OBJECTIVE: This study aimed at carrying out a radiographic analysis on the prevalence of dental anomalies of number (agenesis and supernumerary teeth) in permanent dentition, in different subphenotypes of isolated cleft palate pre-adolescent patients. METHODS: Panoramic radiographs of 300 patients aged between 9 and 12 years, with cleft palate and enrolled in a single treatment center, were retrospectively analyzed. The sample was divided into two groups according to the extension/severity of the cleft palate: complete and incomplete . The chi-square test was used for intergroup comparison regarding the prevalence of the investigated dental anomalies (P < 0.05). RESULTS: Agenesis was found in 34.14% of patients with complete cleft palate and in 30.27% of patients with incomplete cleft palate. Supernumerary teeth were found in 2.43% of patients with complete cleft palate and in 0.91% of patients with incomplete cleft palate. No statistically significant difference was found between groups with regard to the prevalence of agenesis and supernumerary teeth. There was no difference in cleft prevalence between genders within each study group. CONCLUSION: The prevalence of dental anomalies of number in pre-adolescents with cleft palate was higher than that reported for the general population. The severity of cleft palate did not seem to be associated with the prevalence of dental anomalies of number.

Summary Background/Objectives This retrospective study evaluated the prevalence of dental anomalies of number in different subphenotypes of isolated cleft palate. Materials/Methods The sample comprised 26 individuals with submucous cleft palate (group S) and 68 individuals with complete cleft palate (group C) aged between 9 and 12 years from a single centre. Panoramic radiographs were evaluated regarding the presence of dental anomalies of number in permanent teeth. Intergroup comparison was performed using chi-square tests (P &lt; 0.05). Results Tooth agenesis was found in 34.61 and 36.76 per cent of group S and group C, respectively. The most commonly missing teeth were the maxillary second premolar, maxillary lateral incisor, and mandibular second premolar. Supernumerary teeth were found in none and 1.47 per cent of the individuals with submucous and complete cleft palate, respectively. No statistically significant difference was found between groups for the frequency of tooth agenesis and supernumerary teeth. Limitations Only dental anomalies of number were evaluated. Conclusions/Implications Individuals with submucous and complete cleft palate showed similar prevalence for tooth agenesis and supernumerary teeth. Dental anomalies frequency seems not to be a discriminator for subphenotypes of cleft palate.

ABSTRACT Objective To compare the level of satisfaction in the use of wraparound Hawley and thermoplastic maxillary retainers. Materials and Methods The study sample included 70 orthodontic patients (24 males and 46 females), who were in the retention stage (mean age = 20.80 years). All patients wore the two types of maxillary retainer for 1 month each, along with a 3×3 fixed mandibular retainer. After the use of each retainer, the patients responded to a questionnaire evaluating the level of satisfaction with their use of the maxillary retainer. Intergroup comparison was performed by independent t tests. Chi-square test was used to evaluate preference for the type of retainer by gender. Results The thermoplastic retainer was better for swallowing and the wraparound Hawley appliance was better for hygiene and durability. The other factors evaluated (adaptation, speech, comfort, esthetics, satisfaction, and fitting) did not show significant differences between the retainers. There was also no significant difference in preference for the appliances. Conclusions Regarding the overall satisfaction and the preference, there was no difference between the wraparound Hawley and thermoplastic retainers. The wraparound Hawley appliance was better in hygiene and resistance than the thermoplastic retainer; and the thermoplastic appliance was better than the wraparound Hawley for swallowing fluids and saliva.

