It is very rare (2%-6% cases) for a mandibular canine to have two root canals and the incidence of finding two roots with two root canals in a mandibular canine that too bilaterally is almost negligible. This case report discusses the presence and multidisciplinary management of such rarest configuration in both mandibular canines of a female patient. This case shows the importance of recognition of anatomical variations in successful accomplishment of root canal treatment.

Prevalence of Traumatic Injuries to Primary Anterior Teeth among Children aged 2-6 Years in National Capital Region of Delhi, India

Sharma HK, Gupta K, Singh S

J Contemp Dent Pract, 2022 Jul 01;23(7):720-724.

PMID: 36440519

AIMS: The aim of this study was to assess subject wise and tooth wise distribution and prevalence of traumatic injuries to the anterior teeth of 2- to 6-year-old children.

MATERIALS AND METHODS: A cross-sectional survey was performed. Primary maxillary and mandibular anterior teeth of 1,800 children aged between 2 years and 6 years, who attended 20 pre-schools in National Capital Region Delhi, India, were examined by a single examiner, and a questionnaire was filled in person by the parent/guardian. Andreasen's classification was used to classify the traumatic injuries. The Chi-square test was used to statistically analyze the variation in traumatic dental injuries (TDIs) with age and gender. Multiple logistic regression was used to determine the influence of independent variables on the occurrence of TDIs.

RESULTS: The prevalence of TDIs was 17%. Significant and highly significant differences were found between boys and girls for cause and location of trauma (p < 0.05) and tooth type involved (p < 0.001) with boys being more prone to such injuries. The commonest cause of injury was due to falls and the location was playground. The teeth most commonly affected were the maxillary central incisors (36.9%) followed by maxillary lateral incisors (3.3%), and the least affected were the maxillary and mandibular canines (0.3%).

CONCLUSION: The prevalence of traumatic injuries to the anterior teeth in 2- to 6-year-old children in National Capital Region of Delhi, India, was 17%. There is a need to run educational programs to increase parents' awareness of the risks of dental trauma and emphasize preventive measures.

CLINICAL SIGNIFICANCE: Parents should be made aware of the widespread prevalence, risk factors, and consequences of trauma to primary dentition, so that they can seek appropriate care timely. The time elapsed between injury and dental care is of utmost importance.

Accessory roots and root canals in human anterior teeth: a review and clinical considerations

Ahmed HM, Hashem AA

Int Endod J, 2016 Aug;49(8):724-36.

PMID: 26174943 DOI: 10.1111/iej.12508

Anterior teeth may have aberrant anatomical variations in the number of roots and root canals. A review of the literature was conducted using appropriate key words in major endodontic journals to identify the available reported cases as well as experimental and clinical investigations on accessory roots and root canals in anterior teeth. After retrieving the full text of related articles, cross-citations were identified, and the pooled data were then discussed. Results revealed a higher prevalence in accessory root/root canal variations in mandibular anterior teeth than in maxillary counterparts. However, maxillary incisor teeth revealed the highest tendency for accessory root/root canal aberrations caused by anomalies such as dens invaginatus and palato-gingival groove. Primary anterior teeth may also exhibit external and internal anatomical variations in the root, especially maxillary canines. Therefore, dental practitioners should thoroughly assess all teeth scheduled for root canal treatment to prevent the undesirable consequences caused by inadequate debridement of accessory configurations of the root canal system.

A comparison of interalar width and intercanine distance in Malay males and females

Dharap AS, Tanuseputro H

Anthropol Anz, 1997 Mar;55(1):63-8.

PMID: 9161682

The interalar width of the nose and the intercanine distance were measured in 266 Malay subjects (111 males and 155 females) randomly selected from the students of the School of Medical Sciences. University Sains Malaysia in Kota Bharu, Malaysia. The mean interalar width of the nose in male subjects was 39.8 +/- 2.3 mm (range 34-45 mm) and in female subjects 36.2 mm +/- 2.2 mm (range 30-41 mm). There is a statistically significant difference (t = 12.9: p < 0.05) in the nasal width between male and female Malay subjects. This agrees with the findings of other similar studies that males have wider noses than females. The mean maxillary intercanine distance in male subjects was 36.7 = 2.6 mm (range 30-42 mm) and in female subjects 36.2 = 2.3 mm (range 30-42 mm). The anterior maxillary arch is significantly wider in Malay subjects compared to Chinese from Singapore (Keng 1986) as p < 0.05 and to Caucasians (Sawiris 1977) as p < 0.05. There is a significant correlation (r = 0.312; p < 0.05) between the nasal width and the intercanine distance in female subjects but not in male subjects.

