Conservative nonsurgical treatment of mandibular central giant cell granuloma in an adolescent: A case report
Publication date: April 2014 Source:Pediatric Dental Journal, Volume 24, Issue 1 Author(s): Puneet Goyal , Ravi Narula , Shaveta Bansal , Samriti Bansal , Pratibha Garg Giant-cell reparative granuloma (GCRG) is a nonneoplastic osteolytic lesion of unknown origin that may have an aggressive imaging appearance. Although it is a benign disease process, it can be locally destructive as well. Surgery is the traditional and still the most accepted treatment for giant-cell granuloma (GCG). The purpose of this article is to report the clinical case of a 14-year-old girl with a mandibular central giant cell granuloma (CGCG), whic...

Determination of H-file sizes being more suitable for measuring of working length in immature teeth using an EAL
This study aimed to find the sizes of H-files that are more suitable for root canal length measurements of immature teeth using Apit 11®. Extracted human immature permanent teeth were prepared to have accesses to their pulp cavities, and the root canal length of each tooth was measured physically and electronically using H-files, rular and Apit 11® in the in vitro experimental system. Six types of file diameters that are generally utilised in the clinic were used to take measurements in order to observe the relationship between the position of the file tip and the meter-indicated area. The results suggest that...

Study on factors that affect caries susceptibility in mice
We examined temporal changes in stimulated saliva secretion volume in B6 and C3H mice, and found that secretion volume was significantly higher in C3H mice than in B6 mice even at 30 min after stimulation, and that total saliva volume was significantly higher in C3H mice. In addition, histological comparisons of the submandibular gland in the two strains revealed the ratio of acinar cells area to be significantly higher in C3H mice than in B6 mice. We then examined the gene expression of the muscarinic acetylcholine receptors M1R, M2R and M3R, which are thought to be regulatory factors of water secretion from acinar c...

A primary study on feeding behaviors of autism model rat pups in the weaning period
This study aimed to identify appropriate measures to address behavioral characteristics associated with eating and feeding in children with ASD by examining feeding behavior throughout the weaning period in rat pup models of autism. Male Sprague–Dawley (SD) rats and healthy SD rats were nursed with their mothers until 14 days after birth. Then, the pups were divided into the following three groups and related in separate cages without their mothers: group A, two model rats; group B, a model rat and a control rat; and group C, two control rats. The number of meals ingested together and the number of body contact made ...

A warmed topical fluoride solution enhances KOH-soluble and -insoluble fluoride formation on tooth surfaces in vitro
This study investigated the effect of warmed topical fluoride solutions on human enamel. Several solutions (acidified phosphate fluoride (APF), 2% NaF or 0.2% NaF) were applied to human premolars for 5 min at 25, 37, 50, and 60 °C. KOH-soluble and -insoluble fluoride formation on the enamel surface was then measured. KOH-soluble fluoride formation increased proportionally with temperature. KOH-soluble fluoride levels at 60 °C were 1.7-, 2.6-, and 2.7-fold greater than at 25 °C for 0.2% NaF, 2% NaF, and APF, respectively. Also, KOH-insoluble fluoride incorporation into the enamel increased pr...

Effectiveness of aspartate aminotransferase as a marker of periodontal disease in children and adolescents
Conclusions It was possible to measure AST levels in children and teenagers. It is suggested that we provide more specific information to children and their guardian using BANA and AST. Measuring biomarkers during regular oral check-ups could lead to an early diagnosis and intervention to avoid the progression of periodontitis during the childhood and teenage years.

Possible involvement of enolase in fluoride resistance in Streptococcus mutans
Publication date: April 2014 Source:Pediatric Dental Journal, Volume 24, Issue 1 Author(s): Chieko Mitsuhata , Mega Moeharyono Puteri , Yukari Ohara , Nobuyuki Tatsukawa , Katsuyuki Kozai Streptococcus mutans is the principal causative agent of dental caries, for which fluoride is often used for prevention. However, despite routine use of fluoride, children continue to have tooth decay. This may be because of the presence of fluoride-resistant S. mutans. It is known that the enzyme enolase is very sensitive to fluoride, which would decrease S. mutans growth. We investigated how the expression of functional enolase in dif...

Complete resorption of an impacted and inverted supernumerary tooth: Report of an unusual case
Publication date: August 2014 Source:Pediatric Dental Journal, Volume 24, Issue 2 Author(s): Makiko Takashi , Mizuho Motegi , Yuzo Takagi The presence of supernumerary teeth is a relatively frequent odontogenic disorder. Supernumerary teeth should be extracted immediately if any complications such as diastema and delayed eruption are present; early diagnosis is therefore crucial. A 6-year-old boy had an impacted and inverted supernumerary tooth in the anterior maxilla. Removal was recommended but was not performed, at the patient's request. The patient's condition was monitored using oral and radiographic examinations fo...

Occurrence of partial ankyloglossia with isolated oligodontia in permanent dentition: A case report
Publication date: August 2014 Source:Pediatric Dental Journal, Volume 24, Issue 2 Author(s): Saraswathi V. Naik , S. Ghousia , N.D. Shashikran , Satyajith Naik , K.K. Shashihushan Abstract Ankyloglossia or tongue-tie is a relatively benign condition that causes difficulties in normal functioning of the tongue due to an anatomic variation in the lingual frenum, leading to the formation of thick and short frenum. This can be corrected with simple surgical procedures. Oligodontia is the developmental absence of six teeth or more, excluding third molars. It can be isolated or non-syndromic and/or can be a part of a syndrome....
