Pressure pain thresholds (PPTs) have been shown to be useful measures of mechanical pain sensitivity in deep tissues. However, clinical methods for measuring mechanical allodynia or hyperalgesia in teeth have not been reported. The aim of this study was to assess the reliability of PPTs in periodontal ligament of healthy Chinese participants. Twenty healthy young adults participated. Pressure pain thresholds were measured at six teeth and in two directions. The tests included three consecutive trials, in two separate sessions, which were performed on the first day by one examiner. After 1–3 wk, an identical protocol was carried out by two examiners, also in two separate sessions. There were no significant differences between repeated measures for all teeth. The PPTs had excellent reliabi…

Fluoride rinse effect on retention of CaF2 formed on enamel/dentine by fluoride application
Abstract Calcium fluoride-like materials (“CaF2”) formed on dental surfaces after professional fluoride application are unstable in the oral environment but can be retained longer with a daily NaF mouthrinse. We tested the effect of twice daily 0.05% NaF rinses on the retention of “CaF2” formed on enamel and dentine after applying acidulated phosphate fluoride (APF). “CaF2” formed on enamel/dentine by APF application significantly decreased after exposure to artificial saliva and the 0.05% NaF rinse was ineffective to avoid this reduction. These findings suggest that the combination of APF and 0.05% NaF is not clinically relevant, either for caries or dental hypersensitivity. (Source: Brazilian Oral Research)

Dental Lab Works To Provide Just The Right Fit
You wouldn’t think dentistry would be vulnerable to the economic pressures that have led large companies to move office work, call centers or manufacturing to cheaper states and countries. But these days nearly 70 percent of crown, dental implant and bridgework is done at dental labs outside Connecticut, according to Brian Fox, owner of Fox Dental, a lab in Glastonbury that’s 35 years old.

Cigarette smoking alters the mouth microbiota
The composition of mouth bacteria changes when people smoke, but it appears to return to its previous state after quitting. Bacteria that cause tooth decay increase, for example.

Breastfeeding, bottle feeding and risk of malocclusion in mixed and permanent dentitions: a systematic review
Abstract The aim of the present study was to search for scientific evidence concerning the association between breastfeeding and bottle feeding and risk of malocclusion in mixed and permanent dentitions. An electronic search was performed in eight databases up to February 2015. Additionally, a gray literature search and hand searches of the reference lists of the selected studies were also carried out. There were no restrictions on language or on year of publication. The methodology of the included articles was evaluated using the Newcastle Ottawa scale. Out of the 817 identified citations, six studies fulfilled the eligibility criteria and were included in the systematic review. One study showed that children with mixed and permanent dentitions breastfed for more than 6 months presented g…

Effect of filling technique on the bond strength of methacrylate and silorane-based composite restorations
Abstract The bond strength of methacrylate (Z350, 3M ESPE) and silorane (P90, 3M ESPE) restorations, using different cavity filling techniques, was investigated. Cavities (6 × 3 × 3) in bovine teeth were filled using bulk, oblique, or horizontal increments. A push-out test was carried out after 24 h. Data were statistically analyzed (? = 5%). Methacrylate-based composites and the horizontal filling technique showed the highest bond strength values (10.2 ± 3.9, p < 0.05). Silorane-based composites showed no statistically significant differences regarding the filling techniques (p > 0.05). (Source: Brazilian Oral Research)
