“…However, in contrast to the present study, they did not distinguish between different pocket depth categories when comparing the BOP values. The observed superior BOP reduction in deep S/RP sites is in line with another study (Christgau et al 2006), which also reported a better BOP reduction in deep pockets with S/RP than with a sonic scaler. Kocher et al (2005) compared the efficacy of the Vector ™ system and a conventional ultrasonic scaler in periodontal maintenance therapy.…”

“…In order to facilitate subgingival debridement and to improve clinical and microbiological results, power‐driven instruments, such as sonic and ultrasonic scalers, have been proposed (AAP Position Paper 2000). Numerous studies have reported similarly favourable clinical healing outcomes following sonic, ultrasonic, and manual instrumentation (Badersten et al 1981, 1984, Loos et al 1987, 1989, Laurell & Pettersson 1988, Laurell 1990, Tunkel et al 2002, Hallmon & Rees 2003, Christgau et al 2006). However, the use of ultrasonic scalers in dentistry may bear some problems for the patients and operators (Trenter & Walmsley 2003).…”

“…demonstrated that both these therapeutical approaches determine similar periodontal healing in terms of probing pocket depths, bleeding on probing and periodontal attachment gain (19)(20)(21)(22)(23)(24)(25), several Authors reported that there is need for less time to treat periodontal patients with the mechanical debridment method (4,25,26). Our results agree with these studies since the mean treatment time for instrumentation of two quadrants was 84.75 minutes for the mechanical versus 119.25 minutes for the manual side.…”

Few studies have focused on the problem of pain and discomfort experienced during and after periodontal debridment. The aim of this study was to evaluate the effect of manual versus hand driven non surgical periodontal instrumentation on the patient's comfort, perception of pain and dental hypersensitivity during and after the instrumentation. Moreover, the influence of the treatment modality on the healing of slight to moderate periodontitis was assessed with careful attention to indices of periodontal inflammation. 22 subjects with a minimum of 42: 6mm periodontal pockets with 3 to 4mm attachment loss in different quadrants, the presence of 2:20 teeth with a minimum offour molars were enrolled. PD (probing depth, 6 sites per tooth), number of sites with PD> 6mm, buccal and lingual recessions were collected. Two quadrants Mouth Bleeding and Plaque Scores (T.M.P.S, T.M.B.S.) were assessed as the presence or absence of bleeding on probing and plaque following disclosing in quadrants 1-4 and 2-3. Non surgical periodontal treatment was delivered in two appointments performed within one week. In the first appointment the first and the fourth quadrants (patient's right side) were completely treated by mechanical or manual devices according to the randomization codes. In the second appointment the remaining two quadrants (patient's left side) were instrumented with the other therapeutical approach. The duration of each session, need for local anesthesia and additional information were recorded during the instrumentation appointments. All the patients were requested to fill in a form regarding pain, hypersensitivity, and need for painkillers following the two debridment appointments. Two drop outs were observed. Mean pain scores after treatment were higher in manual than in machine driven side (3.11±1.40 vs 2.33±1.41), whereas mean dentine hypersensitivity scores were slightly higher in mechanical side (4.40±1.56 vs 3.77±1.11). The need for painkillers after both treatment approaches was minimal. 6 out of 20 patients asked for local anesthesia and clustering regarding the request for both treated sides was observed. The mean instrumentation time was significantly lower for mechanical versus manual instrumentation (84.57±12.92 vs 119.25±13.50, p

“…Responses to periodontal treatment of patients infected with A. actinomycetemcomitans have been investigated (6,10,39). Some previously published studies have even demonstrated that A. actinomycetemcomitans is a pathogen which is able to invade periodontal tissues but evade mechanical-chemical therapies (27,32,33).…”

This longitudinal study evaluated the response to periodontal treatment by subjects infected with either JP2 (n ‫؍‬ 25) or non-JP2 (n ‫؍‬ 25) Aggregatibacter (Actinobacillus) actinomycetemcomitans. Participants were treated during the first 4 months by receiving (i) scaling and root planing, (ii) systemic antibiotic therapy, and (iii) periodontal surgery. Probing depth (PD), clinical attachment level (CAL), and gingival and plaque indices (GI and PI, respectively) were monitored at baseline and at 12 months, along with DNA-PCR-based subgingival detection of JP2 or non-JP2 A. actinomycetemcomitans. At baseline, PD, CAL, and GI scores were statistically higher in the JP2 strain-positive group than the non-JP2-strain-positive group. At 12 months, PD, CAL, and GI scores had decreased significantly for both groups, but the reduction rates of PD and CAL were higher in the non-JP2-strain-positive group. Among JP2-strain-positive patients in the baseline, patients who remained JP2 strain positive at 12 months showed significantly higher GIs than did the patients who had lost the detectable JP2 clone. Patients who remained JP2 strain positive at 12 months appeared to be more resistant to mechanical-chemical therapy than did those who were still non-JP2 strain positive, while the elimination of JP2 A. actinomycetemcomitans remarkably diminished gingival inflammation. Early identification and elimination of the JP2 clone of A. actinomycetemcomitans will enable practitioners to effectively predict the outcome of treatments applied to periodontal patients.Compared to gingivitis, or disease-free periodontium, an increased incidence of Aggregatibacter (Actinobacillus) actinomycetemcomitans has been reported in the lesions of localized aggressive periodontitis (LAP) or severe chronic periodontitis (9,13,16,41,44,45). It is also true that while polymicrobial infection is implicated in the pathogenesis of chronic adult periodontitis, oral colonization by A. actinomycetemcomitans is more directly associated with the pathogenesis of LAP. Such pathogenic outcomes related to A. actinomycetemcomitans infection seem to be partially derived from leukotoxin (LTX) produced by A. actinomycetemcomitans. LTX is a potent virulence factor, which is encoded in an operon consisting of four genes (5) and typically causes cytotoxicity in neutrophils (26) and macrophages (37). Furthermore, in vitro experiments revealed that a specific 530-bp sequence in the LTX promoter region, rather than the LTX operon, impacts the transcription regulation of LTX (5), whereas there are several factors that regulate the expression of LTX from A. actinomycetemcomitans (25). It is also true that there may be highly leukotoxic A. actinomycetemcomitans strains other than just the type with the 530-bp deletion (24). Nonetheless, the deletion of this 530-bp promoter region, which is found in some pathogenic strains of A. actinomycetemcomitans, also called JP2 strains, has critical ramifications. For example, faster expression of the LTX gene with the deletion has been o...

Abstract: The sonic scaler system and S/RP seem to provide similarly favourable periodontal healing results, although in deep pockets S/RP appeared to achieve a better resolution of inflammation.
