Clinical Characteristics and Differential Diagnosis of Hypomineralised Second Primary Molars and Molar Incisor Hypomineralisation.

Molar incisor hypomineralisation (MIH) and hypomineralised second primary molars (HSPMs) are commonly seen dental developmental problems with a mean prevalence of around 14% and 9%, respectively, but with a large variability in the reported prevalences. From the dental development, we know that the enamel mineralisation of the second primary molar is taking place between the 19th week of pregnancy until 1 year of age. For the first permanent molars (FPMs) and incisors, the enamel mineralisation is taking place between birth until the age of 3-5.

Radiographic dentinal caries and its progression in occlusal surfaces in Dutch 17-year-olds: a 6-year longitudinal study.

In this study, the status of 705 occlusal surfaces of first and second molars of 90 17-year-olds was analysed longitudinally in a 6-year follow-up, using a combination of clinical and radiographic information. Clinical data were derived from an epidemiological project. Each of two examiners judged all bitewing radiographs.

Clinical evaluation of visual, radiographic, and laser fluorescence methods for detection of occlusal caries.

The aim of this clinical study was to test cut-offs for occlusal caries detection by the laser fluorescence device DIAGNOdent (DD) in comparison to visual-ranked inspection (VI) and bitewing radiographs (BW) under condition of a general dental practice. 281 occlusal surfaces of permanent molars from 97 patients were examined with VI, DD and BW. Caries extent was verified by bioptical intervention (gold standard) of 248 molars.
