Treatment of patients who have type 1 diabetes mellitus: physiological misconceptions and infusion pump therapy

BACKGROUND

This article reviews the unique physiology of patients who have type 1 diabetes mellitus (insulin-dependent diabetes mellitus, or IDDM); allays some common physiological misconceptions; and updates dental practitioners on the emerging technology of insulin infusion pump therapy, now available to patients who have type 1 diabetes mellitus.

DESCRIPTION

The authors review the physiology of stress and describe the dawn phenomenon. They also describe insulin infusion pump therapy, as well as its advantages and disadvantages, to familiarize dentists with new technologies in caring for patients who have diabetes. Emergencies that may present themselves as a result of these advances in biotechnology are discussed.

CLINICAL IMPLICATIONS

Dental practitioners who treat patients who have IDDM need to have a solid foundation in the basic medical sciences and emerging biomedical technology as they each relate to diabetes. Practitioners must become familiar with infusion pump therapy, not only for cases of medical emergencies, but also to customize treatment for patients who have diabetes. Practitioners also need to remain up to date in the rapidly changing realm of caring for people who have diabetes.

Immediate placement and implant loading for expedited patient care: a patient report

This patient report concerns etiologic factors leading to a failed natural dentition, masticatory function, and poor dental esthetics in a 30-year-old woman. The surgical and restorative treatment provided for the patient was designed to address her dental phobia, location of residence, and debilitated oral condition. While the following case report details an example of the clinical success that can be achieved through advances in dental implant treatment, the most satisfying event was not necessarily the procedure itself, but the profound change that the generosity of the osseointegration community has made on the life of a needy individual. Through the active leadership of the Osseointegration Foundation Charitable Grant Program, the patient, whose complex treatment is described here, was able to take advantage of treatment that otherwise would not have been available to her. This complex treatment was enabled by the Osseointegration Foundation and other caring donors.

Treatment of dental anxiety disorders. Outcome related to DSM-IV diagnoses

In this study we evaluated treatment effects in 70 consecutively admitted patients in a specialized university clinic for treatment of dental fear. Thirty-three (47%) of the patients fulfilled the diagnostic criteria for Specific Phobia alone (Dental Phobia, DP), 24 (33%) had severe dental anxiety without fulfilling the criteria for phobia (ND), and 13 (19%) fulfilled the criteria for multiple DSM-IV diagnoses (MD). Dental anxiety was measured prior to, immediately after and at follow-up (mean = 19 months) using Corah's Dental Anxiety Scale and Dental Fear Survey. Dental attitudes were measured by Getz' Dental Beliefs Survey. Dental attendance and everyday functioning were measured by self-report. DP patients received significantly more treatment-sessions as compared to the ND group. Despite significant overall reductions in scores on all psychometric instruments from pretreatment to follow up, patients in the MD group reported significantly more severe anxiety at pre- and post-treatment and at follow-up as compared to patients in the ND group. There was no interaction between diagnostic group and assessment occasion (pre treatment, post treatment and follow up) on the self-reported anxiety. Patients reported significant improvements in self-esteem, social relations and everyday functioning, regardless of diagnostic group. Sixty-three percentage of the respondents had been to the dentist within 1 year after completed treatment. Patients treated by dentists who had received supervised training in exposure treatment had significantly more often seen the dentist at follow-up.

Case study of an anxious child with extensive caries treated in general dental practice: financial viability under the terms of the UK National Health Service

This case study describes the management of Callum, an anxious 7-year-old boy with extensive caries. Callum's dental care was carried out in a general dental practice in the North of England under the terms of the National Health Service. A preventive programme was carried out in conjunction with the restorative philosophy according to guidelines published by the Dental Practice Board in 1997.

[Effect of the parents' dental fear on the child's oral health]

There are various factors which influence the oral status, among them the dental fear. Dental anxious individuals are likely to have more missing teeth and fewer filled ones. This study examined the association between dental anxiety and oral health status in parents and indirectly in children. The authors found that there is positive correlation between dental fear and missing teeth in the older generation. These tendency can also be seen in younger ones.

