Oral Health Related Quality of Life in Young Individuals with Dental Anxiety and Exaggerated Gag Reflex.

PURPOSE: To measure the oral health-related quality of life (OHRQoL) among young individuals presenting with dental anxiety and exaggerated gag reflex and to compare it to the OHRQoL among young individuals attending restorative dental treatment. MATERIALS AND METHODS: Patients with dental anxiety and/or exaggerated gag reflex who were referred to the Department of Oral Medicine were included. Clinical examinations included DMFT index (Decayed, Missing and Filled Teeth) according to the WHO criteria and oral hygiene was assessed with the plaque index (PI). The survey included the validated Hebrew version of the Oral Health Impact Profile (OHIP-14). RESULTS: Overall, 322 patients completed the study. The dental anxiety group consisted of 68 patients, the exaggerated gag reflex group of 54 patients and the control group of 200 patients. Control group patients presented with lower PI and DMFT values. Patients with dental anxiety and/or exaggerated gag exhibited worse OHIP-14 scores overall as well as on each separate subscale. PI and DMFT were found to be in strong relation to the OHIP-14. Multivariable logistic regression analysis of factors influencing the OHIP-14 scores revealed a significant influence of the DMFT score. CONCLUSIONS: Patients with dental anxiety and exaggerated gag reflex were shown to suffer considerably from impaired oral health-related quality of life. This impairment may be attributed to a higher prevalence of caries and avoidance of dental treatment. Those populations should be identified and monitored carefully as well as encouraged to seek the appropriate behavioural treatment in order to improve their dental heath and oral health related quality of life.

Demographic profile, plaque index and DMFT scores of young individuals with dental anxiety and exaggerated gag reflex.

PURPOSE: To characterise demographic and clinical parameters among individuals with dental anxiety and exaggerated gag reflex compared to a control group and to analyse the associations between the various parameters. MATERIALS AND METHODS: Sixty-eight patients with dental anxiety and 54 patients with exaggerated gag reflex were compared to a control group of 200 individuals undergoing dental treatment. The collected data included demographic parameters, health status, smoking habits, Decayed, Missing and Filled Teeth (DMFT) and plaque index (PI) scores. RESULTS: PI was significantly higher among patients with exaggerated gag reflex (1.91 ± 0.95) and dental anxiety patients (1.82 ± 0.89) compared to the control group (1.27 ± 0.74; P < 0.001). DMFT was significantly higher among patients with dental anxiety (13.64 ± 7.57) compared to patients with exaggerated gag reflex (10.52 ± 5.42; P = 0.033), and between both groups compared to the control group (4.09 ± 4.034; P < 0.001). Multivariate logistic regression analysis revealed that PI, DMFT and age were positively associated with exaggerated gag reflex and that DMFT and educational level were positively associated with dental anxiety compared to the control group. DMFT was the only significant parameter positively associated with dental anxiety compared to exaggerated gag reflex. CONCLUSION: DMFT and PI scores were higher among patients with dental anxiety and exaggerated gag reflex. Clinicians should consider additional oral hygiene measures and education, maintenance meetings and recall visits in those patients, as well as using supplementary aids, such as fluoride mouthwash and fluoride varnish applications, to maintain oral hygiene without triggering the exaggerated gag reflex.

Dental treatment for high-risk patients with refractory heart failure: a retrospective observational comparison study.

OBJECTIVE: Heart failure affects large population groups. The understanding of the etiology, pathophysiology, and treatment of heart failure has changed considerably within the last few years. The changes have significant implications for the medical management of the disease, as well as on the ability to provide proper dental treatment for these patients. METHOD AND MATERIALS: A retrospective observational study of the outcome following dental treatment of 54 patients was performed: 32 with refractory heart failure stage D (study group) and 22 patients at risk for heart failure stages A to C (control group). Dental management of these patients concentrated on the prevention of iatrogenic, dental setting- induced, and precipitating factors of heart failure. To prevent deterioration of patients' medical condition, a comprehensive, tailored treatment including adequate anxiolysis, close monitoring, profound dental anesthesia, and close follow-up was used. A previously described three-step gradual level protocol (at home, waiting room, and dental chair) was adopted. RESULTS: All the planned dental procedures were successfully completed. Six patients experienced respiratory distress during treatment, and five patients demonstrated arrhythmias during dental treatment. Only minute differences were found between the groups regarding blood pressure and heart rate. CONCLUSION: Use of the suggested protocol facilitated the completion of planned dental treatments for all patients. Thus, providing essential dental treatment for severe heart failure patients with special attention to their medical problems and the use of medications and supporting means to prevent health-compromising situations is recommended.

