Comparison of efficacy of fluconazole mouthrinse and clotrimazole mouthpaint in the treatment of oral candidiasis

Candidiasis is by far the most common oral fungal infection in humans and has a variety of clinical features. It is considered to be an opportunistic infection, affecting individuals who are debilitated by another disease. Fluconazole, one of the newer azoles available for systemic use and clotrimazole as a topical ointment are both shown to be effective in the treatment of oral candidiasis and are considered to be well tolerated and useful medications. No study has evaluated the comparison of clinical and mycological response of oral candidiasis to fluconazole mouthrinse and clotrimazole mouthpaint. The aim of this study was to evaluate the efficacy of fluconazole mouthrinse and compare it with clotrimazole mouthpaint in the treatment of oral candidiasis.     

A systematic review of the management of oral candidiasis associated with HIV/AIDS.

The purpose of this review was to investigate the management of oral candidiasis in HIV/AIDS patients and to evaluate the different guidelines available for its management. A number of topical and systemic antifungal medications are used to treat oral candidiasis in HIV-positive patients. Milder episodes of oral candidiasis respond to topical therapy with nystatin, clotrimazole troches or oral ketoconazole. Fluconazole has been extensively evaluated as a treatment for candidiasis. With HIV-infection, a cure rate of 82% has been achieved with a daily oral dose of 50 mg. Fluconazole was found to be a better choice of treatment for relapsing oropharyngeal candidiasis, resulting in either better cure rates or better prevention of relapse. Intravenous amphotericin B has been found to be effective in azole-refractory candidiasis and is well tolerated. Topical therapies are effective for uncomplicated oropharyngeal candidiasis; however, patients relapsed more quickly than those treated with oral systemic antifungal therapy. Nystatin appeared less effective than clotrimazole and the azoles in the treatment of oropharyngeal candidiasis. Clotrimazole was found to be just as effective for resolution of clinical symptoms as the azoles, except when patient compliance was poor. Fluconazole-treated patients were more likely to remain disease-free during the fluconazole follow-up period than those treated with other antifungal agents.     

Antifungal therapy in oropharyngeal mycotic infections

Oral and pharyngeal candidiasis is a significant infection, particularly in immunosuppressed persons. Candidiasis may be evident as red or white lesions and may produce symptoms. In immunosuppressed persons, oral candidiasis may lead to extensive regional involvement and to systemic infection and can result in death. Because of the significance and prevalence of candidiasis, the recognition and management of infection are important.     

The management of periodontal disease in patients who have received radiation therapy for head and neck cancer

Osteoradionecrosis is a common, serious sequela of radiation therapy for oral cancer. Patients who are to receive radiation therapy should have preradiation dental evaluation and treatment, oral hygiene instruction, and close dental follow-up during and after radiation therapy. Teeth with significant periodontal disease should be extracted before radiotherapy. After radiation treatment, advancing periodontal disease can be initially managed with conservative treatment, scaling and root planing, tetracycline, and good oral hygiene. Periodontal disease is a possible source of infection and may therefore predispose a patient to osteo-radionecrosis.     

Mechanical aids in the prevention of dental diseases in the elderly.

Dental practitioners, who are often unaccustomed to treating geriatric patients, should be taught to accept that old people do not necessarily respond to optimal dental treatment as younger patients do. There is an evident need for continuing education in this respect. The many plaque removing mechanical aids available, such as toothbrushes, toothpicks, and dental flosses, have not been studied in the elderly. Since manual dexterity decreases with increasing age, the use of electric tooth cleaning devices and other aids for improving oral hygiene should be encouraged among the elderly. This is particularly so in patients with physical or mental handicaps. Future studies should investigate the benefits of preventive dental procedures in the elderly and to survey their knowledge, attitudes and behaviour related to oral health. Maintaining proper oral hygiene among the institutionalised elderly has been neglected in many cases. Nurses and other staff in institutions need more information about the role of optimal oral health in the patient's general health and well-being. Staff also need to know more specifically how to help the patients in their daily oral hygiene and how to take care of the patient's dentures. The recently discovered association of poor oral health with life-threatening vascular diseases and other medical catastrophes further emphasizes the importance of maintaining good oral hygiene. Diseases of the mouth and the teeth must be diagnosed and treated in the elderly, who are just as entitled to receive individually designed preventive dental care as are the younger generations.     

