Multiple dentigerous cysts in a patient showing features of Gorlin-Goltz syndrome: A case report.

INTRODUCTION AND IMPORTANCE: The association between Dentigerous cysts (DCs) and Gorlin-Goltz syndrome (GGS) was claimed theoretically in a very few reports, with very few clinical foundations. The aim of this report was to present a unique case of multiple DCs in the mandible in a patient showing features of GGS. CASE PRESENTATION: A 63-year-old male patient presented with multiple cyst-like lesions in the mandible associated with some clinical and radiological features of GGS, and that raised the suspension of odontogenic keratocyst (OKC). The patient underwent marsupialization and enucleation of these cysts, and the histopathological examination confirmed the diagnosis of DCs. CLINICAL DISCUSSION: In this report, the patient presented with symptoms related to multiple unilocular radiolucent lesions found in the mandible and the clinical and radiological features were highly suggestive of OKCs associated with GGS. However, the perioperative findings raised the suspicion of DCs, which was confirmed by histopathology. Interestingly, GGS is an inherited autosomal dominant disorder arising from mutations in the patched tumor suppressor gene (PTCH). Previous studies showed this gene alteration in DCs; this can possibly be implicated in the pathogenesis of the association found in this report. CONCLUSION: This report presented a case of bilateral DC in the mandible in a patient showing features of GGS. Therefore, this report verified the very rare association between DC and GGS. This may help dentists and physicians in reaching an accurate and early diagnosis of GGS.

Impacts of the Triple bristles three-sided sonic powered toothbrush on tooth shade, plaque control and gingival health.

OBJECTIVES: To evaluate the efficacy of the Triple bristles three-sided sonic powered toothbrush in plaque removal and its impact on tooth shade and gingival health, and to compare this with a conventional manual toothbrush. METHODS: Fifty two participants (26 males and 26 females; mean age [SD] = 22.48 [1.52], SE = 0.210, 95% CI = 22.06-22.90) were recruited into this controlled within-subject, randomized, two-treatment, 1-month crossover and examiner-blinded observational study between October 2020 and January 2021 in the School of Dentistry, University of Jordan. Within each participant, the upper and lower jaws were randomized to receive a brushing protocol either with the Triple bristles three-sided sonic brush or with a soft manual standard toothbrush with flat trimmed bristles. Tooth shades were recorded for upper and lower anterior and premolar teeth. The Turesky-Modified Quigley-Hein Plaque Index (TMQHPI) and bleeding on probing (BOP) were evaluated at study baseline, 1 week and 1 month after applying the brushing protocol. RESULTS: Both tested brushes were associated with significant reduction in plaque scores and BOP (p < 0.05). The Triple bristles brush was more effective in reduction in plaque and BOP in the lower jaw and among females than the manual brush (p < 0.05). CONCLUSIONS: The Triple bristles brush was more superior for reduction in plaque and probing on bleeding in the lower jaw and among females.

COVID-19 and Dentistry: An Updated Overview of Dental Perspectives and a Recommended Protocol for Dental Care and Emergency Dental Treatment.

AIM AND OBJECTIVE: This manuscript aims to provide an overview of the coronavirus disease-2019 (COVID-19) pandemic from dental perspectives, and presents standards and guidelines of dental care provision based on available research in this field as well as clinical experience and practice. BACKGROUND: The current COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is spreading around the globe and interferes with the provision of dental care for many individuals from different communities and backgrounds. A search for the literature on PubMed, ISI Web of Science, Scopus, EMBASE, and Cochrane Library from March 1, 2020 to December 30, 2020 was conducted. Also, the bibliographies included in the indicated articles were used to identify further literature. Recommendations by health authorities in different countries were also consulted. RESULTS: COVID-19 is causing many fatalities and is disrupting people's daily life and the economy in many countries around the world. Due to the potential of cross-infection through dental treatments, especially dental aerosol generation procedures, the dental profession has been disrupted during this pandemic. Dental care provision has been ceased completely or partially (limited to emergency or urgent treatment) in most countries around the world. Until this pandemic is controlled by new suitable treatments and/or vaccination, there is an urgent need to adopt immediate guidelines and standards for the safe provision of dental care to meet patients' demands, especially for the dental aerosols. CONCLUSION: Guidelines and standards for dental treatment amidst the COVID-19 pandemic are required. This manuscript provides an overview of the COVID-19 pandemic from dental perspectives and presents standards and guidelines of dental care provision based on available research in this field as well as clinical experience and practice. CLINICAL SIGNIFICANCE: This manuscript provides guidelines and standards for dental treatment and clinical management within dental settings amidst the COVID-19 pandemic, and resembles part of the quest to set the golden standards for dental care during the current circumstances.