A new management approach for dental treatment after a cerebrovascular event: a comparative retrospective study.

OBJECTIVE: Current literature recommends postponing dental treatment until 6-12 months after a stroke, based on the presumed risk of recurrent stroke. The purpose of this study was to suggest that the importance of dental care during this period exceeds the risk of medical complications in this patient population. STUDY DESIGN: Two groups were compared: 1) a cerebrovascular (CrbV) study group: patients (n = 16) who had suffered from a CrbV event within the 12 months preceding their dental procedure; and 2) a cardiovascular (CV) control group: patients (n = 25) suffering from ischemic CV disease. Patients were monitored during and after the dental treatment. Treatment parameters and outcome were compared. RESULTS: Patients received various essential dental treatments with intense monitoring during their dental management. Dental procedures were invasive in 68.8% and 0% of CrbV and CV groups, respectively. Dental treatments were completed uneventfully. No clinical CrbV or CV complications were noted in either group after the dental treatment. CONCLUSION: Within the limits of this small retrospective study, it appears that dental treatment may be safely administered in patients a few weeks after the CrbV event as long as these patients are kept under optimal medical surveillance.

Oral manifestations of habitual khat chewing: a case-control study.

BACKGROUND AND OBJECTIVES: Khat, or qat (Catha edulis), is a shrub indigenous to Yemen and certain parts of eastern Africa. Chewing the leaves, which have sympathomimetic and euphoric effects, is a popular habit in numerous countries including the Yemenite population in Israel. Khat has potentially significant toxic effects; however, its oral effects have been only sporadically examined and some changes suggested. The aim of this study was to assess the association between habitual Khat use and oral/dental pigmentation, gingival health, and reports of oral dryness. STUDY DESIGN: Forty-seven Yemenite Israeli individuals >30 years old, who chewed Khat at least twice a week for over 3 years, and 55 control subjects were studied. All individuals underwent standard clinical oral examinations for color changes and gingival health. RESULTS: White changes were significantly more prevalent in the khat chewers, identified primarily at the chewing site (83% vs. 16%). The difference in the prevalence of oral mucosal pigmentation between nonchewing nonsmoking (66.7%) and the khat-chewing (100%) groups was highly significant. The mean gingival index and the depth of periodontal pockets of the khat-chewing subjects were significantly reduced at the chewing side compared with the nonchewing side. Increased gingival recession was recorded on the khat-chewing side. Discoloration of the teeth adjacent to the site of chewing was recorded. Oral dryness occurring 30 minutes after initiating the khat-chewing session was reported by khat users. CONCLUSION: Khat chewing may result in a number of changes in the oral mucosa and the dentition. The mechanical and chemical irritation may result in the development of mucosal white lesions and dark pigmentation. Khat chewing may reduce aspects related to risk of gingival and periodontal inflammation, but it appears to be associated with attachment loss at the site of chewing.

Does granisetron eliminate the gag reflex? A crossover, double-blind, placebo-controlled pilot study.

Although gagging is a frequent problem that, when severe, can jeopardize the dental procedure, no single protocol is used to alleviate this phenomenon. Selective 5-HT3 antagonists, such as granisetron, may attenuate gagging. In this study, granisetron and placebo were administered intravenously, in a crossover, double-blind manner, to 25 healthy volunteers in 2 different sessions. Gagging levels were recorded before and after administration, as were BP, pulse, and O2 saturation. Recorded results were analyzed with the use of tests for nonparametric values (P = .05). A significant increase in the depth of swab insertion was noted after administration of both placebo and drug. The increase in drug effectiveness correlated with decreased body weight. The true efficacy of granisetron in gagger patients with this treatment protocol has yet to be fully established, although it has been theorized that an increased dosage of granisetron may have a better effect.