Dental implications of mood disorders

Mood disorders refers to a heterogenous group of mental conditions characterized by extreme exaggeration and disturbance of mood and affect. This article examines major depression and bipolar disorders and how these disorders can affect a patient's dental care. The drugs used to treat these conditions have significant side effects that dentists should be aware of. In addition, important drug interactions can occur as a result of agents used by the dentist. The dentist should refer patients found with signs and symptoms of mood disorders for medical evaluation and treatment. Depressed patients often have poor oral hygiene due to a lack of interest in self-care. Xerostomia occurs due to depression and the drugs used to treat it. The dentist needs to provide an aggressive preventive dental education program for these patients, including the use of artificial salivary products, mouthwashes, and topical fluoride applications, in addition to the treatment of candidiasis when present.     

Patient selection for endosseous dental implants: oral and systemic considerations

This paper reviews the literature and discusses patient selection for endosseous dental implants and the effect of systemic and local pathology on the success rate of dental implants. Endosseous dental implants may be preferable to conventional dentures in patients with compromised supporting bone or mucosa, xerostomia, allergy to denture materials, severe gag reflex, susceptibility to candidiasis, diseases affecting orofacial motor function or in patients who demand optimal bite force, esthetics, and phonetics. Conventional dentures or fixed partial prostheses may be preferable to endosseous dental implants in growing and epileptic patients and patients at risk of oral carcinoma, anaphylaxis, severe hemorrhage, steroid crisis, endocarditis, osteoradionecrosis, myocardial infarction, or peri-implantitis. A systematic approach to dental implant patient selection is outlined and centralized reporting of dental implant outcomes is recommended.     

Oral diseases in a patient affected with Prader-Willi syndrome.

BACKGROUND: A case of Prader-Willi syndrome (PWS) in a 13-year-old girl is reported. The patient presents with systemic and oral manifestations of the disease. Case report The patient shows: obesity, hypotonia, mental retardation, small hands, prominent forehead, strabismus, hypoplastic teeth, poor oral hygiene, caries, oral candidiasis and thick, sticky saliva. This case is reported to underline the importance of the oral and dental problems of these patients. Caries and oral candidiasis are correlated with the reduced secretion of saliva and with poor oral hygiene. The role of paediatric dentistry is considered to be necessary for the prevention of oral complications of this syndrome.     

Dental profile of a community of recovering drug addicts: Biomedical aspects. Retrospective cohort study

Objectives: to obtain a biomedical oral profile of a community of adult drug addicts in treatment by analysing their dental health, with a view to determining whether the state of their oral health could be attributed primarily to their lifestyle and the direct consequences of drug abuse on their overall condition, rather than to the effects of the drugs used. Experimental Design: the study was conducted under the terms of an agreement between the Complutense University of Madrid’s (UCM) Odontology Faculty and the City of Madrid’s Substance Abuse Institute. Seventy drug addicts and 34 control group subjects were examined. The study assessed oral hygiene habits, systemic pathology, type of drugs used and the duration of use, oral pathology, oral health indices, risk of caries based on saliva tests, oral candidiasis and periodontal microbiology. Results: statistically significant differences (p<0.05) were found between the test and control groups for practically all the variables analysed. In the drug users group, dental hygiene was wanting, systemic and oral pathology prevailed and the decayed/missing/filled teeth or surface (DMFT/S) indices denoted very poor buccodental health. The saliva tests showed a substantial risk of caries and candidiasis rates were high. By contrast, with a single exception, the microbiological studies detected no statistically significant difference between drug users and control groups periodontal flora. Conclusions: drug-dependent patients had poor oral health and a significant increase in oral pathology, essentially caries and periodontal disease. Their risk of caries was high and the presence of candidiasis was representative of their poor general and oral health. Drug users’ poor buccodental condition was more closely related to lifestyle than to drug abuse itself. Key words:Buccal, dental, drug addicts.     

