Abstract Introduction: Knowledge of the growth status of patients is essential to formulate and initiate a precise treatment plan. This study aimed at determining the role of calcification of permanent mandibular teeth for the assessment of skeletal maturity. Methods: A cross-sectional study was conducted using lateral cephalograms and dental panoramic radiographs of 360 patients (ages 7-18 years) equally divided into six groups according to cervical vertebral maturation stages. Skeletal age was determined using Baccetti et al. method and dental age was calculated using Nolla and Demirjian methods. Results: Mean chronological stage at CS5 revealed a significant difference between male and female subjects (p= 0.003), which showed that the latter achieved skeletal maturity one year earlier than the former. A significant difference (p= 0.007) was found for dental age using Nolla’s stages at CS3, which showed females demonstrated a dental age of 1.4 years less than males. Mandibular canine showed the highest correlation with Demirjian index (DI) in males (rho = 0.818) and females (rho = 0.833). Mandibular second premolar showed the highest correlation with Nolla’s stages in males (rho = 0.654) and females (rho = 0.664). Conclusion: Comparisons between sexes revealed that females are skeletally and dentally advanced. The DI indicated stage F and Nolla’s stages identified stages 9, 10 to be indicative of CS2-3 for the mandibular canine and stages F and G and 9-10 for CS2-3 for the first premolars, second premolars and second molars, respectively.

Background: An attractive smile is often attributed to incisor alignment and proclined or retroclined incisors could contribute to a less aesthetic smile. Objectives: This study was aimed to evaluate the maxillary central incisor crown inclination, crown angulation and tooth size variation in aesthetic and unattractive smiles. Methods: This study was conducted among 100 females (equally divided into aesthetic and unaesthetic smile groups), aged between15 - 25 years, with Angle’s Class I normal occlusion and balanced profiles. Variations in maxillary central incisor crown inclination and angulation were measured on lateral cephalograms, photographs and the study models of the subjects. Variations in tooth morphology were also evaluated by measuring crown height and width in both groups. Mann-Whitney U test was performed to evaluate the difference between the aesthetic and unaesthetic smiles. P < 0.05 was considered as significant. Results: This study showed that incisor angulation was significantly higher in the unaesthetic group compared to the aesthetic group (P < 0.001). However, there was no statistically significant difference for the incisor inclination relative to the Palatal Plane between the aesthetic and unaesthetic smile groups (P = 0.086). In addition, there were significant differences between the aesthetic and the non-aesthetic groups regarding the central incisor height (P < 0.05). Conclusions: The findings of this study indicate that the possible variations in aesthetics are related to the ethnic elements that are associated with differences in crown angulations, as well as tooth size.

Objective: Gnathoschisis is the most common congenital craniofacial abnormality in patients with cleft lip and/or palate (CL and/or P). The panoramic radiograph is one means to establish a diagnosis and treatment plan with two-dimension photograph. The cone-beam computed tomography (CBCT) is one means of supporting the maxillofacial to get a three-dimension photograph. The aim of this study was to determine the difference in the results of the use of panoramic photos and CBCT in evaluation before and after gnathoplasty surgery.Material and Methods: This is an observational descriptive research with cross-sectional study method. All samples that meet the suitable criteria are put in this research. The data gained by collecting status card at medical record installation about photo panoramic application in gnathoschisis patients was then compare to the examination with CBCT.Results: The result performed shows that there is a significant difference between panoramic and CBCT picture. The CBCT provide better evaluation about teeth age and segment position of jaw curve from the cleft size. While the panoramic photo provides a widely covered area to observe facial and teeth bone.Conclusion: The CBCT results are more accurate in evaluating gnathoplasty surgery than panoramic photo; however, exposure to the radiation should be considered.

Estimation of dental age in forensic odontology is crucial in biological dentistry Coronal Pulp Cavity Index (CPCI) as one method to check the correlation between the reduction of the coronal pulp cavity and chronological age. The present study aims to find out whether CPCI method can be used to estimate the dental age on lower second premolar and first molar with periapical radiographic analysis. The cross sectional study was conducted on 60 patients (30 males and 30 females) in the age range of 21 and 30 years. They were subjected to periapical radiographs on lower second premolar and first molar. The Coronal Pulp Cavity Height (CPCH) and Coronal Length (CL) was measured using vision measuring scope DC 3000 and electronic digital caliper. The values obtained were subjected into the formula of TCI = [CPCL × 100]/CL. The mean of TCI score and average chronological age were analyzed using paired T test to find out the correlation between the chronological age and the estimated dental age, P > 0.05 is considered as significant. There was no significant difference between the estimated dental age and chronological age in both lower second premolars (p=0.119) and first molars (p=0.224). CPCI method can be used to estimate the dental age on healthy lower second premolar and first molar.

