P7 Complaints of halitosis related to the extraoral cavity. A preliminary report of 700 consecutive patients

Patients with complaints of halitosis do seek treatment from physicians and dental practitioners, because of the fear that their halitosis may interfere with their social activities. Although the prevalence of halitosis has been reported to be as high as 50%, most physicians and dental practitioners are poorly informed about the causes and treatments of halitosis. In order to care for patients with complaints of halitosis a multidisciplinary team was established at the Erasmus Medical Centre, Rotterdam, The Netherlands. The team included a dental hygienist, an otorhinolaryngologist, and a dentist, who developed a special halitosis programme. One short press release regarding the establishment of the team, was provided to the national press‐centre. In the out‐patient clinic more than 700 patients were seen by the team. Using a structured questionnaire fed to a PC, patients answered questions regarding complaints about the oral cavity, the upper respiratory tract, the throat, their general health, their cleansing habits of the oral cavity, and prior experiences with general physicians, dental practitioners, and medical specialists. They underwent examinations of the extent of their halitosis, of the perioral and neck region, the oral cavity, the upper respiratory tract, and the upper digestive tract. Finally, the members of the team came to a joint diagnosis and a joint treatment plan for every individual patient. Of the first 700 consecutive patients 57% were women. More than 80% were between 20 and 59 years old. One‐third reported that they were never having breakfast or ate only soft food in the morning. Only 2% were diagnosed as having chronic sinusitis, 11% as having pharyngitis, 3% as having laryngitis, and 3% as having tonsillitis.     

Malignant melanoma of the oral cavity. A case report

The oral cavity is a rare location for the development of primary malignant melanoma. Less than 2% of all malignant melanomas develop in the region. A case report is presented, illustrating the management in the site of the palate, together with a review of the relevant literature.     

Spindle-cell hemangioendothelioma of the oral cavity. A case report

We describe a vascular tumor classified as SCH by histological criteria that was found in the mandibular-buccal fold of a 12-year-old girl. Microscopically, the lesion consisted of thin-walled cavernous spaces containing thrombi and phleboliths, and cellular areas composed of spindle-shaped, epithelioid and vacuolated cells. Immunohistochemically, the endothelial vascular lining was highly reactive with HAM56 antibody, while variable reactivity was observed for factor VIII-associated antigen. All cell types were positive for vimentin and anti-PCNA stained less than 3% of the tumor cells. This is the first report of SCH in the oral cavity.     

Donovanosis of the oral cavity. Case report

Donovanosis ( Granuloma inguinale ) is an infectious disease, the effects of which are usually confined to the genital region. Various extragenital manifestations of the disease have been described. This report describes a case where the condition represented in the oral cavity some time after the apparently successful treatment of the genital lesion. Members of both the medical and dental profession serving the northern parts of Australia and adjacent tropical regions should be aware of the possibility of encountering this disease. Delay in its diagnosis may result in extensive tissue destruction and a potentially fatal outcome. Intensive antibiotic therapy followed by long-term follow-up is usually curative.     

A content analysis of advertisements related to oral health in children's Tamil television channels--a preliminary report

International Journal of Paediatric Dentistry 2012; 22: 232–238 Aims. This study was conducted to examine the nature, content, and duration of advertisements broadcasted during children’s Tamil television channels and to determine the extent to which television advertising changes during school holiday and non‐holiday periods and between prime time and non‐prime time broadcast. Methods. Television broadcasts on two main children’s Tamil television channels were video‐recorded over 16 days between 17.00–19.00 hours (non‐prime time) and 19.00–21.00 hours (prime time). For each commercial, the type of product advertised, as well as the duration (in seconds), was recorded. Advertisements were categorized as ‘food’ and ‘non‐food’. The former category was further subdivided into ‘sugar‐rich foods’ and ‘other foods’. The sugar‐rich foods were further categorized as liquid, solid and sticky, and slowly dissolving sugars. Commercials related to the promotion of oral health products and non‐food products were also recorded. Results. Among the total of 128 h of television programmes recorded, advertising accounted for 10.15% (13.01 hours). The advertisement of sugar‐rich food products, non‐food and oral hygiene products occupied 50.36%, 38.41% and 1.90%, respectively, of the total advertising time. Solid and sticky products made up 100% of advertisements in this category on Chithiram television channel, compared with 62.5% of advertisements on Chutti television channel. Conclusion. It was concluded that the advertising of sugar‐rich foods, particularly solid and sticky food products, was broadcasted more in Chithiram television channel, during school holidays and during prime time.     

