Dental markers of biocultural sex differences in an early modern population from Gothenburg, Sweden: caries and other oral pathologies.

Background: With the aim to study dental pathological lesions in an early Swedish modern population, with special reference to sex variances of dental caries, the prevalence and distribution of dental caries and tooth wear were determined in complete and partial human dentitions from an early modern-time city graveyard (1500-1620) excavated in Gamlestaden, Gothenburg, Sweden.

Methods: Partial and complete dentitions were examined through visual inspection and using a dental probe. Pathologies were studied, evaluated and presented by teeth and alveoli.

Oral Colonisation after the Administration of Drops Containing Lactobacillus reuteri.

Purpose: To investigate the oral colonisation potential after four weeks' administration of Lactobacillus reuteri and to examine the short-term effect of probiotics on salivary Streptococcus mutans and lactobacilli.

Materials And Methods: The study group comprised 13 young adults who volunteered after receiving verbal and written information. The short-term prospective clinical trial lasted 9 weeks, consisting of a 4-week intervention period with administration twice daily and a 5-week post-administration follow-up period with no probiotic consumption.

Effect of Lactobacillus brevis CD2 containing lozenges and plaque pH and cariogenic bacteria in diabetic children: a randomised clinical trial.

Objective: The short-term effect (60 days) of Lactobacillus brevis CD2 lozenges vs placebo on variables related to caries and gingivitis in type 1 diabetic children was evaluated.

Validation of caries risk assessment methods in orthodontic patients.

Introduction: Dental caries is an undesirable side effect of orthodontic treatment with fixed appliances. Caries lesions can result in long-term esthetic disturbance, costly interventions, and even interrupted treatment. Therefore, it is crucial to assess accurately both a patient's caries risk before treatment and their suitability for orthodontic treatment.

Equine saliva components during mastication, and in vivo pH changes in the oral biofilm of sound and carious tooth surfaces after sucrose exposure.

Background: The role of saliva composition and dietary sugar in development of infundibular caries in equine cheek teeth is not fully understood. This study analysed electrolyte and urea concentrations in saliva in relation to different forage and measured pH changes after sucrose application in vivo in sound and carious cheek teeth.

Results: Forage type had no effect on the equine saliva electrolyte concentrations, which varied considerably both intra- and inter-individually.
