Adjunctive Diode Laser Therapy and Probiotic Lactobacillus Therapy in the Treatment of Periodontitis and Peri-Implant Disease

Summary

This article describes two protocols: 1) adjunctive diode laser therapy for treating periodontitis and 2) probiotic Lactobacillus therapy for treating peri-implant disease, with emphasis on the laser usage mode (inside or outside pocket), laser application regimen (single or multiple sessions), and a probiotic protocol of professional and home administration.

Abstract

Periodontal and peri-implant diseases are plaque-induced infections with a high prevalence, seriously impairing people's quality of life. The diode laser has long been recommended as adjunctive therapy in treating periodontitis. However, the optimal combination of usage mode (inside or outside periodontal pocket) and application regimen (single or multiple sessions of appointment) has not been described in detail. Meanwhile, probiotic Lactobacillus is regarded as a potential adjuvant in the management of the peri-implant disease. Nonetheless, a detailed protocol for an effective probiotic application is lacking. This article aims to summarize two clinical protocols. For periodontitis, the optimal collaboration of laser usage mode and application regimen was identified. Regarding peri-implant mucositis, a combined therapy containing professional topical use and home administration of probiotic Lactobacillus was established. This updated laser protocol clarifies the relationship between the treatment mode (inside or outside the periodontal pocket) and the number of laser appointments, further refining the existing diode laser therapy. For inside pocket irradiation, a single session of laser treatment is suggested whereas, for outside pocket irradiation, multiple sessions of laser treatment provide better effects. The improved probiotic Lactobacillus therapy resulted in the disappearance of swelling of the peri-implant mucosa, a reduced bleeding on probing (BOP), and an obvious reduction and good control of plaque and pigmentation; however, probing pocket depth (PPD) had limited improvement. The current protocol should be regarded as preliminary and could be further enhanced.

Introduction

Periodontal disease is a chronic multifactorial infection resulting in progressive destruction of periodontium¹. Its severe form, periodontitis, affects up to 50% population worldwide² and is regarded as a major cause of tooth loss in adults³. Replacement of missing teeth with dental implants has been extensively favored over traditional options⁴. The implants show prominent functional and aesthetic performances with a long-term survival rate of 96.1% after 10 years^5,6. The implants, however, can suffer from peri-im....

Protocol

This study was approved by the Institutional Review Board of the College of Stomatology, Xi'an Jiaotong University (xjkqll[2022]NO.034). Informed consent was available from the patients involved in this study.

1. Adjunctive diode laser therapy in the non-surgical treatment of periodontitis

1. Eligibility criteria
   1. Use the following inclusion criteria: age ≥ 18 years; probing pocket depth (PPD) ≥ 5 mm; detectable clinical attachment loss (CAL.......

Discussion

Although diode laser has been widely utilized in periodontal therapy, the clinical effectiveness remains controversial among current clinical trials^15,20. As demonstrated, the laser usage mode and application regimen have significant impacts on the efficacy of periodontal laser therapy¹². Most researchers, however, ignore the potential role, eliciting results that are hard to explain. Under different usage modes, excessive or insufficient .......
