Background: Adequate knowledge of timing and pattern of the third molars is essential. The molars are often used to supplement human maturity indicators for school attendance, social benefits, employment, and marriage, differentiating the juvenile from the adult's status in criminal law cases, unidentified cadavers and human remains when birth records are not adequate or not available. BROAD OBJECTIVE: The study was carried out to investigate the emergence status of the third molar tooth among 15 to 16 year-old Tanzanian adolescents.
Methodology: A cross-sectional community based study was carried out among secondary school children in Ilala District, Dar es Salaam, Tanzania. This study included 203 adolescents aged 15-16 years old of whom 54% were boys and 46% girls. It was a subsample of randomly selected Tanzanian youths who were part of a larger sample of 869 children from randomly selected 16 schools from different parts of the district covering the whole range of socio-economic background.
Results: More third molars were already in occlusion in girls (11-13%) than in boys (3-4%) while girls had more third molars emerged into the oral cavity than boys did. The girls had about 15% to 20% of the four third molar teeth emerged in the oral cavity compared to about 3% to 18% in boys. Except for the mandibular right third molar, all the differences in emergence of the third molars between girls and boys were statistically significant. More mandibular third molars had emerged than the corresponding maxillary ones.
Discussion And Conclusions: Third molars were in occlusion in 3-13% of the Tanzanian youths aged 15-16 years indicating earlier emergence than in Caucasian populations. Hence, the need for specific third molars emergence standard tables molars is evident. More studies both cross sectional and longitudinal type involving a larger sample to provide the median and mean ages, rate and pattern of emergence of the third molars in the Tanzanian youth populations are recommended.

Background: The current study attempts to assess the impact of third molar impaction on external root resorption (ERR) of the adjacent second molars. We aimed to determine the prevalence, severity, and associated factors with ERR in a sample of panoramic radiographs.
Material And Methods: A retrospective cross-sectional study was carried out at teaching hospital.
Odontogenic cutaneous fistulas are abnormal connections between the oral cavity and skin, often mistaken for skin infections. They typically result from dental infections but may also arise from salivary gland issues, tumors, or congenital anomalies. Accurate diagnosis is essential to prevent complications like infection, osteomyelitis, and discomfort.

Background: A broken bur retained in the lower jaw is an uncommon complication that occurs during the extraction of the impacted mandibular third molar. The purpose of this retrospective study was to investigate the clinical characteristics of the broken burs and review our experience with the removal of the broken burs in these cases.
Methods: All patients, who suffered the broken bur remained in the lower jaw due to the extraction of the impacted mandibular third molar and presented to our hospital from July 2019 to July 2024, were included in this retrospective study.

Introduction: This is a double clinical trial conducted to study the patient satisfaction and comfort during and after surgical removal of impacted mandibular 3rd molar using Piezo electric tips.
Material And Methods: Two groups of 25 each [14 (56 %) males and 11 (44 %) females] and [18 (72 % males and 07 (28 %) females] represented the Rotary and Piezo groups respectively with bilateral impactions. one side of the patient is operated by piezo and the other side by rotary instrument after a gap of 2-3 week between the procedures.

Purpose: This study aimed to analyze changes in anxiety and comfort levels at each perioperative stage during third molar extraction under single-agent intravenous midazolam sedation, and to clarify how these conditions at each perioperative stage affect postoperative satisfaction.
Patients And Method: 115 who requested extraction of 1 ~ 4 third molars under single-agent intravenous midazolam sedation were targeted. These patients were administered a questionnaire survey one week after surgery.
