Digital Analysis of Dentogingival Factors Influencing the Gingival Margin Position in the Esthetic Zone.

Objectives: To investigate the correlation between gingival thickness (GT) and buccal bone thickness (BBT), as well as the effects of GT, BBT, bone crest level (BC), and tooth position on the buccal gingival margin location of maxillary teeth in the esthetic zone.

Materials And Methods: Periodontally healthy subjects with prior cone beam computed tomography and intraoral scans for dental implant planning were included. The hard and soft tissue measurements were retrospectively analyzed digitally.

Electronic periodontal tool integration to enrich clinical diagnosis.

Purpose/objectives: The objective of this study was to evaluate the effectiveness of an Electronic-Periodontal-Diagnosis-Tool (EPDT) to facilitate the formulation of a correct periodontal diagnosis and analyze students' perceptions of the use of the EPDT.

Methods: Fifty Year-3 students who recently started their clinical training, were randomly assigned to two groups. Two clinical scenarios involving challenging periodontal diagnoses, each one with unique components, variables, and categories were distributed with specific instructions.

The periodontal senior case clinical challenge: Students' opinions of a formative virtual assessment during the COVID-19 emergency.

Introduction: Due to COVID-19, innovative, virtual educational methods are being developed to provide students with learning experiences comparable to established clinical practices. Our objective was to produce the Periodontal Senior Case Clinical Challenge (PSCCC) that would provide fourth-year students an alternative for senior case presentations and would be a formative assessment for which student opinions would be provided and analysed. The PSCCC would utilise an online, case-based, written, clinical assessment and follow-up, structured discussion to challenge students to demonstrate ability to apply didactic periodontal knowledge to patient-based experiences.

Early Failure Rate and Associated Risk Factors for Dental Implants Placed With and Without Maxillary Sinus Augmentation: A Retrospective Study.

Purpose: Dental implant treatment is one of the most successful methods to replace lost teeth. However, several factors play a role in the early failure of implants, which could occur prior to the insertion of the restorative component. This study aimed to investigate the rate of early implant failure in the maxillary posterior area with and without sinus augmentation and other related risk factors.

Comparative Evaluation of SmartMouth Clinical DDS Advanced Oral Rinse and Chlorhexidine Mouthrinse.

Purpose: To evaluate the efficacy of SmartMouth Clinical DDS compared with 0.12% chlorhexidine and placebo mouthrinses.

Materials And Methods: Seventy-six subjects with gingivitis or chronic periodontitis were enrolled in a double-blind, placebo-controlled, clinical study.

Biological and Physicochemical Characteristics of 2 Different Hydrophilic Surfaces Created by Saline-Storage and Ultraviolet Treatment.

Objectives: Hydrophilicity/hydrophobicity of titanium surfaces may affect osseointegration. Ordinary titanium surfaces are hydrophobic. Recently, 2 different methods of storing titanium in saline solution or treating it with ultraviolet (UV) light were introduced to generate surface hydrophilicity.

Retrospective assessment of survival rate for short endosseous dental implants.

Purpose: The aim of this study was to determine the survival rate of short implants that were placed in a residency program. In addition, the potential influence of diabetes, smoking, sinus grafting, guided bone regeneration, and implant type on survival was analyzed.

Methods: Through a retrospective chart review, patient information and parameters for short implants being equal or less than 10 mm and regular implants being more than 10 mm were collected.

Heritability of alveolar bone loss from periodontal disease in a baboon population: a pilot study.

Background: Reports from studies of twins, disease aggregation in families, animal models for periodontal disease, and various genetic-analysis studies have determined that genetics plays a role in the susceptibility to periodontal disease. The purpose of this pilot study is to evaluate the effect of genetics on periodontal disease by evaluating the heritability of alveolar bone loss in a captive baboon population.

Methods: A collection of baboon skulls from a pedigreed colony (for which scientists and veterinarians maintain complete genealogic and veterinary records) was obtained from the Southwest National Primate Research Center, San Antonio, Texas and used in this pilot study.

One-year effects of vitamin D and calcium supplementation on chronic periodontitis.

Background: A previous study reported by this group found that patients in periodontal maintenance programs taking vitamin D and calcium supplementation had a trend for better periodontal health compared to patients not taking supplementation. The objective of the present study is to determine, for the same cohort of subjects, whether such differences persist over a 1-year period.

Methods: Fifty-one patients enrolled in maintenance programs from two dental clinics were recruited.

Abfractions and attachment loss in teeth with premature contacts in centric relation: clinical observations.

Background: It has been suggested that eccentric occlusal forces may be an etiologic factor for abfraction lesions. It has also been suggested that traumatic occlusal forces may have a damaging effect on the periodontal tissues. The purpose of this study was to determine whether associations were present between premature contacts in centric relation (PCCR), clinical attachment loss, and abfraction lesions.

Cross-sectional study of vitamin D and calcium supplementation effects on chronic periodontitis.

Background: A low dietary intake of vitamin D and calcium hastens bone loss and osteoporosis. Because vitamin D metabolites may also alter the inflammatory response and have antimicrobial effects, we studied whether the use of vitamin D and calcium supplements affects periodontal disease status.

Methods: A cohort of 51 subjects receiving periodontal maintenance therapy was recruited from two dental clinics; 23 were taking vitamin D (>or=400 IU/day) and calcium (>or=1,000 mg/day) supplementation, and 28 were not taking such supplementation.

Osseous coagulum collected in bone traps: potential for bacterial contamination and methods for decontamination.

Because of its excellent osteogenic potential, autogenous bone is the preferred grafting material for dental procedures; however, bone collected in osseous coagulum traps is subject to contamination by oral bacteria. This study assessed bacterial contamination of osseous coagulum and tested treatments for reducing contamination. Fifty bone samples from patients undergoing implant osteotomy procedures were collected in osseous coagulum traps, divided into groups of 10, and rinsed with normal saline, 0.

Full-thickness flap/subepithelial connective tissue grafting with intramarrow penetrations: three case reports of lingual root coverage.

Three case reports are presented that demonstrate the use of full-thickness flap/subepithelial connective tissue grafting for root coverage on the lingual surfaces of the mandibular anterior teeth. This is accomplished using an envelope full-thickness flap technique with intramarrow penetrations at the recipient site. Miller Class I, II, and III gingival recession defects and gingival perforation defects were treated.

The patient with diabetes mellitus: etiology, epidemiology, principles of medical management, oral disease burden, and principles of dental management.

Diabetes mellitus is an etiologically and clinically heterogeneous group of metabolic disorders that share the commonality of hyperglycemia. Long-term hyperglycemia produces tissue damage, which ultimately manifests as microvascular and macrovascular disease, and neuropathy. The presence of macrovascular disease should alert clinicians to the possibility that the patient may have coronary artery disease, particularly because coronary artery disease and myocardial ischemia are likely to be silent.