Background: In recent years, age estimation in forensic medicine has become so important. Teeth are used to estimate age as valuable indicators. Objectives: This study aimed to compare Cameriere and Demirjian methods in estimating chronological age (Age) in an Iranian population and to develop a modified Cameriere method. Methods: In this cross-sectional study, we investigated a total of 486 panoramic radiographs of individuals aged 5 - 15 years adopted from two craniofacial radiology centers in Babol, northern Iran, in 2019. The dental age of subjects was assessed by Demirjian (DAge) and Cameriere (CAge) methods and compared with their chronological age. Also, a formula was designed based on the Cameriere method for our studied population, and the results of the original and modified Cameriere (MCAge) methods were compared. Results: The mean ± SD of Age (10.38 ± 2.30) had a significant difference with DAge (10.67 ± 2.33) and CAge (9.77 ± 2.01) (P < 0.001). The modified Cameriere formula was more accurate than Cameriere one, and MCAge was 10.38 ± 2.12, indicating no significant difference with Age (P = 0.993). Conclusions: According to our results, both Demirjian and Cameriere methods were not reliable for age estimation in the Iranian population. However, the modified Cameriere formula had a very high accuracy in estimating the age of the studied population.

The Difference

A cross sectional study was carried out within the lateral cephalograms on 100 Chinese teenage patients at the department of orthodontia in the second affiliated hospital of Dalian Medical University, CHINA in order to evaluate the Wits measurement as compared to ANB angle for identifying the anteroposterior skeletal discrepancy between maxilla & mandible and to determine the normal Wits value suitable for Caucasian descent whether it was applicable or not on the Chinese teenagers distributed according to sex, age & malocclusion variations. Non probability (purposive) sampling technique to collect 100 samples of lateral cephalometric radiographs and data were collected from the measurements of multiple planes & angles formed by adjoining various anatomic landmarks connecting to each other in those radiographs. Lateral cephalograms of those 100 subjects were divided according to gender, age & malocclusion type. In the sex group there were 43 males & 57 females. In the age group 68 patients’ ages were from 13 to 15 years and 32 patients’ ages were from 16 to 19 years. In the malocclusion group 41 patients had class I, 40 patients had class II & 19 patients had class III malocclusions. Statistical analyses were done by t-test (two independent samples) to detect the differences between two sex groups and also between the two age groups. One way ANOVA (analysis of variance) was applied to evaluate the differences of malocclusion classification. The results were statistically significant when p<0.05. Few results were also significant when compared to the level of p<0.01. Sex group showed statistically significant differences of some values like UFH, LFH, TFH & SN. Age group showed statistically significant values in case of LFH & L/TFHP. Malocclusion group showed significant value only for SNA. The research revealed that international Wits value of -1.0 mm for males could be applicable to the males of Chinese teenagers as their average Wits measurements were also found the same in this study. But the international standardized Wits value of 0.0 mm for females couldn’t be applicable for Chinese teenage females as their mean value of Wits measurements was found to be -1.2 mm in this study probably due to the slight maxillary retrognathism of Chinese female descents. On the other hand the difference between the Wits appraisal of Chinese male & female teenagers was found to be -0.2 mm which couldn’t be considered as a major difference between them. So the normal existence of the Caucasian Wits value of a one mm discrepancy should be modified to -0.2 mm if we want to apply this on teenage patients of Chinese population.

