Effects of nonsurgical periodontal therapy on hard and soft tissues

Is Photodynamic Therapy an Effective Treatment for Periodontal and Peri-Implant Infections?

“…[3][4][5][6] Despite the fact that non-surgical periodontal treatment may result in significant clinical improvements in the great majority of cases, evidence indicates that none of the currently available instrumentation techniques are effective in completely eliminating subgingival bacterial biofilm. 7 These limitations may be attributed to several factors such as the complex anatomy of teeth (i.e. furcation involvements, root invaginations), presence of intrabony defects, etc., mechanical limitations related to the size of instruments or invasion of periodontal pathogens into the surrounding soft tissues or possible recolonization of periodontal pockets from other diseased sites or intraoral niches.…”

“…9 Thus, the current evidence indicates that nonsurgical periodontal treatment may result in substantial clinical improvements in the great majority of cases, but none of the currently available instrumentation techniques are able to completely eliminate subgingival bacteria and calculus. 7 Photodynamic therapy (PDT), also called photoradiation therapy, phototherapy, photochemotherapy, photo-acrivated disinfection (PAD), or light-activated disinfection (LAD), was introduced in medical therapy in 1904 as the light-induced inactivation of cells, microorganisms or molecules and involves the combination of visible light, usually through the use of a diode laser and a photosensitizer. 10 The photosensitizer is a substance that is capable to absorb light of a specific wavelength and transform it into useful energy.…”

Mechanical Non Surgical Therapy: An Indispensable Tool

“…Despite various treatment options discussed above, non surgical periodontal therapy still remains the mainstay of the periodontal treatment regimens. 6,7,8,9,10 Despite significant advancements in the knowledge of disease pathogenesis and factors affecting the progression of the disease, traditional approaches to mechanical debridement of the tooth surface to remove tooth accretions continue to be an integral part of periodontal therapy. 11 Also nonsurgical treatment is indispensable for many periodontitis patients, especially for those with systemic diseases, such as heart disease and diabetes, who may not be suitable for periodontal surgery.…”

Efeitos do condicionamento ácido na descontaminação da superfície radicular e no recobrimento radicular: análise em MEV e estudo clínico randomizado

“…A superfície de dentes expostos ao biofilme bacteriano pode apresentar lacunas de reabsorção, as quais contêm em seu interior grande quantidade de bactérias capazes de invadir a estrutura dentária (ADRIAENS; ADRIAENS, 2004). Essa camada pode posteriormente se tornar hipermineralizada pela deposição de íons existentes na saliva e no fluido gengival (WIRTHLLIN et al, 1979).…”

“…No entanto, nenhum procedimento mecânico das superfícies radiculares, seja por meio do emprego de curetas Gracey seja por meio de ultrassom,é 100% eficaz na remoção dos depósitos de placa, cálculo e cemento contaminado da superfície radicular (ADRIAENS; ADRIAENS, 2004;WAERHAUG, 1978;RABBANIET al., 1981;GELLIN et al, 1986), especialmente em áreas de bolsas >5 mm.…”
