Assessment of Proximal Protection Usage by Dental Students During Class II Cavity Preparations: An In Vivo Pilot Study.

Background: Class II cavity preparations in restorative dentistry pose a risk of iatrogenic damage to adjacent teeth as they could increase their susceptibility to caries and the need for additional restorative procedures. While previous research has explored this issue through in vitro and limited in vivo investigations, the direct clinical observation of proximal protection usage to prevent iatrogenic damage during class II cavity preparations is still limited.

Aim: This in vivo study aimed to assess the prevalence of proximal protection usage and extent of iatrogenic damage induced to adjacent surfaces upon occurrence during class II cavity preparations via direct visual inspection under magnification.

Knowledge and Attitude Toward Esthetic Dentistry and Smile Perception.

Introduction: A smile is important in human communication and is increasingly valued in modern society. The perception of smile attractiveness is subjective and depends on many factors.

Aim: This study aimed to evaluate and compare knowledge and attitude related to esthetic dentistry in dental students versus dental interns, general dentists, and dental specialists, examine the self-perception of their smile, and identify parameters that influence smile perception.

Efficacy of P-4 for the treatment of initial buccal caries: a randomized clinical trial.

To investigate the safety and efficacy of Self-Assembling Peptide P-4 (SAP P-4) compared to placebo or fluoride varnish (FV), a randomized, controlled, blinded, split-mouth study with sequential design was conducted. Subjects presenting two teeth with White-Spot-Lesions (WSLs) were included and teeth were randomly assigned to test or control. Control received placebo at baseline (D0) and test SAP P-4, all received FV at Day 90 (D90).

Caries-risk profile variations after short-term use of 5000 ppm fluoride toothpaste.

Objective: To assess the caries risk following 6 weeks' use of 5000 ppm F toothpaste using 'Cariogram' software.

Materials And Methods: A total of 34 participants, 17 mothers and their teenage children, were enrolled in a 6-week clinical trial in which they were given 5000 ppm F toothpaste. They were followed consecutively for 6 weeks with visits that were 2 weeks apart (four in total).

Effects of high-fluoride dentifrice (5,000-ppm) on caries-related plaque and salivary variables.

Objectives: The aim of the present study was to measure the effects of a 5,000-ppm F toothpaste on caries-related factors in dental plaque and saliva.

Materials And Methods: A 6-week clinical trial was designed with a total of 34 participants, of which 26 completed the study. The participants were assessed on four visits, 2 weeks apart.

Supragingival plaque microbial analysis in reflection to caries experience.

Background: Dental caries develops as a result of the metabolism of carbohydrates by cariogenic bacteria present in a complex biofilm. The present study aimed to examine if bacteria in pooled supragingival plaque samples quantified using a "checkerboard DNA-DNA hybridization" based panel of caries-related bacteria, could reflect the caries experience in a manner similar to saliva samples analysed using a chair-side method in a previous investigation.

Methods: A total of 86 mothers and their children aged 4-6 years and 12-16 years old participated.

Intra-familial comparison of supragingival dental plaque microflora using the checkerboard DNA-DNA hybridisation technique.

Objective: The aims of the present study were to correlate the quantified supragingival plaque bacteria between mothers and their children and identify possible microbial associations.

Design: A total of 86 mothers and their 4- to 6-year-old and 12- to 16-year-old children participated. Pooled supragingival plaque samples were obtained from interproximal sites between teeth 16/15, 25/26, 35/36 and 46/45 in mothers and older children and teeth 55/54, 64/65, 74/75 and 85/84 in younger children.