Candida-related denture stomatitis: a pilot study of the efficacy of an amorolfine antifungal varnish

PURPOSE: Candida albicans is a component of the normal oral microflora, but local and systemic factors can transform this commensal C albicans to a pathogen. The most frequent cause of Candida opportunistic infections (candidiasis) is dentures, especially if poorly fitting or poorly cleaned. Management of oral candidiasis depends on an accurate diagnosis, identification and elimination of predisposing factors, and, often, use of antifungal agents. The aim of this study was to examine fingernail varnish, currently used for onychomycosis therapy, to reduce the fungal colonization in prosthetic biofilms. MATERIALS AND METHODS: A varnish containing 5% amorolfine was applied once or twice a week for 6 months in six patients affected by nystatin-resistant denture-related stomatitis. In all six patients, the prostheses had previously been removed at night, and daily antimycotic topical therapy with nystatin had failed to resolve the stomatitis; after 30 days, these patients all showed persistence of candidal stomatitis. RESULTS: After 1 month, five of the six patients were negative for Candida; this situation was unchanged in the following monthly controls. Only in the patient with suspected Sj?gren syndrome was oral Candida found 15 days after the last varnish application. None of the patients had any complaints about the medication. CONCLUSION: This varnish containing 5% amorolfine, applied once or twice a week for 6 months, was able to suppress the nystatin-resistant denture-related stomatitis.

Talon cusp in the temporary dentition of a patient with Kabuki syndrome: Case report with a two‐year follow‐up

The presence of dental abnormalities in the same individual may be related to syndromic cases and occur through associated systemic changes. Kabuki syndrome presents well‐defined systemic changes, but its clinical characteristics related to the oral cavity have not been fully explained. This study aimed to report the dental changes in a child diagnosed with Kabuki syndrome. A male brown patient aged 2 years and 7 months, accompanied by his mother to the dental visit, they main complaint was the presented of an additional tooth behind upper right central incisor. Anamnesis, intra‐ and extraoral examinations, and dental X‐rays were performed, revealing a talon cusp. Considering the dental clinical findings, the patient was referred to a medical geneticist who additionally requested cardiological and genetic examinations, which established the Kabuki syndrome. The caregivers were advised that the talon cusp would not cause any injury to the natural exfoliation of the tooth and that oral hygiene should be performed carefully. Abnormalities in the oral cavity and developmental delay may be associated with a potential undiagnosed syndrome. The medical evaluation becomes decisive for investigation, diagnosis, and final conduct of the case.     

Update on general health risk of periodontal disease

Objectives : To review the potential of periodontal infections to cause nonoral diseases. Therapeutic recommendations are provided to help patients and dental practitioners prevent systemic complications from periodontal infections. Findings : Systemic diseases from oral bacteria are mostly caused by transient bacteraemias, which can occur spontaneously from dental foci of infection, from mastication, brushing, flossing or other daily manipulations, or from dental treatments. Examples of systemic infections that may involve oral microorganisms include infective endocarditis, aspiration pneumonia, HIV‐related disseminated candidiasis and cancrum oris, septicaemia associated with cancer chemotherapy and radiotherapy, necrotising faciitis and various other life‐threatening infections. Inflamed gingiva constitutes a significant reservoir for herpes viruses, which have the potential to cause serious systemic diseases in immunocompromised patients. Periodontal disease may also aggravate chronic insulin insensitivity and thus interfere with glycaemic control in diabetic patients. Controversy surrounds the involvement of periodontal infections in coronary heart disease. Conclusions : Cumulative evidence suggests that periodontal disease can be an important cause of morbidity and mortality of various systemic diseases, especially in individuals exhibiting compromised host defence. Maintaining a healthy dentition and periodontium by means of daily oral hygiene practice and regular professional care is the most effective way of preventing systemic diseases from oral infections.     

Self-care intervention to reduce oral candidiasis recurrences in HIV-seropositive persons: a pilot study

