Of these classifications, Class III and hyperdivergent are the least studied. This study aimed to investigate the prevalence and relationship between Class III and hyperdivergency. Materials and Methods: Lateral cephalometric radiographs of Class III patients were collected from Riyadh Elm University and were traced by WebCephTM software and measured for 16 linear and angular measurements to determine anteroposterior, vertical, and dental associations. To determine the anteroposterior relationships, Sella-Nasion to A point Angle, Sella-Nasion to B point Angle, A point to B point Angle, and Wits appraisal were used. Class III status was determined by utilizing (A point to B point Angle <1) and (Wits appraisal <−2.5). The vertical divergency pattern was considered according to normal Frankfort horizontal plane and mandibular plane (FMA) (22°–28°) and SN-GoMe: Sella-Nasion to Mandibular plane (27°–36°) measurements. The dental correlation was considered according to upper incisor to maxillary plane (U1-Mx) and lower incisor to mandibular plane angle. Statistical analysis was performed with SPSS (version 25) software. Results and Conclusions: One hundred and twenty-five Class III patients were included in the final analysis of this study. A significant correlation at 0.650 was discovered between ANB and Wits analyses (<0.001). Subjects data was grouped, based on their mandibular divergency, into hypodivergent, normodivergent, and hyperdivergent. The distribution, regardless of measurement used, was significantly higher in the prevalence of hyperdivergents (FMA 46.4% and SNGoMe 56%) over hypo- and normodivergents. Although FMA and SNGoMe were positively correlated at 0.887, there were significant differences in their classification of divergency with higher levels of hyperdivergency with SNGoMe.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"50 1","pages":"172 - 176"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74553018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim: The aim of the study was to compare the external apical root resorption (EARR) of endodontically treated teeth before and after orthodontic movements using clear aligner therapy. Materials and Methods: The study group comprised 22 class I adult healthy patients with a mean age of (28 ± 8.2) years treated with clear aligner therapy. Thirty-four endodontically treated teeth (maxillary incisors and molars) were measured for the extent of the EARR in panoramic radiographs at the beginning and at the end of clear aligner therapy. Root resorption was measured using an electrical digital caliper (Mitutoyo Manufacturing Co. Ltd., Tokyo, Japan) on the dental panoramic radiographs from the mesial cusps of the first molar tooth to the apex of the root, and from the incisal edge to the apex of the root for the central incisors. Results and Discussion: All the endodontically treated teeth demonstrated reduction in pretreatment root length. Less than one percent of EARR was found in 4 teeth, and 1%–4.9% of the EARR was observed in 23 teeth. Six teeth showed EARR of 5–7.9 while only one tooth EARR in the range of 8–10. A pretreatment versus posttreatment comparison of median root lengths of #16, #26, #36, and #46 showed a statistically significant difference (P < 0.05). The mean differences of root lengths after clear aligner therapy among different teeth showed no significant difference (P = 0.981). Conclusion: All the endodontically treated teeth showed minimal external root resorption after orthodontic treatment with a clear aligner.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"43 1","pages":"157 - 162"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86976338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dentinogenesis imperfecta (DI) is a disease characterized by an abnormal formation and abnormal structure of the dentin, generally affecting both primary and permanent dentition. The only epidemiological data available were published in 1975 by Witkop, who estimated the incidence of dentinogenesis imperfecta to be between 1/6000 and 1/8000. We present a case of DI III with an unusual presentation of rhizomegaly, dilacerations of the root, and taurodontism, seldom reported in the English literature for any genetic disorder of dentin. Clinical management is challenging in such cases, as the literature mentions that only an early diagnosis and early treatment with periodic follow-up can help improve the quality of life. Psychological and genetic counseling along with a multidisciplinary approach is mandatory for the cases such as the one presented here.

