Digital versus conventional impressions for full-coverage restorations

February 2018
The primary objective of this systematic review was to investigate the survival of full-coverage restorations fabricated by using digital impressions (DIs) versus that of those fabricated by using conventional impressions. The authors also compared secondary outcomes of marginal and internal fit and occlusal and interproximal contacts. The authors conducted a systematic literature search in multiple databases to identify clinical trials with no restrictions by publication type, date, or language. The authors assessed study-level risk of bias and outcome-level strength of evidence. The authors performed a meta-analysis by using a random-effects model.

Key Words. Crowns survival; CAD-CAM; marginal adaptation; internal fit; systematic review; meta-analysis.

Bleeding frequency of patients taking ticagrelor, aspirin, clopidogrel, and dual antiplatelet therapy after tooth extraction and minor oral surgery

February 2018
Perioperative bleeding complications of ticagrelor, a newer oral antiplatelet, has not been studied in dentistry. Studies about bleeding status after oral surgical procedures in patients receiving continued antiplatelet therapy are also limited. We investigated the effects of continuing aspirin, clopidogrel, ticagrelor, or dual antiplatelet therapy on the frequency of bleeding events in patients undergoing tooth extractions or minor oral surgery. In this retrospective study, patient demographic characteristics, medical history, type of antiplatelet therapy, dental procedures, and perioperative bleeding associated with tooth extraction or other minor oral surgical procedures were obtained from the dental records of 222 patients. Bleeding was classified as normal, mild, moderate, or severe.

Key Words. Bleeding; dual antiplatelet therapy; surgery; tooth extraction; aspirin; clopidogrel; ticagrelor.

Intimate partner violence screening in the dental setting

February 2018
The dental setting is a potential venue for identifying patients experiencing intimate partner violence (IPV). The study objective was to assess dentists’ current practices and attitudes about IPV screening. A nationally representative survey of US general dentists assessed dentists’ use of health history forms that queried about IPV and their acceptance of IPV screening as part of their professional roles. Parsimonious Poisson regression models were used in multivariable analysis to estimate risk ratios for the 2 dependent variables.

Key Words. Intimate partner violence; oral health; screening.

Surface characteristics and lesion depth and activity of suspicious occlusal carious lesions

December 2017
A lesion on an occlusal tooth surface with no cavitation and no radiographic radiolucency but in which caries is suspected owing to surface roughness, opacities, or staining can be defined as a suspicious occlusal carious lesion (SOCL). The authors’ objective was to quantify the characteristics of SOCLs and their relationship to lesion depth and activity after these lesions were opened surgically. Ninety-three dentists participated in the study. When a consenting patient had an SOCL, information was recorded about the tooth, lesion, treatment provided, and, if the SOCL was opened surgically, its lesion depth. The Rao-Scott cluster-adjusted c2 test was used to evaluate associations between lesion depth and color, roughness, patient risk, and luster.

Key Words. Evidence-based dentistry; carious lesions; dentin.

Efficacy of adjuvant laser therapy in reducing postsurgical complications after the removal of impacted mandibular third molars

December 2017
The authors updated a previously published systematic review to assess the effects of low-level laser therapy (LLLT) on reducing complications after the removal of impacted mandibular third molars. The authors searched for randomized clinical trials in which the investigators evaluated the efficacy of LLLT compared with that of placebo or no treatment. Two reviewers independently screened studies, extracted data, and assessed risk of bias. The authors used random effects model meta-analysis and the Grading of Recommendations Assessment, Development and Evaluation approach to rate the certainty of evidence.

Key Words. Impacted mandibular third molar; systematic review; postsurgical complications; pain; swelling; trismus.

Dental disease before radiotherapy in patients with head and neck cancer

December 2017
No evidence-based guidelines exist for preventive dental care before radiation therapy (RT) in patients with head and neck cancer (HNC). An ongoing multicenter, prospective cohort study, Clinical Registry of Dental Outcomes in Head and Neck Cancer Patients (OraRad), is addressing this knowledge gap. The authors evaluated the level of dental disease before RT in the OraRad cohort, factors associated with dental disease, and dental treatment recommendations made before RT. As part of OraRad, the authors assessed caries, periodontal disease, dental recommendations, and dental interventions performed before RT.

Key Words. Radiation therapy; dentistry; caries; periodontal diseases; head and neck neoplasms.