ABSTRACTObjectives: The aim of this study was to determine the prevalence of double teeth, hypodontia, microdontia, and hyperdontia of primary teeth in Turkish children.Methods:The study group comprised 1149 children (554 girls, 595 boys). The children were examined in twelve local nurseries in Sivas, Turkiye. Clinical data were collected by four dentists according to Kreiborg criteria; which includes double teeth, hypodontia, microdontia, and supernumerary teeth. Statistical analysis of the data was performed using the chi-square test.Results: Dental anomalies were found in 2.0% of children. The distribution of dental anomalies were significantly more frequent (P=.023) in boys (2.9%, n=17) than in girls (1.1%, n=6). In relation to anomaly frequencies at different ages, no difference was found (P = .760).Conclusions: Double teeth were the most frequently (1.3%) observed anomaly. The other anomalies followed as; 0.3% supernumerary teeth, 0.3% microdontia, 0.2% hypodontia. Identification of dental anomalies in the anterior region at an early age is of great importance for esthetic and orthodontic treatment planning. (Eur J Dent 2012;6:178-183)

The aim of this study was to characterize dental anomalies. The pretreatment records (photographs and radiographs) of 2897 patients (41.4% males and 58.6% females) were utilized to detect dental anomalies. The dental anomalies studied were related to number, size and shape, position, and eruption. A Chi-square test was carried out to detect associations between dental anomalies, jaw, and sex. A total of 1041 (36%) of the subjects manifested at least one dental anomaly. The prevalence of all dental anomalies was jaw-dependent and greater in the maxilla, except for submerged and transmigrated teeth. The most frequently missing teeth were the maxillary lateral incisor (62.3%) and the mandibular second premolars (60.6%). The most frequent supernumerary teeth were the incisors in the maxilla (97%) and the first premolars in the mandible (43%). Dental anomalies are more frequent in the maxilla and mainly involve the anterior teeth; in the mandible, however, it is the posterior teeth. These differences can be attributed to the evolutionary history of the jaws and their diverse development patterns.

Abstract Objective The purpose of this study was to find the prevalence of dental abnormalities in patients with third molar agenesis, and a comparison was made for the prevalence of those anomalies within the north Indian natives. Materials and Methods Pretreatment records of 518 patients were collected. Out of 518 patients whose records were analyzed, 472 patient records were selected on the basis of inclusion and exclusion standards. Panoramic radiographs and dental casts were analyzed in patients who had an absence of at least one third molar in which absence of any other tooth, presence of supernumerary teeth, presence of impacted canines, and peg-shaped lateral incisors were further assessed. The prevalence of these anomalies was compared with a randomly selected group of patients with presence of third molars that served as controls. Statistical analysis was done using the chi-square test (p < 0.05) and odds ratio. Results The incidence of third molar nondevelopment was found to be 19.2%. The presence of other anomalies was 39.5% in patients with third molar nondevelopment, and difference was statistically significant. The occurrence of impacted canines in patients with absence of third molars was 22%, and presence of third molars was 6.6%. The presence of other dental anomalies, that is, supernumerary teeth and tooth agenesis, was 7.7% in the agenesis group, which was also higher than that in the control group (3.3%) but was not statistically significant. The incidence of peg-shaped lateral incisors was similar in both the groups. Conclusion Impacted canines and total dental anomalies are more often related with absence of third molars than with the presence of third molars.

Introduction: Malocclusion is one of the commonest problem in dentistry and the knowledge on its prevalence on particular population group is very important to plan oral health activities. The objective of this study is to assess the prevalence of malocclusion in school going children of Parsa district, Nepal, and to compare the same with previous study. Materials and Method: The sample consisted of 250 males and 210 females (total of 460 subjects) aged between 6 to 17 years. Subjects without any previous orthodontic treatment and with no dental anomalies were included in this study. Census sampling was done for the patient visiting orthodontic from November 2018 to March 2019. Classification of malocclusion was based on Angle’s classification of malocclusion. Collected data were entered in Microsoft Excel 2007 and converted into Statistical Package for Social Science (SPSS) Version 11.5 for statistical analysis. For descriptive statistics, percentage and proportion, were calculated, also tabular presentation were performed. For inferential statistics, Chi square test were used for intergroup comparison. Result: School going children of Parsa district, Nepal suggests 50.47% female and 45.6% of male exhibits Angle’s Class I malocclusion, 29.04% female and 30% male exhibits class II pattern, 11.4% female and 12.0% male exhibits class III pattern. The other findings reported in the study were, the occurrence of crowding of teeth more in males whereas the occurrence of spacing is more in females. Conclusion: Majority of the subjects in the study had Class I malocclusion. Only 9.04% female and 12.4% of male showed normal class I occlusion. The occurrence of crowding of teeth more in males whereas the occurrence of spacing is more in females. This may be due to the incidence of missing tooth is more in females.

