Oral pathogens in children with respiratory disease
Discussion We noted that the bacterial load of specific bacteria in the palate increased with Hellman dental age. Furthermore, the increase in bacterial load in the oral cavity at stage IA, when teeth have not yet erupted, suggests the need for oral management. (Source: Pediatric Dental Journal)

Dental findings and management in a child with hypomelanosis of Ito
Publication date: Available online 7 November 2014 Source:Pediatric Dental Journal Author(s): Tomokazu Hasegawa , Yuki Akazawa , Takamasa Kitamura , Asuna Sugimoto , Kimiko Ueda , Tsutomu Iwamoto Hypomelanosis of Ito (HI) is a rare neuroectodermal disorder characterized by hypopigmented whorls of skin along the Blaschko lines. Mental retardation and intractable epilepsy are also commonly observed in HI. However, there are only a few published reports describing dental observations in HI patients. Here, we report the oral management and novel dental findings of a male HI patient aged 3 years and 10 months. The chi...

Evaluation of changes in the dentoalveolar morphology in children with asthma
This study is centered on 44 asthmatic children aged between 6–12 years from J.S.S Hospital, Mysore. Selected variables from model analysis of the casts of the asthmatic group were subjected to comparison with those of the non asthmatic group, which comprised of 44 non asthmatic children. Selected parameters were arch width, arch length and palatal depth. Differences in arch widths, arch lengths and palatal depths between asthmatics and non asthmatics, and between subjects under regular and irregular medication in the asthmatic groups were evaluated by independent sample's ‘t’ tests. The results obtained revealed tha...

Horizontal impaction of primary mandibular bilateral central incisors identified in 2-year-8-month-old girl
Publication date: April 2013 Source:Pediatric Dental Journal, Volume 23, Issue 1 Author(s): Rena Okawa , Shuhei Naka , Kazuyo Fujita , Suguru Sakashita , Ryota Nomura , Kazuhiko Nakano A girl aged 2 years and 8 months came to our clinic for consultation with regard to unerupted primary mandibular bilateral central incisors. An intraoral examination revealed that the teeth had not emerged into the oral cavity and showed a tooth crown morphology similar to that of the primary mandibular incisors, which appeared in the lingual submucosal area outside of the mandibular dental arch. Periapical radiographs demonstrated...

Long-term follow-up of delayed development of maxillary right second premolar with inversely positioned corresponding primary molar
Publication date: April 2013 Source:Pediatric Dental Journal, Volume 23, Issue 1 Author(s): Rena Okawa , Shuhei Naka , Ayuchi Kojima , Hidekazu Sasaki , Ryota Nomura , Kazuhiko Nakano Impaction is defined as a condition in which a tooth fails to erupt within a normal range of functional position. The condition is generally found in permanent teeth, while impaction of primary teeth is considered to be uncommon. We previously presented a rare case of delayed development of a maxillary right second premolar with an inversely positioned corresponding primary molar identified in a girl aged 10 years and 4 months. In t...

Single-visit revascularization treatment of an immature permanent tooth with apical periodontitis: A case report
Publication date: April 2013 Source:Pediatric Dental Journal, Volume 23, Issue 1 Author(s): Yuko Fujita , Kenshi Maki We herein describe successful revascularization treatment of an immature mandibular left second premolar with apical periodontitis in a 10-year-old patient. The tooth was treated using coronal root irrigation with 5% sodium hypochlorite (NaOCl) and 3% hydrogen peroxide without instrumentation and then packed using calcium hydroxide paste into the coronal canal in a single visit. X-ray photographic examination showed the start of apical closure 5 months after the revascularization procedure. Thickening...

Management of open apices in thirteen traumatized permanent incisors using mineral trioxide aggregate: Case series
Conclusion Regular examination of immature traumatized permanent teeth is critical for vitality and apexification. In this report, clinical and radiological findings confirm that partial pulpotomy with MTA is a reliable and effective treatment approach in apexogenesis of traumatized immature permanent incisors with pulp exposure.

Application of a tooth-surface coating material to teeth with discolored crowns
In this study, we used BeautiCoat™ (Shofu Inc., Kyoto, Japan), a tooth-surface coating material that contains high levels of controlled-release fluoride, that temporarily improves crown color. We evaluated the effect of the primer on tooth-surface characteristics in addition to the coating agent's shear bond strength, tooth-surface condition, and duration of attachment. Additionally, we surveyed patients' satisfaction with the color improvement. The results showed no adverse effects of the primer on the enamel surface. The coating material itself showed a high degree of shear bond strength. Based on observations of shedd...

Molecular genetic investigation of dental attrition in mice
Publication date: April 2013 Source:Pediatric Dental Journal, Volume 23, Issue 1 Author(s): Chiaki Tatsumi , Kei Okamoto Inbred C3H/HeJSlc (C3H) and C57BL/6JSlc (B6) strains of mice fed a powdered high-cholesterol diet for 240 days were reported previously to exhibit high and low susceptibility to dental attrition, respectively. Although a number of physical and physiological factors are known to be related to attrition, genetic factors have rarely been discussed. In the present study, F2 mice were used to investigate the loci of genes that may be involved in attrition. The F1 strain was acquired by cross-breeding th...

Analysis of the genetic association between face breadth and maxillary arch width using SMXA recombinant inbred mouse strains
Publication date: April 2013 Source:Pediatric Dental Journal, Volume 23, Issue 1 Author(s): Takehiko Shimizu , Nao Ogawa , Akiko Hiraki , Takahide Maeda We measured the face breadth and the maxillary arch width of a total of 230 mice from 21 SMXA recombinant inbred (RI) mouse strains and their parental strains SM/J and A/J, and investigated genetic factors associated with these parameters. The coefficient of variation between maxillary arch width and face breadth within the same strain was low, suggesting that this is strictly governed by genetic factors. Maxillary arch width and face breadth exhibited a continuous...

Repair processes of experimental root fractures in rat molars examined by histopathological techniques and 3D micro-CT imaging
Conclusions Root-fracture investigation requires a combination of histopathological observation and 3D-CT imaging. Intra-alveolar fractured root repair accompanied by tubular reparative dentin formation at the pulpal side, and the deposition of cementum at the periodontal side, may occur when the fracture line is too narrow for the formation of granulation tissue.