It is not known if the time is appropriate to totally shift from training students on conventional analog film-based radiology to training them on digital images and the choice of digital system in intraoral and extraoral radiography. Aim: The aim of this study is to assess availability and utilization of the digital radiographic techniques by dental clinics in Riyadh, Saudi Arabia, using a cross-sectional descriptive, epidemiological survey. Materials and Methods: The study included dental departments of nine main governmental hospitals, six dental schools in Riyadh and a representative selected sample of the private dental clinics in Riyadh that included 40 dental clinics. A self-administered e-survey regarding the use of analog or digital radiographic intraoral and extraoral techniques was made. Descriptive statistics are reported in forms of means and range. Results and Discussion: For intraoral radiographic examinations, most clinics (90.9%) used digital systems. Solid-state detectors such as charge-coupled device (CCD) and complementary metal oxide semiconductor sensors were the most popular type digital intraoral sensors (94%) and only 13 locations (26%) used digital photostimulable phosphors plates. For panoramic radiography, almost all (98.1%) used digital systems. Again, the solid-state detectors were the most common digital panoramic system (96.4%). Most respondents had a digital information system to store, retrieve, and display digital radiographs (92.7%), whereas only four locations (5.9%) used hard-copy films or paper prints. Conclusion: Digital imagining is more common than film-based imaging in intraoral radiography in and panoramic radiography in the different dental care delivery sites in Riyadh, Saudi Arabia.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"23 1","pages":"139 - 142"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88228817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aims: The aim of this study was to assess the impact of three methods of teaching: Online interactive virtual classes, recorded lectures, and real-life classroom lectures on the academic performance of dental students. The second aim was to evaluate the students' perceptions of the two remote teaching methods as a substitute for traditional classroom lectures. Materials and Methods: The cross-sectional study was conducted with the second-year dental students at the College of Dentistry, King Saud bin Abdulaziz University for Health Sciences, during the spring semester of 2020. The last six lectures of a Preclinical Fixed Prosthodontics course were delivered remotely due to the COVID-19 pandemic. The students' performance in these lectures was compared to their performance in the first nine lectures of the course delivered traditionally before the quarantine period. An online survey was distributed to the students at the end of the course with questions about their perceptions regarding the different teaching methods used to deliver the didactic component of the course. Results and Discussion: The performance of 104 students (56 males and 48 females) was assessed through the number of correct responses for each teaching method. The percentage of students who responded correctly to all the questions was 44% for the classroom lecture format, 75% in the interactive virtual class format, and 78% in the recorded lecture format. The response rate to the online survey was 87.5%. The majority of the students (78%) indicated that the interactive virtual classes were an effective learning method. The perception about viewing recorded material was also positive as 83% of the students agreed that it is an adequate learning method when the classroom lectures were canceled. Nevertheless, only 43% indicated that recorded material could be used as a substitute for classroom attendance. Conclusion: The students' performance in the lectures taught remotely in interactive virtual classes or by viewing recorded lectures was both effective and comparable to traditional classroom lectures. The dental students were generally satisfied with the remote online education.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"11 1","pages":"177 - 183"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80702166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An arsenal of different desensitizing molecules is available on the market, but no gold standard has yet to be set.Aim: The aim of this study was to perform a review on the potential of nano-hydroxyapatite (n-HA) as a desensitizing toothpaste agent as opposed to placebo or other desensitizing molecules. Materials and Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, an electronic search of the PubMed database was conducted from inception up until May 2021. Seven English written randomized controlled trials about the use of n-HA toothpaste in treating adults with DH were assessed for quality via the modified Jadad scale, and included in the review. Non-English studies, publications involving lasers, and studies researching the effect of n-HA on gingival inflammation or postwhitening sensitivity were all excluded. Results and Discussion: Available evidence suggests that n-HA is a promising addition to the growing arsenal of desensitizing treatments available on the market. Conclusion: n-HA remains a viable everyday option that dentists should strongly consider for their patients' pain relief. However, due to the heterogeneity of pain studies and the lack of standardization in trial protocols, no evidence of superiority to other desensitizing agents can be ascertained, thus far.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"98 1","pages":"122 - 128"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80549389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim: The purpose of this study was to evaluate the knowledge and perception of dental practitioners about PPE to limit the spread of coronavirus disease 2019 (COVID-19). Materials and Methods: This cross-sectional descriptive study was conducted between May and June 2020 among the dental practitioners working in public and private sectors of Saudi Arabia. An online questionnaire was distributed among dental practitioners across Saudi Arabia using E-mails or WhatsApp software. The questionnaire consisted of two parts: (1) basic demographic characteristics (gender, professional status, type of dental setup, and working experience) and (2) knowledge and attitude regarding the use of a face mask, gloves, gowns, and personal hygiene. Descriptive statistics were performed to summarize frequencies and percentages. Results and Discussion: The total number of the responses received was 535 (68.8% – male and 31.2% – female). Only 17.8% knew that surgical masks are made of nonwoven fabric and that the middle layer acts as a barrier (39.8%). Regarding gloves, 57.4% of the participants agreed that latex/nitrile gloves are more reliable and durable. On the contrary, satisfactory knowledge regarding face shield, gown, hand hygiene, and infection control measures was observed. Conclusions: This study showed a low level of certain PPE knowledge among dental practitioners.
