Tooth fairy in training
\"Tate's tooth-fairy training starts today, and her big sister, May, is taking her out on her very first tooth-collecting mission. After practicing at home, Tate is ready to test her skills, and May leads her to their first stop: a herd of hippos in a lake! After all, human children aren't the only young creatures that lose their teeth. In fact, being a tooth fairy is a dangerous job, and Tate must visit all kinds of toothy predators before the night is up. Will she be able to collect the teeth from narwhals, anacondas, and more--all without waking a single creature?\"-- Provided by publisher.

Comparative efficacy of In-office and walking bleach techniques in whitening of non-vital teeth
Objectives
This study aimed to compare the efficacy of two non vital whitening techniques, In-office and Walking Bleach, using 35% hydrogen peroxide. The primary research question was to determine which technique achieves greater tooth color improvement.
Materials and methods
Fifty non-vital anterior teeth with discoloration were randomly assigned to either the In-office (
n
= 25) or Walking Bleach (
n
= 25) groups. Tooth color was measured using a Vita EasyShade V
®
spectrophotometer and visual scales (Vita Classical and Bleachguide) before treatment, after each bleaching session, and at a one-month follow-up. ΔE00, Whiteness Index (WID), and Shade Guide Unit (ΔSGU) values were calculated. Statistical analysis was performed using the Kruskal-Wallis and Mann-Whitney tests.
Results
Both techniques improved tooth color, with final ΔE00 values of 10.08 for In-office and 8.12 for Walking Bleach. WID values were significantly higher in the In-office group, indicating greater whitening efficacy. Significant differences favoring the In-office method were seen after the first bleaching (
p
= 0.0337), and one-month follow-up (
p
= 0.0327).
Conclusions
Both the In-office and Walking Bleach techniques effectively improve the color of non-vital teeth, with the In-office method showing slight advantages at certain times. Clinicians can choose either technique based on safety, patient needs, and clinical context to achieve optimal results.
Clinical relevance
This study provides evidence that both bleaching techniques are viable options for non-vital teeth whitening. The findings help clinicians choose the most appropriate technique based on biological safety and patient needs and desired outcomes, with the In-office technique being preferable for faster results.

Microdont Developing Outside the Alveolar Process and Within Oral Diffuse and Plexiform Neurofibroma in Neurofibromatosis Type 1
Numerical aberrations of permanent dentition and dystopic tooth eruption are part of the phenotype of the tumor predisposition syndrome neurofibromatosis type 1 (NF1). In these cases, surplus tooth germs usually develop in the alveolar processes of the jaw. This report attests to the dystopic development of a dysplastic supernumerary tooth in NF1 arising outside the jaw.
The 8-year-old male patient developed a microdont outside the bone and above the occlusal plane of the retained maxillary right second molar. The supernumerary tooth was completely embedded in oral soft tissue. Hyperplastic oral soft tissue in the molar region and microdont were excised. Specimen of the mucosa surrounding the teeth was interspersed with diffuse and plexiform neurofibroma. The retained upper right first molar emerged spontaneously within a few months after surgery. The upper right second molar did not change position.
Odontogenesis can take place within tumorous oral mucosa in NF1. Surgical removal of the tumorous mucous membrane facilitates tooth eruption in some cases.

Epidemiology, aetiology and prevention of tooth wear
Tooth wear is a commonly reported finding globally; however, many patients are unaware of having tooth wear. Identifying early signs of erosion, abrasion or attrition and determining the risk factors contributing to a patient's tooth wear may help to prevent further loss of enamel and dentine in the future. Appropriate prevention should be instigated, or appropriate referral made to other health professionals, when conditions such as gastroesophageal reflux or eating disorders are suspected. This paper presents the epidemiology and aetiological factors for tooth wear, as well as identifying the common clinical presentations of tooth wear. Patient perspectives on tooth wear and preventive techniques that can be utilised are also discussed.Key pointsThis paper summarises the clinical presentation of erosion, attrition and abrasion.Prevalence of tooth wear and aetiological factors are discussed in detail.Strategies for prevention of tooth wear are described.

Surface-Specific Efficacy of Fluoride Varnish in Caries Prevention in the Primary Dentition: Results of a Community Randomized Clinical Trial
Objectives: Fluoride varnish (FV) is efficacious in caries prevention although its effects among different tooth surfaces are poorly understood. This study sought to determine the extent to which caries-preventive effects of a community intervention that included FV application among preschool-aged children varied according to primary tooth anatomy and baseline tooth pathology. Methods: Secondary analysis was undertaken of data from a community-randomized controlled trial among 543 3- to 5-year-old Aboriginal children in 30 Northern Territory Australian communities. Children in intervention communities received community health promotion and FV application once every 6 months. Net caries (d 3 mfs) risk and 95% confidence limits (CL) were estimated for the control and intervention arms, and stratified according to tooth anatomy/location and baseline pathology (sound, enamel opacity, hypoplastic defect or precavitated carious lesion). The intervention’s efficacy was quantified using generalized estimating equation modeling accounting for study design and clustering. The assumption of efficacy homogeneity was tested using a Wald χ 2 test with a p < 0.2 criterion and post hoc pairwise comparisons. Results: The intervention resulted in a 25% reduction (relative risk, RR = 0.75; 95% CL = 0.71, 0.80) in the 2-year surface-level caries risk. There was substantial heterogeneity in FV efficacy by baseline surface pathology: RRs were 0.73 for sound, 0.77 for opaque, 0.90 for precavitated, and 0.92 for hypoplastic surfaces. Among sound surfaces, maxillary anterior facials received significantly more benefit (RR = 0.62) compared to pits and fissures (RR = 0.78). Conclusion: The intervention had greatest efficacy on surfaces that were sound at baseline. Among those sound surfaces, maxillary anterior facials received most caries-preventive benefit.

Effect of low-level laser therapy on tooth sensitivity induced by in-office bleaching
This study aimed to investigate the effect of low-level laser therapy (LLLT) on tooth sensitivity induced by in-office bleaching. Sixty-six patients enrolled in this randomized clinical trial. Following the in-office procedure with 40 % hydrogen peroxide, the participants were randomly divided into three groups. The patients in group 1 received irradiation from a low-level red laser (LLRL; 660 nm, 200 mW, 15 s, 12 J/cm
2
), whereas participants in group 2 were subjected to a low-level infrared laser (LLIL; 810 nm) under similar conditions as in group 1. In group 3 (placebo), the laser treatment was the same as that in groups 1 and 2, but without energy output. The degree of tooth sensitivity was recorded at 1, 24, and 48 h after bleaching using a visual analog scale (VAS). The change in tooth shade was measured 30 days after tooth whitening. The intensity of tooth sensitivity was not significantly different between groups at 1 h after bleaching (
p
> 0.05). At 24 h after therapy, pain level was significantly lower in the LLIL group compared to the LLRL and placebo groups (
p
< 0.05). At 48 h after bleaching, VAS scores in the LLIL and LLRL groups were comparable to each other (
p
> 0.05) and both were significantly lower than that of the placebo group (
p
< 0.05). There was no significant difference in the efficacy of tooth whitening among groups (
p
> 0.05). LLLT with an infrared diode laser could be recommended as a suitable strategy to reduce the intensity of tooth sensitivity after in-office bleaching.
