STATEMENT OF PROBLEM: The gingival zenith (GZ) influences the line angle position in the emergence profile and the axial inclination of the crown. Irregularities in GZ symmetry and contour have a negative impact on dental esthetics. GZ location is not consistently distal to the crown's long axis; instead, it tends to be more distal in anterior teeth. The GZ levelling of the lateral incisor is often described as either level with or slightly above the zenith line connecting the central incisor and canine teeth, but there are also reports of GZ being aligned apically to the zenith line...

STATEMENT OF PROBLEM: Silicone elastomers are becoming more readily available for additive manufacturing, which may be advantageous for fabricating maxillofacial prostheses. However, the properties of three-dimensionally (3D) printed silicone as compared with conventionally processed silicone have not been well studied. PURPOSE: The purpose of this in vitro study was to compare the dimensional accuracy and surface resolution of additively manufactured with conventional room-temperature vulcanized (RTV) silicones...

OBJECTIVES: To quantify the reproducibility of the drill calibration process in dynamic navigation guided placement of dental implants and to identify the human factors that could affect the precision of this process in order to improve the overall implant placement accuracy. METHODS: A set of six drills and four implants were calibrated by three operators following the standard calibration process of NaviDent®. The reproducibility of the position of each tip of a drill or implant was calculated in relation to the pre-planned implants' entry and apex positions...

OBJECTIVES: To evaluate the positional accuracy of implant analogs in biobased model resin by comparing them to that of implant analogs in model resin casts and conventional analogs in dental stone casts. METHODS: Polyvinylsiloxane impressions of a partially edentulous mandibular model with a single implant were made and poured in type IV dental stone. The same model was also digitized with an intraoral scanner and additively manufactured implant casts were fabricated in biobased model resin (FotoDent biobased model) and model resin (FotoDent model 2 beige-opaque) (n=8)...

OBJECTIVE: Oral status is an important indicator of past lifestyles. Determining the presence and extent of oral pathologies helps reconstruct average oral health, paramasticatory activities and diet of ancient and historical populations. DESIGN: In this study, the dental remains from the early medieval cemetery of Früebergstrasse in Baar (Canton of Zug, Switzerland) and the high medieval Dalheim cemetery (North Rhine-Westphalia, Germany) were analyzed. Caries, periodontal condition, periapical lesions, antemortem tooth loss, and enamel hypoplasia were assessed in 654 teeth (993 observable loci) from 68 individuals (Baar: n = 36; Dalheim: n = 32)...

BACKGROUND: Approximately 10% of the US population self-reports a penicillin allergy history or are labeled as penicillin allergic. However, from 90% through 99% of these patients are not allergic on formal evaluation. CASE DESCRIPTION: Patients labeled as penicillin allergic receive broader-spectrum and sometimes less-effective antibiotics, thereby contributing to increased treatment failures, antibiotic resistance, and adverse drug reactions. Self-reported penicillin allergy can be eliminated or classified as low-, medium-, or high-risk after a careful review of patient history...

OBJECTIVE: A conceptual model was designed and tested to predict immigrant children's oral health in Canada by examining parental acculturation and perceived social support (PSS) using structural equation modelling. METHODS: A convenience sample of first-generation immigrant parents and their children aged 2-12 years were recruited by multilingual community workers in Edmonton, Canada. Parents completed a validated questionnaire on demographics, child's oral health (OH) behaviours, parental acculturation and PSS...