Women in Maxillofacial Surgery and Otolaryngology; Career Obstacles and Success Factors.

ABSTRACT: Little is known on career factors and expectations for female oral and maxillofacial surgeons (OMFS) in developing countries. The study aimed to explore career perceptions of females in 2 related surgical specialties: oral and maxillofacial surgery and otolaryngology (ENT) with a focus on career obstacles and success factors. A structured questionnaire was distributed to female surgeons working in Jordan in the 2 surgical specialties. Questions addressed socio-professional characteristics and career-promoting and hindering factors. All surgeons registered in both specialties were invited. A total of 56 surgeons participated in the survey. Age range was 29 to 55 years (mean = 38.55 ±â€Š5.799). Significantly more OMFS surgeons were single (P = 0.000) younger (P = 0.003), and had fewer years of experience (P = 0.01) than ENT surgeons. Significantly more ENT surgeons perceived the "hard working" attribute and "better communication skills" as career-promoting factors (P = 0.04, P = 0.015, respectively). Further, significantly more ENT surgeons believed that females in the surgical profession help in changing the traditional surgical stereotype linked with the male gender (93.8% ENT in contrast to 75% OMFS, P = 0.047), and expressed a preference for female mentors (48% ENT in contrast to 0% OMFS, P = 0.000). The results of this study indicate that female OMFS surgeons have different socio-professional characteristics and perceptions to their peers in ENT surgery, and this mainly manifested in professional experience, marital status, and important career perceptions. They seem to lack confidence in female participation and promotion of the surgical career, and they show preference for having exclusively male mentors.

Unexpectedly low levels of dental morphological asymmetry suggesting developmental resilience amongst living Jordanians: A cone beam computed tomography study.

The objective was to determine the degree of fluctuating asymmetry in the expression of 13 dental morphological traits among adult Jordanians. Cone beam computed tomography images for the dentitions of 150 adult Jordanians (67 males, 83 females; age range = 18-58, mean ages 28.2, SD = 10.0 years) were studied in 2017. The traits were classified using the Arizona State University dental anthropology system, and dichotomized according to the most widely accepted criteria to define trait presence. Asymmetry was assessed using three different methods: percentage of discordance including bilateral absence cases (PDIBAC), percentage of discordance excluding bilateral absence cases (PDEBAC), and inter-side correlation (ISC) using Kendall's tau coefficient. Fisher's exact test was used to assess sexual dimorphism in the degree of asymmetry. The mean PDIBAC and the mean ISC for all the traits considered are 4.1% and 0.837, respectively. For traits observed on key teeth (mesial members of teeth districts) the mean PDIBAC and the mean ISC are 3.0% and 0.860, respectively; and for those observed on variable teeth (distal members of teeth districts) the mean PDIBAC and the mean ISC are 6.5% and 0.783, respectively. No statistically significant difference was found in the degree of asymmetry between sexes. The overall low degree of asymmetry found in the present sample (4.1%) compared to the world range of 5-15% may indicate great ability of its individuals to buffer the adverse effects of environmental stresses affecting the living Jordanians during early tooth development.

Age and gender variations in the cone-beam computed tomographic location of mandibular canal: Implications for mandibular sagittal split osteotomy

