Position of the mental foramen in Singaporean Malays and Indians

Neo J

Anesth Prog, 1989 Nov-Dec;36(6):276-8.

PMID: 2490061

The position of the mental foramen of the local Malays and Indians in Singapore was determined from a series of orthopantomograms. The most frequent location does not conform to the position cited in many anatomy, surgery, and dental anesthesia texts as being below and between the apices of the lower premolars. This data has implications in the teaching and practice of dental anesthesia. In both these races, the median location is just below the second premolar.

Lingam AS, Koppolu P, Abdulsalam R, Reddy RL, Anwarullah A, Koppolu D

Ann Afr Med, 2023;22(1):49-54.

PMID: 36695222 DOI: 10.4103/aam.aam_213_21

AIM: The study aims to determine the frequency of positioning errors, record the number of diagnostically inappropriate images, and assess the quality of panoramic radiographs.

MATERIALS AND METHODS: In this study, a total of 2629 patients for whom orthopantomogram were selected out of 3900 new patients between August 2020 and June 2021. The positioning errors of the radiographs were evaluated and categorized into ten groups. The quality of the radiographs is further assessed as "Excellent," "Diagnostically Acceptable," and "Diagnostically Unacceptable."

RESULTS: Out of the total radiographs, 32.8% had no errors, and 77.2% of the radiographs had one or more positioning errors. The radiographs were analyzed in detail, and the errors found in the panoramic radiographs were recorded. The most common positioning error observed in the radiograph was error 8, failure to place the tongue close to the palate.

CONCLUSION: The results and evaluation inferred that attention to patient positioning and focusing on reducing diagnostically indecent images could improve the quality of panoramic radiographs. Proper instructions to the patient, patient preparation, appropriate positioning of the patient, and the technician's skill plays a vital role in reducing diagnostic errors in Panoramic Radiography.

Fulltext Florid cemento-osseous dysplasia as a possible aggravating factor in a case of trigeminal neuralgia.

Siar, C.H., Ibrahim, N., Omar, A.N., Abdul Rahman, Z.A.

Ann Dent, 2010;17(1):21-24.

MyJurnal

Differential diagnosis of orofacial pain is crucial, as the course of each process and its clinical management varies markedly. A case is illustrated here of trigeminal neuralgia in a 49-year-old Indian female whose complaint was initially diagnosed as dental pain leading to sequential extractions of her right mandibular and maxillary molars but with no pain abatement. Subsequent neurological assessment diagnosed her complaint as trigeminal neuralgia but pain remained poorly controlled even with high doses of carbamazepine and gabapentin. A dental referral and orthopantomographic examination revealed multifocal sclerotic masses in her jaws, suggestive of florid cemento-osseous dysplasia (FCOD). Right mandibular incisional biopsy confirmed the diagnosis. A decision was made to curette the right mandibular masses and lateralised the right inferior dental nerve. Follow-up disclosed considerable pain reduction. This case raises the issue as to whether the sclerotic bone masses in FCOD may have caused nerve compression which
aggravated her neuralgic pain.

Fulltext Implant Survival between Endo-osseous Dental Implants in Immediate Loading, Delayed Loading, and Basal Immediate Loading Dental Implants a 3-Year Follow-up

Garg R, Mishra N, Alexander M, Gupta SK

Ann Maxillofac Surg, 2017 Jul-Dec;7(2):237-244.

PMID: 29264292 DOI: 10.4103/ams.ams_87_17

Introduction: With introduction of the term "ossteointegration of dental implant" by Branemark, advancement in implantology from 1957 to 2017 has come a long way with modification in implant type and in loading time. This study aims to evaluate the survival of endo-osseous immediate loading (IL) implant and basal IL implants in atrophic jaws with objective to compare implant survival in atrophic jaws for full mouth rehabilitation between endo-osseous IL versus endo-osseous delayed loading (DL) versus basal IL during 3-year follow-up.