OBJECTIVES: This single-blind randomized controlled pilot study evaluated the efficacy of a behavioral intervention program, PRO-SELF: Candidiasis, to reduce time to recurrence of oral candidiasis over 6 months in susceptible HIV-seropositive persons. The intervention involved instruction by dentists on improving oral hygiene, minimizing sugar intake, and self-diagnosing candidiasis. METHODS: Participants were adults with oral candidiasis responsive to antifungals who presented to the UCSF Stomatology Clinic between 1997 and 2000. At 2-3 weeks of follow-up visits, a dentist "examiner", masked to group assignment, quizzed participants as to the presence of candidiasis, and assessed candidiasis status. A second, unmasked dentist "instructor" then delivered the program to intervention participants. Participants recorded dietary and oral hygiene practices in 24-h recall diaries: intervention participants at each visit and controls at initial and final visits. RESULTS: At randomization, CD4+ cell counts (cells/mm(3)) were 298 +/- 188 among 18 intervention participants and 396 +/- 228 among 17 controls. The candidiasis recurrence rates at 6 months were 78% among intervention compared with 88% among control participants (hazard ratio 0.72; 95% CI 0.35-1.50). Performing oral hygiene after meals/snacks showed the largest relative improvement: intervention-control difference in proportion of meals/snacks affected was 24% (95% CI -1 to 48%). Self-diagnoses of candidiasis were inaccurate, possibly because of mild episodes. CONCLUSIONS: The results weakly indicate that regular instruction from healthcare professionals helps patients delay candidiasis recurrence by improving oral hygiene. Among HIV-seropositive persons, those with poor oral hygiene, and high-sugar diets are most likely to benefit.     

Fluconazole mouthrinses for oral candidiasis in postirradiation,transplant, and other patients

OBJECTIVE: Oral candidiasis is associated with multiple local and systemic factors. Morbidity and deaths, in high-risk patients, may be prevented by recognition and adequate management. Fluconazole is a systemic antifungal medication that demonstrated clinical advantages in rinsing before swallowing. The purpose of the present study was to evaluate the clinical efficacy of fluconazole aqueous mouthrinses to treat oral candidiasis. METHODS: Ten women and 9 men diagnosed with oral candidiasis used fluconazole (2 mg/mL) aqueous solution 3 times per day as a rinse and-spit topical treatment. The outcome was assessed after 1 week of treatment. RESULTS: Complete symptomatic and clinical relief was noted in 94% of the patients, and a mycologic cure was documented in all but 1 patient. No side effects were reported. Oral rinses with fluconazole suspension may be useful to manage patients with dry mouth or those who have difficulties in swallowing caused by oral candidiasis. CONCLUSIONS: Further double-blind studies are needed to establish the optimal treatment regimen and the usefulness of fluconazole mouthrinses in patients with different risk factors for infection.     

Antibiotic prophylaxis in pediatric odontology. An update

Most orofacial infections are of odontogenic origin, and are of a self-limiting nature, characterized by spontaneous drainage. The causal bacteria are generally saprophytes. On the other hand, invasive dental interventions give rise to transient bacteremia. When an oral lesion is contaminated by extrinsic bacteria, the required antibiotic treatment should be provided as soon as possible. In the case of pulpitis, such treatment is usually not indicated if the infection only reaches the pulp tissue or the immediately adjacent tissues. In the event of dental avulsion, local antibiotic application is advised, in addition to the provision of systemic antibiotics. The dental professional must know the severity of the infection and the general condition of the child in order to decide referral to a medical center. Prophylaxis is required in all immunocompromised patients, as well as in individuals with cardiac problems associated with endocarditis, vascular catheters or prostheses. Penicillin V associated to clavulanic acid and administered via the oral route is known to be effective against odontogenic infections. In the case of allergies to penicillin, an alternative drug is clindamycin. Most acute infections are resolved within 3-7 days. In recent years, the tendency is to reduce general antibiotic use for preventive or therapeutic purposes.     

Oral candidiasis in hematopoietic cell transplantation patients: an outcome-based analysis