Oral lesions in patients participating in an oral examination screening week at an urban dental school.

BACKGROUND: Dental education must emphasize early diagnosis and management of oral mucosal disease, including early detection of oral premalignant lesions and cancer. The authors evaluated clinical findings of oral screening examinations of dental patients during a one-week period in an urban dental school clinic. METHODS: Third- and fourth-year dental students conducted clinical screening examinations for all dental patients of record seen during the Yul Brynner Foundation's Oral, Head and Neck Cancer Awareness Week in April 2006. RESULTS: Of 262 patients, 100 (38.2 percent) reported that they had used tobacco for a mean of 8.1 years. Most patients reported having denture or tooth and gingival problems. The dental students reported abnormal findings in 55 patients (21 percent). Two patients had suspected premalignant lesions that were diagnosed as lichen planus and traumatic keratosis. CONCLUSIONS AND CLINICAL IMPLICATIONS: The one-week screening provided an educational opportunity for the dental students, and the results demonstrate the value of having a focused week to reinforce the importance of head and neck and oral soft-tissue examination. The finding of mucosal lesions in 21 percent of patients of record reflects the fact that lesions were present but undetected. In addition, there are important implications for teaching and patient care. The screening week provided an opportunity for students to be active in a national campaign for cancer detection, and it represents an opportunity for visible community participation in the recognition of oral mucosal diseases in dental training programs and broadly for the profession.

The cardiovascular effect of local anesthesia with articaine plus 1:200,000 adrenalin versus lidocaine plus 1:100,000 adrenalin in medically compromised cardiac patients: a prospective, randomized, double blinded study.

OBJECTIVES: This study compared cardiovascular safety profiles of 2 local anesthetics (LA): articaine (Ubistesine) versus standard lidocaine solution in cardiovascular patients. STUDY DESIGN: Fifty cardiovascular patients were randomly assigned to dental treatment using 1.8 mL of one of two LA injections: articaine 4% and adrenalin 1:200,000 or lidocaine 2% and adrenalin 1:100,000. A computerized system enabled continuous longitudinal data collection: electrocardiography (ECG), O(2)-saturation, blood pressure (BP), and heart rate (HR). Patients scored pain level at the end of the LA injection (on a 0 to 10 scale). RESULTS: There were no clinical severe adverse effects. One transient local parasthesia occurred (lidocaine group), which lasted 4 weeks. There were no statistically significant differences between the 2 groups in HR, systolic or diastolic-BP, and O(2) saturation. Age, gender, jaw treated, treatment duration, and the pain level did not influence the results of the comparison. In 3 patients asymptomatic ischemic changes were noted on ECG (1 in the lidocaine group and 2 in the articaine group). CONCLUSIONS: LA with articaine 4% with adrenalin 1:200,000 was comparably as safe as LA with standard concentrations of lidocaine and adrenalin in cardiovascular patients. Cardiac ischemic changes on ECG did not appear to be related to the LA.

Preemptive analgesia and local anesthesia as a supplement to general anesthesia: a review.

General anesthesia (GA) and local anesthesia (LA) evolved on separate tracks. Procedures that could not be performed under LA were typically conducted under GA. Decoding of afferent linkage of peripheral noxious stimuli has provided important understanding that may change the way we traditionally treat surgical pain. In the 1980s, animal studies suggested that preemptive peripheral blocking of painful (nociceptive) stimuli to the central nervous system with regional anesthesia or LA and nonsteroidal analgesics could be beneficial in attenuating postoperative pain. Clinical studies based on this knowledge suggest combining LA with GA, and perhaps non-steroidal analgesics with or without narcotics, to reduce the severity of postoperative pain. General anesthetics can be given in lower minimal alveolar concentration when combined with LA, and recovery characteristics are superior. Increasing evidence suggests that the combined use of GA and LA may reduce the afferent barrage of surgery, and that preemptive analgesia may reduce postoperative pain and should be used in patient care. This article reviews the evidence supporting the combined use of LA or analgesics with GA or sedation to provide improved pain management after surgery.

