RESUMO

BACKGROUND An aged population is susceptible to chronic diseases, which impacts oral surgery treatment procedures. This retrospective study aimed to evaluate the incidence of medical comorbidities in 640 oral surgery patients treated at the College of Dentistry, Jazan University. MATERIAL AND METHODS This single-center observational study investigated medical records of outpatients who visited Jazan University Dental College Hospital in a 1-year period (2018-2019). Patients’ clinical and radiographic archives were screened to obtain relevant data. Categorical and continuous variables were expressed in terms of frequency and mean values, respectively. Differences in variables were statistically analyzed using the chi-square goodness of fit and proportional test, with a probability value P≤0.05 considered significant. RESULTS Analysis of 640 patient records included records of 300 men and 340 women who underwent oral surgery, of whom 176 patients (27.5%), including 97 men and 79 women, had medical comorbidities. The most common comorbidities were endocrine disease (7.03%), cardiovascular disease (6.71%), respiratory disease (4.53%), and hematological disorders (3.43%). Individual diseases that showed higher prevalence were diabetes mellitus (4.68%), hypertension (3.43%), bronchial asthma (2.65%), and anemia (1.4%). Differences by sex were observed in many individual disorders. CONCLUSIONS Outpatients in oral surgery clinics presented a significant variance in the incidence of medical comorbidities, among which diabetes and hypertension were most common. A proper case history is the best preventive measure that helps a surgeon avert medical emergencies and post-surgical complications.

RESUMO

BACKGROUND A luting agent is a dental cement used to secure a dental restoration. This study aimed to evaluate retentive strength of 50 endodontically-treated single-rooted mandibular second premolars (extracted) restored using 5 common luting (cement) agents. MATERIAL AND METHODS Fifty single-rooted mandibular second premolars with adequate root length and uniform size/shape were decoronated. After completing endodontic biomechanical preparation and obturation, root canals of all specimens were prepared to receive a cast post core. Depending upon cementation type, CPC specimens were divided in 5 groups (10 each) (Gp): Zinc phosphate (Gp ZP), polycarboxylate (Gp PC), glass ionomer (Gp GI), resin-modified glass ionomer (Gp RGI), and resin cement (Gp RC). Retentive strength was determined using the adhesive failure pull-out test. Mean/standard deviations were calculated for tensile forces (in kilograms) and differences were determined using analysis of variance (ANOVA). Multiple comparison was performed using the t test. A P value of ≤0.05 indicated a statistically significant difference. RESULTS The order of mean tensile strength from higher to lower was Gp RC (21.46) >Gp RGI (18.17) >Gp GI (16.07) >Gp ZP (15.33) >Gp PC (13.63). Differences in retentive strengths between the cements were significant (P≤0.05). Multiple-group comparisons showed that except for Gp ZP and Gp GI, all groups differed significantly from each other. CONCLUSIONS All investigated cements provided optimal retentive strengths, with wide differences between them. Resin cements should be used when CPC removal is not anticipated, while polycarboxylate or zinc phosphate should be used if CPC removal is anticipated.

RESUMO

BACKGROUND This study evaluated the effects of milling (CADCAM), 3D printing, preparation taper angles (10-degree and 20-degree), auxiliary retentive features (groove and box), and provisional cement types (conventional and resin-based) on the adhesive failure stress of 3-mm short provisional crowns (PC). The research was motivated by the need to understand how digital dentistry technologies impact the retention and durability of provisional crowns. MATERIAL AND METHODS A total of 160 working models (3D-printed) and PCs [80 milled (CopraTemp)/80 printed (Asiga)] were fabricated from two 10- and 20-degree typodont master models and two 20-degree 3D-printed master models (groove and box), simulating a 3 mm high all-ceramic short PC. After provisional cementation with conventional (Kerr TempBond) and resin-based (ProviTemp) cements, 16 subgroups (n=10 each) underwent thermocycling (10 000 cycles; 5-55°C) and pull-off tests on a universal testing machine. Statistical analysis was performed using one-way ANOVA and post hoc Tukey test. RESULTS Conventional cement failed at lower stress for milled (47.68 to 73.54) and printed (48.40 to 77.91) as compared to resin cement for milled (104.2 to 137.27) and printed (184.85 to 328.84), respectively, with significant differences. Increased taper and groove decreased failure load except for the printed PC/resin cement combination. Use of proximal box preparation increased retention significantly. Except for 20-degree taper cemented with conventional cement, the differences in auxiliary retentive features for milled and printed provisional crowns were statistically significant at P≤0.05. CONCLUSIONS 3D-printed PC, resin-based cement, 10-degree taper, and proximal box preparation were associated with higher retention than milled, conventional cements, 20-degree taper, and vertical groove.

