Periodontitis is a serious gum disease caused by bacteria that form a sticky film, known as biofilm, on the teeth. This condition leads to long-lasting inflammation that the body cannot stop, resulting in damage to the tissues that support the teeth. If left untreated, periodontitis can lead to tooth loss.

Types of Treatment for Periodontitis

To manage chronic periodontitis, dental professionals often use either non-surgical or surgical methods. The goal of these treatments is to improve the health of the Gums and teeth. However, some treatments can cause side effects. For instance, some people may experience gum recession or Sensitivity in their teeth after undergoing periodontal treatments, especially if surgery is involved.

Research indicates that of patients who suffer from tooth sensitivity after treatment, a significant number have had previous periodontal procedures. This sensitivity can sometimes linger for months or even longer, causing discomfort for many individuals. Unfortunately, there is limited research focused on how to treat this sensitivity effectively.

The Role of Lasers in Treating Tooth Sensitivity

One approach that has been suggested to alleviate tooth sensitivity is Laser Treatment. Although the exact way lasers help in this regard isn’t fully understood, there are several theories. High-powered lasers can heat up and effectively close off the tiny tubes in the teeth called dentinal tubules, reducing sensitivity. Low-intensity lasers may promote healing in the dental pulp, which could also help in making the teeth less sensitive by encouraging the growth of protective dentin.

Low-power lasers are often preferred because they are generally safer, do not produce heat, and are easier for dental professionals to use.

Study Objective

The goal of this study is to evaluate how effective low-power lasers are at reducing tooth sensitivity following treatments that involve scaling and root planning in patients with periodontitis.

Study Design

This research will be a randomized, controlled trial involving two groups of patients, where neither the patients nor the researchers know which treatment each patient is receiving. The study has been approved by an ethics committee and has been registered in a clinical trial database.

Patients who are over 18 years old and need periodontal treatment will be selected for this study. Only those without certain serious health conditions or medications that could affect their gums will be included. Each participant will give written and verbal consent to be part of the study.

How Participants Will Be Selected

Patients coming to the dental clinic with a diagnosis of periodontitis will first go through an initial treatment phase that includes instruction on proper oral hygiene and cleaning procedures. After a week, their gum sensitivity will be assessed. Those who report Pain will enter the study.

Group Allocation

A total of 44 patients will be involved, divided into two groups with 22 patients each. The first group will receive the real laser treatment, while the second group will undergo a simulated treatment where no real laser application is done but the procedure will appear the same. This will help ensure that any results observed can be attributed to the laser treatment.

Training of Researchers

Those carrying out assessments will be trained to ensure that they collect data accurately. A system will be put in place to randomly assign patients to the two treatment groups, and this process will be managed by someone who does not interact with the patients or the treatments.

Immediately after the initial treatments, one of the researchers will carry out the assigned procedure based on the randomization. Only this researcher will know which treatment each patient receives, while others involved in the research will remain unaware of this information.

Assessing Patient Sensitivity

Before treatments, patients will be asked about their medical history and will undergo a thorough examination. They will also receive instructions on how to care for their teeth. After one week, their sensitivity will be assessed once again.

Measurement of Pain

Pain levels will be measured using a simple scale that goes from no pain to unbearable pain. Patients will mark on a ruler how much pain they feel, and this information will be recorded for analysis on various days throughout the study.

Monitoring Medication Use

In addition to measuring pain, the study will also track how much pain medication participants take. Each patient will receive a pack of pain relievers at the beginning of the study, and researchers will check how many pills have been used by the end of the study.

A questionnaire will also be used to gather information on how dental health affects the patients' quality of life. This will help understand the broader impact of dental treatments on daily living.

Data Collection and Analysis

The study will collect both numerical data and feedback from participants about their experiences. Once all data is gathered, the researchers will analyze it to see if there is a significant difference between the two treatment groups. They will use accepted statistical methods to interpret the findings and look for any potential side effects that may occur during the study.

Researchers will be vigilant about any adverse events and will check in with participants regularly. Because the study does not expect complications from the treatments, there will be no interim assessments unless necessary.

Conclusion

This research aims to shed light on the effectiveness of laser therapy for treating tooth sensitivity related to periodontal treatments. With clear protocols and a focus on patient care, the study hopes to provide valuable insights that could improve treatment approaches for those suffering from gum diseases and related sensitivity issues.

Title: Evaluation of tooth sensitivity after scaling and root planing treated with photobiomodulation: a randomized controlled split-mouth double-blind clinical protocol

Abstract: It is well known that hypersensitivity affects patients recently treated with scaling and root planing. Some studies have demonstrated that photobiomodulation (PBM) can alleviate dentinal hypersensitivity by modulating pain. However, to date, there is no established protocol for its application after scaling and root planning. To evaluate tooth hypersensibility after photobiomodulation in sensitive scaling and root planning treated teeth. Study design: Randomized, controlled, double-blind split-mouth clinical trial. Methods: Forty-four patients with dentin sensibility after non-surgical scaling and root planning (SRP) will be randomly included in 2 groups: Experimental Group: SRP+ Photobiomodulation (PBM) (660nm, 100W, area 0,5cm2, 200w/cm2, 30 seconds, 3 J, 6J/cm2) and Control Group: Scaling and root planning +FBM simulation. After 7 days of scaling and root planning, all patients will be evaluated for hypersensibility. The cutoff of VAS will be 3. These patients will be included in the study. The primary outcome of the study will be the assessment of dentin hypersensitivity after 7 days of RAR measured with the visual analog scale (VAS). Also, it will be assessed the impact of oral health on the participants quality of life, with the OHIP-14 questionnaire. The use of analgesics (paracetamol) will be prescribed as needed and the amount of medication will be calculated. These outcomes will be evaluated after 7 days and 1 month of application. If the data are normal, they will be submitted to the ANOVA test - one way. Data will be presented as means {+/-} SD and the p-value will be set to < 0.05.