Fulltext Large male proboscis monkeys have larger noses but smaller canines

Matsuda I, Stark DJ, Saldivar DAR, Tuuga A, Nathan SKSS, Goossens B, et al.

Commun Biol, 2020 09 21;3(1):522.

PMID: 32958853 DOI: 10.1038/s42003-020-01245-0

The uniquely enlarged noses of male proboscis monkeys are prominent adornments, and a sexually selected male trait. A recent study showed significant correlations among nose, body, and testis sizes and clear associations between nose size and the number of females in a male's harem. However, to date, the analyses of other common male traits, i.e., canines, are lacking. Whereas male nose size had a positive correlation with body size, we unexpectedly found a negative correlation between body and canine sizes. We explain this by an interaction between sexual and natural selection. Larger noses in males may interfere with the use of canines, thereby reducing their effectiveness as weapons. Additionally, longer canines are opposed by natural selection because the larger gape it imposes upon its bearer reduces foraging efficiency, particularly in folivores. This unique case of decoupling of body and canine size reveals that large canines carry an ecological cost.

Nik-Noriah, Nik-Hussein

J Clin Pediatr Dent, 1992;16(2):112-4.

PMID: 1498045

A case report showing the eruption of the left maxillary and mandibular permanent cuspids in a six-year-old boy, is presented. In addition, the dental age of all the permanent cuspids as seen by the eruption and tooth development suggested that the cuspids are comparable to those seen in a 13 to 14 year-old-boy. A search of the literature has not revealed any such reports.

Lactate dehydrogenase activity during tooth movement under 1.0 N and 1.5 N continuous force applications

Shahrul Hisham Zainal Ariffin, Nurfathiha Abu Kasim, Rohaya Megat Abdul Wahab, Abdul Aziz Jemain

Sains Malaysiana, 2013;42:99-105.

The aim of this study was to observe the pattern of lactate dehydrogenase (LDH) activity in GCF and the rate of tooth movement at two different orthodontic forces (1.0 N and 1.5 N). Twelve subjects participated in this study and was chosen based on the inclusion criteria. Each subject received forces of 1.0 N and 1.5 N for tooth movement either on the left or right side of the maxillary canine. GCF sample was collected at mesial and distal sites of the canines before applying the appliance (week 0) and every week for 5 weeks after tooth movement (week 1 to week 5) where baseline activity served as control. LDH activity was assayed spectrophotometically at 340 nm. The tooth movements were measured from casted study models. LDH specific activity at mesial sites in 1.0 N and 1.5 N force groups, respectively increased significantly (p<0.05) only on week four and throughout the treatment when compared with baseline. At distal sites, LDH specific activity with 1.5 N was higher than 1.0 N throughout the five weeks of tooth movement. LDH specific activity with 1.5 N force increased at both mesial (week 2) and distal sites (week 3) with significant different (p<0.05) when compared with 1.0 N force. Tooth movement with 1.5 N showed significantly faster (p<0.05) at the end of week 5 when compared with 1.0 N. LDH has the potential as a biological marker of inflammation during tooth movement.A force of 1 N was more suitable to be used although less tooth movement was produced because less inflammation caused by the force can be useful in orthodontic treatment for patients with stabilised periodontal diseases compared with 1.5 N force.

Autotransplantation of maxillary canine following removal of compound odontome: a case report

Zaman JQ, Yahaya N, Razali M, Ibrahim N, Nor GM, Ramli R

Singapore Dent J, 2007 Dec;29(1):41-5.

PMID: 18472529

Obstruction remains as an important cause of failure in the eruption of a tooth. In this article, a 15-year-old girl was presented with retained upper left primary canine (63) and first primary molar (64), while the contralateral permanent canine (13) and premolars (14 and 15) have erupted. Upon radiographic examination, a mass which was diagnosed later to be compound odontome was detected. The treatment consisted of surgical removal of the odontome, extraction of the primary canine (63) and left permanent canine (23), and transplantation of the permanent canine (23). The management of this case and the literature related to autotransplantation are discussed.

Fulltext Ferret: The Animal Of Choice In Dental Experiments

Alani, A.H., Abdul Aziz Abdul Razak

Ann Dent, 1996;3(1):-.

MyJurnal

The canine teeth of the mature ferret have closed apices. They are easily accessible for operating purposes and are sufficiently large, allowing conventional cavity preparation techniques to be prepared using ordinary dental instruments. Handling of the ferret is relatively easy since it becomes quite tame after a period of time. The body weight in male is greater and the teeth larger than those of the female. The cost of purchase and maintenance of the ferret is also inexpensive. For all these reasons, the ferret male is animal of choice in dental experiments.