RESUMO

OBJECTIVES: Sterilization eliminates microbial viability by decreasing the biological load, but likewise have the ability to deteriorate the mechanical properties of an implant material. This study intended to evaluate the effect of repeated moist heat sterilization on implant-abutment interface using two different implant systems. MATERIALS AND METHODS: Forty screw-retained titanium implant-abutment combinations (fixture 3.5 ×10 mm, abutment 2 mm diameter), twenty each from Genesis (Aktiv Implant Systems, United States) and Bredent (SKY, Germany), were divided into four different groups (n = 10) and placed in a computer-aided diagnostic model. The abutments from each group were exposed to first and second autoclave cycle (121°C for 30 minutes), connected back to the fixture and analyzed under scanning electron microscope for marginal gap and surface roughness. RESULTS: Genesis group showed higher marginal gaps on both sides (buccal/mesial [2.8 ± 0.47]; lingual/distal [2.8 ± 0.33]), while Bredent implant-abutment system (IAS) did not show any changes in marginal gaps after autoclaving. Differences within and between the group were found to be statistically significant. Surface roughness for Genesis (243.7 ± 70.30) and Bredent groups (528.9 ± 213.19) was highest at second autoclave, with Bredent implant-abutment showing higher values for surface roughness than Genesis IAS. CONCLUSION: Marginal vertical gap increased with autoclaving for Genesis IAS, while Bredent implant abutments were more stable. Surface roughness increases with autoclaving for both Genesis and Bredent group of IAS.

RESUMO

Maintaining a microbe-free environment in healthcare facilities has become increasingly crucial for minimizing virus transmission, especially in the wake of recent epidemics like COVID-19. To meet the urgent need for ongoing sterilization, autonomous ultraviolet disinfection (UV-D) robots have emerged as vital tools. These robots are gaining popularity due to their automated nature, cost advantages, and ability to instantly disinfect rooms and workspaces without relying on human labor. Integrating disinfection robots into medical facilities reduces infection risk, lowers conventional cleaning costs, and instills greater confidence in patient safety. However, UV-D robots should complement rather than replace routine manual cleaning. To optimize the functionality of UV-D robots in medical settings, additional hospital and device design modifications are necessary to address visibility challenges. Achieving seamless integration requires more technical advancements and clinical investigations across various institutions. This mini-review presents an overview of advanced applications that demand disinfection, highlighting their limitations and challenges. Despite their potential, little comprehensive research has been conducted on the sterilizing impact of disinfection robots in the dental industry. By serving as a starting point for future research, this review aims to bridge the gaps in knowledge and identify unresolved issues. Our objective is to provide an extensive guide to UV-D robots, encompassing design requirements, technological breakthroughs, and in-depth use in healthcare and dentistry facilities. Understanding the capabilities and limitations of UV-D robots will aid in harnessing their potential to revolutionize infection control practices in the medical and dental fields.

RESUMO

BACKGROUND The present study aimed to compare the clinical performance and gingival sulcus width changes in partially edentulous patients using cotton and polymer gingival retraction cords. MATERIAL AND METHODS Fifty partially edentulous patients were divided into 2 groups (Gp C and Gp P) and were subjected to single crown/fixed partial denture treatment. Clinical parameters, including plaque index scores, placement time, and hemorrhage control scores, were assessed. Gingival sulcus width changes before and after retraction were evaluated using individual type 4 dental stone dies observed under an optical microscope. Statistical analysis was performed using dependent/independent t tests. RESULTS The mean placement time, hemorrhage control time, and hemorrhagic scores were lower in Gp P than in Gp C, indicating better clinical performance of polymer-based retraction cord. Both groups showed an increase in sulcus width after retraction, but Gp P had a significantly higher sulcus width (690.03±45.37) compared to Gp C (471.38±28.13). The mean difference in sulcus width between baseline and after retraction was also significantly higher in Gp P (525.84 micrometers) than in Gp C (309.11 micrometers). CONCLUSIONS The present study shows that polymer-based cords produce more sulcus width and have better clinical performance compared to cotton-based gingival retraction cords. These results suggest that the use of polymer-based retraction cords can improve the quality of dental impressions in partially edentulous patients.

