Comparative Evaluation of Dentinal Crack After Root Canal Preparation Using TruNatomy, Neoendo Flex, and Neoendo Neohybrid Files: An In Vitro Study.

AIM: The objective of the study was to assess and compare the dentinal microcracks produced by TruNatomy, Neoendo Flex, and Neoendo Neohybrid files during root canal preparation. MATERIAL AND METHODS: In this in vitro investigation, four groups of 25 samples each were assembled from 100 mandibular premolar teeth. Using TruNatomy, Neoendo Flex, and Neoendo Neohybrid files, or leaving the teeth unprepared (control), the teeth underwent root canal preparation. Horizontal sections were taken at different distances from the apex to analyze dentinal cracks. A stereomicroscope was used to assess the existence or lack of cracks, and chi-square tests were performed on the data. RESULTS: In the control group, there were no cracks. TruNatomy files created fewer cracks compared to Neoendo Flex and Neoendo Neohybrid files. CONCLUSIONS: This in vitro investigation demonstrates that the root surface might acquire dentinal cracks as a result of nickel-titanium instruments. Compared to Neoendo Flex and Neoendo Neohybrid files, TruNatomy showed a decreased incidence of cracks. However, it is important to note that these conclusions are limited to the scope of this study.

Comparative Evaluation of Primary Stability of Two Different Types of Orthodontic Mini-Implants.

BACKGROUND: The mini-implants introduced new possibilities of adequate anchorage in orthodontics. Furthermore, due to its small size, it can even be placed at relatively difficult sites with ease. Removal torque should be high to prevent implant unscrewing. OBJECTIVE: This prospective clinical trial was aimed to evaluate the insertion torque and removal torque of single-threaded and double-threaded cylindrical orthodontic mini-implants. MATERIALS AND METHODS: A total of 36 cases were randomly divided into two groups, with an equal number of patients in each group (n = 18). In Group 1 single-threaded cylindrical mini-implant was placed, and in the other group, cylindrical implants with double-threaded were placed. Maximum insertion torque (MIT) and maximum removal torques (MRTs) were recorded for both groups. Data collected were subjected to statistical analysis. RESULTS: MIT was found to be significantly higher than MRT for both the groups and between the groups. Intergroup comparison in the present study showed significantly higher values for MIT than MRT. Intergroup comparison of MIT showed more values for Group 2 as compared to Group 1. Similar statistically significant values were seen in terms with MRT, where double-threaded cylindrical mini-implants had more torque value than the other group. CONCLUSIONS: Orthodontic mini screws represent effective temporary anchorage devices. Double-threaded cylindrical mini-implants have significantly higher insertion and removal torque than single-threaded mini-implants and hence better stability.

Comparative Evaluation of Marginal Bone Loss and Implant Failure Rate in Smokers and Nonsmokers.

BACKGROUND: Smoking impose various ill-effects on the alveolar bone concerning dental implants including reduced bone height, delayed healing of bone, poor peri-implant bone formation, increased bone loss, and peri-implantitis. AIMS: The present clinical trial was aimed to analyze the smoking effect on dental implant survival rate as well as marginal bone loss in dental implants. MATERIALS AND METHODS: Out of 86 patients, Group I had 43 patients who were smokers and Group II had nonsmokers. Following the implant placement, marginal bone loss radiographically and mobility were assessed clinically at 3, 6, and 12 months after implant loading. RESULTS: The mean marginal loss seen in smokers at 3 months was 2.13 ± 0.21, 2.46 ± 0.09, 2.60 ± 0.0.92, and 2.74 ± 0.11 for maxillary anterior, maxillary posterior, mandibular anterior, and mandibular posterior regions, respectively. The 12-month recall visit showed a higher proportion of smokers having implant mobility. In smokers, 13.95% (n = 6) of the study participants had implant mobility, whereas 6.97% (n = 3) of the nonsmokers had mobility. CONCLUSION: Smoking is associated with long-term implant failure which is directly proportional to the duration ad frequency of smoking. Furthermore, smoking has a detrimental effect on dental implants and its surrounding bone.

Preservation of Alveolar Ridge using Graft Material after Tooth Extraction: A Clinical Trial.

BACKGROUND: The alveolar process is a tooth-dependent structure, and hence, removal of teeth results in the alteration of alveolar process. To alter bone remodeling after dental extraction, various techniques have been put forward for ridge preservation. AIM: The aim of this study is to evaluate and compare the changes of hard and soft tissues in postextraction socket after the application of bone graft material. MATERIALS AND METHODS: Healthy patients of sample size of 40 were selected who underwent the extraction of anterior tooth irrespective of the arch, from premolar of one side to another, with the exception of incisors in mandible. Twenty patients were randomly selected as the control group and other 20 as the experimental group using an allograft bone material, i.e., beta-tricalcium phosphate to fill the socket. Cone-beam computed tomography (CBCT) was done as baseline preoperative and postoperative at 14 weeks after the extraction. CBCTs data help in recording linear and volumetric measurements which was performed by calibrated examiners to record all the measurements. After measurements, digital planning of dental implants was performed. RESULTS: Forty participants were selected, in which 20 patients each were as the experimental and control groups. No significant difference was found at basal line at any of the cases. At follow-up of 14 weeks, statistical significance was seen in buccal and lingual plate height in the experimental group, and no significant difference was seen in the control group.(P = 0.023). CONCLUSIONS: This study clearly points out that an alveolar ridge preservation technique provides therapeutic benefit by limiting bone resorption in comparison to extraction alone.