Structural relationships of dental anxiety, mood, and general anxiety

The aim of this study was to explore the structural relationships between dental anxiety, mood, and general anxiety among 220 dentally anxious patients who participated in a clinical study. A structural equation modeling analysis (SEM) was applied by using the LISREL program on the hypothesized latent variables dental anxiety, mood, and general anxiety, which were measured by means of several psychometric tests. The final model showed that mood and general anxiety had positive factor loadings on dental anxiety. However, the impact of the general anxiety latent variable was not significant as compared with the mood factor. Another finding was that the residual variance for the latent variable dental anxiety was 0.68, indicating that a major portion of the variance is still unexplained by the tested variables. In conclusion, this study showed a relationship between dental anxiety, general anxiety, and mood among dentally anxious patients.

Dental anxiety in relation to mental health and personality factors. A longitudinal study of middle-aged and elderly women

Little is known about the longitudinal course of dental anxiety in relation to age, mental health and personality factors. In 1968 69 a representative sample of 778 women aged 38 to 54 yr took part in a psychiatric examination. Three hundred and ten were followed up in 1992-93. A phobia questionnaire, including assessment of dental fear, and the Eysenck Personality Inventory were distributed to the participants at both occasions. High dental fear was reported by 16.8% of the women at baseline and was associated with a higher number of other phobias, a higher level of neuroticism, more psychiatric impairment, more social disability due to phobic disorder, and a higher anxiety level. Among women who reported high dental fear in 1968 69 (n=36), 64% remitted and 36% remained fearful. Among women with low dental fear in 1968 69 (n = 274), 5% reported high dental fear in 1992-93. Chronicity was associated with higher neuroticism, lower extraversion, and more psychiatric impairment at base-line. Remission was associated with higher extraversion at baseline. Dental anxiety increased or decreased over time in concert with the number of other fears.

Factors associated with dental anxiety among older people in Britain

OBJECTIVE

This paper reports on a study of dental anxiety among adults aged 60 years living independently in Britain.

DESIGN

A national cross-sectional study carried out with the assistance of the Office for National Statistics' Omnibus Surveys in 1999.

SETTING

Data was collected by face to face interviews with older people in their homes.

MEASUREMENTS

Data on dental anxiety were collected from 973 subjects by means of face to face interviews and was measured by the Dental Anxiety Scale (DAS) (Corah, 1969). In addition, data on dental service use and oral health status (self-reported) was collected.

RESULTS

The mean DAS score was 8.4 (sd 3.5), and 13% (129) of subjects were classified as dentally anxious (DAS > or = 13). DAS scores were associated with numerous socio-demographic factors (P < 0.01), self-reported oral health status (P < 0.01) and dental service (P < 0.01) factors. A series of regression analyses revealed that dental anxiety was a significant predictor of a number of behavioural and oral health outcomes.

CONCLUSION

One in eight older people in Britain are dentally anxious and this is associated with their use of services and oral health status (self-reported).

The impact of dental anxiety on daily living

AIM

To explore the impact of dental anxiety on daily living.

METHOD

Twenty people attending a dental sedation clinic completed the Modified Dental Anxiety Scale, and were interviewed privately using a reflexive, in-depth technique. All interviews were audio-tape recorded and transcribed. The transcripts were analysed to identify the impact of dental anxiety upon the participants' daily lives. Twenty-five per cent of the qualitative data was reviewed by an independent researcher to ensure the reliability of the analysis.

RESULTS

The mean age of participants was 41 years (range 23 to 60). The mean MDAS score was 21.5 (range 14 to 25). Five main impacts of dental anxiety were identified: physiological; cognitive; behavioural; health; and social. Subsumed under these broad categories were: the fright response; a vast array of negative thoughts, feelings and fears; avoidance behaviour and behaviours related to eating, oral hygiene, and self-medication; and other manifestations of anxiety in the dental environment including muscular tension, crying and aggression were all identified. Dental anxiety was also found to disturb sleep and to have a profound affect socially, interfering with work and personal relationships.

