This paper reports an implant periapical lesion (IPL) with a previously unreported etiology. The presence of an osteolytic area around the apex and around the middle portion of a stable Straumann hollow-screw implant was found on periapical radiographs 3.5 years after implant placement. Case management involved curettage of the soft tissue surrounding the implant apex as well as resection of the nonosseointegrated portion of the implant. Histopathologic examination revealed a connective fibrous tissue containing a dense chronic inflammatory infiltrate with a foreign-body material. Polarized light microscopy and Fourier transform infrared microspectroscopy identified the foreign-body material as starch particles. Etiology of this IPL was thus related to a foreign-body reaction to starch particles. This exogenous contamination probably originated from starch-coated gloves during the surgical procedure. This case report suggests that IPL may successfully be treated by debridement and implant resection instead of implant removal. Peri-implant apical soft tissue should be systematically submitted for histopathologic examination.

Objectives: This meta-research assessed methodologies used for evaluating peri-implant marginal bone levels on digital periapical radiographs in randomised clinical trials published between 2019 and 2023.
Methods: Articles were searched in four databases. Data on methods for assessing peri-implant marginal bone levels were extracted.

Background: To minimize the risk of impaired osseointegration historically, it has been recommended to insert the implant into the bone (submerged implants) and to allow for submerged healing of 3-6 months in the lower and upper jaw, this conventional technique is advocated. The concept of nonsubmerged healing was introduced in 1988 in which gingival former was placed at the time of implant placement instead of cover screw. The treatment concept of nonsubmerged implant placement enables early implant loading, one surgical procedure only, and a reduced treatment period for the patients.

Background: Chronic apical periodontitis (AP) may influence the outcome of root canal treatment. Thus, it is important to diagnose AP using the best method available. This research was done to compare the diagnostic accuracy of parallel periapical radiography (PR) and different field of views (FOVs) of cone-beam computed tomography (CBCT).

Objectives: Nonsteroidal anti-inflammatory drugs (NSAIDs) are often prescribed following the placement of dental implants, but the effects of these drugs on the osseointegration process are poorly understood. We designed a randomized, placebo-controlled pilot study to quantitatively assess the effect of NSAIDs during early implant osseointegration.
Materials And Methods: Subjects receiving a maxillary dental implant were randomized to take naproxen or placebo for 7 days after the surgery.