Background: Mandibular sagittal split osteotomy (MSSO) may incur unfavorable split and sensorineural injuries. Knowledge of the anatomic location of the mandibular canal (MC) and bone thickness in the region of interest for MSSO, and the possible variations by age and gender can assist in avoiding such complications. Purpose: To study the location of the MC and bone thickness in the region of MSSO by cone-beam computed tomography (CBCT) radiographs and to evaluate the possible variations by age and gender in a Jordanian population. Material and Methods: This retrospective radio-anatomical study examined all CBCT radiographs for patients treated over three years at the University of Jordan Hospital, Amman, Jordan. Distances from the MC to the cortical external surfaces and MC diameter (MCD) were measured by a reliable observer at three predetermined regions for MSSO: region (A) [mandibular foramen area], region (B) [mandibular angle area] and region (C) [directly mesial to the second molar]. Gender and age differences in all measurements were then compared using non-parametric Mann-Whitney U test. Results: The final study radiographs comprised a total of 202 CBCT belonged to a cohort of 202 subjects; 91 males (45.1%) and 111 (54.9%) females, with mean age (± SD) of 42.94 ± 18.54 years (range 18-90 years). Whereas only the bone thickness superior, buccal and inferior to MC in regions (B) and (C), and MCD in the three regions exhibited significant (p < 0.05) gender differences, all measured distances exhibited statistically significant (p < 0.05) differences between young and adult patients. Conclusion: The location of MC and bone thickness in the region of MSSO were significantly variable according to age, but exhibited sexual diamorphism only in regions (B) and (C). This fundamental knowledge should be considered during MSSO planning

Relationship Between Dental Students' Personality Profiles and Self-reported Oral Health Behaviour.

PURPOSE: The objective of this study was to investigate the relationships between oral health behaviour and personality profiles among dental students. MATERIALS AND METHODS: One hundred six consecutive (pre-)clinical dental students (58 females and 48 males) were recruited for this observational study. Participants' oral health behaviour was evaluated using the Hiroshima University-Dental Behavioral Inventory (HU-DBI). The NEO Five Factor Inventory (NEO-FFI) was used to assess the participants' personality profiles. Main outcome measures were personality dimensions measured by NEO-FFI (neuroticism, extraversion, openness, agreeableness, and conscientiousness) and oral health behaviours measured by HU-DBI (dental visits, toothbrushing, oral health awareness, and oral hygiene practices). Statistical significance was set at p < 0.05. RESULTS: All participants were completely analysed. The students' level of education and age had no relationship to the HU-DBI and NEO-FFI scores (p > 0.05). The conscientiousness personality scores were associated with better oral health attitude and behaviour (p = 0.018). CONCLUSIONS: Higher scores of the conscientiousness personality dimension were associated with better oral health attitudes and behaviour. Therefore, it is recommended to consider assessment of personality dimensions when oral health attitudes and behaviours are evaluated. Personality profiles might affect oral health behaviour and attitudes of dental care providers. This interaction should be considered as it might potentially impact professionals' capacities to offer oral health care, and this would influence patients' oral health.

Efficacy of intraligamentary anesthesia in maxillary first molar extraction.

INTRODUCTION: Infiltration anesthesia (IA) is the method to anaesthetize maxillary teeth successfully. In contrast, intraligamentary anesthesia (ILA) has been used as supplementary anesthesia during tooth extraction, particularly when regional block anesthesia has failed. In this study, we compare the efficacy of and patient satisfaction with ILA vs IA when extracting maxillary first molar teeth. METHODS: Forty patients were enrolled in this study and 80 maxillary first molars extracted. All patients served as their own control, with ILA as the experimental side and IA as the control side. The two techniques were compared for efficacy using a visual analog scale (VAS) and patient satisfaction compared using a verbal rating scale (VRS). RESULTS: The mean VAS pain score for extraction using ILA was lower than that for IA (20.30±3.18 and 13.93±1.95 mm, respectively; P<0.001). For injection pain, the mean VAS pain score in the ILA side was higher than the IA side (42.28±4.51 and 31.73±3.1 mm, respectively; P<0.001). VRS results showed a higher number of patients who felt that pain during ILA was greater than expected compared with IA. CONCLUSION: IA appears less painful during injection compared with ILA, and provides sufficient pain relief during extraction. However, ILA can be used when IA fails to achieve the desired pain suppression, as it provides higher extraction-pain relief.

A simple method to locate mandibular foramen with cone-beam computed tomography and its relevance to oral and maxillofacial surgery: a radio-anatomical study.

