The study evaluated the antibacterial and anti-inflammatory efficacy, domiciliary oral hygiene, of a mouthrinse containing Tea Tree Oil (TTO) comparing it with two mouthrinses containing chlorhexidine 0,12% respectively and essential oils, and a placebo. Materials and methods A pilot study, randomized 4 × 4, controlled, cross-over, double-blind. 16 subjects with gingivitis (7 males and 9 females) aged 21-37 years, were randomly divided into four groups based on mouthwash that had to be used for domiciliary oral hygiene: mouthwash with essential oils, mouthwash with chlorhexidine 0,12 %, mouthwash containig tea tree oil and mouthwash placebo. Clinical evaluation was performed by: Full Mouth Plaque Score (FMPS), Full Mouth Bleeding Score (FMBS), Gingival Index (GI), discolorations, language examination and alteration of taste. The data were recorded before and 2 weeks after treatment. Results Statistical analysis shows that treatments with tea tree oil, essential oils and chlorhexidine are effective. Comparing treatments should be noted that the tea tree oil gives a greater improvement in the GI and FMBS, while it is the least effective in the control of bacterial plaque. Conclusion Although further studies are needed, the anti-inflammatory properties of the mouthwash made from TTO would seem to be a valuable non-toxic adjunct in the management of gingivitis.

SUMMARY A complication following tooth extraction: a case report of chronic suppurative osteomyelitis. Objective. This article presents a case report about the surgery treatment of chronic suppurative osteomyelitis following a tooth extraction. Methods. Cone beam computed tomography revealed a sequestrum bone formation that required the sequestrectomy and the debridement of the involved area. The prescription of oral penicillin and metronidazole were necessary after and before the surgery. Also 20 sessions of hyperbaric oxygen therapy were important for the healing of the marrow space. Results. The histologic test confirmed the diagnosis of "Chronic suppurative osteomyelitis". Clinically the post-operative course showed no complications but a good healing of the bone tissue. Culture reports revealed two microorganisms, strep- tococcus viridans and staphylococcus, that are sensitive to penicillin. Conclusions. Clinical results confirmed the validity of the sequestrectomy and the debridement of the involved area for the treatment of chronic suppurative osteomyelitis. Such approach has always to be preferred because it guarantees the healing of bone tissue.

In recent years the incidence of fungal sinusitis has increased considerably, due both to increased survival of patients at risk and to improved diagnostic equipment. The pathogen responsible in most cases is the Aspergillus in its forms Fumigatus, Flavus and Niger. The diagnosis is often delayed because the symptoms, characterized by headache, cough, and facial algia, are generally similar to that of chronic bacterial rhinosinusitis. It can be divided into invasive and non-invasive forms based on the clinical evolution and extent of the lesion. We report a case of non-invasive fungal rhinosinusitis in a patient with recurrent sinusitis and pain in the left maxillary region, resistant to antibiotic therapy.

The purpose of this study is to report a case of full-arch rehabilitation on six endosseous implants loaded following the standard procedure. An implant-prosthetic treatment was proposed to a 53-year-old woman with a total prosthesis in the upper jaw. Six implants on upper maxillary were placed keeping the upper complete denture during the osseointegration period. The implants were left submerged to allow the patient to wear removable prostheses and the prosthesis was rebase with Hydrocast to not compress the sites of healing during the osseointegration period. The impression of implants was made with silicones for addition (VPS) with different viscosities after 8 weeks. The final restoration was carried out taking into account the aesthetic and functional canons. Correct diagnosis and accurate implant planning are key for success in implant rehabilitation.
