The aim of this study is to examine patterns in age-related changes in LCS and factors associated with LCS.MethodsIn total, 554 children aged 3–12 years participated in this study. They had no serious dental caries and no lip or mandibular dysfunction. We measured the children's LCS with a force device, and their parents completed a 24-item questionnaire. Statistical analyses were performed using the unpaired t-test and Pearson's correlation coefficient test.FindingsLCS increased significantly from 3 to 6 years of age, but reached a plateau phase from 7 to 12 years of age. Between the ages of 3–12 years, LCS rapidly increased until infancy in a similar trajectory to the general type observed in Scammon's growth curve. In the 3 to 6-year-old age group, the correlation coefficient between “Age” and LCS was higher than between other items, and “Gender” and “Drinking liquid during meals” moderately correlated with LCS in ...

We present the case of an adult patient with cherubism, who underwent dental extraction due to chronic apical periodontitis, at a bony site that was involved with a lesion in the affected jaw. A 19-year-old woman with cherubism, exhibiting severe bilateral expansion of the lower jaw, had a decayed second molar present in a lesion of her affected mandible. Although she had reached adulthood, it was unclear if active growth of the lesion had been arrested. On removal, the tooth showed osseous ankyloses and required root separation. Postoperative healing was normal and without complications, such as wound infection and regrow...

Publication date: Available online 4 December 2019Source: Journal of Herbal MedicineAuthor(s): Farkash Yosi, Feldman Mark, Ginsburg Isaac, Shalish Miriam, Steinberg DoronAbstractDental biofilm is recognized as the primary cause of oral infections, caries being the most common. Orthodontic appliances might increase the risk for dental caries and white spot lesions. Phytomedicinal methods were shown to inhibit dental biofilm formation. The goal of this study was to examine whether Padma hepaten (PH), a polyphenolic formula derived from traditional Tibetan medicine, could inhibit the caries-inducing properties of S. mutans. B...

Abstract Aims: Matrix metalloproteinases (MMPs) are a group of calcium-dependent zinc-containing proteinases acting both physiologically and in pathological conditions. The aim of this study was to evaluate the concentration of MMP-2, MMP-8, and MMP-9 and their inhibitors TIMP-1 and TIMP-2 of unstimulated whole saliva (UWS) in correlation with the oral health in juvenile idiopathic arthritis (JIA) children. Methods: The study population comprised 34 JIA patients and 34 age- and sex-matched controls (C). They were divided into two groups: with mixed dentition (MD) and with permanent dentition (PD). Dental cari...

Abstract The present study aimed at investigating the influence of norspermidine on the formation of dual-species biofilms composed of Streptococcus mutans (S. mutans) and Streptococcus sanguinis (S. sanguinis). Crystal violet assay was conducted to assess the formation of single-species biofilms of S. mutans and S. sanguinis, and the growth curve was carefully observed to monitor the growth of these two species of bacteria. Fluorescence in situ hybridization (FISH) and MTT array were used to analyze the composition and metabolic activity of the dual-species biofilms, respectively. Extracellular polysaccharides (E...