Materials and Methods: Fifty-two (34 endo-osseous and 18 basal) implants were placed in 4 patients requiring full mouth rehabilitation in atrophic jaws. Case 1: Endo-osseous DL implants in upper and lower arch, Case 2: Endo-osseous IL implants in upper and lower arch, Case 3: Basal IL implant in upper and lower arch, and Case 4: Endo-osseous DL in upper arch and basal IL implant in the lower arch. Intraoperative evaluation was done on the basis of pain (visual analog scale [VAS]), operative time, and initial primary implant stability. Postoperative evaluation was done on pain (VAS), infection, radiographically successful implant (orthopantomogram), and patient satisfaction (Grade 0-10).

Results: All cases showed satisfactory results but more amount of intra- and post-operative pain was felt with immediate basal implants.

Conclusion: We believe that clinicians should comply with patient requests, and for this reason, we agree with some authors to use minimally invasive techniques and to avoid when possible esthetic or functional problems associated with the use of removable prosthesis after teeth extractions.

MyJurnal

The objectives of this study were to determine the normal mean value of the root-crown (R/C ratios) in Malay patients and their variations by gender and dental arch from orthopantomogram radiographs (OPGs). Two thousand nine hundred and twenty teeth with fully developed roots were measured from 112 OPGs. Subjects with history of maxillofacial trauma or orthodontic therapy were excluded. The mean age of the subjects was 19.1 (SD 2.08) years old for males while females 18.9 (SD 2.19) years old in the range from 15 to 22 years old. The intra-examiner reproducibility of the assessment method was good (Intraclass correlation coefficient 0.81). Results of this study showed that there was no significant difference between R/C ratios of males and females groups. However, the ratios of the antagonist teeth for both males and females were significantly greater in the mandible than in the maxilla (p

Archives of Orofacial Sciences, 2009;4(1):7-12.

MyJurnal

The aim of this study was to identify the position of impacted mandibular third molars based on the classifications of Pell & Gregory and Winter, the indications for extraction, and the relation of post-operative complications and position. Records of patients who attended Hospital Universiti Sains Malaysia between January and December 2007 for surgical removal of mandibular third molars were reviewed. The angulation type, width and depth of impaction were determined by reviewing the orthopantomograms. The indications of extraction and occurrence of any post- operative complications were recorded. A total of 238 impacted teeth were surgically extracted from 194 patients (97 males, 97 females). The reasons for extraction include recurrent pericoronitis (43.1%) followed by prophylactic purposes (33.5%). Mesioangular impactions accounted for 52.3% and Class IIA position of impaction accounted for 45.7% of extractions. The most common post-operative complication was persistent pain and swelling (14.7%) followed by trismus (4.1%) and dry socket (3.0%). There was no significant relationship between the angulation, width and depth of impaction and the occurrence of complication. Mesioangular type and Class IIA position of impaction were the most common impaction. Although the association was not significant, high frequency of post-operative complications was observed in mesioangular, horizontal, IIA and IIC positions.

Upon reviewing the literature, the prevalence of many systemic conditions such as diabetes,
hypertension, asthma and rheumatoid arthritis were reported to be high in Saudi Arabia. The relationship of these
conditions with tooth loss among Saudi population was not investigated. Therefore, the aim of the present study
is to explore the relationship between tooth loss and most common medical conditions among Saudi dental
patient. The study participants were 250 patients who were randomly selected from the College of Dentistry
database of King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) in Riyadh, Saudi Arabia.
Participants were requested to answer self-administered questionnaires related to their demographic as well as
general health questions concerned to the presence of systemic medical conditions. Missing teeth were
determined after examining the orthopantogram radiographs and reviewing the Romexis and SALUD databases.
Descriptive statistics, independent t-test and linear multiple regression model were performed using SPSS
software. The mean number of missing teeth among the study population was 5.8 teeth per person. The mean
number of missing teeth was higher among subjects with diabetes, hypertension, rheumatoid arthritis,
cardiovascular diseases, or osteoporosis compared to healthy individuals. A multiple linear regression analysis
model revealed that diabetes, hypertension and rheumatoid were significant predictors of missing teeth among
Saudi population. These results highlight the importance of the effect of medical conditions on oral health.

