“…Another factor that affects caries progression in deep and narrow fissures is the closeness of these fissures to the dentinoenamel junction (DEJ). The distance between the deepest part of the fissure and the DEJ affects the progression of caries (23). Consequently, fissure caries can easily initiate and involve dentin.…”

Aim: Pits and fissures are considered the areas in the posterior teeth that are most susceptible to decay. The aim of this in vitro study was to evaluate the prevalence of fissure types in relation to tooth type and localization. Methodology: A total of 100 extracted sound maxillary and mandibular molars and premolars were included in this study (25 teeth/group). The extracted teeth without any caries, cracks, fractures, anomalies, or restorations were classified according to tooth type and localization after disinfection. The teeth were sectioned in the buccolingual direction from the deepest part of the central fossa on the occlusal surface, and the fissure patterns were observed using a stereo microscope. The frequency distribution and percentages of the categorical data were obtained. Chi-square and exact tests were performed to compare the localization of the teeth and the prevalence of fissure types (p < 0.05). Results: The V-type fissure pattern (59%) was statistically significantly more common in both the premolar and molar teeth, followed by the I-type (18%) and U-type (14%) patterns (p = 0.000). The rarest fissure pattern was the IK type. No relationships were found between fissure pattern, the tooth subgroups, and localization (p = 0.390). Conclusion: Determining the types of fissure morphology is important for the prevention of caries on the occlusal surfaces of molars and premolars.

“…Je obtížné stanovit, zda laryngoskopie jsou významným etiologickým faktorem vzniku VVS, protože se obvykle provádí u dětí předčasně narozených s VNPH a ENPH, u nichž jsou v postnatálním období diagnostikována závažná onemocnění. Pravděpodobně lokální i systémové faktory působí společně, a proto je velmi problematické, či dokonce nemožné určit etiologický faktor, který by byl nejsilněji spojen s VVS [25].…”

“…There are many investigations reporting different protocols for cleaning P&F 2 and for sealant application [3][4][5] . In a study published in 2007, Cruvivnel et al 6 suggested that the depth of P&F is the most critical factor in terms of possible pulpal involvement. They showed that the permanent dentition, the deepest part of the P&F is frequently located near or in direct contact with the enamel-dentine junction.…”

The aim of this descriptive ex vivo study was to evaluate qualitatively the depth of pit and fissures (P&F) of the enamel in human mandibular third molars. Fifty (n=50) extracted human mandibular third molars were cleaned and disinfected. All tooth surfaces were coated with nail varnish except for a 1-mm margin around the periphery of the occlusal surface. The teeth were immersed for 48 hours at 37 °C in 1% methylene blue dye solution prepared in artificial saliva. After cleaning, the crowns were separated from the root at the cementoenamel junction and subsequently sectioned longitudinally in buccolingual direction at the location of the central fossa. All sections were examined using a stereoscopic microscope and photographed. The images were downloaded on a computer. The length of penetration of the P&F was recorded using the following scoring system: C1: P&F extended to half of the enamel thickness; C2: P&F extended beyond half of the enamel thickness without reaching the dentine-enamel junction; C3: P&F extended to the dentine-enamel junction. For pits, C1, C2 and C3 were observed in 35, 9 and 6 teeth, respectively, while for fissures, C1, C2 and C3 were observed in 15, 18 and 17 teeth, respectively. The P&F detected in the samples extended to the deepest portions of enamel, quite frequently reaching the enamel-dentine junction. Clinicians should recognize that even if pits and fissures are not clinically obvious, they penetrate deep into the enamel and frequently reach the dentine-enamel junction. Effective treatment is recommended to block access to P&F, thus preventing ingress of bacteria.