PURPOSE: The mandibular foramen (MF) cannot be palpated clinically and its location is variable at the medial surface of mandibular ramus. Nevertheless, determining its exact location is very important to the oral and maxillofacial surgeon for the relevant anesthetic and surgical ramus procedures. The aim of this study was to analyze the position of MF using cone-beam computed tomography (CBCT) to help the surgeon in identifying reliable 'target area' for the inferior alveolar nerve (IAN) block and 'safety zone' for mandibular ramus osteotomies approached extra-orally. MATERIALS AND METHODS: This radio-anatomical study examined all CBCT radiographs for patients treated over 2 years. Distances from MF to the anterior (A) and posterior (P) borders of the ramus, mandibular incisura (MI), mandibular notch (MN), and mandibular occlusal plane (O) were measured by a reliable examiner, followed by calculation of ratios to determine the horizontal and vertical position of MF. Patients' details were then recorded. Student's t test and One-Way-ANOVA test were used to analyze data. RESULTS: A total of 210 CBCT radiographs were included and belonged to 210 subjects; 91 males (43.3%) and 119 (56.7%) females, with mean age (± SD) of 43.70 ± 19.08 years. The horizontal and vertical positions of MF differed significantly (P < 0.001) according to age, but generally calculated at least 40% of AP and MIMN distances from P and MI, respectively. CONCLUSION: This study suggested the '40% rule' to locate the 'target area' for IAN block and 'safety zone' for ramus osteotomies approached extra-orally.

Impaction of lower third molars and their association with age: radiological perspectives.

BACKGROUND: Third molars are the most commonly impacted teeth, and their extraction is the most commonly performed procedure in oral and maxillofacial surgery. The aim of the present study is to describe the pattern of mandibular third molar impaction and to define the most appropriate age for prophylactic extraction of mandibular third molar teeth. METHODS: A total of 1198 orthopantomographs (OPGs) with 1810 impacted lower third molars were reviewed by two authors. The pattern of eruption in relation to patient's age was examined using standard radiographic points and angles. Statistical analysis was performed using SPSS for Windows release 16.0 (SPSS Inc., Chicago, IL, USA). RESULTS: In patients older than 20 years, vertical pattern of impaction was the most common (21.4%); while in young patients; horizontal impaction was more common (21.3%). Furthermore, there was a constant pattern of increase in Pell-Gregory ramus class 1 with increasing age, as the prevalence of class 1 was 0% at age 18 years compared to 54.9% at the age of 26 years. CONCLUSION: Frequency of vertical impaction of lower third molars was seen more at an older age (> 20 years) in this study, with an increase in the retromolar space. Late extraction of mandibular third molar teeth (i.e. after the age of 20) is therefore recommended when prophylactic extraction is considered.

Factors predictive of the onset and duration of action of local anesthesia in mandibular third-molar surgery: a prospective study.

The aim of this study was to assess the influence of patients' and surgical variables on the onset and duration of action of local anesthesia (LA) in mandibular third-molar (M3) surgery. Patients scheduled for mandibular M3 surgery were considered for inclusion in this prospective cohort study. Patients' and surgical variables were recorded. Two per cent (2%) lidocaine with 1:100,000 epinephrine was used to block the nerves for extraction of mandibular M3. Then, the onset of action and duration of LA were monitored. Univariate analysis and multivariate regression analysis were used to analyze the data. The final cohort included 88 subjects (32 men and 56 women; mean age ± SD = 29.3 ± 12.3 yr). With univariate analysis, age, gender, body mass index (BMI), smoking quantity and duration, operation time, and 'volume of local anesthetic needed' significantly influenced the onset of action and duration of LA. Multivariate regression revealed that age and smoking quantity were the only statistically significant predictors of the onset of action of LA, whereas age, smoking quantity, and 'volume of local anesthetic needed' were the only statistically significant predictors of duration of LA. Further studies are recommended to uncover other predictors of the onset of action and duration of LA.

Periodontal ligament injection versus routine local infiltration for nonsurgical single posterior maxillary permanent tooth extraction: comparative double-blinded randomized clinical study.