Bone Graft and Intraosseous Anchorage of Dental Implants for Reconstruction of the Residual Alveolar Ridge.

BACKGROUND: Bone grafting aims at better dental implant osseointegration and preserves the remaining alveolar bone in the socket. The success of various bone grafting materials plays a vital role in assessing future implant function. AIMS AND OBJECTIVES: The present clinical trial was aimed at evaluating the results of guided bone regeneration (GBR) with and without the bioresorbable membrane in the dental implant placement. MATERIALS AND METHODS: The 20 patients were divided into two groups (n = 10). First was Group I- GBR with bioresorbable collagen membrane (BioGide™) and second was Group II- GBR without membrane. Bone gain and bone levels were analyzed for both groups. All the collected data were analyzed statistically. RESULTS: For Group I, bone levels at baseline were nonsignificant (P = 0.2188) Similarly, nonsignificant values were seen in both groups at 3 months with bone level values of 0.25 ± 0.17 and 0.38 ± 0.24 for Group I and Group II, respectively. Changes in the bone levels were found to be 2.45 ± 0.349 and 2.58 ± 0.304 from Group I and II, respectively, inferring the nonsignificant difference with P value of 0.3723. The percentage of bone gain for intergroup at the end of 3 months was 89.15% ±0.678 for Group I and 88.68% ± 0.503%; these values were statistically nonsignificant (P = 0.982). CONCLUSION: Nonsignificant difference was observed between the two groups with and without membrane in terms of changes in bone level, percentage of bone gain, and bone defect reduction. This study concludes that the use of bone grafts significantly improves residual alveolar ridge irrespective of membrane used.

Traumatic Ulcerations Frequencies and Postinsertion Adjustment Appointments in Complete Denture Patients.

BACKGROUND AND AIM: The patient who is wearing a denture after missing teeth faces traumatic ulceration very frequently. This ulceration creates difficulties in denture wearing. Hence, this study aimed to evaluate the most common locations of traumatic injuries in form of ulcerations, their frequency, and also the duration and number of adjustment visits required to achieve patient comfort following placement of complete removable dentures. MATERIALS AND METHODS: Eighty edentulous patients were selected from a private clinic. Complete removable dentures were fabricated for all patients. All patients were evaluated for their complaints after denture insertion. Patients were followed up till the problem persisted. Descriptive analysis was done. Chi-squared test was used to differentiate the associations between lesions, postinsertion visits, and gender. RESULTS: About 85.62% of patients need denture adjustment because of mucosal injuries during their first visit following. Approximately four appointments are needed for maxillary and six appointments needed for mandibular denture. Male and female have no difference in the number of mucosal injuries in the anatomical area evaluated in the maxilla and mandible using Fisher's exact test (P > 0.05). Mandibular dentures need more appointments than maxillary dentures after post insertion (P < 0.001). CONCLUSION: The vestibule was the most common site for mucosal injuries which can be corrected by proper extension of denture flanges during border molding. Pressure indicator ink (arti spot) and paste is used to correct the overextended denture flanges.

Mothers' sense of coherence and oral health-related quality of life in cleft lip and palate children visiting a private dental college: A Survey.

BACKGROUND: In addition to an adjusting physical appearance, children with cleft lip and palate also deal with psychological and psychosocial limitation. Mothers' sense of coherence (SOC) could be a psychosocial determinant of oral health quality of life (OH-QoL) of cleft lip and palate patients. Hence, the present study was done to assess the relationship of mothers' SOC on OH-QoL in cleft lip and palate patients. MATERIALS AND METHODS: The present cross-sectional questionnaire study was conducted on mothers of cleft lip and palate children. The first part consisted of demographic details. The second part of scale was the early childhood and oral health impact scale (ECOHIS) which had a total 13 questions with responses on a 4-point Likert scale. The third part was to assess mothers' SOC using a short version of SOC-13 consists of 13 items on a 7-point Likert scale. Chi-square test was applied to assess the association between mothers' SOC, sociodemographic characteristic, and children's OHRQoL. In the analysis, P < 0.05 was considered significant. RESULTS: Out of 69% of low SOC population, 21.73% were rural, 20.39% were from peri-urban, and 57.97% population was from urban areas. Out of 150 participants, 2.40% in high ECOHIS were illiterate/primary school, "31.32% were high school/intermediate/diploma had high ECOHIS while 66.26% were high school/intermediate/diploma" had low ECOHIS, and 25.37% were graduate/postgraduate. Mothers' education and locality were statistically significant P < 0.001. CONCLUSION: Action to enhance mothers' SOC might form part of oral health promotion and help to improve the oral health quality of life of cleft lip and palate patients.