OBJECTIVES: Despite aggressive antifungal prophylaxis, the increased risk for systemic fungal infection in recipients of hematopoietic cell transplants (HCT) continues to be a significant concern because Candida infection can cause morbidity and mortality in these patients. The objectives of this study were to examine the relationship of oral colonization by Candida species to systemic infection, mortality, and the impact of antifungal treatment on a population of recipients of HCT. STUDY DESIGN: One hundred and fifteen consecutive patients undergoing hematopoietic cell transplantation were evaluated. Oral examinations and cultures for Candida were completed before transplantation and on a weekly basis until discharge. The oral complications were assessed, and the level of mucositis was scored by using the National Cancer Institute grade. Systemic antifungal prophylaxis was provided to all patients. Chlorhexidine oral rinses were also routinely provided. RESULTS: Colonization by Candida species was identified in 31% of patients. Fifty-six percent of patients with colonization had clinical evidence of oral candidiasis. Significantly decreased Candida colonization was seen in patients using chlorhexidine alone compared with those using chlorhexidine and nystatin together (P <.046). Twenty-five patients died in the immediate posttransplantation period, 17 of whom were Candida-positive. The length of hospital stay ranged from 15 to 153 days; increased stay was also associated with Candida colonization (P =.04). Seventy-four percent of all patients developed ulcerative mucositis. More severe mucositis was seen in patients undergoing chemotherapy and radiation therapy. There was no significant difference between Candida colonization and the presence or severity of mucositis. CONCLUSIONS: Despite systemic and topical antifungal prophylaxis, oropharyngeal colonization by Candida species was common in patients who had received HCT. Candidiasis was commonly present in those who did not survive the early transplant period. Of the 25 patients who died early after the transplantation, 92% had ulcerative mucositis in comparison with 70% of those who survived, reflecting the association of oral mucositis with the toxicity of HCT. There was a significant relationship among allogeneic and autologous HCT, length of stay, and colonization of Candida. In patients undergoing systemic antifungal prophylaxis, chlorhexidine rinse was statistically more effective in reducing colonization by Candida than chlorhexidine and nystatin combined (P =.046).     

Modes of application of anti-plaque chemicals

Because interdental and subgingival sites are relatively inaccessible to mouthrinsing, they necessitate alternative methods of application of anti-plaque chemicals. These include routine oral hygiene aids, surfactants to enhance uptake and retention of antimicrobials, gels and periodontal dressings. The principal modes of application that have received attention recently, apart from the systemic route, are syringe and pulsated jet irrigation and slow release compounds. Slow release devices currently receiving attention may be classified as membrane diffusion, solution of drug in polymer and solid drug dispersed in polymer matrix. The most widespread dental instance of a slow release device appears to be the use of varnishes and resins to carry fluoride. Recent attempts at devising improved methods of antimicrobial application include the testing of materials for their biodegradability or for their potential to adhere to mucosal surfaces. It is concluded that the potential exists for antimicrobials applied directly to the site of intended action to contribute significantly to dental health, particularly when employed as components of practical oral hygiene regimes.     

Oral Hygiene Behavior of Croatian Adolescents during Fixed Orthodontic Treatment: A Cross-sectional Study

ObjectiveTo investigate the impact of fixed orthodontic treatment on adolescents'' oral hygiene behavior and to examine their food consuption during fixed orthodontic treatment, as well as their motivation to maintain oral hygiene.Materials and methodsThis research was carried out in a form of a survey questionnaire consisting of 23 questions. The sample comprised 170 adolescent patients aged from 11 to 19 who underwent the fixed orthodontic treatment at the Orthodontic Clinic of the Zagreb University Hospital Centre.ResultsThe orthodontic appliance did not interfere with the patients’ maintenance of oral hygiene, but it made the consumption of certain foods more difficult. Most adolescents brushed their teeth twice a day, using medium-soft brushes (35%). Regarding additional oral hygiene aids, 72.4% of the respondents used interdental brushes, more than 50% of the respondents used antiseptic mouthwashes for mouth rinsing, whereas only 31.2% of the tested population used dental floss (4.1% of which daily). The respondents were highly motivated to maintain oral hygiene by their orthodontists (96.5%), but only a small number of the respondents were informed about the importance of an adequate diet while undergoing a fixed orthodontic treatment.ConclusionOrthodontists should provide their patients with detailed instructions on hygiene maintenance and adequate diet during orthodontic treatment to minimize negative side effects of the fixed orthodontic treatment. Patients should be motivated upon each follow-up examination and encouraged to use as many oral hygiene aids in their daily routines as possible.     

Peri-implant diseases

Peri-implant diseases are inflammatory conditions that affect the soft and hard supporting tissues around implant fixtures. Peri-implant mucositis usually responds to oral hygiene instructions, scaling and prophylaxis, but peri-implantitis, which involves bone resorption, has less predictable treatment outcomes following non-surgical management. Adjunctive treatment for decontaminating sites may include the use of antimicrobials and resistant cases may sometimes be managed with a surgical approach. CLINICAL RELEVANCE: As dental implant-retained prostheses become more popular the prevalence of peri-implant complications will also increase. Dental practitioners and care professionals should appreciate their potential roles in the management of these conditions.