AIM: The aim of this study was to evaluate the efficacy of, and patients' subjective responses to, periodontal ligament (PDL) anesthetic injection compared to traditional local-anesthetic infiltration injection for the nonsurgical extraction of one posterior maxillary permanent tooth. MATERIALS AND METHODS: All patients scheduled for nonsurgical symmetrical maxillary posterior permanent tooth extraction in the Department of Oral and Maxillofacial Surgery at the University of Jordan Hospital, Amman, Jordan over a 7-month period were invited to participate in this prospective randomized double-blinded split-mouth study. Every patient received the recommended volume of 2% lidocaine with 1:100,000 epinephrine for PDL injection on the experimental side and for local infiltration on the control side. A visual analog scale (VAS) and verbal rating scale (VRS) were used to describe pain felt during injection and extraction, respectively. Statistical significance was based on probability values <0.05 and measured using χ2 and Student t-tests and nonparametric Mann-Whitney and Kruskal-Wallis tests. RESULTS: Of the 73 patients eligible for this study, 55 met the inclusion criteria: 32 males and 23 females, with a mean age of 34.87±14.93 years. Differences in VAS scores and VRS data between the two techniques were statistically significant (P<0.001) and in favor of the infiltration injection. CONCLUSION: The PDL injection may not be the alternative anesthetic technique of choice to routine local infiltration for the nonsurgical extraction of one posterior maxillary permanent tooth.

Factors affecting oral health determinants in female university students: a cross-sectional survey in Saudi Arabia.

Objective This study aims at investigating factors affecting oral health patterns, attitudes and health risk behaviors among female university students. Methods An online questionnaire was distributed to female university students in Al Madinah in the western region of Saudi Arabia. Students were requested to answer questions on demographic data, oral hygiene practices, dental attendance, smoking history, practice of sports and body weight and height. Results Two hundred and fourteen students participated with age range of 18-31 years (mean = 21.64 ± 1.72 years). Oral hygiene habits were reported by a percentage of 97.2%, 34.6%, 30.8% and 19.2% who used a tooth brush, dental floss, mouthwash, and a miswak (a teeth cleaning twig made from the Salvadora persica tree), respectively. The only factor that was significantly associated with a good oral hygiene level was a university major of non-healthcare specialties (p = 0.009). Conclusion It is concluded that female university students use various oral hygiene methods, however, dental attendance is poor and a number of health risk factors are noticed like smoking, lack of practicing sport and unhealthy body mass index (BMI).

Age prediction in the adult based on the pulp-to-tooth ratio in lower third molars: a cone-beam CT study / Predicción de edad en el adulto basada en la proporción pulpa-a-diente en terceros molares inferiores: un estudio por TC de haz de cono

Estimation of age-at-death is an integral part of the identification process of individuals in many forensic odontology cases where their identity cannot be determined by visualization or other ways. Dental age estimation in the adult is more challenging as most of the dentition is completely developed by 18 years of age. This study employs a mesio-distal (MD) pulp-to-tooth ratio taken at the neck of lower third molars (LM3) to provide an estimation of age at the time of radiographic imaging based on the well-known fact that pulp volume tends to decrease with advancing age due to continued apposition of secondary dentine throughout adulthood. A total of 155 Cone-beam computed tomography (CBCT) radiographs of LM3s for a random sample of 155 Jordanian Arabs (80 females, 75 males; age range= 18-58 years, mean age= 28.2 years, SD =10.0 years) were used. Both pulp and tooth MD diameters were measured at the neck. MD pulp-to-tooth ratios for LM3s were linearly regressed against age. Statistically significant negative association was found between an individual's age at the time of imaging and the MD pulp-to-tooth ratio taken at the neck. Specifically, the strength of the association is r= -0.361, which means only 13.0 % of the variation in age can be explained by the MD pulp-to-tooth ratio taken at the neck. Therefore, it was concluded that MD pulp-to-tooth ratio taken at the neck of LM3s is not a reliable predictor of chronological age in adults, possibly due to the large variation in the timing of LM3 development.

La estimación de la edad es una parte integral del proceso de identificación de los individuos, en muchos casos en odontología forense donde la identidad no puede ser determinada por visualización u otras formas. La estimación de la edad dental en el adulto es aún más difícil ya que la mayor parte de la dentición se desarrolla completamente a los 18 años de edad. Este estudio emplea una relación mesio-distal (MD) de pulpa a diente tomada a nivel del cuello de los terceros molares inferiores (LM3) para proporcionar una estimación de la edad en el momento de la imagen radiográfica basada en que el volumen de pulpa tiende a disminuir con el avance de la edad debido a la continua posición de la dentina secundaria a lo largo de la edad adulta. Se examinaron un total de 155 radiografías de LM3 en una muestra aleatoria de 155 árabes jordanos (80 mujeres, 75 varones), rango de edad = 18-58 años, edad media = 28,2 años, DE = 10,0 años. Específicamente, la fuerza de la asociación es r=0,361, lo que significa que sólo el 13,0 % de la variación en la edad puede explicarse por la proporción pulpa-a-diente.