RESUMO

BACKGROUND Chlorhexidine (CHX) is not prescribed as a mouthwash for long-term use; therefore, probiotic/herbal mouthwashes are being investigated. This study compared the effect of 3 commercial mouthwashes on plaque index (PI), gingival index (GI), and bleeding index (BI) in patients with chronic gingivitis. MATERIAL AND METHODS Forty-five patients (all with moderate plaque) were randomly allocated into 3 groups (Gp): Gp 1 (CHX), Gp 2 (Manuka), and Gp 3 (Pro-Dental). Three periodontal clinical parameters - PI, GI, and BI - were recorded at baseline and on days 7, 14, and 28. An oral hygiene maintenance program was followed by a double-blinded intervention (coded bottle containing mouthwash). Both inter-group and intra-group comparisons were made using analysis of variance (ANOVA) with multiple t tests. All probable values were considered to have various levels of significance at P<0.05 or below. RESULTS All indices for all groups showed higher values (mean) at baseline, which were lower on days 7, 14, and 28. No differences in any clinical parameter at any point of time existed between Gp 1 and Gp 2. There were, however, significant differences (P<0.05) between Gp 1/Gp 3 and Gp 2/Gp 3 for all clinical parameters at all observed time periods (days 7, 14, 28). Intra-group comparison for all groups demonstrated highly significant differences between baseline values and other time points. CONCLUSIONS For managing chronic gingivitis, Manuka mouthwash is as effective as a CHX mouthwash, as there were no differences observed in any clinical parameters at any point points.

RESUMO

Human beings encountered malnutrition during the twentieth century and obesity in the very next century. This is how the future will look when the present becomes a slice of history. Obesity is threatening the healthy being of many youngsters throughout the world. Environmental influences have indicated to effect even genetically safe subjects among which parental neglect seems to be most alarming. Two extensively and globally investigated variables, the feeding style and the physical activity, provide some hope in its prevention. Despite the high rise of obesity prevalence in Saudi Arabia, there is scant research on these topics. The purpose of this review is to present a comprehensive assessment of these 2-obesity associated parental variables. The composed literature could provide an insight to the dominant surge of obesity in the Arab nations and stimulate research on current parenting practices in the Kingdom.

RESUMO

AIM: Post and core procedures are important clinical methods in routine dental practice. The present research aimed to radiographically assess the quality of post seating performed by undergraduate students at the College of Dentistry, Jazan University. MATERIALS AND METHODS: A total of 343 periapical X-rays of cemented posts (170 from males and 173 from females) were assessed. The assessment covered tooth type, arch, gender, type of post, length of post in relation to the crown and root lengths, the presence of any abnormality in post space, status of the remaining gutta-percha (GP), and the presence or absence of spaces between the end of post and GP. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) program (version 21), and associations between variables were determined using chi-squared or Fisher's exact tests. RESULTS: Maxillary teeth were the most frequently restored with posts, and the majority (41%) comprised incisors. Similarly, glass fiber post (69%) and taper-shaped posts (86%) were the most used posts. The majority of posts (81.6%) featured a width one-thirds that of the root. Lengths of posts were twice (58%) or equal to (51%) crown and root length respectively. More than 55% of cases presented 3 to 5 mm of GP at their apical portion, and 29% reached more than 5 mm. Approximately 5 to 8% of assessed cases revealed widening of periodontal ligaments, presence of periapical pathologies, and deviation of posts from the canal wall. Most cases (75%) showed the absence of space between GP and the post end. CONCLUSION: Qualities of assessed post and core restorations conducted by the 6th year dental students were clinically acceptable. CLINICAL SIGNIFICANCE: Periodic evaluation to determine the quality of delivered treatments is a vital cue for health service authorities. This evaluation will improve quality of services and treatments provided by dental students to their patients under the supervision of the faculty. Results obtained will also provide authorities with a clear feedback about academic infrastructure.

