregnant women (mean age 28.4 yr, SD 4.6) living at the Lohja municipal health center area in Southern Finland participated in a survey during the first 6 months in 1990. The women's own opinions of the effect of pregnancy on their oral health were questioned during their first trimester of gestation. A special emphasis was put on the attitudes of dental restorative materials. The results showed that 57% of the subjects would have accepted the use of any restorative material during pregnancy while 43% were against one or more materials. 77 (65%) were opposing dental amalgam. 129 women (47%) were of the opinion that pregnancy as such is detrimental to their dental health. This opinion was significantly more frequent among women who were pregnant for third or more times than those having their first gestation. 70 (26%) thought dental treatment to have an effect on their gestation. Also 70 subjects (26%) thought that dental treatment may affect normal development of the fetus. The results showed that in spite of the long tradition in maternity counseling in Finland, the conceptions among pregnant women are often erroneous from the dental point of view.

An interdisciplinary approach to the dental care of the mentally disabled.

In institutions for mentally disabled persons, dental care of the patient is often difficult because of uncooperative behavior. Premedication is sometimes necessary. The mentally disabled patient frequently receives other medication for behavioral control, cerebral palsy, seizures, or the like, that may interact with the dental premedication. Because of the problems that may develop, a program between an institution's dental department and a university's clinical pharmacy department was developed that provided an approach to the selection of premedication for the dental patient who is mentally disabled.