Waterpipe Tobacco Smoking Among Dental Practitioners: Prevalence and Health Perceptions.

BACKGROUND: Waterpipe tobacco smoking prevalence, practice, and the associated health perceptions among dental practitioners have not been previously reported. This study aims to determine the prevalence of waterpipe smoking among dental practitioners and to evaluate their awareness of health hazards of waterpipe smoking, particularly the adverse effects on oral health. METHODS: This was a cross-sectional questionnaire-based survey among dental practitioners. Surveyed dental practitioners practiced dentistry in the holy city of Al-Madinah Al-Munawarah, a city in the Central-Western Region of Saudi Arabia, and the study was conducted during March 2015. The questionnaire consisted of questions on demographic data, history and practices of tobacco use, and perceptions toward the health hazards of smoking. Dentists were approached at their work places and invited to participate. Descriptive statistics were used to describe the sample's demographic and smoking characteristics, while cross-tabulation and chi-square test were used to determine the statistical significance of association between the groups (P ≤ 0.05). RESULTS: One hundred dental practitioners participated in the survey, with 55 males and 45 females. Twenty-six percent indicated that they were waterpipe smokers. Male gender and cigarette smoking were the only factors to be significantly associated with waterpipe smoking (P = 0.008 and P = 0.000, respectively). Most participants stated that waterpipe smoking is harmful to health, and the most commonly reported health hazard was respiratory disease, which was reported by 81% of participants. CONCLUSIONS: Prevalence of waterpipe smoking among dental practitioners is comparable to adult populations but lower than younger populations of university students. Health awareness of dental practitioners regarding waterpipe smoking was judged to be insufficient.

The mental foramen II: radiographic study of the superior-inferior position, appearance and accessory foramina in Iraqi population / El foramen mental II: estudio radiográfico de la posición superior-inferior, aspecto y forámenes accesorios de una población Iraquí

Accurate information regarding the vertical location and appearance of the mental foramen, and the presence of accessory foramina, can have clinical significance, such as reducing complications that may occur during many oral surgical procedures involving the mental area. Geographic variations were reported in these variables. The aim was to evaluate the above-mentioned variables in an Iraqi sample. Five hundred eighteen panoramic radiographs of a random Iraqi sample (257 males, 261 females, average age= 46.5 years) were evaluated with regard to the above-mentioned variables, as well as the symmetry of the foramen regarding these variables. The area below the apices of mandibular premolars, and the continuous type were the most frequent vertical location and appearance of the mental foramen, respectively. Age advancement was found to be associated with an increase in the frequency of more inferior positioning and continuous appearance. The vertical position and appearance were asymmetrical in 16.2 % and 20.1 % of cases, respectively. Symmetry in the vertical location was statistically significant between sexes (P= 0.035), and young and old ages (P= 0.000). Symmetry in the appearance was found statistically significant (P= 0.025) only between the two age groups. Accessory foramina were recorded in 7.3 % of cases. The most common vertical location and appearance of the mental foramen on panoramic radiographs in this group are below the apices of mandibular premolars, and continuous type, respectively. This is in consistence with the findings of previous studies on other populations. The mental foramen usually has symmetrical vertical location and appearance. Accessory foramina are recorded in a percentage lower than that recently reported in some regional countries.

