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 proportionally with the sol...

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 enolas...

Analysis of the calcification caused by rapid expansion of interpremaxillary suture in growing rats
Publication date: April 2014 Source:Pediatric Dental Journal, Volume 24, Issue 1 Author(s): Masanobu Kashitani , Takahiro Nishioka , Katsura Saeki , Ikuko Nishida , Kenshi Maki Changes in the bone mineral density and the speed of mineralization were evaluated when the interpremaxillary suture received a physiological or orthodontic force in rats' growth period. Wistar rats (N = 30), 6 weeks of age at the beginning of the experiment, were used for this study. A rapid expansion appliance was set on the maxillary incisors of the rats in the experimental groups (1.5 mm expansion and 2.0 mm expansion groups), while t...

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 examinatio...

Hypoplasia in crown of primary mandibular left lateral incisor identified in infant Japanese girl
Publication date: August 2014 Source:Pediatric Dental Journal, Volume 24, Issue 2 Author(s): Rena Okawa , Shuhei Naka , Kanae Saga , Ryota Nomura , Kazuhiko Nakano A girl aged 0 years 11 months was referred to our clinic by a local pediatrician for examination of a missing tooth crown of a primary mandibular left lateral incisor. Our intraoral examination showed that seven primary incisors had emerged into the oral cavity, while no tooth crown was noted in the region of the primary mandibular left lateral incisor. A calcified structure was identified close to the gingival margin, which had a bone-like appearance a...

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 sy...

Delayed eruption of mandibular primary central incisors in a child with severe lingual inclination and their spontaneous movement to appropriate positions
Publication date: August 2014 Source:Pediatric Dental Journal, Volume 24, Issue 2 Author(s): Rena Okawa , Shuhei Naka , Miharu Higashino , Ryota Nomura , Kazuhiko Nakano We previously reported a quite uncommon case of delayed eruption of primary mandibular bilateral incisors with severe lingual inclination identified in a Japanese girl aged 2 years 8 months. An intraoral examination demonstrated the tooth crown morphology of the primary mandibular incisors in the lingual submucosal area, while radiographic examinations of the affected teeth revealed what appeared to be a standard root morphology and the permanent ...
