Background and objective Glass ionomer cement (GIC), also known as polyalkenoate cement, has been extensively used in dentistry for both luting and restorative purposes. Despite being the first choice for aesthetic restorations due to their chemical bonding ability to teeth, GICs have faced challenges such as low mechanical properties, abrasion resistance, and sensitivity to moisture, leading to the search for improved materials.  This study aims to assess the effects of thermocycling on the compressive, flexural strength, and microhardness of green-mediated nanocomposite-modified GIC in comparison to traditional GIC...

OBJECTIVES: Fibula free flaps (FFF) are the standard approach to mandibular reconstruction after partial resection, with the goal of restoring aesthetics and masticatory function. The graft position affects both and must be carefully selected. Correlations between sagittal positioning and upper airway anatomy are known from orthognathic surgery. This study aims to evaluate changes in mandibular position and upper airway anatomy after reconstructive surgery with FFF and corresponding correlations...

BACKGROUND: This study aims to present a case of deep cervicofacial abscesses and demonstrate the efficacy of CT-guided drainage with a custom-designed puncture guide in a challenging anatomical location. The use of this type of guide is an innovative technique since CAD-CAM technology has not been used for this type of application until now. MATERIAL AND METHODS: A 76-year-old man with persistent facial swelling and trismus underwent surgical drainage initially, but symptoms persisted...

At present, the commonly used clinical protocols of oral cosmetic restoration are mostly based on the oral aesthetic indexes proposed by Western developed countries (referred to as Western aesthetics), which are different from the oral aesthetic indexes unique to Chinese people (referred to as Chinese aesthetics). In the design of restoration schemes and the evaluation of restoration effects, these differences have a large or small effect on the doctor-patient-technology triad. Improper handling could directly weaken the cooperation efficiency of the three parties, reduce patient satisfaction, and even lead to medical disputes in serious cases...

Zirconia crown has been widely used in the field of prosthodontics. Traditional zirconia exhibits excellent mechanical properties but lacks translucency. The introduction of transparent zirconia significantly enhances its aesthetic performance. In clinical applications, factors affecting the aesthetic results of full zirconia crown should be comprehensively considered, and the most suitable restoration should be chosen. Additionally, clinicians need to design appropriate tooth preparation dimensions and methods based on an individual patient's actual situation...

Cemento-ossifying fibroma (COF) is a mesenchymal benign odontogenic tumor, which may lead to impacted or ectopic permanent teeth. Autotransplantation of teeth is a surgical process, in which a tooth is transplanted from one position to another in the same individual. This method can effectively restore the patient's mastication and aesthetics and is feasible in replacing missing teeth. This study reports a case of simultaneous COF resection combined with heterotopic canine autotransplantation to repair dentition defect, which effectively promotes the restoration of bone continuity and stability and achieves immediate and long-term aesthetic function requirements...

OBJECTIVES: This study aims to evaluate the correlation between differences in intraoperative jumping gaps and soft tissue changes around immediate implant placement and provisionalization (IIPP) in the maxillary anterior region. Results will provide a basis for clinical evaluation of the change trend and long-term stability of the labial soft tissue contours of patients with different jumping gaps. METHODS: Thirty-two patients with single tooth loss in the maxillary aesthetic area were enrolled, and they all received immediate implant placement and restoration...

Crown replacement has remained one of the difficult methods for installing fixed prosthesis but is often performed because of aesthetic factors and invasion of biological width. This article focuses on the clinical scenario in which preexisting crown margin has defects. Given that clinical decisions regarding restoration management and perio-dontal tissues have to be made with caution, a decision tree of the decision making process for natural abutments in aesthetic area with preexisting defected crown margin is presented...

Orthodontics is a discipline that is based on aesthetics. It coordinates the relationship among nose, lip, and chin through the movement of teeth and the adjustment of jaw relationship. Orthodontists need to fully analyze the patient's soft tissue profile before treatment. They also need to analyze the existing problems and those that may be solved or caused during orthodontics to guide the design of orthodontic treatment and effectively improve the clinical effect of orthodontics. This article reviews the aesthetic preconditions that guide the design of orthodontic treatment from the perspective of orthodontists...

In the dental field, the specialty of prosthodontics stands out as the frontline of innovation, continually pushing the boundaries to enhance both function and aesthetics for optimal oral rehabilitation [...].

AIM: Traumatic dental injuries (TDIs) among children and adolescents have been acknowledged as of public health concern worldwide. The aim of the study was to assess the relationship between contextual and individual characteristics and TDIs in 12-year-old schoolchildren. MATERIALS AND METHODS: A cohort study was conducted with 355 schoolchildren living in deprived communities in the city of Manaus, Brazil. Contextual factors (place of residence and socio-economic indicators) and individual characteristics, including sex, family income, parents/guardians years of schooling, overjet and open bite (Dental Aesthetic Index), self-esteem (Rosenberg Self-Esteem Scale), sense of coherence (Sense of Coherence Scale), oral health beliefs, social support (Social Support Appraisals) were assessed at baseline...

The frenum is a mucous membrane fold that connects the lip and cheek to the gingiva, periosteum, and alveolar mucosa. When the frena are linked too closely to the gingival border, there may be issues with plaque removal, and the overall gingiva may be affected. In addition, the maxillary frenum may provide aesthetic difficulties or interfere with the aesthetic outcome in cases of midline diastema, which may result in a recurrence after treatment. A labial frenectomy, a frequently performed surgical operation in the specialty of dentistry, is used to address such an abnormal frenum...

PURPOSE: To evaluate the self-perceived oral health and aesthetics of the dentition and jaw in patients with different types of oral cleft, measured by patient-reported outcome measures (PROMs). Additionally, to compare the results of the PROMs between cleft lip and or/palate (CL/P) patients and non-affected controls. METHODS: 420 CL/P patients treated at the cleft team of the Erasmus Medical Center, Rotterdam, The Netherlands, were included, and 138 non-cleft patients were recruited as control-group...