Rhino-sinusitis related to endosseous implants extending into the nasal cavity. A case report

Rhino-sinusitis may develop as a result of an altered airflow in the nasal cavity causing irritation of the nasal mucosa. A patient is presented who developed recurrent rhino-sinusitis complaints following placement of endosseous implants in the maxilla. Inspection of the nasal floor revealed that two implants had perforated the floor of the nasal cavity. The part of the implants protruding in the nasal cavity was surgically resected via an endonasal approach whereupon the rhino-sinusitis complaints disappeared.     

DNA grading of oral squamous carcinomas. A preliminary report

The prognostic validity of the DNA-malignancy-grade (DNA-MG), ranging on a continuous scale from 0.00 to 3.00 was tested in a preliminary study on 7 patients with oral squamous cell carcinomas. Monolayer smears were prepared after a cell separation procedure from paraffin-embedded surgical tumor specimens. Feulgen staining was performed automatically in a modified Shandon staining machine. A TV image analysis system with an automatic microscope (TAS plus, Leitz, FRG) was used for DNA measurements. The DNA-MG revealed a strong correlation with the patients prognosis. 3 patients who died after having a tumor relapse (mean survival = 10 months) had DNA grades greater than 1.40, whereas patients who survived without having a tumor relapse (mean survival = 53 months) revealed DNA grades below 1.00. Additionally, the DNA-malignancy-grade was closely correlated with the histopathologic malignancy grades.     

Statherin levels in saliva of patients with precancerous and cancerous lesions of the oral cavity: a preliminary report

OBJECTIVE: The aim of this study was to measure concentration of human salivary statherin in patients with oral cavity pathologies and salivary gland diseases. SUBJECTS AND METHODS: Levels of statherin were analysed with High Performance Liquid Chromatography (HPLC) in following groups of subjects: group A: 24 patients with neoplastic diseases of salivary glands, group B: 13 patients with inflammatory lesions of salivary glands, group C: 13 patients with precancerous and cancerous lesions of the oral cavity excluding salivary gland tumors, group D: 20 healthy volunteers (control group). RESULTS: Our preliminary data indicated a sensible reduction of the statherin level in the saliva of patients with precancerous and cancerous lesions of the oral cavity (group C) compared with the healthy subjects (group D). The statherin levels are not significantly reduced either in the inflammatory (group B) or in the salivary glands tumours (group A), compared with the healthy subjects (group D). CONCLUSION: Statherin could play a protective effect in oral cavity in association with its other functions.     

A cheek splitting approach to the posterior oral cavity: a case report

A cheek splitting incision giving good access to lesions of the posterior region of the mouth is described. The incision is particularly useful when the CO2 laser is being used for the resection of malignant neoplasms. For cosmetic reasons the incision is most suitable in elderly patients.     

Primitive neuroectodermal tumour in the oral cavity. Case report

Primitive neuroectodermal tumour is regarded as a rarely seen lesion as it occurs mainly within the central nervous system. However, this neoplasm does occasionally occur elsewhere in the body. One such case which occurred in the posterior part of the palate in a child is reported. Following a combined therapeutic approach comprising surgery, radiotherapy and chemotherapy, the patient has been well for nine years since treatment.     

A desmoplastic granular cell tumour of the oral cavity: report of a case.

A case of granular cell tumour of the buccal mucosa demonstrating marked desmoplasia is presented. The bulk of the tumour is composed of dense collagenous stroma, which surrounds isolated nests of tumour cells. Since the histomorphologic appearance of this variant is different from that usually seen in this lesion, the diagnosis is supported by immunohistochemical demonstration of S-100 and Vimentin in the tumour cells. The authors believe that this case represents the first report of a desmoplastic granular cell tumour of the oral tissues.
