The primary function of a dental implant is to act as an abutment for a prosthetic device, similar to a natural tooth root and crown. Any success criteria, therefore, must include first and foremost support of a functional prosthesis. In addition, although clinical criteria for prosthetic success are beyond the scope of this article, patient satisfaction with the esthetic appearance of the implant restoration is necessary in clinical practice. The restoring dentist designs and fabricates a prosthesis similar to one supported by a tooth, and as such often evaluates and treats the dental implant similarly to a natural tooth. Yet, fundamental differences in the support system between these entities should be recognized. The purpose of this article is to use a few indices developed for natural teeth as an index that is specific for endosteal root-form implants. This article is also intended to update and upgrade what is purported to be implant success, implant survival, and implant failure. The Health Scale presented in this article was developed and accepted by the International Congress of Oral Implantologists Consensus Conference for Implant Success in Pisa, Italy, October 2007.

Patients undergoing periodontal treatment experience perturbations of systemic inflammation of a greater magnitude after non-surgical than surgical periodontal therapy.

OBJECTIVES: A retrospective review of a large series of oro‐facial cases of tuberculosis to analyse clinical, histo‐pathological, and radiological aspects, as well as those of chemotherapy. MATERIALS AND METHODS: A total of 42 cases of tuberculosis of the oro‐facial region were examined. Thirteen patients had a primary form and 29 a secondary form of the disease. Diagnosis was based on careful clinical examination, Mantoux reaction, histopathological examination, microbiological cultures and immunological investigation with the detection of antibodies against Mycobacteria in the patients' serum (ELISA). RESULTS: Cases examined consisted of 27 males and 15 females. The age range was 3 to 73 years (mean age 31 years). Clinical manifestations comprised oral ulcers in 69.1%, bone involvement in 21.4%, and salivary gland and/or lymph node involvement in 14.3%. A total of 79.4% patients with secondary disease had pulmonary lesions, 15 of whom showed clinical and radiological signs of activity; there was one case of bilateral renal lesions and two of skin lesions. CONCLUSIONS: Oro‐facial tuberculosis is often difficult to diagnose and it should be an important consideration in the differential diagnosis of lesions that appear in the oral cavity. The most important diagnostic tools remain a careful clinical evaluation, biopsy for histologic study, as well as acid‐fast stains, culture, and immunological assays, and skin testing.

The adjunctive use of Xan-CHX gel promoted greater PD reductions and CAL gains compared to SRP alone. These results were concomitant with better microbiologic and biochemical outcomes when Xan-CHX gel use was added to SRP, particularly up to 3 months after treatment.

The application of a 1% chlorhexidine gel seemed to be an effective method to reduce bacterial colonization of the implant cavity over a 6-month period.