Fulltext Comparison of cheiloscopy, odontometric, and facial index for sex determination in forensic dentistry

Priyadharshini KI, Ambika M, Sekar B, Mohanbabu V, Sabarinath B, Pavithra I

J Forensic Dent Sci, 2019 2 13;10(2):88-91.

PMID: 30745784 DOI: 10.4103/jfo.jfds_102_17

Background: The "gender determination" which is an important human identification procedure not only helps in establishing the biological profile from skeletal and dental remains but also in facial reconstruction of unidentified victims.

Aim: The aim of this study is to analyze predominant types of lip prints (cheiloscopy), accuracy of mandibular canine index (MCI) (odontometric), and facial index in the study population and to identify whether any correlation among the above parameters could help forensic dentistry in solving crimes.

Materials and Methods: A pilot study was conducted in 100 individuals, 50 males and 50 females aged between 20 and 25 years. For each individual, the lip prints, MCI, and facial index measurements were recorded on the same day analyzed by two observers. All the analysis was done using SPSS version 14 assessed using t-test and Chi-square test.

Results: Type II pattern of lip prints is observed as common pattern among male and female. There is no significant difference in Odontometric analysis. The mean value of facial index analysis in both genders shows highly significant.

Conclusion: A large-scale study is required in order to validate our results to arrive at definitive results and value.

Proximal tooth surface quality and periodontal status

Yusof Z

J Oral Rehabil, 1991 Jan;18(1):95-102.

PMID: 2051253

The aim of this study was to determine the periodontal status in relation to the quality of the adjacent proximal tooth surface. The gingival index (GI) and probable pocket depth (PD) were measured in 144 contra-lateral pairs of sound vs. restored and 95 contra-lateral pairs of sound vs. carious surfaces in 124 patients. The restorations studied were silver amalgams and tooth-coloured filling materials, the margins of which were supragingival or level with the gingival margins. The results showed that the GI and PD were greater for both restored and carious tooth surfaces than for the contra-lateral sound surfaces. When all the teeth were grouped together, the differences in the mean values of GI and PD were statistically significant at the P less than or equal to 0.05 level. A comparison between restored and carious (non-paired) tooth surfaces revealed higher mean values of GI and PD for the latter, which were highly significant at the P less than 0.001 level. Thus the present study shows that proximal tooth surface quality influences the health status of the adjacent periodontium.

Dental anomalies in the primary dentition: distribution and correlation with the permanent dentition

Nik-Hussein NN, Abdul Majid Z

J Clin Pediatr Dent, 1996;21(1):15-9.

PMID: 9161200

The study consisted of analysis of all cases of anomalies in the primary dentition that were seen or treated by the authors in the Department of Children's Dentistry and Orthodontics. A total of 79 occurrences of anomalies was seen in 65 children. The anomalies detected were double teeth, hypodontia and supernumerary teeth. Radiographic examinations of the affected children showed that over 60% of the cases with anomalies in the primary dentition are associated with anomalies of the succadeneous permanent dentition. All subjects with hypodontia of the primary dentition presented with hypodontia of the permanent dentition. However, anomalies of the permanent dentition were seen in 59% of subjects with primary double tooth and 50% of subjects with primary supernumerary tooth.

Pre-eruptive intracoronal dentin defects of permanent teeth

Nik NN, Abul Rahman R

J Clin Pediatr Dent, 2003;27(4):371-5.

PMID: 12924738

This study was conducted to determine the prevalence of pre-eruptive intracoronal dentin defects from panoramic radiographs from a group of children and young adults aged 20 years and below. The radiolucent lesions were noted with regard to which teeth were affected, the location of the defects and the size of the defects relative to the width of dentin. Out of 1007 radiographs examined, 275 (27.3%) have pre-eruptive dentin defects. The prevalence of anomaly among males was 28.4% as compared to 26.2% among females. However, the difference between genders was not significant, thus subsequent results have been combined. Of 275 subjects with dentin radiolucencies, 243 subjects (88.7%) had only one affected tooth, 30 subjects (10.9%) had two teeth affected and 2 subjects (0.7%) had three affected teeth. The tooth prevalence of the anomaly was 2.1% and most of the lesions occurred as a single occurrence on the affected tooth. Within each tooth type, the highest tooth prevalence of intracoronal dentin defect was found in the upper first premolar (5.1%). More than half of the lesions extended less than 1/3 of the width of the dentin thickness. The high prevalence of the condition indicates the need for increased awareness and recognition of this during radiographic examination of teeth in the pediatric age group in early pre-eruptive stages so that early detection and diagnosis can be made and treatment can be done at the most appropriate time.
