Clinical parameters and bacteriological evaluation of Acess® as a periodontal therapeutic toothpaste: a non-blinded randomized clinical trial

Purpose: The objective of this prospective randomized clinical trial (RCT) was to analyze and compare the clinical behavior of three types of prosthesis supported by single implants in the posterior region after three years of functional loading. Materials and methods: Seventy-five implants were divided into three groups according to the type of prosthetic restoration: screw-retained crown (group GS); cemented crown without finishing line (biologically oriented preparation technique) (group GBOPT); and conventional cemented crown with finishing line (group GCC). After three years in function, clinical parameters (presence of keratinized mucosa, probing depths, bleeding on probing, and radiographic bone loss) were compared between the three experimental groups. The possible correlation between soft tissue clinical parameters and bone loss was also analyzed. Results: Statistical analysis found significant differences in clinical parameters between the different types of crown, with the cemented restoration without finishing line (BOPT) presenting fewer complications and better peri-implant health outcomes including: significantly different KMW data (mm), with significant differences between groups GBOPT and GCC (p < 0.001, Kruskal–Wallis test), with GBOPT obtaining larger quantities of keratinized mucosa (KM); statistically significant differences in probing depth (PD) values between groups GBOPT and GCC (p = 0.010, Kruskal–Wallis test); significant differences in bleeding on probing (BOP) between groups GBOPT and GCC (p = 0.018, Chi2 test) in favor of GBOPT. Conclusions: Soft tissue behavior around implants is related to the type of prosthetic restoration used, with cemented prostheses with BOPT presenting better peri-implant soft tissue behavior.

Root Planing

BACKGROUND & AIM: Photodynamic therapy is a localized non-invasive treatment modality for the periodontal disease. Some evidences have shown that this technique is effective in improving the treatment outcome. This study compared the effects of photodynamic therapy with and without scaling and root planing and scaling and root planing alone on the clinical parameters of the chronic periodontitis.MATERIALS & METHODS: In this single-blind, randomized clinical trial, 30 chronic periodontitis patients (10 for each modality) were selected and three different methods; photodynamic therapy alone (Group1) by FotoSan 630 system, scaling and root planning (SRP) alone (Group2), scaling and root planing combined with photodynamic therapy (Group3) were done for them randomly. Clinical parameters of probing pocket depth (PPD), bleeding on probing (BOP), and clinical attachment level (CAL) were measured at the baseline and 3, 6 and 12 weeks later. One-sided analysis of variance test was used to analyze PPD and CAL among the treatment groups in each time interval while the paired comparisons were carried out by employment of Dunnett’s test. The treatment groups were statically analyzed by the chi-square test regarding BOP. RESULTS: Before the treatment; no significant differences observed among treatment modalities regarding clinical parameters; while the differences were significant at three weeks (p<0.0001 for PPD and CAL; p<0.001 for BOP); six weeks (p<0.0001 for PPD and CAL, p<0.002 for BOP); and 12 weeks after the treatment (all: p<0.0001). The least PPD and CAL values and the most frequency of non-bleeding on probing status were measured for PDT+SRP modality at three, six, and twelve weeks after the treatment.CONCLUSION: Photodynamic therapy supported the clinical parameters of periodontitis similar to SRP; however, PDT combined with SRP demonstrated a better result than that of SRP alone. Therefore, PDT combined with SRP can be used to improve outcomes of clinical parameters of periodontitis as compared to SRP alone in the short-term.

Salivary Ph

The aim of the study is to assess the effect of pre and post Non Surgical Periodontal Therapy on Salivary pH in patients suffering with Chronic Periodontits. Patients reporting to the Department of Periodontics, I.T.S Dental College, Hospital & Research Centre, Greater Noida, Uttar Pradesh are included in the study. It is a randomized clinical trial where patients are randomized into two groups of Generalized Chronic Gingivitis and Generalized Chronic Periodontitis. The study are performed with the Sample size of 30 patients and 2 months Period were included. Unstimulated Saliva is collected at the first visit when patient reports to the OPD for NSPT. Clinical Parameters are recorded and NSPT is performed for the patient. Post 14 days of the treatment, saliva is collected and analysed for pH and clinical parameters are recorded again. pH is determined using a pH meter. Data is collected and statistically interpreted. The statistical testing to be used in this study are Mann Whitney U Test, Chi- square test and Paired t-test. There was statistically significant difference in plaque index, gingival index and oral hygiene index between two groups. There was a definite reduction in pH post SRP but it was statistically non significant due to relatively smaller sample size. Further research is required to substantiate the results for the same.