RESUMO

INTRODUCTION: Esthetic perceptions could differ between the dentist and his patients among various regions and cultures. AIM: The aims of this study were to evaluate the subjective differences between the dentist and the patient in terms of esthetics of metal-ceramic crowns (MCcs). The study also aims to compare the mesiodistal (MD) and buccolingual (BL) dimensions of the cemented crown with its respective natural antimeric tooth. MATERIALS AND METHODS: A total of 85 patients seeking treatment for a single crown (MC) were treated by the undergraduate students under supervision of respective academic staff. After cementation of the crowns, a 9-point questionnaire was given to patient and different dentists. A treatment cast for every single crown was poured. Then, the MD and BL dimensions of the crowns were compared against their respective antimeric tooth. RESULTS: The dentists and the patients agreed in the range of 50.5 to 90.5%. Least subjective differences were found for the length and width of the cemented crowns. The highest differences were noted for symmetry between the cemented crown and its antimeric natural tooth. A total of 31 to 38% of the patients differed from the dentist's evaluation for shade of the crown, color of the crown at the margin, contour of the crown, and the relationship of the crowns with the surrounding gingiva. The highest MD and BL dimensions were in the cemented crown of canines, while the lowest MD and BL diameters were for the cemented crowns of the lateral incisor crowns. CONCLUSION: Dentist and patient mostly agreed in terms of length (90%), width (81%) and relation of crown with free gingiva (74%). However, they differed mostly on the symmetry of the cemented crowns. The highest MD dimensions and BL diameter were in the cemented MCcs of canine, while the lowest were with lateral incisors. CLINICAL SIGNIFICANCE: While fabricating a dental prosthesis, the dentist must know about patients' perception of esthetics; otherwise both clinical and laboratory efforts would not be enough to satisfy the esthetic needs of the patient even if the restoration is technically correct. Perceptions related to symmetry differ mostly between dentist and patient.

RESUMO

INTRODUCTION: The aim of this study was to assess the prevalence and severity of temporomandibular joint disorders (TMDs) among undergraduate medical students in the presence of khat chewing over a period of time. MATERIALS AND METHODS: Totally, 186 medical college students (age < 20 years) were randomly selected for the present study. The study subjects were divided into two groups according to age, under 20 and above 20 years. The study was based on Fonseca's anamnestic index and its questionnaire, which is composed of 10 questions and classifies the severity of TMDs. The obtained data were coded and entered into Statistical Package for the Social Sciences (SPSS) program for analysis using chi-square test at significance level of 5%. RESULTS: Most of the participants were male (68.8%) students and older than 20 years (63%). Those who reported with khat chewing comprised 31.7%. From the total samples, only 38.0% was classified as having mild TMD and 0.50% were classified as having severe TMD. Poor dental articulation, grinding of teeth, headaches, tense personalities, and temporomandibular joint (TMJ) clicking were the most common clinical findings. The mean scores showed no significant difference among gender (p < 0.29) and the khat chewing (p < 0.531) groups for the 10 questions. However, it showed significant difference among age groups (p < 0.025). CONCLUSION: The majority of subjects complained of mild TMD, while only a few cases showed a moderate TMD among different age groups. The most frequently reported dysfunctions were related to poor dental articulation and grinding of the teeth, frequent headaches, the clicking of joint, and tense personalities. No significant difference was found between gender and khat and nonkhat chewing groups. CLINICAL SIGNIFICANCE: Khat chewing is a parafunctional habit and affects dental occlusion (especially cuspal wear) in terms of anterior guidance. Such alterations in occlusion are known to be one of the causative (predisposing) factors of TMD.

RESUMO

CONTEXT: This study is a continuation of the earlier studies and has been extended to investigate the potential forensic markers of elder abuse. AIMS: To determine the prevalence of elder abuse in various outpatient departments (OPDs). To study the associated parameters related to the abuser and the abused. To determine the existence of potential forensic markers of elder abuse. SETTINGS AND DESIGN: The subjects were randomly selected from the medical and the dental OPDs of the university. MATERIALS AND METHODS: Eight hundred and thirty two elderly subjects in the age range 40-60 years were interviewed using a questionnaire to determine the existence of elder abuse. The subjects were investigated and examined for weight, nutrition and hydration, vital signs, habits, existing visual and auditory capabilities, medications, disclosure of wills/deeds, signs of depression, and documented cleanliness. The mini-mental state examination, the Geriatric Depression Scale, the Clock drawing test, and the Brief Psychiatric Rating Scale were used to determine the potential forensic markers. STATISTICAL ANALYSIS USED: Mean values in percentage were determined by dividing the number of determined subjects by the total number of subjects for that parameter. RESULTS: About 37% in medical and 41% in dental OPDs were found to have suffered from abuse, mostly in the age group 60-70 years. Females received more abuse and a combination of son and daughter-in-law constituted most abusers. Various potential markers of elder abuse and neglect investigated among the elder abuse victims included depression (89%), signs of improper feeding (83%), changes in personal hygiene (69%), need for medical/dental treatment (78%), medication misuse (67%), changes in wills/deeds (26%), decubiti (10%), bruises (17%), skin tears (27%), and confusion (23%). CONCLUSIONS: Elder abuse exists in one or more forms in both medical and dental OPDs among both males and females in all age groups.
