Abstract Background: Acceptance of lasers as alternatives and accessory tools to traditional methods in dental medicine has created an explosion of interest. Er:YAG laser is recommended for enamel conditioning. There is no study evaluating the anxiety in children during fissure sealing procedures when using Er:YAG laser compared to the routine application technique. Aim: To evaluate the objective and subjective stress parameters in children during a preventive procedure when using Er:YAG laser for additional enamel conditioning before pit and fissure sealant application compared to the routine clinical application technique. Materials and methods: The study included sixty-four 6-12-year-old children, divided into two equal treatment groups. A standardized fissure sealant application was performed, as in the intervention group before acid etching, the occlusal surfaces of teeth were conditioned with Er:YAG laser (2940 nm). During the procedure, objective and subjective stress parameters were recorded. Results: Significantly lower degree of dental anxiety was found at the end of the dental visit of the study group (p<0.001). During the professional cleaning of the tooth surface, the mean heart rate was low (95.55±14.29 bpm) within the physiological normal range. The objective and subjective stress parameters show no significant differences between the two subgroups during sealing procedure (p>0.05). Conclusions: Application of Er:YAG laser during sealant application does not provoke anxiety and is well accepted by children in dental environment. Preventive procedures at the beginning of a dental visit decrease the initial levels of dental anxiety and contribute to an effective treatment process.

This study aimed to investigate dentists’ general experience, knowledge about diagnosis, and treatment of dental erosive wear in young adults. A questionnaire was sent to 1262 Norwegian public dental health-employed dentists. The response rate was 60%. Results indicated that most dentists recorded erosive wear, half of them used a specific scoring system, and half registered lesions at the tooth surface level. Lesions were reported most often on palatal surfaces of upper anterior teeth (79% of dentists), on occlusal surfaces of lower 1st molars (74%), and on upper 1st molars (32%). Half the dentists used clinical photographs for documentation and 60% made study models. While 40% reported more erosive lesions in males, 36% reported no gender differences. High intake of carbonated beverages and acidic juices were reported as the most common cause by 97% and 72% of the dentists, respectively. Only 21% of dentists recorded the patient’s dietary history, and 73% never measured saliva secretion. The majority (78%) of the dentists treated patients with erosive wear themselves. In general, the survey suggests that the dentists are relatively up to date regarding the clinical recording, diagnosis, and treatment of dental erosive wear. However, dietary and salivary analyses were not given priority, and early, preventive treatment was lacking.

Original Group

The aim of this study was to evaluate retention and efficacy of polyacid-modified composite resin used as fissure sealant (Variglass V.L.C.) after six years. Three-hundred and seventy permanent first molars were sealed. After six years, 42.0% of the original group was re-examined and the sealant was found to be totally present in 3.4%, partially present in 16.2% and absent in 70.4% of the previously sealed occlusal surfaces. During the 6 years period, 9.5% of the sealed surfaces became carious, 25.0% were filled and 65.5% remained sound. Although the retention rate of the material has been very low, it appears to have prevented dental caries in 2/3 of the teeth evaluated after six years of placement.

Objective: To compare the subsurface mineral loss preventing capability of resin infiltration technique with topical fluoride and fissure sealant applications to demineralized occlusal fissures under simulated oral conditions. Materials and Methods: Occlusal surfaces of 64 extracted intact human third molars were demineralized. Next, the teeth were classified into four groups according to preventive applications (n = 16): G1, Specimens used as the control group with no preventive treatment; G2, Topical fluoride application (APF Gel/ DEEPAK); G3, Fissure sealant application (ClinproTMSealant/ 3M ESPE); and G4, Resin infiltration technique (Icon/ DMG). Chemical compositions before pH cycling were evaluated for eight specimens from each group. The remaining eight teeth from each group were subjected to pH cycling for 15 days to simulate the oral conditions. Subsequently, the specimens were fractured after immersion in liquid nitrogen and the subsurface fluoride (F), calcium (Ca), phosphorus (P) levels, and Ca/P ratio of each specimen were measured using energy dispersive x-ray spectrometer (EDS). The data were subjected to statistical analysis (p = 0.05). The effects of preventive applications to surface topography of specimens were evaluated using scanning electron microscope (SEM). Results: There were no significant differences among the groups in subsurface F, Ca, and P levels and Ca/P ratios before or after pH cycling (p > 0.05). All three preventive applications were effective during pH cycling according to SEM observations. Conclusions: The subsurface mineral loss preventing capability of resin infiltration technique applied to occlusal fissures was comparable to topical fluoride and fissure sealant applications. Clinical significance: The resin infiltration technique could represent a valid alternative to traditionally used both preventive and restorative treatments for treating initial carious lesions on occlusal fissures, offering the advantages of better resin penetration and retention.

Aim. To reveal the additional value of radiographic bitewings (BW) in detection of caries and in comparing the occurrence of clinically undetected severe decay between 14-year olds with and without clinically observed dentinal caries in a low-caries prevalence population.Design. The cross-sectional study used 363 pairs of radiographs read by one examiner without knowledge of the clinical findings. The yield was analyzed on a tooth surface level by cross tabulating the clinical and radiographic information and on an individual level by counting the number of yield surfaces for all subjects. Mann-WhitneyUtest was used.Results. On a tooth surface level, the contribution of BW was the greatest on the occlusal surfaces of the first molars, where established or severe dentinal decay was registered in BW in 11% of clinically sound surfaces and in 40% of established cavitated enamel lesions. On an individual level, 53% of subjects benefited from BW. The subjects clinically DMFS > 0 benefited more than the clinically DMFS = 0 subjects (P=.004), nearly 60% in relation to 47%, respectively.Conclusions. In a low-caries prevalence population a remarkable portion of both clinically DMFS = 0 and DMFS > 0 14-year olds benefit from BW examination. Most of the benefit is obtained on the occlusal surfaces of the first and the second permanent molars.

Morphometric Assessment

A dentist needs special knowledge in odontology and odontoglyphics, which allows visualizing the space and relief of the tooth surface, as well as conducting an in-depth analysis of the individual morphometric characteristics of the tooth. Expansion of knowledge about the variability of the occlusal relief will allow achieving balanced occlusal-articulation relationships of the dentition and preserving the physiological state of the dentition. The article presents the results of odontoscopic and morphometric studies of vertical, transverse parameters of the upper large molars in patients with various physiological types of occlusion. The subject of the study was the segments of the upper molars obtained from plaster models of the jaws of 92 people with physiological occlusion, a full set of permanent teeth and various types of dental system (patients in group 1 – normodontism, patients in group 2 – macrodontism, patients in group 3 – microdontism). For morphometry in the transverse direction, the vestibular-lingual size of the crown and neck of the tooth, as well as the intertubercular distance, were used. To measure the vertical parameters, the height of the mesial (protocone, paracone) and distal (metacone, hypocone) odontomeres and tubercle of the occlusal surface was determined. The results of the study showed that in people with physiological occlusion and macrodontism of permanent teeth, vertical, transverse parameters exceed those of people with normodont and microdont types of the dental system. It is advisable to use the obtained odontometric features at the stages of diagnosing occlusal relationships and identifying various forms of pathological, physiological abrasion with varying degrees of loss of occlusal surfaces.
