Study summary

This study is a cohort investigation involving patients scheduled to receive dental implants in edentulous sites adjacent to natural teeth. Individuals aged between 18 and 65 years, without any systemic diseases and possessing natural teeth adjacent to the planned implant sites, were included. Clinical and radiographic evaluations were conducted preoperatively, and at 1 week, 1 month, and 3 months following implant placement. The null hypotheses (H0) of this study are as follows: First, there is no significant difference in the clinical parameters of adjacent teeth before and after implant surgery. Second, there is no significant change in the radiological parameters in adjacent teeth between the preoperative and postoperative periods.

Read the detailed description

Modern implantology began in 1965 with the placement of four intraosseous titanium implants in a patient with a mandibular defect, marking the introduction of the concept of osseointegration. Since then, dental implants have emerged as a reliable and effective treatment modality for the rehabilitation of edentulous spaces. This longitudinal cohort study aims to evaluate whether dental implants placed in edentulous sites adjacent to natural teeth lead to alterations in the endodontic condition of these neighboring teeth. Specifically, the study investigates the nature and extent of any pulpal or periapical changes in adjacent teeth following implant placement. It is hypothesized that any damage to the adjacent teeth may be attributed to intraoperative complications, iatrogenic factors, or physiological consequences associated with the healing of hard and soft tissues post-surgery. The short-term observation intervals (1 week, 1 month, and 3 months postoperatively) are expected to offer insights into the potential causes of endodontic symptoms that may arise in neighboring teeth. Through this design, the study seeks to better understand the etiological relationship between implant placement and the pulpal/periapical health of adjacent teeth.

Groups and cohorts

  • Patients scheduled for implant placement in edentulous sites adjacent to natural teeth

    Patients scheduled to receive multiple implants at different time points, in edentulous sites adjacent to natural teeth, based on individualized surgical planning.

    Diagnostic Test: Clinical and radiographic examination

Interventions

  • Diagnostic testClinical and radiographic examination

    In order to evaluate the pulpal and periapical health of natural teeth adjacent to dental implants at specific time intervals, percussion, palpation, and pulpal diagnostic tests were performed, and the presence of any pathological changes was monitored using radiographic examinations.

What researchers measure

Primary outcomes

  1. Percussion and Pulpal Diagnostic Test Outcomes

    At the preoperative stage and during postoperative follow-ups at 1 week, 1 month, and 3 months, vertical percussion was performed on the natural teeth adjacent to the dental implant by gently placing a dental probe under its own weight. The response was recorded as either positive or negative. Electric pulp test and cold test (pulpal diagnostic tests) were also performed on the adjacent teeth at the same time intervals. Numerical responses were recorded for the electric pulp test, while responses to the cold test were documented as either positive or negative.

    Time frame: At the preoperative stage and during postoperative follow-ups at 1 week, 1 month, and 3 months the tests were performed.

  2. Palpation Test Outcomes

    To assess the presence or absence of tenderness upon palpation, a bidigital palpation test was performed during the preoperative phase and at postoperative follow-up visits at 1 week, 1 month, and 3 months. The response was recorded as either positive or negative.

    Time frame: At the preoperative stage and during postoperative follow-ups at 1 week, 1 month, and 3 months the tests were performed.

  3. Measurement of pain scores using the Numeric Pain Rating Scale (NPRS)

    At the preoperative stage and during postoperative follow-ups at 1 week, 1 month, and 3 months, patients were asked to indicate the number corresponding to the intensity of pain they experienced on a 0-10 Numerical Rating Scale (NRS), and the selected values were recorded.

    Time frame: At the preoperative stage and during postoperative follow-ups at 1 week, 1 month, and 3 months the tests were performed.

  4. Assessment of Radiological Outcomes

    Periapical status of the natural teeth adjacent to the dental implants was assessed radiographically at baseline and at the 3-month postoperative follow-up. Radiographs were evaluated for the presence of any periapical pathology, and outcomes were documented as either 'radiolucent area present' or 'radiolucent area absent'.

    Time frame: At the preoperative stage and during postoperative follow-up at 3 months the tests were performed.