ABSTRACT Aim The present study aimed to investigate the association between the tooth coronal index (TCI) and the pubertal growth stages (PGS) for children and adolescents. Materials and methods A cross-sectional study was performed using retrospectively collected panoramic and hand-wrist radiographs of 262 individuals (125 males, 137 females). The coronal height (CH) and the coronal pulp cavity height (CPCH) of the left mandibular teeth were measured. Then the TCI for which was calculated according to Ikeda et al (1985). The estimated TCI for individuals with the following PGS after Fishman (1987) are: SMI 4 (S), SMI 5 (DP3 cap), SMI 6 (MP3 cap) and SMI 7 (Mp5 cap). The associations between the TCI and the PGS were investigated by correlation coefficient of Spearman's rho, and the validity values for the PGS were computed. Results Significant correlations were noted between the simple TCI values for premolars and molars and the PGS, and the highest correlation was for the summed TCI for both first and second molars. Utilizing the validity values of the summed TCI for both first and second mandibular molars, the PGS can be predicted as follows: S stage when TCI is 49.17 or lesser, DP3cap stage when TCI is 43.52 or lesser, MP3cap stage when TCI is 36.73 or lesser, and Mp5cap stage when TCI is 26.84 or lesser. Conclusion The TCI values declined along with the maturational process in children and adolescents. The TCI for both first and second molars was the best predictor of the PGS. Clinical significance Panoramic photographs can be beneficial for prediction of the skeletal maturity and treatment planning without resorting to hand-wrist radiographs.

Dental Traits

Background and Objectives: Human identification is the forensic odontologist’s primary duty in the fields like violent crime, child abuse, elder abuse, missing persons and mass disaster scenarios. In each context, dental traits may produce compelling evidence to aid victim identity, suspect identity and narrow down the outcome of investigative casework. Sometimes it becomes necessary to apply some least known and less popular techniques in identification procedure where lip prints, rugae patterns and canine odontometrics can give us comparatively valid conclusions pertaining to person’s identification. This study elucidates the significance of cheiloscopy, palatoscopy and canine odontometry in sex prediction and discrimination. Materials and Methods: A cross- sectional study involving a total of 60 subjects, 30 males and 30 females were selected from the outpatient department of oral medicine and radiology. Lip prints were recorded using lipstick, palatal impressions were taken with alginate and odontometric measurements were taken with digital vernier calipers from every subject. All the obtained records were analyzed by two observers. Results: Reliability of lip prints was assessed using Kappa coefficient. Comparison of rugae patterns was done using Chi-square test. Mean canine and inter canine width was compared using t test. A p-value of <0.05 was considered significant. Statistically significant difference was found with the different lip print patterns analyzed in males and females, while no significant difference was observed in the rugae patterns but a significant difference in the mesio-distal width of mandibular canines in males and females was found with right mandibular canine(3.73%) showing greater sexual dimorphism compared to left mandibular canine(3.06%). Conclusion: This study shows the uniqueness of the lip prints and rugae patterns with the lip prints showing sensitivity of 81.7% giving reliable prediction of sex over palatoscopy. Hence, cheiloscopy along with the canine odontometrics aid in sex determination and can be considered as an ancilliary forensic tool in identification.

Open Apices

Background: Estimation of age has been a major factor in identification of an individual, either living or after death. Objective: To estimate and assess the dental age of children by measuring the open apices of the teeth using panoramic radiograph applying linear regression equation.  Methods: This was a retrospective cross-sectional study conducted on 50 children (25 boys and 25 girls) aged between 5-15 years. The seven left permanent mandibular teeth were assessed using panoramic radiographs which were collected from Medical Record Department, Manipal University, taken during the course of diagnosis and treatment. The number of teeth with closed apical and with open apical end of roots were examined and measured. The values were tabulated and placed on the linear regression equation proposed by Cameriere et al for the estimation of dental age. Result: The result showed no significant difference between the dental age (10.13±1.69 years) and the chronological age (10.31±1.75 years) (p=0.26). The method underestimated the mean age by 0.11 years and 0.23 years for the boys and girls, respectively. The paired sample t- test showed no significant difference between dental age and chronological age for boys (p=0.546) as well as for girls (p=0.351) Conclusion: The estimated age of children by measuring the open apices of the teeth using panoramic radiograph linear regression equation used in the European subjects closely matches with the chronological age in Asian subjects also. Keeping in context to validate more accurately the significance of linear regression equation, there is a need of larger sample size belonging to variety of ethnic and socioeconomic background.DOI: http://dx.doi.org/10.3126/hren.v12i1.11983Health Renaissance 2014;12(1):33-37
