The author reports an unusual case of Cancrum Oris in a young nomadic Moroccan patient. They attribute the presence of this condition to poor dental oral care and the neglect of the disease in its early stages. Cancrum Oris can result in oral and facial mutilitations and on some occasions, death. It is proposed that preventative measures, including exemplary oral hygiene and adequate nutrition during infancy and childhood could eradicate the disease.

Gingival thickness is a clinical characteristic which should be given more consideration in evaluating muco-gingival problems. It is proposed that thick gingiva prevents gingival recession and is of particular significance when fixed prosthesis is being employed. The technique outlined includes a connective graft from the lamina propria of the palatal mucosa into the gingival connective tissue. A case report documents the technique.

A study was undertaken to compare the efficiency of a manual toothbrush, unwaxed dental floss, a traditional water irrigating device and a new instrument, the Jet-Floss, in regard to dental plaque removal. The ability to remove 48 hours plaque was assessed among the oral hygiene techniques. The Jet-Floss method was found to be superior in the pericoronal areas than other form of instrumentation. The combined oral hygiene exercise utilizing the conventional toothbrush and the Jet-Floss yielded significantly better results than the use of each single device.

Frequency severity of gingival recessions was studied with Stahl and Morris indices. The results showed that the localization of gingival recession was more important on the mandible (37%) than on the maxillary (27.6%) it, also demonstrated the importance of various etiologies and particularly the association of trauma - tooth malposition (81%).

A 14 years old patient showed a vestibula papilloma. The lesion and the treatment are described. This inflammatory etiology is confirmed by the histologic features of the biopsy.

The periodontal literature contains a paucity of articles dealing with the maintenance of periodontal health after active treatment. The difficulty in doing long term clinical studies relates to the lack of compliance among patients. Well controlled maintenance programs are the main consideration in obtaining a good prognosis over the long term.

A detailed and comprehensive clinical examination is an important and fundamental basis for establishing a proper diagnosis for prosthetic treatment. It is important to make an accurate diagnosis, a rational treatment plan and establishing a prognosis. A careful examination of teeth and periodontium must be done and the prosthetic plan must consider the periodontal status of the teeth. The prosthetic treatment plan must take into consideration problems of appliance retention, iatrogenic tooth injuries and other factors. A classification based on 6 different clinical situations suggested and their therapeutic solution proposed.

A clinical study was performed to compare the in vivo effectiveness of three different instruments for calculus removal. The instruments were Odontoson, Cavitron and Siroson. Following scaling of the roots, the teeth were extracted, stained and assessed for remaining calcareous deposits. Comparative statistical analysis revealed no significant differences among the three methologies.

In order to evaluate the prognosis in tooth transplant procedure the literature on this subject was reviewed. The survival of the periodontal ligament is necessary to prevent ankylosis and root resorption. In order to obtain optimal clinical results, the following guidelines are proposed: preparation of the recipient site 2 weeks prior to graft placement, preservation of intact Pdl at time of extraction, rapid reimplantation of tooth in new socket, short term contention (2-3 weeks); endodontic therapy 8-10 weeks after tooth transplantation.

A case in which an infrabony pocket was treated with Kiel bone is presented. The healing of the lesion was assessed by reentry 9 months after the procedure was completed.
