“…(12,24,25) These differences can be attributed to the difference in the age profile of the participants. (26) The present study showed that the prevalence of DH in the mandibular premolars and canines is higher. Similar studies also have reported a higher prevalence of DH in premolars.…”

Background and Aim: Dentin hypersensitivity (DH) is one of the most common problems in dentistry. Several factors affect DH. This study aimed to determine the prevalence of this problem and identify the associated factors. Materials and Methods: : In this cross-sectional study, 300 patients who referred to the operative dentistry department of Islamic Azad University of Medical Sciences, Tehran, Iran, were examined. Demographic information and other related factors were recorded using a questionnaire. One examiner then examined the subjects regarding the potential related clinical factors. DH was evaluated using evaporative and tactile tests and was categorized using the visual analog scale (VAS). Descriptive data were presented as frequency and mean. Chi-Square test was used to examine the related factors at the significance level of 0.05. Result: The overall prevalence of DH was 21%. The correlation of horizontal brushing technique (P<0.005), hard toothbrushes (P<0.0001), gingival recession (P<0.0001), history of gingival surgery (P<0.001), tooth wear (P<0.001), traumatic occlusion (P<0.005), and bleaching toothpastes (P<0.005) with DH prevalence was significant. Conclusion: According to the results, high awareness about DH and its associated factors is mandatory.

“…All patients received thorough oral prophylaxis and oral hygiene guidelines 1 week before the clinical examination to prevent any signs of gingival inflammation. Location of Cemento‐enamel junction (CEJ) was done using a combination of conventional method (feeling the catch at the cervical region when the probe is moved from a smoother enamel to a rougher root surface) and radiographic method (demarcation between more radio‐dense enamel and less radio‐dense root cementum) . A point of 3 mm apical to previously located CEJ was marked on tooth #4, #5, #12, and #13, respectively, and this point is used as a reference for the measurement of attached gingival thickness and corresponding buccal bone thickness.…”

Objective To noninvasively determine the relationship between the thickness of the buccal bone and attached gingiva of the maxillary premolars. Material and Methods 128 maxillary premolars in 32 patients were assessed for measurement of buccal bone thickness and corresponding attached gingival thickness at 3 mm apical to cemento‐enamel junction. Buccal bone thickness was measured on cone‐beam computed tomography scans and attached gingival thickness by ultrasound unit. Pearson's correlation coefficient was calculated to assess the correlation between buccal bone and attached gingival thickness at each tooth type. Results The mean buccal bone thickness at the maxillary premolars was 1.07 mm. The 1st premolars had a buccal bone thickness < 1 mm at 68% of all sites, and the 2nd premolars had a buccal bone thickness of 1.0‐2.0 mm at 32% of all sites. The 1st premolars had a gingival thickness > 1.2 mm at 55% of all sites, and the 2nd premolars had a gingival thickness of 1.1‐1.3 mm at 45% of all sites. The correlation between buccal bone and attached gingival thickness was moderately positive (r = 0.406; P < .001). Conclusions The relationship between buccal bone thickness and gingival thickness is independent of each other in the maxillary right first premolar, whereas a moderate correlation with a dependent relation exists in the maxillary right second premolar, maxillary left first premolar, and maxillary left second premolar. Clinical Significance Soft tissue and hard tissue associated with volumetric changes in maxillary premolar region can be unfavorable for both aesthetic and implant placement. In fact this study highlighted the relationship between the thickness of attached gingiva and corresponding buccal bone in maxillary premolar region so to enable for proper planning of implant therapy following extraction.

“…The importance of CEJ in periodontics and restorative odontology is increasing with aging of an individual (11,12). The neck region of the tooth was mostly investigated for cervical and radicular caries, increased sensitivity of the teeth and the frequent occurrence of cervical erosion (13,14).…”

ACTA FACULTATIS MEDICAE NAISSENSIS UDC: 616.314 SU M M A RYCemento-enamel junction (CEJ) is an important anatomical structure of the tooth, which is located in the cervical part of the tooth between the crown and root, or at the contact point between the enamel which overlaps the tooth crown and cementum overlapping the root dentin.There are four possible relationships between two tissues that make the CEJ such as: the cement overlaps the enamel; the enamel overlaps the cement; the enamel and cement abut each other with no overlap; the enamel and cement are not in contact. The aim of this study was to determine the relationship between the enamel and cement which make the CEJ in different types of permanent teeth.The material consisted of 30 permanent teeth with intact CEJ. Staining of CEJ was carried out using the methylene blue. After staining, the tooth was washed under the running water and drying at room temperature. Each tooth was longitudinally cut in the vestibular-oral direction. Observation of CEJ was done with Leica light microscope and images were obtained using a Nikon camera.The results indicated that the most common form of CEJ between the cement and enamel in the region of CEJ was that cement and enamel abutted without overlap (36.7%), followed by the cement overlapping the enamel (33.3%), and the cases when a gap between the cement and enamel (16.7%) was present, and when the enamel overlaped the cement (13.3%).Because of the morphological diversity of CEJ, careful performing of dental interventions in the region of tooth neck is necessary because they may change the morphology of this region, induce the pathological processes and hypersensitivity of teeth.