CONCLUSION

The impact that dental anxiety can have on people's lives is wide-ranging and dynamic.

Patients with cardiac disease: considerations for the dental practitioner

The provision of dental treatment under both local anaesthesia and sedation has an excellent safety record, although medical problems may occur. The high prevalence of cardiac disease in the population, particularly ischaemic heart disease, makes it the most common medical problem encountered in dental practice. Additionally, the increasing survival of children with congenital heart disease makes them a significant proportion of those attending for dental treatment. While most dental practitioners feel confident in performing cardio-pulmonary resuscitation, treating patients with co-existent cardio-vascular disease often causes concern over potential problems during treatment. This article aims to allay many of these fears by describing the commoner cardiac conditions and how they may affect dental treatment. It outlines prophylactic and remediable measures that may be taken to enable safe delivery of dental care.

Needs for oral care among people with intellectual disability not in contact with Community Dental Services

Previous research has found an unmet need for oral care among people with intellectual disability. The key factors which have been indicated are low expectations, fear of treatment, lack of awareness among carers and problems in accessing dental services. The withdrawal of many general dental practitioners (GDPs) from the National Health Service (NHS) may have exacerbated the latter problem in the UK. The aims of the present study were: (1) to assess the extent of unmet clinical needs in a group of adults with intellectual disability living in the community who were not in contact with the Community Dental Service (CDS); and (2) to explore their perceptions of teeth and contact with dentists to identify how oral care can be improved. Interviews were completed with subjects and/or carers and a dental examination was completed. There were higher levels of untreated caries (decay), and gingival or periodontal (gum) problems among the sample than in either the general population, or in a previous survey of CDS users at day centres and residential facilities. The subjects were largely unaware of dental problems, and used the appearance and absence of pain to judge the condition of their teeth. They depended greatly on their carers for decision-making and support with regard to visiting the dentist and tooth-brushing. Carers requested training in oral care and the use of dental services, and support in dealing with clients who have problems tolerating tooth-brushing. The subjects had experienced a wide variation in the treatment provided by dentists, but had not found it difficult to access a dentist despite recent reductions in the availability of NHS dental care. They expressed a particular need for a good relationship with their dentist and for their dentist to have personal skills in relating to people with an intellectual disability. Dental screening checks and oral care training for carers should be made easily available. Care plans should include tooth-brushing and dietary issues for all clients who have their own natural teeth. There are significant training issues for dentists in developing personal skills in total communication, disability awareness and attitudes which value people with intellectual disability.

What hurts during dental hygiene treatment

PURPOSE

The purpose of this study was to examine clients' pain reports for routine clinical procedures during dental hygiene treatment, and to examine the degree to which physical and psychological variables contribute to pain.

METHODS

A convenience sample consisting of 53 (18 male, 35 female) undergraduate students enrolled at Dalhousie University participated as dental hygiene clients. Before treatment, the demographics, dental anxiety, and pain catastrophizing of students were measured. During procedures, dental status was measured. Following procedures, the amount of pain associated with procedures was recorded. Data was analyzed using an SPSS/PC statistical package.

RESULTS

Most procedures were associated with little or no pain. However, probing and scaling were associated with greater pain. Furthermore, 25 percent of the sample reported their pain was > or = 7/10 on at least one dental hygiene procedure. Dental status measures and treatment difficulty did not correlate with pain. Individuals higher in dental anxiety and pain catastrophizing reported greater pain. Multiple regression showed that all predictor variables combined to account for approximately 1/3 of the variance in pain reports.

CONCLUSION

On average, clinical dental hygiene treatment is associated with low levels of pain, but approximately 25 percent of subjects experienced at least one of the seven procedures as being moderately to severely painful. Findings illustrate the need for effective pain management that may be physiologically or psychologically based. Interventions geared toward reducing anxiety and pain catastrophizing may be useful additions to the curriculum of dental hygiene programs.