La información precisa acerca de la localización vertical, apariencia del foramen mental y la presencia de forámenes accesorios, puede tener importancia clínica, como la reducción de las complicaciones que pueden ocurrir durante muchos procedimientos quirúrgicos orales relacionados con el mentón. Las variaciones geográficas fueron reportadas en estas variables. El objetivo fue evaluar las variables anteriormente mencionadas en una muestra iraquí. Fueron evaluadas 518 radiografías panorámicas de una muestra aleatoria de Irak (257 varones, 261 mujeres, edad media = 46,5 años) con respecto a las variables antes mencionadas, así como la simetría del foramen con respecto a estas variables. El área por debajo de los ápices de los premolares mandibulares y el tipo continuo, fueron la localización vertical y apariencia del foramen mental más frecuentes, respectivamente. La edad avanzada se asoció con un aumento en la frecuencia de posicionamiento más inferior y de apariencia continua. La localización vertical y la apariencia fueron asimétricas en 16,2 % y 20,1 % de los casos, respectivamente. La simetría en la localización vertical fue estadísticamente significativa entre sexos (p= 0,035), y entre jóvenes y viejos (P= 0,000). La simetría en apariencia sólo fue estadísticamente significativa (p= 0,025) entre los dos grupos de edad. Se registró presencia de forámenes accesorios en un 7,3 % de los casos. La localización vertical del foramen mental más común en las radiografías panorámicas de este grupo están por debajo de los ápices de los premolares mandibulares, y respecto a la apariencia, el tipo continuo fue el más común. Esto está en coherencia con los resultados de estudios anteriores en otras poblaciones. Los forámenes mentales tienen una localización vertical y apariencia que suelen ser simétricas. Los forámenes accesorios se registran en un porcentaje inferior al informado recientemente en algunos países de la región.

Antifungal prescribing pattern and attitude towards the treatment of oral candidiasis among dentists in Jordan.

AIM: The aim of this study was to evaluate the attitude of Jordanian dentists towards the treatment of oral candidiasis and their current antifungal prescribing habits, shedding more light on the possible influence of their socio-professional factors on the pattern of prescribing and practice. METHODS: A structured validated questionnaire was developed and tested; it was then emailed to a random sample of 600 Jordanian dental practitioners during the period of this cross-sectional survey. The questionnaire recorded practitioners' personal details and their attitude and prescribing of antifungal therapy for oral candidiasis. Statistical significance was based on probability values of <0.05 and was measured using the chi-square and Fisher's exact tests. Multiple logistic regression analysis was used to analyse the influence of respondents' socio-professional factors on their attitude towards oral candidiasis. RESULTS: Of the 423 questionnaires returned, only 330 were included. The attitude of respondents was significantly influenced by their experience [odds ratio (OR) = 0.14; P < 0.001] and workplace (OR = 4.70; P < 0.001). Nystatin was the most commonly prescribed antifungal agent (78.2%), followed by miconazole (62.4%), which was prescribed for topical use. Systemic antifungals were prescribed by 21.2% of respondents, with a significant (P < 0.05) association with the country in which their qualification was obtained. CONCLUSION: The attitude towards the treatment of oral candidiasis is much better among the least-experienced dentists working in private practice. Nystatin and miconazole are the most popular choices of antifungal agents among Jordanian dentists.

Sublingual varices in relation to smoking, cardiovascular diseases, denture wearing, and consuming vitamin rich foods.

OBJECTIVES: To identify potential risk factors such as smoking, cardiovascular diseases (CVD), denture wearing, and consuming vitamin rich foods, and its relation to the development of sublingual varices (SLV). METHODS: This cross-sectional observational study was conducted on patients who attended the Department of Dentistry at The University of Jordan Hospital, Amman, Jordan between February and May 2013. Clinical examinations and inspections of 391 patients (203 males and 188 females), 13-74 years of age were conducted to determine the presence of SLV. Sublingual varices were classified into 2 categories: grade 0 (few or none visible), and grade one (moderate or severe). Frequency distributions of both SLV and risk factors were obtained. Multiple logistic regression analysis and Chi-square test were used to analyze the influence of individual risk factors on the incidence of SLV. RESULTS: There were 88 subjects (22.5%) who had SLV. In the multivariate logistic regression model, SLV were significantly associated with age (odds ratio [OR]: 2.27, p=0.008) with highest occurrences in the eighth decade of life, gender (OR: 2.74, p=0.001), smoking (OR: 2.93, p=0.002), denture wearing (OR: 2.03, p=0.044), and CVD (OR: 4.01, p=0.00). CONCLUSION: The presence of SLV could be indicative of some potential risk factors including old age, female gender, and denture wearing, and may alert the dental clinician to recognize underlying systemic conditions, particularly CVD.