PMID: 29764822 DOI: 10.1136/bcr-2017-223586

A 51-year-old woman a known case of stage 2 breast carcinoma in 2006 and underwent left mastectomy performed in the same year presented with bilateral lower limb pain suggestive of spinal pathology, and left chin numbness, both of 2 weeks' duration. Examination revealed left mandibular hypoesthesia without any other sign or symptoms. Orthopantomogram was unremarkable apart from mild alveolar bone expansion at tooth 36 area, which was extracted 3 months earlier. Subsequently, a full-body positron emission tomography contrast enhanced computer tomography revealed hypermetabolic lesions of her axial (excluding skull) and appendicular skeleton. In the head and neck region, left mandibular foramen and oropharynx bilaterally showed increased metabolism suggestive of tumour metastasis. The diagnosis was numb chin syndrome secondary to mandibular metastasis. Apart from supportive treatment, she was started on palliative chemotherapy and radiotherapy. At the time of discharge, there were no active complaints other than the aforementioned hypoesthesia.

The clinical anatomy of accessory mandibular canal in dentistry

Ngeow WC, Chai WL

Clin Anat, 2020 Nov;33(8):1214-1227.

PMID: 31943382 DOI: 10.1002/ca.23567

The mandibular canal is a conduit that allows the inferior alveolar neurovascular bundle to transverse the mandible to supply the dentition, jawbone and soft tissue around the gingiva and the lower lip. It is not a single canal but an anatomical structure with multiple branches and variations. The branches are termed accessory, bifid or trifid canals depending on their number and configuration. A bifid mandibular canal is an anatomical variation reported more commonly than the trifid variant. Because of these variations, it is of the utmost importance to determine the exact location of the mandibular canal and to identify any branches arising from it prior to performing surgery in the mandible. This article reviews the prevalence, classification and morphometric measurements of these accessory mandibular canals, emphasizing their clinical significance.

Susuk, or charm needles, are inserted and worn subcutaneously in the face and other parts of the body, as they are believed to enhance beauty and youth, and for many other reasons such as treatment of headache, aches and pains in the joints, back or abdomen. The practice of inserting susuk is a traditional belief, genuinely cultural and superstitious, and common in the south-east Asian region. We present 13 cases of susuk, which was found incidentally on the radiographs as the patients came for various types of treatment at our centre.

Validity of Demirjian and Willems methods for dental age estimation for Malaysian children aged 5-15 years old

Nik-Hussein NN, Kee KM, Gan P

Forensic Sci Int, 2011 Jan 30;204(1-3):208.e1-6.

PMID: 20869825 DOI: 10.1016/j.forsciint.2010.08.020

BACKGROUND: One of the most commonly used method for dental age assessment is the method reported by Demirjian and coworkers in 1973. It was later modified by Willems and coworkers whereby they “performed a weighted ANOVA” in order to adapt the scoring system.
AIM: To evaluate the applicability of Demirjian and Willems methods for dental age estimation for Malaysian children and to correlate the accuracy of the findings with the chronology of tooth development of premolars and second molars.
MATERIALS AND METHODS: A total of 991 dental panoramic radiographs of 5-15-year-old Malaysian children were included in the study. The mean Demirjian and Willems estimated ages were compared to the mean chronological age.
RESULTS: The mean chronological age of the sample was 10.1±2.8 and 9.9±3.0 years for males and females respectively. Using the Demirjian method, the mean estimated dental age was 10.8±2.9 years for males and 10.5±2.9 years for females. For Willems method, the mean estimated age was 10.3±2.8 years males and 10.0±3.0 years respectively.
CONCLUSIONS: Willems method was more applicable for estimating dental age for Malaysian children. Overestimation in Demirjian method could be due to advanced development of second bicuspids and molars.