Introduction: Dental anomalies are commonly seen during regular dental check-up. It occurs due to abnormal morphodifferentiation of teeth during different stages of tooth development. The purpose of this study was to find out the of dental anomalies among orthodontic patients of Kathmandu, Nepal. Materials & Method: A total of 601 patients (242 males and 359 females) of aged 10 to 35 years (mean age= 16.42±3.42 years) who require orthodontic treatment were selected. The patients were assessed clinically and dental panoramic radiographs were evaluated for disturbance in number and other anomalies. A chi-square test was used to determine the difference in the prevalence of dental anomalies between genders and among different classes of malocclusion. Result: The prevalence of dental anomalies was 15.3% that is 92 participants were exhibited at least one dental anomaly among 601 orthodontic patients. Among dental anomalies, hypodontia was the most prevalent (7.48%) followed by hyperdontia (2.99%), microdontia (2.16%), macrodontia (0.66%), transposition (0.66%), taurodontism (0.49%), double teeth (0.33%), amelogenesis imperfecta (0.33%) and dentinogenesis imperfecta (0.16%). The prevalence of oligodontia was 0.33%. There were no statistically significant difference in prevalence of anomalies in between gender and among different classes of malocclusion. Conclusion: Prevalence and distribution of some dental anomalies in orthodontic patients of Kathmandu differed from other studies. Maxillary lateral incisor was the most commonly missing and microdontic tooth. Orthodontists have the responsibility to observe each patient carefully for dental anomalies to correct or improvise this condition without any complications.

The purpose of the present study was to evaluate the prevalence of teeth malposition (rotated) in Brazilian patients with oral clefts and to contribute to the definition of subphenotypes. This study included 317 patients with nonsyndromic cleft lip with or without cleft palate. Tooth malposition was assessed clinically, through radiographs, and medical history records for each individual. Only teeth malpositions outside the area of the clefts were included. Comparisons were assessed by cross-tabulation and standard chi-square test, and statistical significance was set at p≤0.05. Cleft lip and palate was more prevalent in males, while cleft palate was more common in females. Regarding the presence of tooth malposition, of the 317 patients, 92 (29.02%) had at least one tooth with the dental anomaly. Tooth malposition was more common in patients with cleft lip and palate (16.1%), followed by, respectively, cleft palate (6.9%) and cleft lip (6%) (p=0.112). The highest occurrence of tooth malposition was in the mandible and involved the canines (p<0.01). Few studies have investigated the prevalence of tooth malposition in individuals with nonsyndromic cleft lip with or without cleft palate. Our results confirmed the highest occurrence of dental anomalies, particularly tooth malposition, in patients with oral clefts. Our findings also highlight that there was a higher occurrence of this condition in the mandible and not the maxilla.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Abstract Background There is uncertainty surrounding the prognostic value of peritoneal cytology in low-risk endometrial cancer, especially in laparoscopic surgery. The objective of this retrospective study is to determine the prognostic significance of positive peritoneal cytology among patients with low-risk endometrial cancer and to compare it between laparoscopic surgery and conventional laparotomy. Methods From August 2008 to December 2019, all cases of pathologically confirmed stage IA grade 1 or 2 endometrial cancer were reviewed at Osaka Medical College. Statistical analyses used the Chi-square test and the Kaplan–Meier log rank. Results A total of 478 patients were identified: 438 with negative peritoneal cytology (232 who underwent laparotomy and 206 who undertook laparoscopic surgery) and 40 with positive peritoneal cytology (20 who underwent laparotomy and 20 who received laparoscopic surgery). Survival was significantly worse among patients with positive peritoneal cytology compared to patients with negative peritoneal cytology. However, there was no significant difference among patients with negative or positive peritoneal cytology between laparoscopic surgery and laparotomy. Conclusion This retrospective study suggests that, while peritoneal cytology is an independent risk factor in patients with low-risk endometrial cancer, laparoscopic surgery does not influence the survival outcome when compared to laparotomy.