A survey of pain, pressure, and discomfort induced by commonly used oral local anesthesia injections.

Intraoral local anesthesia is essential for delivering dental care. However, it is often perceived by some patients as the most painful and in some instances as the only painful part of the treatment, leading in extreme cases to avoidance of dental care. The present study measured the variables of pain, pressure, and discomfort caused by 4 commonly used local anesthesia injections: local infiltration, mental nerve block, inferior alveolar nerve block, and periodontal ligament injections. Patients were asked to grade pain, discomfort, and pressure on a visual analog scale as associated with needle insertion, operator finger position in the mouth, and pressure at injection. The inferior alveolar injection was graded to be the most painful followed by periodontal ligament and then mental nerve block injections. The periodontal ligament injections yielded the highest pressure scores. The inferior alveolar block injection yielded significantly more discomfort than local infiltration and mental nerve block injections when comparing finger and needle position. Local infiltration in the anterior maxillary region yielded the highest needle insertion and finger position discomfort scores. The present study suggests that the dental operator should be aware of local anesthesia injection pain, pressure, and discomfort together with efficacy of technique.

Smoking habits among patients diagnosed with oral lichen planus.

INTRODUCTION: Oral lichen planus (OLP) is one of the most common dermatologic diseases that manifests in the oral cavity. The purpose of this study was to evaluate the association between smoking habits and the clinical subtypes of OLP. METHODS: Oral findings and smoking data from 187 charts of OLP patients from an oral medicine clinic was reviewed and compared to data from 76 matched control patients. RESULTS AND DISCUSSION: Ninety-three patients were diagnosed with reticular OLP, 55 with atrophic and 39 with erosive forms of the disease. Symptomatic OLP occurred in 63.6% of patients. Fewer cases of reticular OLP were symptomatic than erosive OLP (p < 0.001). Significantly fewer OLP patients smoked than the control group (16% versus 25%) (p = 0.04). More patients with reticular OLP smoked than those with atrophic and erosive OLP (p = 0.002). It is hypothesized that the heat and irritation of smoking may aggravate symptomatic OLP lesions, and the risk of malignant transformation associated with tobacco use may play a role in patients stopping tobacco use. Because there were fewer smokers in patients with OLP, and because OLP carries an increased malignant risk, transformation of OLP may be due to a different etiology and of a different pathogenesis than squamous cell carcinoma not arising from lichen planus. Close follow-up of patients with OLP is indicated.

The influence of sequence of impressions on children's anxiety and discomfort.

PURPOSE: Laboratory studies with adults and children have found lower pain reports when pain proceeds from high to low rather than from low to high. However, pediatric dentists often ease children into difficult procedures (from easiest to most difficult). This study investigated the influence of order during a clinical procedure that involved taking maxillary and mandibular alginate impressions. METHODS: Subjects were 24 children aged 5 to 6 years (preoperational stage) and 24 children aged 9 to 10 years (concrete operational stage). Children were randomly assigned to either start with the mandibular (presumed to be easier) or start with the maxillary (presumed to be harder) impressions. Discomfort during the sequence of impressions was measured using the "Affective Facial Scale." A telephone interview was conducted 2 weeks later to evaluate the memory of discomfort. RESULTS: The results indicated that the older children who started with the mandibular (easier) impression and ended with the maxillary (more uncomfortable) impression reported significantly lower discomfort than older children who started with the maxillary impression and ended with the mandibular (Mann-Whitney U, Z = -2.08; P < .037). The same tendency was noted 2 weeks later on a telephone interview. By phone, 92% of the older children who started with the mandibular impression rated the sequence of impressions as "not at all bad," while only 58% of the older children who started with the maxillary impression rated the overall experience as "not at all bad" (chi2 = 3.56, P < .059). The younger children did not show any significant difference in their ratings of discomfort at either of the assessment periods. CONCLUSIONS: Consistent with clinical practice, this study observed that older children benefit from beginning an appointment with an easier procedure and working up to a more difficult one.