The mental foramen I: radiographic study of the anterior-posterior position and shape in Iraqi population / Foramen mental I: estudio radiográfico de su posición antero-posterior y forma en población iraquí

Accurate information regarding the horizontal location and shape of the mental foramen can have clinical significance, such as reducing complications that may occur during maxillofacial surgical procedures involving the mental area. Geographic variations were reported in these variables. The aim was to study the horizontal position and shape of the mental foramen, as seen on panoramic radiographs of an Iraqi sample, to assess difference in these variables between sexes and age groups, and to assess symmetry of the mental foramen. 518 panoramic radiographs of a random Iraqi sample (257 males, 261 females, average age=46.5 years) were evaluated with regard to the horizontal location, shape and symmetry of the mental foramina. The area between the long axes of the two mandibular premolars, and the round type were the most frequent horizontal location and shape of mental foramen, respectively. Age advancement was found to be associated with an increase in the frequency of more posterior positioning and irregular shape. The horizontal position and shape were asymmetrical in 21.6% and 31.6% of cases, respectively. The Symmetry in horizontal location and shape of mental foramina were found statistically significant between sexes (P=0.041), and between young and old age groups (P=0.001), respectively. The most common horizontal location and shape of the mental foramen on panoramic radiographs in this group are between the two premolars, and the round type, respectively. This is in consistence with the findings of previous studies on other populations. The mental foramina have usually symmetrical horizontal locations and shapes.

Información precisa sobre la ubicación horizontal y forma del foramen mental puede tener importancia clínica en la reducción de complicaciones durante procedimientos quirúrgicos maxilofaciales que involucran el área mental. Fueron reportadas variaciones geográficas en relación a estas variables. El objetivo fue estudiar la posición horizontal y forma del foramen mental, a partir de 518 radiografías panorámicas de una muestra aleatoria en sujetos de Irak (257 varones, 261 mujeres; edad media= 46,5 años), quienes fueron evaluados con respecto a la posición horizontal, forma y la simetría de los forámenes mentales. En individuos de edad avanzada se encontró una asociación con un aumento en la frecuencia de un posicionamiento posterior y con forma irregular. La posición horizontal y forma del foramen fueron asimétricos en 21,6% y 31,6% de los casos, respectivamente. La diferencia hallada en relación a la simetría en posición horizontal y forma de los forámenes mentales fue estadísticamente significativa entre sexos (p=0,041), y entre los grupos de edad jóvenes y mayores (P=0,001), respectivamente. Se encontró con mayor frecuencia la posición horizontal entre los ejes longitudinales de los dos premolares mandibulares, y la forma circular, en relación a la posición antero-posterior y forma del foramen, respectivamente. Estos fueron resultados similares a estudios anteriores sobre otras poblaciones. Los forámenes mentales son simétricos, respecto a su ubicación horizontal y su forma.

Current sedation practice among general dental practitioners and dental specialists in Jordan: an example of a developing country.

PURPOSE: The study reported here aimed to identify current sedation practice among general dental practitioners (GDPs) and specialist dental practitioners (SDPs) in Jordan in 2010. METHODS: Questionnaires were sent by email to 1683 GDPs and SDPs who were working in Jordan at the time of the study. The contact details of these dental practitioners were obtained from a Jordan Dental Association list. Details on personal status, use of, and training in, conscious sedation techniques were sought by the questionnaires. RESULTS: A total of 1003 (60%) questionnaires were returned, with 748 (86.9%) GDPs and 113 (13.1%) SDPs responding. Only ten (1.3%) GDPs and 63 (55.8%) SDPs provided information on the different types of treatments related to their specialties undertaken under some form of sedation performed by specialist and/or assistant anesthetists. Approximately 0.075% of the Jordanian population received some form of sedation during the year 2010, with approximately 0.054% having been treated by oral and maxillofacial surgeons. The main reason for the majority of GDPs (55.0%) and many SDPs (40%) not to perform sedation was lack of training in this field. While some SDPs (26.0%) indicated they did not use sedation because of the inadequacy of sedative facilities. CONCLUSION: Within the limitations of the present study, it can be concluded that the provision of conscious sedation services in general and specialist dental practices in Jordan is inconsistent and inadequate. This stresses the great need to train practitioners and dental assistants in Jordan to enable them to safely and effectively perform all forms of sedation.