Behavioural and emotional problems in children referred to a centre for special dental care

This study was conducted among 203 children (103 boys) referred to a centre for special dental care because of a high level of dental fear. It was undertaken to explore to what extent behavioural and emotional problems co-exist in these children compared with children of a Dutch norm group. The children's parents filled out the parental version of the Child Behaviour Checklist (CBCL), before their first appointment at the centre. The behavioural and emotional problems of the children were assessed by this CBCL, and the mean scores of the children in the study were compared with the mean scores of the norm group. The mean scores on all scales, except on the subscale 'sex problems', of the children with a high level of dental fear proved to be significantly higher than the mean scores of the norm group (P< or =0.001). The results indicated that children referred to a special dental care centre not only suffer from high dental fear but also have problems in several other behavioural and emotional areas. These problems appear to be heterogeneous; they were found in several specific problem areas, both external and internal.

Treatment modalities in a dental fear clinic and the relation with general psychopathology and oral health variables

OBJECTIVE

To assess differences among highly anxious dental patients assigned to different treatment modes (i.e. behavioural management (BM), nitrous oxide sedation (NOS), intravenous sedation (IVS). Patients were compared with regard to psychological and dental variables before treatment (e.g. number of decayed teeth), and dental variables after treatment (e.g. number of fillings made).

DESIGN

Dentists experienced in the treatment of highly anxious patients allocated patients to a treatment mode based upon their clinical judgement.

SETTING

Centre for Special Dental Care, Amsterdam, The Netherlands.

SUBJECTS

211 patients from this dental fear clinic.

MEASURES

General psychopathology, as measured by the Symptom Checklist 90 (SCL-90), and dental anxiety (DAS, S-DAI, 10-point scale) were measured prior to treatment. From the panoramic radiograph the following pre-treatment dental variables were assessed: number of teeth, number of decayed teeth, number of retained roots, and number of root-filled teeth. After treatment, number of fillings, extractions, endodontically treated elements, number of visits, and treatment duration, were determined from the patients' records.

RESULTS

Of the 144 patients who received dental treatment at the clinic, 46.5% was treated using a BM approach, 27.8% with NOS, 22.9% with IVS, and 2.8% under GA. No differences among the treatment groups were found with regard to SCL-90 and dental anxiety. The results showed that patients in the IVS group had statistically significant more decayed teeth than patients in the BM group. Furthermore, more fillings were made in the IVS group than in the BM group.

CONCLUSION

Since it appeared possible to treat a large proportion of patients by BM alone, training dentists in the application of psychological methods for the treatment of anxious patients should be stimulated. In addition, future research should seek for variables that, besides oral health, are better able to discriminate between groups of highly anxious patients than measures of dental anxiety and psychopathology.

Dental caries and changes in dental anxiety in late adolescence

Little is known about changes in dental anxiety with ageing and their association with changes in oral health. This study examined the relationship between changes in dental caries experience and dental anxiety from 15 to 18 years of age among adolescent participants in the Dunedin Multidisciplinary Health and Development Study. Dental anxiety was estimated using the Corah Dental Anxiety Scale (DAS), and individuals with a DAS score of 13+ were identified as being dentally anxious. Dental examinations were performed on 649 individuals at ages 15 and 18, and a DMFS score was computed for each. Caries prevalence among those who were dentally anxious at both 15 and 18 years was significantly higher than for those who were not at either age. Regression analysis revealed that dental anxiety predicted caries incidence between ages 15 and 18 years. Dental anxiety is likely to be a significant predictor of dental caries experience, and may be a risk factor for dental caries incidence.

