Most of the time non-vital teeth are associated with various pathologies. The early intervention would save the teeth from its loss. Depending on the etiology and the duration, the pathology differs among the non-vital teeth. The aim of this study was to evaluate non-vital teeth with various endodontic pathologies. This retrospective study included patients who were diagnosed with non-vital teeth from July 2019 to March 2020 in a dental hospital. The case records of all patients were retrieved which included the clinical , radiographic examination and treatment done for the patients. Variables such as age, gender, any associated endodontic pathologies were retrieved from the case sheets. Data was tabulated and was subjected to statistical package IBM SPSS version 20.0.Around 80,000 patients were reviewed and 238 patients met the inclusion criteria.Out of 238 patients, 71.8% were males and 28.2% were females.On analysing the prevalence of non vital teeth among different age groups, 21-30 years age group (32.8%) were more affected. On comparing the non vital teeth with endodontic pathology ,non-vital teeth without periapical lesion (74.4%) were found to be in a higher prevalence. Among non-vital teeth with endodontic pathology, periapical abscess (14.3%) was found to have higher prevalence followed by periapical cyst (2.9%) and calcified canal (2.9%).On analysing the prevalence of non vital teeth among gender , males (71.8%) were more affected. No statistically significant association was found between age, gender and non vital teeth. (p>0.05).Within the limitation of the study, the prevalence of non-vital teeth without periapical lesion were found to be higher. Among non-vital teeth with endodontic pathology, the most common pathology was chronic periapical abscess.Males were more affected with non vital teeth and had higher prevalence among the 21-30 years age group.

“…Assessment of dental color is one of the most critical components of cosmetic dentistry. [ 1 ] Darkening of a single anterior tooth produces a negative aesthetic effect due to the lack of coincidence in color with the rest of the teeth [ 2 , 3 , 4 ]. Such color alteration may occur after endodontic treatment and/or following trauma due to pulp hemorrhage and necrosis, or as a result of the use of certain endodontic sealing agents, drugs, or restorative materials [ 5 , 6 , 7 ].…”

“…Such color alteration may occur after endodontic treatment and/or following trauma due to pulp hemorrhage and necrosis, or as a result of the use of certain endodontic sealing agents, drugs, or restorative materials [ 5 , 6 , 7 ]. Non-vital teeth appear to be darker and more saturated and have an increased hue interval, compared to their vital counterparts [ 1 ].…”

Internal bleaching is a conservative, non-invasive, and simple treatment that is frequently performed in daily clinical practice. The present in vitro study analyzes the oxygen expansion of different bleaching agents resulting from the oxidation reaction when interacting with enamel and dentin. Enamel and dentin were crushed separately until obtaining a fine powder with particles of an approximate size between 0.06 and 0.2 mm. Each enamel and dentin sample were mixed with 37% carbamide peroxide (CP 37%), 30% hydrogen peroxide (HP 30%), sodium perborate (SP) combined with HP 30% (HP 30% + SP) and SP with distilled water (SP). A total of 280 1 mm diameter glass tubes were used with 70 for each bleaching agent (30 for powdered enamel evaluation, 30 for powdered dentin evaluation, and 10 controls). The bleaching agents were placed in the prepared tubes immediately after mixing the components. As expansion occurred, the oil inside the tube was displaced, through which the resulting expansion was evaluated and measured for 10 days. A significant expansion was observed that varied in magnitude according to the bleaching agent and the tooth structure used. Student’s t test and Welch’s ANOVA were used to analyze the data obtained. The highest mean expansion of both enamel and dentin was observed with 30% HP (66.6 mm for enamel, 94.5 mm for dentin) followed by HP 30% + SP (48.6 mm for enamel, 52.7 mm for dentin), CP 37% (38.4 mm for enamel, 52.6 mm for dentin) and finally SP with water (12.7 mm for enamel, 4.4 mm for dentin). It was observed that the expansion in the SP group with enamel was significantly lower than in the rest of the groups, while that registered for HP 30% was significantly higher. (p < 0.001). The results with dentin were similar, with a significantly lower expansion for SP and higher for HP 30% (p < 0.001). The oxygen expansion observed as a result of the interaction between bleaching agents and dental tissues could contribute to improving our understanding of bleaching and its results. These results suggest that bleaching agents react with the organic component of the tooth structure.

“…The main objective of this study was to compare measurements obtained by different instruments with the same optical geometry and to evaluate the proposed method of harmonizing color measurements for dental application using different dental materials with clinically relevant color range, translucency, and thickness. [18][19][20][21] According to the available literature, this is the first study that has evaluated measurement harmonization related to the dental industry.…”

This multicenter study evaluated the effect of harmonizing spectrophotometric (d/8) color measurements by using actual dental materials of clinically relevant thickness and translucency as "calibration tiles." Ten tooth-colored, 1-mm thick, resin-and ceramic-based materials were tested at the coordinating center (CC) and six research sites (RS). Correction factors were calculated for each material and each site to obtain the corrected reflection spectra from the non-corrected data set. Non-corrected (NC) and corrected (C) reflection values were converted into CIEDE2000 and CIELAB color parameters for the following comparisons: CC vs RS NC and CC vs RS C , between RS NC vs RS NC and RS C vs RS C pairs, and among RS separately (α = 0.05). Mean color differences for CC vs RS NC and corresponding CC vs RS C values were ΔE 00 = 4.2 (2.6) and ΔE 00 = 0.7 (0.6), respectively. Corresponding values for RS NC vs RS NC and RS C vs RS C specimen pairs were ΔE 00 = 5.9 (2.9) and ΔE 00 = 1.0 (0.5), respectively. The CIEDE2000 NC vs C comparison for each research site separately ranged from 0.5 to 8.5. Color differences of CC vs RS C and RS C vs RS C pairs decreased 83% to 84.5% as compared with respective color differences for non-corrected research site measurements and was RS dependent (P < .001). The obtained results validated the proposed method of harmonizing color measurements for dental application as a reliable quality control tool for dental research laboratories and industry.