Blood-injury-injection phobia and dental phobia

The present study was carried out to explore the relation between BII phobia and dental phobia. An additional aim was to determine the fainting tendency of dental phobics and BII phobics during an invasive treatment procedure. Participants were 63 patients undergoing treatment in a dental fear clinic, and 173 patients undergoing dental surgery in a university hospital. They completed measures on fears of particular medical and dental stimuli, fainting history, general trait anxiety, dental anxiety, BII anxiety, BII avoidance, and a questionnaire aimed to define a phobia based on DSM-IV criteria. Immediately after treatment information was obtained on exposures to blood or injections, state anxiety, and feelings of faintness during treatment. The results did not indicate any significant relationship between measures of dental anxiety and BII anxiety or BII avoidance. However, 57% of the dental phobic patients could also be classified as BII phobic. The proportion of dental phobics who reported fainting episodes in their past was similar to that of the BII phobics (37%), but none of the participants fainted during treatment. It is concluded that, albeit the level of co-occurrence for both types of phobias is high, dental phobia should be considered as a specific phobia, independent for the BII subtype within DSM-IV. Further, the findings are inconsistent with the notion that individuals with BII phobia have a remarkably high tendency to faint in the presence of their phobic stimuli.

The Australian public's perception of mercury risk from dental restorations

The debate about mercury and dental amalgam has been one of the longest running in dentistry, and shows no signs of abating. This study aimed to investigate perceptions about mercury in dental fillings among a representative sample of the Australian public. A random sub-sample of participants in a national dental telephone interview survey completed a follow-up postal questionnaire which included four items on dental mercury. The postal survey response rate was 85.2%. Concern about mercury in dental fillings was expressed by 37.5%, while 16.2% reported having requested fillings that do not contain mercury. Avoidance of dental care because of concern about mercury in fillings was reported by 5.8%, but only 4.7% reported having had fillings replaced because they contained mercury. The data indicate that there is a substantial degree of concern about mercury and dental amalgam among the Australian public, but that the dental behavioural and treatment-pattern consequences of that concern are infrequent.

Problems complicating dental treatment with local anaesthesia or sedation: prevention and management

The provision of dental treatment under both local anaesthesia and sedation has an excellent safety record. However, problems that either complicate treatment or lead to medical emergencies can arise. This paper considers the prevention of foreseeable problems and the treatment of unforeseeable emergencies in the dental surgery.

The appropriateness of referral of medically compromised dental patients to hospital

Hospital departments of oral and maxillofacial surgery make a substantial contribution to both managing and treating medically-compromised dental patients. Contracting arrangements should take account of this. Demographic data suggest that the treatment of medically-compromised elderly dentate patients will become increasingly important in the General Dental Service (GDS). To determine the medical conditions and treatment requirements prompting referral of these patients to hospital, a prospective study was undertaken of 75 consecutive adults referred for hospital treatment specifically because of a medical condition which prevented delivery of routine dental care in the GDS. Patients (mean age: 56 years) were referred mainly from general medical (33%) and dental (62%) practitioners. Cardiovascular disease was the most frequently cited medical condition requiring referral (43%; n = 32 cases). Forty-eight patients (64%) were symptomatic on presentation and on average had attended on 2.3 occasions before definitive treatment was instituted. Fifty-two patients (70%) had no special treatment requirements other than those available in the GDS, 11 patients (15%) simply required antibiotic prophylaxis and 81% were treated by undergraduates or junior staff. These data suggest that many patients referred for dental hospital treatment because of underlying medical condition are not in fact medically-compromised and may be treated in the primary care setting.

Fatal intracerebral hemorrhage during dental treatment

Although chronic arterial hypertension is the leading cause of intracranial hemorrhage, an abrupt rise in systemic arterial pressure in normotensive people may sometimes induce a hemorrhagic stroke. Dental treatment is rarely associated with such an event. We report here on two middle-aged women, apparently healthy, who suffered from a fatal intracerebral hemorrhage following a dental treatment. On admission, high levels of arterial hypertension were found. It seems that trigeminal manipulation during dental treatment as well as increased serum levels of induced epinephrine mainly by stress and pain, and the small amounts absorbed from the site of local anesthesia might produce abrupt elevation of blood pressure, subsequent increase in cerebral blood flow and severe, even fatal intracerebral hemorrhage. The addition of catecholamines to local anesthetics should be considered. We recommend the use of benzodiazepin as a premedication drug to reduce stress during dental treatment.
